Document Type and Number:
WIPO Patent Application WO/2024/019005
Kind Code:
A1
Abstract:
A sensor unit (30) of a sensor device (1) comprises detection elements (31-33), a power supply failure determination circuit (355), and a sensor-side communication unit (359), wherein at least a portion of operations can be continued by feeding from a battery feeder (Lb) even while a starting switch (901) is turned off. A control unit (60) includes a control unit-side communication unit (69), a control calculation unit (65), and a non-volatile memory (67), and operates by means of power supplied via the starting switch (901). The control unit (60) acquires, from the sensor unit (30), power supply failure information while the starting switch (901) is turned off, and transmits a return signal to the sensor unit (30) after the power supply failure information is stored in the non-volatile memory (67).
