Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
Fig. 1 shows a flow chart of a method for controlling automatic uncoupling of a train according to an embodiment of the invention. In step S101, an operation instruction to start unlinking issued by a user is received in the automatic unlink operation interface. The operation Interface generally refers to a Human Machine Interface unit (HMI) on a train, which is also called a Human Machine Interface (HMI) for short, and is a medium for interaction and information exchange between a system and a user, and realizes conversion between an internal form of information and a Human acceptable form. Human-machine interfaces exist in all fields participating in human-machine information exchange. The man-machine interface product consists of two parts of hardware and software, wherein the hardware part comprises a processor, a display unit, an input unit, a communication interface, a data storage unit and the like. The operation interface in the invention can transmit instructions and display the states of each part of the train. In this step, the user issues an instruction to start the disconnection, and then the operation interface receives the instruction.
After receiving the operation instruction for starting disconnection, the operation interface acquires the vehicle running speed in response to the operation instruction for starting disconnection in step S102, and enters an automatic disconnection operation process to execute a series of operation instructions when the vehicle running speed is lower than a certain speed threshold. In order to ensure the safety of the train, the train disconnection should be performed at a low speed of the train. Therefore, before the train disconnection is performed, it is necessary to acquire the current running speed of the train so as to start the train disconnection process in the case where the train is at a low speed. In one embodiment, the speed threshold for the train is 5 km/h. When the train speed is lower than 5km/h, the automatic train disconnection operation process can be entered, and then a series of operation instructions are executed.
After entering the automatic train disconnection operation flow, in step S103, after a predetermined time has elapsed, it is detected whether state feedback information of each operation instruction in the automatic disconnection operation flow is successfully executed is received. The automatic decoupling process involves execution of a plurality of operation instructions and execution feedback, and whether the current operation instruction is executed successfully needs to be detected when each operation instruction is executed. If the execution is successful, the next operation instruction continues to be executed. And if the current operation instruction is not executed successfully, reporting the feedback information, and stopping executing the current operation instruction or repeatedly executing the current operation instruction.
Finally, in step S104, it is determined that the automatic decoupling operation is finished based on the reception of the state feedback information, and a return from the automatic decoupling operation interface to the traction or brake master interface is guided. And if the disconnection is completed or an instruction for finishing the disconnection is received, returning to the traction or braking main interface. And ending the train disconnection process.
It should be noted that in the process of Train disconnection, many aspects of cooperation are needed, and the aspects related to the disconnection process include a Train Control and monitoring System (Train Control and Management System, TCMS for short), a Central Control Unit (CCU for short), a Human Machine Interface Unit (HMI for short), and a Digital Input Output Module (DXM for short). The train control and monitoring system is used for controlling and monitoring the train. A Central Control Unit (CCU) is used for coordination and Control. The digital input output module DXM is used to input and output commands or other information.
Fig. 2 shows an uncoupling operator interface diagram for a method of controlling automatic uncoupling of a train according to an embodiment of the present invention. As shown in fig. 2, the unlink operation interface includes two buttons, which are respectively a start unlink and an end unlink. The device comprises nine state indication interfaces and corresponding keys, wherein the state indication interfaces are respectively completed by disconnection preparation, electric hook return to the right position, air pipe closing, mechanical hook disconnection, disconnection preparation, hood lock opening, hood closing and disconnection.
And after the disconnection is started by pressing, entering an automatic disconnection operation process and starting to execute a plurality of operation instructions. And when the operation instruction is executed and the disconnection is finished by pressing, the automatic disconnection is finished, the automatic disconnection process of the train is quitted, and the disconnection starting step is returned.
When any one of the disconnection preparation, the electric hook returning to the right position, the air pipe closing, the mechanical disconnection, the disconnection preparation, the hood lock opening, the hood closing and the disconnection completion is successfully executed, the ground color corresponding to the successfully executed operation step is changed into the first color. And when any one of the executions fails, the color changes to the second color. In one embodiment, the first color is green and the second color is red.
Fig. 3a and 3b show detailed flowcharts of a method for controlling automatic train uncoupling according to an embodiment of the present invention.
According to the method for controlling the train to automatically disconnect, a driver only needs to click on the HMI disconnection interface to enter the disconnection process, the subsequent whole disconnection process can be displayed on the HMI interface in real time, whether each link or device acts in place or not can be fed back correspondingly, green is displayed when the links or devices act in place, red is displayed when the links or devices do not act in place, and therefore the fault position can be located conveniently.
