[0062] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0063] Refer to Figures 1a to 1d, the air quality monitoring device of the present application includes a device body 10, an indication module 20, and a controller 30; the indication module 20 includes an indication board assembly, the indication board assembly includes a driving member 22 and a plurality of indication boards 21 connected to the outer periphery of the driving member 22, each of the indication boards 21 has a different identifier to indicate different air quality states, the driving member 22 is used to drive the indication boards 21 to move, so that one of the indication boards 21 is exposed outside the device body 10, and the remaining indication boards 21 are hidden inside the device body 10. Among them, the controller 30 is electrically connected to the indication module 20, and the controller 30 is configured to: obtain data corresponding to at least one air quality index; determine the air quality state based on the data corresponding to at least one of the air quality indexes; according to the air quality state, control the driving member 22 to drive the indication boards 21 to move, so that the indication board 21 corresponding to the identifier of the air quality state is exposed outside the device body 10.

[0064] Among them, different indication boards 21 have different identifiers for indicating different air quality states, and different identifiers include different colors and / or patterns. For example, referring to Figure 2a , three indication boards 21 of different colors, namely red, yellow, and green, can be set to indicate three states of abnormal, good, and excellent air quality respectively. Of course, three different symbols, such as √, ○, and ×, can also be set on the indication board 21 to represent different air quality states, or different expressions can be used. For example, three different expressions, such as smiling, helpless, and sad, can be used to represent three different air quality states respectively. Of course, the identifiers of the indication boards 21 are not limited to the above examples. The indication boards 21 with different identifiers are used to indicate different air quality states, which are more intuitive and eye-catching for users. Or the identifier of the indication board 21 can also include a combination of color and expression, or the identifier of the indication board 21 can also adopt different shapes, such as circular, triangular, square, etc.

[0065] In some embodiments, there can also be four indication boards 21, which are respectively used to represent abnormal, general, good, and excellent air quality. Of course, the number of indication boards 21 can also be two or more than four, and according to the number of indication boards 21, more states of air quality can be represented respectively.

[0066] In some embodiments, referring to Figure 2b , a plurality of indication boards 21 are connected to the outer periphery of the driving member 22 in an annular array, and the device body 10 includes an open bin 12, and the driving member 22 is arranged in the open bin 12, so that one of the plurality of indication boards 21 can be exposed outside the open bin 12, and the remaining indication boards 21 are hidden in the open bin.

[0067] Of course, the driving member 22 can also be configured to drive the sign 21 to move up and down. For example, for lifting, one of the signs 21 can be raised while the other signs 21 are lowered according to the air quality status to be indicated.

[0068] In some specific embodiments, referring to Figure 1d , the device body 10 includes a housing 11. The housing 11 includes a rear cover 111, side covers 112, and a front cover 113, which together enclose a substantially enclosed three-dimensional space. The open bin 12 is provided on the back of the device body 10. One side is integrally formed with the back of the housing 11, and the other side is open and closed by the rear cover 111. An open strip-shaped opening is formed at the top of the open bin 12 for the sign 21 to enter and exit the open bin 12. Among them, the rear cover 111 and the housing 11 can be detachably connected by snap fasteners or bolts, so as to facilitate subsequent maintenance and replacement of the driving member 22 and the sign 21.

[0069] Among them, the spatial shape and size of the open bin 12 can allow the sign 21 to rotate therein. The open bin 12 can be set as a semicircle, and the radius of the semicircle is slightly larger than the rotation radius of the sign 21. It can be understood that the shape and size of the open bin 12 are determined according to the number and interval angle of the signs 21, so that only one sign 21 can be exposed at the same time. For example, if there are 4 signs 21 with an interval of 90°, the open bin 12 can be set as a 3 / 4 circle.

[0070] In some embodiments, a battery compartment 15 is further formed on the housing 11 for installing a storage battery.

