DETAILED DESCRIPTION
[0011] Exemplary embodiments of the application are described below with reference to the accompanying drawings, which include various details of the embodiments of the application to help in understanding, and should be considered only as exemplary. Therefore, those skilled in the art should realize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the application. Also, in order to be clear and concise, the description below omits the description of well-known functions and structures.
[0012] An embodiment of the application provides a vehicle-mounted health monitoring system, which comprises a vehicle-mounted air conditioner, a vehicle-mounted oxygen bar, a seat with a massage function and a vehicle machine. Figure 1 is a schematic view of a vehicle-mounted oxygen bar and two oxygen outlets provided by an embodiment of the application.
[0013] Referring to Figure 1 , the vehicle-mounted oxygen bar comprises an air inlet filter, an oil-free scroll air compressor, an electromagnetic valve, a molecular sieve tower A / B, an oxygen storage tank, a nitrogen exhaust silencer, a pressure regulating valve, a check valve, a switching switch, a first oxygen outlet and a second oxygen outlet.
[0014] The intake filter is used to filter dust, particulate matter and other impurities in the air entering the oxygen bar. The oil-free scroll air compressor compresses the air to a certain pressure to provide power for subsequent oxygen separation. The solenoid valve is used to switch the pressurization and exhaust process of the two molecular sieve towers A / B, realizing continuous oxygen production. The molecular sieve tower A / B separates oxygen and nitrogen in the air. The oxygen storage tank stores the produced oxygen, balances the system pressure, and ensures the stability of the oxygen output. During the molecular sieve tower regeneration (exhaust) process, the high-pressure nitrogen gas is quickly discharged, which produces noise, and the silencer is used to reduce noise. The pressure regulating valve is used to adjust the pressure of the output oxygen. The check valve prevents reverse flow of gas and ensures that oxygen can only flow from the tank to the output. The first oxygen outlet is on the rearview mirror, which delivers pure oxygen to the rearview mirror, and then disperses it into the car. The second oxygen outlet is at the air outlet of the air conditioner, which disperses pure oxygen into the car through the air outlet of the air conditioner. The car machine control switch realizes the switching of the first oxygen outlet and the second oxygen outlet, so as to deliver pure oxygen to the rearview mirror or the air outlet of the air conditioner. The vehicle-mounted oxygen bar is in communication connection with the car machine, for example, through the CAN network connection.
[0015] The car machine detects the current scene mode of the intelligent cabin; specifically, the car machine collects the user's voice, remote operation (of the mobile phone) or large-screen touch operation; for example, the user clicks "sleep mode" on the mobile phone application or calls "sleep mode" by voice. According to the voice recognition result, remote operation or touch point, determine the current scene mode of the intelligent cabin, such as sleep mode, long-distance driving mode, etc.
[0016] According to the current scene mode, the first oxygen outlet or the second oxygen outlet is opened, and according to the current scene mode, the oxygen output rate, the air conditioner air volume and the seat state are controlled. For example, in sleep mode, the second oxygen outlet is opened, the oxygen output mode enters the dispersion working mode of the air conditioner air outlet, the oxygen concentration of the vehicle-mounted oxygen bar is maintained at a certain target oxygen content, the oxygen output rate is controlled at a set value, the air conditioner air volume is set to two levels, the internal circulation, the sleep white noise is opened by default for a set period of time, and the one-key sleep seat is automatically flattened. For another example, in long-distance driving mode, the first oxygen outlet is opened, the oxygen outlet mode is changed to the directional oxygen output mode at the rearview mirror end, the oxygen output speed is accelerated, the oxygen concentration at the driver's position is maintained at a certain target oxygen content, and the air conditioner air volume is set to a set value, so that the driver is refreshed and awake, and fatigue is prevented.
[0017] Optionally, if the current scene mode requires the vehicle-mounted oxygen bar to be turned on, the vehicle window is automatically controlled to close after a reminder (such as a voice reminder "window is being closed"), the vehicle door is reminded to be closed, and the vehicle-mounted air conditioner is set to internal circulation and the default air speed. Optionally, the user can directly click to turn on the vehicle-mounted oxygen bar on the mobile terminal application or the vehicle terminal application, at which time the vehicle terminal reminds the vehicle door and the vehicle window to be closed, and if they are not closed within a timeout period, the vehicle door and the vehicle window are automatically controlled to be closed. The air conditioner is automatically controlled to adjust to internal circulation, and the default air speed is two gears.
