[0052] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0053] In the process of implementing this application, the inventor found that after the existing train returns to the depot, cleaning staff generally enter the working area, manually activate the train, turn on the door lighting, etc., and then manually shut down the train after cleaning is completed. However, this method requires cleaning staff to perform a series of operations such as activating the train, which has high requirements for cleaning staff and increases the possibility of cleaning staff misoperation, increasing the risk of train cleaning. If the cleaning staff forgets to shut down the train, the train battery will be depleted and the train will not be able to activate normally.

[0054] In response to the above problems, the present application provides a cleaning mode control method and a train, the method is used to control the cleaning mode of the train; the outside of the train includes a cleaning mode confirmation switch, and the inside includes a controller; the method includes: if the cleaning mode confirmation switch is activated and the train is activated, then after the controller is powered on, the controller determines whether to enter the cleaning mode according to the pantograph state; if entering the cleaning mode, the controller activates the lighting system of the train, activates the door enable on both sides, and turns on the air conditioner; if a trigger to exit the cleaning mode is obtained, the controller controls the train to exit the cleaning mode. The method provided by the present application realizes automatic control of the cleaning mode of the train, does not require cleaning personnel to participate in the control, and avoids the problem that the cleaning personnel forget to shut down the train, resulting in the train battery being depleted and unable to be activated normally.

[0055] This embodiment provides a cleaning mode control method, which is used to control the cleaning mode of a train.

[0056] The exterior of the train includes a cleaning mode confirmation switch, and the interior includes a controller.

[0057] 1. Cleaning mode confirmation switch

[0058] Cleaning mode confirmation switch Figure 1 As marked in 2, the cleaning staff uses the hexagonal tool key to open the control panel protective cover to expose the cleaning mode confirmation switch.

[0059] 2. Controller

[0060] The controller will collect train-related status information, including hard-wire status information collection and bus network data information collection.

[0061] Hard-wire status information is collected through the hard-wire control circuit, and the collected status includes train activation signal, lighting activation signal, door status signal, pantograph raising and lowering information and other signals.

[0062] The bus network data information is collected and sent through the communication network by various vehicle systems, including air conditioning status, doors, auxiliary power supply system, and passenger information system.

[0063] In addition, the controller is used to execute all steps performed by the controller in the cleaning mode control method provided in this embodiment, such as Figure 2 As shown, the cleaning mode control method provided in this embodiment is as follows:

[0064] 201. If the cleaning mode confirmation switch is activated and the train is activated, after the controller is powered on, the controller determines whether to enter the cleaning mode based on the pantograph status.

[0065] The cleaning mode confirmation switch can be activated by Figure 3The cleaning mode status signal acquisition circuit shown in FIG. 1 sends the activation information to the controller. For example, the cleaning staff inserts the cleaning mode key outside the vehicle. Figure 1 If the cleaning mode confirmation switch marked with 2 is turned on, the cleaning mode confirmation switch is considered to be activated. Figure 3 The cleaning mode status signal acquisition circuit shown in FIG. 1 sends the activation information to the controller.

[0066] The train activation process is completed through the auxiliary contacts of the cleaning mode relay 80-K02. Figure 4 The vehicle activation and shutdown control circuit shown is completed. After the train is activated, the controller inside the train will automatically be powered.

[0067] The controller determines whether to enter the cleaning mode according to the pantograph status as follows:

[0068] The controller detects whether the pantograph of the train is in the lowered position. If the pantograph is in the lowered position, the controller sends a pantograph raising command. If the controller determines during the delay detection whether the pantograph is raised normally and that the train is powered by the overhead line, it determines that the train has entered the cleaning mode; otherwise, it determines that the train has not entered the cleaning mode.

[0069] In addition, after the controller determines whether to enter the cleaning mode according to the pantograph status, if the cleaning mode is not entered, the controller issues a train shutdown command.

[0070] After issuing the train shutdown command, the controller will also confirm whether the train is powered off. If so, the train shutdown will be completed. If not, it is considered that the train cannot automatically exit the cleaning mode and the current state of the train will be maintained for maintenance personnel to handle.

