[0050] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] Combine the following Figure 1 A rail vehicle door control circuit of the present invention is described, comprising:

[0052] The first-end door control circuit and the second-end door control circuit of rail vehicles;

[0053] The front position of the rail vehicle is determined according to the driving direction of the rail vehicle. When the front position is at one end of the rail vehicle, the first-end door control circuit is triggered to control the door; when the front position is at the other end of the rail vehicle, the second-end door control circuit is triggered to control the door.

[0054] Figure 1 The left half is a single-end door control circuit, and the right half is a double-end door control circuit.

[0055] The one-terminal door control circuit comprises a first relay, a second relay, a signal plug box A01, a first knob S01 and a door controller;

[0056] The first relay is activated when the rail vehicle is in a fully automatic driving mode or a manual driving mode, and one end of the normally open auxiliary contact K01 of the first relay is connected to the positive electrode 101 of the power supply;

[0057] The first relay can be activated when the rail vehicle is in fully automatic driving mode or manual driving mode, indicating that the rail vehicle is occupied and door control is required.

[0058] The second relay is activated when the rail vehicle is in the fully automatic driving mode, and one end of the normally closed auxiliary contact K02 of the second relay is connected to the other end of the normally open auxiliary contact K01 of the first relay;

[0059] The normally closed auxiliary contact K02 of the second relay is connected to the first knob S01. In the fully automatic driving mode, the second relay is activated, the normally closed auxiliary contact K02 of the second relay is disconnected, and the driver's operation of the first knob S01 does not affect the door control.

[0060] In the manual driving mode, the second relay is not activated, the normally closed auxiliary contact K02 of the second relay is closed, and the driver's operation of the first knob S01 affects the door control.

[0061] The input end of the signal plug box A01 is connected to the other end of the normally open auxiliary contact K01 of the first relay, and the signal plug box A01 is used to send a door enabling instruction according to the output of the signal system of the rail vehicle;

[0062] The input end of the signal plug-in box A01 is connected to the signal system of the rail vehicle. When the rail vehicle is in full automatic driving mode, the signal system inputs the control signal of the rail vehicle to the signal plug-in box A01. The signal plug-in box A01 determines whether a door enabling instruction occurs according to the control signal.

[0063] The door enable command is a command to control the door to open or close.

[0064] The input end of the first knob S01 is connected to the other end of the normally closed auxiliary contact, and the first knob is used to send the door enabling instruction according to the driver's rotation operation;

[0065] The driver selects whether to control the vehicle door or which side of the vehicle door to control by rotating the first knob.

[0066] like Figure 1 When the driver rotates the first knob to the right door, the contact corresponding to the right door is connected, and the right door is controlled by the door controller of the right door; when the driver rotates the first knob to the left door, the contact corresponding to the left door is connected, and the left door is controlled by the door controller of the left door.

[0067] The door controller is used to receive the door enable command sent by the signal plug-in box or the first knob, and control the door of the rail vehicle to open or close according to the door enable command;

[0068] When the door controller is connected to the line of the signal plug-in box, it controls the door to open or close according to the door enable command sent by the signal plug-in box.

[0069] When the door controller is connected to the line of the first knob S01, the door controller controls the door to be opened or closed according to the door enabling instruction sent by the first knob S01.

[0070] The first relay, the second relay and the signal plug box are located on the chassis of the rail vehicle, and the first knob and the door controller are located in the carriage of the rail vehicle;

[0071] Signal box A01 Figure 1 Outlined with a dotted line.

[0072] The two-end door control circuit is the same as the one-end door control circuit.

[0073] This embodiment arranges the first relay, the second relay and the signal plug-in box in the door control circuit of the rail vehicle on the chassis of the rail vehicle, and only arranges the first knob and the door controller in the carriage of the rail vehicle, thereby realizing joint door control under the vehicle and on the vehicle, and the under-vehicle part is adapted to various carriages, reducing the cost of replacing the carriages, and is suitable for door control of rail vehicles with detachable chassis.

[0074] On the basis of the above embodiment, the one-terminal door control circuit in this embodiment further includes a third relay;

[0075] The input end of the third relay is connected to the output end of the signal plug-in box and to the output end of the first knob, the output end of the third relay is connected to the negative pole of the power supply, and the third relay is located on the chassis;

[0076] One end of the normally open auxiliary contact of the third relay is connected to the positive pole of the power supply, and the other end is connected to the door controller. The normally open auxiliary contact of the third relay is located in the vehicle compartment.

[0077] When the third relay is energized, the third relay is activated, triggering the normally open auxiliary contact of the third relay to close, thereby energizing the door controller connected to the normally open auxiliary contact of the third relay, activating the door controller to control the door of the rail vehicle.

[0078] This embodiment uses a third relay to achieve isolated control of the door controller, and is suitable for rail vehicles with detachable chassis. When the car and chassis are separated, the door enable signal cannot be transmitted to the door controller because the door controller is arranged in the car.

