The invention discloses a visual channel inspection device and a visual channel inspection method for an overhead transmission line. The device is arranged on a wire close to a base tower of the overhead transmission line, and comprises a signal collection module, a data processing module, a wireless network transmission module and an energy supply module, wherein the video signal collection module 1 and the wireless network transmission module are both connected with the data processing module; the energy supply module is connected with the video signal collection module, the data processing module and the wireless network transmission module; the data processing module is a direct spread DSSS module and an MPEG4 compression code module; signal transmission is performed in a cascading bridging manner, channel inspection efficiency of the power transmission line is improved, and hidden dangers of the channel of the power transmission line can be found in time. According to the device and the method provided by the invention, a wireless ad hoc signal transmission mode is used, and thus the problem about high traffic charge caused by the use of a large-scale 3G / 4G mobile communication network is avoided; inspection expense of the power transmission line in complex terrain such as mountains is greatly saved, and inspection efficiency is improved.
Description
Technical field [0001] The invention belongs to the technical field of transmission line inspection, and in particular relates to a visual inspection device and method for overhead transmission line channels. Background technique [0002] With the rapid development of power construction, the scale of ultra-high voltage and UHV power grids is getting larger and larger, and the operation and maintenance of power grids under complex terrain conditions are getting more and more difficult. High-voltage transmission lines pass through areas with complex terrain, variable climatic conditions, long transmission distances, and transmission line accidents often occur. The huge power transmission network brings a lot of inconvenience to the work of the operators, so it is essential to observe and inspect the working conditions of the line. The traditional method uses regular manual inspections. This method is time-consuming and laborious and has an overhaul period. The line conditions duri...
