[0072] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0073] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied in the field of vehicle-mounted air purification technology.

[0074] With the rapid development of society and the continuous expansion of urban areas, people's demand for vehicles is increasing. At the same time, people spend more time in cars. However, the car itself is a relatively closed space with poor air circulation. The toxic gas in the car will be a major threat to people's health.

[0075] Research has found that currently, all methods for purifying the air in the car require manual work, such as the owner manually opening the window for ventilation, or the owner actively adjusting the air purifier in the car to purify the air in the car. However, this method of actively purifying the air in the car does not take into account all factors, and the intelligent control effect is not good. A certain degree of human intervention is required to achieve the requirement of comfortable breathing.

[0076] Based on this, an embodiment of the present application provides a method for purifying in-vehicle air, which makes an accurate assessment based on the collected in-vehicle air quality data and adopts appropriate response strategies to keep the in-vehicle air quality within a healthy range and ensure the health of people in the vehicle.

[0077] See also Figure 1, Figure 1 The flowchart of a method for purifying in-vehicle air provided in an embodiment of the present application. The method for purifying in-vehicle air is applied to an in-vehicle air purification system, which includes a user terminal, a communication module, an air detection module and an electronic control unit. Figure 1 As shown in , an in-vehicle air purification method provided by an embodiment of the present application includes:

[0078] S101, the user terminal responds to the user's determination operation on any air detection mode, determines a target air detection mode, and sends mode information corresponding to the target air detection mode to the communication module.

[0079] It should be noted that the user end is mainly used to respond to the user's selection and determination of the air detection mode. Here, the user end can be a mobile phone APP that communicates with the in-vehicle air purification system provided by this application, or it can be a display screen set on the vehicle, etc., and this application does not make specific restrictions on this. The air detection mode refers to a mode for detecting the air in the car. The specific air detection mode includes a VOC special detection mode, a combustible gas special detection mode, a toxic gas special detection mode, and an oxygen concentration special detection mode. Among them, the VOC special detection mode refers to a mode for detecting the concentration of volatile toxic gases such as interior decoration and glue, and the detection objects are hydrocarbons, aldehydes and ketones; the combustible gas special detection mode refers to a mode for detecting the concentration of combustible gases in the car, and the detection objects are methane, acetylene, biogas, oil gas, ethanol and other substances; the toxic gas special detection mode refers to a mode for detecting the concentration of toxic gases in the car, and the detection objects are chlorine dioxide, carbon monoxide and other toxic gases; the oxygen concentration special detection mode refers to a mode for detecting the oxygen concentration in the air in the car. The target air detection mode is any one of the above air detection modes selected by the user. The mode information is the information corresponding to the target air detection model. For example, when the target air detection mode is the VOC special detection mode, the mode information can be "VOC gas", which makes it convenient for the subsequent air detection module to directly determine the required detection tools based on the mode information.

[0080] For the above step S101, in the specific implementation, when the user selects and determines a certain air detection mode in the user terminal, the user terminal responds to the user's determination operation for any air detection mode, determines the target air detection mode, and sends the mode information corresponding to the target air detection mode to the communication module.

[0081] As an optional implementation, the air detection mode may also include a cyclic detection mode. Here, the cyclic detection mode refers to a mode in which the concentration of VOC gas, the concentration of combustible gas, the concentration of toxic gas and the concentration of oxygen in the vehicle are detected in sequence in a cyclic manner.

[0082] S102: The communication module receives the mode information sent by the user terminal, and sends the mode information to the air detection module.

[0083] It should be noted that the communication module is responsible for data transmission between various modules.

[0084] Regarding the above step S102, in specific implementation, after the user terminal generates and sends the mode information corresponding to the target air detection mode in step S101, the communication module receives the mode information sent by the user terminal and sends the mode information to the air detection module.

