[0002] Currently, the control of devices such as platform doors of high-speed maglev trains mainly comes from the control of the wireless system. Although the long-distance transmission of the wireless system is generally reliable, it cannot guarantee the reliability of the wireless system under certain extreme conditions. Therefore, when the wireless system fails to control the platform devices after the vehicle arrives at the station, how to adopt an effective control device to ensure the transmission control of the linkage signal between the platform door and the car door is a technical problem that those skilled in the art need to solve currently.

The car door detection module is communicatively connected to the platform door control module and is used to be installed on the platform to detect whether the car door is in the open state.

[0011] In some embodiments, the platform door control module includes:

[0015] A control unit, communicatively connected to the processing unit, is configured to control the opening of the platform door after receiving the door execution opening signal and the door confirmation opening signal.

[0016] In some embodiments, the door detection module is a distance detection module. The distance detection module has a preset inclination angle with respect to the plane where the guide rail is located. The distance detection module is configured to emit detection light towards the door to detect whether the door is in an open state.

[0017] In some embodiments, the number of the distance detection modules is at least two, and the length of the array formed by the at least two distance detection modules is not less than the width of the door.

[0018] In some embodiments, the triggering module is a triggering circuit, and the triggering circuit includes:

[0019] A triggering gasket, disposed on the surface of the guide rail, is configured to contact the skid;

[0020] A circuit body, built into the guide rail and connected to the triggering gasket and the door control module, is configured to generate a triggering signal;

[0021] A power supply unit, connected to the circuit body, is configured to supply power to the circuit body.

[0022] In some embodiments, the triggering module is a triggering sensor, and the triggering sensor includes an induction contact. The surface of the induction contact is flush with the surface of the guide rail. The triggering sensor is configured to generate a triggering signal when the induction contact contacts the skid.

[0023] In some embodiments, two sets of triggering modules are provided. The skid includes two sets of conductive contacts. The distance between the two sets of conductive contacts is equal to the distance between the two sets of triggering modules, so that triggering signals are generated when the two sets of conductive contacts contact the two sets of triggering modules respectively.

[0024] In some embodiments, the platform door and door linkage control device further includes a prompting module. The prompting module is configured to be installed on the platform door to emit a prompting sound and / or light when the platform door is opened or closed.

[0043] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0044] In order to enable those skilled in the art of this technology to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0045] It should be noted that the orientation terms such as "upper end, lower end, left side, right side" described below are defined based on the accompanying drawings of the specification.

[0046] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 which is a schematic structural diagram of the first platform door and door linkage control device in the embodiment of the present application; Figure 2 which is a schematic structural diagram of the second platform door and door linkage control device in the embodiment of the present application; Figure 3 is Figure 1 the platform door control block diagram of the platform door and door linkage control device shown.

[0047] The platform door and door linkage control device provided by the embodiment of the present application includes a guide rail 10, a sled 20, a trigger module, a door control module 50, and a platform door control module 60.

[0048] The high-speed maglev vehicle is equipped with a skid 20, which is arranged on a vehicle suspension frame 30 and faces the guide rail 10. The skid 20 is used for supporting and sliding the rail vehicle to reduce speed, etc. The material used by the skid 20 is conductive.

[0049] The trigger module is arranged on the guide rail 10, and is used to contact the sled 20 when the vehicle lands to generate a trigger signal. When the vehicle reaches the designated position, the vehicle lands, and the sled 20 of the vehicle after landing contacts the trigger module, so that the trigger module is triggered to generate a trigger signal.

[0050] The door control module 50 is connected to the trigger module for communication, and is used to receive the trigger signal to control the opening of the door 80. For example, the door control module 50 can be a door controller, and when the door controller receives the trigger signal fed back by the trigger module, it can issue a door opening command to achieve the purpose of opening the door 80.

[0051] The platform door control module 60 is connected to the vehicle door control module 50 for communication. The platform door control module 60 is used to control the platform door 91 to open after the vehicle door 80 is opened. For example, the platform door control module 60 may be a platform door controller. After the vehicle door 80 is opened, the platform door controller may issue a platform door opening command to open the platform door 91.

[0052] It should be noted that the design of the platform door 91 (also called a screen door or a safety door) opening after the car door 80 is opened is to ensure the safety of passengers and improve the operational efficiency of the platform 90. Specifically, it includes: first, ensuring that passengers can enter the car only after the train stops and the car door 80 opens, so as to prevent passengers from entering the car when the train is not completely stopped or the car door 80 is not completely opened, thereby avoiding possible accidents; second, if the platform door 91 opens before the car door 80, the passengers may be pinched between the car door 80 and the platform door 91. The car door 80 opens first, which can ensure that there is enough space for passengers to enter the car and reduce the risk of pinching. Therefore, the platform door 91 in this application should be opened after the car door 80 is opened.

