A Hybrid Networking System for Dense Power Transmission Channels

Abstract

The invention relates to a mixed networking system for a dense transmission channel. The mixed networking system comprises a field network field, a long-distance network section and a data network section, which are sequentially connected; the field network is a wireless closed loop network consisting of an OPGW (Optical Fiber Composite Overhead Ground Wire) optical fiber access point and a wireless network access point; the OPGW (Optical Fiber Composite Overhead Ground Wire) optical fiber access point is arranged on an iron tower of a gathering point; the wireless network access point is arranged on the iron tower; the long-distance network section is an OPGW optical network; a gathering node of the OPGW optical network is arranged on transformation substations at two ends of a transmission line; and a data network section is an electric information special internal network. Compared with the prior art, the mixed networking system provided by the invention has the advantages that the robustness of a communication network is enhanced; the information data transmission rate is improved; and the network communication cost is reduced.

Description

technical field [0001] The invention relates to a hybrid networking system, in particular to a hybrid networking system for dense power transmission channels. Background technique [0002] At present, some results have been achieved in the application of hybrid networking technology in dense transmission channels in China, but the effect is not obvious in the current overall situation, and there are obvious deficiencies in actual use. For its reason, the means of communication mainly rely on public wireless networks, such as GPRS / CDMA / 3G, etc., and the use of wireless public networks has the following defects and disadvantages: [0003] The coverage of the public network is limited, especially it is difficult to cover the entire UHV / UHV intensive transmission line. During the operation of the transmission line, the more mountains and mountains, inaccessible areas, no signal or weaker signal, the more it is necessary to maintain smooth communication. [0004] The types of se...

Problems solved by technology

When the amount of single-channel data collection is small, the bandwidth can meet the demand. For dense-channel multi-data collection and video, generally only photos with low resolution can be transmitted, more than a dozen per minute, which is difficult to meet the needs of data and video. Services that require real-time, smooth, high-definition data, etc.

[0005] The security of the public network itself is low, resulting in the inability to share system resources through the internal network in the dense power transmission channel using the public network transmission method, that is, the degree of interaction and openness is not high, and information islands are common. cause great inconvenience

[0006] The charging service of the public network will lead to high operation and maintenance costs, increase the expenses of the operating unit, and bring obstacles to large-scale promotion and use

[0007] Network management is difficult. Once the system is changed or fails, it must be resolved through consultation with the telecom operator. The time to deal with the problem cannot be guaranteed, thus threatening the safe operation of the power system
