Disclosure of Invention

Technical problem to be solved by the invention

In patent document 1, a distribution advertisement capable of adjusting the advertisement display time is used, and usable contents are limited. Furthermore, the time width for adjustment is limited. For example, if an animation is used, it is difficult to greatly change the advertisement display time. For these reasons, the optimum content cannot be used from the viewpoint of the advertising effect. The problem is not limited to the advertisement, and the problem similarly occurs when providing contents to which the passenger is interested, such as for contact and entertainment.

Accordingly, an object of the present invention is to effectively provide passengers with various contents.

Technical scheme for solving technical problem

In order to achieve the above object, one of the operation control system and the operation control method of the present invention is typically: the time required for the elevator car to reach the floor receiving the service request is calculated as the predicted arrival time, the contents are outputted to the passengers at the elevator landing, and the operation of the elevator car is controlled based on the output required time and the predicted arrival time required for the output of the contents so that the output of the contents is completed before the arrival.

Effects of the invention

According to the present invention, it is possible to effectively provide passengers with various contents. Other problems, structures, and effects will be more apparent from the following description of the embodiments.

Detailed Description

The following describes embodiments with reference to the drawings.

[ example 1]

Fig. 1 is a block diagram of an operation control system according to the present invention. As shown in fig. 1, the operation control system includes an operation management device 10, a database 20, an elevation control device 30, an in-car display device 40, a service request device 50, and a landing display device 60.

The elevator control device 30 and the in-car display device 40 are provided in each car of the elevator. The elevation control device 30 is a device that receives an instruction from the operation management device 10 to control the elevation of the car. The in-car display device 40 operates as a car output portion that outputs to passengers by displaying in the car. The in-car display device 40 can display the current place, destination floor, etc. of riding the car. Further, contents such as advertisements may be output to passengers in the riding car.

The service request device 50 and the landing display device 60 are provided at each landing of each floor. Here, the floor refers to a structure in which floors forming a hierarchy are recognized in a building in which an elevator is installed. The elevator car moves vertically on a floor of a hierarchical shape, and the current position and the destination floor at that time are identified by floors. The service requesting device 50 includes a button corresponding to the direction (up direction and/or down direction) of the target layer. The operation of this button is a service request, i.e. a "call", made by the passenger to the elevator. When the acceptance button operation is performed, the service request device 50 notifies the operation management device 10 of the acceptance of the service request. The notification of the service request includes the floor of the hall that received the service request and the direction of the destination floor. In addition, in the configuration using the vertical landing buttons having a button (lower button) of a height at which an operation in a state of sitting on a wheelchair or the like is supposed and a button (upper button) of a height at which an operation in a standing state is supposed, any button is operated, and notification of reception of a service request is included.

The landing display device 60 is a device that operates as a landing output portion that displays an output to a passenger waiting for arrival of a car at a landing of an elevator. The landing display device 60 displays content such as advertisements instructed from the operation management device 10.

The operation management device 10 receives a notification of the service request from the service request device 50, and controls the operation of the car. The operation management device 10 calculates the time required for the car to reach the floor where the service request is received as the predicted arrival time, selects the contents and displays the contents on the landing display device 60, and controls the operation of the car based on the time required for output and the predicted arrival time required for outputting the contents so that the output of the contents is completed before the arrival. The database 20 is a storage device that stores various data used by the operation management device 10.

Fig. 2 is a functional block diagram of an operation control system according to the present invention. As shown in fig. 2, the operation control system includes a car-riding control request unit 11, a content selection unit 14, a prediction unit 15, and a content priority processing unit 16 as functional units, and uses the riding performance data 21, the content data 24, and the like. For example, the operation management device 10 may be configured such that: the functions as the riding car control requesting unit 11, the content selecting unit 14, the predicting unit 15, and the content priority processing unit 16 are realized by executing predetermined programs, and the database 20 may have a configuration in which: the performance data 21 and the content data 24 are stored.

Upon receiving the notification of the service request from the service request device 50, the riding car control request unit 11 assigns an arbitrary riding car to the service request based on the state of each riding car (current location, destination floor, number of passengers, call assignment status, etc.), transmits the lifting request to the lifting control device 30, and controls the operation of the riding car. At this time, the car assigned with the content priority by the content priority processing unit 16 described later is excluded from the assigned objects.

