Anomaly detection method, anomaly detection system, sensor and electronic device

Abstract

Provided is an anomaly detection method for detecting an anomaly of a plurality of sensors, each packaged separately, using a plurality of comparators, the plurality of sensors respectively having a sensor element for detecting current or magnetism, a signal processing circuit for processing the detection signal from the sensor element, and an input terminal into which the detection signal from another sensor among the plurality of sensors is input, the plurality of comparator each corresponding to the plurality of sensors, comparing the detection signal output from a signal processing circuit of the corresponding sensor to a detection signal from another sensor, the method including comparing the detection signal from the corresponding sensor to the detection signal from another sensor and outputting an anomaly signal when the comparison result between the detection signal from the correspond sensor and the detection signal from another sensor does not meet a predetermined standard.

Dependencies are inferred from the claim text.
