Description

[0002] With the improvement of living standards, people have higher and higher requirements for the comfort of the vehicles they ride. The domestic passenger car interior environment pollution control is slightly better, but it is not optimistic, and the commercial vehicle (for example, a bus) is more serious. Now, whether for long-distance road transport or for urban public transportation, the bus is most sought after for noise reduction, beauty and luxury, and more and more full-enclosed window structures are used - most of the glass windows cannot be opened, so that the harmful chemical gases emitted in the vehicle are more likely to accumulate and are difficult to quickly discharge.

[0003] On the other hand, in the fully enclosed cabin of the bus, due to the large density of the members in the vehicle, the air in the vehicle is mixed through repeated circulation of the air conditioner, and it is very easy to spread the bacteria through the air. And with the increase of the riding time, the oxygen concentration in the vehicle decreases, and the CO2 concentration increases, which is not conducive to human health. Especially in summer, other odors emitted into the cabin are also difficult to remove. These can pose a great threat to the physical and mental health of passengers, and also have a serious impact on the comfort of riding, and even affect the driving of the driver, leading to traffic accidents. In addition, the air outside the vehicle is polluted by the environment, such as particulate matter, CO and nitrogen oxides entering the vehicle, which also affects human health and makes people feel tired, etc.

[0035] The applicant has also found in the process of filing the present application that there are various in-vehicle purification systems in the prior art, but for passenger vehicles with a larger vehicle cabin, an in-vehicle air purification system is mainly used in cooperation with an air conditioner. Most of them are in-circulation purification modes and use a non-independent fresh air system, i.e., the fresh air system is attached to the air inlet device of the in-vehicle air conditioner in order to improve the air inlet quality of the air conditioner. In the prior art, 10%-25% of fresh air is usually used to adjust the air quality.

[0036] The non-independent fresh air device has two limitations, one is that the fresh air volume is small, and the other is that it is attached to the air conditioner. When the air conditioner is not working, the non-independent fresh air device is difficult to function. In addition, when the temperature is high in summer, the passenger vehicle is in an unstarted state, and the interior of the passenger vehicle releases certain toxic or harmful gases such as benzene, toluene, ethylbenzene, styrene, formaldehyde, acetaldehyde, and propylene aldehyde at high temperature. When passengers enter the vehicle cabin, it is not good for human health. And the monitoring data cannot be dynamically monitored online, so that the application value of the in-vehicle air quality monitoring is low.

[0037] To solve the above problems, the embodiments of the present application provide an air quality monitoring method, system, device and medium, and the general idea is as follows:

[0038] The application provides an air quality monitoring system applied to a vehicle, the system comprising: a controller, an in-vehicle sensor group connected with the controller, an out-vehicle sensor group, an air purifier, a fresh air system, a control panel and a ventilation fan, wherein: the in-vehicle sensor group is arranged inside a vehicle cabin of the vehicle, and the out-vehicle sensor group is arranged outside the vehicle cabin of the vehicle; the air purifier is arranged below a seat in the vehicle cabin of the vehicle, and the fresh air system is arranged at a front end of a roof cover of the vehicle.

[0039] The controller is used to control the air purifier and / or the fresh air system to select a corresponding target mode to perform purification treatment on air in the vehicle cabin according to data collected by the in-vehicle sensor group and the out-vehicle sensor group.

[0040] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the accompanying drawings and specific embodiments.

[0041] Firstly, the term "and / or" appearing in the present text is only used to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in the present text generally represents an "or" relationship between the front and rear associated objects.

[0042] Please refer to Figure 1 , which is a structural schematic diagram of an air quality monitoring system provided by the application. As shown in Figure 1 , the system 10 is applied to a vehicle. The system 10 comprises: a controller 101, an in-vehicle sensor group 102 connected with the controller 101, an out-vehicle sensor group 103, an air purifier 104, a fresh air system 105, a control panel 106 and a ventilation fan 107. Wherein: the in-vehicle sensor group 102 is arranged inside a vehicle cabin of the vehicle, and the out-vehicle sensor group 103 is arranged outside the vehicle cabin of the vehicle; the air purifier 104 is arranged below a seat in the vehicle cabin of the vehicle, and the fresh air system 105 is arranged at a front end of a roof cover of the vehicle. The controller 101 is used to control the air purifier 104 and / or the fresh air system 105 to select a corresponding target mode to perform purification treatment on air in the vehicle cabin according to data collected by the in-vehicle sensor group 102 and the out-vehicle sensor group 103.

