Title A Specific Design of An Application And Communication
Server for High-speed Railway Disaster Prevention Monitoring System
Abstract
In high-speed railway system, the real time values of meteorology, foreign body invade and earthquake are called disaster data. In order to monitor the disaster data, we build up a disaster prevention monitoring system for high-speed railway.
In this system, we need to build multipoint-to-multipoint communication between the monitor terminals and base stations. To meet the requirement, the development of an application and communication server is proposed in this paper. This paper will introduce the communication structure, functions, communication protocol and the specific design of the application and communication server. The program of this server is developed in an IDE called Visual Studio 2013. And we use C# as the programming language. This server has been tested in a real environment. After testing we found that the server is stable, each function or performance has met the requirement.
