地铁工程车智能安全监控系统与信号系统接口方案研究

Research on Interface Scheme Between Intelligent Safety Monitoring System and Signal System for Metro Maintenance Trains

目前,地铁工程车主要依靠乘务员经验、目视信号等方式操控车辆行进。为了改变工程车作业无技防手段的现状,地铁工程车智能安全监控系统得到广泛应用,该系统可对冒进信号、异物侵限、挤岔脱轨、冲撞车挡、列车冲突等安全事故进行智能化安全防护,为实现上述功能需解决联锁信号上车的问题。依据目前上海地铁联锁信息获取情况,文章主要阐述了从段场联锁侧、各线路线路侧运行控制中心-列车自动监控系统(OCC-ATS)侧及3C大楼数据中心-列车自动监控系统(3C-ATS)侧获取联锁信息的3种方案,并对各方案进行了细致分析及对比研究。在满足系统安全防护条件下,ISM系统与管理网CFEP接口方案集成度高、可靠性高,对其他系统的影响小,可实现信息的互联互通。

Metro maintenance train driver mainly relies on working experiences and visual signals to control the vehicles.In order to change the status quo that there are no technical defense methods for maintenance train operation,ISM system is widely used.The system can realize intelligent safety protection from safety accidents such as the signal of rushing in,the limit invasion of foreign matters,the derailment of the switch,the collision of the car block,the train conflict,etc.To realize the above functions,it is necessary to solve the problem of onboard signal interlocking.According to the current situation of Shanghai Metro interlocking information acquisition,this paper mainly expounds three schemes to obtain interlocking information from the interlocking side of the depot,the OCC-ATS side of each line and the 3C-ATS side,and analyzes and compares each scheme.The interface scheme between ISM system and management network CFEP has high integration,high reliability,low impact on other systems,and can realize the interconnection of information under the condition of meeting the system safety protection.