[0043] Optionally, the controller 101 can communicate (i.e. be in communication connection) with the in-vehicle sensor group 102 and the out-vehicle sensor group 103 through RS232. The air purifier 104 and the fresh air system 105 can be in communication connection with the controller 101 through a CAN bus.

[0044] Optionally, the system further comprises a purification selection module 108. The controller 101 is connected with the air purifier 104 and the fresh air system 105 through the purification selection module 108. The purification selection module 108 is used to select the air purifier 104 and / or the fresh air system 105 to purify the air in the vehicle. Specifically, the controller 101 can determine whether to adopt the internal circulation purification mode or the external circulation purification mode according to the gas concentration inside and outside the vehicle, and analyze the target mode of the air purifier 104 and / or the fresh air system 105, including the low-grade running mode, the middle-grade running mode, the high-grade running mode and the standby mode, etc. The fresh air system 105 can introduce 100% fresh air as needed. In this way, fresh air is provided in the vehicle, and polluted air in the vehicle is discharged, so that the air in the vehicle is kept clean. When the road condition is poor and the air outside the vehicle is worse than the air inside the vehicle, the internal circulation purification mode can be adopted. At this time, the independent fresh air system 105 no longer introduces fresh air, communicates through the CAN bus, and turns on the air purifier 104.

[0045] Optionally, the system can further comprise a purification indication module 109. The controller 101 is connected with the control panel 106 through the purification indication module 109.

[0046] Optionally, when measuring the gas concentration in the vehicle environment, the in-vehicle sensor group 102 is arranged / installed at the front, middle and rear positions of the luggage rack in the vehicle cabin, and can be connected with the data receiving module 110 of the controller 101 through RS232.

[0047] Correspondingly, when measuring the gas concentration outside the vehicle environment, the out-of-vehicle sensor group 103 can be arranged inside the bumper at the front and rear ends of the vehicle body, and can be connected with the data receiving module 110 of the controller 101 through RS232. Optionally, the number of the in-vehicle sensor group 102 and the out-of-vehicle sensor group 103 is not limited in the application, and can be one or more.

[0048] Further optionally, the in-vehicle sensor group 102 and the out-of-vehicle sensor group 103 can each be an infrared composite sensor, which can be used to collect information such as temperature, O2, CO2, VOC, CO, CH2O, PM 2.5 or other information, such as the concentration of other toxic or non-toxic gases. The types of gases to be detected by the in-vehicle sensor group 102 and the out-of-vehicle sensor group 103 are not limited in the application, and can be selected according to the actual needs of the user.

[0049] Accordingly, when purifying the air inside the vehicle, the air purifier 104 can be installed directly below the passenger seat in the car cabin and communicate with the data receiving module 110 of the controller 101 via a CAN bus. The fresh air system 105 can be an independent fresh air system, which can be installed at the front / front of the car roof and communicate with the data receiving module 110 of the controller 101 via a CAN bus.

[0050] In an optional embodiment, the system may further include a user terminal 111. The user terminal 111 has a communication module, such as a Bluetooth 4.0 communication module. The Bluetooth communication module of the user terminal 111 can communicate with the control panel 106. Optionally, a corresponding application (APP) can be installed on the user terminal. By viewing the in-vehicle air pollution concentration level displayed on the APP, the user can select the operating level of the air purifier 104 and the fresh air system 105, such as selecting any one of low, medium, or high settings, to purify the in-vehicle air quality in advance, demonstrating the system's intelligence.

[0051] Optionally, the system may further include a base station 112 and a remote server 113. The base station 112 can communicate with the user terminal 111 and the remote server 113 via a network. Further optionally, the user terminal 111, the base station 112, and the remote server 113 can communicate with the control panel 106 via a network. It should be noted that any one or more of the user terminal 111, the base station 112, and the remote server 113 may exist in the system 10; this application does not impose limitations. The air quality monitoring system 10 of this application can operate independently of the air conditioning system.

[0052] Optionally, the remote server 113 supports data interaction with the base station 112 via limited communication. This allows engineers to remotely monitor data collected by the in-vehicle / external sensor array and the operating status of various system components (e.g., actuators), and make corresponding decisions. This enables accurate, continuous, and effective monitoring of in-vehicle air quality, and facilitates more comprehensive optimization of the in-vehicle system performance, reducing implementation costs.