[0018] The real-time oxygen content is displayed on the vehicle terminal screen, and a change curve and an icon of the oxygen content are drawn, so that the occupant can accurately know the current oxygen content in the vehicle. In an example, when the oxygen content reaches a certain set percentage level, a dynamic bubble prompt is displayed on the vehicle terminal screen that the current environment is a "forest oxygen bar" environment, and when the oxygen content reaches a certain set percentage or above, a dynamic reminder is displayed on the vehicle terminal screen that the current environment is a "rich oxygen environment" or a "life oxygen" environment.
[0019] The system further includes an oxygen concentration sensor; the oxygen concentration sensor is arranged within a set range (for example, 50 cm to 60 cm) of the first oxygen outlet and the second oxygen outlet; the oxygen concentration sensor is used to detect the real-time oxygen content in the vehicle and transmit the real-time oxygen content to the vehicle terminal; and the vehicle terminal adjusts the oxygen output in real time according to the real-time oxygen content, so that the target oxygen content in the vehicle is reached.
[0020] The system further includes an air bag sleeping mat; the controller of the seat and the controller of the air bag sleeping mat are connected to the vehicle terminal; and the vehicle terminal controls the massage amplitude, frequency and mode of the seat, and the pressure, expansion and folding state of the air bag sleeping mat according to the current scene mode or the instruction of the user.
[0021] Figure 2 is a flowchart of a vehicle-mounted health monitoring method provided by an embodiment of the present application, which is applicable to a vehicle-mounted health monitoring system. The method provided by the embodiment is applicable to health monitoring of a driver and adjustment of the environment of the cabin to make the driver comfortable. Referring to Figure 2 The method provided by the embodiment is executed by the vehicle terminal and includes the following operations: S110, detecting a current scene mode of the intelligent cabin; S120, opening the first oxygen outlet or the second oxygen outlet according to the current scene mode, and controlling the oxygen output rate, the air conditioner air volume and the seat state according to the current scene mode.
[0022] The real-time oxygen content detected by the oxygen concentration sensor is required as feedback, and the vehicle terminal compares the real-time oxygen content with the target oxygen content to feedback and adjust the oxygen output and the oxygen output rate of the vehicle-mounted oxygen bar. However, the oxygen concentration sensor can only detect the current oxygen content and cannot predict the oxygen content at future time points or realize pre-adjustment of the oxygen content.
[0023] Based on the above problems, the following scheme is provided: after controlling the oxygen output rate, air conditioner air volume and seat state according to the current scene mode, referring to Figure 3 , the following steps are further included: Figure 2 , the following steps are further included: S130, acquiring the physiological state of the driver through the health perception device in the vehicle.
[0024] The health perception device can be an infrared camera installed in front of the driver to collect the driver's facial video through the infrared camera. The facial video is analyzed to obtain the blood volume change of the facial capillary, and the pulse signal is extracted according to the blood volume change to determine the physiological state of the driver. The physiological state includes heart rate value, heart rate variability, respiratory rate, blood oxygen saturation and blood pressure.
[0025] Specifically, based on the rPPG technology, the BVP signal is extracted by analyzing the color signal in the facial video. The physiological parameters such as heart rate value and respiratory rate are extracted from the BVP signal. For example, the heart rate value, heart rate variability (HRV) and other indicators are extracted through signal processing (such as filtering, peak detection).
[0026] Optionally, a hybrid model based on deep learning (combining CNN, LSTM and ViViT) estimates the heart rate and blood oxygen saturation (SpO2) from the facial video. Based on the two-stage framework of deep learning (DRP-Net and BBP-Net), the systolic blood pressure (SBP) and diastolic blood pressure (DBP) are estimated by analyzing the phase shift signal in the facial video.
[0027] S140, predicting the opening frequency and amplitude of the vehicle door and window in the future period according to the current vehicle state and the vehicle state.
[0028] The vehicle state includes the temperature and humidity in the vehicle, and the vehicle state includes the temperature, humidity and weather (such as rain, snow, wind, sunny, etc.) outside the vehicle. The vehicle window here should be extended to include the sunroof.
[0029] Optionally, a rule base is constructed in advance, including different vehicle states and different vehicle states, and the corresponding opening frequency and amplitude of the vehicle door and window in the future period. Through a large amount of investigation and statistics, the opening frequency and average opening amplitude of the vehicle door and window in the future 10 minutes under a certain vehicle state and vehicle state are constructed to construct the rule base.