[0071] In one embodiment, referring to Figure 1c , the sign assembly further includes a motor 23. The output shaft of the motor 23 is connected to the driving member 22, and the controller 30 is electrically connected to the motor 23 for controlling the driving member 22 to rotate. The controller 30 determines the air quality status according to the data collected by the sensor module 14, and controls the motor 23 to rotate according to the air quality status so that the corresponding sign 21 is exposed. Among them, the output shaft of the motor 23 can be connected to the driving member 22 to drive the driving member 22 to rotate.

[0072] In some embodiments, a cavity 132 is formed inside the device body 10, and a plurality of sensor modules 14 electrically connected to the controller 30 are arranged in the cavity 132. Each of the sensor modules 14 is respectively configured to collect and send data corresponding to different air quality indicators to the controller 30. The device body of the present application integrates various sensors such as a CO sensor, a formaldehyde sensor, a CO2 sensor, a TVOC sensor, a dust sensor, and a temperature and humidity sensor, which are respectively used to monitor carbon monoxide data, formaldehyde data, carbon dioxide data, total volatile organic compound index data, dust index data, temperature and humidity index data, etc. Of course, it is not limited to the above sensors here, and other air quality-related sensors can also be included, such as a radon gas sensor, etc., or at least one of the above sensors, which is not limited here.

[0073] In one embodiment, an air inlet 131 is formed on the surface of the device body 10. The air inlet 131 is communicated with the cavity 132 to form an air inlet passage 13. A display screen 24 is suspended at the air inlet 131, and the display screen 24 is electrically connected to the controller 30. Current air quality monitoring devices need to open a sufficient number and area of openings on the appearance surface to ensure smooth intake of the air inlet passage 13, thereby ensuring the accuracy of the monitoring by the sensor module 14. This will affect the aesthetics of the device. In the present application, a display screen 24 is suspended at the air inlet 131, and the air inlet 131 is hidden by the display screen 24, ensuring a sufficient intake area and ensuring the accuracy of the sensor module 14. From a design perspective, the aesthetics and performance are balanced.

[0074] Reference Figure 1c , a cavity 132 is formed between the side shell 112 and the front cover 113. The cavity 132 is communicated with the air inlet 131 and the air outlet 133 to jointly form the air inlet passage 13. The sensor module 14 and the controller 30 are both arranged in the cavity 132. The side shell 112 and the front cover 113 can be detachably connected by buckles or bolts, so as to facilitate subsequent maintenance and replacement of the sensor module 14 and the controller 30. The cavity 132 is communicated with the outside world, and is used for the sensor module 14 to monitor the external air quality indicators, and at the same time, it can facilitate the heat dissipation of the controller 30.

[0075] In one embodiment, the display screen 24 is an e-ink screen. The e-ink screen is more power-saving compared to the liquid crystal display screen 24 commonly used in current air quality monitoring devices. Although the e-ink screen does not display colors as vividly as the liquid crystal display screen 24, in the present application, sufficiently eye-catching indicator signs 21 have been used to indicate the air quality status. Therefore, the requirements for the types and vividness of the colors of the display screen 24 are not high, and the e-ink screen can be only used to display specific data.

[0076] Of course, in some embodiments, different colors or background colors may be used to display certain data to distinguish different data according to the comparison result between certain data and the preset data range, and different colors with different eye-catching degrees may be further used to indicate different air quality states. For example, if certain data is within the data range corresponding to the abnormal air quality state, the data is displayed with a red background color, if certain data is within the data range corresponding to the good air quality state, the data is displayed with a gray background color, and if certain data is within the data range corresponding to the excellent air quality state, the data is displayed with a white background color.

[0077] It should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0078] The following is a description from the perspective of air quality indication method, combined with Figures 3a to 3c As shown, Figure 3a A first flow chart of the air quality indication method provided in an embodiment of the present application.

