the monitoring platform is used for establishing a line operation digital twin monitoring system according to the operation electrical parameters, the environmental parameters, the infrared temperature measurement images and the three-dimensional model of the line to monitor the safe operation of the line;
the monitoring platform comprises an electric leakage abnormity monitoring strategy, wherein the electric leakage abnormity monitoring strategy comprises the steps of positioning a position with higher temperature and marking a corresponding abnormal position on the three-dimensional model when the calculated temperature difference value of different sections on the same operation line is greater than a first threshold value, and simultaneously recording corresponding first temperature abnormity information;
the leakage abnormity monitoring strategy also comprises a first highest allowable operation electrical parameter of an abnormal position is set according to the temperature difference value, and overload early warning is carried out when the operation electrical parameter is greater than the first highest allowable operation electrical parameter.
