城市轨道交通车站新型应急照明和疏散指示系统设计

城市轨道交通车站中传统的应急照明和疏散指示照明均由交流220V电源供电,随着新的应急照明和疏散指示系统国家规范执行,既有的设计方案已不满足规范要求。文章介绍了一种新型的应急照明和疏散指示系统设计方案,新方案保留了传统方案中的备用照明仍由EPS供电,新增了一套疏散指示照明系统,新系统可将城市轨道交通常规交流220V电源转换成直流36V电源给疏散灯具供电,并且新系统增加了系统主机和相应的控制系统,具备通信和监控功能,可实现对整个系统的实时监视和控制,极大地提高了疏散照明指示系统的安全性、可靠性和新进性。

The traditional emergency lighting and evacuation indication lighting in urban rail transit stations are powered by AC220 V power supply. With the implementation of the new national standard for emergency lighting and evacuation indication system,the existing design scheme can not meet the requirements of the new standard. This paper introduces a new design scheme of emergency lighting and evacuation indication system. The new scheme retains the standby lighting in the traditional scheme, which is still powered by EPS. A new set of evacuation indication lighting system is added. The new system which can convert the conventional AC 220 V power into the direct current 36 V power supply for evacuation lamps, and the new system adds a system host and corresponding control system with the function of communication and monitoring. The new system can realize the real-time monitoring and control of the whole system, thereby greatly improves the safety, reliability and advancement of the evacuation lighting indication system.
