[0018] When neither the internal sensor switch nor the external sensor switch of the door is triggered for a predetermined cumulative time, controlling the door to close automatically;

[0019] Determine whether the door is fully closed. If so, update the display status of the external display panel to the unoccupied state, continue to process the sensing signal of the internal sensing switch, and display the unlocked state through the internal sensing switch display on the inside of the door.

[0020] In an exemplary embodiment, the method further includes:

[0021] After determining that the door is fully closed, controlling the door to open when detecting that an external sensor switch of the door is triggered;

[0022] After the door is opened, it is determined whether the internal sensor switch of the door is triggered. If triggered, the door is controlled to close, and the locked state is displayed on the internal sensor switch display, and the display state of the external display panel is updated to the occupied state. If not triggered, the door is controlled to close after a first preset time delay, and the sensing signal of the internal sensor switch is continuously processed during the delayed closing process, and the unlocked state is displayed on the internal sensor switch display.

[0023] Determine whether the internal sensor switch is triggered again. If so, control the door to open, display the unlocked state through the internal sensor switch display, and update the display state of the external display panel to the unoccupied state.

[0024] In an exemplary embodiment, the method further includes:

[0025] When it is detected that there is someone in the bathroom, the bathroom ceiling light and the mirror light are controlled to light up at a first brightness;

[0026] When it is detected that no one is in the bathroom for a second preset time period, the bathroom ceiling light and the mirror light are controlled to light up at a second brightness; the first brightness is greater than the second brightness.

[0027] In an exemplary embodiment, the method further includes:

[0028] The air imaging interactive screen is displayed to the user through the air imaging system so that the user can operate the corresponding sanitary equipment through the air imaging interactive screen.

[0032] In an exemplary embodiment, the interior sensing switch includes a first recessed portion provided on an inner door panel of the toilet, wherein a first infrared sensor is disposed in the first recessed portion; the interior sensing switch includes a second recessed portion provided on an outer door panel of the toilet, wherein a second infrared sensor is disposed in the second recessed portion; and the method further includes:

[0033] determining whether the internal sensing switch is triggered according to the detection signal of the first infrared sensor;

[0034] Determine whether the external sensing switch is triggered according to the detection signal of the second infrared sensor.

[0035] Another aspect of the present invention provides a rail vehicle restroom, comprising: a housing, a door disposed on the housing, an internal sensing switch disposed on the inner side of the door, an external sensing switch disposed on the outer side of the door, an external display panel, sanitary equipment disposed inside the housing, a toilet, a memory, and a processor, wherein the processor is connected to the internal sensing switch, the external sensing switch, and the external display panel, wherein:

[0036] memory for storing computer programs;

[0037] The processor is configured to implement the steps of the above-mentioned method for controlling a rail vehicle toilet when executing the computer program.

[0038] It can be seen from the above technical solutions that the embodiments of the present invention have the following advantages:

[0039] A control method for a rail vehicle toilet is provided in an embodiment of the present invention, the method comprising: detecting whether the waste tank is full by means of a position sensor provided on the waste tank in the toilet; if so, updating the display status of an external display panel to a maintenance status; if not, obtaining trigger information of the last door closing action; when it is determined according to the trigger information that the last door closing action was triggered by an internal sensing switch, updating the display status of the external display panel to a occupied status; when it is determined according to the trigger information that the last door closing action was triggered by an external sensing switch or was automatically closed, updating the display status of the external display panel to an unoccupied status.

[0040] It can be seen that in the embodiment of the present invention, the status of the waste tank can be detected by a position sensor set on the waste tank in the toilet. When the waste tank is full, it means that the toilet cannot be used normally. At this time, the maintenance status can be directly displayed through the external display panel. When the waste tank is not full, if the last door closing action was triggered by the internal sensing switch, it means that there is someone in the toilet. At this time, the external display panel displays the status of someone. If the last door closing action was triggered by the external sensing switch or the door was closed automatically, it means that there is no one inside. At this time, the external display panel displays the status of no one. The various states displayed by the external display panel can enable external passengers to accurately understand the usage status of the toilet, which is conducive to improving the passenger experience.