[0085] S103, the air detection module receives the mode information sent by the communication module, collects the vehicle's in-vehicle air quality data according to the mode information, and sends the in-vehicle air quality data to the electronic control unit.

[0086] It should be noted that the air detection module is responsible for detecting the air in the vehicle.

[0087] Regarding the above step S103, during the specific implementation, the air detection module receives the mode information sent by the communication module, collects the vehicle's in-car air quality data according to the mode information, and sends the collected in-car air quality data to the electronic control unit.

[0088] Here, the air detection module can use a pump-suction gas detector. The pump-suction gas detector is a single gas or multi-gas detector that can be flexibly configured. It can be equipped with VOC gas sensors, oxygen sensors, combustible gas sensors, and toxic gas sensors. Its working method is that the power supply drives the air pump to extract and sample the gas in the area to be tested, and then the sample gas is sent to the surface for testing. The characteristics of the pump-suction gas detector are fast detection speed, long-distance measurement of risk areas, and maintenance personnel safety.

[0089] Specifically, as an optional implementation, the air detection module includes a VOC detection unit, an in-vehicle combustible gas detection unit, an in-vehicle toxic gas detection unit, and an oxygen concentration detection unit; the in-vehicle air purification method also includes:

[0090] A: When the target air detection mode is the VOC special detection mode, the VOC detection unit detects the VOC gas concentration in the vehicle and uses the VOC gas concentration as the in-vehicle air quality data.

[0091] B: When the target air detection mode is the combustible gas special detection mode, the in-vehicle combustible gas detection unit detects the in-vehicle combustible gas concentration in the vehicle, and uses the in-vehicle combustible gas concentration as the in-vehicle air quality data.

[0092] C: When the target air detection mode is the toxic gas special detection mode, the in-vehicle toxic gas detection unit detects the in-vehicle toxic gas concentration in the vehicle, and uses the in-vehicle toxic gas concentration as the in-vehicle air quality data.

[0093] D: When the target air detection mode is the oxygen concentration special detection mode, the oxygen concentration detection unit detects the oxygen concentration in the vehicle, and uses the oxygen concentration as the in-vehicle air quality data.

[0094] For the above steps A to D, in the specific implementation, when the target air detection mode selected by the user is the VOC special detection mode, the VOC detection unit in the air detection module starts working to detect the VOC gas concentration in the vehicle, and the detected VOC gas concentration is used as the in-vehicle air quality data. When the target air detection mode selected by the user is the combustible gas special detection mode, the in-vehicle combustible gas detection unit in the air detection module starts working to detect the in-vehicle combustible gas concentration in the vehicle, and the detected in-vehicle combustible gas concentration is used as the in-vehicle air quality data. When the target air detection mode selected by the user is the toxic gas special detection mode, the in-vehicle toxic gas detection unit in the air detection module starts working to detect the in-vehicle toxic gas concentration in the vehicle, and the detected in-vehicle toxic gas concentration is used as the in-vehicle air quality data. When the target air detection mode selected by the user is the oxygen concentration special detection mode, the oxygen concentration detection unit in the air detection module starts working to detect the oxygen concentration in the vehicle, and the detected oxygen concentration is used as the in-vehicle air quality data.

[0095] As an optional implementation, the vehicle air purification method provided in the embodiment of the present application further includes:

[0096] When the target air detection mode selected by the user is the cycle detection mode, the VOC detection unit, the in-vehicle combustible gas detection unit, the in-vehicle toxic gas detection unit and the oxygen concentration detection unit in the air detection module perform data detection in sequence according to a preset detection order and a preset detection interval, and use the detected VOC gas concentration, the in-vehicle combustible gas concentration, the in-vehicle toxic gas concentration and the oxygen concentration as the in-vehicle air quality data.