[0030] The current vehicle interior state and the vehicle exterior state are matched in the rule base to determine the opening frequency and amplitude of the vehicle door and the vehicle window in the future period. Specifically, in one case, the current vehicle interior state and the vehicle exterior state are accurately matched in the rule base, and the opening frequency and amplitude of the vehicle door and the vehicle window in the future period stored in the rule base are determined, that is, the opening frequency and amplitude of the vehicle door and the vehicle window in the future period are directly read from the rule base. In another case, the current vehicle interior state and the vehicle exterior state cannot be accurately matched in the rule base, for example, the current vehicle interior temperature is 20 degrees, and the vehicle exterior temperature is 25 degrees, but the rule base does not have the opening frequency and amplitude at this temperature, a plurality of groups of vehicle interior state and vehicle exterior state located in the neighborhood of the current vehicle interior state and vehicle exterior state are determined. The "neighborhood" refers to a set range of the current vehicle interior state and vehicle exterior state. For example, the current vehicle interior temperature is 20 degrees, and the neighborhood is 18-22 degrees. The current vehicle exterior weather is light rain, and the neighborhood is overcast or heavy rain. In the rule base, the opening frequency and amplitude of the vehicle door and the vehicle window in the future period corresponding to each group of vehicle interior state and vehicle exterior state are determined; the opening frequency and amplitude of the vehicle door and the vehicle window in the future period are averaged, that is, the opening frequency and amplitude of the front left window in the future period are averaged, the opening frequency and amplitude of the front right window in the future period are averaged, the opening frequency and amplitude of the sunroof in the future period are averaged, the opening frequency and amplitude of all vehicle doors in the future period are averaged, and so on, to obtain the opening frequency and amplitude of the vehicle door and the vehicle window in the future period corresponding to the current vehicle interior state and vehicle exterior state.
[0031] S150, according to the oxygen content in the vehicle after ventilation, the oxygen consumption rate, the opening frequency and amplitude, the oxygen content in the vehicle space at the future time is predicted.
[0032] The oxygen content in the vehicle after ventilation refers to the oxygen content in the vehicle after the last ventilation operation of the vehicle, which should be consistent with the oxygen content of the external environment. The ventilation operation is, for example, the operation of opening all the windows or all the doors. The oxygen content of the external environment can be obtained from the local weather information.
[0033] When all the windows and all the doors are closed and the air conditioner is off or in internal circulation, it is the end time of ventilation. According to the oxygen consumption rate, the total oxygen consumption from the end time of ventilation to the current time is calculated. The oxygen consumption rate can be determined according to the number and age of the passengers. Adults consume about 240-300 milliliters of oxygen per minute in a quiet state, and children and the elderly consume about 200 milliliters of oxygen. Assuming that from the end time of ventilation t0 to the current time t1 is 10 minutes, the oxygen consumption rate of all passengers per minute is multiplied by 10 minutes to obtain the total oxygen consumption.
[0034] The oxygen content in the vehicle after ventilation is taken as an initial value, and the total oxygen consumption is subtracted to obtain the current total oxygen remaining. The current total oxygen remaining, the opening frequency and amplitude matched from the rule base are input into the prediction model to obtain the oxygen content in the vehicle space at the future time. The future time is the end time of the future period. For example, the current time is 2:00, the future period is 2:01-2:10, and the future time is 2:10.
[0035] The prediction model is a Transformer architecture or a long short-term memory neural network.
[0036] Specifically, an oxygen sensor is arranged in the vehicle in advance; the vehicle and the window are controlled at a set opening frequency and amplitude within a set period (for example, 5:00-5:10), the oxygen content at the end of the set period (for example, 5:10) and the oxygen content at the beginning of the set period (for example, 5:00) are read from the oxygen sensor; the oxygen content at the beginning of the set period, the set opening frequency and amplitude are taken as training samples, and the oxygen content at the end of the set period is taken as a label to train the prediction model; the prediction model is a Transformer architecture or a long short-term memory neural network. The opening frequency and amplitude are changed to collect more training samples. In this way, the trained prediction model can obtain the oxygen content at the end of the set period according to the oxygen content at the beginning of the set period, the opening frequency and amplitude of the vehicle door and window during the set period.
[0037] After the prediction model is trained, the current total oxygen remaining, the opening frequency and amplitude matched from the rule base are input into the prediction model to obtain the oxygen content in the vehicle space at the future time.
