The method includes a process where platform doors request train doors to perform alignment isolation, and a process where train doors request platform doors to perform alignment isolation. In both processes, given the alignment isolation code positions, the onboard controller identifies the side platform and then reverses the order of the isolation code positions of the train doors or platform doors, ensuring that the platform door alignment isolation code position matches the train door sequence number, or vice versa. Compared to existing technologies, this invention avoids the problems of unclear switching time and unclear switching maintenance time when switching alignment isolation information from an island platform to a side platform; it also avoids the problems of incomplete or erroneous execution of the alignment isolation function by the train or platform door system.

Description

Technical Field

[0001] This invention relates to a method for alignment isolation during the operation of rail transit trains, and more particularly to a method, apparatus, equipment, and medium for implementing alignment isolation on side platforms. Background Technology

[0002] With the development of rail transit technology, the level of automation in rail transit has gradually increased. International standards define four levels of Level of Automation (GOA) based on the degree of automation of rail transit lines, from GOA1 to GOA4, from lowest to highest. GOA4 represents fully automated driving, where train wake-up, hibernation, start-up, stopping, door opening and closing, and train operation in emergencies are all automated, requiring no human intervention. At this level, isolation after train and platform door malfunctions is entirely automated. However, on island and side platforms, a mismatch may occur between the platform door numbering definition and the train door numbering definition.

[0003] In the existing alignment isolation function, the on-board controller is only responsible for the one-to-one correspondence transmission of platform door and train door status signals between the platform door and the train, without adding any additional logic. This means that regardless of the driving mode or whether the train is positioned, the on-board controller will forward the code position.

[0004] When a train is operating in an island platform area, the platform screen doors and train door numbers correspond one-to-one. The onboard controller is only responsible for transmitting the one-to-one correspondence between the platform screen doors and the train's door status signals, without adding any extra logic. However, when operating in a side platform area, the first door number becomes equivalent to the last platform screen door number, resulting in a mismatch. Furthermore, the timing of the train and platform screen doors sending and initializing the alignment isolation signal also differs. There are issues with the switching time and duration of the alignment isolation information when switching from an island platform to a side platform, which cannot be simply done by reversing the code positions; logical judgment is required. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art by providing a method, device, equipment and medium for achieving side platform alignment and isolation.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] According to a first aspect of the present invention, a method for implementing side platform alignment isolation is provided, the method comprising a process of platform doors requiring train doors to perform alignment isolation and a process of train doors requiring platform doors to perform alignment isolation;

[0008] In both of the above processes, when the alignment isolation code is known, the on-board controller identifies the side platform and then reverses the order of the isolation codes of the train doors or platform doors, so that the alignment isolation code of the platform door matches the train door number or the alignment isolation code of the train door matches the platform door number.

[0009] As a preferred technical solution, the side platform has an identification number indicating that it is a side platform.

[0010] As a preferred technical solution, the method requires first defining the platform door and train door sequence numbers.

[0011] As a preferred technical solution, the method for defining the platform door sequence number is as follows: based on the train's direction of travel being forward, the left platform is defined as side A or left side, and numbered sequentially from front to back; the right platform is defined as side B or right side, and numbered in reverse order from front to back.

[0012] As a preferred technical solution, the method for defining the train door sequence number is as follows: based on the direction of the driver's cab 1 being forward, the left side is defined as side A, and the doors are numbered sequentially from front to back; the right side is defined as side B, and the doors are numbered in reverse order from front to back.

[0013] As a preferred technical solution, the driver's cab 1 is located at one end of the train, and the driver's cab 2 is located at the other end of the train.

[0014] As a preferred technical solution, the specific steps of the platform screen door requiring train doors to perform alignment and isolation are as follows:

[0015] Step 101: The central server issues the platform door alignment and isolation code.

[0016] Step 102: The vehicle controller determines whether the next station is a side platform and whether the platform door alignment isolation code has changed compared with the platform door alignment isolation code of the previous cycle. If both are yes, proceed to step 103; otherwise, return to step 101.

[0017] Step 103: The vehicle controller reverses the order of the platform door alignment isolation codes;

[0018] Step 104: The onboard controller determines whether the current station is a side platform and the train has not left the station and is in a stable state. If yes, return to step 103; otherwise, return to step 101.

[0019] As a preferred technical solution, in step 102, the vehicle controller determines the platform type by recognizing the identification number.

[0020] As a preferred technical solution, in step 104, when the train is in a stable state, a stability information is generated, and the on-board controller determines the train status based on the stability information.

[0021] As a preferred technical solution, the specific steps of the process requiring the platform doors to perform alignment and isolation are as follows:

[0022] Step 201: The train uploads the platform door alignment and isolation code.

[0023] Step 202: The on-board controller determines whether the next station is a side platform. If yes, proceed to step 203; otherwise, return to step 201.

[0024] Step 203: The on-board controller reverses the sequence of the train door alignment isolation codes;

[0025] Step 204: The on-board controller determines whether the current station is a side platform and the train has not left the station and is in a stable state. If yes, return to step 203; otherwise, return to step 201.

[0026] As a preferred technical solution, the method is applied to fully automated trains in rail transit.

[0027] According to a second aspect of the present invention, an apparatus for implementing side platform alignment isolation is provided, the apparatus comprising a platform door requiring vehicle door to perform alignment isolation module and a vehicle door requiring platform door to perform alignment isolation module;

[0028] When the alignment isolation code is known, the two modules mentioned above identify the isolation code sequence of the side platform and then reverse the sequence of the train door or platform door through the on-board controller, so that the platform door alignment isolation code matches the train door number or the train door alignment isolation code matches the platform door number.

