Technical Field

[0001] This application relates to the technical field of rail transit, and particularly relates to a network control method for an opening and closing mechanism and a coupler, and a rail vehicle. Background Art

[0002] In the design of high-speed multiple units, the coupling operation refers to connecting two multiple units together to form an integral operation unit; the decoupling operation is to separate the coupled multiple units and restore them to independent operation units.

[0003] In the existing coupling and decoupling control technologies of multiple units, there are certain limitations in the interlocking control of the front-end opening and closing mechanism and the coupler. For example, the existing coupling and decoupling operations usually require manual intervention, the operation process is complex and time-consuming, and it is easy to cause operation errors due to human factors. In addition, the existing control methods lack an effective feedback mechanism during the coupling and decoupling processes, and cannot monitor and adjust the action states of the opening and closing mechanism and the coupler in real time, thus affecting the reliability and safety of coupling and decoupling. Summary of the Invention

[0004] The purpose of this application is to provide a network control method for an opening and closing mechanism and a coupler, which effectively improves the reliability and safety of coupling and decoupling operations through the flexible switching between manual and automatic control processes, reduces operation errors caused by human factors, and at the same time enhances the automation level and operation efficiency of the system.

[0055] This application also provides a rail vehicle that adopts the above network control method for the opening / closing mechanism and the coupler.

[0056] Compared with the above background technology, the network control method for the opening / closing mechanism and the coupler provided by this application mainly includes: judging the emergency coupling enable signal. If the emergency coupling enable signal is valid, it enters the manual control process; in the manual control process, judging the hardwired coupling signal. If the hardwired coupling signal is valid, it starts the manual coupling; if the hardwired coupling signal is invalid, judging the hardwired decoupling signal. If the hardwired decoupling signal is valid, it starts the manual decoupling; if the emergency coupling enable signal is invalid, judging the start coupling signal. If the start coupling signal is valid, it enters the automatic control process; in the automatic control process, judging the human-machine interface coupling signal. If the human-machine interface coupling signal is valid, it starts the automatic coupling; if the human-machine interface coupling signal is invalid, judging the human-machine interface decoupling signal. If the human-machine interface decoupling signal is valid, it starts the automatic decoupling.

[0057] In the existing coupling and decoupling control technologies of EMUs, there are problems such as complex operation, time-consuming, and prone to errors caused by human factors. At the same time, there is a lack of an effective feedback mechanism, which affects the reliability and safety of coupling and decoupling. In response to these problems, this application provides a network control method for the opening / closing mechanism and the coupler. By flexibly switching between the manual and automatic control processes, it effectively improves the reliability and safety of the coupling and decoupling operations, reduces operation errors caused by human factors, and at the same time enhances the automation level and operation efficiency of the system.

[0058] Specifically, the network control method of the present application first determines the emergency coupling enable signal. When the emergency coupling enable signal is valid, the system enters the manual control process. In this mode, the operator can directly trigger the manual coupling operation through the hardwired coupling signal, or trigger the manual decoupling operation through the hardwired decoupling signal. This manual control process provides the operator with direct control power. Especially in emergency situations or when the automatic control fails, it can quickly take measures to ensure the reliability of the coupling and decoupling operations. Through the direct control of the hardwired signal, the risks caused by network communication failures or human errors are reduced, and the safety of the operation is improved.

[0059] On the other hand, when the emergency coupling enable signal is invalid, the system will determine the start coupling signal. If the start coupling signal is valid, the system enters the automatic control process. In the automatic control process, the system will further determine the human-machine interface coupling signal. If this signal is valid, the system will automatically execute the coupling operation; if the human-machine interface coupling signal is invalid, the system will determine the human-machine interface decoupling signal. If this signal is valid, the automatic decoupling operation will be executed. This automatic control process uses the human-machine interface to receive the operator's instructions, realizing the automation of the coupling and decoupling operations, improving the operation efficiency and convenience. Through the automatic control process, the system can quickly respond to the operator's instructions, reducing the operation time and also reducing the operation errors caused by human factors.

[0060] Combined with the above structure and process description, it can be seen that the network control method of the opening and closing mechanism and the coupler has at least the following beneficial effects: The network control method of the opening and closing mechanism and the coupler, through the flexible switching between the manual and automatic control processes, effectively improves the reliability and safety of the coupling and decoupling operations, reduces the operation errors caused by human factors, and at the same time enhances the automation level and operation efficiency of the system.

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 of the present application without creative efforts shall fall within the protection scope of the present application.

[0072] In order to enable those skilled in the art of the present 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.

[0073] Please refer to Figure 1 and Figure 2 , Figure 1 Schematic diagram of the network control method for the opening and closing mechanism and coupler provided by the embodiment of the present application, Figure 2 Flowchart of the network control method for the opening and closing mechanism and coupler provided by the embodiment of the present application. Figure 2 The HMI in is a human-machine interface.

[0074] In the first specific implementation manner, the network control method for the opening and closing mechanism and the coupler provided by the implementation solution of the present application mainly includes: S1. Judge the emergency coupling enable signal. If the emergency coupling enable signal is valid, enter the manual control process; if the emergency coupling enable signal is invalid, judge the start coupling signal. If the start coupling signal is valid, enter the automatic control process. S2. In the manual control process, judge the hardwired coupling signal. If the hardwired coupling signal is valid, start the manual coupling; if the hardwired coupling signal is invalid, judge the hardwired decoupling signal. If the hardwired decoupling signal is valid, start the manual decoupling. S3. In the automatic control process, judge the human-machine interface coupling signal. If the human-machine interface coupling signal is valid, start the automatic coupling; if the human-machine interface coupling signal is invalid, judge the human-machine interface decoupling signal. If the human-machine interface decoupling signal is valid, start the automatic decoupling.

[0075] In the existing coupling and decoupling control technologies of EMUs, there are problems such as complex operation, time-consuming, and easy to cause mistakes due to human factors. At the same time, there is a lack of an effective feedback mechanism, which affects the reliability and safety of coupling and decoupling. To address these problems, the present application provides a network control method for the opening and closing mechanism and the coupler. By flexibly switching between the manual and automatic control processes, the reliability and safety of the coupling and decoupling operations are effectively improved, the operation mistakes caused by human factors are reduced, and at the same time, the automation degree and operation efficiency of the system are enhanced.

