[0002] By adding an interface between the car wash machine and the track signal system, the linkage function between train control and car wash machine control can be realized. The existing linkage solutions are independent of each other and mainly fall into the following three categories: The first type is the car wash solution under manual control. This type of technical solution is to manually control the entire car wash process. The train stops at the specified location according to the dispatch of the commander, and the corresponding car wash machine is manually controlled to wash the car. Then the train drives out of the car wash garage according to manual dispatch.

[0003] The second and third categories are car wash solutions in FAO (Fully Automatic Operation) mode, which are full wash and side wash respectively. During the entire car wash process, the train automatically runs to the car wash request stop in front of the car wash garage. After the car wash is approved, the car wash arm falls down. In the full wash solution, the train needs to stop at the head wash position and the tail wash position respectively. In the side wash solution, the train passes through the car wash garage at a uniform speed throughout the journey to wash the entire car body. After washing, the car wash arm is retracted and the train automatically leaves the car wash garage.

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Figure 1 It is one of the flow diagrams of the train washing process provided by the present invention, such as Figure 1 As shown, the method may include the following steps: Step 110: receiving a first message sent by ATS (Automatic Train Supervision); the first message includes information of a first car wash mode; Step 120: Send a car wash request and a first message to a CI (Computer Interlocking); Step 130, receiving a car wash request approval message and a second message sent by the CI; the car wash request approval message is generated when it is determined that the car wash machine is in a normal state, and the second message is generated when it is determined that the car wash machine currently supports the first car wash mode; Step 140: performing a car wash operation based on the current target operation mode of the train and the first car wash mode; The first car wash mode is the car wash mode in the train operation plan or the car wash mode set by the ATS; The target operation mode includes any one of CM (Code Train Operation Mode), AM (Automatic Mode), and FAM (Fully Automatic Mode); The first car wash mode includes any one of full wash and side wash.

[0025] It should be noted that the above train washing method can be applied to trains. Specifically, the execution subject of the above train washing method can be a control unit of the train, such as VOBC (Vehicle On-Board Controller). The following description takes VOBC as an example.

[0026] Before step 110, a train operation plan may be prepared in advance, and the train washing time and washing mode (full wash or side wash) may be determined in the plan. After the train operation plan is determined, the ATS will save the train operation plan and trigger the VOBC and trackside equipment such as CI to wash the train when the train washing time arrives.

[0027] Furthermore, if the train washing time and / or mode needs to be temporarily modified after the train operation plan is determined, the dispatcher can reset the washing time and / or mode through the ATS.

[0028] In step 110, when the train's car wash time arrives, the ATS can periodically send a first message to the train's VOBC while allocating a car wash header code to the train. The first message includes information about the first car wash mode, which is the car wash mode in the train operation plan determined before step 110 or the car wash mode set by the ATS.

[0029] VOBC will periodically receive the first message sent by ATS.

[0030] In step 120, the VOBC will run to the car wash request parking spot in front of the car wash garage according to the calculated movement authorization, and will continue (at a certain period) to send the car wash request and the first message to the CI.

[0031] CI will correspondingly receive the car wash request and the first message sent by VOBC at a certain period, and will first determine the status of the car wash machine after receiving the car wash request and the first message each time.

[0032] If the car wash machine is in a normal state (i.e., it can perform car wash operations for the train), the CI will generate a car wash request pass message and determine the car wash mode currently supported by the car wash machine.

[0033] If the car washing machine currently supports the first car washing mode, the CI will generate a second message, where the second message is used to indicate that the car washing machine currently supports the first car washing mode.

[0034] After CI generates the car wash request approval message and the second message, CI sends the car wash request approval message and the second message to VOBC in step 130 .

[0035] When CI sends the second message, the car washing mode supported by the car washing machine can be indicated by high and low levels. For example, a high level can be used to indicate support for the full wash mode, and a low level can be used to indicate support for the side wash mode, and vice versa.

[0036] After receiving the car wash request approval message and the second message sent by CI, VOBC can determine that the car wash machine is currently in a normal state and that the car wash machine supports the first car wash mode.

[0037] Then, in step 140 , VOBC performs a car wash operation based on the current target operation mode of the train and the first car wash mode.

[0038] Specifically, the VOBC can control the onboard MMI (Man Machine Interface) to prompt the current first car wash mode (full wash or side wash), for example, by displaying it in text form in the 24-C area, and continue to display it until the train exits the car wash mode.

