An anti-sabotage early warning system and method for overhead transmission lines

Abstract

The invention discloses an anti-damage early warning system for an overhead transmission line and a method. The system comprises a monitoring background and a front-end monitoring device (1), wherein the front-end monitoring device comprises a binocular camera (6), a radar detection module, a micro processor and a signal emission module, the radar detection module comprises three millimeter wave radar devices with different detection scopes, the monitoring background comprises a signal reception module, a data processing center, an alarm device and a display, the binocular camera (6) and an output end of the radar detection module are respectively connected with the micro processor, an output end of the micro processor is connected with the signal emission module, an output end of the signal emission module is connected with the data processing center through the signal reception module of the monitoring background, and an output end of the data processing center is separately connected with the alarm device and the display. The system is advantaged in that on the basis of combination of the millimeter wave radar detection technology and the depth of field principle of the binocular camera, double detection on an external damage subject matter is realized, and detection and prediction are made to be more accurate.

Description

technical field [0001] The invention relates to an anti-sabotage early warning system and method for overhead transmission lines. Background technique [0002] In recent years, with the development and improvement of the power grid structure, the construction of power lines has made great progress. However, due to the particularity of the geographical location and environmental conditions of the power line, there are many tower points, wide areas, and long lines, and they are exposed to the wild all year round. In addition to being attacked by bad natural weather, human factors, external damage, and anti-theft The probability of line tripping and forced power outage accidents is on the rise, which seriously affects the safety of the power grid. [0003] Discussing and studying countermeasures to prevent power lines from being damaged by external forces and anti-theft, to curb accidents caused by human factors, and to ensure the safe operation of the power grid have become u...

Problems solved by technology

[0004] With the popularization of online monitoring devices for preventing external damage of high-voltage lines, effective monitoring has been played to a certain extent, but the defects of the traditional monitoring mode are becoming more and more obvious; Monitoring personnel are required to manually query a large amount of image and video data to determine whether there is an abnormality on the scene, and the workload is very heavy; secondly, monitoring personnel face boring monitoring images for a long time and cannot concentrate for a long time, resulting in difficulty in the quality of artificial monitoring. However, the traditional high-voltage line anti-external force damage monitoring device can only play the role of post-event tracking; therefore, it is an inevitable development to study a monitoring system with active monitoring, identification and group early warning functions, and to conduct real-time monitoring of external force damage hidden dangers. trend
