[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The core of the utility model is to provide a vehicle-mounted control system for platform safety doors. The driver can control the opening and closing of the vehicle door and the platform safety door at the same time in the cab, which not only ensures the safety of passengers getting on and off the station, but also realizes the rapid opening and closing of the vehicle door and the doors on both sides of the platform safety door.

[0029] It should be noted that the on-board control system for platform safety doors provided in this application document is not only applicable to electronic guided rubber wheel systems, but also to rail transit systems such as trams, which also have difficulty in accurately controlling arrival times.

[0030] The utility model provides a vehicle-mounted control system for a station safety door, comprising:

[0031] The vehicle control box 1 is arranged in the cab of the rail vehicle 10 and is used to connect with the vehicle signal system signal to receive and transmit the vehicle door opening and closing signal sent by the vehicle signal system;

[0032] The vehicle-mounted transmitter 2 is arranged on the side of the rail vehicle 10, and is used to receive the vehicle door opening and closing signal transmitted by the vehicle-mounted control box 1, and send the corresponding platform door opening and closing signal to the outside;

[0033] The platform receiver 3 is disposed on the platform 20 , and is used to receive the platform door opening and closing signal, and transmit the platform door opening and closing signal to the door control unit of the platform safety door 201 .

[0034] It should be noted that the vehicle door opening and closing signal is the collective name for the vehicle door opening signal and the vehicle door closing signal, and the platform door opening and closing signal is the collective name for the platform door opening signal and the platform door closing signal.

[0035] The on-board control box 1 is used to receive the vehicle door opening and closing signal of the vehicle signal system and transmit the vehicle door opening and closing signal to the on-board transmitter 2; the on-board control box 1 is arranged in the driving cab of the rail vehicle 10, which is conducive to simplifying the line layout between the vehicle signal system and the on-board control box 1, and can shorten the signal transmission path between the two, shorten the response time, and improve the response speed of the on-board control box 1 to the vehicle door opening and closing signal.

[0036] In order to realize the round trip operation of the rail vehicle 10, a cab is provided at both ends of the rail vehicle 10, so a vehicle control box 1 is provided at both ends of the rail vehicle 10. Figure 1 and Figure 2 As shown; considering factors such as power supply and response time, the vehicle control box 1 is usually installed in the signal cabinet in the cab, which can shorten the length of the power line and the signal line 4, improve the response speed of the vehicle control box 1, and effectively protect the vehicle control box 1.

[0037] The on-board transmitter 2 is arranged on the side of the rail vehicle 10 so as to transmit the platform door opening and closing signal to the platform receiver 3 arranged on the platform 20; the side of the above-mentioned rail vehicle 10 includes both the side of the rail vehicle 10 body and the side of the cab. In order to shorten the length of the signal line 4, the on-board transmitter 2 is usually arranged on the side of the rail vehicle 10.

[0038] In order to prevent the vehicle-mounted transmitter 2 from affecting the driver's sight while driving, the vehicle-mounted transmitter 2 is usually installed on the upper part of the front windshield of the cab, that is, the upper left corner and / or upper right corner of the front windshield.

[0039] When the rail vehicle 10 opens and closes its doors on the same side along the route, the vehicle-mounted transmitter 2 may be arranged only on the side of the boarding and alighting stations in the direction of travel of the rail vehicle 10, such as Figure 1 As shown;

[0040] When the door opening and closing directions of the rail vehicle 10 along the line are inconsistent, in order to ensure that each platform 20 can receive the platform door opening and closing signal, the vehicle-mounted transmitter 2 needs to be installed on both sides of the rail vehicle 10, such as Figure 2 shown.

[0041] In order to ensure the connection stability of the vehicle-mounted transmitter 2 , the vehicle-mounted transmitter 2 is usually fixed to the side of the rail vehicle 10 through a transmitter mounting bracket to prevent the vehicle-mounted transmitter 2 from falling off and affecting the normal door opening and closing control of the rail vehicle 10 .

[0042] The platform receiver 3 is arranged at the platform 20, and is used to receive the platform door opening and closing signal sent by the vehicle-mounted transmitter 2, and transmit the above platform door opening and closing signal to the door control unit (Door Control Unit, abbreviated as DCU) of the platform safety door 201; considering the stability of signal transmission, the signal transmission between the platform receiver 3 and the vehicle-mounted transmitter 2 is currently mostly carried out in the form of wireless signals.

[0043] The platform receiver 3 may be arranged on the platform safety door 201 , or on the platform guardrail between two adjacent platform safety doors 201 . Of course, a receiver bracket specifically for mounting the platform receiver 3 may also be provided.

[0044] The model of the vehicle-mounted transmitter 2, especially the design transmission distance index of the vehicle-mounted transmitter 2, needs to comprehensively consider the height difference between the platform safety door 201 and the rail vehicle 10, the horizontal spacing between the platform safety door 201 and the rail vehicle 10, and the parking accuracy, that is, the distance difference between the platform safety door 201 and the rail vehicle 10 in the direction of travel of the rail vehicle when parking, so as to ensure the signal strength of the platform opening and closing door signal received by the platform receiver 3.