[0079] 101. Obtain data corresponding to at least one air quality indicator;

[0080] 102. Determine an air quality state based on data corresponding to at least one of the air quality indicators;

[0081] 103. According to the air quality status, control the driving member to drive the indicator sign to move, so that the indicator sign corresponding to the air quality status is exposed outside the device body.

[0082] Among them, air quality indicators mainly include fine particulate matter (PM2.5), inhalable particulate matter (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), carbon monoxide (CO), total volatile organic compounds (TVOC), radon (Rn), etc. Data corresponding to at least one of the indicators can be obtained, such as one, two, three, four, five, six, seven, eight, nine, or more air quality indicators can be obtained. Different air quality indicators can be detected by different sensors.

[0083] Among them, this application can use a variety of sensor modules to collect data corresponding to different air quality indicators. In some embodiments, data corresponding to air quality indicators can also be obtained from the Internet or other smart home devices by connecting the device to the Internet or a smart home system.

[0084] Among them, steps 102 and 103 are described in detail in the following embodiments and will not be elaborated here.

[0085] As Figure 3b shown, Figure 3b FIG. 2 is a second flowchart of the air quality indication method provided by the embodiment of the present application. Among them, "102. Compare the data corresponding to each air quality indicator with the preset data range corresponding to each indicator respectively to determine the air quality status" may include:

[0086] 1021. If at least one of the data corresponding to each air quality indicator is within the first preset data range, determine that the air quality status is the first status;

[0087] 1022. If none of the data corresponding to each air quality indicator is within the first preset data range and at least one of the data is within the second preset data range, determine that the air quality status is the second status;

[0088] 1023. If none of the data corresponding to each air quality indicator is within the first data range and the second preset data range, and at least one of the data is within the third preset data range, determine that the air quality status is the third status.

[0089] Among them, the first preset data range, the second preset data range, and the third preset data range do not contain each other.

[0090] Among them, taking the air quality status being divided into three types: excellent (i.e., the third status), good (i.e., the second status), and poor (the first status) as an example for explanation, the first preset data range is the data range of poor air quality, the second preset data range is the data range of good air quality. If at least one data is within the data range of poor air quality, the air quality status is poor. If no data is within the abnormal data range and at least one data is within the data range of good air quality, the air quality status is abnormal. If no data is within the data range of poor air quality and the data range of good air quality, the air quality status is excellent.

[0091] Among them, the first preset data range, the second preset data range, and the third preset data range do not contain each other. For some air pollutant indicators, the value of the first preset data range is higher than that of the second preset data range, and the value of the second preset data range is higher than that of the third preset data range. For some beneficial indicators, the value of the first preset data range is lower than that of the second preset data range, and the value of the second preset data range is lower than that of the third preset data range.

[0092] Among them, there are multiple air quality indicators, and the first preset data range and the second preset data range corresponding to each air quality indicator are also different. For example, the air quality indicators mainly include fine particulate matter (PM2.5), inhalable particulate matter (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), carbon monoxide (CO), total volatile organic compounds (TVOC), radon gas (Rn), etc. Data corresponding to at least one of the indicators can be obtained. In some embodiments, the preset first data range corresponding to fine particulate matter (PM2.5) is 100 ug / m 3 Above, the preset second data range is 51-100 ug / m 3 , and the corresponding preset first data range of inhalable particulate matter (PM10) is 150 ug / m 3 Above, the preset second data range is 50-150 ug / m 3 , and the preset first data range of sulfur dioxide (SO2) is 500 ug / m3 or more, and the preset second data range is 150-500 ug / m 3 . It can be understood that in this application, when comparing the data corresponding to each air quality indicator with the preset indicator data range, the data corresponding to the same indicator is compared. For example, fine particulate matter (PM2.5) is compared with the preset first data range and the preset second data range corresponding to fine particulate matter (PM2.5), and sulfur dioxide (SO2) is compared with the preset first data range and the preset second data range corresponding to sulfur dioxide (SO2).

