| 摘 要： | 随着城市轨道交通运行控制系统向系统化、网络化、信息化、智能化方向的发展,基于通信的列车控制(CBTC)系统已成为城市轨道交通主流的信号系统,可实现车地连续式双向通信。结合实际使用情况,阐述了现CBTC系统使用的2.4 GHz无线通信的性能,通过对比上海现使用的泰雷兹和卡斯柯两套CBTC系统2.4 GHz无线通信实际使用及故障情况,提出了针对性的改进方案。针对LTE(长期演进)通信技术在CBTC系统无线通信中的使用进行了初步分析,并提出相应的2种通信方案。

| Abstract: | With the development of rail operation control sys-tem to the direction of systemization,networking, information technology,intelligent communication and signal integration, CBTC has become the mainstream technology in rail transit communication system,which can realize the continuous two-way communication between train and ground control system. Based on the actual application,the performance of 2.4 GHz wireless communication used in CBTC system is expounded. By comparing the practical use and failures of two 2.4 GHz wireless systems of Terez and Casco 2 CBTC system applied in Shanghai metro,the design of CBTC wireless communica-tion that adopts LTE technology is preliminarily analyzed,2 corresponding communication schemes are proposed. |
