An Improved of Information Transmission Mode of High-speed Railway Centralized Traffic Control System

The network communication of the centralized traffic control(CTC) is one of the most important aspect that cause the CTC fault, so it has important impact on the CTC's normal work. The network construction, channel and the route realization method of the CTC used now can make the facility to miss data, delay information or break off the communication and so on. Using the loop net and the double channel among the railway station, the information transmission double redundancy has been improved and not change the hardware of the CTC. Through the example of Qing-Rong interurban railway of the Jinan Railway Bureau, it has proved that the method in the paper can effectively increase the stability of the CTC.