[0038] The embodiment does not need to install an oxygen concentration sensor in the vehicle, but directly obtains the oxygen content in the vehicle at the future time through the prediction model. Before using the prediction model for prediction, the prediction model needs to be trained.
[0039] S160, adjust the environment in the cabin according to the physiological state, the historical adjustment preference of the driver, the current state in the vehicle, the current state of the vehicle and the oxygen content at the future time. The adjustment dimensions include at least temperature, oxygen content and humidity.
[0040] The historical adjustment preference of the driver is the temperature, oxygen content and humidity that the driver adjusts under a certain physiological state and in-vehicle state in a historical period. For example, the average value of the in-vehicle temperature, the average value of the oxygen content and the average value of the humidity that the driver manually adjusts on the vehicle screen in the past 10 days under the fatigue state and a certain in-vehicle state are counted.
[0041] In this step, first, the required temperature, required oxygen content and required humidity in the vehicle are obtained according to the physiological state, historical adjustment preference and current in-vehicle state. That is, the physiological state of the driver and the current in-vehicle state are matched in the historical adjustment preference to obtain the temperature, oxygen content and humidity that the driver wants to adjust to as the required temperature, required oxygen content and required humidity in the vehicle at present.
[0042] Then, the required oxygen charging amount in the vehicle is determined according to the oxygen content at the future time and the required oxygen content. The oxygen content at the future time can be obtained according to the foregoing step. The required oxygen charging amount in the vehicle is obtained by subtracting the oxygen content at the future time from the required oxygen content, and the vehicle-mounted oxygen bar is controlled according to the oxygen charging amount, so that the oxygen charging is advanced and the comfort of the occupant is improved.
[0043] Then, the temperature adjustment range and the humidity adjustment range are determined according to the current vehicle state. The current vehicle state includes the remaining fuel amount or the remaining electric amount. If the remaining fuel amount or the remaining electric amount is less than a set threshold value, the vehicle power system should be mainly supplied. Therefore, the smaller the remaining fuel amount or the remaining electric amount is, the smaller the temperature adjustment range and the humidity adjustment range are. For example, if the remaining electric amount is 10%, the temperature adjustment range is -5~+5 degrees of the current temperature; if the remaining electric amount is 20%, the temperature adjustment range is -10~10 degrees of the current temperature.
[0044] Finally, the vehicle-mounted air conditioner is controlled in temperature according to the required temperature and the temperature adjustment range, and the vehicle-mounted air conditioner is controlled in humidity according to the required humidity and the humidity adjustment range.
[0045] Specifically, the required temperature is subtracted from the current temperature to obtain the required adjustment temperature amplitude, and if the temperature amplitude is within the temperature adjustment range, the vehicle-mounted air conditioner is controlled to adjust to the required temperature. If the temperature amplitude is not within the temperature adjustment range, the temperature is adjusted according to the limit value of the temperature adjustment range. For example, the required temperature is 25 degrees, the current temperature is 15 degrees, the temperature amplitude is 10 degrees, and the temperature adjustment range is -8~8 degrees, i.e. the temperature amplitude is not within the temperature adjustment range, so the temperature is adjusted according to 8 degrees, and finally the vehicle is adjusted to 15+8=23 degrees.
[0046] The humidity adjustment is the same, that is, the required humidity is subtracted from the current humidity to obtain the required adjustment humidity amplitude, and if the humidity amplitude is within the humidity adjustment range, the vehicle-mounted air conditioner is controlled to adjust to the required humidity. If the humidity amplitude is not within the humidity adjustment range, the humidity is adjusted according to the limit value of the humidity adjustment range.
[0047] The vehicle-mounted health monitoring method and system provided in the application can monitor the physiological state of the driver in real time through the health sensing device, predict the opening frequency and amplitude of the vehicle door and window in the future period, which is an important factor that can greatly affect the oxygen content in the vehicle. Then, the oxygen content in the vehicle space at the future time is predicted according to the oxygen content in the vehicle after ventilation, the oxygen consumption rate, the opening frequency and amplitude. It can be seen that the prediction algorithm is used to obtain the oxygen content at the future time, which makes up for the deficiency that the oxygen sensor is difficult to detect the oxygen content in the future period. Then, the environment in the cabin is adjusted based on the physiological state, the historical adjustment preference of the driver, the current vehicle state, the current vehicle state and the oxygen content at the future time, so as to comprehensively consider various factors to achieve the coordinated adjustment of temperature, humidity and oxygen content, especially the advanced adjustment of oxygen content, so that the driver is always in a comfortable state.
