Abstract

The air quality monitoring alarm recommendation system, method and computer device of the present invention can provide a travel decision based on the air quality and people's health status, and a list of things to prepare when traveling. In view of the fact that the air quality in streets changes rapidly and that some areas cannot be monitored when vehicles monitor the air quality during route navigation, when monitoring the air quality, the air quality collection unit on the building is preferentially used for preliminary air quality monitoring, and then the data is transmitted to the user. The user plans multiple navigation routes based on the data in combination with the GPS navigation module. The system also includes a mobile air quality precision monitoring component, which can monitor the air quality in real time on the driving route. It includes an air particle rapid detector and several air purifiers. The air quality can be preferentially detected by the air particle rapid detector. When the air quality does not meet the standard, several air purifiers are started for air purification.

Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to an air quality monitoring alarm suggestion system, method and computer device. Background Art

[0002] With the development of modern heavy industry, a large amount of waste gas and smoke are discharged into the atmosphere, and the air quality has further deteriorated. Home fresh air systems have also developed accordingly. However, there is no good alarm and recommendation system for the air quality when people are traveling, and people travel wherever they want. In the prior art, in response to increasingly severe air pollution, Patent Document 1 (CN11047313A) discloses an air quality-based vehicle navigation method and navigation system. The method includes an acquisition module, a route generation module, and a processing module. The route generation module generates a driving route based on an air quality map and vehicle location information. The vehicle navigation system uses data obtained by a vehicle equipped with an air quality sensor to provide an air quality map. The air quality sensor detects air quality and activates an air purifier when air quality is poor. If the air quality exceeds the purifier's purification capacity, the vehicle navigation system replans the route. Although the route is planned according to the air quality map, the air quality map is detected by a terminal installed on the vehicle. To obtain the air quality map, a vehicle must pass through. If no vehicles are on the navigation route, the air quality map may not be generated. Furthermore, the air quality sensor installed on the vehicle is highly sensitive to PM2.5 or PM10 in the air, which can cause significant fluctuations in air quality data during navigation. Air quality sensors installed on high-rise buildings can roughly detect PM2.5.5 or PM10, and the value will be relatively stable. In this way, when generating an air quality map, the route planning can be carried out by giving priority to the roughly measured air quality data, and then after passing a specific street, the on-board air quality detector can be used for accurate detection. This can avoid the problem of no vehicles on the navigation route and the problem of large changes in navigation data over time. The air purifier disclosed in Patent Document 1 cannot purify the air in large quantities, and thus the navigation data needs to be regenerated, which undoubtedly increases people's travel costs. In addition, it does not disclose an air quality detector that can adapt to rapid changes in the environment. Further, as disclosed in Patent Document 2 (CN1133 10862A) discloses a device and method for continuous detection of air particles based on Raman spectroscopy, which passes the air to be detected through a jet nozzle and then impacts it on the surface of a collection block, and then collects Raman spectra through the particles irradiated with laser, and feeds back to a computer to obtain the composition and concentration of the particles. The composition and concentration of the particles in the air can be obtained quickly, but since the impact surfaces of the collection block are adjacent, the air ejected from the jet nozzle may overflow to other impact surfaces, and there is also a problem of inaccurate detection results; for example, Patent Document 3 (CN111693420A) discloses an automatic monitoring and collection device for atmospheric particulate matter, which has a A ball cover is installed, and multiple layers of filter membranes are set inside the ball cover, and the diameter of the filter membranes gradually becomes smaller. The air to be monitored is introduced by the guide fan, and then filtered through the filter membrane. After filtering, the filter membrane is rotated to dissolve the particles in the air in the analysis liquid 111 for further analysis. Although it can monitor and collect air particles, it does not take into account the problem that large particles will block the filter membrane when the particles pass through the filter membrane, and the small particles behind cannot pass through the filter membrane, so that the particles of corresponding sizes are not completely separated during filtration. Moreover, when analyzing the analysis liquid, all particles are dissolved in the analysis liquid together, and it cannot be targeted. A detailed analysis of the composition of different particles is conducted; finally, Patent Document 4 (CN115581979A) discloses an air purifier with large-particle dust filtration. The filter is configured with a conical structure. This allows large dust particles and debris to slide more easily along the inclined surface into the annular groove, effectively ensuring the self-cleaning properties of the filter surface. This reduces the risk of clogging of the filter surface during long-term operation, which can lead to a decrease in air purification efficiency. While this filter configuration is highly practical, it only causes particles to accumulate toward the edges. Once accumulated at the edges, particles cannot continue to be filtered, resulting in incomplete particle filtration.