[0097] It should be noted that the preset detection sequence refers to the preset detection sequence between each detection unit. For example, the preset detection sequence may be VOC detection unit-in-vehicle combustible gas detection unit-in-vehicle toxic gas detection unit-oxygen concentration detection unit, which is not specifically limited in this application. The preset detection interval refers to the preset detection time interval between each detection unit. For example, the preset detection interval may be preset to 30 minutes, which is not specifically limited in this application.

[0098] For the above steps, in the specific implementation, when the target air detection mode selected by the user is the cycle detection mode, the VOC detection unit, the in-vehicle combustible gas detection unit, the in-vehicle toxic gas detection unit and the oxygen concentration detection unit in the air detection module perform data detection in sequence according to the preset detection order and the preset detection interval, and the detected VOC gas concentration, in-vehicle combustible gas concentration, in-vehicle toxic gas concentration and oxygen concentration are used as the in-vehicle air quality data.

[0099] S104, the electronic control unit receives the in-vehicle air quality data sent by the air detection module, and controls the vehicle to purify the in-vehicle air according to the in-vehicle air quality data.

[0100] It should be noted that the electronic control unit is mainly responsible for controlling the equipment in the car according to the air quality data in the car to achieve the effect of air purification.

[0101] With respect to the above step S104, in step S103, the air detection module determines the in-vehicle air quality data, the electronic control unit receives the in-vehicle air quality data sent by the air detection module, and controls the vehicle to purify the in-vehicle air according to the in-vehicle air quality data.

[0102] Specifically, as an optional implementation, the air detection module further includes an outside-vehicle combustible gas detection unit and an outside-vehicle toxic gas detection unit. With respect to the above step S104, the electronic control unit controls the vehicle to purify the inside air according to the inside air quality data, including:

[0103] a: When it is detected that the VOC gas concentration is greater than or equal to a VOC gas concentration threshold, the windows in the vehicle are controlled to open, and the air purifier in the vehicle is controlled to turn on.

[0104] It should be noted that the VOC gas concentration threshold refers to a pre-set threshold used to determine whether the VOC gas concentration in the vehicle is too high.

[0105] For the above step a, when the target air detection mode is the VOC special detection mode, the in-vehicle air quality data includes the VOC gas concentration. After receiving the VOC gas concentration detected by the VOC detection unit, the electronic control unit determines whether the VOC gas concentration is greater than or equal to the VOC gas concentration threshold. If so, it is considered that the VOC gas concentration in the vehicle exceeds the standard, and the windows in the vehicle are controlled to open, and the air purifier in the vehicle is controlled to turn on to achieve the effect of air purification in the vehicle.

[0106] b: When it is detected that the combustible gas concentration inside the vehicle is greater than or equal to the combustible gas concentration threshold, the combustible gas detection unit outside the vehicle in the air detection module is controlled to turn on, and the combustible gas concentration outside the vehicle collected by the combustible gas detection unit outside the vehicle is received.

[0107] c: When it is determined that the concentration of the combustible gas inside the vehicle is lower than the concentration of the combustible gas outside the vehicle, the windows inside the vehicle are controlled to be closed.

[0108] d: When it is determined that the concentration of the combustible gas inside the vehicle is greater than or equal to the concentration of the combustible gas outside the vehicle, control the windows inside the vehicle to open.

[0109] It should be noted that the combustible gas concentration threshold refers to a pre-set threshold for determining whether the combustible gas concentration in the vehicle is too high. For example, the combustible gas concentration threshold may be pre-set to 25% LEL, which is not specifically limited in this application.