[0039] If the first car wash mode is side wash: When the target operation mode of the train is FAM mode: VOBC controls the train to run at a constant speed (for example, 3-5km / h) and stops at the turnaround section through the garage.

[0040] When the target operation mode of the train is AM mode: after VOBC meets the conditions for departure, VOBC controls the ATO (Automatic Train Operation) indicator to flash, and the train starts after the driver presses the ATO indicator. VOBC sends the car wash working conditions to the vehicle TCMS (Train Control and Management System), and controls the train to run at a constant speed (for example, 3-5km / h) through the car wash garage to the turnaround section and stop steadily. The turnaround button flashes to remind the driver to change ends.

[0041] When the target operation mode of the train is CM mode: after VOBC meets the conditions for departure, the train is manually driven to perform car washing. In CM mode, VOBC does not send the car washing status to the vehicle TCMS.

[0042] If the first car wash mode is full wash, the train needs to be controlled to stop accurately at the front wash position and the rear wash position. Specifically: When the target operation mode of the train is FAM mode: VOBC controls the train to stop precisely at the front wash position and the rear wash position.

[0043] When the target operation mode of the train is AM mode: VOBC controls the train to run to each parking point in the car wash process in sequence (front car wash parking point, rear car wash parking point, etc., with a stop indication (green window indication)), and executes the following process until the train passes through the car wash garage and stops steadily in the reversing section, and the reversing button flashes to remind the driver to change ends; When VOBC meets the departure conditions, the ATO indicator light flashes, the driver presses the ATO indicator light, and the train starts; ·VOBC controls the train to run at a constant speed (e.g. 3-5km / h) to the next stop.

[0044] When the target operation mode of the train is CM mode: after VOBC meets the conditions for departure, the train is manually driven to perform car washing. In CM mode, VOBC does not send the car washing status to the vehicle TCMS.

[0045] It can be understood that when the train runs to the turning stop point, after turning back and changing ends, VOBC no longer sends the car wash request and the first message to CI, and CI no longer replies to VOBC with the car wash request message and the second message.

[0046] The train washing method provided by the present invention realizes a double verification mechanism for car washing (whether the car can be washed and in which car washing mode the car can be washed) through the interaction between the train and the ATS and CI, which can ensure the smooth progress of the car washing. Under this double verification mechanism, the initially determined car washing mode can be determined by the train operation plan, or it can be temporarily set by the ATS, and the train can also wash the car in various operation modes. Therefore, the train washing method provided by the present invention can realize the train washing function in various situations and various train operation modes, thereby effectively improving the utilization rate of car washing resources and the efficiency of car washing.

[0047] In one embodiment, after step 120, the method may further include: receiving a car wash request passing message and a third message sent by the CI; the third message is generated when it is determined that the car wash machine currently does not support the first car wash mode but supports the second car wash mode, and the third message includes information about the second car wash mode; Sending a car wash mode change request to the ATS based on the third message; Receive the car wash mode change message sent by ATS, and perform car wash operations based on the current operating mode of the train and the second car wash mode.

[0048] If the car washing machine currently does not support the first car washing mode but supports the second car washing mode, the CI will generate a third message, and the third message is used to indicate that the car washing machine currently supports the second car washing mode.

[0049] Specifically, when the first car washing mode is side washing, and the car washing machine currently does not support side washing but supports full washing, the third message is used to indicate that the car washing machine currently supports full washing, and vice versa.

[0050] After CI generates the car wash request approval message and the third message, CI sends the car wash request approval message and the third message to VOBC.

[0051] After receiving the car wash request approval message and the third message sent by CI, VOBC can determine that the car wash machine is currently in a normal state, but the car wash machine currently supports the second car wash mode.

[0052] Then VOBC will send a car wash mode change request to ATS, and the car wash mode change request can feedback to ATS the alarm information of "the current car wash mode is inconsistent with the car wash mode set by ATS". Furthermore, the car wash mode change request can also specifically convey the information of "full wash mode setting failure" or "side wash mode setting failure".

[0053] After ATS receives the car wash mode change request sent by the train, it can pop up an alarm linkage prompt on the display interface (yard dispatch workstation, shift dispatch workstation, etc.): "Do you want to wash the car according to the current car wash machine working mode: full wash or side wash" and other prompts to remind the staff whether to change the train's car wash mode.

[0054] If the staff agrees to change the car wash mode and enters the corresponding instructions, ATS will respond to the input confirming the car wash mode change, generate a car wash mode change approval message and send it to VOBC.