[0076] Specifically, the network control method of the present application first judges the emergency coupling enable signal. When the emergency coupling enable signal is valid, the system enters the manual control process. In this mode, the operator can directly trigger the manual coupling operation through the hardwired coupling signal, or trigger the manual decoupling operation through the hardwired decoupling signal. This manual control process provides the operator with direct control power. Especially in emergency situations or when the automatic control fails, it can quickly take measures to ensure the reliability of the coupling and decoupling operations. Through the direct control of the hardwired signal, the risks caused by network communication failures or human misoperations are reduced, and the operation safety is improved.

[0077] On the other hand, when the emergency coupling enable signal is invalid, the system will judge the start coupling signal. If the start coupling signal is valid, the system will enter the automatic control process. In the automatic control process, the system will further judge the human-machine interface coupling signal. If this signal is valid, the system will automatically execute the coupling operation; if the human-machine interface coupling signal is invalid, the system will judge the human-machine interface decoupling signal. If this signal is valid, it will automatically execute the decoupling operation. This automatic control process uses the human-machine interface to receive the operator's instructions, realizing the automation of the coupling and decoupling operations, improving the operation efficiency and convenience. Through the automatic control process, the system can quickly respond to the operator's instructions, reduce the operation time, and at the same time reduce the operation mistakes caused by human factors.

[0078] Combined with the above structure and process description, it can be seen that the network control method for the opening and closing mechanism and the coupler has at least the following beneficial effects: The network control method for the opening and closing mechanism and the coupler effectively improves the reliability and safety of the coupling and decoupling operations through the flexible switching between manual and automatic control processes, reduces operation errors caused by human factors, and at the same time enhances the automation level and operation efficiency of the system.

[0079] In some cases, the emergency coupling enable signal can adopt a non-self-resetting knob. By operating the knob, an emergency coupling enable signal is generated for manually triggering the coupling and decoupling functions of the input and output control unit in case of network communication failure.

[0080] It should be noted that the manual coupling priority is higher than the automatic coupling, and the manual decoupling priority is higher than the automatic decoupling.

[0081] In some cases, both the hardwired coupling signal and the hardwired decoupling signal can adopt self-resetting knobs. By operating the corresponding knobs, the corresponding signals are generated.

[0082] In some cases, a human-machine interface is formed on the display. When the driver's key is inserted, by clicking the start coupling button in the human-machine interface, a human-machine interface coupling signal is generated; by clicking the start decoupling button, a human-machine interface decoupling signal is generated.

[0083] In a specific implementation, for the coupling control process, automatic coupling: Click the start coupling button on the display, and the central control unit forwards the instruction to the input and output control unit, and the input and output control unit automatically completes the coupling control process.

[0084] In some embodiments, after starting the manual coupling, it further includes:

[0085] Judge the coupling signal. If the coupling signal is valid, perform coupling control; or,

[0086] Judge the coupling signal successively. If the coupling signal is triggered once, perform one-step control.

[0087] In this embodiment, manual coupling: When the input and output control unit monitors the emergency coupling enable signal (high level valid), it enters the manual coupling control process; when it monitors the coupling signal (pulse signal, high level valid), it performs coupling control. Currently, there are two schemes: one is that after the input and output control unit monitors the coupling signal (pulse signal, high level valid), it automatically completes the control of the subsequent coupling steps; the other is that each time the coupling signal (pulse signal, high level valid) is monitored and triggered, one-step control is performed.

[0088] In a specific embodiment, for the decoupling control process, automatic decoupling: When the operation start decoupling button is clicked on the coupler end display and the vehicle speed is lower than 5 km / h, the decoupling control starts. The central control unit forwards the instruction to the input / output control unit, and the input / output control unit automatically completes the decoupling control process.

[0089] In some embodiments, after starting the manual decoupling, it further includes:

[0090] Judging the decoupling signal. If the decoupling signal is valid, perform the decoupling control; or,

[0091] Successively judge the decoupling signal. If the decoupling signal is triggered once, perform one-step control.

[0092] In this embodiment, for manual decoupling: When the input / output control unit monitors the emergency coupler enable signal (high level valid), it enters the manual coupler control process; when it monitors the decoupling signal (pulse signal, high level valid), it performs the decoupling control. Currently, there are two schemes: One is that after the input / output control unit monitors the decoupling signal (pulse signal, high level valid), it automatically completes the control of the subsequent decoupling steps; the other is that for each time the decoupling signal (pulse signal, high level valid) is monitored and triggered, one-step control is performed.

[0093] In a specific embodiment, the process of automatic coupler connection includes head cover unlocking, head cover opening, head cover locking, coupler unlocking, coupler extending, coupler locking, and coupler connection;

[0094] The process of automatic decoupling includes coupler decoupling, coupler unlocking, coupler retracting, coupler locking, head cover unlocking, head cover closing, and head cover locking.

[0095] Please refer to Figure 3 and Figure 4 , Figure 3 which is the schematic diagram of the opening and closing mechanism provided by the embodiment of the present application Figure 1 , Figure 4 which is the schematic diagram of the opening and closing mechanism provided by the embodiment of the present application Figure 2 .

[0096] For the opening and closing mechanism, the opening and closing mechanism includes an upper head cover device 1 and a lower head cover device 2. The upper head cover device 1 and the lower head cover device 2 are distributed up and down. Through the movement of the upper head cover device 1 and the lower head cover device 2, the opening and closing of the opening and closing mechanism are realized.

[0097] For the upper hood device 1, the upper hood device 1 includes an upper hood and two symmetrically arranged upper hood driving mechanisms on the left and right, defined as the first side and the second side. Each upper hood driving mechanism on either side is provided with an upper hood moving component 11 and an upper hood flipping component 12. The upper hood moving component 11 is provided with a motor and a lead screw. The lead screw is inclined upward. By driving the lead screw with the motor, when the upper hood flipping component 12 is driven by the lead screw to retract, it moves obliquely upward. The upper hood flipping component 12 is provided with a motor and a linkage mechanism. By driving the linkage mechanism with the motor, the upper hood is driven to retract horizontally and flip, specifically to rotate upward. Therefore, the upper hood realizes horizontal retraction and flipping through the motors of the two upper hood flipping components 12 on the first side and the second side, and realizes oblique retraction through the motors of the two upper hood moving components 11 on the first side and the second side.

