[0008] Furthermore, the window status recognition module recognizes the window status of the windows, specifically, recognizes the degree of opening of each window of the vehicle through image recognition technology. If the degree of opening of all windows is zero, the window status of the vehicle is fully closed; if the degree of opening of all windows is less than or equal to a preset degree threshold and there is a window whose degree of opening is greater than zero, then the window status of the vehicle is slightly open; if there is a window whose degree of opening is greater than the preset degree threshold, then the window status of the vehicle is fully open.

[0021] Embodiment 1 The present invention provides a low-carbon and energy-saving vehicle-mounted disinfection and purification system, which comprises a ventilation and purification device and a detection and control system, wherein the ventilation and purification device is communicatively connected with the detection and control system.

[0022] See also Figure 1 As shown, the detection and control system includes: an in-vehicle air quality analysis module, an outside-vehicle air quality analysis module, a window status recognition module and a control module, and a central processing unit that is communicatively connected to the above modules. The in-vehicle air quality analysis module is used to analyze the air pollution index of the vehicle's internal environment.

[0023] See also Figure 2 As shown, the in-vehicle air quality analysis module includes: a first sensor array and a first analysis module.

[0024] The first sensor array is used to obtain concentration data of different pollutants in the vehicle through a variety of concentration sensors.

[0025] The pollutants include particulate matter (such as PM2.5), carbon monoxide, volatile organic compounds (VOCs) and other substances harmful to the human body, as well as carbon dioxide.

[0026] The first analysis module is used to calculate the air pollution index of the vehicle interior environment according to the concentration data obtained by the first sensor array.

[0027] The first analysis module calculates the vehicle interior environment air pollution index, specifically: Preset weights are assigned to each pollutant detected in the vehicle in advance, and the sum of the products of the concentration of each pollutant detected in the vehicle and the corresponding preset weights is used as the vehicle internal environment air pollution index.

[0028] It should be noted that the sum of the preset weights of various pollutants detected in the vehicle is equal to 1.

[0029] For example: the types of pollutants in the car are A, B and C, the corresponding concentration data are C1, C2 and C3, and the corresponding preset weights are K1, K2 and K3. At this time, the vehicle's internal ambient air pollution index is K1×C1+K2×C2+K3×C3.

[0030] The outdoor air quality analysis module is used to analyze the comprehensive outdoor air pollution index ZWAP.

[0031] See also Figure 3 As shown, the vehicle exterior air quality analysis module includes: a second sensor array, a second analysis module, an image analysis module, an external data acquisition module and a comprehensive analysis module.

[0032] The second sensor array is used to obtain concentration data of different pollutants outside the vehicle through a variety of concentration sensors.

[0033] The second analysis module is used to calculate the first vehicle exterior air pollution index WAP1 according to the concentration data acquired by the second sensor array.

[0034] The second analysis module calculates the first vehicle exterior environment air pollution index, specifically: Preset weights are allocated in advance to the pollutants detected outside the vehicle, and the sum of the products of the concentrations of the pollutants detected outside the vehicle and the corresponding preset weights is used as the first vehicle exterior air pollution index.

[0035] The sum of the preset weights of the pollutants detected outside the vehicle is equal to 1.

[0036] The image analysis module is used to identify smoke information of the vehicle exterior environment through image recognition technology, and analyze the second vehicle exterior environment air pollution index WAP2 according to the smoke information.

[0037] The image analysis module identifies smoke information outside the vehicle through image recognition technology, specifically: Acquire multiple images of the vehicle's exterior environment through multi-angle cameras; Preprocess the image of the vehicle's exterior environment; The image of each vehicle's exterior environment is segmented into regions through the region growing algorithm and then feature information is extracted; According to the extracted feature information, the smoke and dust areas in each vehicle exterior environment image are identified through a trained deep learning model; Calculate the ratio B of the total number of pixels occupied by all smoke and dust areas to the total number of pixels of all vehicle exterior environment images, and the average grayscale value G of the smoke and dust areas; the average grayscale value of the smoke and dust areas is the ratio of the sum of the grayscale values ​​of the total pixels occupied by all smoke and dust areas to the total number of pixels occupied by all smoke and dust areas; Calculate the second vehicle exterior environment air pollution index WAP2, WAP2=EK1×B+EK2×G, EK1 and EK2 are the smoke area weight and smoke concentration weight respectively.