[0093] In some embodiments, different air quality states can be more specifically distinguished. In addition to the three air quality states of excellent (i.e., the third state), good (i.e., the second state), and poor (the first state), there can also be more states such as the fourth state, the fifth state, and the sixth state. For example, in one embodiment, there are six states, corresponding to different air quality states such as excellent, good, light pollution, moderate pollution, heavy pollution, and severe pollution, and the corresponding preset data ranges are 6.

[0094] Of course, in other embodiments, the air quality state can also be divided into only the first state and the second state, corresponding to qualified and unqualified respectively. The corresponding preset data ranges are two.

[0095] Such asFigure 3c As shown Figure 3c This is a schematic diagram of the second air quality indication method of the air quality monitoring device provided by the embodiment of the present application. Among them, "103. Control the driving member to rotate according to the air quality state and expose the corresponding sign of the sign outside the device body" may include:

[0096] 1031. Determine the previous sign exposed outside the device body at the previous monitoring moment;

[0097] 1032. Determine the current sign for indicating the air quality state at the current monitoring moment according to the air quality state;

[0098] 1033. Determine the rotation direction and / or rotation angle of the driving member according to the setting direction and interval angle of the previous sign and the current sign on the outer circumference of the driving member;

[0099] 1034. Control the current sign to be exposed outside the device body based on the rotation direction and rotation angle of the driving member.

[0100] The monitoring period can be preset. Data is acquired once every certain monitoring period, and the moment of acquiring data is called the monitoring moment. For example, the monitoring period can be set to 1 hour, half an hour, 1 minute, 5 minutes, 3 hours, 5 hours, etc., one day, two days, etc. Of course, data can also be acquired in real time to monitor the air quality state in real time for a long time. Of course, data can also be acquired in real time, and the data acquired every certain monitoring period is averaged and compared with the preset data range.

[0101] Among them, each time the controller 30 controls the driving member to rotate, it can store the exposed current sign in the linear table. When the sign needs to be rotated next time, the latest element in the linear table is taken out as the previous sign, and then the current sign is rotated and exposed according to the previous sign, and the current sign is stored in the linear table.

[0102] In other embodiments, the controller 30 can also sense the position of the current sign through sensors (such as optical sensors, Hall sensors, etc.) and rotate the current sign to the opening of the opening bin.

[0103] The number of signs and the interval angle between two adjacent signs are not limited in the present application. For the convenience of control by the controller 30, generally, there are 3 signs in total, and the interval between two adjacent signs is 120°.

[0104] In other embodiments, the driving member 22 may be configured to drive the indicator 21 to rise and fall. For example, one of the indicator 21 may be raised and the other indicator 21 may be lowered according to the air quality state to be indicated. If the last monitoring moment corresponds to the indicator A and the current monitoring moment corresponds to the indicator B, the indicator A is lowered and the indicator B is raised. If the indicator corresponding to the last monitoring moment and the current monitoring moment is the same, the indicator will not be moved.

[0105] In some embodiments, the indicator module further comprises a display screen, which is electrically connected to the sensor module and is used to display data corresponding to different air quality indicators. The display screen can be used to display data collected by the sensor module.

[0106] Of course, in some embodiments, different colors or background colors may be used to display certain data to distinguish different data according to the comparison result between certain data and the preset data range, and different colors with different eye-catching degrees may be further used to indicate different air quality states. For example, if certain data is within the data range corresponding to the abnormal air quality state, the data is displayed with a red background color, if certain data is within the data range corresponding to the good air quality state, the data is displayed with a yellow background color, and if certain data is within the data range corresponding to the excellent air quality state, the data is displayed with a white background color.

[0107] In some specific embodiments, the display screen may be an ink screen. Compared with the LCD screen commonly used in current air quality monitoring equipment, the ink screen is more power-saving. Although the colors displayed by the ink screen are not as bright and eye-catching as those displayed by the LCD screen, the present application has used a sufficiently eye-catching sign to indicate the air quality status. Therefore, the type and brightness of the display color are not required. The ink screen can be used only to display specific data.

