Research on Reducing the False Alarm Rate of External Breach Hazards in Online Monitoring System of Transmission Lines

In this paper, through the analysis of the false alarm rate of the transmission online monitoring system, 5 end factors were found and analysed one by one, and finally the 5 end factors of ‘ high percentage of non-sample library machinery ’, ‘ large error of the nearest point of the conductor picture and machinery ’, ‘ large tilt of the clasp ’ were identified, and a countermeasure table of the main causes was formulated by using the ‘ 5W1H method ’, and combined with the previous successful experience, based on the dimensions of the concealed site We established a sample library, constructed a three-dimensional model of the site, calculated the nearest point between the wire and the machinery, and adopted the movable buckle as a countermeasure, successfully reducing the false alarm rate from 75% to 35.78%.
