Technical Field

The present invention relates to a Vital data (vita data) collection system, a Vital data relay system, and a Vital data collection method.

Background

In recent years, IoT (Internet Of Things) or IIoT (Industrial IoT) is attracting attention. These IoT and IIoT are technologies for connecting all objects (all hardware terminals such as sensors and instruments and devices) to the internet, collecting data of the objects acquired by the sensors to a cloud server, analyzing the collected data, and effectively using (feeding back) the analysis results for a specific purpose.

The IoT and the like described above are expected to be used in various fields as well as industrial fields. For example, patent documents 1 to 3 below disclose techniques for collecting vital data (for example, vital body information such as body temperature and heart rate) in a cloud server. By using the techniques disclosed in patent documents 1 to 3 as described above, for example, the health status of many people can be easily managed.

Patent document 1: japanese laid-open patent publication No. 2015-514512

Patent document 2: japanese Kokai publication No. 2017-511164

Patent document 3: japanese patent laid-open publication No. 2016-167141

Disclosure of Invention

Further, it is considered that the techniques disclosed in the above-mentioned patent documents 1 to 3 are applied to management of health status of workers working in a workshop or the like, process management of work, and the like. For example, it is conceivable to realize a system that can manage the health status of an operator, manage a work process, and the like if a sensor is attached to the body of the operator who works in a workshop or the like, and vital data measured by the sensor is uploaded to a cloud server. In the system as described above, the vital data measured by the sensor needs to be transmitted to the cloud server via a wireless (or partially wired) communication network. However, the communication state of wireless communication is not necessarily good depending on the working environment.

For example, as a certain work environment, there is a case where radio waves from a mobile phone base station are not reachable or hardly reachable (hereinafter, referred to as "special environment") such as outside the signal range of a mobile phone. As the special environment, for example, there are many places where the number of base stations of mobile phones is small and the mobile phones are far from the central portion of a city, such as mines, mountainous areas, on the ocean, and construction sites, and where work is performed over a wide range (several to several tens of kilometers of a square circle).

Conventionally, when data is transmitted in such a special environment, a method of transmitting data by providing a plurality of relays between a sensor and a communication base station (or a gateway capable of being communicatively connected to the communication base station) and transferring data by the plurality of relays can be used. However, in the conventional method as described above, in particular, as the work area becomes larger, more relays need to be installed, and thus there is a problem that the installation cost and the operation cost of the communication device increase.

In the special environment described above, a method of using a satellite communication line having a wider available area instead of using a mobile phone communication network is also conceivable, but in this case, there is a problem of an increase in communication cost. Further, although a fixed communication network (wired communication) is used instead of the mobile phone communication network, in this case, there is a problem that installation cost and operation cost of the communication equipment become higher particularly in a working environment where the working area is large.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a vital data collecting system, a vital data relay system, and a vital data collecting method, which can transmit data by effectively using a commercially available terminal while suppressing costs even in a special environment.

A vital data collecting system according to some embodiments collects vital data of an actor who acts in an environment where radio waves from a mobile phone base station do not reach or are not easily reached, the vital data collecting system including: a sensor carried by the actor for measuring vital data of the actor; a relay which is carried by the actor, acquires vital data of the actor measured by the sensor, and transmits the acquired vital data by low-power-consumption long-distance wireless communication; and a collection server that collects the vital data transmitted from the relay via a network. As described above, the vital data collecting system transmits vital data via the relay, and thus can transmit data by effectively using a commercially available terminal while suppressing costs even in a special environment.

In one embodiment, the repeater may include a 1 st repeater and a 2 nd repeater carried by the actor, the 1 st repeater acquiring the vital data measured by the sensor, transmitting the acquired vital data to the collection server via the mobile phone base station when wireless communication with the mobile phone base station is possible, transmitting the acquired vital data to the 2 nd repeater when wireless communication with the mobile phone base station is not possible, and the 2 nd repeater transmitting the vital data transmitted from the 1 st repeater to the collection server via the low-power consumption long-distance wireless communication. As described above, since the relay includes the 1 st relay and the 2 nd relay, even when the 1 st relay cannot transmit the vital data to the collection server, the vital data is transmitted to the collection server via the 2 nd relay. As described above, the vital data collecting system can transmit data by effectively using a commercially available terminal while suppressing the cost even in a special environment.

In one embodiment, the 1 st relay may transmit the acquired vital data by short-range wireless communication when wireless communication with the mobile phone base station is not possible, and the 2 nd relay may receive the vital data transmitted from the 1 st relay by the short-range wireless communication.

Thus, the vital data collecting system can transmit data by effectively using a commercially available terminal while suppressing the cost even in a special environment.

In one embodiment, the repeater may further acquire at least 1 of the position information, the time information, and the identification information of the actor or the sensor of the sensor in addition to the vital data and transmit the acquired data by the low power consumption long distance wireless communication, and the collection server may collect at least 1 of the vital data, the position information, the time information, and the identification information of the actor or the sensor transmitted from the repeater. Thus, the vital data collecting system can transmit the vital data and transmit other data in a special environment.

Thus, in the vital data collecting system, L oRA can be used for data transmission.

A vital data relay according to some embodiments is carried by an actor who acts in an environment where radio waves from a mobile phone base station do not reach or are not easily reached, and relays vital data of the actor, and includes: an acquisition unit that acquires vital data of the actor measured by a sensor; and a transmission unit that transmits the vital data acquired by the acquisition unit by low-power-consumption long-distance wireless communication. As described above, the vital data measured by the sensor is transmitted by the vital data relay. Therefore, according to the vital data relay, even in a special environment, it is possible to transmit data by effectively using a commercially available terminal while suppressing costs.

In one embodiment, the acquiring unit may receive and acquire the vital data transmitted by short-range wireless communication. As described above, the vital data is relayed by the short-range wireless communication. Thus, the vital data collecting system can transmit data by effectively using a commercially available terminal while suppressing the cost even in a special environment.

In one embodiment, the acquisition unit may further acquire at least 1 of position information, time information, and identification information of the actor or the sensor of the sensor in addition to the vital data, and the transmission unit may transmit at least 1 of the vital data acquired by the acquisition unit, the position information, the time information, and the identification information of the actor or the sensor. Thus, the vital data repeater can relay vital data and other data in a special environment.

