the data identification module is used for identifying the historical overheat protection monitoring data and generating a sample data set triggered by power protection;
The data labeling module is used for labeling the sample data set to obtain a labeled sample data set, wherein the labeled sample data set is a sample data set in an electric shock protection mode;
The feature extraction module is used for extracting features of the labeling sample data set to obtain a false touch feature set;
The triggering acquisition module is used for acquiring a real-time abnormal data set of the first power metering box when the first power metering box triggers an overheat protection instruction;
The false touch probability calculation module is used for establishing a false touch pattern recognition model by the false touch feature set, inputting the real-time abnormal data set into the false touch pattern recognition model to perform false touch probability calculation, and acquiring a first false touch probability;
the early warning information generation module is used for generating first early warning information when the first false touch probability reaches a preset false touch probability.
