Anti-external damage intelligent monitoring system and method for power transmission line

Abstract

The invention belongs to an alarm for responding to a specific accident or abnormal condition, and particularly relates to an anti-external damage intelligent monitoring system for a power transmission line, which comprises a warning unit, a video acquisition unit, a data processing unit, a laser detection unit, a power supply control unit and a power supply unit, wherein the power supply unit provides power for the warning unit, the video acquisition unit, the data processing unit and the laser detection unit via the power supply control unit; and the data processing unit is connected with the warning unit, the video acquisition unit and the laser detection unit. The invention also provides an anti-external damage intelligent monitoring method for the power transmission line. Video analysis and laser detection technology are integrated; false and omissive reporting phenomena can be prevented; when a foreign object enters the monitoring area, a warning signal is triggered, whether an external intrusion behavior exits truly is judged again through the video acquisition unit, if the damage behavior truly exists, the warning unit is triggered for warning, and the warning information is transmitted to a monitoring center via the data processing unit.

Description

technical field [0001] The invention belongs to an alarm that responds to a specified accident or abnormal situation, and in particular relates to an intelligent monitoring system and method for preventing external force damage of a transmission line. Background technique [0002] With the rapid development of social economy, urban and rural construction has become more and more frequent. Among them, illegal operations in urban areas, illegal tree planting and house building, and sudden man-made damage have brought great impact on the safe and stable operation of overhead transmission lines. threats and pitfalls. At the same time, because the transmission lines extend tens or even hundreds of kilometers vertically and horizontally, and are located in different environments, it brings great inconvenience to the daily work of operation and maintenance personnel.

Problems solved by technology

At the same time, since the transmission lines extend tens or even hundreds of kilometers vertically and horizontally, and are located in different environments, it brings great inconvenience to the daily work of operation and maintenance personnel.

[0003] In recent years, the behavior of external damage has shown an increasing trend. Both the number of accidents and the degree of harm have greatly increased, which has seriously affected the normal safe and stable operation of the power grid. "The difficulty and cost of handling behaviors are increasing

However, at present, in the work of "anti-breakage", the periodic inspection of the operation and maintenance personnel is mainly used to control the operation status of the transmission line. It is impossible to grasp the external force changes of the line corridor in time, and this method consumes a lot of manpower and material resources, and the operating cost is relatively high

In addition, although a small number of power supply bureaus have installed 3G / 4G video online monitoring systems, the video traffic of the system is difficult to control, so the communication costs are huge, beyond the acceptance range of the bureaus, and manual operations are required, which is difficult to spread in a large area