As described above, the vital data relay system transmits the vital data via the relay, and thus, even in a special environment, it is possible to transmit the data by effectively using a commercially available terminal while suppressing costs. In addition, the vital data relay system can transmit the vital data via the 2 nd relay even when the 1 st relay cannot transmit the vital data to the collection server.

In one embodiment, the 1 st relay may transmit the acquired vital data by short-range wireless communication when wireless communication with the mobile phone base station is not possible, and the 2 nd relay may receive the vital data transmitted from the 1 st relay by the short-range wireless communication. As described above, in the vital data collecting system, vital data is transmitted from the 1 st relay to the 2 nd relay by the short-range wireless communication. Thus, the vital data collecting system can transmit data by effectively using a commercially available terminal while suppressing the cost even in a special environment.

In one embodiment, the 1 st relay and the 2 nd relay may transmit at least 1 of position information and time information of the sensor and identification information of the actor or the sensor in addition to the vital data. Thus, the vital data relay system can transmit vital data and other data in a special environment.

As described above, the vital data collection method transmits the vital data via the relay, and thus, even in a special environment, it is possible to transmit the data while suppressing costs and effectively using a commercially available terminal.

In one embodiment, the method may further include the step 2 of transmitting, when the repeater is capable of performing wireless communication with the mobile phone base station, the acquired vital data to the collection server via the mobile phone base station instead of the low-power consumption long-distance wireless communication. As described above, the 2 nd transmission step is provided, whereby the vital data is transmitted from the relay to the collection server via the mobile phone base station when the wireless communication between the relay and the mobile phone base station is enabled. As described above, the vital data collecting system can transmit data by effectively using a commercially available terminal while suppressing the cost even in a special environment.

In one embodiment, the 1 st transmission step and the 2 nd transmission step may be a step of transmitting at least 1 of the vital data, the position information and the time information of the sensor, and the identification information of the actor or the sensor, which are acquired in the acquisition step, and the collection step may be a step of collecting at least 1 of the vital data, the position information and the time information of the sensor, and the identification information of the actor or the sensor, which are transmitted from the relay.

[ Overall Structure of Life data collecting System ]

Next, the overall configuration of the life data collecting system 1 will be described with reference to the drawings.

Fig. 1 is a block diagram showing an overall configuration of a vital data collecting system 1 according to an embodiment. As shown in the figure, the vital data collecting system 1 includes a health watch 10, a wireless sensor 11, a short-range wireless communication path 15, a smartphone 20, a mobile phone communication network 25, a short-range wireless communication path 26, a communication conversion router 30, a low-power consumption long-range wireless communication path 35, a gateway 40, a mobile phone communication network 45, a cloud server 50, a communication network 55, and another system 60.

The vital data collecting system 1 according to the present embodiment is a system realized by cloud computing mainly for the purpose of grasping the health status of an operator working in a special environment, attendance management of the operator, and process management of work in the special environment.

In fig. 1, only 1 terminal group worn and held by a worker is shown, but actually, a plurality of workers exist in the work area, and each worker wears and holds the terminal group.

The term "cloud computing" as used herein refers to, for example, cloud computing that matches the definition (definition recommended by national institute of technology) described in a document identified by UR L (Uniform Resource L atom) as follows.http:// nvlpubs.nist.gov/nistlpubs/L economy/SP/nistspecialpublification 800-145. pdf

https://www.ipa.go.jp/files/000025366.pdf

The health watch 10 is a wearable device of a wristwatch type worn by the wrist of an operator working in a special environment. The health watch 10 includes various sensors, and vital signs of an operator can be sensed by the sensors. The vital sign sensing as used herein refers to a technique for measuring body temperature, pulse rate, blood pressure, exercise amount, body position, heart rate, electrocardiogram, and oxygen concentration in blood with various sensors.

The health watch 10 includes, in addition to sensors used for sensing vital signs, an acceleration sensor, a receiver for receiving radio waves of a GNSS (Global Navigation Satellite System) such as a gps (Global Positioning System) or a G L onass (Global Navigation Satellite System), and the like, and can measure the movement, position, and the like of the operator.

The health watch 10 has a communication function and can be connected to the smartphone 20 through the short-range wireless communication path 15. The health watch 10 transmits measurement data including position information, time information data, and identification information of an operator or the health watch 10 to the smartphone 20, for example.

The health watch 10 may be a wearable device that can perform the above-described life sensing and can communicate with the smartphone 20, or may not be a wristwatch type.

The wireless mounted sensor 11 is a sensor worn by an operator working in a special environment. The wireless mounted sensor 11 is directly attached to the clothing of the operator or the skin of the operator by a tape, a seal, or the like for wearing, for example. The wireless sensor 11 also senses vital signs of the operator, as in the case of the health watch 10. The wireless onboard sensor 11 has a communication function, as in the case of the health watch 10, and can be connected to the smartphone 20 via the short-range wireless communication path 15 to communicate measurement data to the smartphone.

Further, a plurality of wireless mounted sensors 11 of different types may be worn for 1 operator, for example. The wireless onboard sensor 11 is a device for supplementing the positioning of the function of the health watch 10, and is a device for measuring vital signs that cannot be measured by the health watch 10. Therefore, if all desired data can be acquired only by the health watch 10, the vital data collecting system 1 may be configured without the wireless sensor 11.

In the following description, the health watch 10 and the wireless mounted sensor 11 may be collectively referred to as "health watch 10 or the like".

In the following description, various measurement data (specifically, measurement data such as body temperature, pulse rate, blood pressure, exercise amount, body position, heart rate, electrocardiogram, and blood oxygen concentration) measured by the health watch 10 and the like will be collectively referred to as "vital data".

The short-range wireless communication path 15 is a communication path for performing short-range wireless communication. The short-range Wireless communication referred to herein is, for example, Bluetooth (registered trademark), Wi-Fi (registered trademark), or the like.

