Technical Field

The present invention relates to a sensor device according to the preamble of claim 1.

Background

During assembly of components, machines, and systems, many activities are performed manually. Examples are the positioning and fastening of the parts and the manufacture of the plug connection. In practice, it has been found that the manual manufacture of the plug connection is particularly prone to errors. It is therefore necessary to check each manually manufactured plug connection, which leads to a high amount of labour in the context of quality assurance.

Disclosure of Invention

It is therefore an object of the present invention to provide a sensor device which enables monitoring of manual activities in the case of manual assembly.

To achieve this object, a sensor device having the features of claim 1 is provided.

The sensor device according to the invention comprises a solid-borne sound sensor (sensor) which is detachably attachable to an installation location on the body of a user and which is capable of detecting solid-borne sound generated by the user by means of manual activity in the form of a sensor signal. The sensor device comprises a controller connected to the solid-borne sound sensor and designed to evaluate a sensor signal of the solid-borne sound sensor, the controller being able to determine, based on the evaluated sensor signal, whether the solid-borne sound generated by the artificial activity is sufficient to correspond to the stored solid-borne sound profile. The sensor device according to the invention is characterized in that the solid-state sound sensor is adapted to detect solid-state sound generated by artificial activities of the user and transmitted substantially in the body of the user via the skeleton, i.e. via the bones and/or tendons, to the fastening location.

The term "solid-state acoustic sensor" will be understood in a general sense. It can be, for example, a piezoelectric sensor. The solid-state acoustic sensor can be combined with a gyroscope sensor and/or a position sensor.

The controller serves as an evaluation device which is designed for the preliminary filtering and/or evaluation of the sensor signal of the solid-state sound sensor.

The present invention is based on the consideration of generating solid noise that is transferred to the user's hand and fingers during the performance of manual activities, especially during assembly activities. The solid sound is transmitted via the skeleton of the user's body (i.e., via the bones and/or tendons). By recording the solid-borne sound by means of the solid-borne sound sensor and subsequent evaluation, it can be assessed whether the solid-borne sound corresponds to a known and/or stored solid-borne sound profile. Certain standard activities within the scope of assembly (e.g., manufacture of plug connectors) are characterized by the creation of a characteristic solid-state sound profile. By comparing the known solid noise profile with the currently recorded sensor signal, it can thus be assessed whether the performed manual activity was performed correctly or was erroneous.

An advantage of the sensor device according to the invention is that the solid state acoustic sensor does not require a finger attached to the hand of the user. Since solid sounds are transmitted via a skeleton in the user's body (i.e., via bones and/or tendons), it is sufficient to removably attach the sensor assembly to any suitable mounting location on the user's body. For example, the sensor array can be attached to the upper arm by straps. Alternatively, it is also possible to attach the sensor array to the user's belt, for example. The sensor array can also be integrated into an article of clothing. Thus, the sensor array can be attached to almost any position of the user's body. Since the resulting solid-state noise becomes weak as the distance from the place where the sound is generated increases (i.e., as the distance from the user's hand increases), an installation position that enables sufficiently safe detection of the solid-state noise is preferable.

Alternatively, the sensor assembly can be attached to the tool or the mounting bracket. The solid state sound is then transmitted from the tool or mounting bracket to the solid state sound sensor via the user's skeleton.

Further, the invention relates to the use of a sensor device according to the invention for detecting solid-state sounds, which are generated by artificial activities of a user and are essentially transferred to a fastening location via a skeleton in the body of the user (i.e. via bones and/or tendons). By means of the sensor device according to the invention, it is thus possible to detect and evaluate solid-borne sounds generated during manual activities.

In addition, the invention relates to a method for detecting solid-borne sound, having the following steps: attaching a solid-state sound sensor to an attachment location on the body of a user or on an article of clothing, the solid-state sound sensor being connected to a controller, the controller being designed to evaluate a sensor signal of the solid-state sound sensor, detect by the solid-state sound sensor solid-state sound generated by artificial activity of the user, the solid-state sound being transmitted to the fastening location via a skeleton in the body of the user (i.e. via a bone and/or tendon), determine by the sensor signal evaluated by the controller whether the solid-state sound generated by artificial activity is sufficient to correspond to a stored solid-state sound, the solid-state sound sensor detecting solid-state sound, the solid-state sound being generated by artificial activity of the user and being substantially transmitted to the fastening location via the skeleton in the body of the user (i.e. via a bone and/or tendon).

