摘要
针对某信号系统要设备简单实用、维修维护少、运输效率与线路匹配的特殊需求,提出利用北斗卫星定位及其短报文功能构建新型列控系统。阐述了新型列控系统的技术特点及架构;对列车定位、接近区段确定等关键技术进行了分析;对北斗短报文时延、长度与控车需求的匹配措施进行了描述。
Aiming at special requirements for simple and practical design with less maintenance as well as transport efficiency matching the line of signal system,a new-type train control system using Beidou satellite positioning and short-message communicating is proposed.The technical features and architecture of the new-type train control system are described.And its key technologies,such as train location and determination of approaching section,are analyzed.In addition,measures for adapting the delay of Beidou short-message communication and the length of message to the requirements of train control are described.