The smartphone 20 (1 st relay) is a portable information terminal held by an operator working in a special environment. The smartphone 20 is paired with the health watch 10 or the like, and can acquire vital data, position information of the health watch 10 or the like, time information, and identification Information (ID) of an operator or the health watch 10 or the like from the health watch 10 or the like via the short-range wireless communication path 15. In addition, the smartphone 20 can be connected to the cloud server 50 via the mobile phone communication network 25. The smartphone 20 can be connected to the communication conversion router 30 via the short-range wireless communication path 26.

When the smartphone 20 can be connected for communication via the mobile phone communication network 25 (that is, when wireless communication is possible between the smartphone 20 itself and the mobile phone base station), the smartphone 20 transmits the vital data acquired from the health watch 10 or the like to the cloud server 50 via the mobile phone communication network 25 (via the mobile phone base station).

On the other hand, when the smartphone 20 cannot perform communication connection via the mobile phone communication network 25 (that is, when wireless communication cannot be performed between the smartphone 20 itself and the mobile phone base station), the vital data acquired from the health watch 10 or the like is transmitted to the communication conversion router 30 via the short-range wireless communication path 26.

At least 1 of the above-described location information, time information, and identification information may be transmitted from the smartphone 20 to the cloud server 50 or the communication conversion router 30 together with the vital data. Note that, in the following, in order to avoid redundant description, it is described that "life data" is transmitted from the smartphone 20 and is collected in the cloud server 50, but this includes not only a case of transmitting only the life data but also a case of transmitting and collecting the life data and at least 1 of the above-described position information, time information, and identification information, and attention is paid to this point.

The mobile phone communication network 25 is a communication network for performing mobile phone communication, and the mobile phone communication referred to herein is wireless communication according to a communication standard such as L TE (L ong Term Evolution) or 3G (3 rd generation mobile communication system).

The short-range wireless communication path 26 is a communication path for performing short-range wireless communication. The short-range wireless communication referred to herein is wireless communication in accordance with a communication standard such as Bluetooth (registered trademark) or Wi-Fi (registered trademark).

The communication conversion router 30 (2 nd relay) can be connected in communication with the smartphone 20 via the short-range wireless communication path 26. The communication conversion router 30 acquires the vital data transmitted from the smartphone 20 via the short-range wireless communication path 26.

In addition, the communication conversion router 30 can be connected in communication with the gateway 40 via the low-power-consumption long-distance wireless communication path 35. The communication conversion router 30 transmits the vital data acquired from the smartphone 20 to the gateway 40 via the low-power-consumption long-distance wireless communication path 35.

That is, the communication conversion router 30 is a vital data relay that transmits vital data acquired by short-range wireless communication through low-power consumption long-range wireless communication.

The low-Power-consumption long-distance wireless communication path 35 is a communication path (L PWAN; L ow Power Wide Area Network) for performing communication for realizing long-distance wireless communication with low Power consumption, and the low-Power-consumption long-distance wireless communication referred to herein is wireless communication conforming to a communication standard such as L oRa (registered trademark), for example.

As illustrated in fig. 1, a worker working in a special environment wears a health watch 10 and a wireless sensor 11, and works while holding a smartphone 20 and a communication conversion router 30.

The gateway 40 can be communicatively connected to the communication conversion router 30 via the low-power-consumption long-distance wireless communication path 35. The gateway 40 acquires the vital data transmitted from the communication conversion router 30 via the low-power-consumption long-distance wireless communication path 35.

In addition, the gateway 40 can be connected in communication with the cloud server 50 via the mobile phone communication network 45. The gateway 40 transmits the vital data acquired from the communication conversion router 30 to the cloud server 50 via the mobile phone communication network 45.

That is, the gateway 40 transmits the vital data acquired by the low-power consumption long-distance wireless communication through the mobile phone communication.

The gateway 40 is provided at a point in the work area where communication connection can be performed via the mobile phone communication network 45 (i.e., a point within the signal range of the mobile phone). The communication conversion router 30 of the operator located at a point outside the signal range of the mobile phone transmits the vital data to the gateway 40 capable of mobile phone communication via the low-power consumption long-distance wireless communication path 35, and transmits the vital data to the cloud server via the gateway 40.

Since the work area is, for example, a wide area of several kilometers to several tens of kilometers in a square circle, and may be several tens of kilometers apart from the distance from the operator to the gateway 40, low-power-consumption long-distance wireless communication such as L oRa (registered trademark) capable of performing communication with low power consumption without using a base station, a repeater, or the like even if several tens of kilometers apart is used as communication between the terminal (communication conversion router 30) held by the operator and the gateway 40.

The mobile phone communication network 45 is a communication network for performing mobile phone communication, and the mobile phone communication here refers to wireless communication according to, for example, L TE or 3G communication standards.

The cloud server 50 acquires the vital data transmitted from the smartphone 20 via the mobile phone communication network 25. Alternatively, the cloud server 50 acquires and manages the vital data transmitted from the gateway 40 via the mobile phone communication network 45.

In addition, the cloud server 50 can be connected to other systems 60 via a communication network 55. The cloud server 50 acquires various data transmitted from the other system 60 via the communication network 55.

The communication network 55 is, for example, the internet, various closed networks (e.g., a private line or a VPN (Virtual private network), or the like), or a combination of these communication networks. The communication network 55 may be a wired communication network, or may be a partially or entirely wireless communication network.

The other systems 60 are, for example, attendance management systems, ERP (enterprise resource planning) systems, weather systems, and the like. In the present description, these systems are collectively referred to as "other system 60".

The cloud server 50 provides various cloud services using vital data acquired from the smartphone 20 or the communication conversion router 30 and various data (for example, attendance management data, ERP data, weather data, and the like) acquired from the other system 60.

The "cloud service" as referred to herein is, for example, a worker health management service and a work process management service provided to a manager who manages a worker working in a special environment. The details of these cloud services will be described later.

[ hardware configuration of communication conversion Router ]

Next, the hardware configuration of the communication conversion router 30 will be described with reference to the drawings.

Fig. 2 is a schematic diagram showing a hardware configuration of the communication conversion router 30 of the vital data collecting system 1 according to the embodiment. As shown in the drawing, the communication conversion router 30 includes a wireless a antenna 301, a wireless B antenna 302, a lithium ion battery 303, and a charging unit 304.

