摘　　要：CTCS-2级列车控制系统对我国铁路信号是一项全新技术,其结构和实现方法尚未定型。本文在CTCS-2级技术条件框架基础上,提出一种采用无线机车信号和ATP实现CTCS-2级系统的方法。无线机车信号从CTC或TDCS分机获取临时限速值并从联锁获取进路信息,通过无线信道直接发送到车载ATP设备;ATP设备据此生成目标-距离模式曲线并按照不同监控模式控制列车。其优势是:(1)可省去相应有源应答器;(2)无线信息传输闭环确认,保证信息传输的可靠性;(3)无需进行车站电码化,也不存在轨道电路受到不同干扰影响信息传输问题。文章阐述了系统的基本结构和工作原理,并对系统的先进性、可行性及系统的可靠性和安全性进行了分析。CTCS-2 is one new technology in railway signaling in our country, it＇s architecture and implementation scheme have not been finalized in design. In this paper, An alternative scheme of using radio based cab-signaling and ATP equipment for realizing CTCS-2 is proposed on the basis of the technical terms about CTCS-2. Radio based cab signaling gets temporary speed restriction from CTC or TDCS extension and admission passage information from interlocking. The information is sent to ATP equipment by radio. ATP equipment makes objective-distance ode curves by the received data and controls trains according to different control modes. There are three advantages of this new system. First of all, it can leave out variable-data balises. Secondly, Closedloop affirmatrion guarantees safety of information transmission. Thirdly, it dispenses with coded track circuits at stations, and eliminates various interferenees to track circuits. The basic structure and oprating principles of the system are presented. The advantages, feasibility, reliability and safety of the system are analyzed.
