[0035] Example 1

[0036] refer to Figure 1 As shown, a method for turning back a train at any position is shown in the figure, and the method for turning back a train at any position includes the following steps.

[0037] Step S1: The dispatcher sets a new reverse running head code and selects the "immediate return" command for the communication train that needs to change ends and run in the reverse direction on the ATS system dispatch workstation interface;

[0038] Preferably, the head code setting range in step S1 includes all turnaround areas and platforms.

[0039] Step S2: The communication train stops according to the reverse running head code and the "immediate return" command.

[0040] Preferably, step S2 also includes: after the communication train determines that the train is at zero speed, it reports to the ATS that the train has stopped.

[0041] Step S3: The ATS system sends a "total cancellation" command to the interlocking system to release and unlock the route that has been requisitioned for the original direction of the communication train. Figure 1 Among them, the route starting from F4 does not include 6G.

[0042] Preferably, step S3 also includes: the interlocking system closes the start signal according to the "total cancellation" command, and the route section that has been requisitioned in the original forward direction cannot be requisitioned for the communication train. Figure 2 In the example, F4 is the starting route.

[0043] Step S4: ATS allocates a route from the rear of the train to the reverse destination to the interlocking system based on the stopped status reported by the communication train and the reverse run head code. The route can be one or more logical segment sequences, such as Figure 3 As shown, such as 4G-C to 10G.

[0044] Preferably, step S4 further includes: the interlocking system locks the reverse route according to the route allocation command. Figure 3 As shown, such as 4G-C to 10G.

[0045] Step S5: The communication train periodically applies to the interlocking system for requisition of the route according to the reverse running head code, for example, 4G-C-10G.

[0046] Step S6: The interlocking system sends a requisition permission to the train based on the requisition application of the communication train.

[0047] Step S7: After the communication train obtains the new reverse route, it controls the train to automatically change ends and provides the end change information to the interlocking system and ATS system. The ATS changes the display of the train active end on the dispatching interface according to the end change information.

[0048] Step S8: The communication train applies to the interlocking system for releasing the route used before the train changes ends, and the interlocking system releases the corresponding logic section locking state. For example, 6G.

[0049] Step S9: The communication train continues to run according to the head code running in the reverse direction, and the interlocking system completes the release and unlocking of the corresponding logical section based on the position passed by the communication list.

[0051] On the other hand, the present application also discloses: a train control system, the control system includes a data processing unit, and the data processing unit is configured to control the train operation according to the train arbitrary position return method described in Example 1.

[0052] The present invention provides a method for train reversal at any position and a control system thereof, which realizes that the train stops immediately and changes ends to run to the destination in the opposite direction by setting the reverse direction head code / plan, thereby improving the efficiency of the train reversal operation and ensuring the safety of operation.