[0038] The external data acquisition module is used to connect with the authoritative official platform to obtain the third vehicle external environment air pollution index WAP3.

[0039] The authoritative official platform can be any relevant official platform such as a government environmental protection department or a meteorological service platform.

[0040] By connecting with the authoritative official platform, the third vehicle external environment air pollution index is obtained. Specifically, the vehicle location information is obtained through the vehicle positioning system, such as Beidou positioning, GPS, etc., and the third vehicle external environment air pollution index of the corresponding area is obtained through the authoritative official platform according to the vehicle location information.

[0041] The comprehensive analysis module is used to calculate a comprehensive external air pollution index ZWAP according to the first external air pollution index, the second external air pollution index and the third external air pollution index.

[0042] The comprehensive analysis module calculates the comprehensive vehicle exterior air pollution index ZWAP, specifically: ZWAP=WK1×WAP1+WK2×WAP2+WK3×WAP3, WK1, WK2 and WK3 are the preset trust coefficients of the first external air pollution index, the second external air pollution index and the third external air pollution index respectively, and WK1+WK2+WK3=1.

[0043] The air quality index is obtained through sensor array analysis, which can obtain the concentration of some types of pollutants in real time. It has strong real-time and accuracy, and can effectively improve the precision of the obtained pollutant concentrations. However, it is difficult to obtain the concentrations of a large number of pollutants, and it is impossible to comprehensively detect the concentrations of various pollutants. The air quality index is obtained through image recognition environmental smoke analysis. Since smoke, haze, etc. can be observed by camera, the degree of pollution of this type can be accurately obtained through image recognition, which can effectively assist the sensor array to identify abnormal data on particulate matter such as smoke. The air quality index is obtained through the official platform. Since the official equipment is usually strictly calibrated and its data is reviewed by professionals, the data quality is relatively high, but the official data is usually given for a large area, and the update frequency is usually low, which may not capture rapid changes in air quality.

[0044] Therefore, this solution combines the air quality index obtained through sensor array analysis, the air quality index obtained through image recognition environmental smoke analysis, and the air quality index obtained through docking with the official platform, and then calculates the comprehensive outdoor air pollution index. It combines the advantages of the three and complements each other's corresponding defects, thereby ensuring the effectiveness and accuracy of the comprehensive outdoor air pollution index.

[0045] The vehicle window status recognition module is used to recognize the vehicle window status, which includes fully closed state, slightly open state and fully open state.

[0046] The window state recognition module recognizes the window state of the vehicle windows, specifically, recognizes the degree of opening of each window of the vehicle through image recognition technology. If the degree of opening of all windows is zero, the window state of the vehicle is fully closed; if the degree of opening of all windows is less than or equal to a preset degree threshold and there is a window whose degree of opening is greater than zero, the window state of the vehicle is slightly open; if there is a window whose degree of opening is greater than the preset degree threshold, the window state of the vehicle is fully open.

[0047] The control module is used to control the start and stop, circulation mode and wind speed of the ventilation and purification device according to the vehicle's internal environment air pollution index, the comprehensive vehicle external environment air pollution index and the vehicle's window status.

[0048] See also Figure 4 As shown, the control module includes: a start-stop control module, a circulation mode control module and a wind speed control module.

[0049] The start-stop control module is used to determine whether a preset start strategy is met based on the air pollution index of the vehicle's internal environment and the real-time status of the windows, and if so, to start the ventilation and purification device.

[0050] The preset activation strategy is specifically: The vehicle's windows are in a fully closed state or a slightly closed state, and the vehicle's internal ambient air pollution index is greater than or equal to a preset internal index threshold.

[0051] The circulation mode control module is used to adjust the circulation mode for the ventilation and purification device according to the vehicle's internal environment air pollution index and the comprehensive vehicle external environment air pollution index when it is detected that the ventilation and purification device is in the turned-on state. The circulation mode includes an internal circulation mode and an external circulation mode.

