Automatic turn-back control method for unmanned train

Abstract

The invention discloses an automatic turn-back control method for an unmanned train. Vehicle-mounted control systems are arranged at the A end and the B end of the train, after the vehicle-mounted control system at the A end controls the train to stop at an unmanned turn-back area, the following steps are performed, specifically, S1, the health status and the network connection status of the vehicle-mounted control system at the B end are supervised; S2, if the conditions are normal, the default end-changing operation is performed, and the control right is transferred to the vehicle-mounted control system at the B end; and S3, if any of the two conditions are not met, then a non-end-changing strategy is executed, the train is continuously controlled by the vehicle-mounted control system atthe A end, the train is pushed from the unmanned turn-back area to a station to stop by a reverse pushing method, and then the train is handed over to a driver to get on and process. The automatic turn-back control method for the unmanned train greatly improves the availability of unmanned automatic turn-back and reduces operational congestion and the risk of manual rescue in the unmanned turn-back area on the basis of not increasing the hardware cost of a system.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an automatic turn-back control technology. Background technique [0002] In the CBTC control system of rail transit, all support the unmanned automatic return function (switching the operating direction): that is, at the terminal station, after disembarking passengers, the driver gets off to the platform to press the return button, and then the on-board system automatically controls the train to drive into the unmanned Passengers turn back to the turn-back area, then complete the train change end in the turn-back area, then automatically drive out of the turn-back area, stop at the platform, and wait for the driver to get on the train. [0003] like figure 1 As shown, the current CBTC on-board system basically adopts a double-ended configuration, that is, a set of on-board control systems (A, B in the figure) are arranged at each end of the train, and each on-board control ...

AI Technical Summary

Problems solved by technology

[0004] As mentioned above, unmanned automatic turn-back is a necessary operation for switching up and down lines during subway operation. In the current design scheme, such as figure 2 As shown, if the communication between the two systems at the A and B ends fails, or the A end system itself fails, the reversing operation will not be possible in the uninhabited turn-back area. The turnaround area is the rail area, and there is no corresponding platform for getting on and off the train. Rescue will be very troublesome, which will block the rail transit operation and bring the risk of rescuers getting off the rail area
