摘　　要：[目的]信号系统对PSD(站台门)的控制是确保城市轨道交通稳定运营的关键环节,信号系统与PSD系统之间的接口对于稳定高效地控制PSD非常重要,因此有必要深入分析信号系统与PSD系统之间的接口,对比传统的继电接口和新型的PSDC(站台门控制系统)接口,并对PSDC接口直控PSD的方案进行分析。[方法]详细解析了采用继电接口和PSDC接口的系统架构,并从设备结构、信息交互、设备维护、运维支持等方面,对继电接口和PSDC接口进行对比。基于接口结构,阐述了PSDC接口直控PSD的方案。[结果及结论]与继电接口相比,PSDC接口通信速度更快,安全性更好,信息交互过程更为简短,能全面直观地显示设备状态及参数变化情况,具有明显优势。PSDC接口直控PSD的方案能减少中间设备对命令/非命令信息的转接,便于集中监控与管理,提升运营效率。[Objective]The control of PSD(platform screen doors)by signaling system is crucial for ensuring urban rail transit stable operation.The interface between the signaling system and the PSD system is equally important for the stable and efficient control of PSD.Therefore,it is necessary to conduct an in-depth analysis of this interface,comparing traditional relay interfaces with the new type of PSDC(platform screen door control)system interface,and to analyze the scheme of PSD direct control using PSDC interface.[Method]A detailed analysis of the system architecture using relay interfaces versus PSDC interface is provided.These interfaces are compared from equipment structure,information exchange,equipment maintenance,and operation-maintenance support perspectives.Based on the interface structures,the scheme of PSD direct control using PSDC interface is discussed.[Result&Conclusion]Compared to the relay interface,PSDC interface features faster communication speed,better security,and shorter information exchange process,presenting a comprehensive and intuitive display of equipment status and parameter changes with obvious advantages.The above-mentioned scheme reduces the need for intermediate devices to transmit the command and non-command information,facilitating centralized monitoring and management,and thereby enhancing operational efficiency.