[0108] In some embodiments, the air quality index is multiple, and the multiple air quality indexes include multiple single air quality indexes and comprehensive air quality indexes. After "101, obtaining data corresponding to multiple air quality indexes", the air quality indication method further includes:

[0109] Determining a plurality of individual air quality indicators and a comprehensive air quality indicator, wherein the comprehensive air quality indicator includes a plurality of individual air quality indicators;

[0110] Determining, from the individual air quality indicators, an interfering individual air quality indicator that will interfere with the detection of the comprehensive air quality indicator;

[0111] According to the interference monomer index data corresponding to the interference monomer air quality index, the comprehensive index data corresponding to the comprehensive air quality index is corrected to obtain the corrected comprehensive index data.

[0112] Correspondingly, based on the data corresponding to at least one of the above air quality indicators, determining the air quality status includes:

[0113] Comparing the data of each individual indicator and the corrected comprehensive indicator data with the preset data ranges corresponding to each indicator respectively to determine the air quality status.

[0114] Among them, the individual indicator is an air quality measurement indicator corresponding to a substance in the air. For example, fine particulate matter (PM2.5), inhalable particulate matter (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), carbon monoxide (CO), formaldehyde (CH 2 O), radon gas (Rn), etc.

[0115] Among them, the comprehensive indicator includes multiple individual indicators. For example, the total volatile organic compounds indicator (Total Volatile Organic Compounds, abbreviated as TVOC). Generally, TVOC can include any volatile organic compounds participating in the photochemical reaction in the atmosphere except carbon monoxide, carbon dioxide, carbonic acid, metal carbides, carbonates, and ammonium carbonate. Another example is that volatile organic compounds (VOCs) do not refer to a specific pollutant, but a general term for a class of organic compounds with similar physical and chemical properties. Volatile organic compounds participate in the formation of ozone and secondary aerosols in the atmospheric environment and have an important impact on regional atmospheric ozone pollution and PM2.5 pollution.

[0116] Among them, the individual air quality that interferes is the individual air quality indicator that will interfere with the detection of the comprehensive air quality indicator. For example, when detecting the total volatile organic compounds indicator (TVOC), the gas-sensitive element in the sensor is also sensitive to carbon monoxide and formaldehyde, but carbon monoxide and formaldehyde are not included in the total volatile organic compounds indicator (TVOC). When detecting the total volatile organic compounds indicator, carbon monoxide and formaldehyde will cause interference, resulting in inaccurate detection of the total volatile organic compounds indicator. Similarly, volatile organic compounds (VOCs) do not include PM2.5 and ozone, but PM2.5 and ozone will interfere with the detection of volatile organic compounds (VOCs).

[0117] In some embodiments, a variety of sensors such as a CO sensor, a formaldehyde sensor, a CO2 sensor, a TVOC sensor, a dust sensor, and a temperature and humidity sensor are integrated in the device body of the present application, which are respectively used to monitor carbon monoxide index data, formaldehyde index data, carbon dioxide index data, total volatile organic compound index data, dust index data, temperature and humidity index data, etc. Of course, the sensors are not limited to the above-mentioned ones here, and other air quality-related sensors such as radon sensors can also be included.

[0118] The present application corrects the comprehensive index data according to the interference monomer index data, so as to improve the accuracy of monitoring the comprehensive index data and the anti-interference ability.

[0119] In some specific embodiments, correcting the comprehensive index data corresponding to the comprehensive air quality index according to the monomer index data corresponding to multiple monomer air quality indexes to obtain the corrected comprehensive index data includes the following steps:

[0120] Calculate the interference coefficient of carbon monoxide data and / or formaldehyde data on the total volatile organic compound index data;

[0121] According to the interference coefficient, correct the total volatile organic compound index data to obtain the corrected total volatile organic compound index data.

