Description

Background Art

[0002] Platform doors are one of the important guarantees for the safe operation of urban rail transit. They effectively prevent foreign objects and people from intruding into the track area and improve the safety and comfort of passengers waiting for the train. In the existing urban rail transit control system, the interlocking subsystem can open and close the platform doors according to the platform door control information sent by the on-board subsystem, and passengers can get on and off the train through the platform doors. The linkage between the platform door and the signal system plays a vital role in driving control and passenger boarding and alighting services. In the fully automatic operation mode, since the traditional driver is cancelled on the train, the linkage control of the platform door and the signal system is quite different from that in the manned driving mode, which puts higher requirements on the safety and reliability of the platform door and the signal system. If the commands issued by the interlocking subsystem to the platform door change frequently, it may affect the normal operation of the platform door and there is a certain safety risk.

[0042] Figure 3 The figure is a schematic structural diagram of an embodiment of an electronic device of the present invention. DETAILED DESCRIPTION

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

[0044] Figure 1 FIG. 2 is a flow chart showing an embodiment of a platform door control method provided by the present invention, which is executed by the interlocking subsystem. Figure 1 As shown, the following steps are included:

[0045] S1. When a target operation command is received, a validity check is performed on the target operation command.

[0046] The target operation command is: an operation command of any onboard subsystem to the target platform door. The interlocking subsystem connects multiple onboard subsystems and can communicate with multiple onboard subsystems. One onboard subsystem connects the platform rails of multiple natural stations. The platform rails are the track sections where the platform doors are located. The platform rails of one natural station correspond to multiple platform doors.

[0047] In S1, the step of performing a legality check on the target operation command includes:

[0048] 1) When the target operation command includes a door opening command, determine whether the target operation command includes the door opening code of the target platform door; if so, determine that the target operation command passes the legality check; if not, determine that the target operation command fails the legality check.

[0049] 2) When the target operation command includes a door closing command or a default command, determine whether the target operation command includes a door opening code of the target platform door which is zero; if so, determine that the target operation command has passed the legality check; if not, determine that the target operation command has not passed the legality check.

[0050] Among them, the target operation command can include a command type and a door opening code. The command types include: door opening command, door closing command and default command. The default command means that the onboard subsystem has not sent a command to the interlocking subsystem, or the command sent by the onboard subsystem is not a door opening command or a door closing command. It is the default value sent according to the interface requirements. Different door opening codes correspond to different door opening relays. When the train formation, parking point, and running direction are different, the number of platform doors that need to be opened on the same platform track is different. The interlocking subsystem drives the corresponding door opening relay according to 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 track, it is still determined that the target operation command has not passed the legality check.

[0052] S21. When the target operation command passes the legality check, determine whether the target operation command is inconsistent with the previous operation command of the target 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 a preset time, obtain a second judgment result.

[0053] The driving duration is: the timing duration of the platform door subsystem corresponding to the target platform door to execute the operation command, which is counted from the start of the operation command. The preset duration is the shortest driving duration of the operation command, which can be pre-configured according to actual conditions (such as 5s), and there is no limit 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] Wherein, when both the first judgment result and the second judgment result are yes, the interlocking subsystem sends a target operation command to the platform door subsystem corresponding to the target platform door, and the platform door subsystem executes the target operation command. The timing starts when the interlocking subsystem sends the target operation command to the platform door subsystem corresponding to the target platform door. The purpose of the timing is to record the driving duration of the target operation command, so as to determine whether the subsequent operation command can be executed.

[0056] In an optional manner, the method further includes:

[0057] S22: When the target operation command fails to pass the legality check, disconnect the communication with any vehicle-mounted subsystem and output the fault information of the vehicle-mounted subsystem.

[0058] The types of fault information include: fault alarm information in text form, fault alarm information in voice form, fault alarm information in sound and light form, etc. The fault information is sent to the corresponding monitoring terminal for fault processing.

[0059] In an optional manner, the method further includes:

[0060] According to the platform door ID included in the target operation command, the target platform door is determined from the platform doors configured by the interlocking subsystem.

[0061] Among them, the number and positions of the platform doors are determined according to the number of platform door IDs.

[0062] In an optional manner, the method further includes:

[0063] S32: When the first judgment result or the second judgment result is no, controlling the platform door subsystem corresponding to the target platform door 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 illustration. KMJ is a door opening relay, GMJ is a door closing relay, door opening code 1 corresponds to KMJ1, door opening code 2 corresponds to KMJ2, and T is a preset duration.

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

[0073] In an optional manner, it further includes: a second control module;

[0077] When the target operation command includes a door closing command or a default command, determine whether the target operation command includes a door opening code of the target platform door which is zero; if so, determine that the target operation command has passed the legality check; if not, determine that the target operation command has not passed the legality check.

[0078] In an optional manner, it further includes: a preprocessing module;
