[0025] The following is combined Figures 1-3 This invention describes the vehicle-mounted handwashing basin control system and its control method.

[0026] Figure 1 This is one of the structural schematic diagrams of the vehicle-mounted handwashing basin control system provided by this utility model, such as... Figure 1 As shown, the vehicle-mounted handwashing station control system includes: a target sensor 100, a command input module 200, and a control module 300.

[0027] The target sensor 100 is installed inside the target water tank of the vehicle handwashing sink. The target sensor 100 includes at least two of the following: a water level sensor, a temperature sensor, and a pH value sensor. The target water tank includes at least one of a clean water tank and a wastewater tank.

[0028] In this embodiment, the target sensor 100 can be installed on the inner wall of the target water tank of the vehicle handwashing station and kept partially or completely submerged in water to accurately measure the water level.

[0029] For example, the water level sensor is usually installed on the lower part of the inner wall of the water tank, ensuring that the sensor body is in contact with the water.

[0030] In this embodiment, the target sensor 100 can be a float-type, capacitive, or ultrasonic water level sensor.

[0031] In this embodiment, the water level information can reflect the remaining water volume in the clean water tank and the capacity usage of the wastewater tank; the water temperature information can be used to display the current water temperature or as a basis for the control module 300 to adjust the water temperature; the pH value can indicate to the user whether the water quality is safe and whether it needs to be replaced.

[0032] In some embodiments, the target sensor 100 includes a water level sensor, a temperature sensor, and a pH value sensor; wherein the water level sensor is used to collect water level information, the temperature sensor is used to collect water temperature information, the pH value sensor is used to collect pH value data of the water stored in the target water tank, and the pH value data is used to calculate water quality health information.

[0033] In this embodiment, the number of various sensors deployed can be one or more, and joint detection by multiple sensors can ensure data reliability.

[0034] For example, the target sensor 100 of the RV's onboard handwashing basin is a water level sensor, installed in the fresh water tank and the waste water tank. An ultrasonic water level sensor is installed in the fresh water tank, located at the top of the tank, which measures the distance from the water surface by reflecting ultrasonic waves, thereby calculating the water level. At the same time, a float-type water level sensor is installed in the waste water tank. The float rises as the water level rises, causing a potentiometer to change its resistance, thereby measuring the water level. During the RV's travel, the water level in the fresh water tank gradually decreases, and the target sensor 100 monitors the water level information in real time for subsequent data analysis and display.

[0035] This embodiment enables real-time and accurate monitoring of the water levels in the clean water tank and wastewater tank of the vehicle-mounted handwashing station by installing one or more target sensors 100 inside the target water tank.

[0036] The instruction input module 200 is connected to the target sensor 100.

[0037] In this embodiment, the instruction input module 200 may be at least one of the display screen 210 and the voice recognition module 220.

[0038] The display screen 210 is used to display target parameters in real time. For example, the display screen 210 can display the sensing data measured by each sensor, and can also display the change in the sensing data.

[0039] In this embodiment, user commands can be voice input, touch input, gesture input, or key input.

[0040] In this embodiment, users can conveniently control various functions of the handwashing basin by operating the command input module 200, thereby enhancing the user experience.

[0041] The control module 300, the target sensor 100, and the command input module 200 are respectively connected to the control module 300. The control module 300 adjusts the target parameters of the water volume stored in the target water tank according to the command input by the user. The target parameters include at least two of the following: water level, water temperature, and pH value of the target water tank.

[0042] In this embodiment, the control module 300 can control the water inlet or outlet of the water tank according to the current user needs, and can also issue alarms based on the real-time water storage in the water tank, water level, water temperature or water quality status.

[0043] Specifically, the control module 300 converts the instructions input by the instruction input module 200 into electrical signals (i.e., control signals) and sends the electrical signals to the drive unit (such as the relay control unit 320) to drive the relay to turn on the water pump or close the valve to adjust the water level of the target water tank.

[0044] In addition, the control module 300 can also adjust the water tank according to user instructions and real-time measured sensor data; for example, when the sensor detects that the water level in the clean water tank is too low, the control module 300 can control the water pump to inject water into the clean water tank from an external water source; when the user adjusts the water level and water temperature of the water tank through the display screen 210, the control module 300 can control the water pump to inject water into the clean water tank from an external water source and control the heating device to adjust the water temperature.

