[0063] The following description of exemplary embodiments of the present invention is made in conjunction with the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding. These details should be considered as merely exemplary. Therefore, it should be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0064] At present, air quality sensors are used to detect air quality. Particle concentration sensors are used to measure harmful gases such as CO2, NO x and CH4, etc. In addition, due to the complexity of the airway, the detection object of the air quality sensor is mostly a single air source, such as detecting the air inside the vehicle.

[0065] Both the air outside the vehicle and the air inside the vehicle will directly or indirectly affect the health of the driver and passengers, but it is difficult to control the air quality inside the vehicle in a timely manner.

[0066] In order to timely control the air quality inside the vehicle, the following technical solutions in the embodiments of the present invention may be adopted.

[0067] Figure 1 FIG is a schematic diagram of the main structure of an air quality measurement device according to an embodiment of the present invention. Figure 1 The air quality measuring device 100 includes an outside air intake 101 , an outside air detector 102 and an air exhaust 103 , and an inside air intake 104 and an inside air detector 105 .

[0068] The outside air detector 102 and the inside air detector 105 are enclosed in the same housing. As an example, the outside air detector 102 and the inside air detector 105 are enclosed in the housing of an air quality detection device. The air quality detection device detects the air outside the vehicle using the outside air intake 101, the outside air detector 102, and the exhaust 103, and detects the air inside the vehicle using the inside air intake 104, the inside air detector 105, and the exhaust 103.

[0069] Specifically, the following Figure 1 Explain the use of air quality measurement equipment to monitor the air outside the vehicle.

[0070] The outside air of the vehicle is input into the outside air detector 102 through the outside air air inlet 101. After detection by the outside air detector 102, the outside air detection result is determined and provided. The outside air detector 102 is connected to the exhaust port 103 to discharge the outside air of the vehicle output by the outside air detector 102.

[0071] While the air quality measuring device detects the air outside the vehicle, it can also detect the air inside the vehicle. Figure 1 Explain the use of air quality measurement equipment to monitor the air inside a vehicle.

[0072] The interior air of the vehicle is input into the interior air detector 105 through the interior air inlet 104 . After detection by the interior air detector 105 , the interior air detection result is determined and provided. The interior air detector 105 is connected to the exhaust port 103 to discharge the interior air of the vehicle output by the interior air detector 105 .

[0073] In one embodiment of the present invention, the external air detector 102 is further used to generate an external control signal based on the detection results of the air outside the vehicle, and send the external control signal to the vehicle system, so that the vehicle system controls the external circulation damper K1 of the vehicle air conditioner based on the external control signal, and displays the detection results of the air outside the vehicle.

[0074] exist Figure 1In this embodiment, an external air detector 102 is used to detect and determine an external air detection result. Based on the external air detection result, an external control signal can be sent to the vehicle-mounted system, causing the vehicle-mounted system to control the external circulation damper K1 of the vehicle air conditioner based on the external control signal. As an example, if the external air detection result is poor, the vehicle-mounted system controls the external circulation damper K1 of the vehicle air conditioner to close to prevent external air from contaminating the vehicle's interior environment. As another example, if the external air detection result is good, the vehicle-mounted system controls the external circulation damper K1 of the vehicle air conditioner to fully open to improve the air quality within the vehicle's interior environment.

[0075] In addition, the vehicle display device can be controlled through the vehicle system to display the external air detection results, making it easier for users to operate based on the external air detection results.

[0076] In one embodiment of the present invention, the interior air detector 105 is further used to generate an internal control signal based on the detection results of the interior air of the vehicle, and send the internal control signal to the vehicle system, so that the vehicle system controls the fresh air system K2 or the window K3 based on the internal control signal, and displays the detection results of the interior air of the vehicle.

[0077] exist Figure 1 In an embodiment, an interior air detector 105 is used to detect and determine an interior air detection result. An interior control signal can be sent based on the interior air detection result to control the vehicle's fresh air system K2 or window K3. As an example, if the interior air detection result is poor, the vehicle-mounted system controls the fresh air system K2 to open or open window K3 based on the interior control signal, thereby achieving convection between the vehicle's interior air and the air outside the vehicle, thereby improving the vehicle's interior air quality. As another example, if the interior air detection result is excellent, the vehicle-mounted system controls the fresh air system K2 to close or close window K3 based on the interior control signal, thereby maintaining excellent vehicle interior air quality.

[0078] In addition, the internal air detection results can also be displayed, and the user can operate based on the internal air detection results.

[0079] In one embodiment of the present invention, an air quality measurement device simultaneously monitors both the air outside and inside the vehicle, displaying both the external and internal air quality measurements. The vehicle's air conditioning, ventilation system, and windows can be controlled by the vehicle's computer system based on these measurements.

[0080] It can be understood that with the external air detection results and the internal air detection results as trigger conditions, the vehicle system controls the vehicle air conditioning, fresh air system and windows, thereby ensuring the air quality inside the vehicle.

[0081] See also Figure 2 , Figure 2 FIG1 is a schematic diagram of the main structure of an external air detector according to an embodiment of the present invention. The external air detector 102 includes a first gas detector QT1 and a first particle detector KL1.

