Communication Network In Railway Marshalling Yard

In the railway industry, the railway communication is the basement oftransportation and production, it is the important symbol of railway modernization.But the railway information can’t leave the railway communication. Railwaycommunication is a set of communication system constructed for railwaytransportation, production, management and life service.Transportation network is one important component of railway communicationand the essential technical support. The passage mainly discussed the composition ofrailway communication and the railway transmission system composition andworking principle, a detailed account of the SDH transmission and access networkstructure, function and the current application in the railway, especially introduced thenetwork and the concepts and principles of program-controlled exchange technology.Combining with a project example of Marshalling Station, According to therequirements of the communication reformation, Step by step analyzing marshallingstation communication system capacity, the network structure, protection style andcommunication line construction scheme. Then according to the principle ofcommunication network, taking wired communication transmission network design asthe important part, the design of the project each system implementation scheme，reflects the station communication characteristics.
