Sensor faults mainly include: complete failure, fixed deviation, drift deviation and precision degradation. Failure fault is the sudden failure of sensor measurement, and the measured value is always a constant; Deviation fault mainly refers to a kind of fault that the measured value of sensor is different from the real value by a constant constant. […]