[0045] For example, in cold weather, if a user wants to wash their hands with warm water, they can input a heating command through the display screen 210 to set the desired water temperature. After receiving the "heat" command, the control module 300 first reads the current water temperature, then calculates the temperature difference that needs to be heated. Based on the temperature difference, the control module 300 adjusts the heating power to avoid overheating or underheating. At the same time, the control module 300 monitors the current of the heating device to prevent overload. If the current water level in the tank is too low, the control module 300 will disable heating to prevent the heating device from burning dry. After receiving the "disable heating" command, the control module 300 controls the heating device to start working and displays the current heating status and water temperature information on the display screen 210. When the water temperature reaches the temperature set by the user, the control module 300 stops heating and issues a prompt sound to inform the user that they can wash their hands with warm water.

[0046] The vehicle-mounted handwashing basin control system provided in this embodiment of the utility model, by setting a target sensor 100 inside the target water tank of the vehicle-mounted handwashing basin, can monitor the water volume, temperature, and pH value stored in the target water tank. By setting an instruction input module 200, it can receive user instructions in real time. By setting a control module 300, it can generate control instructions based on at least one of the sensor data and user instructions, and adjust the target parameters of the water volume stored in the target water tank. Through the coordinated work of the target sensor 100, the instruction input module 200, and the control module 300, intelligent control of the vehicle-mounted handwashing basin is realized, improving the control efficiency and practicality of the vehicle-mounted handwashing basin.

[0047] In some embodiments, the instruction input module 200 includes a display screen 210; the display screen 210 displays the target parameters.

[0048] In this embodiment, the display screen 210 may be a touch LCD display screen 210, and a graphical user interface is integrated.

[0049] For example, when a user uses the sink in the RV, the display screen 210 will show the water level of the fresh water tank and the wastewater tank in real time, presented in an intuitive chart format.

[0050] In this embodiment, the water level display on the display screen 210 can be a bar chart, which can clearly show the percentage of remaining water; at the same time, the water temperature display can be a digital display with heating / cooling indicator icons, while the water quality display uses color coding, for example, green indicates good water quality, yellow indicates average water quality, and red indicates poor water quality.

[0051] The vehicle-mounted handwashing basin control system provided in this embodiment of the utility model, by setting up a display screen 210 and displaying target parameters, can help users intuitively view the liquid level, water temperature, pH value and their changes in each water tank, making it convenient for users to make handwashing basin control decisions quickly based on the viewed screen.

[0052] In some embodiments, the display screen 210 includes at least one function control, with different function controls corresponding to different parameters.

[0053] In this embodiment, the display screen 210 has a built-in microphone for receiving and broadcasting real-time voice messages; the display screen 210 may also include multiple virtual buttons, each corresponding to a different function; the display screen 210 may also include multiple physical buttons, each corresponding to a different function, and users can adjust the water temperature, set water level alarms, etc. by touching these buttons; the display screen 210 also has a built-in smart chip, and users can also adjust the water level and water temperature in the water tank by gesture control.

[0054] Specifically, users can turn the clean water valve and wastewater valve on or off, and adjust the water temperature, using the virtual buttons on the touchscreen display 210. For example, clicking the "Heat" button will bring up a temperature adjustment slider, which users can slide to set the target water temperature.

[0055] In this embodiment, if the water quality sensor detects that the water quality is substandard, a warning message will pop up on the display screen 210 to remind the user to change the water source or clean the water tank.

[0056] In this embodiment, functional controls refer to interactive elements such as virtual buttons, sliders, and menus on the display screen 210 used to perform specific functions. Different functional controls can be set according to the user's operating habits.

[0057] In this embodiment, when a user touches a function control, the display screen 210 converts the touch event into a corresponding control command and sends it to the control module 300 for execution. For example, touching the "heat" button will generate a "turn on heating" control command.

[0058] In one feasible embodiment, the display screen 210 of the vehicle-mounted handwashing station is a capacitive touchscreen and integrates the following function controls: Water level display area: Displays the water level height of the clean water tank and the wastewater tank in a bar chart. Users can set the water level alarm threshold by sliding the slider above the bar chart.

[0059] Water temperature adjustment area: Displays the current water temperature and provides "+" and "-" buttons to adjust the water temperature. Users can click the "+" button to increase the water temperature and click the "-" button to decrease the water temperature. In addition, a temperature slider can be set on the display screen 210, and users can directly drag the slider to set the target water temperature.

[0060] Water pump control area: Provides "on" and "off" buttons to control the water pump. Users can click the "on" button to start the water pump and supply water to the faucet; click the "off" button to stop the water pump.

[0061] Mode selection area: Offers options such as "Water Saving Mode", "Standard Mode" and "Powerful Mode", allowing users to select different modes to adjust the water pump's output and water temperature.

[0062] Settings Menu: Offers more advanced settings options, such as language selection, unit settings, calibration, etc. Users can click the "Settings" button to enter the settings menu and make personalized settings.

