Electric transmission line tower displacement monitoring system and method

Abstract

The present invention relates to an electric transmission line tower displacement monitoring system and method. The system comprises a monitoring base station, a monitoring terminal and a monitoring server; the monitoring base station is a Beidou navigation satellite system base station; the monitoring terminal is installed on an electric transmission tower and comprises a Beidou location chip; the monitoring base station is connected with the monitoring terminal to send geographical coordinates of the monitoring base station; the monitoring terminal receives the geographical coordinates of the monitoring base station and obtain posture information of the electric transmission line tower through adoption of the carrier phase difference technology; the monitoring terminal is connected withthe monitoring server to send the posture information of the electric transmission line tower; and the monitoring server receives the posture information of the electric transmission line tower and compares with preset posture information for monitoring. The electric transmission line tower displacement monitoring system and method can effectively improve the operation reliability of power grid, reduce the operation cost and greatly reduce the work intensity of operation and maintenance personnel.

Description

technical field [0001] The invention relates to the field of monitoring and control, in particular to a system and method for monitoring the displacement of transmission line towers. Background technique [0002] In most coastal areas of my country, natural disasters such as landslides and mudslides are prone to occur under severe weather conditions such as typhoons and heavy rainfall, which may cause landslides of power tower slope protection; In ice conditions, it is easy to cause accidents such as tower tilting, collapse, wire disconnection, and line tripping, which will affect the safe and stable operation of the power grid. Overhead power towers are distributed in a wide range. It is difficult to detect the inclination of towers in a timely and accurate manner by traditionally relying solely on power transmission operation and maintenance personnel to inspect lines one by one, and even the current implementation of drone inspections, because the settlement and deformatio...

Problems solved by technology

However, adding an inclination sensor not only reduces the reliability of the system, but also because it is difficult to maintain a level with the tower when the inclination sensor is installed, the probability of misjudgment and omission is high

[0007] The method of GPS high-precision positioning is to use differential processing on the signals of two GPS rover stations on the tower, and the accuracy can reach centimeter level, but an additional GPS reference station is required, and the cost remains high

Moreover, due to the complex location and environment of the power poles and towers, the distribution locations are remote, and the power lines stretch for hundreds of kilometers or even thousands of kilometers. They are located in mountains and farmland, so they cannot communicate in areas without signal and cannot get in touch with the outside world.

The overall cost is also relatively high, so the application is limited
