[0023] Embodiment:

[0024] As Figure 1 shown, a platform door opening and closing system based on a full electronic interlock, powered by a power supply, includes:

[0025] A platform door opening and closing box, and the platform door opening and closing knob 1 of the platform door opening and closing box outputs an opening or closing request message.

[0026] A distribution cabinet 2, which is arranged between the platform door opening and closing box and the full electronic interlock for circuit protection and isolation; the distribution cabinet is a lightning protection distribution cabinet.

[0027] A full electronic interlock 3, which receives the request message from the platform door opening and closing box and sends the request message to the vehicle-mounted controller through the vehicle-ground communication link, and at the same time sends the opening or closing instruction message received from the vehicle-mounted controller through the vehicle-ground communication link to the platform door 5.

[0028] A vehicle-mounted controller 4, which receives the instruction message and judges whether the train stops accurately. If the train stops accurately, it sends an opening message through the vehicle-ground communication link.

[0029] As Figure 2As shown, the platform screen door opening and closing box includes a platform opening and closing knob, a green opening indicator light, and a yellow closing indicator light. When the platform opening and closing knob is on the opening side, it outputs an opening request message, and at the same time, the green opening indicator light is lit. When the platform opening and closing knob is in the closing position, it outputs a closing request message, and at the same time, the yellow closing indicator light is lit.

[0030] The platform screen door system based on the all - electronic interlocking also includes an opening circuit and a closing circuit. When the platform opening and closing knob outputs an opening request message, it is connected to the opening circuit, and the opening circuit is connected to the all - electronic interlocking to output an opening instruction. When the opening knob outputs a closing request message, it is connected to the closing circuit, and the opening circuit is connected to the all - electronic interlocking to output a closing instruction.

[0031] The all - electronic interlocking collects the opening or closing information through the acquisition unit EIB board.

[0032] Specifically, as Figure 3 shown, the circuit for collecting the state of the platform opening and closing knob includes a switch cabinet, an interlocking cabinet, a lightning protection distribution cabinet, and a local control panel. There is a 24V power supply in the switch cabinet, an all - electronic interlocking in the interlocking cabinet, and the local control panel is installed in the platform screen door opening and closing box. When the platform opening and closing box knob is operated to the "opening" position, the contacts (1(7) / 3(9) / 5(11) equivalent) of the platform opening and closing knob (ZTKGMA) connect to the nodes (8 / 10 / 12), and the 24V power supply (KGLZ24, KGLF24) is introduced into the platform opening circuit (ZTKMA +, ZTKMA -) to form a closed loop. The acquisition unit EIB board of the all - electronic interlocking A / B system collects the opening state, and the opening state is sent to the on - vehicle controller through the vehicle - ground communication link. After the on - vehicle controller determines that the train has stopped accurately, it forwards the opening command to the platform screen door through the vehicle - ground communication link by the interlocking, and the platform screen door is opened while the train door is opened.

[0033] When the platform opening and closing box knob is operated to the "closing" position, the contacts (1(7) / 3(9) / 5(11) equivalent) of the platform opening and closing knob (ZTKGMA) connect to the nodes (2 / 4 / 6), and the 24V power supply (KGLZ24, KGLF24) is introduced into the platform closing circuit (ZTGMA +, ZTGMA -) to form a closed loop. The acquisition unit EIB board of the all - electronic interlocking A / B system collects the closing state, and the closing state is sent to the on - vehicle controller through the vehicle - ground communication link. After the on - vehicle controller determines that the train has stopped accurately, it forwards the closing command to the platform screen door through the vehicle - ground communication link by the interlocking, and the platform screen door is closed while the train door is closed.

[0034] Operate the platform box knob to the "zero position". The contacts of the platform door opening / closing knob (ZTKGMA) (equivalent to 1(7) / 3(9) / 5(11)) connect to node (0). Since the acquisition circuit closed loop cannot be formed, the EIB board of the full electronic interlock A / B system acquisition unit cannot collect the status information and does not send it to the vehicle controller.

[0035] A platform door opening / closing based on full electronic interlock. Based on the platform door opening / closing system based on full electronic interlock as Figure 4 shown, it includes the following steps:

[0036] Step 1: Collect the status of the platform door opening / closing knob of the platform door opening / closing box, and judge whether the status of the platform door opening / closing knob is in the opening gear or the closing gear. If it is in the opening gear, jump to Step 2; if it is in the closing gear, jump to Step 3.

[0037] Step 2: The full electronic interlock receives the opening request information of the platform door opening / closing box and sends it to the vehicle controller through the vehicle-ground communication link; after the vehicle controller judges that the train has stopped accurately, it sends the opening command to the full electronic interlock through the vehicle-ground communication link, and the full electronic interlock forwards the opening command to the platform door, and the platform door opens.

[0038] Step 3: The full electronic interlock receives the closing request information of the platform door opening / closing box and sends it to the vehicle controller through the vehicle-ground communication link; after the vehicle controller judges that the train has stopped accurately, it sends the closing command to the full electronic interlock through the vehicle-ground communication link, and the full electronic interlock forwards the closing command to the platform door, and the platform door closes.

[0039] The status of the platform door opening / closing knob also includes the zero position gear. In Step 1, if the status of the platform door opening / closing knob is in the zero position gear, the full electronic interlock does not send the status of the platform door opening / closing knob to the vehicle controller.

[0040] Through the full electronic interlock of the present utility model, the information of requesting to open or close the door of the platform door can be sent to the vehicle controller. The vehicle controller judges whether to permit opening or closing according to whether the train has stopped accurately. Compared with the existing technical solutions for opening or closing the door, the method of this solution is more convenient for handling the faults of clamping people or objects between the car door and the platform door in the FAM mode. Operating the platform door opening / closing box to control the car door and the platform door improves the fault handling efficiency, and at the same time avoids the potential safety hazards brought by remote control fault handling.

[0041] After considering the specification and the implemented embodiments disclosed herein, those skilled in the art will easily think of other implementation embodiments of this application. This application aims to cover any variations, uses, or adaptable changes of this application. These variations, uses, or adaptable changes follow the general principles of this application and include the common general knowledge or conventional technical means in the technical field not disclosed in this application.

[0042] It should be understood that the present application is not limited to the exact structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present application is only limited by the appended claims.
