上海轨道交通10号线TETRA专用无线系统的可靠性和应用

Reliability an d Application of TETRA Dedicated Wireless System on Shanghai Rail Transit Line 10

TETRA(泛欧集群无线电)凭借极高的可靠性、可扩展性和实用性对行车安全起着至关重要的作用,是轨道交通专用无线通信的首选技术。以TETRA在上海轨道交通10号线的应用为例,介绍了TETRA专用无线网络的可靠性设计及其无线覆盖方式,在应急管理方面的高可靠性及可扩展性。结合TETRA在10号线车厢应急对讲电话、车厢广播、列车肖动监控、视频监控的应用分析可知,TETRA可为全自动运行线略通信系统的安全、稳定运行提供完善的解决方案。

Due to the high reliability,scalability and practicality,the Trans European Trunked Radio(TETRA)protocol plays a vital role in metro traffic safety,and thus becomes the first choice for metro-specific wireless communications.Taking the application of TETRA on Shanghai metro Line 10 as an example,the reliable design and wireless coverage,the high reliability and scalability in emergency management of TETRA dedicated wireless network are introduced.According to an analysis of TETRA applied in intercommumcation phone(IPH),PageAdmin system(PA),automatic train supervision(ATS)and closed circuit television(CCTV)of Line 10 carriages,TETRA is regarded as the best solution tor the safety and stability of FAO communication system.
