南昌地铁3号线综合监控系统冗余机制研究

地铁综合监控系统集成电力监控系统、火灾自动报警系统、环境与设备监控系统、站台门系统、视频监视系统、门禁系统、乘客信息系统等多个子系统,实现各子系统监视与控制功能,在地铁正常运营和应急联动中发挥重大的作用,综合监控系统的可靠性和安全性要求极高,因此综合监控系统在设计和实施过程中都采用冗余设计,包括服务器、前置处理机、交换机等关键设备及软件的冗余,保障整个系统安全稳定运行。

The integrated metro monitoring system integrates many subsystems,such as electric power monitoring system,automatic fire alarm system,environment and equipment monitoring system,platform door system,video surveillance system,access control system,passenger information system and so on.It realizes the monitoring and control functions of each subsystem and plays an important role in the normal operation and emergency linkage of the metro.The reliability and security requirements of the integrated monitoring system are extremely high.Therefore,the integrated monitoring system adopts redundancy design in the design and implementation process,including server,pre-processor,switch and other key equipment and software redundancy,so as to ensure the safe and stable operation of the whole system.