[0052] The circulation mode control module adjusts the circulation mode for the ventilation purification device, specifically: If the air pollution index of the vehicle's internal environment is less than the comprehensive air pollution index of the vehicle's external environment, the ventilation and purification device is adjusted to the internal circulation mode, and when the duration of the ventilation and purification device maintaining the internal circulation mode is greater than the first preset duration, the ventilation and purification device is switched to the external circulation mode and maintained for a second preset duration before switching back to the internal circulation mode and recalculating the duration of maintaining the internal circulation mode; If the vehicle's internal ambient air pollution index is greater than or equal to the comprehensive external ambient air pollution index, the ventilation and purification device is adjusted to the external circulation mode.

[0053] It should be noted that, during the adjustment and switching process of the circulation mode, the start-stop control module determines in real time whether the preset start strategy is met, and automatically shuts down the ventilation and purification device if it is not met.

[0054] In this scheme, the internal circulation mode of the ventilation and purification device prevents more seriously polluted external air from entering the vehicle by closing the channel for introducing external air, and recycles the air in the vehicle. During the recycling process, the filter, ultraviolet lamp and photocatalyst net in the ventilation and purification device are used for sterilization and purification, temporarily reducing the air pollution index inside the vehicle. However, since there is no fresh air supplied, the consumption of oxygen caused by breathing, the accumulation of carbon dioxide and the infiltration of carbon monoxide produced by the engine will cause health damage to the people in the vehicle. At this time, it is necessary to switch to the external circulation mode to supply purified fresh air for a period of time. If the ventilation and purification device still needs to be turned on, and the air pollution index inside the vehicle is still less than the comprehensive air pollution index outside the vehicle, switch to the internal circulation mode and repeat the previous steps.

[0055] Generally speaking, the energy consumption of the internal circulation mode is lower than that of the external circulation mode. When the ventilation and purification device uses the external circulation mode, external air needs to be introduced, which will cause additional airflow disturbances, and the engine needs to provide more energy to overcome this additional resistance.

[0056] Therefore, this solution uses a circulation mode control module to adjust the circulation mode according to different data conditions, ensuring effective ventilation and purification while saving energy and achieving low-carbon energy saving.

[0057] The wind speed control module is used to adjust the wind speed of the ventilation and purification device according to the air pollution index of the vehicle interior environment when it is detected that the ventilation and purification device is in the turned-on state.

[0058] The wind speed control module adjusts the wind speed of the ventilation and purification device, specifically: The ventilation and purification device is provided with a minimum adjustable wind speed and a maximum adjustable wind speed. When the air pollution index of the vehicle's interior environment is equal to the preset internal index threshold, the ventilation and purification device is adjusted to the minimum adjustable wind speed. As the air pollution index of the vehicle's interior environment increases, the wind speed is automatically increased to the maximum adjustable wind speed.

[0059] Embodiment 2 The present invention also provides a low-carbon and energy-saving vehicle-mounted disinfection and purification method, which is applied to the above-mentioned low-carbon and energy-saving vehicle-mounted disinfection and purification system, and specifically comprises the following steps: S1. Obtaining concentration data of different pollutants inside the vehicle and concentration data of different pollutants outside the vehicle; S2, calculating the vehicle interior air pollution index according to the concentration data of different pollutants in the vehicle, and calculating the vehicle exterior air pollution index ZWAP according to the first vehicle exterior air pollution index WAP1, the second vehicle exterior air pollution index WAP2 and the third vehicle exterior air pollution index WAP3; S3, identifying the window status of the vehicle, the window status including fully closed state, slightly open state and fully open state; S4. Performing start-stop control, circulation mode control and wind speed control on the ventilation and purification device according to the vehicle's internal environment air pollution index, the comprehensive vehicle external environment air pollution index and the vehicle's window status.

[0060] For step S1 , the concentration data of different pollutants inside the vehicle and the concentration data of different pollutants outside the vehicle can be obtained by using a sensor array for detecting air quality.

[0061] For step S2, the vehicle interior ambient air pollution index is calculated based on the concentration data of different pollutants in the vehicle, specifically by pre-assigning preset weights to each pollutant detected in the vehicle, and taking the sum of the products of the concentration of each pollutant detected in the vehicle and the corresponding preset weights as the vehicle interior ambient air pollution index.

