摘要： 为实现轨道交通的运营安全保障，提高出现事故后的应急响应和维保效率，提出一种将各条轨道交通的地铁控制中心组织成结构化的P2P网络，构建面向轨道交通电力系统数据的分布式发布订阅系统平台，提高数据异地的使用效率和共享，为电力系统故障的快速维保提供信息支持。发布订阅系统的地铁控制中心推送电力系统数据到网络节点，当电力系统出现故障时，维保人员可以订阅方式从网络系统中及时得到故障报警、设备信息和现场环境参数，实现故障期间各部门抢修程序的并行执行。应用结果表明，该系统平台能有效提高轨道交通故障响应速率和维修效率。

Abstract: In order to guarantee the rail transit operation safety, improve efficiency of emergency response and maintenance when an accident happens, this paper proposes constructing the P2P network based publish/subscribe system of the rail transit data and transmitting data and information to the subscriber of which subscription filter matches the published event. The control center in publish/subscribe system pushes power system data to network nodes, when there is a failure of power system, maintenance personnel can timely obtain the fault alarm, power system information and on-site environmental parameters by subscribing to the network system. During the period of the system failure, the parallel execution of the repair program can be executed. Application results show that publish/subscribe system effectively improves the response rate and maintenance efficiency of rail transport failure.