[0055] After receiving the message that the car wash mode change is passed, VOBC will send the default value of the car wash mode command to CI (the default value means: it is invalid and neither full wash nor side wash), and control the train to perform car wash operations based on the current operating mode of the train and the second car wash mode.

[0056] When CI receives the default value of the car wash mode command sent by VOBC, it will instruct the car wash machine to operate according to the currently supported car wash mode until the car wash request sent by VOBC is invalid and CI returns to the internal default state.

[0057] The car washing method provided by the present invention can realize flexible change of the car washing mode by enabling the train, ATS, and CI to interact to allow the staff to determine whether to change the car washing mode when the car washing machine does not support the predetermined car washing mode, thereby realizing the train car washing function in various situations and further improving the utilization rate of car washing resources and car washing efficiency.

[0058] In one embodiment, after sending the car wash request and the first message to the CI, the method further includes: Receive the car wash exception message sent by CI; the car wash exception message is generated when it is determined that the car wash machine is in an abnormal state or a busy state.

[0059] If CI determines that the car wash machine is in an abnormal state (a state in which it cannot operate normally) or a busy state (although it operates normally, it is temporarily used by other trains and cannot provide car wash services), CI will generate a car wash exception message and send it to VOBC to indicate that the car wash cannot be performed at present.

[0060] After receiving the car wash abnormality message, VOBC can control the onboard MMI to prompt the car wash abnormality so that the driver or staff can end the car wash process.

[0061] The car washing method provided by the present invention can avoid waste of resources and potential safety hazards by promptly prompting the train when the car washing machine cannot provide car washing service.

[0062] Figure 2 This is the second flow diagram of the train washing process provided by the present invention, such as Figure 2 As shown, the method may include the following steps: Step 210: The ATS sends a first message to the train; the first message includes information about the first car wash mode; Step 220: CI receives the car wash request and the first message sent by the train; Step 230: if the CI determines that the car wash machine is in a normal state, a car wash request approval message is generated based on the car wash request; if the CI determines that the car wash machine supports the first car wash mode, a second message is generated; Step 240: The CI sends a request-to-pass message and a second message to the train. The first car wash mode is the car wash mode in the train operation plan or the car wash mode set by the ATS; The first car wash mode includes any one of full wash and side wash.

[0063] It should be noted that the above train washing method can be applied to trackside equipment. Specifically, the execution body of the above train washing method can be ATS and CI.

[0064] Before step 210, a train operation plan may be prepared in advance, and the train washing time and washing mode (full wash or side wash) may be determined in the plan. After the train operation plan is determined, the ATS will save the train operation plan and trigger the VOBC and trackside equipment such as CI to wash the train when the train washing time arrives.

[0065] Furthermore, if the train washing time and / or mode needs to be temporarily modified after the train operation plan is determined, the dispatcher can reset the washing time and / or mode through the ATS.

[0066] In step 210, when the train's car wash time arrives, the ATS can periodically send a first message to the train's VOBC while allocating a car wash header code to the train. The first message includes information about the first car wash mode, which is the car wash mode in the train operation plan determined before step 110 or the car wash mode set by the ATS.

[0067] VOBC will periodically receive the first message sent by ATS.

[0068] In step 220, the VOBC will run to the car wash request parking spot in front of the car wash garage according to the calculated movement authorization, and will continue (at a certain period) to send the car wash request and the first message to the CI.

[0069] CI will correspondingly receive the car wash request and the first message sent by VOBC at a certain period.

[0070] In step 230 , after receiving each car wash request and the first message, the CI first determines the status of the car wash machine.

[0071] If the car wash machine is in a normal state (i.e., it can perform car wash operations for the train), the CI will generate a car wash request pass message and determine the car wash mode currently supported by the car wash machine.

[0072] If the car washing machine currently supports the first car washing mode, the CI will generate a second message, where the second message is used to indicate that the car washing machine currently supports the first car washing mode.

[0073] After CI generates the car wash request approval message and the second message, CI sends the car wash request approval message and the second message to VOBC in step 240 .

[0074] When CI sends the second message, the car washing mode supported by the car washing machine can be indicated by high and low levels. For example, a high level can be used to indicate support for the full wash mode, and a low level can be used to indicate support for the side wash mode, and vice versa.

[0075] After receiving the car wash request approval message and the second message sent by CI, VOBC can determine that the car wash machine is currently in a normal state and that the car wash machine supports the first car wash mode.

