Title:
SENSOR DEVICE, MANAGEMENT SYSTEM, MANAGEMENT SERVER, ACCEPTANCE INSPECTING DEVICE, METHOD EXECUTED BY SENSOR DEVICE, AND NOMENCLATURE PLATE
Document Type and Number:
WIPO Patent Application WO/2021/065925
Kind Code:
A1
Abstract:
Sensor devices (10) are attached to various products. Each sensor device (10) is provided with a sensor unit (12), a communication unit (200), a storage unit (18), an electricity storage unit (24), and an environmental electricity generating unit (22). The sensor unit (12) measures a state relating to the product. The communication unit (200) outputs information based on the measurement result obtained by the sensor unit (12). The storage unit (18) stores the measurement result obtained by the sensor unit (12), and the information output from the communication unit (200). The electricity storage unit (24) supplies electric power for operating at least one of the sensor unit (12), the communication unit (200), and the storage unit (18). The environmental electricity generating unit (22) converts external environmental energy into electric power to charge the electricity storage unit (24). In the sensor device (10), at least two of the sensor unit (12), the output unit (16), and the environmental electricity generating unit (22) are arranged overlapping one another. As a result, the size of the sensor device (10) can be reduced, making it easy to attach the sensor device (10) to a target object.