As shown in fig. 3a and 3b, in step S301, the disconnection is started. The driver operates the display to initiate unlink, and in step S302, it is determined whether the vehicle speed is less than 5 km/h. If the vehicle speed is greater than 5km/h, the process returns to step S301. If the vehicle speed is lower than 5km/h, the next command can be output through the digital input and output module DXM. The process proceeds to step S303, where the digital input/output module DXM outputs a retract hook command.
After the digital input/output module DXM outputs the electric hook return command, in step S306, it is determined whether the electric hook return to the place is completed within 10S. If the hook return to the position feedback is not received within the specified time, the process proceeds to step S307, the downward execution is stopped, the display status changes to red, and in step S308, the digital input/output module DXM cancels the output of the hook return command. If the electric hook return to position feedback of step S309 is received within the prescribed time, the next step is performed.
If the instruction for forcing the next step in step S304 is received, step S303 is repeated again, and the digital input/output module DXM outputs the instruction for retracting the electrical hook, and continues to determine whether the electrical hook is retracted in place. If an instruction to end the decoupling is received in step S305, the decoupling process exits, and the process returns to the beginning of decoupling in step S301.
When the feedback information of the return of the electric hook to the in-place state in the step S309 is detected, the display state is changed to green, the process proceeds to the step S310 after the delay of 2S, the digital input output module DXM cancels the output of the return electric hook instruction, and then the air pipe closing instruction is output through the digital input output module DXM in the step S311.
After the digital input/output module DXM outputs the air tube closing command, the timer counts 10S, and in step S314, it is determined whether the air tube is closed within a predetermined time of 10S. If the air tube closing feedback information of step S317 is received within the prescribed time, the next step is performed. If the air pipe closing feedback is not received within the specified time, the step S315 is entered, the downward execution is stopped, the display state on the display is changed to a red prompt, and the step S316 is entered, and the DXM cancels the output of the air pipe closing instruction.
And if an instruction of forcing the next step in the step S312 on the display is received, the step S311 is entered, the air pipe closing instruction is output again through the digital input/output module DXM, and the judgment of the feedback information of whether the air pipe is closed is continuously executed. If the instruction of ending the unlink of the step S313 on the display is received, the unlink flow exits and returns to the unlink starting step of the step S301.
When the air duct close feedback information of step S317 is detected, a display state change to green cue is displayed on the display. Step S318 is then entered to determine whether the mechanical hook is in place within 10S.
If the feedback information of mechanical hooking disconnection in the step S322 is received within the specified time of 10S, the display state changes to green, the process proceeds to the step S323 after the time delay of 2S, and the digital input output module DXM cancels the output of the air pipe closing instruction. Then, the process proceeds to an uncoupling preparation step in step S324, and waits for the train to be uncoupled.
If the mechanical hook disconnection feedback is not received within the specified time of 10S, that is, the process goes to step S319, the downward execution is stopped, a red prompt is displayed on the display, and the judgment of the feedback information on whether the mechanical hook is disconnected or not can be continuously executed by operating the mechanical hook disconnection handle on the mechanical hook.
If the instruction of ending the disconnection of the step S320 on the display is received, the disconnection process exits, the step S321 is entered, the digital input output module DXM cancels the instruction of closing the air pipe, and the step S301 of starting the disconnection is returned to.
After the process of step S324 of preparing for disconnection, the disconnection control display interface displays the closing hood and the confirmation button, and both buttons are hidden before this step.
The driver controls the train to walk off the train and disconnect, clicks to close the hood and confirms the forced closing step of the step S325, and then the step S326 is entered, and an instruction for opening the hood lock is outputted through the digital input output module DXM.
After the digital input/output module DXM outputs the instruction to open the head cover lock, the timing is performed for 5S, and the process proceeds to step S329 to determine whether the head cover lock is opened within 5S. If the feedback information of the open of the hood lock of step S322 is received within the prescribed time, the next step is performed. If the hood lock opening feedback is not received within the specified time, the process goes to step S330, the downward execution is stopped, a red prompt is displayed on the display, and the process goes to step S331, in which the digital input/output module DXM cancels the output of the instruction for opening the hood lock.
If the next step of forcing command of step S327 on the display is received, step S326 is performed again, and the digital input/output module DXM outputs a command to open the head lock, and continues to execute the feedback information judgment of whether the head lock is opened. If the instruction of ending the unlink in step S328 on the display is received, the unlink process is exited and the unlink process returns to the step of starting the unlink in step S301.
