Method for detecting hidden danger in electric transmission line channel

Abstract

The invention discloses a method for detecting a hidden danger in an electric transmission line channel. The method comprises the following steps: an electric transmission line is inspected, and when the hidden danger exists nearby the electric transmission line channel, a first wireless transmission device transmits relevant information of the hidden danger to a terminal device; when receiving the relevant information of the hidden danger, the terminal device conducts a risk assessment according to conditions of the hidden danger, judges the level of the hidden danger according to a risk index obtained through the risk assessment, acquires an electronic map with the hidden danger as the center according to the longitude and latitude of the hidden danger, marks the hidden danger on the electronic map, and displays the relevant information of the hidden danger; when the hidden danger is eliminated, a second wireless transmission device downloads the corresponding hidden danger information from the terminal device according to the longitude and latitude, eliminates the hidden danger, and transmits disposal information of the hidden danger to the terminal device; the terminal device displays the information of the hidden danger and marks the information as being processed, and the process ends. The method enables the hidden danger to be found out in time, makes the information of the hidden danger be displayed on the electronic map in real time, enables the hidden danger to be handled in time, and makes the disposal information of the hidden danger be uploaded in real time, thereby shortening time for hidden danger detection and disposal, being beneficial for guaranteeing safe and reliable operation of a whole grid, improving safety of the electric transmission line, and lowering maintenance cost.

Description

technical field [0001] The invention relates to the field of power transmission lines, in particular to a method for detecting hidden dangers in transmission line channels. Background technique [0002] With the development of the power system, the scale of the power grid is expanding day by day, and the structure of the power grid is becoming more and more complex. As an important part of the power grid structure, the transmission line plays a vital role in the safe and stable operation of the power grid, and because the transmission line is outdoors, it faces complex and changeable environmental conditions, and natural factors and human factors may affect the normal operation of the transmission line. The operation will cause harm, thus affecting the safe and stable operation of the entire power grid. In terms of types, transmission lines can be divided into overhead lines and cable lines. Tree growth, house building, construction, etc. can all threaten the safety of ove...

Problems solved by technology

[0005] The existing detection methods do not further analyze the risks caused by hidden danger information, and lack the investigation of the possibility and severity of hidden danger failures, resulting in insufficient basis for identifying hidden danger levels, which are determined only by the experience of inspectors; in addition, they do not reflect The geographical location of hidden dangers wastes a lot of time and manpower when eliminating hidden dangers; and the existing methods have delays in reporting hidden dangers, making it impossible to eliminate hidden dangers in time, reducing the safety of transmission lines and improving maintenance. cost