[0071] In step 201, when the cleaning mode confirmation switch is activated, the train will first automatically complete the train activation. After the train is activated, the internal controller of the vehicle will automatically be powered on. When the controller is powered on and starts working, it will collect the status information of the cleaning mode relay activation. At this time, it can detect whether the pantograph of the train is in the lowered position. If the pantograph is in the lowered position, the controller sends a pantograph raising command (based on Figure 5 The pantograph control circuit shown completes the pantograph raising. After the pantograph raising command is issued, the controller will delay to detect whether the pantograph is raised normally, and detect whether the train obtains power supply from the overhead line, then judge to enter the cleaning mode, and execute step 202 and subsequent steps, otherwise, it is judged that the cleaning mode has not been entered, and the controller issues a train shutdown command (based on Figure 4 The vehicle activation and shutdown control circuit shown completes train shutdown).

[0072] 202, if entering the cleaning mode, the controller activates the lighting system of the train, activates the door enable on both sides, and turns on the air conditioner.

[0073] The implementation process of this step is as follows: when the train completes the high-voltage current receiving of the overhead line, the controller activates the lighting system of the train. The controller detects whether the lighting system is turned on through the light sensor inside the train. If it is detected that the lighting system is turned on, the door enable on both sides is activated and the air conditioner is turned on. If it is detected that the lighting system is not turned on, the controller issues a pantograph lowering command and a train shutdown command.

[0074] In specific implementation, after the controller issues a pantograph lowering command, the controller determines whether the pantograph has been lowered normally. If it has been lowered normally, the controller then issues a train shutdown command.

[0075] After issuing the train shutdown command, the controller will also confirm whether the train is powered off. If so, the train shutdown will be completed. If not, it is considered that the train cannot automatically exit the cleaning mode and the current state of the train will be maintained for maintenance personnel to handle.

[0076] The process of activating the door enable on both sides and turning on the air conditioner is as follows: the controller sends a door enable activation signal on both sides. If the controller receives the door enable activation status signal sent by all door controllers, the air conditioner is turned on. Otherwise, the controller sends a lighting shutdown command, a pantograph lowering command, and a train shutdown command.

[0077] In specific implementation, after the controller issues a pantograph lowering command, the controller determines whether the pantograph has been lowered normally. If it has been lowered normally, the controller then issues a train shutdown command.

[0078] After issuing the train shutdown command, the controller will also confirm whether the train is powered off. If so, the train shutdown will be completed. If not, it is considered that the train cannot automatically exit the cleaning mode and the current state of the train will be maintained for maintenance personnel to handle.

[0079] Among them, the process of turning on the air conditioner is: the controller sends a turn-on command to the air conditioning system and sets the air conditioning mode to automatic mode. The controller detects the proportion of air conditioners that have been turned on and in automatic mode. If the proportion of air conditioners that have been turned on and in automatic mode is not less than the proportion threshold, the controller controls the display screen outside the train to display the information that the train is in a cleaning state (such as the controller sends that the train has entered "cleaning mode" in the PIS (Passenger Information System, Passenger Information System), and controls the display screen outside the train to display the status information "The vehicle is being cleaned"). Otherwise, the controller issues an air conditioning shutdown command, a lighting shutdown command, a bow lowering command, and a train shutdown command.

[0080] For example, if the ratio threshold is 1 / 2, then if the ratio of air conditioners that are turned on and in automatic mode is not less than 1 / 2, the controller controls the display screen outside the train to display information that the train is in a clean state. Otherwise, the controller issues an air conditioner shutdown command, a lighting shutdown command, a pantograph lowering command, and a train shutdown command.

[0081] In specific implementation, if the proportion of air conditioners that are turned on and in automatic mode is less than the proportion threshold, the controller can directly issue air conditioner shutdown instructions, lighting shutdown instructions, bow lowering instructions, and train shutdown instructions. Alternatively, the air conditioner fault state can be sent to the ground control center first, and the ground control center decides whether to continue cleaning or exit. After receiving the decision to exit from the ground control center, the controller issues air conditioner shutdown instructions, lighting shutdown instructions, bow lowering instructions, and train shutdown instructions.

[0082] After the controller issues the pantograph lowering command, the controller determines whether the pantograph has been lowered normally. If it has been lowered normally, the controller then issues the train shutoff command.

[0083] After issuing the train shutdown command, the controller will also confirm whether the train is powered off. If so, the train shutdown will be completed. If not, it is considered that the train cannot automatically exit the cleaning mode and the current state of the train will be maintained for maintenance personnel to handle.

[0084] In addition, before the controller issues the lighting off command, it can also issue a door enable cancellation command and a door closing command, and then issue the lighting off command after confirming that all doors are closed. If there are doors that are not closed, it means that the train cannot automatically exit the cleaning mode and maintain the current state of the train for maintenance personnel to handle.

