地铁信号系统中基于通信的列车控制(CBTC)系统的车-地通信技术随着城市的发展,客流量的增加、民用无线设备使用的干扰,已不能完全满足地铁信号系统的需求。能够提供大容量、稳定可靠的车-地双向数据传输、零干扰的LTE技术有效的解决了这一问题。本文从工程应用方面阐述了LET技术在地铁信号系统的具体应用。
Vehicle-to-ground communication technology of CBTC system in metro signaling system With the development of the city, the increase of traffic volume and the interference of the use of civil wireless equipment can not fully meet the needs of the subway signaling system. Can provide large capacity, stable and reliable car - to the two-way data transmission, zero-interference of LTE technology effectively solve this problem. This article elaborates the concrete application of LET technology in subway signal system from the aspect of engineering application.