Drawings

The invention is explained below by way of example with reference to the accompanying drawings. The figures are schematic representations and show embodiments of the sensor device according to the invention.

Detailed Description

The sensor device 1 shown in the individual figures is designed so-called "wearable", in this embodiment in the form of a bracelet or bracelet. However, this design is to be understood as an example only.

During manual activities, for example when assembling a plug connection, a solid sound is generated which is transmitted to the hand 2 of the user. From there, solid sound is transmitted via the skeleton of the user's body, i.e. via the bones and/or tendons, and/or the skin, to the mounting location of the sensor array 1. The sensor array may be attached to the user's forearm, upper wall, belt, or integrated into the user's clothing.

The sensor device 1 comprises a schematic representation of a solid-state acoustic sensor 3, the solid-state acoustic sensor 3 being characterized by a high sensitivity and being capable of detecting solid-state sounds of low intensity.

The sensor device 1 is equipped with communication means enabling wireless transmission via a radio protocol. The transmission takes place, for example, via a Wireless Local Area Network (WLAN), via bluetooth or other radio transmission methods. Information exchange with other mobile or fixed devices is enabled by the communication device.

Alternatively or additionally, the sensor array 1 can also be connected via a cable 4 to a mobile device 5, such as a personal computer, or a stationary device 6. The mobile device 5 can be a single board computer, an embedded personal computer, or a conventional mobile device such as a smartphone or tablet. The stationary device can be a personal computer, a remote computer located at a data center, or a computer connected via the internet. The mobile device 5 also comprises communication means for wireless communication. The sensor array 1 can also be connected to a stationary computer 6 via a wireless communication link, e.g. a cellular network. The sensor array 1 according to the invention is also suitable for detecting solid-state noise generated during operation of a machine or device. Solid-borne sound is transmitted via mechanical structures such as machine housings. Thus, it is also possible to monitor a machine, such as a robot arm or a robot, by means of the sensor device according to the invention. Since different tools produce different solid-state sound profiles, by detecting the solid-state sound, it can be determined whether the robot has gripped a certain tool, for example.

Furthermore, the sensor device with its respective components enables different optional variations and additional developments:

according to one variant, the sensor device comprises a sensor (solid-state acoustic sensor), an amplifier, a battery and a cable connection.

According to another variant, the sensor device comprises a solid-state acoustic sensor, an amplifier and a cable connection.

According to another variant, the sensor device comprises a solid-state acoustic sensor, an amplifier, an a/D converter, a battery and a cable connection.

According to another variant, the sensor device comprises a sensor, an amplifier, an a/D converter and a cable connection.

According to another variant, the sensor device comprises a solid-state acoustic sensor, an amplifier, an a/D converter, a battery and a radio module acting as a communication device.

According to another variant, the sensor device comprises a sensor, an amplifier, an a/D converter, a cable connection or a cable and a radio module.

According to another variant, the sensor device comprises a sensor, an amplifier, an a/D converter, an RFID transponder for Near Field Communication (NFC), a battery and a radio module.

According to another variant, the sensor device comprises a sensor, an amplifier, an a/D converter, an RFID transponder and a cable.

According to another variant, the sensor device comprises a sensor, an amplifier, an a/D converter, an RFID transponder for near field communication, a controller, a battery and a radio module.

According to another variant, the sensor device comprises a sensor, an amplifier, an a/D converter, a near field communication RFID transponder, a controller and a cable.

The sensors can consist of solid-state acoustic sensors and/or gyroscope sensors (acceleration sensors) and/or position sensors.

With the sensor arrangement according to the invention, the signal is acquired by a sensor, in particular by a solid-state acoustic sensor. Alternatively, the signal processing can also be performed directly by the sensor device. Alternatively, the analog and/or digital sensor signals can be transferred wirelessly to the mobile device 5, either via the cable 4 shown in the figure or by communication means to the stationary computer 6. The sensor array 1 can also be supplied with electrical energy via the cable 4. After evaluation of the sensor signals, for example by means of the mobile device 5 or by means of the stationary computer 6, feedback is sent back to the sensor array 1, so that signals can be output therefrom for the user. The signal can be an optical signal and/or an acoustic signal and/or a tactile signal. A feedback signal is output to inform the user that the installation procedure has been performed correctly or incorrectly. For example, if the connector is found to be improperly installed, some audible or visual signal can be output even if the signals are different from the signals for proper installation. It is also possible to signal only in the event of an error (i.e. if an incorrect plug connection is detected or the like).

All described variations and combinations of features can also be combined with one another or individual features can be omitted.