[0029] As a preferred technical solution, the platform door requires the vehicle door to perform alignment and isolation module, which involves the central server issuing platform door alignment and isolation codes; the vehicle controller determining whether the next station is a side platform and whether the platform door alignment and isolation codes for the next station have changed compared to the previous cycle; and the vehicle controller reversing the order of the platform door alignment and isolation codes.

[0030] As a preferred technical solution, the platform door requires the platform door alignment isolation module to upload the platform door alignment isolation code through the train, determine whether the next station is a side platform through the on-board controller, and reverse the order of the train door alignment isolation code through the on-board controller.

[0031] According to a third 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.

[0032] According to a fourth 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.

[0033] Compared with the prior art, the present invention has the following advantages:

[0034] 1) This invention avoids the problems of unclear switching time and unclear switching duration when the alignment isolation information is switched from an island platform to a side platform;

[0035] 2) This invention avoids the problem of inadequate or erroneous execution of the alignment and isolation function of train or platform door systems. Attached Figure Description

[0037] Figure 2 This is a schematic diagram illustrating the definition of the train's double-door side and door sequence number according to the present invention;

[0038] Figure 3 This invention provides a flowchart illustrating the process by which platform screen doors require train doors to perform alignment and isolation.

[0039] Figure 4 This is a flowchart illustrating the process of trains requiring platform screen doors to perform alignment and isolation according to the present invention. Detailed Implementation

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0041] This invention proposes a method for implementing alignment isolation on side platforms. This method involves automatically reversing and switching alignment isolation codes within the side platform area. It is applied to fully automated driving trains (GOA4) in rail transit. GOA4 represents the highest level of fully automated driving, where isolation after train and platform door failures is entirely automated. Rail transit platforms include island platforms and side platforms. Different types of platforms have identification numbers indicating their type, which the onboard controller can use to determine the platform type. When the train is stationary, it generates station stabilization information, which the onboard controller uses to determine the train's status.

[0042] This invention utilizes an on-board controller to define the opening side and door sequence number of the side platform doors and the train, and is used to handle two situations: the platform door requires the train door to perform alignment isolation and the train requires the platform door to perform alignment isolation. When the alignment isolation code position is known, the on-board controller determines the platform type and reverses the order of the isolation code positions of the train door or the platform door.

[0043] like Figure 1 As shown, the method for defining the platform door opening side and door sequence number is as follows: based on the train's direction of travel being forward, the left platform is defined as side A or left side, and numbered sequentially from front to back; the right platform is defined as side B or right side, and numbered in reverse order from front to back.

[0044] like Figure 2 As shown, there is a driver's cab at each end of the train, designated as Driver's Cab 1 and Driver's Cab 2. The method for defining the train's door opening side and door sequence number is as follows: based on the direction of Driver's Cab 1 being forward, the left side is defined as side A, and numbered sequentially from front to back; the right side is defined as side B, and numbered in reverse order from front to back.

[0045] like Figure 3 As shown, when a platform screen door requests alignment isolation from a train door, the system determines the change in the alignment isolation code sent by the platform screen door and whether the next station is a side platform. This activates the onboard system's function to invert the code, ensuring the platform screen door's alignment isolation code matches the train door's sequence number. The specific steps are as follows:

[0046] Step 101: The center issues the platform door alignment and isolation code.

[0047] Step 102: The vehicle controller determines whether the next station is a side platform and whether the platform door alignment isolation code of the next station has changed compared with the platform door alignment isolation code of the previous cycle. If both are yes, proceed to step 103; otherwise, return to step 101.

[0048] Step 103: The vehicle controller reverses the order of the platform door alignment isolation codes;

[0049] Step 104: The on-board controller determines whether the current station is a side platform and the train has not left the station and is in a stable state. If yes, proceed to step 103; otherwise, return to step 101.

[0050] like Figure 4 As shown, when a train requests platform screen doors to perform alignment isolation, the system determines whether the next station is a side platform and activates the function of reversing the code position, so that the train's alignment isolation code position matches the platform screen door number. The specific steps are as follows:

[0051] Step 201: The train uploads the platform door alignment and isolation code.

[0052] Step 202: The on-board controller determines whether the next station is a side platform. If yes, proceed to step 203; otherwise, return to step 201.

[0053] Step 203: The on-board controller reverses the sequence of the train door alignment isolation codes;

[0054] Step 204: The on-board controller determines whether the current station is a side platform and the train has not left the station and is in a stable state. If yes, proceed to step 203; otherwise, return to step 201.

[0055] The method proposed in this invention has been verified on Shenzhen Metro Line 16.

[0056] The above is an introduction to the method embodiments. The following describes the solution of the present invention further through device embodiments.

[0057] The present invention provides a device for implementing side platform alignment isolation, the device comprising a platform door requiring vehicle door to perform alignment isolation module and a vehicle door requiring platform door to perform alignment isolation module;

[0058] When the alignment isolation code is known, the two modules mentioned above identify the isolation code sequence of the side platform and then reverse the sequence of the train door or platform door through the on-board controller, so that the platform door alignment isolation code matches the train door number or the train door alignment isolation code matches the platform door number.

[0059] The platform door requires the vehicle door to perform alignment and isolation module, which issues the platform door alignment and isolation code through the central server; determines whether the next station is a side platform through the vehicle controller, and whether the platform door alignment and isolation code of the next station has changed compared with the platform door alignment and isolation code of the previous cycle; and reverses the order of the platform door alignment and isolation codes through the vehicle controller.