[0003] To sum up, in the prior art, for air quality monitoring, there is no system that can provide a list of alarms that people can leave the house or wear masks according to their age, physical health and current air quality index when the user goes out. Moreover, when performing route planning, it is not possible to give priority to preliminary navigation route planning based on the air detectors installed on the building, and then perform air quality monitoring based on the air detectors on the vehicle. There is also no system that can quickly and massively purify the air when air purification is needed. For this reason, the present invention provides an air quality monitoring alarm recommendation system, method and computer device that can make recommendations to users based on air quality data when traveling, and can perform air purification according to the air quality conditions when performing real-time route navigation.

[0012] Furthermore, an air quality monitoring alarm suggestion method is also provided, comprising the following steps:

[0013] 1. Preparation before traveling:

[0014] After collecting air quality data, the building air quality collection unit transmits it to an air quality data server. The data in the air quality data server is available to users through a web service interface. When traveling, the air quality data server transmits the collected air quality data to an air quality processing module for processing. The air quality processing module is connected to a GPS navigation module. The GPS navigation module is used to plan multiple navigation routes based on the departure point, destination, and map information. The air quality processing module downloads air quality data for each navigation route based on the multiple navigation routes and then transmits the time and air quality data of all navigation routes to a route planning module. The route planning module transmits all data to a display module. The display module includes the driving route, air conditions, basic information, and a checklist. The air conditions correspond to the driving route. After the user selects a navigation route as the driving route, the air conditions corresponding to the selected driving route are displayed. The basic information is the user's age or physical health status. The checklist then outputs corresponding recommended information based on the basic information, driving route, and air conditions. In the event of severe air pollution, the display module outputs an alarm signal, so that the checklist lists a warning reminder that it is not advisable to go out.

[0015] 2. Air quality monitoring when traveling:

[0016] When the user moves according to the driving route selected by the user, the mobile air quality precision monitoring component is started. Initially, the multi-way valve connects the air inlet with the air particulate rapid detector, and the air quality is measured after the air enters the air particulate rapid detector. When the air quality is excellent or good, there is no need to start the air purifier. When the air quality is lightly, moderately or heavily polluted, the multi-way valve is actuated to connect the air inlet with the several air purifiers, and the air enters the air purifier for deep purification.

[0017] 3. Deep air purification:

[0018] After the air first enters the air purification pipe of an air purifier, it passes through the first filter assembly, the second filter assembly and the third filter assembly at the air purification station in sequence, and at the same time, the rotating motors 1 and 2 of the first filter assembly and the second filter assembly are started, so that the rotating filter group can rotate relative to the outer cylinder 1, and at the same time, the rotating filter group can ensure close contact with the inner elastic deformation ring on the inner side of the outer cylinder 1; the air is filtered by the first filter assembly, the second filter assembly and the third filter assembly and then discharged from the exhaust pipe 2 for the user to breathe. After the preset time, when all the particles in the air have been filtered out, the multi-way valve is controlled to operate so that the air inlet of the multi-way valve is connected to another air purifier, and the air is purified through the other air purifier. The air filter replacement assembly in the original air purifier rotates and moves to the weighing loading station. The weighing assembly on the particle weighing system moves to the bottom of the filter assembly. The magnetic ring part 2 on the first filter assembly and the second filter assembly and the magnetic ring part 3 under the third filter assembly are electrified to generate magnetism, which attracts the magnetic ring part 1 on the weighing assembly, so that the weighing assembly The components are separated from the outer conveyor belt group and the inner conveyor belt group, and then the rotating motor 1 and the rotary drive motor B are driven to rotate, so that the particles on the rotating filter group and the fixed filter are poured into the inner loading hemispherical shell, and the weight of the particles is measured by the weighing device. The air filter replacement component continues to rotate. After the weighing component rotates to the weighing unloading station, the magnetic ring component 2 and the magnetic ring component 3 lose power and lose magnetism, and the weighing component falls onto the outer conveyor belt group and the inner conveyor belt group, so that the magnetic component 3 is energized and attracts the magnetic component 4 of the flip drive component, thereby driving the weighing component through the rotation of the drive motor. The weighing assembly rotates, and the air particles inside it fall into the corresponding analytical liquid tanks 1, 2 and 3; after the particles are dumped out, the magnetic suction component 3 loses power, and the outer conveyor belt group and the inner conveyor belt group drive the weighing assembly to move; the air filter replacement assembly continues to rotate, and after reaching the filter cleaning station, the filter assembly is cleaned by the nozzle, and the air filter replacement assembly continues to rotate, and the filter assembly returns to the air purification station, and then the multi-way valve is activated to disconnect the air inlet from the other air purifier and connect it to the original air purifier.