[0098] For the lower hood device 2, the lower hood device 2 includes a lower hood and two symmetrically arranged lower hood driving mechanisms on the left and right, defined as the first side and the second side. Each lower hood driving mechanism on either side is provided with a lower hood moving component 21 and a lower hood flipping component 22. The lower hood moving component 21 is provided with a motor and a lead screw. The lead screw is inclined downward. By driving the lead screw with the motor, when the lower hood flipping component 22 is driven by the lead screw to retract, it moves obliquely downward. The lower hood flipping component 22 is provided with a motor and a linkage mechanism. By driving the linkage mechanism with the motor, the lower hood is driven to flip, specifically to rotate downward. Therefore, the lower hood realizes flipping through the motors of the two lower hood flipping components 22 on the first side and the second side, and realizes oblique retraction through the motors of the two lower hood moving components 21 on the first side and the second side.

[0099] In some cases, the motor of the upper hood flipping component 12 on the first side is the first motor 121, and the motor of the upper hood flipping component 12 on the second side is the fifth motor 122. The motor of the upper hood moving component 11 on the first side is the third motor 111, and the motor of the upper hood moving component 11 on the second side is the seventh motor 112. The motor of the lower hood flipping component 22 on the first side is the second motor 221, and the motor of the lower hood flipping component 22 on the second side is the sixth motor 222. The motor of the lower hood moving component 21 on the first side is the fourth motor 211, and the motor of the lower hood moving component 21 on the second side is the eighth motor 212.

[0100] Among them, the first motor 121 and the fifth motor 122, as the upper hood horizontal retraction and flipping motors, can be controlled by a single master driver or can be respectively equipped with drivers; the third motor 111 and the seventh motor 112, as the upper hood oblique retraction motors, can be controlled by a single master driver or can be respectively equipped with drivers; the second motor 221 and the sixth motor 222, as the lower hood flipping motors, can be controlled by a single master driver or can be respectively equipped with drivers; the fourth motor 211 and the eighth motor 212, as the lower hood oblique retraction motors, can be controlled by a single master driver or can be respectively equipped with drivers.

[0101] In some embodiments, automatic coupling includes upper hood opening control, lower hood opening control, and coupler control. The central control unit forwards instructions to the input / output control unit, and the input / output control unit automatically completes the coupling control process.

[0102] In this embodiment, the opening of the upper hood means the retraction, flipping, and diagonal retraction of the upper hood, and the opening of the lower hood means the flipping and diagonal retraction of the lower hood.

[0103] The conditions for starting coupling are as follows.

[0104] When the input / output control unit determines that the communication with the first to eighth motors (or the main driver) is abnormal, it prompts "hood motor communication failure" and stops executing downward.

[0105] After the input / output control unit receives the signals of "motor unavailable" or "driver unavailable" sent by the drivers of the first to eighth motors, it prompts "motor unavailable" or "driver unavailable".

[0106] In addition, the following steps are for the self-resetting process when the hoods are not in the initial position at the start of coupling (considering that there may be interference during the movement of the upper and lower hoods. If there is interference in the initial position).

[0107] If the input / output control unit monitors that there is no feedback on the signal of the lower hood's diagonal retraction and closing in place (high level valid), the input / output control unit outputs the brake unlocking signals for the fourth and eighth motors (1 = unlocking, 0 = braking) and sends the motor forward instructions to the fourth and eighth motor drivers (or the main driver) respectively through CAN communication. After waiting for 10 s, if it monitors the feedback on the signal of the lower hood's diagonal retraction and closing in place (high level valid), it stops outputting the brake unlocking signals for the fourth and eighth motors and proceeds to the next step; otherwise, it stops executing downward and cancels the motor forward instructions.

[0108] If the input / output control unit monitors that there is no feedback on the signal of the lower hood's flipping and closing in place (high level valid), the input / output control unit outputs the brake unlocking signals for the second and sixth motors (1 = unlocking, 0 = braking) and sends the motor forward instructions to the second and sixth motor drivers (or the main driver) respectively through CAN communication. After waiting for 6 s, if it monitors the feedback on the signal of the lower hood's flipping and closing in place (high level valid), it stops outputting the brake unlocking signals for the second and sixth motors and proceeds to the next step; otherwise, it stops executing downward and cancels the motor forward instructions.

[0109] When the input / output control unit monitors that there is no feedback on the signal indicating that the upper hood is retracted obliquely and closed in place (high level is valid), the input / output control unit outputs the third motor brake unlock signal and the seventh motor brake unlock signal (1 = unlock, 0 = brake), and sends the motor forward command to the third motor driver and the seventh motor driver (or the master driver) respectively through CAN communication. After waiting for 10 s, if the signal indicating that the upper hood is retracted obliquely and closed in place (high level is valid) is detected with feedback, continue; otherwise, stop executing downward and cancel the motor forward command.

[0110] When the input / output control unit monitors that there is no feedback on the signal indicating that the upper hood is retracted horizontally, flipped and closed in place (high level is valid), the input / output control unit outputs the first motor brake unlock signal and the fifth motor brake unlock signal (1 = unlock, 0 = brake), and sends the motor forward command to the first motor driver and the fifth motor driver (or the master driver) respectively through CAN communication. After waiting for 8 s, if the signal indicating that the upper hood is retracted horizontally, flipped and closed in place (high level is valid) is detected with feedback, stop outputting the first motor brake unlock signal and the fifth motor brake unlock signal, and proceed to the next step; otherwise, stop executing downward, cancel the motor forward command.

[0111] In some embodiments, the control for opening the automatically couplable upper hood includes:

[0112] The input / output control unit outputs the brake unlock signal for the upper hood retraction and flipping motor, sends the motor backward command to the driver of the upper hood retraction and flipping motor, and after waiting for a preset time, if the signal indicating that the upper hood retraction and flipping is opened in place is monitored with feedback, stop outputting the brake unlock signal for the upper hood retraction and flipping motor and proceed to the next step;

[0113] The input / output control unit outputs the brake unlock signal for the upper hood oblique retraction motor, sends the motor backward command to the driver of the upper hood oblique retraction motor, and after waiting for a preset time, if the signal indicating that the upper hood oblique retraction is opened in place is monitored with feedback, stop outputting the brake unlock signal for the upper hood oblique retraction motor and proceed to the next step.

[0114] Specifically, the input / output control unit outputs the first motor brake unlock signal and the fifth motor brake unlock signal (1 = unlock, 0 = brake), and sends the motor backward command to the first motor driver and the fifth motor driver (or the master driver) respectively through CAN communication. After waiting for 8 s, if the signal indicating that the upper hood retraction and flipping is opened in place (high level is valid) is monitored with feedback, the status display on the monitor changes to green for prompting, stop outputting the first motor brake unlock signal and the fifth motor brake unlock signal, and proceed to the next step; otherwise, stop executing downward, at the same time the status display on the monitor changes to red for prompting (reporting a fault), and stop sending the motor backward command;

[0115] If the forced next-step signal is received on the display, continue to execute the action and judgment of the upper hood retracting and flipping open in place signal;

[0116] If the end-of-coupling signal is received on the display, exit the coupling process, return to the start-of-coupling signal step, clear all output commands, and maintain the current state.

