文中介绍以3G通信技术为基础组建新型铁路行车安保系统的基本原理、技术路线和实施设想。利用3G图像处理和无线监控技术组成行车安全监控系统,可以解决传统系统中监控信息不能向运动的机车实时传送而导致对突发情况猝不及防等重大问题。同时利用该系统还可以为客运列车的旅客提供多种信息和多媒体增值服务,使该系统建设有可能成为铁路客运服务升级换代的重要发展方向,并实现3G一网多用。
This paper introduces the basic principle, technical route and implementation of the new type of railway driving security system based on 3G communication technology. The use of 3G image processing and wireless monitoring technology to form a traffic safety monitoring system can solve the major problem that the monitoring information in the traditional system can not be transmitted to the moving locomotive in real time, resulting in the unexpected situation being caught off guard. At the same time, the system can also provide a variety of information and multimedia value-added services for passengers of passenger trains, so that the construction of the system may become an important development direction for upgrading and upgrading of railway passenger service and realize the multi-use of 3G network.
