STATE DETERMINATION DEVICE, ELEVATOR SYSTEM, HOME SYSTEM, AND BUILDING SYSTEM

WIPO Patent Application WO/2021/001903

A1

Provided are a state determination device, elevator system, home system, and building system that make it possible to more reliably determine the state of a person in a detection area. A Doppler sensor unit (4) detects relative movement between the Doppler sensor unit (4) and a detection object in a detection area. In a state determination device (5) or elevator system (17), an equipment signal acquisition unit (11) acquires a signal from equipment in the detection area upon the movement of the detection object in the detection area. A determination unit (12) determines the state of a person in the detection area on the basis of the relative movement detected by the Doppler sensor unit (4). The determination unit (12) determines that there is an abnormality in the Doppler sensor unit (4) if relative movement between the Doppler sensor unit (4) and detection object was not detected when the equipment signal acquisition unit (11) acquired a signal from the equipment in the detection area upon the movement of the detection object in the detection area.