[0117] The input / output control unit outputs the third motor brake unlock signal and the seventh motor brake unlock signal (1 = unlock, 0 = brake), and sends the motor backward command to the third motor driver and the seventh motor driver (or the total driver) respectively through CAN communication. After waiting for 10 s, if the upper hood retracting and opening in place signal (high level valid) feedback is detected, the status on the display changes to a green prompt, stop outputting the third motor brake unlock signal and the seventh motor brake unlock signal, and proceed to the next step; otherwise, stop executing downward, at the same time, the status on the display changes to a red prompt (reporting a fault), and stop sending the motor backward command;

[0118] If the forced next-step signal is received on the display, continue to execute the action and judgment of the upper hood retracting and opening in place signal;

[0119] If the end-of-coupling signal is received on the display, exit the coupling process, return to the start-of-coupling signal step, clear all output commands, and maintain the current state.

[0120] In some embodiments, the control of opening the lower hood during automatic coupling includes:

[0121] The input / output control unit outputs the lower hood flipping motor brake unlock signal, sends the motor backward command to the driver of the lower hood flipping motor, and performs a preset time count. If the lower hood flipping and opening in place signal feedback is received within the set time, stop outputting the lower hood flipping motor brake unlock signal and proceed to the next step;

[0122] The input / output control unit outputs the lower hood retracting motor brake unlock signal, sends the motor backward command to the driver of the lower hood retracting motor, and performs a preset time count. If the lower hood retracting and opening in place signal feedback is received within the set time, stop outputting the lower hood retracting motor brake unlock signal and proceed to the next step.

[0123] Specifically, the input / output control unit outputs the second motor brake unlock signal and the sixth motor brake unlock signal (1 = unlock, 0 = brake), and sends the motor backward commands to the second motor driver and the sixth motor driver respectively through CAN communication, and starts an 8-second timer. If the feedback of the lower cowl flip-up in-place signal (high level valid) is received within the specified time, the status displayed on the monitor changes to a green prompt, the output of the second motor brake unlock signal and the sixth motor brake unlock signal stops, and the next step is carried out; if the feedback of the lower cowl flip-up in-place signal is not received within the specified time, the downward execution stops, at the same time the status displayed on the monitor changes to a red prompt (reporting a fault), and the motor backward commands stop being sent.

[0124] If the forced next step signal on the monitor is received, the action and judgment of the lower cowl flip-up in-place signal are executed again;

[0125] If the end coupling signal on the monitor is received, the coupling process exits, returns to the start coupling signal step, clears all output commands, and maintains the current state.

[0126] The input / output control unit outputs the fourth motor brake unlock signal and the eighth motor brake unlock signal (1 = unlock, 0 = brake), and sends the motor backward commands to the fourth motor driver and the eighth motor driver respectively through CAN communication, and starts an 8-second timer. If the feedback of the lower cowl diagonal retraction in-place signal (high level valid) is received within the specified time, the status displayed on the monitor changes to a green prompt, the output of the fourth motor brake unlock signal and the eighth motor brake unlock signal stops, and the next step is carried out; if the feedback of the lower cowl diagonal retraction in-place signal is not received within the specified time, the downward execution stops, at the same time the status displayed on the monitor changes to a red prompt (reporting a fault), and the motor backward commands stop being sent.

[0127] If the forced next step signal on the monitor is received, the action and judgment of the upper cowl diagonal retraction in-place signal are executed again;

[0128] If the end coupling signal on the monitor is received, the coupling process exits, returns to the start coupling signal step, clears all output commands, and maintains the current state.

[0129] In some embodiments, the coupler control for automatic coupling includes:

[0130] The input / output control unit monitors the feedback of the coupler retraction in-place signal. If the feedback is in place, it outputs the coupler retraction command and starts a preset time timer; if the feedback is not in place, it outputs the coupler retraction command and starts a preset time timer. If the feedback of the coupler retraction in-place signal is received within the set time, the next step is carried out;

[0131] The input / output control unit outputs a locking release instruction and starts timing for a preset time. If a signal feedback indicating that the coupler unlocking is in place is received within the set time, proceed to the next step; if no such signal feedback is received within the set time, stop executing further and stop the input / output control unit from outputting the locking release instruction.

[0132] After the input / output control unit detects a signal indicating that the coupler unlocking is in place, continuously output the locking release instruction by the input / output control unit.

[0133] The input / output control unit outputs a coupler extension instruction and starts timing for a preset time. If a signal feedback indicating that the coupler extension is in place is received within the set time, proceed to the next step; if no such signal feedback is received within the set time, stop executing further and stop outputting the coupler extension instruction.

[0134] The input / output control unit stops outputting the locking release instruction and starts timing for a preset time. If a signal feedback indicating that the coupler locking is in place is received within the set time, proceed to the next step; if no such signal feedback is received within the set time, stop executing further and output the locking release instruction through the input / output control unit.

[0135] Start timing for a preset time. If the input / output control unit detects a signal indicating that the mechanical coupler decoupling is in place, enter the coupled ready signal state.

[0136] After entering the coupled ready signal, wait for the train to be coupled.

[0137] Judge the coupling / decoupling mode signal. If the coupling / decoupling mode signal is valid, control the train to move forward, impact the coupler, and detect the signal feedback indicating that the mechanical coupler coupling is in place. If the feedback is detected, proceed to the next step.

[0138] After a preset time delay, output an air pipe opening instruction through the input / output control unit and start timing for a preset time. If a signal feedback indicating that the air pipe is opened is received within the set time, proceed to the next step; if no such signal feedback is received within the set time, stop executing further and stop the input / output control unit from outputting the air pipe opening instruction.

[0139] After a preset time delay, stop the input / output control unit from outputting the air pipe opening instruction.

[0140] The input / output control unit outputs an electrical connector connection instruction and starts timing for a preset time. If a signal feedback indicating that the electrical coupler extension is in place is received within the set time, proceed to the next step; if no such signal feedback is received within the set time, stop the input / output control unit from outputting the electrical connector connection instruction.

[0141] After a preset time delay, stop outputting the electrical connector connection instruction.

