铁路通信与信号一体化技术的思考

Regarding the Railway Communication and Signal Integration Technology

随着高速铁路和客运专线在我国不断建设发展,出于安全需要,列车运行对于铁路通信系统提出了更高的要求。通信网络的服务功能与通信质量必须具备与高速列车相匹配的技术能力。目前,现代通信技术、网络技术、计算机技术在铁路信号系统中逐渐应用,使传统的"信联闭"为主的列车运行控制方式向基于GSM-R技术的CTCS列车运行控制系统转变,改变了以地面信号作为主体行车信号的历史。文章通过分析当前铁路信号技术现状,提出了通信与信号一体化应不使用轨道电路检查列车位置的方案,优化了室内外联锁设备控制方案,提高了铁路信号现代化水平,减少了建造成本,向资源节约型社会发展需求等方面进行有益探讨。

With the development of high speed railway and the special line for passenger transport in our country＇s contin-uous development, the safe operation of trains put forward higher requirements for railway communication system, service function and the quality of the communication network must have the technical ability to match with the high speed train. At present, the modern communication technology, network technology, computer technology have been gradually ap-plied in railway signal system, the traditional“letter of closed” based train control mode change to the CTCS train con-trol system based on GSM-R technology, changed the ground signal as the main running signal history. Through the a-nalysis of the current situation of railway signal technology,the research purposes not using train circuit to inspect loca-tion of the train which optimizes the indoor and outdoor interlock device control programs and improves the level of mod-ernization of railway signals, reduces construction costs. It tries to meet resource-saving and other social development needs.