[0082] The air outside the vehicle first passes through the first gas detector QT1 and then the first particle detector KL1. This is because the risk of hazardous gases is far greater than the impact of particulate matter concentration. As an example, if the first gas detector QT1 determines that the concentration of hazardous gases in the air outside the vehicle exceeds the alarm threshold, an alarm will be immediately issued, triggering the closure of the external circulation damper of the vehicle's air conditioner. For example, if the first gas detector QT1 detects that the carbon dioxide concentration in the air outside the vehicle exceeds the alarm threshold in a vehicle tank filled with R744 CO2 refrigerant, an alarm will be immediately issued.

[0083] Specifically, air outside the vehicle is input into a first gas detector QT1, where it is tested to determine the concentration of harmful gases. The output of the first gas detector QT1 is then input into a first particle detector KL1 to determine the concentration of particulate matter. Based on the harmful gas and particulate matter concentrations, the vehicle computer system controls the external air circulation damper of the vehicle's air conditioner and displays these concentrations.

[0084] For example, the vehicle's system can send external control signals based on the concentration of harmful gases and particulate matter in the air outside the vehicle, and control the air circulation damper of the vehicle's air conditioner. Furthermore, the concentration of harmful gases and particulate matter can be displayed on the vehicle's display screen.

[0085] The first particle detector KL1 is connected to the exhaust port 103 to discharge the vehicle outside air outputted from the first particle detector KL1.

[0086] In one embodiment of the present invention, the harmful gases detected by the first gas detector QT1 include one or more of the following: nitrogen oxides, carbon monoxide, carbon dioxide and methane.

[0087] exist Figure 2 In the embodiment, the first gas detector QT1 is first used to detect the concentration of harmful gases, and then the first particle detector KL1 is used to detect the concentration of particulate matter, which effectively reduces the adverse effect of the air outside the vehicle on the air inside the vehicle.

[0088] See also Figure 3 , Figure 3Figure 2 is a schematic diagram of the main structure of a first particle detector KL1 according to an embodiment of the present invention. The first particle detector KL1 includes a heater JR and a particle laser module KLJ. Considering that water vapor in the air can affect the accuracy of particle concentration, water vapor can be removed from the air outside the vehicle to improve the accuracy of particle concentration. Specifically, water vapor is removed from the air outside the vehicle before it enters the particle laser module KLJ, which measures particle concentration. As an example, the heater JR is used to remove water vapor from the air outside the vehicle.

[0089] The outside air output from the first particle detector KL1 is fed into a heater JR, which heats the air to remove water vapor. The heater JR then outputs the de-watered air to a particle laser module KLJ, which determines the particle concentration in the air. The particle laser module KLJ is connected to an exhaust port 103 to discharge the air output from the particle laser module.

[0090] In one embodiment of the present invention, the heater JR comprises a resistance wire, which can be provided in a transmission duct of the vehicle's external air to remove water vapor from the vehicle's external air.

[0091] In one embodiment of the present invention, the particle laser module KLJ can detect the concentration of particle matter.

[0092] See also Figure 4 , Figure 4 FIG2 is a schematic diagram of the main structure of an internal air detector according to an embodiment of the present invention. The internal air detector 105 includes a second gas detector QT2 and a second particle detector KL2.

[0093] Air from the vehicle's interior is input to a second gas detector QT2, which detects and determines the carbon dioxide concentration in the vehicle's interior air. The second gas detector QT2 then inputs the air from the vehicle's interior to a second particle detector KL2, which determines the particulate matter concentration in the vehicle's interior air. Based on these concentrations, the second particle detector KL2 controls the vehicle's ventilation system or windows, and displays these concentrations.

[0094] Interior air detector 105 detects the air inside a vehicle. Vehicle interior air often contains carbon dioxide and common particulate matter. Second gas detector QT2 detects carbon dioxide concentration, while second particle detector KL2 detects particulate matter concentration. For example, particulate matter concentrations include one or more of the following: PM2.5 and PM1.0.

[0095] In an embodiment of the present invention, the outside air detector 102 and the inside air detector 105 share an exhaust port 103. That is, both the air outside the vehicle and the inside of the vehicle are discharged through the exhaust port 103. As an example, the exhaust port 103 has a Y-shaped structure, with both ends of the Y-shaped structure connected to the outside air detector 102 and the inside air detector 105, respectively, and the remaining end of the Y-shaped structure of the exhaust port 103 communicating with the outside of the vehicle.

[0096] In addition, to improve the effectiveness of exhaust gas from the exhaust port 103, a check valve may be provided at the connection point between the Y-shaped structure of the exhaust port 103 and the outside of the vehicle. As an example, the check valve includes one of the following: a spring check valve, a swing check valve, a lift check valve, and an exhaust check valve.

[0097] See also Figure 5 , Figure 5 FIG. 4 is a schematic diagram of the main structure of another air quality measurement device according to an embodiment of the present invention.

