Problems solved by technology

[0006] Among them, the electric power wireless system is a solution that is more suitable for transmission lines. As a distributed architecture of the central unit BBU+remote unit RRU, it can make full use of the power optical cable resources and power dedicated wireless frequency bands on the transmission line, but the original The system is limited by the number of cascaded RRUs, and the coverage range is within 100 kilometers. The application of longer distance transmission lines is relatively limited.

Abstract

The present invention proposes a maintenance method for a layered hybrid communication system suitable for power transmission lines, which uses a layered multi-hop hybrid network communication system that combines power-over-light wireless communication technology and multi-hop wireless communication technology to support the state of power transmission lines The transmission of sensing data adopts the linear link maintenance method to improve the reliability of data transmission; the system includes the central base station BBU, the remote unit RRU, the wireless multi-hop unit and the wireless terminal; the maintenance method solves the reliability of the chain communication network, Prevent network interruption caused by network single point failure.

Description

technical field [0001] The invention relates to a maintenance method, in particular to a maintenance method of a layered hybrid communication system suitable for power transmission lines. Background technique [0002] At present, each urban-level power supply company has built a power communication transmission network based on optical communication within the main urban area. The urban optical fiber backbone network covers 35KV to 220KV substations, and some developed areas have covered 10KV substations to 500KV urban substations. However, for application scenarios in remote areas, such as transmission lines, due to factors such as geographical environment, economic costs, and communication characteristics, there is currently no effective communication system to support the status monitoring effect of transmission lines. [0003] Different from public network communication, power communication presents its own business characteristics. Most of the services are fixed, while...
