Modern urban rail transit communication system is a complex system with multiple sub-systems, various types of system equipment, and each has its own network management and scattered installation locations. Therefore, it is necessary to set up a centralized alarm system on the whole communication system for effective and centralized maintenance and management. Based on the application of the centralized alarm system in Suzhou rail transit Line 1, this paper explains the necessity of setting up this system, and focuses on the scheme design and application of this system.%现代城市轨道交通通信系统是一个复杂系统,包含多个子系统,系统设备种类多,且都有各自的网管,安装地点分散,因此有必要设置集中告警系统对整个通信系统进行有效的集中维护管理.结合集中故障告警系统在苏州轨道交通1号线的应用,说明了设置该系统的必要性.通信集中告警系统普遍采用协调方式实现.由于采用模块化设计,功能强易于扩展,已成为轨道交通通信系统不可缺少的一部分,为降低运营成本,提高通信运营维护效率提供了重要保证.重点阐述了通信集中告警系统的方案设计,并对该系统的应用情况做了介绍.
