Title:
CLOSED SPACE SENSOR SYSTEM AND OPERATION METHOD OF CLOSED SPACE SENSOR SYSTEM
Document Type and Number:
Japanese Patent JP2022061084
Kind Code:
A
Abstract:
To provide a closed space sensor system for which the stable operation is possible in a closed space.SOLUTION: A closed space sensor system comprises: a power transmission unit 40 of an electromagnetic wave irradiation device 140 which radiates electromagnetic waves; and a plurality of sensors 30A, 30B, 30C... each of which comprises an antenna, and converts the electromagnetic waves received by the antenna into power to be driven. Each of the plurality of sensors comprises a power storage unit, and starts drive when a power storage amount in the power storage unit reaches a drive starting threshold common to the plurality of sensors. In addition, the power transmission unit of the electromagnetic wave irradiation device and the plurality of sensors are arranged in a closed space.SELECTED DRAWING: Figure 1
