The biggest bright spot of the unmanned subway train is to adopt an advanced full-automatic control solution, and the sleeping, awakening, starting, stopping, equipment management of the train and the coping with faults and emergency situations can be realized without the control of a driver. However, unmanned driving is not unmanned management, and the train running process must be monitored and controlled in real time. Based on the characteristics of full-automatic operation, train air conditioner setting, passenger and control center conversation, vehicle-mounted PIS broadcast setting and the like can be remotely controlled in the control center, communication with passengers or adjustment of train parameters can be facilitated in time, and operation service quality is effectively improved. The current Train control system is mainly implemented by an Automatic Train monitoring system (ATS) system. The train remote control interface provided by the common ATS is relatively fixed and simple, the realized interface function is relatively single, the control of a single train is basically realized, the intellectualization is relatively deficient, and the modern operation requirement cannot be met. In addition, the more troublesome problem is that the train remote control through the ATS has the problems of complicated network structure, repeated information transmission, difficulty in troubleshooting and large required network resources. In addition, the remote control interface generally provided by the ATS is relatively fixed and simple, the realized interface function is relatively single, basically, the ATS basically controls a single train, the intelligence is relatively deficient, and the ATS cannot meet the operation requirement of the modernization. From the perspective of safety and reliability, only a single train remote control channel is provided, and under the condition that the control channel is unavailable, the control function has no backup mode, and the emergency situation which may occur cannot be dealt with.

In conclusion, how to realize a new method for more safe, reliable, maintainable and extensible remote control of trains further improves the intelligent level of remote control of full-automatic trains and ensures safe and smooth travel of passengers becomes a technical problem to be solved.