[0063] In this embodiment, the implementation of touch operation using the above-mentioned display screen 210 will be described as follows: (1) Adjusting water temperature: When the user touches the "+" button in the water temperature adjustment area, the display screen 210 will convert the touch event into a "raise water temperature" control command and send it to the control module 300; the control module 300 controls the heating device to start working and displays the new water temperature value on the display screen 210.

[0064] (2) Setting a water level alarm: The user touches the bar chart in the water level display area and slides the slider above the bar chart to set the threshold for the water level alarm. The display screen 210 converts the slider position information into a control command to "set the water level alarm threshold" and sends it to the control module 300; the control module 300 stores the new threshold in the memory and issues an alarm when the water level is below the threshold.

[0065] The vehicle-mounted handwashing basin control system provided in this embodiment of the utility model allows users to easily control various functions of the handwashing basin through the design of touch input and functional controls, and to make personalized settings according to their own needs, thereby improving the flexibility and efficiency of user operation.

[0066] In some embodiments, the instruction input module 200 further includes a voice recognition module 220; The speech recognition module 220 is used to perform endpoint detection, noise cancellation and sound information recognition on the user's speech input in sequence to obtain the user's instructions.

[0067] In this embodiment, users input commands via voice instead of traditional touch or physical buttons. Scenarios requiring voice input include: when it is inconvenient to touch the screen, or when commands need to be input quickly.

[0068] In this embodiment, the speech recognition module 220 is used to convert the user's speech into text or instructions. Specifically, the speech recognition module 220 typically includes the following steps: Endpoint detection: Detects the start and end points of speech to determine valid speech segments.

[0069] Noise cancellation: Reduces the impact of environmental noise on speech recognition and improves recognition accuracy.

[0070] Voice recognition: Converting speech into text or commands. This typically requires the use of acoustic and language models.

[0071] Figure 2 This is a schematic diagram of the working mechanism of the speech recognition system provided by this utility model. Figure 2In the illustrated embodiment, the speech recognition system (corresponding) speech recognition module includes speech acquisition, endpoint detection, noise cancellation, feature extraction, decoding, and speaker cancellation units. When a user issues a voice command, the speech recognition system acquires the voice command through a microphone, converting the analog speech signal into a digital signal that the machine can recognize. After the speech acquisition is completed, the next step is endpoint detection, which separates the speech signal from the non-speech signal time period to accurately determine the starting point of the speech signal time period. Next is noise cancellation. In the in-vehicle environment, in addition to the user's voice command, there is also noise from in-vehicle equipment and the surrounding environment. Noise cancellation can filter out useless environmental noise and improve recognition accuracy. The next step is feature extraction, which extracts the feature parameters of the speech signal. The fifth step is back-end decoding. Back-end decoding refers to the process of using trained "acoustic models" and "language models" to recognize (also called "decode") the extracted feature vectors and obtain text information. The main purpose of the acoustic model is to calculate the probability of speech features to syllables (or phonemes), and the main purpose of the language model is to calculate the probability of syllables to characters. The most important part of the decoder is to score the original speech features using the acoustic model and the language model, and on this basis, obtain the optimal path of the word pattern sequence. The text corresponding to this path is the final recognition result. Finally, the recognition result is sent to the MCU unit through a serial communication line, and the recognized text information is played out through the speaker.

[0072] In this embodiment, the display screen 210 of the vehicle-mounted handwashing basin integrates a voice recognition module 220. For example, the display screen 210 has a built-in microphone array for collecting the user's voice. At the same time, the display screen 210 is also equipped with a high-performance processor for running voice recognition algorithms. In this way, the user can control various functions of the handwashing basin by voice.

[0073] In this embodiment, the voice recognition module supports both offline and online voice recognition modes. In offline mode, the voice recognition module 220 uses pre-trained acoustic and language models to perform voice recognition without a network connection. In online mode, the voice recognition module 220 connects to a cloud-based voice recognition service to obtain more accurate recognition results.

[0074] For example, if the user command is "turn on the tap," the speech recognition module 220 will sequentially perform endpoint detection, noise cancellation, and sound information recognition to convert the speech into the text "turn on the tap." Then, the speech recognition module 220 will match the text with predefined control commands to generate a control command "turn on the water pump," and send it to the control module 300.

[0075] The vehicle-mounted handwashing basin control system provided in this embodiment of the utility model includes a voice recognition module 220, which sequentially performs endpoint detection, noise cancellation, and sound information recognition on voice input to obtain control commands. Users can control various functions of the handwashing basin by voice when it is inconvenient to touch the screen, thus improving the convenience and safety of use.

