摘　　要：地铁信号系统保障列车安全运行时,必须实现与防淹门系统的安全、高效联动控制。详细介绍一种地铁信号系统中对防淹门设备进行安全防护的技术方案与实现方式。首先提出系统接口设计时需要考虑的原则,并结合系统运营场景分析,描述信号系统的控制行为;然后根据信号系统的需求,采用UML方法建立计算机联锁子系统的用例图、状态图和顺序图模型,从不同角度分析系统的动、静态行为;最后对系统实现的硬件接口设计方案进行阐述。在广州地铁7号线工程项目中的成功应用表明:该方案功能完整,边界清晰,交互简单,能安全、高效地与防淹门系统进行联动控制,具有进一步推广应用,并纳入城市轨道交通行业技术标准的价值。In order to ensure safe operation of the train,metro signal system should realize safe and efficient joint control with the floodgate system. A solution and implementation of the safety protection of floodgate equipment in a metro signal system is introduced. Firstly,the principle of the system interface design is put forward,and the control activities of the signal system are described based on system operation scenario analysis. Secondly,according to the requirements of the signal system,the use case graph,state diagram and sequence diagram models of the computer interlocking subsystem are set up in UML to analyze the dynamic and static behavior of the system from different perspectives. Finally,the hardware interface design scheme of the system is described. With the successful application in Guangzhou Line 7 project,the solution shows functional integrity,clear boundary and simple interaction,and ensures safe and efficient joint control with the floodgate. It has the value of further promoting application and incorporating in the technical standard of the urban rail transit industry.