[0053] In an optional embodiment, the controller 101 can analyze and compare preset air quality parameters with the in-vehicle and out-of-vehicle gas concentration parameters received by the data receiving module 109 to achieve in-vehicle air purification. The preset air quality parameters are typically specified according to air quality standards; for example, please refer to [link to relevant documentation]. Figure 2 The pollution level diagram and pollution level table for air quality requirements inside a long-distance bus are shown in Table 1 below.

[0054] Table 1

[0055]

[0056] in, Figure 2 The S0, S1 and S2 mentioned in Table 1 above are all in-vehicle air pollution levels, and S2>S1>S0.

[0057] Based on the above embodiments, please refer to Figure 3 This is a flowchart illustrating an air quality monitoring method provided in an embodiment of this application. Figure 3 The method shown is applied to the air quality monitoring system described in the above embodiments, specifically to the controller 101 in the system. The method includes the following implementation steps:

[0058] S301. Obtain the in-vehicle temperature and in-vehicle gas concentration collected by the in-vehicle sensor group, and the outside temperature and outside gas concentration collected by the outside sensor group.

[0059] The vehicle interior temperature and the vehicle interior gas concentration mentioned in this application are both collected by an in-vehicle sensor array, and the vehicle exterior temperature and the vehicle exterior gas concentration are both collected by an external sensor array. This application does not limit the gases included in the vehicle interior gas concentration and the vehicle exterior gas concentration; for example, they may include oxygen, carbon dioxide, carbon monoxide, PM2.5, VOCs, CH2O (formaldehyde), benzene, or other gases.

[0060] S302. Determine the temperature difference between the inside and outside of the vehicle based on the inside temperature and the outside temperature.

[0061] The temperature difference between the inside and outside of the vehicle mentioned in this application is the difference between the temperature inside the vehicle and the temperature outside the vehicle, as shown in the following formula (1):

[0062] Δt=T in -T out Formula (1)

[0063] Among them, T in The temperature inside the vehicle, T ou t represents the outside temperature of the vehicle.

[0064] S303. Based on the temperature difference between inside and outside the vehicle, the gas concentration inside the vehicle, and the gas concentration outside the vehicle, the target device in the air quality monitoring system is controlled and operated in the corresponding target mode to purify the air inside the vehicle.

[0065] In one specific embodiment, both the in-vehicle gas temperature and the outside gas temperature include oxygen concentration, carbon dioxide concentration, and concentrations of m other gases. Step S303 can be implemented as follows: First, determine the temperature difference range based on the internal and external temperature difference. Then, within the temperature difference range, sequentially compare the concentrations of oxygen, carbon dioxide, and m other gases in the in-vehicle gas and the outside gas to determine the target mode of the target device in the air quality monitoring system. Specifically, for example, when comparing the concentrations of m other gases, this application can select the same target device with the highest operating level from the m comparison results to correspond to the target mode of the target device in the air quality monitoring system. Each comparison result is used to indicate the operating level of the target device in the air quality monitoring system, and the operating level and the target mode have a one-to-one correspondence. After determining the target mode of the target device, the target device can be operated in the target mode to purify the air inside the vehicle. The target device may include, for example, an air purifier and / or a fresh air system.

[0073] S404. Determine that the fresh air system in the air quality monitoring system is running at a low speed (mode) and that the air purifier is turned off, i.e., the air purifier is in standby mode.

[0074] S405. Determine whether the concentration of carbon dioxide in the in-vehicle gas concentration is higher than the second preset concentration.

[0075] If the present application determines that the carbon dioxide concentration inside the vehicle is lower than the second preset concentration, it may continue to execute step S406; otherwise, it may continue to execute step S414.

[0076] S406. Determine whether the concentration of carbon dioxide inside the vehicle is higher than the concentration of carbon dioxide outside the vehicle.

[0077] If the present application determines that the carbon dioxide concentration inside the vehicle is higher than the carbon dioxide concentration outside the vehicle, it may continue to execute step S404; otherwise, it shall continue to execute step S414.

[0078] S407. Determine whether the oxygen concentration in the in-vehicle gas concentration is lower than the third preset concentration.

[0079] If the oxygen concentration inside the vehicle is determined to be lower than the third preset concentration, this application may continue to execute step S408; otherwise, it shall execute step S412.

[0080] S408. Determine whether the oxygen concentration inside the vehicle is lower than the oxygen concentration outside the vehicle.

[0081] If the application determines that the oxygen concentration inside the vehicle is lower than the oxygen concentration outside the vehicle, it may continue to execute step S409; otherwise, it shall continue to execute step S414.