[0142] Perform preset time counting. If the signal feedback of coupling completion is received within the set time, the coupling completion signal is displayed after a preset time delay. If the signal feedback of coupling completion is not received within the set time, the electrical connector connection instruction is output through the input / output control unit.

[0143] Specifically, the input / output control unit monitors the feedback of the signal that the coupler is retracted into place (high level is valid): If the feedback indicates in place, the coupler retraction instruction is output (high level is open, low level is locked), and a 2s time count is performed (to eliminate the internal stress between the hook and the lock);

[0144] If the feedback is not in place, the coupler retraction instruction is output (high level is open, low level is locked), and a 10s time count is performed. If the signal feedback that the coupler is retracted into place (high level is valid) is received within the specified time, the next step is carried out; if the signal feedback that the coupler is retracted into place is not received within the specified time, the execution stops downward. At the same time, the status displayed on the monitor changes to a red prompt, and the human-machine interface reports the fault of "the coupler retraction is not in place", and the coupler retraction instruction (high level is valid) output stops.

[0145] The input / output control unit outputs the lock release instruction (high level is open, low level is locked).

[0146] After the input / output control unit outputs the lock release instruction, a 10s time count is performed. If the signal feedback that the coupler is unlocked in place (high level is valid) is received within the specified time, the status displayed on the monitor changes to a green prompt, and the next step is carried out; if the signal feedback that the coupler is unlocked in place is not received within the specified time, the execution stops downward. At the same time, the status displayed on the monitor changes to a red prompt, and the human-machine interface reports the faults of "the coupler is not unlocked" or "the coupler is not unlocked in place", and the input / output control unit stops outputting the lock release instruction.

[0147] If the forced next step signal on the monitor is received, the lock release instruction is output again through the input / output control unit, and the judgment of the coupler unlocking in place signal continues to be executed.

[0148] If the end of coupling signal on the monitor is received, the coupling process is exited, and the steps return to the start of coupling signal, clearing all current output instructions and maintaining the current state (at this time, since the coupler is at a low level and locked, it will automatically return to the locked state after the instruction is revoked).

[0149] After the input / output control unit detects the coupler unlocking in place signal (high level is valid), the status displayed on the monitor changes to a green prompt, and the input / output control unit continues to output the lock release instruction (high level is open, low level is locked).

[0150] The input / output control unit outputs the coupler extension instruction (level, high level is valid).

[0151] After the input / output control unit outputs the coupler extension command, a 60-second timer is started. If the coupler extension in-place signal (high level valid) feedback is received within the specified time, the status displayed on the monitor changes to a green prompt, and the next step is carried out; if the coupler extension in-place signal feedback is not received within the specified time, the execution stops, and at the same time, the status displayed on the monitor changes to a red prompt. At the same time, the human-machine interface reports "the coupler has not extended (the retracted-in-place signal is still 1)" or "the coupler has not extended in place (the retracted-in-place signal is 0, and the extended-in-place signal is 0)", and the coupler extension command (high level valid) output stops.

[0152] If the forced next-step signal on the monitor is received, the coupler extension command (level, high level valid) is output again through the input / output control unit, and the judgment of the coupler extension in-place signal continues to be executed.

[0153] If the end-of-coupling signal on the monitor is received, the coupling process is exited, the coupler extension command output stops, and the process returns to the start-of-coupling signal step. All current output commands are cleared, and the current state is maintained (the coupler may be at any position during the extension process).

[0154] The input / output control unit stops outputting the locking release command (high level for opening, low level for locking).

[0155] After the input / output control unit stops outputting the locking release command, a 10-second timer is started. If the coupler locking in-place signal (high level valid) feedback is received within the specified time, the status displayed on the monitor changes to a green prompt, and the next step is carried out; if the coupler locking in-place signal feedback is not received within the specified time, the execution stops, and at the same time, the status displayed on the monitor changes to a red prompt. At the same time, the human-machine interface reports "the coupler is not locked (the unlocked-in-place signal is 1)" or "the coupler is not locked in place (the unlocked-in-place signal is 0, and the locked-in-place signal is 0)", and the locking release command (high level for opening, low level for locking) is output through the input / output control unit.

[0156] If the forced next-step signal on the monitor is received, the input / output control unit stops outputting the locking release command again, and the judgment of the coupler locking in-place signal continues to be executed.

[0157] If the end-of-coupling signal on the monitor is received, the coupling process is exited, and the process returns to the start-of-coupling signal step. All current output commands are cleared, and the current state is maintained (at this time, since the coupler is retracted to the low-level locked state, it will automatically return to the locked state after the command is revoked).

[0158] A 10-second timer is started. If the input / output control unit detects the mechanical hook decoupling in-place signal (high level valid), the status displayed on the monitor changes to a green prompt, and the coupling preparation ready signal state is entered.

[0159] Otherwise, the display status changes to a red prompt, and the human-machine interface reports "the coupler uncoupling is not in place". The mechanical coupler uncoupling handle on the mechanical coupler can be operated, and then the mechanical coupler uncoupling signal judgment is continued.

[0160] If the end coupling signal on the display is received, the coupling process is exited, and the process returns to the start coupling signal step. All current output instructions are cleared, and the current state is maintained.

[0161] After entering the coupling ready signal, the mechanical coupler coupling signal entry flashes yellow to indicate, waiting for train coupling. If the end coupling signal on the display is received, the coupling process is exited, and the process returns to the start coupling signal step. All current output instructions are cleared, and the current state is maintained.

[0162] The driver selects the coupling and uncoupling mode signal (2 km / h) to control the train to move forward, impact the coupler, and detect the feedback of the mechanical coupler coupling in-place signal (high level valid). If the feedback is detected, the display status changes to a green prompt, and the next step is carried out; otherwise, continue to wait.

[0163] After a 2s delay, the input / output control unit outputs an air pipe opening instruction (high level valid).

[0164] After the input / output control unit outputs the air pipe opening instruction, a 10s timing is carried out. If the air pipe opening signal (high level valid) feedback is received within the specified time, the display status changes to a green prompt, and the next step is carried out; if the air pipe opening signal feedback is not received within the specified time, the execution stops downward. At the same time, the display status changes to a red prompt, reporting "the air pipe opening is not in place", and the input / output control unit stops outputting the air pipe opening instruction (high level valid).

[0165] If the forced next step signal on the display is received, the input / output control unit outputs the air pipe opening instruction (high level valid) again, and continues to execute the air pipe opening signal judgment.

[0166] If the end coupling signal on the display is received, the coupling process is exited, and the process returns to the start coupling signal step. All current output instructions are cleared, and the current state is maintained.