[0098] Can be Figure 1 The air quality measuring device is provided with a first fan F1 and / or a second fan F2. Figure 5 Air quality measurement equipment and Figure 1 The difference between the air quality measuring device and the conventional air quality measuring device is that a first fan F1 and a second fan F2 are provided.

[0099] The air quality measurement device further includes a first fan F1 disposed at the vehicle exterior air intake 101 and a second fan F2 disposed at the vehicle interior air intake.

[0100] The air outside the vehicle is input into the external air detector 102 through the external air inlet 101 by a first fan F1 , and the air inside the vehicle is input into the internal air detector through the internal air inlet 104 by a second fan F2 .

[0101] The first fan F1 is used to increase the amount of air entering the vehicle through the exterior air inlet 101 and prevent the air from entering the vehicle through the exhaust port 103. The second fan F2 is used to increase the amount of air entering the vehicle through the interior air inlet 104 and prevent the air from entering the vehicle through the exhaust port 103.

[0102] See also Figure 6 , Figure 6 FIG. 4 is a schematic structural diagram of an operating air quality measurement device according to an embodiment of the present invention. Figure 6In this system, air quality measurement equipment is used to simultaneously monitor both the air outside and inside the vehicle. The exterior air intake 101, first fan F1, first gas detector QT1, heater JR, particulate matter laser module KLJ, exhaust port 103, interior air intake 104, second fan F2, second gas detector QT2, and particulate matter detector KL2 are housed in the same housing.

[0103] Figure 6 The solid line represents the air passage for detecting the air outside the vehicle, and the dotted line represents the air passage for detecting the air inside the vehicle.

[0104] The air passage for detecting the air outside the vehicle is specifically as follows: the air outside the vehicle enters the first gas detector QT1 through the outside air air inlet 101 and the first fan F1. The first gas detector QT1 detects and obtains the concentration of harmful gases. The outside air of the vehicle output by the first gas detector QT1 is input to the heater JR. The heater JR heats the outside air of the vehicle to remove water vapor, and the heater JR outputs the outside air of the vehicle with water vapor removed to the particulate matter laser module KLJ. The particulate matter laser module KLJ determines the particulate matter concentration of the outside air of the vehicle. The particulate matter laser module KLJ is connected to the exhaust port 103 to discharge the outside air of the vehicle output by the particulate matter laser module KLJ. According to the concentration of harmful gases and particulate matter, the vehicle system can control the external circulation damper K1 of the vehicle air conditioner based on the external control signal.

[0105] The airflow path for detecting vehicle interior air is as follows: Vehicle interior air enters the second gas detector QT2 through the vehicle interior air intake 104 and the second fan F2. Second gas detector QT2 detects and determines the carbon dioxide concentration. The vehicle interior air output from second gas detector QT2 is input to particle detector KL2. Particle detector KL2 determines the particle concentration in the vehicle interior air. Particle detector KL2 is connected to exhaust port 103 to discharge the vehicle interior air output from particle detector KL2. Based on the carbon dioxide concentration and the particle concentration in the vehicle interior air, the vehicle computer system can control the vehicle's fresh air system K2 or windows K3 based on internal control signals.

[0106] See also Figure 7 , Figure 7 FIG. 1 is a schematic diagram of the position of an air quality measurement device according to an embodiment of the present invention.

[0107] Figure 7 Reference numeral 106 denotes the vehicle's dash panel, which is the partition between the engine compartment and the vehicle interior. The air quality measurement device is located between the dash panel and the vehicle interior to facilitate the collection and discharge of air outside and inside the vehicle.

[0108] The air outside the vehicle is input into the outside air intake port 101 through the opening of the vehicle's front panel via the air intake hose set in the air intake duct, and the air inside the vehicle is input into the inside air intake port 104 through the air intake hose 107 set in the vehicle compartment; the exhaust port 103 is output to the cockpit through the air outlet hose through the opening of the vehicle's front panel.

[0109] In one embodiment of the present invention, the air quality measurement device may be applied to a vehicle.

[0110] See also Figure 8 , Figure 8 Figure 8 This is a flow chart of a vehicle control method implemented based on an air quality measurement device according to an embodiment of the present invention. The air quality measurement device can implement the vehicle control method. Specifically, the following steps are included:

[0111] S801: Receive detection results of the air outside the vehicle and the air inside the vehicle.

[0112] Receives the test results of the vehicle's external air and the vehicle's internal air sent by the air quality measurement equipment, thereby achieving vehicle control.

[0113] S802. Control the vehicle.

[0114] The vehicle is controlled based on the detection results of the vehicle's external air and the vehicle's internal air. As an example, the vehicle's display device is controlled to display the vehicle's external air and internal air detection results. For example, the vehicle's internal display displays the vehicle's external air and internal air detection results.

[0115] In one embodiment of the present invention, an external control signal and / or an internal control signal transmitted by an air quality measurement device are received. The external control signal is generated by the air quality measurement device based on the detection results of the air outside the vehicle, and the internal control signal is generated by the air quality measurement device based on the detection results of the air inside the vehicle. The external circulation damper of the vehicle air conditioner is controlled based on the external control signal; the fresh air system or windows are controlled based on the internal control signal.
