MSTP内嵌RPR技术在地铁通信中的应用分析

Application Analysis of MSTP-embedded RPR Technology in Metro Communication

地铁是在一个封闭的环境中运行的大系统，地铁传输系统作为轨道交通信息、控制系统的基础网络，承载着语音、控制、监控信号和图像等业务，这些业务对于行车安全以及列车控制、运营和管理都有着非常重要的作用。出现任何问题，都会涉及到行车、调度甚至乘客的安全。那么，如何保证这些业务的稳定和可靠传送，以实现地铁运行的畅通无阻呢？MSTP内嵌RPR技术的出现将会很好的解决地铁专用传输网的构建问题。

Subway is a big system operating in a closed environment. As a fundamental network of rail transit information and control system, metro transmission system bears the services such as train controlling, signal monitoring and voice ＆ image processing, which plays an important role for not only the traffic safety, but also the control, operation and management of trains. Any problem may affect the safety of traffic, scheduling and passengers. How can we ensure the stability and reliable transmission of these services so as to realize the smooth and safe running of subways. MSTP-embedded RPR technology will solve the problem of transmission network construction specifically for subways.
