Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to a platform screen door control method, device, electronic equipment, and computer-readable storage medium. Background Technology

[0002] Platform screen doors are a crucial element of safe operation in urban rail transit, effectively preventing foreign objects and personnel from entering the track area and improving passenger safety and comfort while waiting for trains. In existing urban rail transit control systems, the interlocking subsystem opens and closes platform screen doors based on control information sent by the onboard subsystem, allowing passengers to board and alight through these doors. The linkage between platform screen doors and the signaling system plays a vital role in train control and passenger service. In fully automated operation mode, the elimination of the traditional driver results in significant differences in the linkage control between platform screen doors and the signaling system compared to manned operation, placing higher demands on the safety and reliability of both systems. Frequent changes in commands issued by the interlocking subsystem to the platform screen doors could disrupt their normal operation and pose certain safety risks.

Attached Figure Description

[0040] Figure 1 This is a flowchart illustrating an embodiment of a platform door control method according to the present invention;

[0041] Figure 2 This is a schematic diagram of an embodiment of a platform door control device according to the present invention;

[0042] Figure 3 This is a schematic diagram of an embodiment of an electronic device according to the present invention. Detailed Implementation

[0043] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0044] Figure 1 The diagram illustrates a flowchart of an embodiment of a platform screen door control method provided by the present invention, executed by an interlocking subsystem. Figure 1 As shown, it includes the following steps:

[0045] S1. When a target operation command is received, the legality of the target operation command is verified.

[0046] The target operation command is the operation command of any onboard subsystem to the target platform screen door. The interlocking subsystem connects to multiple onboard subsystems and can communicate with multiple onboard subsystems. One onboard subsystem connects to the platform rails of multiple natural stations. The platform rail is the track section where the platform screen door is located, and the platform rail of one natural station corresponds to multiple platform screen doors.

[0047] In S1, the step of validating the target operation command includes:

[0048] 1) When the target operation command includes a door opening command, determine whether the target operation command contains the door opening code of the target platform door; if yes, the target operation command is deemed to have passed the validity check; if no, the target operation command is deemed to have failed the validity check.

[0049] 2) When the target operation command includes a door closing command or a default command, determine whether the target operation command contains a zero door opening code for the target platform door; if yes, determine that the target operation command passes the validity check; if no, determine that the target operation command fails the validity check.

[0050] The target operation command can include a command type and a door opening code. Command types include: door opening command, door closing command, and default command. A default command refers to a command sent by the onboard subsystem to the interlocking subsystem when no command is sent, or when the command sent by the onboard subsystem is not a door opening or closing command, but a default value sent according to interface requirements. Different door opening codes correspond to different door opening relays. When the train formation, stopping point, and direction of travel are different, the number of platform doors that need to be opened on the same platform track will vary. The interlocking subsystem drives the corresponding door opening relay based on the received door opening code to open the correct position and number of platform doors.

[0051] It should be noted that if the door opening code in the received target operation command is not the door opening code of the platform door corresponding to the current platform rail, the target operation command will still be deemed to have failed the validity check.

[0052] S21. When the target operation command passes the validity check, determine whether the target operation command is inconsistent with the previous operation command of the target platform door to obtain a first judgment result, and determine whether the driving time of the previous operation command of the target operation command has reached the preset time to obtain a second judgment result.

[0053] The drive duration is defined as the time taken for the platform gate subsystem corresponding to the target platform gate to execute the operation command. This duration is counted from the start of the operation command execution. The preset duration is the minimum drive duration of the operation command, which can be pre-configured according to actual conditions (e.g., 5 seconds), and there is no limit set here.

[0054] S31. When both the first judgment result and the second judgment result are yes, control the platform door subsystem corresponding to the target platform door to execute the target operation command and start timing.

[0055] Specifically, when both the first and second judgment results are yes, the interlocking subsystem sends a target operation command to the platform screen door subsystem corresponding to the target platform screen door, and that platform screen door subsystem executes the target operation command. The timing begins when the interlocking subsystem sends the target operation command to the platform screen door subsystem corresponding to the target platform screen door. The purpose of the timing is to record the driving duration of the target operation command to determine whether subsequent operation commands can be executed.

[0056] In one alternative approach, it also includes:

[0057] S22. When the target operation command fails the validity check, disconnect the communication with any of the vehicle subsystems and output the fault information of the vehicle subsystem.

[0058] The types of fault information include: text-based fault alarm information, voice-based fault alarm information, and audible and visual fault alarm information. Fault information is sent to the corresponding monitoring terminal for fault handling.

[0059] In one alternative approach, it also includes:

[0060] Based on the platform door ID contained in the target operation command, the target platform door is determined from the platform doors configured in the interlocking subsystem.

[0061] The number and location of platform doors are determined based on the number of platform door IDs.

[0062] In one alternative approach, it also includes:

[0063] S32. When the first judgment result or the second judgment result is negative, the platform door subsystem corresponding to the target platform door is controlled not to execute the target operation command.

[0064] To better illustrate the technical solution of this embodiment, the platform door control scenario shown in Table 1 is used for explanation. Here, KMJ is the door opening relay, GMJ is the door closing relay, door opening code 1 corresponds to KMJ1, door opening code 2 corresponds to KMJ2, and T is the preset duration.

[0067]

[0068] The technical solution of this embodiment can avoid the security risks caused by frequent changes in commands, ensure the safe execution of platform door operation instructions, and improve the completeness and reliability of platform door control.

[0070] The verification module 210 is used to: when a target operation command is received, to perform a legality verification on the target operation command; wherein, the target operation command is: an operation command from any vehicle-mounted subsystem to the target platform door;

[0071] The judgment module 220 is used to: when the target operation command passes the legality verification, determine whether the target operation command is inconsistent with the previous operation command of the target platform door, obtain a first judgment result, and determine whether the driving time of the previous operation command of the target operation command has reached the preset time, obtain a second judgment result.

[0072] The first control module 230 is used to: when both the first judgment result and the second judgment result are yes, control the platform door subsystem corresponding to the target platform door to execute the target operation command and start timing.

[0073] In one alternative approach, a second control module is also included;

[0074] The second control module is used to: disconnect communication with any of the vehicle subsystems and output fault information of the vehicle subsystem when the target operation command fails the validity check.

[0075] In one optional embodiment, the step of validating the target operation command in the verification module 210 includes:

[0076] When the target operation command includes a door opening command, determine whether the target operation command contains the door opening code of the target platform door; if yes, the target operation command is determined to have passed the legality check; if no, the target operation command is determined to have failed the legality check.

[0077] When the target operation command includes a door closing command or a default command, determine whether the target operation command contains a zero door opening code for the target platform door; if yes, the target operation command is deemed to have passed the validity check; if no, the target operation command is deemed to have failed the validity check.

[0078] In one alternative approach, a preprocessing module is also included;

[0079] The preprocessing module is used to: determine the target platform door from the platform doors configured in the interlocking subsystem based on the platform door ID contained in the target operation command.

[0080] In one alternative approach, a third control module is also included;

[0081] The third control module is used to: control the platform door subsystem corresponding to the target platform door not to execute the target operation command when the first judgment result or the second judgment result is negative.