The prediction unit 15 calculates the time required for the car to reach the floor receiving the service request as the predicted arrival time. For example, the arrival prediction time can be calculated with high accuracy by using the riding performance data 21, which is the result of learning the riding performance of each floor, in addition to the state of the car (current position, destination floor, number of passengers, call distribution status, etc.).

The content selection unit 14 selects content corresponding to the predicted arrival time predicted by the prediction unit 15 from the content data 24, and outputs the content by transmitting a content display instruction to the hall display device 60. Since a plurality of contents having different necessary output times are stored in the content data 24, the contents can be output before the arrival of the car by selecting the contents having the necessary output times equal to or less than the predicted arrival time.

The content priority processing section 16 controls the operation of the car based on the output required time and the arrival predicted time so as to complete the output of the content before arrival. Specifically, the content priority processing section 16 designates the car arriving at the landing in accordance with the completion of the content output at the landing as the content priority car, and notifies the car control requesting section 11 of the content priority car. As a result, since the content-priority car is excluded from the objects assigned to the new service request, the deviation between the actual arrival time and the predicted arrival time is suppressed, and the output of the content from the landing display device 60 can be completed at substantially the same timing as when the landing is reached. Further, the exclusion from the assignment target may be performed within a range in which the content is scheduled to travel by the car with priority.

Fig. 3 is an explanatory diagram of learning of the performance of ascending and descending. Fig. 3 shows the learning result of the performance of the ride/descent by the traffic volume in the downward direction and the traffic volume in the upward direction. Specifically, the traffic volume during work is distributed in the region M2 where the traffic volume is small in the downward direction and large in the upward direction. The amount of traffic at lunch is distributed in the area M3 where both the downward direction and the upward direction are large. The traffic volume during the next shift is distributed in the area M4 where the number of traffic volumes is large in the downstream direction and small in the upstream direction. The normal traffic distribution is in the region M1 in which the traffic volume is moderate in both the downstream direction and the upstream direction, and the idle traffic distribution is in the region M0 in which the traffic volume is small in both the downstream direction and the upstream direction.

Fig. 4 is an explanatory diagram of a specific example of the performance of the ascending/descending. Fig. 4 shows the performance of the boarding/alighting from a floor "1 FL" indicating the floor 1, which is the ground floor, to a floor "10 FL" indicating the 10 floors on the uppermost floor. In addition, the case where the destination direction is upward is illustrated as "UP direction (upward direction)", and the case where the destination direction is downward is illustrated as "DOWN direction (downward direction)".

In the performance of riding on and off at work shown in fig. 4, the number of users in the UP direction is generally larger than the number of users in the DOWN direction. Particularly, the number of UP side passengers on the floor "1 FL" is significantly large. Thus, the boarding/alighting performance of each floor shows a characteristic corresponding to the time period. For example, in the first half of lunch, the number of people using in the DOWN direction is generally larger than the number of people using in the UP direction, and the number of people who get off the elevator on the DOWN side of floor "1 FL" and floor "2 FL" increases significantly. In the latter half of lunch, the number of passengers increases on the UP side on floor "1 FL" and floor "2 FL". In addition, the number of people using in the DOWN direction is generally larger than the number of people using in the UP direction at the time of departure from work, and particularly the number of people who get off the elevator at the DOWN side of the floor "1 FL" is significantly increased.

Fig. 5 is an explanatory diagram of the content data 24. In the content data 24, a number No uniquely identifying the content, a name of the content, and a display time are associated correspondingly with data of the content itself, not shown. The display time includes the time required for output, regardless of whether it is a still image or an animation. When the content is an animation, the output required time represents the time required for one play, that is, the length of the animation. When the content is a still image, the output required time indicates the minimum time to be displayed, and if the output required time elapses, the display can be ended at an arbitrary timing.

For example, No "1-1-1-1" is an animated advertisement for a store As, and the time required for playing is 20 seconds. No "1-3-2-1" is a still image advertisement for restaurant Br, and the time required for playing is 15 seconds. Nos "1-4-1-1" to "1-4-5-1" are cases where the office is used as a poster or a bulletin board, and the contents are still images each of which requires 15 seconds of time for output. Nos "2-1-1-1" to "2-1-2-1" are information transmissions from the client, and the contents are moving pictures each of which requires 20 seconds for output. No "3-1-1-1" is set to be sold as an advertisement frame with a CM (commercial message) specified by the purchaser as content. Nos "4-1-1-1" to "4-1-1-2" are contents disclosed on the Internet.

