CTCS-2在城际铁路中的适应性研究

研究目的:在城际铁路技术标准尚未形成的前提下,提出将CTCS-2应用于城际铁路信号系统的设计思路,为城际铁路列控系统体系构建提供参考。研究结论:(1)对CTCS-2体系进行优化和少量改造,可满足城际铁路的运输需求,将CTCS-2应用于城际铁路方案可行。(2)对CTCS-2的优化方案:将CTCS-2应用于城际铁路,由于站间距较小,工程投资较大,采用多站合用一套联锁设备和列控中心设备的方式,可有效降低工程投资。(3)改造方案:通过增加车载ATO单元和少量地面应答器,对CTCS-2的地面和车载设备进行适当改造,能够实现ATO相关功能。

The Adaptation of CTCS - 2 in the Inter - city Railway

Research purposes: While the technical standards for inter-city railway have not been formed,this paper proposes the thinking that CTCS-2 can be used in inter-city railway signal system.The design thinking will provide a reference for the building of train control system in inter-city railway. Research conclusions:(1)With small amounts of transformation and optimization for CTCS-2 system,the CTCS-2 can meet the transport demand of inter-city railway.The scheme of using CTCS-2 in inter-city railway is feasible.(2)The optimum proposal of CTCS-2: When CTCS-2 is used in inter-city railway,due to short distance between stations and great engineering investment,the author proposes a scheme that adjacent stations can share a set of interlocking and Train Control Center(TCC) equipment.And this way can reduce the engineering investment effectively.(3)Technical upgrading proposal: The wayside and onboard equipment of CTCS-2 can be reformed properly by increasing onboard ATO units and a small number of balise to achieve the ATO-related function.