[0041] In addition, the present invention also provides a rail vehicle toilet control method, which has corresponding advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The embodiment of the present invention provides a rail vehicle toilet and a control method thereof, which can enable external passengers to accurately understand the usage status of the toilet during use, thereby improving the passenger experience.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 making creative efforts shall fall within the scope of protection of the present invention.

[0053] Please refer to Figure 1 , Figure 1 A flow chart of a method for controlling a rail vehicle toilet provided by an embodiment of the present invention. The method for controlling a rail vehicle toilet is applied to a rail vehicle toilet, and the method includes:

[0054] S110: Detect whether the waste box is full by using a position sensor provided on the waste box in the toilet; if so, proceed to S120; if not, proceed to S130;

[0055] It should be noted that in an embodiment of the present invention, a position sensor can be set at a preset position on the toilet waste tank (such as a preset distance from the upper cover of the waste tank). Specifically, a liquid level sensor can be set to detect the position of the waste in the waste tank through the liquid level sensor. Based on the position, it can be determined whether the waste tank is full.

[0056] S120: updating the display state of the external display panel to a maintenance state;

[0057] Specifically, if the waste tank is full, indicating that the restroom is unavailable, the external display panel will display a "maintenance" status, allowing passengers outside to understand the restroom's actual condition. A maintenance status indicates that the restroom is temporarily unavailable and requires maintenance. Furthermore, staff can use the "maintenance" status displayed on the external display panel to promptly clean the waste tank, allowing the restroom to be put back into normal use as soon as possible.

[0058] In addition, in order to avoid equipment failure caused by passengers continuing to use the toilet, the toilet door can be controlled to close automatically when it is detected that the waste tank is full.

[0059] S130: Obtain trigger information of the last door closing action;

[0060] Specifically, when it is determined that the waste box is not full, the trigger information of the last door closing action can be further obtained, and the triggering person of the last door closing action can be determined according to the trigger information, for example, the internal sensor switch or the external sensor switch.

[0061] S140: When it is determined according to the trigger information that the last door closing action was triggered by the internal sensor switch, the display status of the external display panel is updated to the occupied state;

[0062] Specifically, when it is determined based on the trigger information that the last door closing action was triggered by an internal sensing switch, it can be determined that someone has entered the bathroom and locked the door from the inside. At this time, the display status of the external display panel can be updated to a occupied status, that is, the external display panel displays "someone is present".

[0063] S150: When it is determined according to the trigger information that the last door closing action was triggered by an external sensor switch or automatically closed, the display status of the external display panel is updated to an unmanned state.

[0064] Specifically, when it is determined based on the trigger information that the last door closing action was triggered by an external sensor switch or was automatically closed, it can be determined that someone came out of the bathroom and closed the bathroom door or no one entered the bathroom for a long time and the bathroom door closed automatically. At this time, the display status of the external display panel can be updated to an unmanned status, that is, the external display panel displays "unmanned".

[0065] Furthermore, when it is determined according to the trigger information that the last door closing action was triggered by the internal sensor switch, the method may further include:

[0066] Stop processing the sensing signal of the external sensing switch to control the external sensing switch to fail;

[0067] When it is determined based on the trigger information that the last door closing action was triggered by an external sensor switch or automatically closed, it also includes:

[0068] The sensing signal of the external sensing switch is continuously processed to control the external sensing switch to take effect, and the bathroom door is controlled to open when the external sensing switch detects door opening information.

[0069] It should be noted that, in the embodiment of the present invention, it is determined based on the trigger information that the last door closing action was triggered by the internal sensing switch, indicating that there is someone in the bathroom. At this time, the external sensing switch can be controlled to be invalid. Specifically, the external sensing switch can be controlled to be invalid by stopping processing the sensing signal of the external sensing switch. When the external sensing switch fails, people outside the bathroom will not be able to open the bathroom door through the external sensing switch, thereby ensuring the safety of people inside the bathroom.