[0062] The first outside-vehicle air pollution index is calculated based on the concentration data of different pollutants outside the vehicle, specifically by pre-assigning preset weights to each pollutant detected outside the vehicle, and taking the sum of the products of the concentrations of each pollutant detected outside the vehicle and the corresponding preset weights as the first outside-vehicle air pollution index.

[0063] The second vehicle exterior environment air pollution index is obtained by calculating and identifying smoke and dust information of the vehicle exterior environment using image recognition technology, and is specifically: Acquire multiple images of the vehicle's exterior environment through multi-angle cameras; Preprocess the image of the vehicle's exterior environment; The image of each vehicle's exterior environment is segmented into regions through the region growing algorithm and then feature information is extracted; According to the extracted feature information, the smoke and dust areas in each vehicle exterior environment image are identified through a trained deep learning model; Calculate the ratio B of the total number of pixels occupied by all smoke and dust areas to the total number of pixels of all vehicle exterior environment images, and the average grayscale value G of the smoke and dust areas; the average grayscale value of the smoke and dust areas is the ratio of the sum of the grayscale values ​​of the total pixels occupied by all smoke and dust areas to the total number of pixels occupied by all smoke and dust areas; Calculate the second vehicle exterior environment air pollution index WAP2, WAP2=EK1×B+EK2×G, EK1 and EK2 are the smoke area weight and smoke concentration weight respectively.

[0064] The third vehicle exterior environment air pollution index is obtained by connecting with an authoritative official platform, and the authoritative official platform may be any relevant official platform such as a government environmental protection department or a meteorological service platform.

[0065] Calculate the comprehensive vehicle external ambient air pollution index ZWAP, specifically: ZWAP=WK1×WAP1+WK2×WAP2+WK3×WAP3, WK1, WK2 and WK3 are the preset trust coefficients of the first external air pollution index, the second external air pollution index and the third external air pollution index respectively, and WK1+WK2+WK3=1.

[0066] For step S3, the window status of the vehicle windows is identified by specifically identifying the degree of opening of each window of the vehicle through image recognition technology. If the degree of opening of all windows is zero, the window status of the vehicle is fully closed; if the degree of opening of all windows is less than or equal to a preset degree threshold and there is a window whose degree of opening is greater than zero, the window status of the vehicle is slightly open; if there is a window whose degree of opening is greater than the preset degree threshold, the window status of the vehicle is fully open.

[0067] In step S4, the start-stop control determines whether the preset opening strategy is met according to the vehicle interior ambient air pollution index and the real-time state of the window, and if so, the ventilation and purification device is turned on. The preset opening strategy is specifically: the vehicle window state is fully closed or slightly closed, and the vehicle interior ambient air pollution index is greater than or equal to the preset internal index threshold.

[0068] Circulation mode control, when it is detected that the ventilation and purification device is in the on state, the circulation mode of the ventilation and purification device is adjusted according to the vehicle internal environment air pollution index and the comprehensive vehicle external environment air pollution index. The circulation mode includes an internal circulation mode and an external circulation mode. Specifically: If the air pollution index of the vehicle's internal environment is less than the comprehensive air pollution index of the vehicle's external environment, the ventilation and purification device is adjusted to the internal circulation mode, and when the duration of the ventilation and purification device maintaining the internal circulation mode is greater than the first preset duration, the ventilation and purification device is switched to the external circulation mode and maintained for a second preset duration before switching back to the internal circulation mode and recalculating the duration of maintaining the internal circulation mode; If the vehicle's internal ambient air pollution index is greater than or equal to the comprehensive external ambient air pollution index, the ventilation and purification device is adjusted to the external circulation mode.

[0069] When the wind speed control detects that the ventilation and purification device is in the on state, the wind speed of the ventilation and purification device is adjusted according to the vehicle's internal environmental air pollution index. Specifically, the ventilation and purification device is provided with a minimum adjustment wind speed and a maximum adjustment wind speed. When the vehicle's internal environmental air pollution index is equal to the preset internal index threshold, the ventilation and purification device is adjusted to the minimum adjustment wind speed. As the vehicle's internal environmental air pollution index increases, the wind speed is automatically increased to the maximum adjustment wind speed.
