WIPO Patent Application WO/2024/084790
Kind Code:
A1
Abstract:
Provided are a moving body state monitoring device, a moving body state monitoring method, and a moving body state monitoring program with which an abnormality of a movement path of a moving body and of the moving body can be detected accurately. A moving body state monitoring device according to the present disclosure determines an abnormality of at least one of a movement path of a moving body that includes a magnetic geared motor, the magnetic geared motor and the moving body, the moving body state monitoring device comprising: a phase angle acquiring unit for acquiring a phase angle of a low-speed rotor of the magnetic geared motor, and a phase angle of a high-speed rotor of the magnetic geared motor; and an abnormality determining unit for determining an abnormality of at least one of the movement path of the moving body, the magnetic geared motor and the moving body, on the basis of a phase difference integral value representing an integral value of a difference between a phase difference between the low-speed rotor and the high-speed rotor estimated on the basis of an input power, and the phase difference between the low-speed rotor and the high-speed rotor acquired by the phase angle acquiring unit.