[0070] In addition, when it is determined according to the trigger information that the last door closing action was triggered by an external sensor switch or automatically closed, it means that there is no one in the bathroom and the external sensor switch can be controlled to take effect. Specifically, the external sensor switch can be controlled to take effect by continuing to process the sensing signal of the external sensor switch, so that external passengers can open the bathroom door by sensing the external sensor switch. Specifically, when the door opening information detected by the external sensor switch is obtained, the bathroom door can be controlled to open so that external passengers can enter the bathroom.

[0071] Furthermore, after updating the display state of the external display panel to the maintenance state, the following steps may also be included:

[0072] When someone is detected in the bathroom, a first alarm is issued;

[0073] And / or, when it is detected that the bathroom door loses power, a second alarm prompt is issued.

[0074] It should be noted that after detecting that the waste tank is full and updating the display status of the external display panel to the maintenance status, the toilet door can be controlled to close automatically. If someone is still detected in the toilet, the passenger cannot open the toilet door automatically. At this time, a first alarm prompt can be issued. Specifically, the first alarm prompt can be issued after the passenger inside the toilet triggers the alarm device, so that after receiving the first alarm prompt, the external staff can turn on the emergency unlocking switch outside the toilet and unlock it through the four corner locks, thereby helping the passengers in the toilet to open the toilet door.

[0075] In addition, if the toilet door is detected to have lost power, a second alarm can be issued regardless of whether there are passengers in the toilet, so that the staff can open the emergency unlocking switch outside the toilet and unlock it through the four corner locks after receiving the alarm, thereby opening the toilet door.

[0076] Furthermore, the method may further include:

[0077] When neither the internal nor the external sensor switches of the door are triggered for a preset cumulative time, the door will be automatically closed.

[0078] Determine whether the door is fully closed. If so, update the display status of the external display panel to the unoccupied state, continue to process the sensing signal of the internal sensing switch, and display the unlocked state on the inside of the door through the internal sensing switch display.

[0079] It should be noted that in embodiments of the present invention, if it is detected that neither the internal sensor switch nor the external sensor switch of the door has been triggered for a preset cumulative time period, it can be indicated that no one is using the restroom. At this time, the door can be controlled to automatically close, and when the door is fully closed, "No One" will be displayed on the external display panel. To facilitate the next passenger entering the restroom to lock the door using the internal sensor switch, the sensing signal of the internal sensor switch can continue to be processed, and the unlocked status can be displayed on the inner side of the door through the internal sensor switch display. The user can more intuitively understand that the internal sensor switch is usable through the unlocked status displayed on the internal sensor switch display, thereby improving the user experience.

[0080] Furthermore, the method may further include:

[0081] After determining that the door is fully closed, the door is controlled to open when the external sensor switch of the door is detected to be triggered;

[0082] After the door is opened, it is determined whether the internal sensor switch of the door is triggered. If it is triggered, the door is controlled to close, the processing of the sensing signal of the internal sensor switch is stopped, and the locked state is displayed on the internal sensor switch display, and the display state of the external display panel is updated to the occupied state. If it is not triggered, the door is controlled to close after a first preset time delay, and the sensing signal of the internal sensor switch is continued to be processed during the delayed closing process, and the unlocked state is displayed on the internal sensor switch display;

[0083] Determine whether the internal sensor switch is triggered again. If so, continue to process the sensing signal of the internal sensor switch, control the door to open, display the unlocked state through the internal sensor switch display, and update the display state of the external display panel to the unmanned state.

[0084] It should be noted that, in the embodiment of the present invention, when the time period during which neither the internal sensing switch nor the external sensing switch of the door has been triggered reaches a preset cumulative time period, the door is controlled to close automatically. After the door is fully closed, if the external sensing switch of the door is detected to be triggered, it indicates that a passenger needs to enter the restroom, and at this time, the door can be controlled to open. Furthermore, after the door is opened, if the internal sensing switch is triggered, it indicates that a passenger has entered the restroom and needs to close the door. At this time, the restroom door can be controlled to close, and the locked state can be displayed through the internal sensing switch display, so that the passengers inside the restroom can intuitively understand the state of the internal sensing switch, and the display state of the external display panel can be updated to the occupied state. In addition, the processing of the sensing signal of the external sensing switch can be stopped to control the external sensing switch to fail, and prevent external passengers from opening the door through the external sensing switch.

