Transmission line damage prevention early warning system based on multi-sensor fusion technology

Abstract

The invention relates to a transmission line damage prevention early warning system based on the multi-sensor fusion technology and belongs to the power grid protection technology field. The early warning system comprises an onsite power source unit, an information acquisition unit, an alarm unit and a main server used for carrying out remote operation, wherein the main server realizes remote information transmission with the information acquisition unit and the alarm unit through the wireless network, the information acquisition unit comprises a laser detector and a video monitor on a pole and a supersonic wave detector hung and fixed on a transmission line, and the alarm unit comprises a high pitch alarm device on the pole and a sound-light alarm device on the transmission line. According to the early warning system, integrated information acquisition is carried out by utilizing multiple types of sensors, accuracy for information acquisition of objects entering a dangerous zone is greatly improved, dangers are eliminated before generation, and effective early warning and driving effects for the objects entering the dangerous zone are realized.

Description

technical field [0001] The invention belongs to the technical field of power grid protection, and in particular relates to a power line anti-sabotage early warning system based on multi-sensor fusion technology. Background technique [0002] With the rapid development of the national economy and the continuous expansion of the city, the transmission lines are becoming more and more dense, and the operating environment is becoming more and more complex. Many transmission lines span roads, railways, bridges, rivers, lakes, mountains, buildings, etc. The safety of the environment is increasingly threatened by various illegal constructions, illegal buildings, illegal trees, floating objects and bird damage. [0003] Accidents of power transmission lines being damaged by external forces occur from time to time all over the country. For example, the construction site is under or near the power transmission line, and construction equipment (mainly cranes, excavators, concrete mixer...

AI Technical Summary

Problems solved by technology

[0005] The invention solves the disadvantage that the existing transmission lines cannot eliminate potential threats, and provides a transmission line anti-sabotage early warning system based on multi-sensor fusion technology. The early warning system uses a variety of sensors to provide early warning of potential threats and sends alarm information to control the alarm , the alarm unit eliminates risk factors before damage occurs, multiple sensors assist each other, complement each other, and integrate each other, with high detection accuracy and low threat omission rate, which can effectively prevent external force damage early warning