[0167] After a 2s delay, the input / output control unit stops outputting the air pipe opening instruction (high level valid).

[0168] The input / output control unit outputs an electrical connector connection instruction (high level valid).

[0169] After the input / output control unit outputs the electrical connector connection instruction, a 30-second timer is started. If the signal feedback indicating that the electric hook has extended in place (high level is valid) is received within the specified time, the status displayed on the monitor changes to a green prompt, and the next step is carried out; if the signal feedback indicating that the electric hook has extended in place is not received within the specified time, the status displayed on the monitor changes to a red prompt, an alarm of "the electric hook connection is not in place" is reported, and the input / output control unit is stopped from outputting the electrical connector connection instruction (high level is valid).

[0170] If the forced next step signal on the monitor is received, the input / output control unit outputs the electrical connector connection instruction (high level is valid) and continues to execute the judgment of the signal indicating that the electric hook has extended in place.

[0171] If the end connection signal on the monitor is received, the connection process is exited, the process returns to the step of the start connection signal, all current output instructions are cleared, and the current state is maintained.

[0172] After a 2-second delay, the output of the electrical connector connection instruction (high level is valid) is stopped;

[0173] A 5-second timer is started. If the signal feedback indicating the completion of the connection (high level is valid) is received within the specified time, the signal indicating the completion of the connection is displayed after a 2-second delay. If the signal feedback indicating the completion of the connection is not received within the specified time, the status displayed on the monitor changes to a red prompt, and the input / output control unit outputs the electrical connector connection instruction (high level is valid).

[0174] If the forced next step signal on the monitor is received, the input / output control unit stops outputting the electrical connector connection instruction (high level is valid) and continues to execute the judgment of the signal indicating the completion of the connection.

[0175] If the end connection signal on the monitor is received, the connection process is exited, the input / output control unit stops outputting the electrical connector connection instruction (high level is valid), the process returns to the step of the start connection signal, all current output instructions are cleared, and the current state is maintained.

[0176] After the connection is completed, the display interface jumps to the traction main interface / brake main interface after a 2-second delay.

[0177] In some embodiments, the coupler control further includes:

[0178] Judge the rescue signal. If the rescue signal is valid, when performing coupler control, it only executes up to the step of the connection preparation ready signal and stops executing downward.

[0179] Specifically, when the vehicle is in the mode of detecting the rescue switch rescue position signal (a high-level signal lasting for more than 200 milliseconds is valid) for the rescue signal or the mode of detecting the rescued position signal of the rescue switch (a high-level signal lasting for more than 200 milliseconds is valid) for the rescued signal, when performing the coupling signal operation, it only executes until the coupling ready signal step and does not execute the subsequent control actions. After a 2-second delay, the display interface jumps to the traction main interface / braking main interface.

[0180] In some embodiments, automatic decoupling includes coupler control, lower cowl closing control, and upper cowl closing control. The central control unit forwards the instruction to the input / output control unit, and the input / output control unit automatically completes the decoupling control process.

[0181] In this embodiment, the closing of the upper cowl means the oblique retraction, horizontal retraction, and flipping of the upper cowl, and the closing of the lower cowl means the oblique retraction and flipping of the lower cowl.

[0182] To prevent factors such as short circuits caused by the exposure of the electric coupler in rainy days, when decoupling, the coupled trains should perform the decoupling action synchronously. The decoupling instruction is issued through the train-level bus (only the coupled end of the train can issue the decoupling instruction to the train-level bus, and the decoupling instruction of the non-coupled end cannot be sent to the train-level bus). After the coupled-end train of the reconnected train receives the instruction from the coupled end of the other train, the display interface jumps to the start decoupling signal interface to perform the decoupling operation synchronously.

[0183] In some embodiments, the coupler control for automatic decoupling includes:

[0184] Judge the start decoupling signal. If the start decoupling signal is valid and the vehicle speed is lower than the preset speed, output the instruction to retract the electric coupler through the input / output control unit, and start timing for a preset time. If the feedback signal of the electric coupler retracting to the in-place position is received within the specified time, proceed to the next step; if the feedback signal of the electric coupler retracting to the in-place position is not received within the specified time, stop executing downward;

[0185] When the feedback signal of the electric coupler retracting to the in-place position is detected, after a preset time delay, cancel the instruction to retract the electric coupler output by the input / output control unit, and then output the instruction to close the air pipe through the input / output control unit, and start timing for a preset time. If the feedback signal of the air pipe closing is received within the specified time, proceed to the next step; if the feedback signal of the air pipe closing is not received within the specified time, stop executing downward;

[0186] When the feedback signal of the air pipe closing is detected, proceed to the next step;

[0187] Start timing for a preset time. If the feedback signal of the mechanical coupler decoupling is received within the specified time, after a preset time delay, cancel the instruction to close the air pipe output by the input / output control unit, and then enter the decoupling ready signal and wait for the train to decouple; if the feedback signal of the mechanical coupler decoupling is not received within the specified time, stop executing downward;

[0188] The input / output control unit outputs a locking release instruction and starts timing for a preset time. If the signal feedback indicating that the coupler unlocking is in place is received within the specified time, proceed to the next step; if the signal feedback indicating that the coupler unlocking is in place is not received within the specified time, stop executing downward and stop the input / output control unit from outputting the locking release instruction.

[0189] After the input / output control unit detects the signal indicating that the coupler unlocking is in place, continuously output the locking release instruction by the input / output control unit.

[0190] The input / output control unit outputs a coupler retraction instruction and starts timing for a preset time. If the signal feedback indicating that the coupler retraction is in place is received within the specified time, proceed to the next step; if the signal feedback indicating that the coupler retraction is in place is not received within the specified time, stop executing downward and stop outputting the coupler retraction instruction.

[0191] The input / output control unit stops outputting the locking release instruction and starts timing for a preset time. If the signal feedback indicating that the coupler locking is in place is received within the specified time, proceed to the next step; if the signal feedback indicating that the coupler locking is in place is not received within the specified time, stop executing downward and output the locking release instruction through the input / output control unit.

[0192] Specifically, when the driver operates the start decoupling signal on the coupler end display and the vehicle speed is lower than 5 km / h, the input / output control unit outputs a retract electric coupler instruction (high level is valid).

