Line break early warning system

Abstract

The invention relates to a line break early warning system. The early warning system comprises a visual monitoring module, a fiber sensing module, an optical signal acquisition module, a data acquisition and processing module, an indoor monitoring module, an image processing module, a rapid alarm module and a computer, wherein the visual monitoring module comprises a camera and a power supply module, and the inner monitoring module comprises a display screen and an operating console. The early warning system is advantaged in that line break abnormality vibration monitoring is realized, the visual monitoring module can be triggered to carry out real-time shooting, work intensity of line break inspection is substantially reduced, work quality is improved, and relevant inspection management personnel is facilitated to instantly adopt corresponding action; the line break management work level is improved, reliability of power transmission lines is improved, manpower cost is substantially reduced, the concept and the method are provided for line break application demands, and the early warning system is of great importance for safe electric product and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of transmission line monitoring, in particular to an early warning system for line breakage. Background technique [0002] In recent years, as users have higher and higher requirements for power supply reliability, transmission line maintenance has increasingly become one of the mainstream tasks of power supply departments. However, external force damage is the biggest hidden danger affecting the safety of transmission lines. Due to the characteristics of large areas, many points, long lines, and long-term exposure to the wild, transmission lines are more vulnerable to damage. In addition, in recent years, urbanization construction, infrastructure construction, quarrying Human activities such as mining, logging, and road construction are becoming more and more frequent, resulting in repeated damage to transmission lines caused by external force damage, and the frequency of damage shows a trend of frequent oc...

Problems solved by technology

However, this method has disadvantages such as long line inspection cycle, high labor intensity, and difficulty in finding hidden dangers in time.

In this context, video online monitoring technology has been gradually applied in various power grids across the country. Although video monitoring is a mature technology, there are also the following problems: (1) It is necessary for the on-duty personnel to be on duty uninterruptedly, to monitor the computer screen, To find out whether possible external damage factors can be seen in the returned video or photos

(2) Traditional video surveillance devices are only equipped with one camera, and most of them can only shoot live images in one direction, and the actual use effect is not good

(3) The cost of a single device is too high, and there are many line sections that need to be monitored, resulting in many monitoring blind spots

However, the existing manual monitoring methods for hidden dangers such as regular line inspections and special personnel squatting have shortcomings such as long cycle and uncontrollable quality; therefore, it is very necessary to develop a new type of early warning system for line breakage
