浅析列车自动控制系统信号系统接口方案

为实现客运专线的列车自动控制,信号系统接口方案的设计至关重要。接口方案是影响工程的重要因素,接口方案的设计应考虑周全,否则将影响后期运营的服务质量。对客运专线信号系统的列车运行控制系统、联锁系统、调度集中系统和集中监测系统等4个系统接口方案进行了分析,并阐述每个子系统的内部和外部接口。所分析的接口方案均符合中国列控系统的技术规范,以供客运专线信号系统的接口管理和设计参考,但在建设实施中还应根据其适应运营的特殊要求加以选择。

Interface Scheme of the Signal System in Train Automatic Control System

To achieve automatic control of passenger trains on passenger dedicated lines （PDL）, design of signal system interface scheme is a critical factor. Interface scheme is an important factor affecting the project, interface scheme should be designed under thorough consideration, otherwise the operation and service quality might be affected. This paper analyzes the interface schemes of the train operation control system, interlock system, CTC and centralized monitoring system which are the components of the signal system of PDL. Both internal and external interfaces are described for each of these systems. The interface schemes discussed in this paper are all in line with the technical specifications of China′s train control system, and could used as reference for the interface management and design of the signal system of PDL. However, the interface scheme should be selected on the basis of the special requirements on operation.