[0053] It can be seen that the linkage control process of the platform door and the car door linkage control device includes: when the vehicle runs to the designated position and lands, the slide 20 contacts the trigger module on the guide rail 10, so that the trigger module generates a trigger signal after being triggered, and after the car door control module 50 receives the trigger signal, it issues a car door opening command to open the car door 80, and after the car door 80 is opened, the platform door control module 60 issues a platform door opening command to open the platform door 91.

[0054] With such a setting, when the traditional wireless system fails to complete the interlocking control between the platform door 91 and the vehicle door 80 after the vehicle arrives at the station, the platform door and vehicle door interlocking control device provided by the embodiment of the present application, after the vehicle arrives at the designated position and lands, realizes the interlocking control between the vehicle door 80 and the platform door 91 through the interlocking signal transmission control of the skid 20, the trigger module, the vehicle door control module 50, and the platform door control module 60, ensuring the safety and reliability of the opening of the vehicle door 80 and the platform door 91, and solving the technical problem that the traditional use of the wireless system cannot stably ensure the interlocking signal transmission control between the vehicle door 80 and the platform door 91.

[0055] Further, in order to ensure the opening of the interlocking control between the platform door 91 and the vehicle door 80, the platform door and vehicle door interlocking control device further includes a vehicle door detection module 70. The vehicle door detection module 70 is communicatively connected to the platform door control module 60 and is used to be installed on the platform 90 to detect whether the vehicle door 80 is in an open state.

[0056] In this way, when the vehicle door detection module 70 detects that the vehicle door 80 has been opened, the vehicle door detection module 70 sends a signal to the platform door control module 60, and then the platform door control module 60 controls the opening of the platform door 91.

[0057] In some embodiments, the platform door control module 60 includes a receiving unit 61, a judging unit 62, a processing unit 63, and a control unit 64.

[0058] Among them, the receiving unit 61 is communicatively connected to the vehicle door control module 50 and the vehicle door detection module 70. The receiving unit 61 is used to receive the vehicle door execution opening signal fed back by the vehicle door control module 50 and the vehicle door detection parameters fed back by the vehicle door detection module 70. The judging unit 62 is communicatively connected to the receiving unit 61, and the judging unit 62 is used to judge whether the vehicle door detection parameters reach a preset condition. The processing unit 63 is communicatively connected to the judging unit 62, and the processing unit 63 is used to process and generate a vehicle door confirmation opening signal when the vehicle door detection parameters reach the preset condition. The control unit 64 is communicatively connected to the processing unit 63, and the control unit 64 is used to control the opening of the platform door 91 after receiving the vehicle door execution opening signal and the vehicle door confirmation opening signal.

[0059] That is to say, the platform door control module 60 needs to control the opening of the platform door 91 after receiving the vehicle door execution opening signal fed back by the vehicle door control module 50 and the vehicle door confirmation opening signal generated by judging and processing through the vehicle door detection parameters fed back by the vehicle door detection module 70. Both conditions need to be met simultaneously to send the platform door 91 opening instruction to control the opening of the platform door 91.

[0060] In some embodiments, the door detection module 70 is a distance detection module. The distance detection module has a preset inclination angle with respect to the plane where the guide rail 10 is located. The distance detection module is configured to emit detection light towards the door 80 to detect whether the door 80 is in an open state.

[0061] It can be understood that the above-mentioned distance detection module is located on the platform 90 and has a certain inclination. The distance detection module can continuously monitor the distance l1 between the door 80 and the module. When the door 80 is opened, the door 80 is not within the detection range of the device, and the distance that the module can detect becomes the distance l2 from the device to a certain location inside the carriage. There is an obvious distance difference between l1 and l2. Therefore, when the door 80 is opened, the device can detect whether the door 80 is in an open state.

[0062] It should be noted that the above-mentioned door detection parameter reaching the preset condition can mean that the distance value detected by the distance detection module reaches the set threshold.

[0063] In some embodiments, the number of distance detection modules is at least two, and the array length formed by at least two distance detection modules is not less than the width of the door 80.

[0064] Specifically, the array formed by the distance detection modules is parallel to the driving direction of the vehicle, and the array length is not less than the width of the vehicle door 80; the number of distance detection modules is not specifically limited and is selected according to the width of the door 80 and the detection accuracy. It should be noted that the more the number of distance detection modules, the smaller the distance between adjacent distance detection modules, the more sensitive to the movement of the door 80, and the higher the detection accuracy; the distance between adjacent distance detection modules can be equal or unequal, and an equally spaced arrangement is preferred.

[0065] In some embodiments, the triggering module is a trigger circuit 41, and the trigger circuit 41 includes a trigger gasket 411, a circuit body 412, and a power supply unit 413.