[0076] In some embodiments, the voice recognition module 220 further includes a power amplifier circuit 221.

[0077] In this embodiment, the power amplifier circuit 221 is used to play the voice information obtained by converting the electrical signal, which is generated based on the voice input.

[0078] In this embodiment, the power amplifier circuit 221 is used to amplify the weak electrical signal to a sufficient power to drive the speaker to emit sound; the power amplifier circuit 221 in this embodiment is used to play the voice information obtained by converting the electrical signal, which can be the feedback information of the voice recognition module 220 or the system prompt tone.

[0079] In this embodiment, a digital signal is converted into an analog electrical signal by a digital-to-analog converter (DAC), and then amplified by a power amplifier circuit 221 to drive the sound emitted by the speaker. This voice information can be pre-recorded or synthesized in real time.

[0080] In this embodiment, the voice recognition module 220 of the vehicle-mounted handwashing station integrates a power amplifier circuit 221 and a speaker, which can provide voice feedback to the user.

[0081] Specifically, the voice recognition module 220 includes a DAC chip to convert digital voice signals into analog electrical signals, while the power amplifier circuit 221 uses a Class D power amplifier chip, and a high-sensitivity speaker is selected to ensure clear sound quality.

[0082] The vehicle-mounted handwashing basin control system provided in this embodiment of the utility model, by setting a power amplifier circuit 221, can play voice information converted from electrical signals. The voice feedback can promptly inform the user of the system status and guide the user to operate, thereby improving the usability and ease of use of voice interaction.

[0083] In some embodiments, the instruction input module includes a display screen and a voice recognition module; the control module includes: an MCU control unit, with the display screen and the voice recognition module respectively connected to the MCU control unit; and a relay control unit, which is connected to the MCU control unit and is used to control the relay to drive the water pump or the drain valve.

[0084] In this embodiment, the relay control unit 320 is used to control high-voltage or high-current circuits; specifically, the relay control unit 320 receives control signals from the MCU and controls the relay to drive the water pump or sewage valve to work according to the control signals.

[0085] In this embodiment, the MCU control unit is connected to the voice recognition module via a serial communication line and to the display screen via an RS232 communication line; the relay control unit is connected to the MCU control unit via a signal line.

[0086] In this embodiment, the MCU control unit 310 is used to receive sensor data, receive user instructions, generate control instructions, and control various actuators; the relay control unit 320 is used to control the relay to drive the water pump or the sewage valve according to the control instructions.

[0087] In this embodiment, the MCU is connected to the voice recognition module 220 of the display screen 210 via a serial communication cable to receive control commands or text information output by the voice recognition module 220; the serial communication protocol used in this embodiment can be UART, RS232 or RS485, etc.

[0088] For example, the MCU is connected to the display screen 210 via an RS232 communication line to send display data and receive touch input.

[0089] In this embodiment, the control module 300 uses an STM32 series MCU as the control core and is equipped with a relay control unit 320.

[0090] Figure 3 This is the second structural schematic diagram of the vehicle-mounted handwashing basin control system provided by this utility model. Figure 3In the illustrated embodiment, the vehicle-mounted handwashing basin control system comprises a voice recognition system, an LCD touchscreen, an MCU control unit, a relay control unit, a water pump, a drain valve, a water tank, and water pipes. The voice recognition system, upon recognizing a correct voice command, plays a prompt tone and transmits the recognition result to the MCU control unit via a serial communication line. Upon receiving the recognition result, the MCU control unit controls the relay unit via a signal line. Based on different recognition results, the relay unit controls the operation of the water pump and the drain valve respectively. When the water pump is operating, it draws water from the clean water tank to the water basin via the water pipes. Once the clean water reaches the water basin, it is ready for use. The clean water tank contains a built-in level sensor, which transmits the clean water level data to the MCU unit via a signal line. Upon receiving the clean water level status, the MCU unit transmits the clean water level data to the touchscreen LCD display via an RS232 bus. The touchscreen LCD display receives the clean water level data, processes it, and displays the data as a chart on the screen. After receiving the clean water level data, the MCU will compare it with the preset clean water warning level data. If it is lower than the clean water warning level data, the MCU unit will send a command to the voice system through the serial communication line to play a warning prompt sound to remind the user to add clean water as soon as possible.

