MONITORING CONTROL DEVICE AND MONITORING CONTROL METHOD

Title:

MONITORING CONTROL DEVICE AND MONITORING CONTROL METHOD

Document Type and Number:

WIPO Patent Application WO/2021/240191

Kind Code:

A1

Abstract:

This monitoring control device for determining whether there is an abnormality in the detection of the rotation state of a rotating body comprises: a rotation sensor for detecting the rotation state of the rotating body and outputting an analog signal corresponding to the detected rotation state; a converter for, on the basis of the analog signal, calculating a first absolute angle of the rotating body at a first timing and outputting a signal including the first absolute angle; a first control device 10 for acquiring the first absolute angle; and a second control device 20 for, on the basis of the analog signal, calculating a second absolute angle of the rotating body at a second timing different from the first timing. The first control device 10 generates a first diagnosis signal based on the first absolute angle and outputs the first diagnosis signal to the second control device. The second control device generates a second diagnosis signal on the basis of the second absolute angle and determines whether there is an abnormality in the detection of the rotation state by comparing the first diagnosis signal and second diagnosis signal.
