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。
Combined with the integrated application of broadcasting system in subway integrated monitoring system, this paper focuses on the study of subway broadcasting system. A typical subway project is listed as an example. It consists of 14 stations, a depot and a control center. Broadcasting systems are provided at stations, depots and control centers, which are mainly used for broadcasting announcements to passengers and Disaster prevention broadcast in case of disaster. Describes the demand for broadcast functions at all levels of the center, stations and depots, and analyzes the structure and typical configuration of the broadcast system of the entire line on this basis. Describe the basic principles of broadcast at all levels, the broadcast system at all levels of control processes and typical audio process analysis.
