Abstract

The invention discloses a line sag online detection system based on differential locating. The line sag online detection system comprises a base station and a monitoring station; the base station is fixedly provided with a solar energy power supply system, a first satellite receiving module, a first CPU, a first wireless data radio, a 4G communication module and a site extended communication interface; and the monitoring station is fixedly provided with a second satellite receiving module, a second CPU, a second wireless data radio, a pose and motion measuring unit, a non-contact infrared temperature measurement sensor and a line electricity taking module. According to the line sag online detection system based on the differential locating, the base station is arranged on a tower or otherreliable fixed positions, the monitoring station is installed at a line sag point, a satellite differential locating technology is adopted, the base station and the monitoring station receive satellite signals at the same time, real-time differential resolving is carried out through wireless differential links, the elevation and horizontal positions of monitoring points are measured, and the real-time monitoring of the line sag is realized through the combination of data such as line temperature measurement and pose and motion measurement.

Description

technical field [0001] The invention relates to the technical field of line sag detection, in particular to an online line sag detection system and detection method based on differential positioning. Background technique [0002] In the transmission line, if the sag height of the conductor exceeds a certain range, the conductor will discharge due to insufficient crossing distance, endangering the power production and the safety around the transmission line. Therefore, the sag height of the conductor must be limited within a certain threshold range. To ensure the safe and stable operation of transmission lines. [0003] Traditional sag monitoring methods include different length method, angle method, gear end observation method, etc. These methods need to send inspection personnel to the site for measurement, and their accuracy is greatly affected by angle measurement and visual estimation readings, and the measurement process is cumbersome. And the cycle is long and the cos...