[0076] The train washing method provided by the present invention realizes a double verification mechanism for car washing (whether the car can be washed and in which car washing mode the car can be washed) through the interaction between the train and the ATS and CI, which can ensure the smooth progress of the car washing. Under this double verification mechanism, the initially determined car washing mode can be determined by the train operation plan, or it can be temporarily set by the ATS, and the train can also wash the car in various operation modes. Therefore, the train washing method provided by the present invention can realize the train washing function in various situations and various train operation modes, thereby effectively improving the utilization rate of car washing resources and the efficiency of car washing.

[0077] In one embodiment, after step 220, the method may further include: When the CI determines that the car washing machine does not support the first car washing mode but supports the second car washing mode, a third message is generated; the third message includes information of the second car washing mode; The CI sends a request-to-pass message and a third message to the train; The ATS receives a car wash mode change request sent by the train; the car wash mode change request is generated based on the third message; The ATS sends a car wash mode change approval message to the train in response to the input confirming the car wash mode change.

[0078] If the car washing machine currently does not support the first car washing mode but supports the second car washing mode, the CI will generate a third message, and the third message is used to indicate that the car washing machine currently supports the second car washing mode.

[0079] Specifically, when the first car washing mode is side washing, and the car washing machine currently does not support side washing but supports full washing, the third message is used to indicate that the car washing machine currently supports full washing, and vice versa.

[0080] After CI generates the car wash request approval message and the third message, CI sends the car wash request approval message and the third message to VOBC.

[0081] After receiving the car wash request approval message and the third message sent by CI, VOBC can determine that the car wash machine is currently in a normal state, but the car wash machine currently supports the second car wash mode.

[0082] Then VOBC will send a car wash mode change request to ATS, and the car wash mode change request can feedback to ATS the alarm information of "the current car wash mode is inconsistent with the car wash mode set by ATS". Furthermore, the car wash mode change request can also specifically convey the information of "full wash mode setting failure" or "side wash mode setting failure".

[0083] After ATS receives the car wash mode change request sent by the train, it can pop up an alarm linkage prompt on the display interface (yard dispatch workstation, shift dispatch workstation, etc.): "Do you want to wash the car according to the current car wash machine working mode: full wash or side wash" and other prompts to remind the staff whether to change the train's car wash mode.

[0084] If the staff agrees to change the car wash mode and inputs the corresponding instructions, the ATS will respond to the input confirming the change of the car wash mode, generate a car wash mode change approval message and send it to the VOBC.

[0085] After receiving the message that the car wash mode change is passed, VOBC will send the default value of the car wash mode command to CI (the default value means: it is invalid and neither full wash nor side wash), and control the train to perform car wash operations based on the current operating mode of the train and the second car wash mode.

[0086] When CI receives the default value of the car wash mode command sent by VOBC, it will instruct the car wash machine to operate according to the currently supported car wash mode until the car wash request sent by VOBC is invalid and CI returns to the internal default state.

[0087] The car washing method provided by the present invention can realize flexible change of the car washing mode by enabling the train, ATS, and CI to interact to allow the staff to determine whether to change the car washing mode when the car washing machine does not support the predetermined car washing mode, thereby realizing the train car washing function in various situations and further improving the utilization rate of car washing resources and car washing efficiency.

[0088] In one embodiment, after the CI receives the car wash request and the first message sent by the train, the method further includes: When it is confirmed that the car wash machine is in an abnormal state or busy state, a car wash abnormality message is generated and sent to the train.

[0089] If CI determines that the car wash machine is in an abnormal state (a state in which it cannot operate normally) or a busy state (although it operates normally, it is temporarily used by other trains and cannot provide car wash services), CI will generate a car wash exception message and send it to VOBC to indicate that the car wash cannot be performed at present.

[0090] After receiving the car wash abnormality message, VOBC can control the onboard MMI to prompt the car wash abnormality so that the driver or staff can end the car wash process.

[0091] The car washing method provided by the present invention can avoid waste of resources and potential safety hazards by promptly prompting the train when the car washing machine cannot provide car washing service.

[0092] In an example of a specific application of the train washing method provided by the present invention, the following aspects are also included: Prerequisites for train washing: The prerequisite for the car washing machine to start automatic car washing is that the car washing machine is in automatic mode. The train applies for a "car washing request" and the car washing machine replies "agree to wash the car". The car washing machine will start automatic car washing. Otherwise, the car washing machine will not start the automatic car washing process. 1. When the train is in RM (Restricted Manual) mode, for example, if the manually driven train enters the car wash garage and is upgraded to FAM mode, AM mode or CM mode, the car wash machine will not automatically start washing the car.

