The invention belongs to the technical field of equipment fault monitoring, and relates to a CPB threshold value setting method and system based on AI assistance. The method comprises the following steps: acquiring first sensor monitoring data of a sample product, and constructing a label matrix for identifying the running state of the product; calculating an energy value of the first sensor monitoring data on each CPB frequency band to obtain an energy matrix; constructing a CPB frequency band energy feature vector based on the energy matrix and the label matrix; acquiring second sensor monitoring data of the to-be-tested product, and calculating energy distribution of the second sensor monitoring data on each CPB frequency band to acquire a feature vector corresponding to the second sensor monitoring data; and comparing the feature vector corresponding to the monitoring data of the second sensor with the constructed CPB frequency band energy feature vector so as to judge the current running state category o