The wireless a antenna 301 is an antenna that transmits and receives radio waves for short-range wireless communication (for example, Bluetooth (registered trademark), Wi-Fi (registered trademark), or the like).

The wireless B antenna 302 is an antenna that transmits and receives radio waves for low-power consumption long-distance wireless communication (for example, L oRa (registered trademark) or the like). furthermore, the wireless a antenna 301 and the wireless B antenna 302 are preferably antennas built into the housing of the communication conversion router 30 so as not to interfere with the work performed by the operator who holds the communication conversion router 30.

The lithium ion battery 303 is a reusable (for example, about 1000 times of charging) secondary battery that can be charged and discharged by moving lithium ions between a positive electrode and a negative electrode. The lithium ion battery 303 is preferably a light-weight and thin lithium ion battery that can be continuously used, for example, within a range of a working time of 1 day (for example, 8 hours) by an operator, and has an overcharge prevention function. Instead of the lithium ion battery, another secondary battery such as a magnesium battery may be used.

The charging unit 304 includes a power supply device (not shown) that generates a dc current for charging from a commercial power supply, and a charge control circuit (not shown) that controls charging of the lithium ion battery 303. The charging unit 304 is configured to be capable of charging by a general charging method similar to that of the smartphone 20, for example, so that the worker can easily perform charging in various environments. The general charging method is a charging method in which ac power is input via a commercial power supply through a commercially available usb (universal serial bus) cable or a commercially available ac (alternating current) adapter, for example.

The communication conversion router 30 is preferably a small-sized (for example, less than 1 cm thick so as to be accommodated in a pocket of the operator) and light-weight (for example, less than 500 g) instrument so as not to hinder the operation by the operator.

The communication conversion router 30 is used in a special environment such as a mine, a mountain area, an ocean, and a construction site, and is preferably configured to have a waterproof function and a dustproof function (for example, to correspond to IP67 defined by IEC (international electrotechnical Commission)). In addition, in the case of being used also in an explosion-proof designated area, the communication conversion router 30 preferably has an explosion-proof function.

Further, for example, the power button of the communication conversion router 30 is preferably disposed at a position on the side surface of the communication conversion router 30 where it is not easily pressed so as not to be accidentally pressed by contact with another object during work, and for example, an L ED (L light emitting diode) lamp for displaying the communication state (or the operation state of the communication conversion router 30) is preferably disposed on the side surface of the communication conversion router 30 so as to allow the worker to easily confirm the communication state during work.

[ functional Structure of communication conversion Router ]

Next, the functional configuration of the communication conversion router 30 will be described with reference to the drawings.

Fig. 3 is a block diagram showing a functional configuration of the communication conversion router 30 of the vital data collecting system 1 according to the embodiment. As shown in the figure, the communication conversion router 30 of the vital data collecting system 1 includes a wireless a antenna 301, a wireless B antenna 302, a wireless a communication unit 305, a wireless B communication unit 306, and a communication conversion unit 307.

The wireless a antenna 301 performs transmission and reception of radio waves for short-range wireless communication based on control performed by the wireless a communication unit 305. As described above, the short-range wireless communication means, for example, Bluetooth (registered trademark), Wi-Fi (registered trademark), or the like.

The wireless B antenna 302 transmits and receives radio waves for low-power-consumption long-distance wireless communication based on control performed by the wireless B communication unit 306. the low-power-consumption long-distance wireless communication may be, for example, L oRa (registered trademark) described above, or the low-power-consumption long-distance wireless communication may be, for example, Sigfox (registered trademark), NB-IoT (narrow band-IoT; narrow band IoT, ZigBee (registered trademark), Z-Wave (registered trademark), or the like.

The wireless a communication unit 305 controls transmission and reception of signals in the short-range wireless communication with the smartphone 20 via the wireless a antenna 301.

The wireless B communication unit 306 controls transmission and reception of signals in the low-power-consumption long-distance wireless communication with the gateway 40 via the wireless B antenna 302.

The communication conversion unit 307 acquires a signal for short-range wireless communication from the wireless a communication unit 305, converts the acquired signal into a signal for low-power consumption long-range wireless communication, and outputs the signal to the wireless B communication unit 306. The communication conversion unit 307 acquires a signal for long-distance wireless communication with low power consumption from the wireless B communication unit 306, converts the acquired signal into a signal for short-range wireless communication, and outputs the signal to the wireless a communication unit 305.

[ procedure for utilizing the worker side ]

Next, an example of a process of using the life data collecting system 1 by the operator will be described.

The worker (or administrator) accesses the cloud service on the cloud server 50 in advance in an environment capable of communicating with the internet, and sets a login ID (Identifier) and a password. The login ID may be, for example, an email address, a telephone number of a mobile phone, or the like.

The worker accesses a website of an os (operating system) provider (e.g., Apple, Google, etc.) or a website of a dedicated application store from the smartphone 20 used for the business. The worker downloads the dedicated application of the cloud service to the smartphone 20 (or acquires the dedicated application transmitted via the mobile device management application software), and installs the dedicated application.

The operator sets the health watch 10 and the smartphone 20 to the pairing mode, respectively. Thus, the health watch 10 and the smartphone 20 can be paired (associated with each other) by wireless communication (for example, Bluetooth (registered trademark)) to transmit and receive data between the health watch 10 and the smartphone 20.

The worker starts the installed dedicated application and registers the dedicated application in the smartphone 20, and for example, by tapping a "device registration button" displayed on the dedicated application, the worker registers the health watch 10 as one of the sensors (sensors to be targets of vital data collection) used in the cloud service. If the registration is made, an email including information such as a use start guide of the cloud service is transmitted to the email address of the worker and the email address of the administrator through the cloud service.

The operator wears the health watch 10 in a state in which the health watch 10 and the smartphone 20 are paired on the wrist, and performs initial setting for making the fall detection function and the abnormality detection function effective in a dedicated application on the smartphone 20. The fall detection function herein refers to a function of detecting that the operator falls by the cloud service, and the abnormality detection function herein refers to a function of detecting that the operator is not moving (no change in movement) by the cloud service. In the initial setting, the acceleration sensor is used to perform the initial setting such that it is determined that the operator has fallen or is abnormal when the angle change from the reference is continued for a certain period of time with the reference being a state in which the operator has hung the wrist in a natural state.

