摘　　要：结合广播系统在地铁综合监控系统中的集成应用案例,着重对地铁广播系统进行研究。列举1条地铁线路作为典型的工程实例,包括14个车站、1座车辆段、1座控制中心,在各车站、车辆段、控制中心设有广播系统,主要用于对乘客进行公告信息广播和发生灾害时兼作防灾广播。介绍中心、车站、车辆段各级对广播功能的需求,在此基础上分析整条线路的广播系统的结构和典型配置。阐述各级广播的基本原理,对广播系统的各级控制流程和典型音频流程进行剖析。Citing a case of integrated application of public address system in the integrated supervisory control system of subway,this paper focuses on the study on subway PA. A typical project example is given： a subway line including 14 stations,1 depot and 1 operation control center is equipped with a PA system that performs at all levels of the main bulletin information broadcast for passengers and disaster prevention broadcast in the event of a disaster. A brief introduction is made for the broadcast function demand at all levels and on this basis the structure of the PA system and its typical allocation for the whole line is analyzed. Basic principles of broadcast at all levels are introduced. The control data flow and typical audio frequency data flow for the PA system at all levels are analyzed.
