Description

Technical Field

[0001] This invention relates to rail transit signal control systems, and in particular to a method, device, and medium for managing the coupling and uncoupling status. Background Technology

[0002] In the field of rail transit, the uneven distribution of passenger flow in space and time has led to the development of flexible train formation technology. This technology allows for dynamic increases or decreases in transport capacity based on predicted passenger flow changes through train coupling and decoupling, significantly improving transport efficiency and operational effectiveness. In the general coupling process, one train unit is stationary, called the coupled train; another train unit collidees with the coupled train at a lower speed, called the decoupling train. After the collision, if the coupler is in normal condition, the coupling is complete, and the two train units are combined into a single train formation for normal operation. After the coupler collision, some projects require a test pull, where the decoupling train reverses its direction to apply force to the coupler to check for a secure connection. The general decoupling process involves disconnecting the coupler between two train units while the train is stationary, creating two independent train units, each operating as a separate train formation. This process is quite complex and cumbersome, and the safety of the coupling and uncoupling process is extremely important. If there is a safety problem in this process, at best the coupling and uncoupling cannot be completed in time, affecting operations, and at worst the improper protection during coupling and uncoupling can cause harm to passengers.

[0003] A search of Chinese Patent Publication No. CN112061140A reveals an online train coupling and uncoupling method, capable of coupling and uncoupling trains on the running line at any location and time during operation, offering high flexibility and adaptability to various scenarios. However, the coupling and uncoupling process of this existing patent is relatively complex; therefore, simplifying the coupling and uncoupling process becomes a technical problem that needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a method, device and medium for managing the connection and disconnection status that is easy to implement, highly secure and easy to expand and maintain.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] According to a first aspect of the present invention, a coupling and uncoupling state management method is provided, which simplifies the coupling and uncoupling process into the switching of five states and performs state transitions under the premise of ensuring train safety. The method includes a decoupling process, a coupling process, and a coupling and uncoupling process.

[0007] The five states include CS0_DEFAULT, CS1_GOING_COUPLE, CS2_BE_COUPLE, CS3_TRAIL_HUAL, and CS4_RELOAD.

[0008] As a preferred technical solution, the CS0_DEFAULT state is the default state of the train.

[0009] As a preferred technical solution, the CS1_GOING_COUPLE state is the state when the train is decoupling.

[0010] As a preferred technical solution, the CS2_BE_COUPLE state is the state when the train is coupled together.

[0011] As a preferred technical solution, the CS3_TRAIL_HUAL state is the state during the train test run.

[0012] As a preferred technical solution, the CS4_RELOAD state is the state when the train loads data.

[0013] As a preferred technical solution, the de-linking process specifically includes the following steps:

[0014] Step S1: The dispatcher sends a ReqGoCouple request to the train to be coupled via the Automatic Train Monitoring System (ATS).

[0015] Step S2: After receiving the request from the Automatic Train Monitoring System (ATS), the decoupled train checks whether the coupler alignment status is normal. If so, the train status is switched from CS0_DEFAULT to CS1_GOING_COUPLE; otherwise, the train status is switched back to CS0_DEFAULT, and an alarm is triggered according to the specific reason.

[0016] Step S3: Monitor the change in the status of the decoupling train's head coupler. If the change in the coupler status is normal, switch the status of the decoupling train from CS1_GOING_COUPLE to CS3_TRAIL_HUAL. Otherwise, check whether the decoupling has been canceled or if there are other abnormal decoupling situations. If so, switch the train status to CS0_DEFAULT and issue an alarm according to the specific reason. Otherwise, keep the status unchanged and continue checking.

[0017] Step S4: Check if a test pull operation is required on the coupled car. If not, switch the status to CS4_RELOAD. If it is required, check if there is a problem with the test pull status. If there is a problem, switch the train status to CS0_DEFAULT and issue an alarm according to the specific reason. Otherwise, check if the coupling has been completed. If so, switch the status to CS4_RELOAD. Otherwise, keep the status unchanged and continue checking.

[0018] As a preferred technical solution, in step S4, if the status is changed to CS4_RELOAD, the train checks whether the new data loading after coupling has been correctly completed. If so, the status is changed from CS4_RELOAD to CS0_DEFAULT; otherwise, the train status is changed to CS0_DEFAULT, and an alarm is triggered according to the specific reason.

[0019] As a preferred technical solution, the connection process specifically includes:

[0020] Step S5: The dispatcher sends a coupling request (ReqBeCouple) to the coupled train through the Automatic Train Monitoring System (ATS).

[0021] Step S6: After receiving the request from the Automatic Train Monitoring System (ATS), the coupled train checks whether its own conditions meet the safety conditions for coupling. If all conditions are met, the train's status is switched from CS0_DEFAULT to CS2_BE_COUPLE. Otherwise, the train's status is switched to CS0_DEFAULT, and an alarm is triggered according to the specific reason.

