Abstract
According to one embodiment, a failure detection apparatus includes processing circuitry. The processing circuitry acquires a time-series signal generated by a sensor module, generates an analysis result including information concerning saturation of the time-series signal by analyzing the time-series signal, and determine a failure of the sensor module based on the analysis result.
Claims10
A failure detection apparatus comprising processing circuitry configured to:
- acquire a time-series signal generated by a sensor module;
- generate an analysis result including information of an amplitude saturation frequency as a frequency with which amplitude values of samples included in the time-series signal are saturated, by analyzing the time-series signal;
- and
- determine that the sensor module is in failure when the amplitude saturation frequency is not less than a predetermined frequency, based on the analysis result.
