地铁移动闭塞信号系统车地通信传输技术研究

摘要

地铁移动闭塞信号系统在系统结构和功能日趋一致或接近的情况下，车—地双向连续通信方式是系统的关键技术之一和主要区别。本文就地铁移动闭塞信号系统的几种车地通信的优缺点进行了简单分析，并就与 PIS 等的干扰解决措施进行了简单介绍。%Structure and function of the movable block signal system become increasingly close and consistent case. Train g-round communication system is one of the key technology and main difference. Train ground communication system of the movable block signal system advantages and disadvantages are analyzed simply, and with PIS interference measures were intr-oduced.