Fig. 6 is an explanatory diagram of the arrival prediction time. In the situation shown in fig. 6, the current landing of the elevator car with car number 1 is 5 floors and a down call has been allocated. Thus, for example, if a downlink call of layer 4 is newly allocated, the arrival prediction time is 5 seconds, and if an uplink call of layer 9 is allocated, the arrival prediction time is 80 seconds. Likewise, car 3 riding machine is currently floor 3 and has been assigned an up call. Thus, for example, if a downlink call of layer 4 is newly allocated, the arrival prediction time is 90 seconds, and if an uplink call of layer 9 is allocated, the arrival prediction time is 50 seconds.

Fig. 7 is a flowchart showing the steps of the operation control. The flowchart is executed by the operation control system from step S101. In step S101 (service request determination), the riding car control requesting unit 11 receives a service request reception notification from the service requesting device 50, determines that a service request has occurred, and proceeds to step S102. In S102 (predicted arrival time calculation), the prediction unit 15 calculates the predicted arrival time at the time of assigning the generated service request for each car based on the state of each car (current position, destination floor, number of passengers, call assignment state, etc.) and the performance data 21 of riding and descending, and proceeds to step S103. In S103 (evaluation calculation), the car control request unit 11 calculates an evaluation value based on an index such as time, traffic jam, and energy saving using the arrival predicted time, and determines a car to be assigned to the service request based on the calculation result. Next, the elevator control device 30 transmits an elevator request to control the operation of the car, and the process proceeds to step S104. In S104 (content selection), the content selection unit 14 selects, from the content data 24, a content whose output required time is equal to or less than the arrival predicted time, using the arrival predicted time predicted by the prediction unit 15, and the process proceeds to step S105. In S105 (content display control), the content selection section 14 performs content display control of transmitting a display instruction regarding the selected content to the hall display device 60, and the process proceeds to step S106. In S106 (content priority control), the content priority processing unit 16 controls the operation of the car based on the output required time and the arrival predicted time so that the output of the content is completed before arrival, and ends the processing.

Fig. 8 is a flowchart showing the detailed processing procedure of the content priority control in S106. The processing step of the content priority control is started by shifting to step S106, and then repeatedly executed until the output of the content is completed. In S201, the content priority processing unit 16 designates a car whose arrival at the landing matches the completion of the output of the content at the landing as a content priority car, and compares the predicted arrival time with the required output time. If the arrival prediction time is not less than the "output required time + α (predetermined allowable error)" (S201; no), the process is directly ended. If the arrival prediction time is less than the "output required time + α (predetermined allowable error)" (S201; yes), the process proceeds to S202. In S202, the content priority processing unit 16 notifies the car control request unit 11 of the car as a content priority car, excludes the car from the objects assigned to the new service request within the predetermined travel range, and ends the processing.

Fig. 9 is a flowchart showing the detailed processing procedure of the content display control in S105. The processing steps of the content display control are started by shifting to step S105, and then repeatedly executed until the output of the content is performed. In S301, the riding car control request unit 11 determines whether or not a call is present within the range in which the riding car travels. If there is a call (S301; No), the process is ended. If there is no call (S301; YES), the process proceeds to S302. In S302, the riding car control requesting unit 11 determines whether the car is traveling. If the vehicle is traveling (S302; YES), the process proceeds to S303, and if the vehicle is not traveling (S302; NO), the process proceeds to S305. In S303, the content selection unit 14 determines whether or not the predicted arrival time is equal to or less than the required output time. If the arrival prediction time is less than the output required time (S303; YES), the process proceeds to S304. If the arrival prediction time is longer than the output required time (S303; NO), the process is ended. In S304, the content selection unit 14 transmits a display instruction for the selected content to the hall display device 60, and ends the processing.