[0066] Among them, the trigger gasket 411 is disposed on the surface of the guide rail 10, and the trigger gasket 411 is used to contact the skid 20; the circuit body 412 is built in the guide rail 10, the circuit body 412 is connected to the trigger gasket 411 and the door control module 50, and the circuit body 412 is used to generate a trigger signal; the power supply unit 413 is connected to the circuit body 412, and the power supply unit 413 is used to supply power to the circuit body 412.

[0067] In this way, when the vehicle reaches the designated position, the vehicle lands. After landing, the skid 20 of the vehicle contacts the trigger gasket 411. That is, a microcircuit (circuit body 412) is installed on the guide rail 10. By virtue of the conductive property of the skid 20 itself, a power supply loop is formed after the skid 20 contacts the trigger gasket 411, thereby achieving the purpose of controlling the opening of the vehicle door 80. When the vehicle is suspended, the vehicle is separated from the trigger gasket 411 and the vehicle door 80 closes.

[0068] In some embodiments, the trigger module is a trigger sensor 42. The trigger sensor 42 includes an induction contact, and the surface of the induction contact is flush with the surface of the guide rail 10. The trigger sensor 42 is used to generate a trigger signal when the induction contact contacts the skid 20.

[0069] In this way, when the vehicle reaches the designated position, the vehicle lands. After landing, the skid 20 of the vehicle contacts the induction contact of the trigger sensor 42, and the trigger sensor 42 generates a trigger signal, thereby achieving the purpose of controlling the opening of the vehicle door 80.

[0070] In some embodiments, two sets of trigger modules are provided. The skid 20 includes two sets of conductive contacts, and the distance between the two sets of conductive contacts is equal to the distance between the two sets of trigger modules, so that trigger signals are generated when the two sets of conductive contacts contact the two sets of trigger modules respectively.

[0071] It should be emphasized that to ensure that the two sets of trigger modules are triggered simultaneously, the distance between the two sets of trigger modules in the direction along the guide rail 10 should be equal to the distance between the two sets of conductive contacts on the skid 20. In this way, when the controlled device is a device with extremely strict position requirements such as the vehicle door 80, by further increasing the combined judgment logic, assuming that AB are two trigger sensors 42 or trigger circuits 41 on the same horizontal line, and CD are two trigger sensors 42 or trigger circuits 41 on the same horizontal line, and the distance between AB and CD is the size of one unit skid 20, the trigger conditions are as shown in Table 1 below:

[0072] Table 1

[0073] Situation Trigger situation Door opening situation Situation 1 Only AB is triggered The door does not open Situation 2 Only CD is triggered The door does not open Situation 3 ABCD are triggered simultaneously The door opens

[0074] Combined with the above, the complete linkage control process of the platform door and vehicle door linkage control device is as follows (taking the trigger module as the trigger circuit 41 as an example):

[0075] When the vehicle runs to a certain location (the parking accuracy of the high-speed maglev train is centimeter-level, and the high-speed maglev safety mechanism restricts the opening of the door 80 before it lands), and when it lands, the skid 20 contacts the trigger gasket 411 on the guide rail 10, the circuit body 412 is turned on, and at the same time, the door detection module 70 is in an available state. Before the door 80 is opened, the platform door 91 is not allowed to be opened. When and only when the platform door control module 60 receives the door execution opening signal fed back by the door control module 50, and the door detection module 70 detects a significant change in the distance of the door 80, that is, when the door 80 is confirmed to be opened, the platform door 91 is opened at this time. The control situation of the entire logic is as shown in Table 2 below:

[0076] Table 2

[0077] Vehicle disembarking situation Trigger situation of the trigger circuit or trigger sensor Distance value situation detected by the distance detection module Platform door opening situation The vehicle has not disembarked Not triggered <![CDATA[l1]]> Not opened The vehicle has disembarked Not triggered <![CDATA[l1]]> Not opened The vehicle has disembarked Triggered <![CDATA[l2]]> Opened

[0078] In addition, the platform door and door linkage control device further includes a prompt module, and the prompt module is used to be installed on the platform door 91. In this way, when the platform door 91 is opened or closed, the prompt module emits prompt sounds and / or lights to prompt the on-site staff.

[0079] In summary, in the present application, by means of the trigger sensor 42 or the trigger circuit 41, the stable transmission of the control signal is realized by using the characteristics of the vehicle's own landing and the conductivity of the skid 20, further ensuring the safety of passengers. The platform door and door linkage control device of the present application is applicable to the conventional high-speed maglev train in principle, and at the same time, it has a certain applicability to the superconducting high-speed maglev train.

[0081] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0082] The above has introduced in detail the platform door and door linkage control device and the track vehicle control system provided by the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the solution and its core idea of the present application.