[0079] On the basis of the above embodiment, one output end of the signal plug-in box in this embodiment is used to send a door enabling instruction of a first side door of the rail vehicle according to the output of the signal system, and the other output end is used to send a door enabling instruction of a second side door of the rail vehicle according to the output of the signal system;

[0080] like Figure 1 As shown, the signal plug-in box A01 has two output terminals. For example, when the signal plug-in box determines to control the right door according to the output of the signal system, the right door enable command is output through one output terminal; when the signal plug-in box determines to control the left door according to the output of the signal system, the left door enable command is output through the other output terminal.

[0081] One output end of the first knob is used to send a door enabling instruction for the first side door according to the operation of the driver, and the other output end is used to output a door enabling instruction for the second side door according to the operation of the driver;

[0082] like Figure 1 As shown, the first knob S01 has two output terminals. For example, when the driver rotates the first knob to the right door contact, the right door enable command is output through one output terminal; when the driver rotates the first knob to the left door contact, the left door enable command is output through the other output terminal.

[0083] In addition, the first knob can also be decomposed into two buttons, namely, a right door enable button and a right door enable button, which can control the left door and the right door at the same time.

[0084] The one-terminal door control circuit has two third relays, an input end of one third relay is connected to an output end of the signal plug-in box, and is also connected to an output end of the first knob;

[0085] One end of the normally open auxiliary contact of the third relay is connected to the positive electrode of the power supply, and the other end is connected to the door controller of the first side door;

[0086] An input end of another third relay is connected to another output end of the signal plug-in box and is connected to another output end of the first knob;

[0087] One end of the normally open auxiliary contact of the other third relay is connected to the positive pole of the power supply, and the other end is connected to the door controller of the second side door.

[0088] The first-end door control circuit has two third relays K3 and K4, and the second-end door control circuit has two third relays K5 and K6.

[0089] The input end of K3 receives the right door enabling instruction output by the first one-bit signal plug-in box and the first one-bit knob, and the output end of K3 is connected to the negative electrode 100 of the power supply.

[0090] The input end of K4 receives the left door enabling instruction output by the first one-bit signal plug-in box and the first one-bit knob, and the output end of K4 is connected to the negative electrode 100 of the power supply.

[0091] like Figure 2 As shown, after K3 is activated, K03 is closed, and the door controllers D01 to D04 control the right door to open or close.

[0092] like Figure 3 As shown, after K4 is activated, K04 is closed, and the door controllers D05 to D08 control the opening or closing of the left door.

[0093] This embodiment realizes the first-end left door enable, the first-end right door enable, the second-end left door enable and the second-end right door enable, enriching the functions of the door control circuit.

[0094] On the basis of the above embodiment, in this embodiment, the input end of a third relay in the one-position door control circuit is also connected to an output end of a signal plug-in box in the two-position door control circuit, and is also connected to an output end of a first knob in the two-position door control circuit;

[0095] like Figure 1 As shown, the input end of K3 receives not only the right door enable signal output by S01 and A01 in the one-bit door control circuit, but also the left door enable signal output by S01 and A01 in the two-bit door control circuit. The one-bit right door enable is the two-bit left door enable, and the one-bit left door enable is the two-bit right door enable.

[0096] The input end of another third relay in the one-position door control circuit is also connected to another output end of the signal plug-in box in the two-position door control circuit, and is also connected to another output end of the first knob in the two-position door control circuit.

[0097] The input end of K4 not only receives the left door enable signal output by S01 and A01 in the one-end door control circuit, but also receives the right door enable signal output by S01 and A01 in the two-end door control circuit.

[0098] This embodiment realizes that when the left door at the first end is enabled, the right door at the second end is activated simultaneously, and when the right door at the first end is enabled, the left door at the second end is activated simultaneously. When the door enable relay at either end fails, the control of the door is not affected.

[0099] On the basis of the above embodiment, in this embodiment, the input end of the door controller is connected to the output end of the signal plug-in box, and the input end of the door controller is connected to the output end of the first knob.

[0100] In addition to using the third relay to transmit the door enable command to the door controller, this embodiment directly transmits the door enable command to the door controller through the train line, which simplifies the circuit structure and reduces costs.

[0101] Based on the above embodiment, the one-terminal door control circuit in this embodiment further includes a second knob;

[0102] The input end of the second knob is connected to the output end of the signal plug-in box, and the second knob is used to cut off the door enabling instruction sent by the signal plug-in box according to the rotation operation of the driver;

[0103] The output end of the second knob is connected to the input end of the third relay.

[0104] In the event of a signal system failure, in order to prevent the signal heartbeat from erroneously outputting instructions, according to the operating procedures, the second knob S02 is first rotated to the cut-off position. Even if the signal system erroneously triggers the door enable, the door enable relay will not be activated, ensuring the safe operation of the vehicle.

[0105] On the basis of the above embodiment, the signal plug-in box in this embodiment is used to control the closing of the contact switch in the signal plug-in box according to the output of the signal system;

[0106] like Figure 1 As shown, the signal plug-in box A01 includes two contact switches, namely, a right door enabling switch and a left door enabling switch.

[0107] The signal plug box A01 determines whether the right door or left door of the rail vehicle needs to be controlled according to the output of the signal system. When the right door needs to be controlled, the right door enable switch is closed; when the left door needs to be controlled, the left door enable switch is closed.