[0193] After the input / output control unit outputs the retract electric coupler instruction, start timing for 10 s. If the signal feedback indicating that the electric coupler retraction is in place (high level is valid) is received within the specified time, proceed to the next step; if the signal feedback indicating that the electric coupler retraction is in place is not received within the specified time, stop executing downward, the display status changes to a red prompt, and the input / output control unit's output of the retract electric coupler instruction (high level is valid) is cancelled.

[0194] If the forced next step signal on the display is received, output the retract electric coupler instruction (high level is valid) again through the input / output control unit and continue to judge the signal indicating that the electric coupler retraction is in place.

[0195] If the end decoupling signal on the display is received, exit the decoupling process and return to the start decoupling signal step.

[0196] When the signal indicating that the electric coupler retraction is in place (high level is valid) is detected, the display status changes to a green prompt. After a 2 s delay, cancel the input / output control unit's output of the retract electric coupler instruction (high level is valid), and then output a close air pipe instruction (high level is valid) through the input / output control unit.

[0197] After the input / output control unit outputs an air pipe closing instruction, a 10-second timer is started. If the air pipe closing signal (high level valid) feedback is received within the specified time, the next step is carried out; if the air pipe closing signal feedback is not received within the specified time, the execution stops, the status displayed on the monitor changes to a red prompt, and the air pipe closing instruction (high level valid) output by the input / output control unit is cancelled.

[0198] If the forced next step signal on the monitor is received, the air pipe closing instruction (high level valid) is output again through the input / output control unit, and the air pipe closing signal judgment continues to be executed.

[0199] If the end of decoupling signal on the monitor is received, the decoupling process is exited and the start of decoupling signal step is returned to.

[0200] When the air pipe closing signal (high level valid) is detected, the status displayed on the monitor changes to a green prompt.

[0201] A 10-second timer is started. If the mechanical hook decoupling signal (high level valid) feedback is received within the specified time, the status displayed on the monitor changes to a green prompt. After a 2-second delay, the air pipe closing instruction (high level valid) output by the input / output control unit is cancelled, and then the decoupling ready signal is entered, waiting for the train to decouple.

[0202] If the mechanical hook decoupling signal (high level valid) feedback is not received within the specified time, the execution stops, the status displayed on the monitor changes to a red prompt, the mechanical hook decoupling handle on the mechanical hook can be operated, and then the mechanical hook decoupling signal judgment continues to be executed.

[0203] If the end of decoupling signal on the monitor is received, the coupling process is exited, the air pipe closing instruction (high level valid) output by the input / output control unit is cancelled, and the start of decoupling signal step is returned to.

[0204] The input / output control unit outputs a lock release instruction (high level for opening, low level for locking).

[0205] After the input / output control unit outputs a lock release instruction, a 10-second timer is started. If the coupler unlocking in-place signal (high level valid) feedback is received within the specified time, the status displayed on the monitor changes to a green prompt, and the next step is carried out; if the coupler unlocking in-place signal feedback is not received within the specified time, the execution stops, the status displayed on the monitor changes to a red prompt at the same time, the human-machine interface reports a "coupler not unlocked" or "coupler not unlocked in place" fault at the same time, and the lock release instruction output by the input / output control unit is stopped.

[0206] If the forced next step signal on the monitor is received, the lock release instruction is output again through the input / output control unit, and the coupler unlocking in-place signal judgment continues to be executed.

[0207] If the decoupling signal is received on the display, exit the coupling process, return to the start decoupling signal step, clear all current output instructions, and maintain the current state (at this time, since the coupler shrinks to a low-level lock, it will automatically return to the locked state after the instruction is revoked).

[0208] After the input / output control unit detects the coupler unlocking in-place signal (high level is valid), the status on the display changes to a green prompt, and the input / output control unit continuously outputs the locking and unlocking instruction (high level is open, low level is locked).

[0209] The input / output control unit outputs the coupler retraction instruction (level, high level is valid).

[0210] After the input / output control unit outputs the coupler retraction instruction, a 10s timer is started. If the coupler retraction in-place signal (high level is valid) feedback is received within the specified time, the status on the display changes to a green prompt and the next step is carried out; if the coupler retraction in-place signal feedback is not received within the specified time, the execution stops, the status on the display changes to a red prompt, and the human-machine interface reports "the coupler has not retracted (the extended in-place signal is still 1)" or "the coupler retraction is not in place (the retracted in-place signal is 0, and the extended in-place signal is 0)", and the coupler retraction instruction (high level is valid) output stops.

[0211] If the forced next step signal is received on the display, the input / output control unit outputs the coupler retraction instruction (level, high level is valid) again and continues to judge the coupler extension in-place signal.

[0212] If the decoupling signal is received on the display, exit the coupling process, stop outputting the coupler retraction instruction, return to the start decoupling signal step, clear all current output instructions, and maintain the current state (the coupler may be at any position during the extension process).

[0213] The input / output control unit stops outputting the locking and unlocking instruction (high level is open, low level is locked).

[0214] After the input / output control unit stops outputting the locking and unlocking instruction, a 10s timer is started. If the coupler locking in-place signal (high level is valid) feedback is received within the specified time, the status on the display changes to a green prompt and the next step is carried out; if the coupler locking in-place signal feedback is not received within the specified time, the execution stops, the status on the display changes to a red prompt, and the human-machine interface reports "the coupler is not locked (the unlocked in-place signal is 1)" or "the coupler locking is not in place (the unlocked in-place signal is 0, and the locked in-place signal is 0)", and the input / output control unit outputs the locking and unlocking instruction (high level is open, low level is locked).

[0215] If a forced next-step signal is received on the display, the output of the lock release instruction is stopped again through the input / output control unit, and the judgment of the coupler lock-in place signal continues to be executed.

[0216] If an end-of-unhooking signal is received on the display, the unhooking process is exited, the process returns to the start-of-unhooking signal step, all current output instructions are cleared, and the current state is maintained.

[0217] After entering the unhooking ready signal process, the unhooking control display interface displays the signal to close the hood and the confirmation signal button, and the button is hidden before this step.

[0218] In some embodiments, the control of closing the lower hood during automatic unhooking includes:

[0219] The input / output control unit outputs a signal to unlock the brake of the lower hood retraction motor, sends a forward motor instruction to the driver of the lower hood retraction motor, and starts a preset time countdown. If a feedback signal indicating that the lower hood retraction is closed in place is received within the specified time, the output of the signal to unlock the brake of the lower hood retraction motor is stopped and the next step is carried out;

[0220] The input / output control unit outputs a signal to unlock the brake of the lower hood flipping motor, sends a forward motor instruction to the lower hood flipping motor, and starts a preset time countdown. If a feedback signal indicating that the lower hood flipping is closed in place is received within the specified time, the output of the signal to unlock the brake of the lower hood flipping motor is stopped and the next step is carried out.