When the operator starts the work in the work area, the operator performs an operation input indicating the start of the work in the health watch 10 (for example, displaying an operation menu on the screen of the health watch 10, operating a button provided on the side surface of the health watch 10, selecting the start of the work from the operation menu, and the like). If an operation input indicating the start of a job is made in the health watch 10, information indicating the start time of the job is transmitted to the cloud service on the cloud server 50 via the smartphone 20.

Further, if an operation input indicating the start of the work is performed, data indicating various measurement values measured by the health watch 10 is transmitted to the cloud service on the cloud server 50 via the smartphone 20 at set intervals (for example, at intervals selected from every 1 second, every 10 seconds, every 30 seconds, every 1 minute, or every 5 minutes, or at every 1 minute if not set). The data indicating various measurement values as used herein refers to vital data such as body temperature, pulse rate, blood pressure, exercise amount, body position, acceleration, and position.

When the operator stops the work in the work area and takes a rest, the operator performs an operation input indicating the start of the rest (for example, displaying an operation menu on the screen of the health watch 10, operating a button provided on the side surface of the health watch 10, selecting the start of the rest from the operation menu, and the like). By this operation, all the life data of the worker (or only specific life data related to privacy such as position information) during the rest period is not collected by the cloud server, and thus the privacy of the worker is protected.

When the operator finishes the rest, the operator performs an operation input indicating the end of the rest (for example, displaying an operation menu on the screen of the health watch 10, operating a button provided on the side surface of the health watch 10, selecting the end of the rest from the operation menu, and the like). By this operation, the collection of vital data by the health watch 10 temporarily stopped is restarted.

When the operator finishes the work in the work area, the operator performs an operation input indicating that the work is finished in the health watch 10 (for example, displaying an operation menu on a screen of the health watch 10, operating a button provided on a side surface of the health watch 10, selecting the work to be finished from the operation menu, and the like). If an operation input indicating the end of the work is made in the health watch 10, information indicating the end time of the work is transmitted to the cloud service on the cloud server 50 via the smartphone 20. Further, even when the operator forgets to perform an operation input indicating the end of the work, the work end time may be registered with the cloud service later.

Further, by performing an operation input indicating the end of the work, the collection of all the vital data of the operator by the health watch 10 at a constant interval is stopped.

In addition, the cloud server 50 may be configured to transmit a message related to weather information to the smartphone 20 of the worker (or to the health watch 10 wirelessly connected via the smartphone 20 of the worker) by cooperating with another system 60 such as a weather system. The weather information-related message referred to herein is, for example, an instruction to the operator such as "there is a possibility of occurrence of thunderstorm after 10 minutes, and therefore, the operation is temporarily interrupted" or a notification message indicating advice information. Further, the cloud service may be configured to transmit a message indicating advice information for presenting replenishment of water and taking a rest to the worker to the smartphone 20 based on weather information and information (for example, information indicating the work start time and the health state) transmitted from the health watch 10 or the like.

[ example of a screen displayed on a smartphone, which utilizes the screen ]

Next, an example of a usage screen of a dedicated application of the cloud service displayed on the smartphone 20 will be described.

Fig. 4A to 4D are schematic diagrams showing an example of a screen displayed on the smartphone 20 of the vital data collecting system 1 according to the embodiment.

A screen sm1 shown in fig. 4A is a device registration screen of the dedicated application displayed on the smartphone 20 at the time of device registration. The worker himself/herself reads the QR code (registered trademark) attached to the health watch 10 (or the QR code (registered trademark) displayed on the screen of the health watch 10) by using the camera of the smartphone 20 used for business. When the QR code (registered trademark) is read, for example, information indicating the target health watch and a "device registration button" are displayed on a screen of the dedicated application, and the worker registers the health watch 10 as one of the sensors used for the cloud service by tapping the device registration button.

As a method of registering the health watch 10 in the cloud service, in addition to the method of registering using the QR code (registered trademark) described above, a method of pairing the smartphone 20 and the health watch 10 by short-range wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark) may be used.

A screen sm2 shown in fig. 4B is a sensor information display screen of the dedicated application displayed on the smartphone 20 when an operation is performed to display information of the sensor that has been registered after the above-described device registration is completed. As shown in the drawing, on the screen sm2, the name and image of the health watch 10 with the device registered described above, and a character indicating that the health watch 10 and the smartphone 20 are in communication connection, "connected" are displayed. On the screen sm2, information indicating the state of the health watch 10 and vital data of the operator, such as "acceleration", "height", "calorie", "moving distance", and "north direction", are displayed. Further, in the upper right area of the screen sm2, an icon image ic1 indicating a setting button is displayed.

The screen sm3 shown in fig. 4C is a setting screen displayed when the region of the icon image ic1 displayed on the screen sm2 shown in fig. 4B is tapped. As shown in the drawing, on a screen sm3, device information indicating the device ID of the above-described device whose registration is completed (i.e., an identifier for identifying the health watch 10 whose device registration is completed) is displayed. As shown in the drawing, on the screen sm3, information indicating the pairing state between the device (health watch 10) corresponding to the device ID indicated by the device information and the smartphone 20 is displayed.

As shown in the drawing, on the screen sm3, sensor information indicating the sensor information acquisition interval and the sensor information transmission interval are displayed, respectively. The sensor information acquisition interval is an interval at which the smartphone 20 periodically acquires, from the sensor, vital data indicating a measurement value measured by the sensor (health watch 10). The sensor information transmission interval is an interval at which the smartphone 20 periodically transmits the vital data acquired from the sensor (health watch 10) to the cloud server 50.

