The Design And Realization Of Tdcs Network Security System Of Zhundong Railway Company

Zhundong Railway Company is a wholly owned subsidiary of Yitai Group, is a coal-based, railway transport enterprise. The company is north to Zhoujiawan station, connecting with Dazhun railway, south to Zhungeerzhao station by way of Shagedu, connecting with Baoshen railway and through the Zhungeer mining area. There are9stations along the way, which is the main channel of coal mining transport of Yitai. Because of Zhundong company traffic becoming more and the pressure of transport increasing, the existing scheduling mechanism of company can not meet the transport requirements, which restricts the efficiency and improvement of Zhundong railway transportation. After repeated investigation and evaluation,Zhundong Railway company has decided to construct train dispatching command system(TDCS).TDCS is a huge project, its basic network directly connects to the stations.To ensure traffic safety, TDCS network system must be a safe operation and self-contained, while TDCS to do with the various units, in ensuring the safe operation of the network under the premise of sharing resources.In this paper, the special network and the use of redundancy mechanism are dedicated to ensure network security and reliable. Based on the TDCS network need analysis, TDCS network system designed principles and implementation of programs is put forward, as well as network security aspects using firewalls and intrusion detection, anti-virus and other advanced technologies, so as to establish a set of secure and reliable TDCS network system.Secure and reliable network environment is the prerequisite and basis for normal operation. Using a digital, networked, information technology TDCS is a revolutionary breakthrough the traditional command and control model,which will greatly reduce the labor intensity of the dispatcher, and increase transportation and production efficiency. The construction of the centralized scheduling based on TDCS system is the only way of Zhundong Railway realizing span type development. So the study of TDCS network security system will lay a solid foundation of Zhundong Railway schedule modernization.