[0093] 2. After the car wash is completed, the car wash machine will not automatically start washing the car when the train turns back and passes through the wash garage in the opposite direction.

[0094] 3. In RM mode, the car washing machine should be in manual mode and operated according to the car washing line interface. The car washing machine should not automatically identify the train and start washing automatically.

[0095] By setting the above-mentioned prerequisites for washing the train, it is possible to ensure that the train washing method of the present invention is carried out safely.

[0096] Furthermore, for the interface between CI and the car washing machine, the design shown in Table 1 is adaptively adopted: Table 1CI-Car Washing Machine Interface Description Information Table

[0097] For the interface between the car wash machine and CI, the design shown in Table 2 is adaptively adopted: Table 2 Car Washer-CI Interface Description Information Table

[0098] For the abnormalities that occur during the implementation of the train washing method of the present invention, the following solutions are adopted: 1. When the scheduled train to be washed is not at the specified location or the car washing machine is not ready, ATS will not prompt the car washing plan, but will send an alarm to the yard dispatch and dispatch workstation (pop-up prompt: subject to the control area).

[0099] 2. During the car wash process, if the car wash mode replied by CI is invalid or the car wash mode changes, VOBC applies emergency braking and exits the car wash condition. If it does not enter the car wash condition at this time, it will not enter the car wash condition, and alarm ATS will be alerted. VOBC will no longer send a car wash request to CI. After the train stops, VOBC sends a pass request to CI. After the car wash machine confirms that the car wash arm of the car wash machine is retracted to meet the conditions for passing the car wash machine, the car wash machine automatically gives a message of permission to pass. After receiving the message of permission to pass, CI forwards it to VOBC. After receiving the message of permission to pass replied by CI, VOBC controls the train to run to the reversing track and stop according to the driving mode.

[0100] 3. During the fully automatic car wash process, if the car wash machine fails or the emergency stop button is pressed manually, the car wash machine needs to send an emergency stop command to CI and cancel the "agree to car wash" command. CI forwards the emergency stop command to VOBC, VOBC implements emergency braking, and after VOBC checks the zero speed of the train, it prompts the driver to turn on the key and switch to manual driving.

[0101] 4. The response range of the emergency stop button: from the time the train stops in front of the garage and enters the car wash condition to the time the rear of the train leaves the car wash garage.

[0102] 5. The car washing machine cannot start washing before detecting that the train has stopped correctly.

[0103] 6. During the car wash process, if the vehicle, signal or other faults cause the train to brake urgently, VOBC should immediately alarm the dispatching / vehicle expert workstation and stop the car wash, exit the car wash condition, and cancel the car wash application. The car wash machine should cancel its consent to wash the car, terminate the car wash and retract the car wash arm.

[0104] 7. If the site dispatcher fails to confirm the car wash task within the prompt time (2 minutes, configurable), the car wash operation will no longer be automatically triggered.

[0105] 8. If the car wash route fails to be triggered after the site dispatcher confirms the car wash, an alarm will be sent to the line dispatcher and the car wash route will no longer be triggered.

[0106] 9. If a fire occurs in a train during the fully automatic car wash process, VOBC controls the train to stop immediately (normal braking) and stop sending car wash requests, exit the car wash condition, send a pass request to the car wash machine, and after receiving a pass reply: If it is a dead-end car wash station, the VOBC controls the train to run in FAM mode and stop at the turnaround stop; If it is a through-type car wash station, the VOBC controls the train to run forward in FAM mode to the designated exit car wash position and stop.

[0107] If a bow-changing parking point is set up in the car wash garage, it is necessary to stop at the bow-changing parking point and change the bow before continuing to operate.

[0108] 10. When the car wash operation is terminated due to some reasons, the fault will be handled remotely / manually.

[0109] 11. After the fault is handled, the car washer can automatically / manually confirm and send a pass signal to VOBC, and VOBC controls the train to run to the specified position.

[0110] 12. ATS automatically triggers the return route to the designated train inspection warehouse according to the car wash plan. If the designated train inspection warehouse is occupied, an alarm will be sent to the central ATS and it will not be automatically triggered.

[0111] 13. Other matters: CI controls the entire garage to allow only one train.

[0112] CI continuously sends "car wash request" as a condition for enabling the car wash machine. Enabling the car wash machine means that the car wash machine will lower the car wash arm and wash the car body only when it continuously receives this signal. Otherwise, it should stop washing the car immediately.