[0110] For the above steps b to d, when the target air detection mode is the combustible gas special detection mode, the in-vehicle air quality data includes the in-vehicle combustible gas concentration. After the electronic control unit receives the in-vehicle combustible gas concentration sent by the in-vehicle combustible gas detection unit, it determines whether the in-vehicle combustible gas concentration is greater than or equal to the combustible gas concentration threshold. If so, it is considered that the in-vehicle combustible gas concentration exceeds the standard, and the in-vehicle combustible gas detection unit in the air detection module is controlled to be turned on. The in-vehicle combustible gas detection unit is responsible for detecting the combustible gas concentration outside the vehicle. The air detection module receives the in-vehicle combustible gas concentration outside the vehicle collected by the in-vehicle combustible gas detection unit, and compares the in-vehicle combustible gas concentration with the in-vehicle combustible gas concentration outside the vehicle. When the electronic control unit determines that the in-vehicle combustible gas concentration is less than the in-vehicle combustible gas concentration, it is considered that the air outside the vehicle is poor, and the above step c is executed to control the windows in the vehicle to be closed to prevent the combustible gas outside the vehicle from being transmitted to the vehicle and to ensure the safety of the people in the vehicle. When the electronic control unit determines that the concentration of combustible gas in the vehicle is greater than or equal to the concentration of combustible gas outside the vehicle, it considers that the air inside the vehicle is poor, and executes the above step d to control the windows inside the vehicle to open, so as to transmit the combustible gas inside the vehicle to the outside of the vehicle and ensure the safety of the people inside the vehicle.

[0111] e: When it is detected that the toxic gas concentration inside the vehicle is greater than or equal to the toxic gas concentration threshold, the outside-vehicle toxic gas detection unit in the air detection module is controlled to turn on, and the outside-vehicle toxic gas concentration collected by the outside-vehicle toxic gas detection unit is received.

[0112] f: When it is determined that the concentration of toxic gases in the vehicle is lower than the concentration of toxic gases outside the vehicle, the windows in the vehicle are controlled to be closed, and the air purifier in the vehicle is controlled to be turned on.

[0113] g: When it is determined that the concentration of toxic gases in the vehicle is greater than or equal to the concentration of toxic gases outside the vehicle, control the windows in the vehicle to open.

[0114] It should be noted that the toxic gas concentration threshold refers to a pre-set threshold used to determine whether the toxic gas concentration in the vehicle is too high.

[0115] For the above steps e-g, when the target air detection mode is the toxic gas special detection mode, the in-vehicle air quality data includes the in-vehicle toxic gas concentration. After the electronic control unit receives the in-vehicle toxic gas concentration sent by the in-vehicle toxic gas detection unit, it determines whether the in-vehicle toxic gas concentration is greater than or equal to the toxic gas concentration threshold. If so, it is considered that the in-vehicle toxic gas concentration exceeds the standard, and the in-vehicle toxic gas detection unit in the air detection module is controlled to be turned on. The in-vehicle toxic gas detection unit is responsible for detecting the toxic gas concentration outside the vehicle. The air detection module receives the in-vehicle toxic gas concentration collected by the in-vehicle toxic gas detection unit, and compares the in-vehicle toxic gas concentration with the in-vehicle toxic gas concentration. When the electronic control unit determines that the in-vehicle toxic gas concentration is less than the in-vehicle toxic gas concentration, it is considered that the air outside the vehicle is poor, and the above step f is executed to control the windows in the vehicle to be closed to prevent the combustible gas outside the vehicle from being transmitted to the vehicle, to ensure the safety of the people in the vehicle, and to control the in-vehicle air purifier to be turned on to purify the air in the vehicle. When the electronic control unit determines that the concentration of toxic gases in the vehicle is greater than or equal to the concentration of toxic gases outside the vehicle, it considers that the air inside the vehicle is poor, and executes the above step g to control the windows inside the vehicle to open, so as to transmit the toxic gases inside the vehicle to the outside of the vehicle and ensure the safety of the people inside the vehicle.

[0116] h: When it is detected that the oxygen concentration is less than or equal to the first oxygen concentration threshold, a warning message is sent to the communication module, the oxygen concentration detection unit in the air detection module is controlled to detect the oxygen concentration in the vehicle according to the set detection frequency, and the oxygen concentration collected by the oxygen concentration detection unit is received.