[0085] After the door is opened, if the internal sensor switch is not triggered, the door can be controlled to close after a first preset time delay to prevent someone from entering the bathroom within the first preset time. During the delayed closing process of the door, the sensing signal of the internal sensor switch can continue to be processed so that the user's door closing demand can be detected in time after someone enters the bathroom. During this process, the unlocking status can be displayed through the internal sensor switch display so that someone can intuitively understand the current status of the internal sensor switch after entering the bathroom.

[0086] If a passenger enters the restroom and closes the door by operating the internal sensor switch for the first time, the system will display the locked status through the internal sensor switch display. If the internal sensor switch is detected to be triggered again, it means that the passenger in the restroom needs to leave the restroom. At this time, the door can be controlled to open, and the unlocked status can be displayed through the internal sensor switch display. The display status of the external display panel is updated to the unoccupied status so that external passengers can understand the restroom status in a timely manner.

[0087] Furthermore, the method may further include:

[0088] When someone is detected in the bathroom, the bathroom ceiling light and the mirror light are controlled to light up at the first brightness;

[0089] When it is detected that there is no one in the bathroom for a second preset time period, the bathroom ceiling light and the mirror light are controlled to light up at a second brightness; the first brightness is greater than the second brightness.

[0090] It should be noted that if Figure 2As shown, in order to better realize the contactless use of the bathroom in the embodiment of the present invention, an infrared sensor can be set on the bathroom ceiling. When the infrared sensor detects that there is someone in the bathroom, the bathroom ceiling lighting and the mirror light can be controlled to light up according to the first brightness. Specifically, when the infrared sensor detects that there is someone, a high-level signal can be output to the bathroom ceiling lighting and the mirror light to make the bathroom ceiling lighting and the mirror light output full power and all lights are on. When the infrared sensor detects that there is no one in the bathroom and the length of time when no one is there reaches a second preset length of time (such as 15s), the bathroom ceiling lighting and the mirror light can be controlled to light up according to the second brightness. Specifically, a low level can be output to the bathroom ceiling lighting and the mirror light, and the lamp power is reduced to 30% of the original, and the light becomes dim, thereby realizing contactless lighting energy-saving control of the bathroom.

[0091] Furthermore, the method may further include:

[0092] The air imaging system displays an air imaging interactive screen to the user so that the user can operate the corresponding sanitary equipment through the air imaging interactive screen.

[0093] Specifically, the inductive sanitary facilities in the rail vehicle toilet in the embodiment of the present invention may include inductive water valves, inductive toilets, inductive large paper rolls, inductive flushing buttons and other facilities. Figure 3 As shown, in order to further realize contactless operation, the operation buttons can be projected into the air through the air imaging interactive screen, and the passengers operate the imaging buttons to operate the target sensing sanitary facilities.

[0094] It should also be noted that there are induction water valves in the rail vehicle toilets, taking into account the anti-freezing measures for rail vehicles in winter, such as Figure 4 As shown, in this application, a zero-pressure differential solenoid valve (specifically, a zero-pressure differential DC24V solenoid valve) can be set in the drainage pipeline. Since the zero-pressure differential solenoid valve does not require the external water pressure to reach a preset value, even if the water pressure is zero, water will be supplied as long as there is water. Therefore, the setting of the zero-pressure differential solenoid valve can open when there is water in the drainage management, thereby draining the water in the drainage pipeline to prevent freezing. Specifically, when the vehicle needs to be emptied for antifreeze, the vehicle executes the antifreeze emptying command to empty the water inside the water valve to prevent freezing.

[0095] Furthermore, the method may further include:

[0096] When a toilet seat ring drop instruction is detected, the seat ring is controlled to fall, and after the seat ring is fitted with the toilet seat, the seat cushion cover on the toilet seat is replaced;

[0097] When it is detected that the flush button of the toilet is triggered, the seat cushion is controlled to flip up and then the toilet is controlled to perform a flushing action.

