Description

TECHNICAL FIELD

[0001] The present application relates to the coupling and uncoupling of trains, and in particular to a test pulling authorization area division method based on train coupling and uncoupling, a device and a medium. BACKGROUND

[0002] Urban rail transit presents a tidal distribution of daily passenger flow, and uses the coupling / uncoupling function to improve user travel efficiency. In order to check the coupling state of the vehicle, test pulling is performed before coupling to prevent the vehicle from uncoupling during propulsion or traction running, which may cause serious consequences.

[0003] The test pulling process is as follows: after the mechanical coupler is successfully coupled, the ATS sends a test pulling instruction to the train in the decoupling mode, the train VOBC sends a test pulling request to the ZC, the ZC checks the relevant conditions and feeds back the authorization test pulling to the VOBC, and the VOBC executes the test pulling operation process after receiving the feedback.

[0004] After searching the Chinese patent publication No. CN113844506A, a train automatic test pulling method and device are disclosed, which specifically discloses that the method includes: receiving a test pulling command sent by an ATS system; in response to the test pulling command, sending test pulling locking information to a target area controller, so that the target area controller sends first information indicating that test pulling is allowed to a vehicle-mounted controller of a first train under the condition that test pulling conditions are met; after receiving the first information sent by the target area controller, controlling the first train to perform test pulling; and determining the result of the test pulling based on state information of the first train in the test pulling process. However, the existing patent does not accurately divide the test pulling area.

[0005] Therefore, in the process of currently performing test pulling operation, the area division is not accurate, which has adverse effects on train safety, economy, efficiency and the like, and becomes a technical problem to be solved. SUMMARY

[0006] The purpose of the present application is to overcome the defects of the prior art and provide a test pulling authorization area division method based on train coupling and uncoupling, a device and a medium.

[0007] The purpose of the present application can be achieved by the following technical solutions:

[0008] According to a first aspect of the present application, a test pulling authorization area division method based on train coupling and uncoupling is provided, which includes the following steps:

[0009] Step 1: when the coupling and uncoupling area D2 is configured with a test pulling function, the service stop point P of the coupling and uncoupling area D2 is taken as a search starting point for generating a test pulling authorization area D1;

[0010] Step 2, for the uplink service parking point P, the start position of the trial pull authorization area D1 is the position after extending the length l1 from the service parking point P upstream, and the end position of the trial pull authorization area D1 is the position after extending the length l2 from the service parking point P upstream, and the trial pull authorization area D1 is generated in the downlink direction;

[0011] Step 3, for the downlink service parking point P, the end position of the trial pull authorization area D1 is the position after extending the length l1 from the service parking point P downstream, and the start position of the trial pull authorization area D1 is the position after extending the length l2 from the service parking point P downstream, and the trial pull authorization area D1 is generated in the uplink direction;

[0012] Step 4, delete the trial pull authorization area that does not meet the condition.

[0013] As a preferred technical solution, the coupling and uncoupling area D2 is located on the platform, the turning track or the storage track.

[0014] As a preferred technical solution, the coupling and uncoupling area D2 has a coupled train and a decoupled train.

[0015] As a preferred technical solution, the service parking point screening manner specifically comprises: traversing each service parking point P in the coupling and uncoupling area D2, and screening all service parking points P.

[0016] As a preferred technical solution, the service parking point P is a coupling service parking point or an uncoupling service parking point.

[0017] As a preferred technical solution, the service parking point P is an overlap of different types of service parking points.

[0018] As a preferred technical solution, the length l1 is the maximum target coupling and uncoupling length of the service parking point P + the parking accuracy of the coupled train + the maximum trial pull distance; and the length l2 is the coupling and uncoupling length of the coupled train at the service parking point P - (the hook compression distance + the distance moved after the coupled train is collided during normal coupling + the coupled train parking error).

[0019] As a preferred technical solution, the coupled train parking error is used to control the parking range when starting to send the coupled request, the maximum trial pull distance is used to trigger emergency braking and parking and exit the trial pull when the decoupled train displacement exceeds the distance, and the distance moved after the coupled train is collided during normal coupling is used to prevent the coupled train from failing to decouple during coupling.

[0020] As a preferred technical solution, the trial pull authorization area that does not meet the condition in step 4 is a trial pull authorization area that is partially or completely absent in the coupling and uncoupling area D2.

[0021] As a preferred technical scheme, when the connecting and uncoupling area D2 is not configured with the trial pulling function, the vehicle-mounted controller directly controls the electric hook to extend after the mechanical hook state changes.

[0022] According to a second aspect of the present application, an electronic device is provided, comprising a memory and a processor, the memory storing a computer program, and the processor implementing the method when executing the program.

[0023] According to a third aspect of the present application, a computer readable storage medium is provided, storing a computer program, and the program is executed by a processor to implement the method.

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0032] As Figure 1As shown, this invention proposes a method for dividing the test pull authorization area based on train coupling and uncoupling, applied to the CBTC signaling system. It aims to quickly and reasonably determine the length of the test pull authorization area based on factors such as train length, test pull length, stopping accuracy of the coupled train, coupler compression distance, and the distance the coupled train moves after a collision during normal coupling. This method aims to improve train throughput by considering safety, economy, and efficiency. Specifically, it includes the following steps:

[0033] Step S1: Both the coupled train and the train to be coupled are located within the coupling / uncoupling area. When the project is configured with a test pull function, the service parking point within the coupling / uncoupling area is used as the search starting point. Searches are performed upstream and downstream according to the direction of the service parking point to generate the test pull authorization area. Service parking points can overlap, as long as they contain different attributes, such as service parking point type. In coupling / uncoupling areas without this function, the onboard system directly controls the electric coupler to extend after the mechanical coupler status changes.

[0034] Step S2: As Figure 2 As shown, for the upstream service stop, the upstream extension length to the service stop is: the maximum target coupling length of the service stop + the stopping accuracy of the coupled train + the maximum test pull distance, corresponding to the beginning of the test pull area. The upstream extension length to the service stop is: the coupling length of the service stop - (coupler compression distance + distance moved by the coupled train after collision during normal coupling + coupling stopping error), corresponding to the end of the test pull area.

[0035] The stopping error of the coupled train is used to control the stopping range when the coupling request is first sent. The maximum test pull distance is used to immediately trigger emergency braking and stop the train from attempting coupling if its displacement exceeds this distance. The distance the coupled train moves after a collision during normal coupling is used to prevent the coupled train from canceling its coupling request after leaving the coupling area, causing the ZC to cancel the decoupling authorization and resulting in the decoupling train mistakenly judging the decoupling as failed.

[0036] Step S3: As Figure 3 As shown, for the downstream service stop, the downstream extension length is: the maximum target coupling length of the service stop + the coupling stopping error + the maximum test pull distance, corresponding to the end of the test pull area. The downstream extension length is: the coupling train length of the service stop - (coupler compression distance + distance moved by the coupled train after collision during normal coupling + coupling stopping error), corresponding to the beginning of the test pull area.

[0037] Step S4: Delete the trial pull authorization areas that do not meet the conditions, that is, trial pull authorization areas that are partially or completely absent from the linked unlinking area.

[0038] The application has been applied in practice, and the division of the authorized area of the trial pulling improves the precision of the train coupling and uncoupling.