[0117] i: When it is determined that the oxygen concentration is greater than a second oxygen concentration threshold and less than the first oxygen concentration threshold, the alarm light in the vehicle is controlled to turn on.

[0118] j: When it is determined that the oxygen concentration is less than the second oxygen concentration threshold, an alarm message is sent to the communication module.

[0119] It should be noted that the detection frequency refers to the detection frequency of the pre-set oxygen concentration detection unit. For example, the detection frequency can be pre-set to 5 minutes, which is not specifically limited in this application. The oxygen concentration threshold refers to a pre-set threshold for determining whether the oxygen concentration in the vehicle is too low. For example, the safe range of oxygen concentration is 19.5%-20.9%. At this time, the first oxygen concentration threshold can be set to 19.5%, and the second oxygen concentration threshold can be set to 15%. This application does not make specific limitations.

[0120] For the above steps h-j, when the target air detection mode is the oxygen concentration special detection mode, the air quality data in the vehicle includes oxygen concentration. After the electronic control unit receives the oxygen concentration detected and sent by the oxygen concentration detection unit, it determines whether the oxygen concentration is less than or equal to the first oxygen concentration threshold. If so, it is considered that the oxygen concentration in the vehicle is low. At this time, the electronic control unit first generates an early warning signal and sends the early warning signal to the communication module. The communication module sends the early warning signal to the user end, and the user end displays the early warning signal of low oxygen concentration. And the electronic control unit controls the oxygen concentration detection unit in the air detection module to detect the oxygen concentration in the vehicle according to the set detection frequency, and receives the oxygen concentration collected by the oxygen concentration detection unit. Then it is determined whether the oxygen concentration is within the safe range. If it is determined that the oxygen concentration is greater than the second oxygen concentration threshold and less than the first oxygen concentration threshold, it is considered that the oxygen concentration in the vehicle is low, and the alarm light in the vehicle is controlled to turn on to prompt the people in the car. When the electronic control unit determines that the oxygen concentration is less than the second oxygen concentration threshold, it is considered that the life safety of the people in the car has been endangered, and an alarm message is generated, and the alarm message is sent to the communication module. The communication module connects the vehicle emergency call unit according to the alarm message to provide manual rescue.

[0121] According to the embodiment provided by the present application, the in-vehicle air purification system further includes a server and a GPS positioning unit. The in-vehicle air purification method further includes:

[0122] (1) The air detection module sends the in-vehicle air quality data to the communication module.

[0123] (2) The GPS positioning unit sends the current location information of the vehicle to the communication module.

[0124] (3) The communication module receives the in-vehicle air quality data sent by the air detection module, receives the current location information sent by the GPS positioning unit, and sends the in-vehicle air quality data and the current location information to the server.

[0125] It should be noted that the server is responsible for collecting the in-vehicle air quality data and current location information in the vehicle, and performing big data analysis to determine the local area affected by harmful gases through data analysis and provide early warning. The GPS positioning unit is responsible for locating the vehicle.

[0126] In the specific implementation of the above steps (1) to (3), the air detection module sends the in-vehicle air quality data to the communication module, the GPS positioning unit sends the current location information of the vehicle to the communication module, the communication module receives the in-vehicle air quality data sent by the air detection module, receives the current location information sent by the GPS positioning unit, and sends the in-vehicle air quality data and the current location information to the server.

[0127] (4) The server receives the in-vehicle air quality data and the current location information sent by the communication module, and determines at least one adjacent vehicle and a first quantity corresponding to the at least one adjacent vehicle based on the current location information.

[0128] It should be noted that the distance between the adjacent vehicle and the vehicle is less than or equal to the distance threshold. Here, the distance threshold refers to a pre-set distance threshold for determining whether two vehicles are adjacent. For example, the distance threshold can be pre-set to 1 kilometer, which is not specifically limited in this application. The first number refers to the number of adjacent vehicles.