[0085] After the controller issues the pantograph lowering command, the controller determines whether the pantograph has been lowered normally. If it has been lowered normally, the controller then issues the train shutoff command.

[0086] After issuing the train shutdown command, the controller will also confirm whether the train is powered off. If so, the train shutdown will be completed. If not, it is considered that the train cannot automatically exit the cleaning mode and the current state of the train will be maintained for maintenance personnel to handle.

[0087] In step 202, after the train completes the contact network high voltage current collection, the controller activates the train lighting system (based on Figure 6 The lighting control circuit shown activates the lighting) and detects whether the lighting system is turned on through the light sensor inside the train. If it is detected that the lighting system is turned on, the door enable on both sides is activated and the air conditioner is turned on. If it is detected that the lighting system is not turned on, the controller issues a bow lowering command (based on Figure 5 The pantograph control circuit shown completes the pantograph landing) and the controller issues a train shutdown command (based on Figure 4The vehicle activation and shutdown control circuit shown completes train shutdown).

[0088] The process of activating the door enable on both sides and turning on the air conditioner is as follows: after the lighting system is turned on, the controller automatically sends a door opening enable signal on both sides (based on Figure 7 The controller will detect whether it has received the door enable activation status signal (transmitted through the network) sent by all door controllers. If it has received it, the air conditioner will be turned on. Otherwise, the controller will issue a lighting off command (based on Figure 6 The lighting control circuit shown in the figure turns off the lighting), and the controller issues a bow lowering command (based on Figure 5 The pantograph control circuit shown completes the pantograph landing) and the controller issues a train shutdown command (based on Figure 4 The vehicle activation and shutdown control circuit shown completes train shutdown).

[0089] The process of turning on the air conditioner is as follows: after the door opening enable signals on both sides are successfully sent, the controller sends a start command to the air conditioner system and sets the air conditioner mode to automatic mode. The controller then detects whether the air conditioner system sends a signal that the air conditioner is turned on and in automatic mode. If no less than 1 / 2 of the air conditioners in the entire train are successfully turned on, the controller sends a signal in the PIS system that the vehicle has entered "cleaning mode" and controls the display screen outside the vehicle to display the status information "the vehicle is being cleaned". Otherwise, the controller sends an air conditioner shutdown command and a lighting shutdown command (based on the Figure 6 The lighting control circuit shown in the figure turns off the lighting), and the controller issues a bow lowering command (based on Figure 5 The pantograph control circuit shown completes the pantograph landing) and the controller issues a train shutdown command (based on Figure 4 The vehicle activation and shutdown control circuit shown completes train shutdown).

[0090] The automatic entry control into the “cleaning mode” is implemented through steps 201 and 202 .

[0091] After executing step 202 , it is detected in real time whether a trigger for exiting the cleaning mode is obtained. If so, step 203 is executed.

[0092] Among them, the trigger for exiting the cleaning mode includes active triggering and passive triggering. If the cleaning mode confirmation switch is deactivated (for example, after the cleaning staff completes the vehicle cleaning, they pull out the cleaning mode key, and the cleaning mode confirmation switch is deactivated at this time), the controller determines that the trigger for exiting the cleaning mode is obtained, and it is an active trigger. If the high-voltage power supply of the train is lost, the controller determines that the trigger for exiting the cleaning mode is obtained, and it is a passive trigger.

[0093] That is, active triggering is when the cleaning staff actively exits after cleaning is completed. For example, after the cleaning staff finishes cleaning the vehicle, they turn the cleaning mode key from Figure 1 If the cleaning mode confirmation switch marked with 2 is pulled out, the cleaning mode confirmation switch is considered to be deactivated, and at this time, it is considered that the trigger for exiting the cleaning mode is obtained. Figure 3 The cleaning mode status signal acquisition circuit shown in the figure sends the acquired trigger of exiting the cleaning mode to the controller.

[0094] Passive triggering is a situation in which the cleaning process is passively exited due to loss of high pressure.

[0095] 203. If a trigger for exiting the cleaning mode is obtained, the controller controls the train to exit the cleaning mode.

[0096] Regardless of whether it is an active trigger or a passive trigger, once a trigger to exit the cleaning mode is obtained, the controller will control the train to exit the cleaning mode.