The screen sm4 shown in fig. 4D is a setting screen displayed when the region ar1 displayed as the "sensor information acquisition interval" is tapped in the display region of the "sensor information" in the screen sm3 shown in fig. 4C. This setting screen is a setting screen for the operator to set the interval at which the smartphone 20 acquires the vital data from the sensor (health watch 10). As shown in the drawing, on the screen sm4, a check mark is displayed in the area on the right side of the area displayed as "30 seconds". That is, the smartphone 20 is set to acquire vital data from the sensor at 30-second intervals. The operator can set the sensor information acquisition interval to a desired interval by tapping the regions indicated as "1 second", "10 seconds", "30 seconds", "1 minute", and "5 minutes".

[ example of a screen displayed on a health watch for utilizing a screen ]

Next, an example of the use screen displayed on the health watch 10 will be described.

Fig. 5A to 5D are schematic diagrams showing an example of a screen displayed by the health watch 10 of the vital data collecting system 1 according to the embodiment.

The screen hw1 shown in fig. 5A is a work start confirmation screen displayed on the health watch 10 when the health watch 10 and the smartphone 20 are paired wirelessly. As shown in the drawing, on screen hw1, a "Start job request button is pressed" to prompt confirmation of job Start is displayed for the operator. The operator presses (performs an operation input indicating the start of work) a start button (not shown) provided on the side surface of the health watch 10, for example, to transmit information indicating the start time of work to the cloud service on the cloud server 50 via the smartphone 20, and starts the collection of the regular life data by the health watch 10.

The screen hw2 shown in fig. 5B is a clock screen displayed when the start button (not shown) is pressed (operation input indicating start of operation is performed) when the screen hw1 shown in fig. 5A is displayed. That is, the screen hw2 is a default screen (during the operation time of the operator) when the health watch 10 collects the regular life data. As shown in the drawing, on the screen hw2, in addition to the current time, the date, "Connected" indicating that the health watch 10 has been paired with the smartphone 20, the remaining charge amount of the health watch 10, and the like are displayed.

The screen hw3 shown in fig. 5C is a sensor information display screen displayed when the screen hw2 shown in fig. 5B is displayed, for example, when a start button (not shown) is pressed. As shown in the drawing, on the screen hw3, in addition to information indicating the heart rate measured by the health watch 10 from the operator, "Connected" character indicating that the health watch 10 has been paired with the smartphone 20 is displayed. When the screen hw3 is displayed, the operator presses a Next button (not shown) provided on the side surface of the health watch 10, for example, to switch to display of vital data other than the heart rate (for example, body temperature, blood pressure, and the like).

When the screen hw3 is displayed, the operator presses a Back button (not shown) provided on the side surface of the health watch 10, for example, to return to the display of the screen hw2 (clock screen (default screen)) shown in fig. 5B.

The screen hw4 shown in fig. 5D is a job completion confirmation screen displayed when the screen hw2 shown in fig. 5B is displayed, for example, when a return button (not shown) is pressed. As shown in the drawing, on the screen hw4, an "end job" for prompting confirmation of job end is displayed for the operator. Can? The word "such as" prompts the operator to select either "yes" or "no". When the screen hw4 is displayed, if the operator makes an operation input (operation input indicating the end of work) for selecting "yes", information indicating the end time of work is transmitted to the cloud service on the cloud server 50 via the smartphone 20, and the collection of the periodic vital data by the health watch 10 is ended.

[ example of System manager Screen ]

Next, an example of a system administrator screen provided to an administrator (for example, a site supervisor, a remote administrator, or the like) by a cloud service operating on the cloud server 50 will be described with reference to the drawings.

Fig. 6 and 7 are schematic diagrams showing an example of a system administrator screen generated by the cloud server 50 of the vital data collecting system 1 according to the embodiment.

The system administrator screen cl1 shown in fig. 6 is a work progress management screen referred to by an administrator to confirm the work progress status in each jurisdiction. The system administrator screen cl1 is, for example, a screen (default screen) to be displayed first when an administrator logs in to the cloud service.

As shown in the drawing, the system manager screen cl1 displays information on the progress of work, such as the number of days since the start of a work process, the predicted date of completion of a work process, the work progress rate at the current time, and the number of delay days for a work plan at the current time, for each work site (work area). In the system manager screen cl1, a change to attendance management by the operator, a correction to the work process schedule table, and the like are displayed in accordance with the work progress state.

The system administrator screen cl1 allows the administrator to confirm the work progress status and countermeasures corresponding to the work progress status in each jurisdiction in a list.

The information indicating the work progress status of each of the plurality of jurisdictions and the countermeasures corresponding thereto is generated by the cloud service on the cloud server 50 based on the health status of each worker based on the vital data obtained by the health watch 10 or the like and information obtained from another system 60 such as an attendance management system and a work process management system.

The generation of the information indicating the countermeasure may be realized by, for example, installing an artificial intelligence function in the cloud service.

The system administrator screen cl2 shown in fig. 7 is a monitoring screen referred to by an administrator for monitoring the status of an operator in each jurisdiction. The system manager screen cl2 is displayed, for example, in the system manager screen cl1 shown in fig. 6, by the manager selecting an area displayed as a work area name (for example, "work site a", "work site B", or "work site C") (for example, if the system manager screen is a PC, the mouse is clicked in a state where the cursor cs1 is positioned in the area, or if the system manager screen is a smartphone, the area is tapped).

As shown in the drawing, the system manager screen cl2 displays a map of a work area (for example, the work site a), position information of each worker, weather information such as air temperature and weather, life data (information such as health status) related to each worker, and a KPI (Key Performance Indicator) which is a numerical Indicator to be managed by a manager in service execution.

As shown in the drawing, on the system manager screen cl2, a human-shaped icon image ic2 showing the current position of each operator is displayed on the map of the work area, the position of each icon image ic2 on the map of the work area is updated sequentially as the operator in the actual work area moves, and the position of each icon image ic2 on the map of the work area is updated based on, for example, position information showing the current position measured by a receiver built in the health watch 10 (which may be the smartphone 20) and receiving radio waves of a GNSS (global navigation satellite system) such as GPS and G L ONASS, which is included in life data periodically acquired by the cloud server 50.

On the system manager screen cl2, an icon image ic2 showing the current position of the worker displayed on the map of the work area is displayed in a color changed in accordance with the health status of the worker. For example, an icon image ic2 showing an operator who has no problem such as a health state is displayed by a green human figure, and an icon image ic2 showing an operator who has a problem such as a health state is displayed by a yellow or red human figure according to the degree of the problem based on the conditions described later.