[0129] With respect to the above step (4), in a specific implementation, the server receives the in-vehicle air quality data and the current position information of the vehicle sent by the communication module, and determines at least one adjacent vehicle to the vehicle according to the current position information of the vehicle. Specifically, for example, the preset distance threshold is 1 km, and a range with a radius of 1 km is determined according to the current position information of the vehicle, all vehicles within the range are determined as adjacent vehicles, and a first number of all adjacent vehicles is determined.

[0130] (5) The server collects the reported data uploaded by the at least one adjacent vehicle, and determines whether there is data information exceeding a data threshold in the reported data.

[0131] (6) If yes, the server determines a second number of adjacent vehicles that have uploaded data information exceeding the data threshold, and when a ratio between the second number and the first number is greater than or equal to the ratio threshold, obtains a driving path corresponding to the vehicle set by the user terminal;

[0132] (7) The server determines at least one target vehicle currently traveling on the driving path based on the driving path, and sends area hazard warning information to the at least one target vehicle.

[0133] It should be noted that the reported data refers to the concentration information of substances in the air in the adjacent vehicles reported by the adjacent vehicles. The data threshold refers to the threshold corresponding to the reported data, which is used to determine whether the air is harmful. For example, if the reported data uploaded by the adjacent vehicle is the natural gas concentration in the vehicle, the data threshold can be set to 1%, and this application does not make specific restrictions on this. The second number refers to the number of adjacent vehicles that have uploaded data information exceeding the data threshold. The ratio threshold refers to a pre-set threshold value for whether the ratio between the second number and the first number is too large. For example, the ratio threshold can be pre-set to 50%, and this application does not make specific restrictions on this. The driving path refers to the driving route set by the owner in advance in the user terminal. The target vehicle refers to other vehicles traveling on the driving path. Regional hazard alarm information refers to information used to indicate the existence of danger in the area. Among them, the regional hazard alarm information includes the current location information.

[0134] Here, it should be noted that the above examples of reported data and data thresholds are only examples. In practice, reported data and data thresholds are not limited to the above examples.

[0135] For the above steps (5) to (7), in the specific implementation, after determining at least one adjacent vehicle adjacent to the vehicle, the server collects the reported data uploaded by at least one adjacent vehicle, and determines whether there is data information exceeding the data threshold in the reported data. If so, the above step (6) is executed, and the server determines the second number of adjacent vehicles that have uploaded data information exceeding the data threshold, and determines the ratio between the second number and the first number, and then determines whether the ratio between the second number and the first number is greater than or equal to the ratio threshold. When it is determined that the ratio between the second number and the first number is greater than or equal to the ratio threshold, the server obtains the driving path pre-set by the user on the user end of the vehicle, and determines at least one target vehicle currently traveling on the driving path according to the driving path, and then sends a regional danger alarm message carrying the current location information to at least one target vehicle to warn the owner of the target vehicle. In this way, in the in-vehicle air purification method provided in the present application, the vehicle end can upload the collected data to the server. Big data analysis can be used in the server to find that the air quality in a certain area is harmful, so that the owner who is about to enter this area can be reminded to take precautions.

[0136] The in-vehicle air purification method provided by the embodiment of the present application, first, the user end responds to the user's determination operation for any air detection mode, determines the target air detection mode, and sends the mode information corresponding to the target air detection mode to the communication module; then, the communication module receives the mode information sent by the user end, and sends the mode information to the air detection module; the air detection module receives the mode information sent by the communication module, collects the in-vehicle air quality data of the vehicle according to the mode information, and sends the in-vehicle air quality data to the electronic control unit; finally, the electronic control unit controls the vehicle to perform in-vehicle air purification according to the in-vehicle air quality data. In this way, the present application collects different in-vehicle air quality data through the air detection mode selected by the user, makes an accurate assessment based on the collected in-vehicle air quality data, and adopts appropriate response strategies to keep the in-vehicle air quality within a healthy range and ensure the health of the people in the vehicle.
