The Research Of Beijing-Guangzhou High-speed Rail Transmission System Security

With the rapid development of High-speed Railway, the railway communication system is sustainable development as an important part of High-speed Railway. Transmission system provides safe, stable methods of communication for railway operation management, dispatching command, driving equipment monitoring etc. It is an important method to achieve unified command, unified scheduling and is important infrastructure for guarantee the safety of railway transportation, improve the efficiency, we will improve the management level. High-speed rail transmission system provides transport channel for GSM-R system, scheduling communication system and other kinds of communication subsystem, and provides transport channel for high-speed EMU train operation control, disaster prevention security monitoring etc.Transmission network security is an eternal theme. With the development of railway Information technology, the business continues to increase in transmission system. The security of transmission networks comes very important. So it is a important subject about the research of High-speed Rail transmission system security. Although we through the communication engineering design control and improve the mechanism of transmission security protection. In the process of maintenance, we through strengthening maintenance for fiber optic cable and transmission equipment and network optimization, we can avoid some problems on the influence of the transmission network, but can’t completely eliminate. So in order to improve the security and reliability of the transmission network, We must carry on the comprehensive design and concrete analysis in the entire network, so as to put forward a set of effective and feasible measures.In this paper, it introduced the relevant basic theoretical knowledge of optical transmission network. Then it analyzed the impact of the transmission network security factors and put forward the measures of increasing the safety of the transmission network. It combines the reality of daily work, We carried on the detailed and specific analysis about the security of Beijing-Guangzhou High-speed transmission system. Our opinions and Suggestions are given on Strengthening the transmission system security. In the hope that this aspect of the transmission network security research can play some of the realities.
