Protection switching method for high-voltage circuit signal monitoring

The invention provides a protection switching method for high-voltage circuit signal monitoring, and relates to the technical field of abnormal protection, and the method comprises the steps: firstly building a basic feature set of a power transmission line, then carrying out the line segmentation, generating a segmentation identifier, building a signal risk data set, and generating an abnormal signal recognition network, and then configuring a monitoring node to generate real-time monitoring data, inputting the real-time monitoring data into an anomaly recognition network to obtain an anomaly monitoring result, performing auxiliary recognition in combination with the unmanned aerial vehicle, and finally judging a compensation result activation protection mode for the anomaly recognition result. The problems that in the prior art, the cost is high, a circuit cannot be monitored in real time, protection measures cannot be taken in real time, the monitoring risk is high, and the monitoring accuracy is low are m