As illustrated in fig. 7, for example, in the system manager screen cl2, if the cursor cs1 is positioned in the vicinity of the area displayed by the icon image ic2 displayed on the map of the job area, a detailed information window image md1 pops up, the detailed information window image md1 showing detailed information on the worker corresponding to the icon image ic 2.

The detailed information window image md1 includes, for example, a facial photograph showing the operator, various vital data (for example, body temperature, pulse rate, heart rate, blood pressure, movement amount, body position, acceleration, and position information), work start time, work end time, and contact information (for example, a telephone number and an email address of the smartphone 20).

The display color of the icon image ic2 is determined in accordance with, for example, the vital data described above. For example, when an operator (hereinafter, referred to as "abnormal operator") is present in any state among a state in which the heart rate is less than 50/min or more than 120/min, a state in which the blood pressure is less than 80mmHg or more than 160mmHg, a state in which the exercise amount (number of steps) exceeds 12000 steps, a state in which the body temperature exceeds 37 degrees, or a state in which the body position is kept "horizontal" and a certain time has elapsed, the display color of the icon image ic2 showing the abnormal operator is displayed in red to call the attention of the manager. The above-described reference value for changing the display color of the icon image ic2 is preferably configured to be arbitrarily set by the administrator.

Further, if an abnormal worker occurs, for example, the cloud service on the cloud server 50 transmits a message indicating that an abnormal worker occurs to an application installed in the smartphone 20 of the administrator, an email address, or the like.

The detailed information window image md1 showing detailed information of an operator corresponding to an abnormal operator includes, for example, a button image (not shown) in which a character such as "know" is described and a button image (not shown) in which a character such as "make a call" is described. When the administrator positions the cursor cs1 near an area where a button image (not shown) in which a character such as "know" is displayed and clicks the mouse, for example, various displays showing an abnormal state are updated to a display showing a normal state. For example, the display color of the icon image ic2 indicating the abnormal worker is updated from red to green.

When the administrator positions the cursor cs1 near the area displayed by the button image (not shown) in which the text such as "call" is described and clicks the mouse, for example, the administrator makes a call to the mobile phone number of the smartphone 20 of the worker. Thus, the manager can immediately contact the worker who is matched with the abnormal worker to check the situation.

Further, if a button image (not shown) in which a character such as "know" is described is clicked or a button image (not shown) in which a character such as "make a call" is described is recorded, the clicked time is recorded in the cloud service as a confirmation time indicating a time at which the administrator confirms the notification of the abnormal state.

As shown in fig. 7, in the left area of the system administrator screen cl2, KPIs, which are numerical indicators to be managed by the administrator in the business execution, are displayed. As shown in the drawing, on the system manager screen cl2, for example, the number of job warnings for each type of job warning generated for the current day is displayed on the circular statistic chart ch 1. As shown in the drawing, the system manager screen cl2 displays, for example, the number of abnormal workers (e.g., the number of absent workers, the number of injured workers, etc.) that have occurred that day.

The system administrator screen cl2 allows the administrator to confirm in real time the status of the operator at each site of jurisdiction, the status of the numerical indicators such as KPIs, and the like.

[ function example for operator ]

The cloud service operating on the cloud server 50 has a function of providing information to the operator, that is, not only information on the status of the operator in the work area and the progress of the work process, but also information on the operator (for example, a site supervisor, a remote administrator, or the like).

For example, the cloud service automatically generates an actual results report indicating information related to health management and attendance management of the worker based on information such as vital data obtained by the vital data collection system 1 every week or every month, and transmits the actual results report to the electronic mail address of the worker. The actual results report may include not only information based on quantitative data such as vital data but also advice information such as an improvement proposal of the work pattern of the field work and social insurance.

The operator can effectively use the information obtained by the actual results report in the human evaluation of the operator or manager, or can effectively use the information obtained by the actual results report when performing a measure of paying compensation to the team in the healthy working environment, or can effectively use the information obtained by the actual results report as information to be provided in response to compliance such as response at the time of external detection.

[ actions of communication converting routers ]

Fig. 8 is a flowchart showing an example of the operation of the communication conversion router 30 of the vital data collecting system 1 according to the embodiment. The flowchart starts when vital data is transmitted from the smartphone 20 to the communication conversion router 30 via the short-range wireless communication path 26.

(step S001) the wireless a communication unit 305 of the communication conversion router 30 acquires vital data from the smartphone 20 via the short-range wireless communication path 26 and the wireless a antenna 301. The wireless a communication unit 305 outputs the acquired vital data based on the signal of the short-range wireless communication to the communication conversion unit 307. Then, the process proceeds to step S002.

(step S002) the communication conversion unit 307 of the communication conversion router 30 acquires the vital data of the signal by the short-range wireless communication outputted from the wireless a communication unit 305. The communication conversion unit 307 converts the acquired vital data based on the signal of the short-range wireless communication into vital data based on the signal of the long-range wireless communication with low power consumption. The communication conversion unit 307 outputs the converted vital data based on the signal of the low-power consumption long-distance wireless communication to the wireless B communication unit 306. Then, the process proceeds to step S003.

(step S003) the wireless B communication unit 306 of the communication conversion router 30 acquires the vital data based on the signal of the low-power consumption long-distance wireless communication output from the communication conversion unit 307. The wireless B communication unit 306 transmits the acquired vital data based on the signal of the low-power-consumption long-distance wireless communication to the gateway 40 via the wireless B antenna 302 and the low-power-consumption long-distance wireless communication path 35.

The process of this flowchart is completed as described above.

< modification of embodiment >

Next, a modified example of the above embodiment will be explained.

In the above-described embodiment, the vital data indicating the measurement value measured by the health watch 10 is transmitted to the cloud server 50 via the smartphone 20 when the mobile phone communication network 25 is available, and is transmitted to the cloud server 50 via the smartphone 20, the communication conversion router 30, and the gateway 40 when the mobile phone communication network 25 is unavailable. With the above configuration, the operator can use the existing (commercially available) smartphone 20, and therefore, the cost of the equipment held by the operator can be reduced.