[0113] After the train interrupts the car wash, the onboard signal system sends a pass request to the car wash machine. After the car wash equipment returns to the limit, the car wash machine no longer monitors whether the car wash request continues based on this signal.

[0114] When the train is washed in RM mode, the following process can be followed: 1. When a train is washing in RM mode, the duty officer in the vehicle base signal tower contacts the duty officer in the car wash machine control room by phone to request downgrade of car washing.

[0115] 2. After receiving a phone call from the signal tower attendant, the attendant in the car wash control room confirms that the car wash garage is free and has the conditions for car washing, and then presses the downgrade car wash consent button (JJXTA). After the vehicle base CI confirms that the downgrade car wash consent button has been pressed, it sends the "downgrade car wash consent light" lighting information to the ATS system through the existing interface. The "downgrade car wash consent light" on the ATS system local interface lights up green, and at the same time, the CI drives the relay on the car wash console to light up, triggering the "downgrade car wash consent light" to light up.

[0116] 3. The duty officer of the vehicle base signal tower handles the shunting route from S1B to Z1. When the S1B-1BG shunting route is locked, the CI driver lights up the downgraded car wash indicator light on the car wash machine console.

[0117] 4. When the S1B-1BG access route is unlocked, the car wash machine attendant must pull out the downgrade car wash consent button after the downgrade car wash process indicator light goes out. The downgrade car wash consent light on the car wash machine console goes out, indicating that the car wash is over.

[0118] 5. After the car wash attendant pulls out the downgrade car wash consent button, he presses the downgrade mode consent button (JJXTGA, non-self-resetting), and CI sends the "downgrade mode consent light" lighting information to the ATS system through the interface. The ATS system lights up the "downgrade mode consent light" on the local interface, and the vehicle base signal tower attendant handles the passing route at the local workstation, and the train passes through the car wash. If the downgrade mode consent button is not pressed, the starting signal cannot be opened.

[0119] 6. When the train leaves the car wash garage, pull out the downgrade mode and press the button to pass the car wash garage, and the downgrade car wash is completed.

[0120] When the train is washing in RM mode, the interface circuit is designed as follows: The car wash machine control room presses the downgrade car wash consent button (JJXTA), and the vehicle base execution unit scattered input board collects the downgrade car wash consent button pressing status, and CI lights up the "downgrade car wash consent indication light" on the car wash machine control panel, which also serves as the inspection condition for the opening of the S1B signal shunting signal. When passing through the car wash garage in the reverse direction, the car wash machine control room presses the downgrade car wash consent pass button (JJXTGA), and the vehicle base execution unit scattered input board collects the downgrade car wash consent pass button pressing status, and CI lights up the "downgrade car wash consent pass indication light" on the car wash machine control panel, which also serves as the inspection condition for the opening of the X1A signal shunting signal.

[0121] Downgrade car wash consent light: Normally, the red light is on (indicating that the car wash machine refuses to downgrade the car wash). The green light is on after the vehicle base CI collects the status of the downgrade car wash consent button being pressed (indicating that the car wash machine agrees to downgrade the car wash).

[0122] Downgraded car wash consent light: Normally the light is off (indicating that passing through the garage is not allowed). When the downgraded car wash consent button is pressed, the yellow light is on (indicating that passing through the garage is allowed).

[0123] When the car washing machine agrees to downgrade the car washing, the car washing machine attendant presses the downgrade car washing approval button.

[0124] After the vehicle base CI collects the pressing status of the downgrade car wash consent button, the downgrade car wash consent light on the car wash machine console lights up green.

[0125] When the S1B-1BG shunting approach to the vehicle base is locked, the downgraded car wash indicator light turns white.

[0126] When the train is washing in RM mode, the abnormal handling and precautions are as follows: 1. The car wash system is not started based on the car wash request from the signal system, but is started based on the request of the driver or local operator.

[0127] 2. When the downgrade car wash consent procedures have been completed but the car wash access conditions have not been processed, in order to change the car wash plan at this time, the operator on duty in the car wash control room needs to pull out the downgrade car wash consent button on the car wash console to turn off the "downgrade car wash consent light" on the car wash console and on the vehicle base, and cancel the downgrade car wash consent procedures.

[0128] 3. If the car wash access has been processed, the vehicle base attendant needs to cancel the car wash access first. When the downgrade car wash indicator light on the car wash machine console goes out, the attendant in the car wash machine control room pulls out the downgrade car wash consent button on the car wash machine console to turn off the "downgrade car wash consent light" on the car wash machine console and the vehicle base, thus canceling the downgrade car wash consent procedure.