[0122] It can be understood that the method of correcting the comprehensive index data corresponding to the comprehensive air quality index according to the monomer index data corresponding to the monomer air quality index is not limited to the above method, and other feasible methods can also be adopted. For example, a large number of experiments can be carried out in advance, and according to a large amount of experimental data, a correction model for the interference of formaldehyde on TVOC detection can be established. Considering factors such as formaldehyde concentration, types and concentrations of other TVOC components, and detection environment (such as temperature, humidity), a model that can accurately correct formaldehyde interference is constructed through mathematical methods such as multiple regression analysis. In actual detection, the detected relevant parameters are input into the model to correct the TVOC detection result to improve the detection accuracy.

[0123] In some embodiments, a mathematical model of the influence of carbon monoxide on TVOC detection can also be established through a large number of experiments and data analysis. Considering the interference law of different concentrations of carbon monoxide, environmental factors (such as temperature, humidity), etc. on the TVOC detection signal, a correction model is constructed by using methods such as multiple regression analysis. In actual detection, according to the detected carbon monoxide concentration and environmental parameters, the TVOC detection result is corrected through the model.

[0124] In some embodiments, before detecting TVOC, the concentration of carbon monoxide in the environment and its corresponding signal value are detected first. Then, when detecting TVOC, the signal generated by carbon monoxide is deducted from the TVOC signal to obtain a more accurate TVOC signal.

[0125] In some embodiments, the influence relationship (such as mathematical model, interference coefficient, influence factor, etc.) of carbon monoxide data and formaldehyde data on the total volatile organic compound index data can be obtained through experimental analysis in advance, and then the total volatile organic compound index data can be corrected based on this influence relationship.

[0126] Among them, the total volatile organic compound index data is one of the more serious pollutants affecting indoor air quality. It refers to organic compounds with a saturated vapor pressure exceeding 133.32 Pa at room temperature, with a boiling point between 50°C and 250°C, and can exist in the air in the form of evaporation at normal temperature. Its toxicity, irritation, carcinogenicity, and special odor can affect the skin and mucous membranes and cause acute damage to the human body. Generally, TVOC refers to the sum of various organic compounds that can volatilize into gases at normal temperature, which includes various types of organic substances such as benzene, toluene, xylene, ethylbenzene, styrene, acetaldehyde, acrolein, etc. Outdoor TVOC can come from laser processing, fuel combustion, and transportation. Indoor TVOC can come from combustion products such as coal and natural gas, smoking, heating and cooking, smoke from laser engraving, laser cutting, etc., adhesives, coatings, paints, boards, wallpapers, etc. in building and decoration materials, furniture, household appliances, furniture, cleaners, and emissions from the human body itself.

[0127] Specifically, the present application monitors the carbon monoxide index data and formaldehyde index data, and corrects the relevant interference coefficient in the total volatile organic compound index data to achieve a more accurate monitoring accuracy of the total volatile organic compound index data (when there is carbon monoxide index data and formaldehyde index data, calculate the interference coefficient of the carbon monoxide index data and formaldehyde index data on the total volatile organic compound index data. For example, one unit of carbon monoxide will cause the total volatile organic compound index data to increase by 0.2 units, then subtract the interference coefficient, that is, subtract 0.2 units, from the total volatile organic compound index data to obtain the total volatile organic compound index data after removing the interference).

[0128] In some embodiments, the air quality indication method further includes the following steps:

[0129] When powered by a battery, turn off some of the multiple sensors and / or control at least one sensor to monitor air quality data at a first monitoring frequency;

[0130] When the plug-in component is powered, control multiple sensors to monitor air quality data at a second monitoring frequency, where the first monitoring frequency is less than the second monitoring frequency.

