  • FAULT DETECTION METHOD FOR DETECTING BEHAVIOR DEVIATION OF PARAMETERS
    Publication number: 20240176335
    Abstract: A fault detection method, includes the following steps. A target sequence is received, the target sequence includes several data. A first moving average operation is performed on the target sequence to establish a first moving average sequence. A second moving average operation is performed on the target sequence to establish a second moving average sequence. A difference operation between the first moving average sequence and the second moving average sequence is performed to obtain a difference sequence, the difference sequence includes several difference values. An upper limit value is set. When one of the difference values is greater than the upper limit value, the target sequence is determines as abnormal.
