In the related technology, a region controller is used as a third party for controlling the turning-back of a train, based on two sets of vehicle-mounted equipment on the train, under the condition that one set of vehicle-mounted equipment at a vehicle-mounted home terminal and the region controller keep communication link, the other set of vehicle-mounted equipment at a non-home terminal establishes communication link with the region controller in advance, then, registration is initiated to the region controller, and after the registration is successful, the head and the tail of the train are changed to control the turning-back of the train.
In this way, the non-home terminal needs to establish a communication link with the area controller, and the non-home terminal needs to request registration with the area controller after establishing the communication link with the area controller, which affects the turn-back success rate and the turn-back efficiency.
In the embodiment of the invention, when data are exchanged in the process of controlling the train to return, the vehicle-mounted equipment at the head end and the tail end are directly subjected to communication link to carry out data interaction, after the data interaction is finished, the vehicle-mounted equipment at the non-home terminal replaces the vehicle-mounted equipment at the home terminal to pull the train, and the vehicle-mounted equipment at the non-home terminal replaces the vehicle-mounted equipment at the home terminal to carry out communication link with a region controller or ground equipment so as to control the train to move out of the return track to a platform stop point.
Referring to fig. 1, the method includes:
s101: and when the first vehicle-mounted controller of the head office confirms that the turn-back instruction is received, generating a data packet according to the current state information of the train.
Optionally, the train current state information includes at least one of: the current head and tail positions and running direction of the train.
Further, the current train state information may further include: the driving mode, the door state, the registration state at the zone controller side, and the like, which are not limited.
Further, the first onboard controller (which is an onboard controller provided in the head-end of the train) may generate the data packet according to the current state information of the train when confirming that the turn-back instruction is received.
Optionally, in some embodiments, referring to fig. 2, generating a data packet according to the current train state information includes:

After the first onboard controller generates the data packet according to the current state information of the train, the data packet can be directly transmitted to the second onboard controller based on the established communication link, and then the second onboard controller is triggered to carry out traction control on the train.
Compared with the prior art, under the condition that one set of vehicle-mounted equipment at a vehicle-mounted home terminal is in communication link with a regional controller, the other set of vehicle-mounted equipment at a non-home terminal establishes a communication link with the regional controller in advance, then initiates registration to the regional controller, and switches the head and the tail of the train to control the train to turn back after the registration is successful, the embodiment of the invention directly sends a data packet to the second vehicle-mounted controller at the non-home terminal of the train, so that the data transmission performance is improved, and the train turn-back success rate and the turn-back efficiency can be improved.
S103: and the second vehicle-mounted controller analyzes and resets the data packet, and performs turn-back control on the train according to the result obtained by analyzing and resetting.
Optionally, parsing and resetting the data packet, and performing turn-back control on the train according to a result obtained by parsing and resetting, includes: exchanging the positions of the head and the tail of the vehicle, and inverting the operation direction to obtain the positions of the head and the tail of the vehicle after exchanging and the inverted operation direction; and performing turn-back control on the train according to the positions of the head and the tail of the train after interchange and the running direction after inversion.
The second vehicle-mounted controller can analyze the data packet, and reset data portions corresponding to the positions of the vehicle head and the vehicle tail in the data packet, namely, the positions of the vehicle head and the vehicle tail are exchanged, and reset data portions corresponding to the running direction in the data packet, namely, the running direction is reversed, so that the positions of the vehicle head and the vehicle tail after the exchange and the running direction after the reversal are obtained.
In this embodiment, when the first vehicle-mounted controller of the head end confirms that the turn-back instruction is received, a data packet is generated according to current state information of the train, the data packet is directly sent to a second vehicle-mounted controller of a non-head end of the train, the second vehicle-mounted controller analyzes and resets the data packet, the turn-back control is performed on the train according to a result obtained by analysis and resetting, since the vehicle-mounted devices at the head end and the tail end directly perform communication link, data interaction is performed, the vehicle-mounted device of the non-head end replaces the vehicle-mounted device of the head end to pull the train after the interaction is completed, the turn-back success rate and the turn-back efficiency of the train can be.