[0131] The power access status of the plug-in component can be obtained, and then the power supply mode of the air quality monitor can be determined. When powered by a battery, some of the multiple sensors can be turned off, such as sensors with power consumption greater than a preset threshold, and the unturned-off sensors can be controlled to operate at the first monitoring frequency, or all sensors can be controlled to operate at the first monitoring frequency to extend the battery life of the air quality monitor. When powered by plugging in, all sensors can be controlled to monitor at the second monitoring frequency to ensure the accuracy of monitoring.

[0132] In some embodiments, the controller 30 is electrically connected to the sensor module and is used to control the monitoring mode of the sensor module according to the power supply method. When powered by a battery, the sensor module can be controlled to monitor at the first monitoring frequency, and sensors for certain high-power consumption monitoring items (such as total volatile organic compound index data) can be turned off to reduce power consumption, thereby achieving a longer battery life (in some embodiments, low-power sensors can be selected for the sensors). When powered by plugging in, the second monitoring frequency can be used for monitoring, and sensors corresponding to more monitoring items can be turned on to improve the accuracy and real-time performance of monitoring. Among them, the first monitoring frequency is lower than the second monitoring frequency.

[0133] In some embodiments, the air quality monitoring device can be connected to the smart home system through a communication module. Refer to Figure 4 , Figure 4 This is a smart home system provided by an embodiment of the present application. The system includes a server 200, a router 201, an air quality monitoring device 202, a terminal device 203, etc. The server, the terminal device, and the air quality monitoring device are connected through a network, and the network includes network entities such as a router.

[0134] Among them, the server 200 includes a smart home server and can also include a cloud server. A wireless local area network can be established with the family as a unit through the router 201. Smart home devices including the air quality monitoring device 202, the terminal device 203, and at least one smart home central control 204 (smart home assistant) are all connected to the wireless local area network to achieve wireless communication. Of course, the cloud server can also be connected through other networks such as a 5G network, and the terminal device 203 and the smart home central control 204 can be connected through the cloud server.

[0135] Among them, the terminal device 203 can be a terminal device with communication and display functions such as a computer device, a tablet computer, a cellular phone, a media player, a mobile phone, a smart watch, a television, etc.

[0136] An application can be installed in the terminal device 203 for the user to control the air quality monitoring device 202. The user operates on the terminal device 203 and communicates with the air quality monitoring device 202 through a local network (LAN) or a cloud server, so as to control the air quality monitoring device 202, send data instructions to the air quality monitoring device 202 or receive data instructions sent by the air quality monitoring device 202. The smart home assistant and the application can interact with the air quality monitoring device 202 through the local LAN. When receiving a prompt of deteriorating air quality, the smart home assistant or the application can send out a prompt message and can also prompt which machine or which room has monitored abnormal indicators. Specifically, the smart home assistant and the application can receive information such as air quality status information and various air quality index data monitored sent by the air quality monitoring device 202 through the local LAN, and send control instructions such as turning on the power-saving mode or turning off the power-saving mode to the air quality monitoring device 202.

[0137] In some embodiments, the present application can also analyze the abnormal air quality index data, judge the reason for the abnormal air quality and give suggestions. The specific steps are as follows:

[0138] According to the air quality status, count the abnormal air quality indexes within a preset data range at the current monitoring moment;

[0139] Determine the reason for the abnormal air quality according to the abnormal air quality indexes, and obtain the abnormal mitigation solution corresponding to the reason for the abnormal air quality;

[0140] Generate suggestion information according to the abnormal mitigation solution, and output the suggestion information.

[0141] In the storage module of the device body or the smart home assistant, the reasons for the abnormality of each air quality index, the corresponding abnormal mitigation solutions, and their applicable conditions are associated and stored. According to the abnormal air quality indexes, the reasons for the air quality indexes can be analyzed.

[0142] For example, when the particulate matter index data and the total volatile organic compound index data increase, it can be analyzed that it may be caused by natural fires nearby. At this time, it is recommended that the user do not ventilate by opening windows. If it is analyzed that it is caused by normal smoking, then it is necessary to recommend that the user ventilate by opening windows. Or if it is found through analysis that laser processing causes the air quality to deteriorate, it can be recommended that the user ventilate by opening windows or turn on the purifier.