In S305, the content selection unit 14 determines whether or not the predicted arrival time is equal to or less than the required output time. If the arrival prediction time is less than the output required time (S305; YES), the process proceeds to S306. If the arrival prediction time is longer than the output required time (S305; NO), the process proceeds to S308. In S306, the riding car control request unit 11 transmits a lifting request to the car, and the process proceeds to S307. In S307, the content selection unit 14 transmits a display instruction for the selected content to the hall display device 60, and ends the processing. In S308, the riding car control request unit 11 retains the lifting request for the car and ends the processing.

As described above, the operation control system according to embodiment 1 calculates the time required for the car to reach the floor where the service request is received as the predicted arrival time, outputs the contents to the passenger at the elevator landing, and controls the operation of the car so that the contents are output before the arrival, based on the time required for the output of the contents and the predicted arrival time.

By preferentially outputting the contents to control the operation of the car in this manner, it is possible to select the optimum contents from arbitrary contents including moving pictures and match the end of the contents with the arrival timing of the car, thereby effectively providing various contents to passengers.

In addition, the operation control system according to embodiment 1 can select a content that can effectively use the arrival prediction time by preparing a plurality of contents having different times required for output in advance and selecting a content according to the arrival prediction time.

In addition, the operation control system according to embodiment 1 excludes the car as the riding car with priority given to the content from the objects assigned to the new service request, with respect to the riding car that controls the operation to complete the output of the content. For example, by excluding the car from the objects assigned to the new service request within the predetermined travel range, the content-priority car can suppress the deviation between the actual arrival time and the predicted arrival time, and can complete the content output at substantially the same timing as the arrival at the hall.

Further, the operation control system according to embodiment 1 can accurately predict the arrival prediction time by calculating the arrival prediction time using the result of learning the boarding/alighting performance for each floor.

Further, the operation control system according to embodiment 1 starts outputting the contents so that the time point when the outputting of the contents is completed coincides with the time point when the car arrives. That is, when the time required for output is shorter than the arrival prediction time, the start of output is delayed. Since the pressure of the waiting time at the landing gradually increases, when the output of the content is performed immediately before the arrival, the pressure reduction effect by the content increases. In addition, as the number of waiting people in the hall is gradually increased, the output starting delay can provide contents for more passengers, and the advertising effect is also larger.

[ example 2]

In embodiment 2, the operation control system predicts the riding time of the riding car and controls the output of the contents of the riding car in addition to the configuration and operation of embodiment 1. Therefore, descriptions of the configuration and operation common to those of embodiment 1 are omitted, and the points of change will be described.

Fig. 10 is a flowchart showing the procedure of the operation control of embodiment 2. The flowchart is executed by the operation control system from step S401. In step S401 (service request determination), the riding car control requesting unit 11 receives a service request reception notification from the service requesting device 50, determines that a service request has occurred, and proceeds to step S102. Here, in embodiment 2, the service request includes the specification of the target layer. That is, a target floor reservation system is employed, which inputs a target floor desired by the passenger at a point of time when the service request device 50 is operated. In S402 (predicted arrival time calculation), the prediction unit 15 calculates the predicted arrival time at the time of assigning the generated service request for each car based on the state of each car (current position, destination floor, number of passengers, call assignment state, etc.) and the performance data 21 of riding and descending, and proceeds to step S403. In S403 (predicted riding time calculation), the prediction unit 15 calculates a time until the passenger riding in the car gets off the elevator at the destination floor as a predicted riding time, and the process proceeds to step S404. The predicted riding time can be calculated using the specified destination floor in addition to the state of each riding car (current location, destination floor, number of passengers, call assignment condition, etc.) and the riding performance data 21. In S404 (evaluation calculation), the car control request unit 11 calculates an evaluation value based on an index such as time, traffic jam, and energy saving using the arrival prediction time and the target floor, and determines a car to be assigned to the service request based on the calculation result. Next, the elevator control device 30 transmits an elevator request to control the operation of the car, and the process proceeds to step S405. In S405 (content selection), the content selection unit 14 selects the content to be displayed on the hall display device 60 and the content to be displayed on the in-car display device 40, and the process proceeds to step S406. The contents displayed on the landing display device 60 are selected in the same manner as in embodiment 1. The contents displayed on the in-car display device 40 are selected from the contents data 24 so that the output required time is equal to or less than the predicted riding time, using the predicted riding time predicted by the prediction unit 15. In S406 (content display control), the content selection unit 14 performs content display control for transmitting a display instruction regarding the selected content to the hall display device 60 and the in-car display device 40, and the process proceeds to step S407. In S407 (content priority control), the content priority processing unit 16 controls the operation of the car so that the output of the content is completed before the arrival, based on the output required time, the arrival predicted time, and the predicted riding time, and ends the processing.