[0091] Figure 3 After use, the water in the greywater tank flows into the sewage tank through the sewage pipe. The sewage tank has a built-in level sensor, which is connected to the MCU unit via a signal line. The level sensor transmits the sewage level data to the MCU unit in real time via the signal line. After receiving the sewage level status, the MCU unit transmits the sewage level data to the touch screen LCD via the RS232 bus. After receiving the sewage level data, the touch screen LCD processes it and displays the sewage level data in the form of a chart on the screen. After receiving the sewage level data, the MCU compares it with the preset warning level data. If it is higher than the sewage warning level data, the MCU unit will send a command to the voice system via the serial communication line to play a warning sound, reminding the user to drain the sewage as soon as possible.

[0092] in addition, Figure 3 The LCD touchscreen has two virtual buttons: a water pump switch and a drain valve switch. When the drain valve button is pressed, the touchscreen transmits the drain command to the MCU control unit via the RS232 bus. After receiving the drain command, the MCU control unit controls the relay unit to open the drain valve via a signal line. Once the drain valve is open, the sewage in the sewage tank can be discharged through the drain valve via the water pipe.

[0093] The vehicle-mounted handwashing basin control system provided in this embodiment of the utility model achieves precise control of each actuator through the coordinated operation of the MCU control unit 310 and the relay control unit 320, while improving the reliability and maintainability of the system.

[0094] In some embodiments, the target water tank is equipped with a heating element.

[0095] In this embodiment, the water temperature can be controlled by adding a heating element to the target water tank.

[0096] For example, when a user observes that the water temperature in the tank is lower than the preset temperature on the display screen, they can click the "Heat" control on the display screen. The display screen will send the heating electrical signal to the MCU control unit. After the MCU control unit analyzes the electrical signal, it will generate the corresponding control signal based on the heating information and send it to the heating control unit to control the heating element to start the heating function.

[0097] In some embodiments, a cooling device may also be installed in the target water tank to control the water temperature to decrease. The control process is similar to the water temperature increase process, and will not be described in detail in this embodiment.

[0098] The vehicle-mounted handwashing basin control system provided in this embodiment of the utility model can control the water temperature rise in real time by setting a heating element in the target water tank, thereby meeting the user's hot water supply needs.

[0099] In some embodiments, the vehicle-mounted handwashing basin control system further includes a safety module 400, which is connected to the wastewater tank.

[0100] In this embodiment, the security module 400 can be a combination lock, installed at the switch of the sewage tank, to strictly control the discharge of sewage from the vehicle-mounted handwashing sink by controlling the opening and closing of the sewage tank.

[0101] In this embodiment, the safety module can also lock or unlock the vehicle-mounted handwashing station mechanism.

[0102] Among them, the vehicle-mounted handwashing basin mechanism refers to the various movable parts or overall structure of the vehicle-mounted handwashing basin; for example, the faucet can be locked to prevent accidental contact and leakage; the storage cabinet can be locked to prevent items from slipping out; the telescopic mechanism of the entire handwashing basin can be locked to prevent accidental deployment during driving.

[0103] In this embodiment, the safety module 400 may be a module for controlling the locking or unlocking of the vehicle-mounted handwashing basin mechanism (e.g., faucet, storage cabinet, telescopic mechanism of the entire handwashing basin, etc.), which can prevent unauthorized use or operation and improve security, especially during vehicle operation.

[0104] In this embodiment, the vehicle-mounted handwashing basin control system integrates a safety module 400 to prevent accidental contact with the faucet or handwashing basin mechanism while the vehicle is in motion.

[0105] In some embodiments, the safety module 400 includes an electromagnetic lock and a drive circuit.

[0106] The electromagnetic lock is used to lock the telescopic mechanism of the faucet and sink, and the drive circuit is used to control the opening and closing of the electromagnetic lock.

[0107] In one feasible embodiment, when the vehicle starts, the MCU receives a start signal from the vehicle's CAN bus and sends a "lock" command to the safety module 400. The safety module 400's drive circuit controls the electromagnetic lock to lock the telescopic mechanisms of the faucet and sink. The user can send an unlock request to the MCU via the "unlock" button on the touch display 210 or by saying the voice command "unlock sink". After the MCU authenticates the user (via fingerprint recognition or password input), it sends an "unlock" command to the safety module 400, and the safety module 400's drive circuit controls the electromagnetic lock to unlock, allowing the user to use the sink normally. When the vehicle is turned off, the MCU receives an engine shutdown signal from the vehicle's CAN bus and sends a "lock" command to the safety module 400. The safety module 400's drive circuit controls the electromagnetic lock to lock the telescopic mechanisms of the faucet and sink.

[0108] The vehicle-mounted handwashing basin control system provided in this embodiment of the utility model improves safety by integrating a safety module, preventing safety hazards caused by accidental contact during vehicle operation, and further enhancing the user experience.

[0109] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