[0143] In some embodiments, the air quality monitoring device can communicate with other intelligent terminal devices (such as mobile phones, tablets, personal computers, smart watches, etc.) via a local area network or 5G, and specifically can send advice messages to users via text messages or application messages.

[0144] To better implement the above method, an embodiment of the present invention further provides an air quality indication device, which can be specifically integrated in the air quality monitoring device.

[0145] For example, in this embodiment, taking the air quality indication device integrated in the air quality monitoring device as an example, the method of the embodiment of the present invention will be described in detail.

[0146] For example, as Figure 5a shown, the air quality monitoring device may include an acquisition unit 301, a determination unit 302, and a driving unit 303. As follows:

[0147] (1) The acquisition unit 301 is used to acquire data corresponding to at least one air quality index.

[0148] (2) The determination unit 302 is used to determine the air quality status based on the data corresponding to at least one of the air quality indexes.

[0149] (3) The driving unit 303 is used to control the driving member to drive the sign to move according to the air quality status, so that the sign corresponding to the air quality status is exposed outside the device body.

[0150] In some embodiments, the determination unit 302 can specifically be used for the following steps: If at least one of the data corresponding to each of the air quality indexes is within the first preset data range, then determine that the air quality status is the first state; if none of the data corresponding to each of the air quality indexes is within the first preset data range, and at least one is within the second preset data range, then determine that the air quality status is the second state; if none of the data corresponding to each of the air quality indexes is within the first preset data range and the second preset range, and at least one of the data is within the third preset data range, then determine that the air quality status is the third state; where the first preset data range, the second preset data range, and the third preset data range do not contain each other.

[0151] In some embodiments, the driving unit 303 can be specifically configured to perform the following steps: determine the previous sign exposed outside the device body at the previous monitoring moment; determine the current sign for indicating the air quality state at the current monitoring moment according to the air quality state; determine the rotation direction and / or rotation angle of the driving member according to the setting direction and the interval angle of the previous sign and the current sign on the outer periphery of the driving member; and control the current sign to be exposed outside the device body based on the rotation direction and rotation angle of the driving member.

[0152] In some embodiments, there are multiple air quality indicators, and the multiple air quality indicators include multiple single air quality indicators and a comprehensive air quality indicator. The air quality detection device further includes a calibration unit, and the calibration unit can be specifically configured to: determine, from the multiple single air quality indicators, the interfering single air quality indicators that will interfere with the detection of the comprehensive air quality indicator; and calibrate the comprehensive indicator data corresponding to the comprehensive air quality indicator according to the interfering single indicator data corresponding to the interfering single air quality indicators to obtain the calibrated comprehensive indicator data.

[0153] In some embodiments, the air quality detection device further includes a suggestion unit, and the suggestion unit is configured to: count the abnormal air quality indicators within a preset data range at the current monitoring moment according to the air quality state; determine the cause of the abnormal air quality according to the abnormal air quality indicators, and obtain the abnormal mitigation plan corresponding to the cause of the abnormal air quality; generate suggestion information according to the abnormal mitigation plan, and output the suggestion information.

[0154] In summary, in the embodiment of the present application, the acquisition unit 301 is used to acquire data corresponding to at least one air quality indicator; the determination unit 302 is used to determine the air quality state based on the data corresponding to at least one air quality indicator; and the driving unit 303 is used to control the driving member to drive the sign to move according to the air quality state, so that the sign corresponding to the air quality state is exposed outside the device body. The present application indicates the air quality state through the sign. Whenever the air quality state changes, the sign assembly rotates and the sign corresponding to the identification is exposed, which can more simply and intuitively determine different air quality states without the user having to judge the current air quality indicator based on the indicator data, and is more convenient to use.