[0045] The design transmission distance of the vehicle-mounted transmitter 2 is usually set to 5m, which can ensure the signal strength at the platform receiver 3 on the one hand, and on the other hand, the power of the vehicle-mounted transmitter 2 is low, and the equipment cost and operation cost are both low.

[0046] After the rail vehicle 10 arrives at the station, the driver controls the vehicle signal system to send a vehicle door opening signal. On the one hand, the vehicle door control unit receives the door opening signal and opens the vehicle door; on the other hand, the vehicle control box 1 transmits the door opening signal to the vehicle transmitter 2, and the vehicle transmitter 2 sends a platform door opening signal to the platform receiver 3 at the platform 20. The platform receiver 3 receives and then transmits the platform door opening signal to the door control unit of the platform safety door 201 to open the platform safety door 201;

[0047] After the vehicle stop time is over, the driver controls the vehicle signal system to send a vehicle door closing signal. On the one hand, the vehicle door control unit closes the vehicle door; on the other hand, the vehicle control box 1 transmits the vehicle door closing signal to the vehicle transmitter 2, and the vehicle transmitter 2 sends a platform door closing signal. The platform receiver 3 receives and transmits the platform door closing signal to the door control unit of the platform safety door 201, and closes the platform safety door 201.

[0048] In this embodiment, the driver can control the opening and closing of the vehicle door and the platform safety door 201 at the same time in the cab, which not only ensures the safety of passengers getting on and off the station, but also enables the timely and rapid opening and closing of the vehicle door and the platform safety door 201 on both sides, solving the problem of rapid and safe opening of the platform safety door 201 of the rail vehicle 10 whose accurate arrival time is difficult to control.

[0049] The signal transmission path of the platform door switch signal that controls the platform safety door 201 switch is usually longer than the signal transmission path of the vehicle door switch signal that controls the vehicle door switch of the rail vehicle 10. Therefore, the response speed of the vehicle door switch is usually faster than the response speed of the platform safety door 201 switch.

[0050] On the basis of the above embodiment, a delay device can also be provided. The delay device is arranged between the vehicle signal system and the vehicle door control unit. The delay device is used to receive the vehicle door opening and closing signal sent by the vehicle signal system and transmit the vehicle door opening and closing signal to the vehicle door control system after a preset time.

[0051] Assume that after the driver inputs the vehicle door opening and closing signal, the response time required by the vehicle door control unit is t1, the response time required by the door control unit of the platform safety door 201 is t2 (t2≥t1), and the preset time of the delay device is t;

[0052] When the preset time of the delay device is greater than the response time difference between the door control unit of the platform safety door 201 and the vehicle door control unit, that is, t+t1>t2, the platform safety door 201 can be controlled to be opened and closed earlier than the vehicle door;

[0053] When the preset time of the delay device is equal to the response time difference between the door control unit of the platform safety door 201 and the vehicle door control unit, that is, t+t1=t2, the platform safety door 201 and the vehicle door can be controlled to open and close at the same time;

[0054] When the preset time of the delay device is less than the response time difference between the door control unit of the platform safety door 201 and the vehicle door control unit, that is, t+t1<t2, the opening and closing of the platform safety door 201 can be controlled later than the opening and closing of the vehicle door.

[0055] In this embodiment, a delay device is arranged between the vehicle signal system and the vehicle door control unit. The delay device can adjust the opening and closing sequence of the vehicle door and the platform safety door 201, so that when opening, the vehicle door is earlier than the platform safety door 201, which is convenient for passengers to "get off first and get on later", and when closing, the platform safety door 201 is above the vehicle door to ensure the safety of passengers.

[0056] Based on the above embodiment, the structure of the vehicle control box 1 is defined, please refer to Figure 1The vehicle control box 1 includes a controller box body 101, and a vehicle controller is arranged in the controller box body 101. The model and type of the vehicle controller can be determined by referring to the vehicle controllers of rail transportation vehicles such as high-speed rail and subway to ensure the reliability and stability of the vehicle controller;

[0057] The controller box 101 is provided with a power interface 103 for connecting to a power line, a communication port 104 for connecting to a vehicle signal system, and a signal interface 105 for connecting to a vehicle transmitter 2, wherein the communication port 104 may include a CAN communication interface and / or a network communication interface.

[0058] In order to ensure the electrical safety of each component and each interface in the controller box body 101, a grounding stud 102 is provided on one side of the controller box body 101, and the grounding stud 102 is connected to the grounding wire;

[0059] The specific types and models of the grounding stud 102 , the power interface 103 , the communication port 104 , and the signal interface 105 are determined based on actual production needs and will not be described in detail here.

[0060] Preferably, the communication port 104 is connected to the vehicle signal system via a signal line 4, and the signal interface 105 is connected to the vehicle-mounted transmitter 2 via a signal line 4, so as to increase the signal transmission speed, reduce the response time of the door control unit of the platform safety door 201, and ensure the stability and reliability of signal transmission.

[0061] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