However, according to the above configuration, the worker needs to perform the work by further holding the smartphone 20 and the communication conversion router 30 after wearing the health watch 10, the wireless mounting sensor 11, and the like. Since the number of devices that the worker has to hold is large, the worker may be hindered from performing the work in some cases. Therefore, for example, the worker may be configured to have a device (hereinafter, referred to as a "repeater") having both the function of the smartphone 20 and the function of the communication conversion router 30, instead of having the smartphone 20 and the communication conversion router 30 separately.

[ operation of repeater ]

Next, the operation of the above-described repeater (not shown) will be described with reference to the drawings.

Fig. 9 is a flowchart showing an example of the operation of the relay in the vital data collecting system according to the embodiment. The flowchart starts when vital data is transmitted from the health watch 10 or the like to a relay (not shown) via the short-range wireless communication path 15.

(step S011) the repeater (not shown) acquires vital data as a signal for short-range wireless communication from the health watch 10 or the like via the short-range wireless communication path 15. Then, the process proceeds to step S012.

When a communication connection to a mobile telephone base station is possible, the repeater (not shown) proceeds to step S013 (step S012). If the communication connection cannot be made (that is, if the communication connection to the mobile phone base station cannot be made), the process proceeds to step S014.

(step S013) the relay (not shown) transmits the vital data acquired in step S011 to the cloud server via the mobile phone communication network 25. The process of this flowchart is completed as described above.

(step S014) the repeater (not shown) converts the vital data of the signal by the short-range wireless communication acquired in step S011 into vital data of the signal by the low-power consumption long-range wireless communication. Then, the process proceeds to step S015.

(step S015) the repeater (not shown) transmits the vital data based on the low-power-consumption long-distance wireless communication signal converted in step S014 to the gateway 40 via the low-power-consumption long-distance wireless communication path 35.

The process of this flowchart is completed as described above.

As described above, the vital data collecting system according to one embodiment is a vital data collecting system for collecting vital data of an actor who acts in a special environment where communication via a mobile phone communication network is difficult, the vital data collecting system including: a relay which is carried by the actor, acquires vital data of the actor measured by a sensor, and transmits the acquired vital data by low-power-consumption long-distance wireless communication; and a collection server that collects the vital data transmitted from the relay.

With the above configuration, the vital data collecting system 1 can transmit data by effectively using a commercially available terminal (for example, a smartphone or a sensor) while suppressing the cost even in a special environment.

In a special environment where a wide operation range is often affected by weather and the like, and in a situation where radio waves of a mobile phone cannot reach, the vital data collection system 1 according to one embodiment can efficiently collect vital data in the cloud server 50 by using the communication conversion router 30 that is inexpensive, portable, and lightweight, reducing the number of relays, and the communication conversion router 30 can acquire vital data from a commercially available smartphone 20 by wireless communication (for example, Bluetooth (registered trademark), Wi-Fi (registered trademark), or the like) that is standard-mounted in the smartphone 20, and convert the vital data to L oRa (registered trademark) that can perform long-distance wireless transmission, and output the vital data.

While one embodiment of the present invention has been described above, the present invention is not limited to this. For example, the present invention is applicable not only to workers who work in a workshop but also to health management, attendance management, and process management of people in other various environments. For example, the present invention can also be applied to surface mining in mines, tunnel work, work on the ocean, mountain climbing, rescue activities, and construction site work.

Further, the vital data collecting system 1 according to the above-described embodiment can be configured by cloud computing, and therefore, it is easy to deal with each work content, and it can flexibly deal with changes in scalability from a small number of people to a large number of people (for example, 1000 or more), and can be introduced with initial investment suppressed. Further, since the vital data collecting system 1 is configured by cloud computing, it is easy to cooperate with other business systems via an api (application programming interface), and it is possible to further improve the efficiency of business.

For example, in a construction site work, a construction work process plan is set in advance, and based on the plan, staff allocation is performed, and it is required to increase efficiency of the overall business including attendance management and the like. According to the life data collecting system 1, for example, an appropriate work can be recommended for an operator by life sensing. Further, according to the vital data collecting system 1, it is possible to provide a proposal for appropriate work process management to a manager, for example, by grasping the health status of the operator. In addition, according to the vital data collecting system 1, for example, for an operator, it is possible to assist compliance measures by appropriate job management of employees and operators of subcontractors.

In the vital data collecting system 1 according to the present invention, the operator can also effectively use the vital data collecting system 1 in the business of providing anonymized vital data to the health care facility manufacturer, the insurance company, or the like for a fee by anonymizing the vital data of the operator. In addition, this enables, for example, manufacturers of healthcare equipment to improve the functions of healthcare equipment, and insurance companies to develop new products for insurance against industrial injuries of workers in special environments.

In addition, a part or all of the vital data collecting system 1 in the above-described embodiment may be implemented by a computer. In this case, a part or all of the program for realizing the control function may be recorded in a computer-readable recording medium, and the program recorded in the recording medium may be read and executed by a computer system.

The "computer system" herein refers to a computer system built in the vital data collecting system 1, and includes hardware such as an OS and peripheral devices. The "computer-readable recording medium" refers to a storage device such as a flexible disk, a magneto-optical disk, a removable medium such as a ROM or a CD-ROM, or a hard disk incorporated in a computer system.

The "computer-readable recording medium" may be a recording medium that dynamically stores a program for a short time, such as a communication line in the case where the program is transmitted via a network such as the internet or a communication line such as a telephone line, or a recording medium that stores a program for a certain time, such as a volatile memory in a computer system serving as a server or a client in this case. The program may be used to realize a part of the above-described functions, or may be further combined with a program that records the above-described functions in a computer system.

In addition, a part or all of the vital data collecting system 1 in the above-described embodiment may be realized as an integrated circuit such as L SI (L area Scale Integration). each functional block of the vital data collecting system 1 may be independently processed, or a part or all of the functional blocks may be integrated and processed, and the method of Integration is not limited to L SI, and may be realized by a dedicated circuit or a general-purpose processor.
