Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The structural block diagram of the transmission line anti-external damage online monitoring system is as follows: figure 1 shown. The video monitoring host and the video monitoring extension acquire the on-site video information of the transmission line and preprocess the video information, and the video monitoring extension sends the preprocessed video information to the video monitoring host, and the video monitoring host completes the analysis and diagnosis of the hidden danger of external damage, and the The diagnostic results are reported to the data center station, and at the same time, the early warning command is sent to the video surveillance extension, and the video surveillance extension issues an alarm command to the sound and light alarm extension. The diagnosis result is sent to the monitoring terminal. Since t...

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...
