Research on automatic identification and monitoring technology for OCS non-stop areas
When the urban rail transit train passes through the insulated joints of the anchor section of OCS,the pantograph will be in transition from the working branch of the OCS to the non-working branch,which will form a transition area that is not suitable for stopping.In the dynamic traveling process of the train,passing through this area has no effect on the pantograph current,if the train stops in this area,and the current process of the pantograph is maintained for a period of time,it is very likely to cause a pantograph-OCS accident.To avoid major accidents such as the pantograph-OCS damage caused by the train stopping too long in the transition area of the OCS,this article introduces the wireless radio frequency technology and train signal control technology,and puts forward a method for automatic identification and monitoring of train stopping in the transition area of OCS insulated anchor section joints during main line operation,which utilizes the on-board monitoring device to monitor the real-time speed and position information of the train,and once the train is identified to be stopping in a dangerous area,the on-board monitoring device will immediately trigger the early warning system to control the pantographs entering the dangerous area to lowering automatically and send sound and light alarms to the driver,so as to effectively prevent the occurrence of pantograph-OCS accidents and enhance the safety of the main line operation of trains.