[0097] Specifically, the controller will control the train to exit the cleaning mode in the following process: the controller issues a door closing command. After the controller determines that all doors are closed, it issues a warm mode command for controlling the air conditioner to force the first duration, issues a lighting shutdown command after a first delay, issues a pantograph lowering command after a second delay, and issues a train shutdown command after detecting pantograph lowering status feedback. If the controller determines that not all doors are closed, or if no pantograph lowering status feedback is detected after issuing a pantograph lowering command, or if the controller is detected to be in control status after issuing a train shutdown command for a third duration, the current state of the train is maintained for maintenance personnel to step on the train for processing.

[0098] In addition, in the case of passive triggering, the controller can also trigger the pre-recorded voice broadcast inside the train (which can be broadcast in a loop), such as: due to the loss of high voltage, the vehicle will automatically shut down in 10 minutes. And after 10 minutes, the controller controls the train to exit the cleaning mode.

[0099] Among them, the first duration can be 3 minutes, the second duration can be 2 seconds, and the third duration can be 5 seconds.

[0100] For example, in the case of active triggering: after the cleaning staff completes the cleaning of the vehicle, they pull out the cleaning mode key. At this time, after the controller obtains the trigger to exit the cleaning mode, the controller cancels the door enable and issues a door closing command (based on Figure 7 The controller determines that all doors are closed and issues a command to control the air conditioner to force a warm mode for 3 minutes. After 3 minutes, the controller issues a lighting off command (based on the Figure 6 The lighting control circuit shown in the figure turns off the lighting), and 2 seconds later the controller issues a bow lowering command (based on Figure 5 The pantograph control circuit shown completes the pantograph lowering). If the controller detects the pantograph lowering status feedback, it issues a train shut-off command (based on Figure 4 The vehicle activation and shutdown control circuit shown completes train shutdown).

[0101] If the controller determines that not all doors are closed (which means the train cannot automatically exit cleaning mode), or if no pantograph lowering status feedback is detected after a pantograph lowering command is issued, or if the controller is detected to be in control status 5 seconds after a train shutdown command is issued, the current status of the train is maintained for maintenance personnel to handle.

[0102] For example, in the passive triggering situation, when the cleaning staff completes the cleaning of the train, the high voltage power supply of the train is lost, and the train will passively exit the cleaning mode. At this time, the controller obtains the trigger to exit the cleaning mode, and then the controller issues a door closing command (based on Figure 7 The controller determines that all doors are closed and issues a command to control the air conditioner to force a warm mode for 3 minutes. After 3 minutes, the controller issues a lighting off command (based on the Figure 6 The lighting control circuit shown in the figure turns off the lighting), and 2 seconds later the controller issues a bow lowering command (based on Figure 5 The pantograph control circuit shown completes the pantograph lowering). If the controller detects the pantograph lowering status feedback, it issues a train shut-off command (based on Figure 4 The vehicle activation and shutdown control circuit shown completes train shutdown).

[0103] Automatic exit control of the “cleaning mode” is implemented through step 203 .

[0104] The cleaning mode control method provided in this embodiment is implemented by a cleaning mode confirmation switch located outside the train, a controller located inside the train, and other equipment in the train. The cleaning mode control method provided in this embodiment is activated by the cleaning mode confirmation switch. The controller controls the train to enter the "cleaning mode" according to other status information of the train, realizes fully automatic train activation, and automatically completes a series of necessary operations for the cleaning mode, such as turning on the interior lighting, air conditioning, and doors without occupying the driver's cab. After obtaining the trigger to exit the cleaning mode, the controller can automatically complete operations such as shutting down the train, so that the train "cleaning mode" does not require human operation throughout the process, and the purpose of full automation is achieved.

[0105] Below Figure 8 Taking the example, the implementation process of the cleaning mode control method provided in this embodiment is described again:

[0106] 1. The cleaning mode confirmation switch is activated and the train is activated;

[0107] 2. The controller detects whether the train's pantograph is in the landing position;

[0108] 3. If the pantograph is not in the landing position, the controller determines that the cleaning mode has not been entered and executes 25-29;

[0109] 4. If the pantograph is in the lowered position, the controller sends a pantograph raising command;

[0110] 5. The controller determines whether the pantograph is raised normally and whether the train is powered by the overhead line;

[0111] 6. If the pantograph is not raised normally, or the train does not receive power from the overhead line, the controller determines that the cleaning mode has not been entered and executes 25-29;

[0112] 7. If the pantograph is raised normally and the train is powered by the overhead line, the controller activates the train's lighting system;

[0113] 8. The controller detects whether the lighting system is turned on;