[0098] It should be noted that the toilet in the embodiment of the present invention is an induction toilet, which has the functions of automatically flipping over the seat gasket and automatically changing the seat cushion cover. Considering that the toilets in rail vehicles are used frequently, when the toilet in the toilet of a rail vehicle is not in use, the seat gasket is set to a flipped-up state. When a passenger needs to sit on the toilet, the seat gasket is triggered to fall. After the seat gasket falls and fits with the toilet, the seat cushion cover is automatically replaced simultaneously. After the toilet is used, the passenger triggers the toilet flush button. When it is detected that the toilet flush button is triggered, the seat gasket flips up and the toilet is controlled to complete the flushing action. This can reduce the failure rate caused by the frequent rising and falling of the seat gasket to a certain extent, and when a passenger needs to sit on the toilet, the toilet seat is controlled to fall and the seat cushion cover is replaced at the same time, which can further ensure hygiene and safety and improve the passenger experience.

[0099] Furthermore, the interior sensing switch includes a first recessed portion provided on the inner door panel of the toilet, wherein a first infrared sensor is provided in the first recessed portion; the interior sensing switch includes a second recessed portion provided on the outer door panel of the toilet, wherein a second infrared sensor is provided in the second recessed portion; and the method further includes:

[0100] determining whether the internal sensing switch is triggered according to the detection signal of the first infrared sensor;

[0101] Determine whether the external sensing switch is triggered according to the detection signal of the second infrared sensor.

[0102] It should be noted that in order to prevent the traditional external infrared sensor device from mistakenly identifying passers-by as toilet users, such as Figure 5 As shown, in an embodiment of the present invention, a first recessed portion is provided on the inner door panel of the toilet, and a second recessed portion is provided on the outer door panel. The first infrared sensor is provided in the first recessed portion, and the second infrared sensor is provided in the second recessed portion. A display panel corresponding to the internal sensing switch and a display panel corresponding to the external sensing switch can also be provided. The passenger needs to put his finger into the recess to activate the sensing switch, thereby achieving contactless door opening while avoiding false triggering.

[0103] It can be seen that in the embodiment of the present invention, the status of the waste tank can be detected by a position sensor set on the waste tank in the toilet. When the waste tank is full, it means that the toilet cannot be used normally. At this time, the maintenance status can be directly displayed through the external display panel. When the waste tank is not full, if the last door closing action was triggered by the internal sensing switch, it means that there is someone in the toilet. At this time, the external display panel displays the status of someone. If the last door closing action was triggered by the external sensing switch or the door was closed automatically, it means that there is no one inside. At this time, the external display panel displays the status of no one. The various states displayed by the external display panel can enable external passengers to accurately understand the usage status of the toilet, which is conducive to improving the passenger experience.

[0104] Based on the above embodiment, another aspect of the present invention provides a rail vehicle toilet, comprising: a housing, a door provided on the housing, an internal sensing switch provided on the inner side of the door, an external sensing switch provided on the outer side of the door, an external display panel, sanitary equipment provided inside the housing, a toilet, a memory, and a processor, wherein the processor is connected to the internal sensing switch, the external sensing switch, and the external display panel, wherein:

[0105] memory for storing computer programs;

[0106] The processor is used to implement the steps of the above-mentioned rail vehicle toilet control method when executing the computer program.

[0107] It should also be noted that if Figure 6 As shown, the rail vehicle toilet in the embodiment of the present invention includes main structures such as an intelligent toilet door 1, an induction paper box 2, an intelligent toilet 3, an induction flush button 4, and an induction water valve 5. The toilet shell can use a glass fiber aramid paper honeycomb board instead of a fiberglass + aluminum frame, such as Figure 7 As shown, the toilet shell wall panel 11 and the wall panel 12 are connected by a mortise and tenon joint structure, and the glue holes are filled with structural glue for fixation. Figure 8 As shown, the shell wall panel is pre-embedded with a screw sleeve, and the transition component and the wall panel are connected and fixed by screws.
