摘要
高速铁路取消地面信号机,车载设备直接从地面设备提取信号控制机车运行。为确保信息传递的安全可靠,需配备冗余的信息传输系统。本文介绍了一种轨间环线车地通信系统的主要功能和技术指标。
Ground signals are removed from high-speed railway, and on-board equipment directly pick up signals from ground equipment to control train operation. The redundant information transmission system is needed to ensure the security and reliability of information transmission. The article introduces the main functions and technical indexes of train-to-ground communication system in track loops.