[0221] Specifically, the input / output control unit outputs a fourth motor brake unlock signal and an eighth motor brake unlock signal (1 = unlock, 0 = brake) and sends forward motor instructions to the fourth motor driver and the eighth motor driver respectively through CAN communication, and starts an 8s countdown. If a feedback signal indicating that the lower hood retraction is closed in place (high level valid) is received within the specified time, the status on the display changes to a green prompt, the output of the fourth motor brake unlock signal and the eighth motor brake unlock signal is stopped, and the next step is carried out; if a feedback signal indicating that the lower hood retraction is closed in place is not received within the specified time, the execution stops downward, the status on the display changes to a red prompt (reporting a fault) at the same time, and the forward motor instruction sending is stopped.

[0222] If a forced next-step signal is received on the display, the action and judgment of the upper hood retraction closed in place signal are executed again;

[0223] If an end-of-hooking signal is received on the display, the hooking process is exited, the process returns to the start-of-hooking signal step, all output instructions are cleared, and the current state is maintained.

[0224] The input / output control unit outputs the second motor brake unlock signal and the sixth motor brake unlock signal (1 = unlock, 0 = brake), and sends the motor forward command to the second motor driver and the sixth motor driver respectively through CAN communication, and starts an 8-second timing. If the signal feedback indicating that the lower hood has been flipped and closed in place (high level valid) is received within the specified time, the status displayed on the monitor will change to a green prompt, the output of the second motor brake unlock signal and the sixth motor brake unlock signal will be stopped, and the next step will be carried out; if the signal feedback indicating that the lower hood has been flipped and closed in place is not received within the specified time, the execution will stop downward. At the same time, the status displayed on the monitor will change to a red prompt (reporting a fault), and the motor forward command will be stopped from being sent.

[0225] If the forced next step signal on the monitor is received, the action and judgment of the signal indicating that the lower hood has been flipped and closed in place will be executed again;

[0226] If the end coupling signal on the monitor is received, the coupling process will be exited, and the process will return to the start coupling signal step, clearing all output commands and maintaining the current state.

[0227] In some embodiments, the control for closing the upper hood during automatic decoupling includes:

[0228] The input / output control unit outputs the brake unlock signal for the upper hood retracting obliquely motor, sends the motor forward command to the driver of the upper hood retracting obliquely motor, and starts a preset time timing. If the signal feedback indicating that the upper hood has been retracted obliquely and closed in place is received within the specified time, the output of the brake unlock signal for the upper hood retracting obliquely motor will be stopped and the previous step will be carried out;

[0229] The input / output control unit outputs the brake unlock signal for the upper hood retracting and flipping horizontally motor, sends the motor forward command to the upper hood retracting and flipping horizontally motor, and starts a preset time timing. If the signal feedback indicating that the upper hood has been flipped and closed in place is received within the specified time, the output of the brake unlock signal for the upper hood retracting and flipping horizontally motor will be stopped and the previous step will be carried out.

[0230] Specifically, the input / output control unit outputs the third motor brake unlock signal and the seventh motor brake unlock signal (1 = unlock, 0 = brake), and sends the motor forward command to the third motor driver and the seventh motor driver (or the main driver) respectively through CAN communication. After waiting for 10 s, if the signal feedback indicating that the upper hood has been retracted obliquely and closed in place (high level valid) is monitored, the status displayed on the monitor will change to a green prompt, the output of the third motor brake unlock signal and the seventh motor brake unlock signal will be stopped, and the next step will be carried out; otherwise, the execution will stop downward. At the same time, the status displayed on the monitor will change to a red prompt (reporting a fault), and the motor forward command will be stopped from being sent;

[0231] If the forced next step signal on the monitor is received, the action and judgment of the signal indicating that the upper hood has been retracted obliquely and closed in place will be continued;

[0232] If the end-of-coupling signal is received on the display, exit the coupling process, return to the start-of-coupling signal step, clear all output commands, and maintain the current state.

[0233] The input / output control unit outputs the first motor brake unlock signal and the fifth motor brake unlock signal (1 = unlock, 0 = brake), and sends the motor forward command to the first motor driver and the fifth motor driver (or the main driver) respectively through CAN communication. After waiting for 8 s, if the signal indicating that the upper hood has retracted, flipped, and closed in place (high level valid) is detected, the status on the display changes to a green prompt, stop outputting the first motor brake unlock signal and the fifth motor brake unlock signal, and proceed to the next step; otherwise, stop executing downward, at the same time, the status on the display changes to a red prompt (reporting a fault), and stop sending the motor forward command.

[0234] If the forced next step signal is received on the display, continue to execute the action and judgment of the signal indicating that the upper hood has retracted, flipped, and closed in place.

[0235] If the end-of-coupling signal is received on the display, exit the coupling process, return to the start-of-coupling signal step, clear all output commands, and maintain the current state.

[0236] After the decoupling is completed, the display interface jumps to the traction main interface / braking main interface after a 2-second delay.

[0237] In some embodiments, when the driver's key is inserted, click the start-of-coupling signal or the start-of-decoupling signal through the coupling and decoupling signal screen, and the coupling and decoupling control air switch (network control starts coupling or starts decoupling). The coupling and decoupling processes are interlocked.

[0238] The coupling and decoupling process is restricted as follows.

[0239] The coupling signal / decoupling signal process is continuous and does not allow execution from an intermediate step; the process displayed on the human-machine interface is also continuous and proceeds sequentially according to the steps that have been completed.

[0240] When the coupling and decoupling control air switch signal (high level valid) is detected to be at a low level, the network immediately exits the coupling signal / decoupling signal control, and cancels the output of the input / output control unit for the coupler retraction command, the locking and unlocking command, the coupler extension command, the hood opening command (high level valid), the hood closing command (high level valid), the hood lock opening command (high level valid), the air pipe opening command (high level valid), the air pipe closing command (high level valid), the electric coupler extension command (high level valid), the electric coupler retraction command (high level valid), and the coupling and decoupling control power supply signal (high level valid), and returns to the initial state of the coupling signal / decoupling signal.

[0241] The present application also provides a rail vehicle, which adopts the above network control method for the opening and closing mechanism and the coupler. Based on the electric scheme of up-and-down opening and closing and the retractable front coupler, an automatic control scheme for train decoupling and coupling is adopted to meet the coupling and decoupling functions of the vehicle.
