Distributed power transmission line outside force destroy proofing on-line monitoring system and monitoring method

Abstract

The invention relates to a distributed power transmission line outside force destroy proofing on-line monitoring system and monitoring method. The method includes a video monitoring host, a video monitoring subunit, an acousto-optic alarm subunit, a data center station and a monitoring terminal, the video monitoring host and the video monitoring subunit are arranged at the two ends of a power transmission line tower cross arm, and the acousto-optic alarm subunit is distributed on the power transmission lead. The invention creatively proposes a time synchronous double-video monitoring manner, the detection range is wide, a coordinate system is established based on the geographical position information of the transmission tower and the transmission conductor, the fault hidden trouble diagnosis of a moving object in the monitoring area can be completed in the video monitoring host, and a lot of video information is not needed to be uploaded to the data center station, so that the data communication fee is saved, the system power consumption is reduced, preventive measures are taken for the power transmission line outside force destroy faults, and the stable operation level of the power grid is improved.

Description

technical field [0001] The invention relates to the related technical field of on-line monitoring of transmission lines, in particular to a distributed on-line monitoring system and method for preventing external force damage of transmission lines, which are mainly used in monitoring, diagnosis and early warning of external force damage activities of transmission lines. Background technique [0002] Since the transmission line has the characteristics of a large area span, complex surrounding terrain conditions, and a large impact on the environment and climate, it is extremely vulnerable to damage by external forces. At present, the common causes of external force damage to power facilities mainly include illegal construction, illegal buildings, vegetation, floating objects, wildfires, and bird damage. In recent years, with the increase of engineering construction, large-scale mechanical construction under the transmission line, tower crane collision line, tree collision lin...

Problems solved by technology

[0004] In order to solve the problems of narrow detection range, high false alarm rate, weak warning function, unreliable system power supply and other problems existing in the monitoring means of preventing external force damage of transmission lines in the prior art, a distributed online monitoring system for preventing external force damage of transmission lines is proposed and The monitoring method is to obtain the three-dimensional information of the line and the surrounding environment by installing time-synchronized dual cameras on the transmission line tower, and can calculate the distance between the construction machinery and the tower, as well as the distance between the construction machinery and the line; at the same time, install sound and light alarms on the transmission line distribution After discovering hidden troubles, it can realize the alarm nearby. The invention can greatly improve the warning effect of external force damage early warning, and effectively prevent the occurrence of external damage accidents.