[0114] 9. If it is detected that the lighting system is not turned on, execute 22-29;

[0115] 10. If the lighting system is detected to be turned on, the controller sends a door enable activation signal on both sides; 11. The controller detects whether the door enable on both sides is activated normally (i.e., detects whether the door enable activation status signal sent by all door controllers is received);

[0116] 12. If the door enable on both sides is not activated normally (i.e., the door enable activation status signal sent by all door controllers is not received), execute 21-29;

[0117] 13. If the door enable on both sides is activated normally (i.e., the door enable activation status signal sent by all door controllers is received), the controller sends an opening command to the air conditioning system and sets the air conditioning mode to automatic mode;

[0118] 14. The controller detects whether the air conditioning system is working properly (i.e., whether the proportion of air conditioners that are turned on and in automatic mode is not less than the proportion threshold);

[0119] 15. If the air conditioning system does not work properly, the air conditioning fault status is sent to the ground control center, and the ground control center decides whether to continue cleaning or exit. If the ground center decides to continue cleaning, execute 16-29, and if the ground center decides to exit, execute 18-29; 16. If the air conditioning system works normally, the controller controls the display screen outside the train to display the information that the train is in a cleaning state;

[0120] 17. After obtaining a trigger for exiting the cleaning mode, the controller controls the train to exit the cleaning mode;

[0121] 18. The controller issues a command to cancel the door enable and a command to close the door;

[0122] 19. The controller determines whether all doors are closed;

[0123] 20. If there is a door that is not closed, execute 29; if all doors are closed, execute 21-29; 21. The controller issues a lighting off command;

[0124] 22. The controller issues a command to lower the bow;

[0125] 23. The controller determines whether the pantograph has landed normally;

[0126] 24. If the landing is normal, execute 25-29; if the landing is not normal, execute 29;

[0127] 25. The controller issues a train shutdown command;

[0128] 26. The controller confirms whether the train is powered off;

[0129] 27. If the power fails, the train is shut down;

[0130] 28. If the power is not cut off, it is considered that the train cannot automatically exit the cleaning mode, and go to 29;

[0131] 29. Maintain the current status of the train for maintenance personnel to handle.

[0132] Among them, one implementation scheme of step 17 is: 1) after the cleaning staff completes the cleaning of the vehicle, they pull out the cleaning mode key; 2) the controller obtains the trigger to exit the cleaning mode; 3) the controller cancels the door enable and issues a door closing command; 4) the controller determines whether all doors are closed; 5) if there are doors that are not closed, execute 29; if all doors are closed, control the air conditioner to force a warm mode command for 3 minutes, after 3 minutes the controller issues a lighting shutdown command, after 2 seconds the controller issues a pantograph lowering command, if the controller detects feedback on the pantograph lowering status, it issues a train shutdown command.

[0133] Another implementation of step 17 is: 1) When the cleaning staff completes the cleaning process of the train, the high voltage power supply of the train is lost; 2) The controller obtains the trigger to exit the cleaning mode; 3) The controller triggers the pre-recorded voice broadcast inside the train, such as the loss of high voltage, the vehicle will automatically shut down after 10 minutes. And after 10 minutes, the controller controls the train to exit the cleaning mode; 4) After 10 minutes, the controller cancels the door enable and issues a door closing command; 5) The controller determines whether all doors are closed; 6) If there are doors that are not closed, execute 29; if all doors are closed, the air conditioner is controlled to force a warm mode command for 3 minutes, and after 3 minutes, the controller issues a lighting shutdown command, and after 2 seconds, the controller issues a pantograph lowering command. If the controller detects the pantograph lowering status feedback, it issues a train shutdown command.

[0134] The present embodiment provides a cleaning mode control method, which is used to control the cleaning mode of a train; the outside of the train includes a cleaning mode confirmation switch, and the inside includes a controller; the method includes: if the cleaning mode confirmation switch is activated and the train is activated, then after the controller is powered on, the controller determines whether to enter the cleaning mode according to the pantograph state; if entering the cleaning mode, the controller activates the lighting system of the train, activates the door enable on both sides, and turns on the air conditioner; if a trigger to exit the cleaning mode is obtained, the controller controls the train to exit the cleaning mode. The method provided in this embodiment realizes automatic control of the cleaning mode of the train, and does not require cleaning personnel to participate in the control, avoiding the problem that the cleaning personnel forget to shut down the train, resulting in the train battery being depleted and unable to be activated normally.
