Signal-free area power transmission line data transmission system based on wireless network bridge

Abstract

The invention provides a signal-area-free power transmission line data transmission system based on a wireless network bridge, and relates to the technical field of power systems. The signal-free area power transmission line data transmission system based on the wireless network bridge comprises a plurality of poles and towers, each pole and tower comprises a wireless transmission device, and the plurality of poles and towers are connected with the wireless network bridge through the wireless transmission devices; the wireless transmission device comprises a first wireless transmission module used for receiving data sent by a previous base tower; the second wireless transmission module is used for sending the data to a next base tower; the first wireless transmission module is connected with the second wireless transmission module; andthe last base pole tower in the plurality of pole towers comprises a transmitting module connected with the first wireless transmission module and the second wireless transmission module, and the transmitting module transmits received data information to a monitoring center. According to the invention, a power transmission line networking scheme based on the high-capacity wireless network bridge can be realized, and data information can be transmitted back to a monitoring center, so that the operation condition of the power transmission line can be mastered.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a transmission line data transmission system in a non-signal area based on a wireless network bridge. Background technique [0002] Transmission lines play an important role in the transmission of electric energy in the power system. At present, most transmission lines pass through uninhabited areas such as mountains, Gobi, and deserts, cross rivers and lakes, and pass through areas with complex environments and inaccessible areas such as no-signal areas. Transit transmission lines may even pass through primitive forests with extremely harsh natural conditions. In extremely difficult areas, there is no public network signal coverage, and it is difficult to ensure personnel safety, which brings severe challenges to daily operation and maintenance management, accident inspection and emergency repair. Therefore, online monitoring of transmission lines is very important. [0...

Problems solved by technology

However, the public network has obvious problems such as poor security, poor reliability, high post-communication costs, and small coverage; while optical fiber communication consumes a lot of power and has high initial costs, which is contrary to the requirements of the State Electricity Regulatory Bureau's "Security Protection for Secondary Power Systems"

At the same time, since the no-signal area does not cover the mobile base station signal, the operation status of the online monitoring equipment such as the image of the transmission line in the no-signal area cannot be obtained in time