[0082] S409. Determine whether the internal and external temperature difference is lower than the second preset temperature. The second preset temperature is lower than the first preset temperature, for example, the first preset temperature is 7°C and the second preset temperature is 3°C, etc.

[0083] If the application determines that the internal and external temperatures are lower than the second preset temperature, it may continue to execute step S410; otherwise, it shall continue to execute step S411.

[0084] S410. Set the fresh air system to high-speed (mode) operation and turn off the air purifier.

[0085] S411. Determine that the fresh air system is running at medium speed (mode) and turn off the air purifier.

[0086] S412. Determine whether the concentration of carbon dioxide in the in-vehicle gas concentration is higher than the fourth preset concentration.

[0087] If the present application determines that the carbon dioxide concentration inside the vehicle is lower than the fourth preset concentration, it may continue to execute step S413; otherwise, it may continue to execute step S414.

[0088] S413. Determine whether the concentration of carbon dioxide inside the vehicle is higher than the concentration of carbon dioxide outside the vehicle.

[0089] If the present application determines that the carbon dioxide concentration inside the vehicle is higher than the carbon dioxide concentration outside the vehicle, it may continue to execute step S409; otherwise, it shall continue to execute step S414.

[0090] S414. Determine the pollution level of each of the m other gas concentrations, and select the highest pollution level from the m pollution levels.

[0091] S415. Based on the maximum pollution level, determine the operating level of the air purifier and shut down the fresh air system. This application uses the concentrations of m other gases, including CH2O, CO, VOCs, and PM2.5, as examples. The order in which the pollution levels of each other gas concentration are determined is not limited in this application.

[0092] Specifically, this application can determine the pollution level of each other gas concentration based on the air quality parameters S0, S1, and S2 in Table 1 above. When the concentration of another gas is less than S0, the pollution level M = 0 can be determined. When the concentration of another gas is in the S0-S1 range, the pollution level M = 1 can be determined. When the concentration of another gas is in the S1-S2 range, the pollution level M = 2 can be determined. When the concentration of another gas is greater than S2, the pollution level M = 3 can be determined.

[0093] For example, please see Figure 5 A schematic flowchart illustrating a possible method for determining the operating mode of a target device is shown. Figure 5 This application exemplarily provides a method for sequentially determining the pollution levels of CH2O, CO, VOC, and PM2.5 concentrations, and selecting the highest pollution level from these levels. When the highest pollution level M = 0, this application determines that the fresh air system and air purifier are turned off; that is, the fresh air system and air purifier are both in standby mode. When the highest pollution level M = 1, this application determines that the fresh air system is turned off, and the air purifier operates at a low speed. When the highest pollution level M = 2, this application determines that the fresh air system is turned off, and the air purifier operates at a medium speed. Otherwise, this application determines that the fresh air system is turned off, and the air purifier operates at a high speed.

[0094] In optional embodiments, this application can also control the ventilation function of the ventilation fan to be turned on or off. Specifically, when it is determined that the oxygen concentration inside the vehicle is lower than the oxygen concentration outside the vehicle, this application can control the ventilation fan to be turned on for ventilation. And / or, when it is determined that the carbon dioxide concentration inside the vehicle is higher than the carbon dioxide concentration outside the vehicle, this application can turn on the ventilation fan for ventilation. In other words, when it is determined that the concentration of any one or both of the gases, oxygen and carbon dioxide, is lower than a preset threshold, and the air quality inside the vehicle is worse than the air quality outside the vehicle, this application can turn on the ventilation fan and the fresh air system for ventilation.

[0095] By implementing the embodiments of this application, this application acquires the in-vehicle temperature and in-vehicle gas concentration collected by the in-vehicle sensor group, and the outside temperature and outside gas concentration collected by the outside sensor group; determines the temperature difference between the inside and outside of the vehicle based on the in-vehicle temperature and the outside temperature; and controls the target device in the air quality monitoring system to operate under the corresponding target mode based on the temperature difference between the inside and outside of the vehicle and the gas concentrations inside and outside of the vehicle, so as to purify the air inside the vehicle. In the above solution, this application can control the target device in the air quality monitoring system to operate under the corresponding target mode based on the temperature difference between the inside and outside of the vehicle and the gas concentrations inside and outside of the vehicle, so as to achieve the purpose of monitoring and purifying the air quality inside the vehicle, thereby realizing rapid and efficient monitoring of the air inside the vehicle, which is beneficial to improving the user experience.