[0022] Step S7: Monitor whether the coupled train has completed the coupling. If it has, switch the status from CS2_BE_COUPLE to CS4_RELOAD. Otherwise, check whether the coupling has been cancelled or if there is an abnormality. If so, switch the train status to CS0_DEFAULT and issue an alarm according to the specific reason. Otherwise, keep the status unchanged and continue checking.

[0023] As a preferred technical solution, the safety conditions for coupling in step S6 include coupler alignment, no overlap in the prohibited coupling areas, train doors being closed and locked, and the train coming to a safe stop.

[0024] As a preferred technical solution, the grouping and degrouping process specifically includes:

[0025] Step S8: The dispatcher sends a decoupling request (ReqDecouple) to the train formation via the Automatic Train Monitoring System (ATS).

[0026] Step S9: After receiving the ReqDecouple request from the Automatic Train Monitoring System (ATS), the train in the formation checks whether the current train in the formation is in the CS0_DEFAULT state and has been properly uncoupled. If so, the train checks whether the new data after coupling has been correctly loaded. If so, the state is switched from CS4_RELOAD to CS0_DEFAULT. Otherwise, the train state is switched to CS0_DEFAULT, and an alarm is triggered according to the specific reason.

[0027] According to a second aspect of the present invention, an electronic device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the program to implement the method described thereon.

[0028] According to a third aspect of the present invention, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the method described thereon.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] 1) This invention simplifies the complex process of connecting and disconnecting into a switching of 5 states, making the process simple, easy to understand and implement;

[0031] 2) This invention performs state transitions while ensuring train safety, and promptly alerts trains to any problems, greatly improving safety;

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0037] First refer to Figure 1 The main process method of this invention is described, including the following steps:

[0038] Step S0: The dispatcher sends a ReqGoCouple request to the train to be coupled via the Automatic Train Monitoring System (ATS).

[0039] Step S1: After receiving a request from the Automatic Train Monitoring System (ATS), the train to be coupled checks whether the coupler alignment is normal. If so, the train's status is switched from CS0_DEFAULT to CS1_GOING_COUPLE. Otherwise, proceed to step S8.

[0040] Step S2: Monitor the status changes of the train head coupler of the decoupling train. If the coupler status changes are normal, that is, the train coupler has been correctly engaged, then switch the status of the decoupling train from CS1_GOING_COUPLE to CS3_TRAIL_HUAL. Otherwise, check whether decoupling has been cancelled or if there are other decoupling anomalies. Other decoupling anomalies include loss of decoupling train coupler alignment status or the trackside area controller ZC prohibiting decoupling. If so, proceed to step S8 for processing; otherwise, keep the status unchanged and continue checking.

[0041] Step S3: Check the trailer to see if a test pull is needed. If not, switch the status to CS4_RELOAD. If so, check if there are any problems with the test pull status, i.e., whether the coupler disconnects when pulled in the reverse direction after impact. If there is a problem, proceed to step S8. Otherwise, check if the coupling is complete, specifically whether the coupler remains in the coupled state after the test pull. If so, switch the status to CS4_RELOAD and proceed to step S7. Otherwise, keep the status unchanged and continue checking.

[0042] refer to Figure 2 The main process method of this invention is described, including the following steps:

[0043] Step S4: The dispatcher sends a coupling request (ReqBeCouple) to the coupled train through the Automatic Train Monitoring System (ATS).

[0044] Step S5: After receiving the request from the Automatic Train Monitoring System (ATS), the coupled train checks whether its own conditions meet the safety conditions for coupling, specifically: coupler alignment, no intersection with the prohibited coupling zone, doors closed and locked, and the train safely stopped. If these conditions are met, the train's status is switched from CS0_DEFAULT to CS2_BE_COUPLE. If not, proceed to step S8 for further processing.

[0045] Step S6: Monitor whether the coupling of the coupled train is completed, i.e., the coupling of the coupled car coupler is normal and the train is safely stopped. If it is completed, switch the state from CS2_BE_COUPLE to CS4_RELOAD. Otherwise, check whether the coupling has been cancelled or there is an abnormality. The specific abnormality is that the trackside area controller ZC prohibits the coupling, or the coupled car requests the trackside area controller ZC to cancel the coupling state and the timeout occurs. If so, proceed to step S8 for processing. Otherwise, the state remains unchanged and the check continues.

[0046] Step S7: Check if the new data loading after coupling has been completed correctly. If so, switch the status from CS4_RELOAD to CS0_DEFAULT; otherwise, proceed to step S8.

[0047] Step S8: Switch the train status to CS0_DEFAULT and trigger an alarm based on the specific reason.

[0048] refer to Figure 3 The main process method of this invention is described, including the following steps:

[0049] Step S9: The dispatcher sends a decoupling request (ReqDecouple) to the train formation via the Automatic Train Monitoring System (ATS).

[0050] Step S10: After receiving the ReqDecouple request from the Automatic Train Monitoring System (ATS), the train sets up a train and checks whether the current train set is in the CS0_DEFAULT state and has been properly uncoupled. If so, proceed to step S7; otherwise, proceed to step S8.