Fig. 11 is a flowchart showing a detailed processing procedure of the content display control in the riding car. The processing steps of the content display control are started by shifting to S406 and then repeatedly executed until the output of the content is performed. In S501, the content selection unit 14 determines whether or not a content to be displayed in the range in which the car is traveling is selected. If selected (S501; No), the process proceeds to S502. If not (S501; NO), the process proceeds to S506. In S502, the content priority processing unit 16 compares the predicted riding time with the output required time. If the predicted riding time is not less than the "output required time + α (predetermined permissible error)" (S502; no), the routine proceeds to S505. If the predicted riding time is less than the "required output time + α (predetermined permissible error)" (S502; yes), the routine proceeds to S503. In S503, the content priority processing unit 16 notifies the car control requesting unit 11 of the car as the content priority car, excludes the car from the objects assigned to the new service request within the predetermined travel range, and the process proceeds to S504. In S504, the content selection unit 14 transmits a display instruction regarding the selected content to the in-car display device 40, and ends the process. In S505, the content selection unit 14 displays a default screen on the in-car display device 40, and ends the process.

In S506, the content selection unit 14 determines whether or not the stop layer is increased. If the stop layer is not added (S506; NO), the process is ended. If the stop layer is increased (S506; YES), the process proceeds to S507. In S507, the content selection unit 14 selects the increased content as the case may be, for the scheduled travel range changed by the increase of the stop floor, and ends the process.

As described above, the operation control system according to embodiment 2 receives the service request and also receives the designation of the destination floor, calculates the riding time of the riding car, and outputs the contents corresponding to the riding time to the passenger in the riding car.

Therefore, the operation control system according to embodiment 2 can effectively provide various contents to passengers riding in the car, in addition to the same effects as embodiment 1.

Further, the contents outputted from the hall and the contents outputted from the car may be linked. For example, a continuation of the content output at the landing may be output within the riding car. In this case, the predicted arrival time at the hall may be added to the predicted riding time calculated before riding by the designation of the target floor, and the content whose output required time is shorter than the added time may be selected.

In the above-described embodiment, the case where the output of the content is started so that the output of the content is completed in accordance with the arrival of the car is described as an example, but the start of the output of the content may be determined by other conditions. For example, the call may be made at a time point, or the call assigned to the number may be made at a time point when the call is not made. Further, the time point when there is no person in the car, the time point when the number of waiting persons in the hall reaches a certain number or more, or the time point when the number of waiting persons reaches half of the estimated number of waiting persons in the arrival prediction time, or the like may be used.

In the above-described embodiment, the case where the content is selected based on the arrival prediction time has been described as an example, but the content may be selected by using a factor other than the arrival prediction time. Fig. 12 is a flowchart showing a processing procedure in a modification of content selection. In S601 (arrival predicted time acquisition), the content selection unit 14 acquires the arrival predicted time from the prediction unit 15, and the process proceeds to step S602. In S602 (candidate content extraction), the content selection unit 14 extracts, as candidate content, content whose output required time is equal to or less than the arrival prediction time, and the process proceeds to step S603. In S603 (constraint condition acquisition), the content selection unit 14 acquires a condition usable for constraint of the content, and the process proceeds to step S604. As the limiting condition, the estimation result of the attribute of the passenger, the estimation result of the target floor, or the like may be used. In S604 (content determination), the content selection unit 14 determines the content by defining candidate contents under the constraint condition. Therefore, by selecting the content suitable for the attribute of the passenger and the target floor using the attribute of the passenger and the estimation result of the target floor, it is possible to further provide effective content.

The present invention is not limited to the above-described embodiments, and various modifications are also included. For example, the above-described embodiments are described in detail to facilitate understanding of the present invention, and are not limited to having all the structures described. In addition, not only the related structure may be deleted, but also the structure may be replaced or added.