After detecting the successful opening of the hood lock in step S332, displaying a green indication on the display, and then proceeding to step S333, outputting a hood closing command through the digital input/output module DXM.
In step S333, after the digital input/output module DXM outputs the closing command, the timing is performed for 15 seconds, and the process proceeds to step S337 to determine whether the hood is closed within 15 seconds. If the headgear closing feedback of step S340 is received within the prescribed time of 15S, the next step is performed. If the hood closing feedback is not received within the specified time, the process proceeds to step S338, the downward execution is stopped, a red prompt is displayed on the display, and the process proceeds to step S339, in which the digital input/output module DXM cancels the output of the hood closing command.
If the forced next instruction of step 334 on the display is received, step 333 is entered again, and the digital input/output module DXM outputs the instruction to close the head cover, and continues to execute the judgment of the feedback information of whether the head cover is closed. If receiving the end unlink instruction of step S335 on the display. The disconnection process is exited, step S336 is entered, and the digital input output module DXM cancels the output of the open hood lock command, and then returns to the disconnection starting step of step S301.
When the hood closing information of the step S340 is detected, the display state is changed to green, and after 2 seconds of delay, the operation proceeds to a step S341, and the digital input/output module DXM cancels and outputs a hood lock opening and closing instruction.
In step S341, the digital input/output module DXM cancels the output switch head lock command and performs timing for 5 seconds. And proceeds to step S345 to determine whether the hood lock is closed within 5S. If the hood lock closing feedback of step S348 is received within the prescribed time, the next step is performed. If the hood lock closing feedback is not received within the predetermined time, the process proceeds to step S346, the downward execution is stopped, a red indication is displayed on the display, and the process proceeds to step S347, where a command to open and close the hood lock is output through the digital input/output module DXM.
If the next step of forcing instruction in step S342 on the display is received, step S341 is entered again, and the digital input/output module DXM cancels the instruction to switch on/off the head cover lock, and continues to determine whether the head cover lock is closed.
If the instruction of ending the decoupling in step S343 on the display is received, the decoupling process exits, and step S344 is entered, where the digital input output module DXM cancels the instruction of outputting the closing hood and the digital input output module DXM cancels the instruction of outputting the opening hood lock. And then returns to the initial disconnection step of step S301.
When the hood lock is detected to be closed, a display state is changed to green, the step S349 is carried out after 2S of delay, and the digital input/output module DXM cancels and outputs a hood closing instruction. Then, the process proceeds to step S350, and the completion of the disconnection is displayed on the operation interface.
In step S350, after the disconnection is completed, the operation display is delayed by 2 seconds, and the process proceeds to step S351, where the display interface jumps to the traction main interface or the brake main interface.

and outputting a return electric hook instruction by the digital input and output module.
And if the state feedback information that the electric hook returns to the place is received within the preset time, carrying out a subsequent disconnection operation instruction.
And if the state feedback information that the electric hook returns to the place is not received within the preset time, stopping executing any disconnection operation instruction, changing the display state into a second color prompt on the automatic disconnection operation interface, and simultaneously canceling the electric hook returning instruction output by the digital input and output module.
And if an instruction for forcing the next disconnection operation sent by the automatic disconnection operation interface is received, sending an electric hook return instruction again through the digital input/output module so as to continuously execute the state judgment whether the electric hook returns to the place or not.
From the above, it can be seen that the medium for inputting instructions is a digital output input module. And after the operation instruction is input, countdown of preset time is carried out, and if feedback information of success of the operation instruction is received in the countdown, a subsequent disconnection operation instruction is carried out. If the feedback information of successful execution of the operation instruction is not received within the preset time, stopping executing any operation instruction, and changing the display state to a second color prompt on the automatic unlink operation interface, namely indicating that the operation step is unsuccessful, so as to prompt the user. And simultaneously, canceling the current operation instruction output by the digital input and output module.
If an instruction for forcing the next step is received when the operation instruction is executed, the current operation instruction is sent out again through the digital input and output module, and the step of judging whether the current operation instruction is in place is continuously executed. If an instruction for ending the unlink is received in the execution process, returning to the operation instruction for starting the unlink immediately.
The guidance module 404 is configured to determine that an automatic uncoupling operation is complete based on receipt of the status feedback information and to direct a return from the automatic uncoupling operation interface to the traction or braking home interface. And determining the end of the automatic decoupling operation based on the receiving of the state feedback information, and guiding the automatic decoupling operation interface to return to the step of dragging or braking the main interface, wherein if the automatic decoupling operation interface fails, the failure information is indicated by colors.
