Problems solved by technology

And, every time such a sensor is updated, the above man-hours are spent
It should be noted that at this time, if the new sensor cannot be set at the exact position again according to the drawing, the accuracy of determining the position where the abnormality occurs will decrease
Furthermore, if the installation position of the sensor deviates every time the sensor is repeatedly updated, the accuracy of specifying the location where the abnormality occurred will continue to decrease.

[0026] figure 1 It is a figure which shows the outline|summary of the sensor system 1 of 1st Embodiment. Sensing system 1 is a system for maintenance. The sensor system 1 is used in power stations, substations, factories, buildings, transportation facilities, or other facilities. Alternatively, the sensing system 1 can also be used in vehicles such as ships or aircrafts. The sensor system 1 includes a reading device 10 and a plurality of sensor devices 20 .

[0027] The reading device 10 has a function of automatically detecting whether or not abnormal noise is generated by automatically traveling in a facility or the like by using an autopilot. In addition, the reading device 10 has a function of communicating with the sensor device 20 . Furthermore, the reading device 10 has a function of estimating the position of the sensor device 20 . The position of the sensor device 20 is represented by three-dimensional coordinates in a three-dimensional rectangular coordinate sys...

[0112] based on Figure 12 , the sensor system 1b of the second embodiment will be described. Figure 12 It is a block diagram showing the circuit configuration of main parts of the reading device and the server according to the second embodiment. It should be noted that, in Figure 12 , for the first embodiment with the figure 2 The same elements are assigned the same reference signs. In addition, explanations may be omitted for elements that are the same as those in the first embodiment. The sensor system 1b of the second embodiment includes a server 90 in addition to the reading device 10b and the sensor device 20 . The reader 10b and the server 90 are connected to the network NW. The network NW is a communication network including a private network such as an intranet or the Internet.

[0113] The reading device 10 b includes a communication interface 121 and a communication antenna 122 .

[0114] The communication interface 121 is an interface for communicating th...

Abstract

The invention provides a reader device, a sensor device and a sensing system which can lighten sensor setting. The reader device includes a reception unit and a control unit. The reception unit receives sensor data transmitted from a sensor device. The control unit detects an abnormal sound from input sound data. When the control unit detects the abnormal sound, the control unit detects the sensordata including vibration data indicating a correlation with the sound data from which the abnormal sound is detected among the sensor data received by the reception unit. The control unit estimates athree-dimensional position of the sensor device of a transmission source of the detected sensor data.

Description

technical field [0001] Embodiments of the present invention relate to a reading device, a sensor device, and a sensing system. Background technique [0002] In facilities such as substations, when performing maintenance and inspection of equipment and equipment such as power transmission equipment, the person in charge of maintenance and inspection checks for abnormal noise by listening to the sound, and conducts inspections to find abnormalities in equipment and equipment. Thereby, it is also possible to find an abnormality that cannot be found by visual inspection. However, in order to detect abnormalities by listening to the sound in this way, skill is required, so there is a problem that the cost of securing and cultivating human resources is high. In addition, even if the abnormal noise is noticed, there is a problem that it takes time to identify the source of the abnormal noise. [0003] Then, instead of humans, there are cases where a sensor system that detects abn...
