Abstract
The invention relates to a method and a system for realizing a creeping driving mode in a full-automatic operation system. Compared with the prior art, the invention has the advantages of automatic driving, accurate speed control, accurate parking and the like.
Description
Technical Field
The invention relates to the field of subway full-automatic operation systems, in particular to a method and a system for realizing a creeping driving mode in a full-automatic operation system.
Background
In the full-automatic operation system of the subway, a driver is not arranged on the train. The control mode of train operation is mainly that a vehicle-mounted signal system (ATO) sends a control command of train operation to a vehicle through a TCMS network, and the vehicle controls the automatic operation of the train according to the command (including traction, traction grade, braking grade and the like) of the vehicle-mounted signal system. Therefore, when the network between the vehicle-mounted signal system and the train is interrupted due to a fault, the train cannot receive the train control instruction of the signal system any more, the train stops in an interval, and the train cannot be driven to the platform in a manual driving mode due to the fact that no driver exists on the train. In order to deal with the scene, in the full-automatic operation system, another hard-wire interface between the vehicle-mounted signal system and the vehicle is added, and the interface is used as a standby interface of a network interface. Under the condition of network interface failure, the hard-wire interface can be started to realize the vehicle-mounted ATO vehicle control instruction, so that a part of control functions are realized, and the train can run to a station at a low speed.
The vehicle ATO controls the train to run at a low speed through a hard wire interface, which is called a creeping driving mode.
The current design method is that traction and braking commands are sent between a vehicle-mounted signal system and a vehicle through two hard-wire interfaces.
This approach has the following major disadvantages:
1) the train has low running speed and low efficiency, and needs a long time to run to a platform;
2) only a single traction grade and a single brake grade exist, and the comfort of passengers is poor;
3) because the braking grade is single, the platform can not be accurately stopped.
4) After the train arrives at the platform, the operation of automatically opening and closing the train door and the platform door cannot be realized due to the failure of stopping.
