Title:
CLOSED SPACE SENSOR SYSTEM AND METHOD FOR OPERATING CLOSED SPACE SENSOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/075020
Kind Code:
A1
Abstract:
This closed space sensor system comprises a power transmission unit 40 of an electromagnetic wave emitting device 140 that emits electromagnetic waves, and a plurality of sensors 30A, 30B, 30C, … that are each provided with an antenna, and that convert electromagnetic waves received via the antennas to be driven. Each of the plurality of sensors 30A, 30B, 30C, … is provided with a power storage unit, and when the amount of power stored in the power storage unit reaches a drive start threshold that is common for the plurality of sensors, driving of each of the plurality of sensors may start. The power transmission unit 40 of the electromagnetic wave irradiating device 140 and the plurality of sensors 30A, 30B, 30C, … may be arranged inside a closed space 10.
