Abstract

The invention provides a power transmission line crossing point online monitoring and early warning method and system, and the method comprises the steps of carrying out the shooting of two adjacent power transmission lines of the same segment from two visual angles, obtaining video image data, and transmitting the video image data to a monitoring host in real time; enabling the monitoring host to obtain moving image data in the video image data according to the video image data; analyzing the moving image data through a feature comparison method to obtain target model information; comparing the target model information with an alarm threshold value, and generating early warning information according to a comparison result; enabling the monitoring host to upload the early warning information to a cloud storage server in real time, and enabling a remote monitoring center to obtain the early warning information from the cloud storage server in real time. According to the invention, a manual maintenance mode is replaced, the wire spacing can be conveniently and effectively measured, and the working efficiency of power transmission line inspection is improved. Meanwhile, possible risks are avoided in advance, the maintenance frequency of workers can be effectively reduced, and the safety of power grid operation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of crossover point measurement of transmission lines, in particular to an on-line monitoring and early warning method and system for crossover points of transmission lines. Background technique [0002] The safe distance between the conductors of the transmission line is one of the prerequisites for the normal and safe operation of the line. In order to ensure the safe operation of the transmission line, there are different requirements for the safe distance between the conductors of the lines with different voltage levels. Short circuit and other faults. [0003] However, the current cross-over inspection of transmission lines basically relies on traditional manual inspection, which has high work intensity and low efficiency, and manual inspection is prone to misjudgment or missed judgment. Contents of the invention [0004] The purpose of the present invention is to provide a method and system for onlin...