[0108] One end of the contact switch is connected to the other end of the normally open auxiliary contact of the first relay; the other end of the contact switch is connected to the input end of the third relay.

[0109] When the right door enable switch is closed, the third relays K3 and K6 connected to the right door enable switch are energized and activated, the normally open auxiliary contacts K03 and K06 of K3 and K6 are closed, and the door controllers D01, D02, D03 and D04 connected to K03 and K06 are activated, starting the door control. Figure 2 shown.

[0110] When the left door enable switch is closed, the third relays K4 and K5 connected to the left door enable switch are energized and activated, the normally open auxiliary contacts K04 and K05 of K4 and K5 are closed, and the door controllers D05, D06, D07 and D08 connected to K04 and K05 are activated, starting the door control. Figure 3 shown.

[0111] This embodiment realizes the first-end left door enable, the first-end right door enable, the second-end left door enable and the second-end right door enable, enriching the functions of the door control circuit.

[0112] The rail vehicle door control method provided by the present invention is described below. The rail vehicle door control method described below and the rail vehicle door control circuit described above can be referred to each other.

[0113] like Figure 4 As shown, the rail vehicle door control method provided in this embodiment is applied to the rail vehicle door control circuit described in any of the above embodiments, including:

[0114] Step 401, selecting a first-end door control circuit or a second-end door control circuit according to the head position of the rail vehicle;

[0115] The front position of the rail vehicle is determined according to the driving direction of the rail vehicle. When the front position is at one end of the rail vehicle, the first-end door control circuit is triggered to control the door; when the front position is at the other end of the rail vehicle, the second-end door control circuit is triggered to control the door.

[0116] Step 402, when the rail vehicle is in the fully automatic driving mode, activating the first relay and the second relay in the selected one-end door control circuit or the two-end door control circuit, the normally open auxiliary contact of the first relay is closed, and the normally closed auxiliary contact of the second relay is opened;

[0117] In the fully automatic mode, K01 in the first-end door control circuit or the second-end door control circuit is turned on and K02 is turned off according to the vehicle head position. Even if a person accidentally touches the first knob, relays K3, K4, K5 and K6 will not be activated, ensuring the operation scenario and driving safety of the vehicle controlled by the signal system in the fully automatic driving mode.

[0118] Step 403, sending a door enable instruction to a door controller through a signal plug-in box according to the output of the signal system of the rail vehicle, and the door controller controls the door of the rail vehicle to open or close according to the door enable instruction;

[0119] The signal plug box A01 judges according to the output of the signal system and sends a door enable command, such as a right door enable command. K3 and K6 are energized, K03 and K06 are closed, that is, the vehicle receives a first-end right door enable command and a second-end left door enable command, and transmits the first-end right door enable command and the second-end left door enable command to the corresponding door control system.

[0120] Step 404, when the rail vehicle is in manual driving mode, activating the first relay, and closing the normally open auxiliary contact of the first relay;

[0121] When the signal system is normal, the first relay is activated, K01 is turned on, and K02 is closed.

[0122] Step 405, sending the door enable instruction through the first knob according to the driver's rotation operation on the first knob, and the door controller controls the door of the rail vehicle to open or close according to the door enable instruction;

[0123] The first relay, the second relay and the signal plug-in box are located on the chassis of the rail vehicle, and the first knob and the door controller are located in the compartment of the rail vehicle.

[0124] The door enable command can be given by operating the first knob S01 or the signal plug box A01. When the door enable command is the right door enable command, K3 and K6 are activated, K03 and K06 are closed, that is, the vehicle obtains the first-end right door enable command and the second-end left door enable command, and transmits the first-end right door enable command and the second-end left door enable command to the corresponding door control system.

[0125] This embodiment arranges the first relay, the second relay and the signal plug-in box on the chassis of the rail vehicle, and only arranges the first knob and the door controller in the carriage of the rail vehicle, thereby realizing joint door control under the vehicle and on the vehicle, and the under-vehicle part is adapted to various carriages, reducing the cost of replacing the carriages, and is suitable for door control of rail vehicles with detachable chassis.

[0126] Based on the above embodiment, this embodiment also includes:

[0127] When the rail vehicle is in manual driving mode, if the signal system fails, the door enabling instruction sent by the signal plug-in box is cut off according to the driver's rotation operation on the second knob.

[0128] In the event of a signal system failure, in order to prevent the signal heartbeat from erroneously outputting instructions, according to the operating procedures, the second knob S02 is first rotated to the cut-off position. Even if the signal system erroneously triggers the door enable, the door enable relay will not be activated, ensuring the safe operation of the vehicle.

[0129] At this time, the first relay is activated, K01 is turned on, and K02 is closed. The door enable command is given by operating the first knob S01. When the door enable command is the right door enable command, K3 and K6 are activated, K03 and K06 are closed, that is, the vehicle obtains the first-end right door enable command and the second-end left door enable command, and transmits the first-end right door enable command and the second-end left door enable command to the corresponding door control system.

[0130] This embodiment provides a rail vehicle, comprising the rail vehicle door control circuit in any one of the above embodiments.
