Abstract

The invention relates to a remote monitoring method for a power transmission line. The method includes following steps: video signals of the power transmission line obtained by a camera are inputted to a video acquisition terminal; the video acquisition terminal converts the video signals to audio and video data streams for compressing and uploads the compressed audio and video data streams to a monitoring center, and the monitoring center decompresses the received audio and video data streams and performs real-time monitoring. According to the method, remote on-line monitoring is realized at a mobile terminal, and the monitoring efficiency is improved; and the acquisition terminal receives control signals emitted by the monitoring center, and the camera is controlled via a holder lens controller.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a remote monitoring method for power transmission lines. Background technique [0002] Power transmission is achieved by using a transformer to boost the power generated by the generator, and then connecting it to the transmission line through circuit breakers and other control equipment. According to the structural form, transmission lines are divided into overhead transmission lines and cable lines. The overhead transmission line is composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and is erected above the ground. According to the nature of the transmission current, power transmission is divided into AC transmission and DC transmission. The basic process of power transmission is to create conditions for the transmission of electromagnetic energy along the direction of the transmission line. The ...