[0019] A computer device includes a processor, a memory and a display module, wherein the memory includes a computer program capable of implementing an air quality monitoring alarm suggestion method, and the processor executes the computer program.

[0020] The beneficial effects of the present invention are:

[0021] 1) The air quality monitoring and alarm recommendation system of the present invention can provide a travel decision based on the air quality and people's health conditions, and a list of things to prepare when traveling. In addition, it takes into account the fact that the air quality in streets changes rapidly, and the problem that some areas cannot be monitored when vehicles monitor the air quality during route navigation, when monitoring the air quality, the air quality collection unit installed on the building is preferentially used to perform preliminary air quality monitoring, and then the data is transmitted to the user, so that the user can plan multiple navigation routes based on the data in combination with the GPS navigation module. The user can select a route based on the air quality on the multiple navigation routes. After selecting the route, during the specific driving process, a mobile air quality precision monitoring component is also included. Through the setting of the mobile air quality precision monitoring component, the air quality can be monitored in real time on the driving route. The component includes an air particulate rapid detector and several air purifiers. The air quality can be preferentially detected by the air particulate rapid detector. When the air quality does not meet the standard, the several air purifiers are started to purify the air.

[0022] 2) The square collection block of the rapid air particle detector of the present invention is surrounded by a collection plate that is driven by a telescopic member to perform a telescopic movement. The lateral dimensions of the collection plate are consistent with the end of the jet nozzle. This prevents air from overflowing when it enters the jet nozzle and hits the collection plate, thereby ensuring the accuracy of air particle detection. At the same time, a collection plate receiving groove of the same size as the collection plate is provided at the bottom of the closed box. Therefore, when the surface of the collection plate is cleaned, air particles will not diffuse into the detection space. Compared with existing detectors, this can make air particle detection more accurate.

[0023] 3) Furthermore, the air purifier of the present invention includes a first filter group, a second filter group and a third filter group. The first filter group and the second filter group include a rotatable rotating filter group. The rotating filter group consists of a main filter and a sliding filter 1 and a sliding filter 2. When the rotating filter group rotates, the air particles filtered by it can be moved, thereby avoiding the situation where too large air particles clog the filter and small air particles cannot pass through the filter. At the same time, while rotating, the edge of the rotating filter group can always fit the inner elastic deformation ring on the inner side of the outer cylinder 1, thereby ensuring the filtering effect. At the same time, the main filter and the sliding filter 1, the main filter and the sliding filter 2 that move relative to each other can also drive the air particles thereon to move, further reducing the blockage of air particles. At the same time, it also includes a nozzle 1 and a nozzle 2 that can spray air in the opposite direction to blow out the particles blocking the filter. The nozzle 1 and the nozzle 2 can be activated when the filter is seriously clogged. In order to prevent air particles from being ejected by the nozzle 1 and the nozzle 2, a filter with the same mesh size as the main filter can also be provided at one end of the overflow channel.

[0024] 4) Furthermore, the air purifier of the present invention includes an air purification station, a weighing and loading station, a weighing and unloading station and a filter cleaning station. The rotating air filter replacement assembly drives the filter assembly to move along each station, and air filtration is performed at the air purification station. At the weighing and loading station, the weighing assembly is respectively installed under the first filter group, the second filter group and the third filter group. By driving the rotating filter group and the fixed filter to rotate, air particles are poured into the weighing assembly and the weight of the air particles is detected. Combined with the air volume measured by the air flow meter set in the air inlet or the distribution pipe, the PM2.5 or PM10 content is obtained, so that the air quality can be measured. At the weighing and unloading station, the weighing assembly can be unloaded again, and the air particles in the weighing assembly are respectively poured into the corresponding analysis liquid tank 1, analysis liquid tank 2 and analysis liquid tank 3, and air of different particle sizes is further detected. Finally, each filter is cleaned after entering the filter cleaning station, thus completing one cycle.

[0025] 5) Furthermore, in the present invention, an air purifier completes air purification at an air purification station, enters the next station, and starts another air purifier before completing a cycle. In this way, the operation of multiple air purifiers can make the overall air purification process uninterrupted, and it can achieve efficient air purification while also obtaining air quality data. At the same time, three particle weighing systems are set at the weighing loading station and the weighing unloading station. The three particle weighing systems are arranged vertically, and their positions can correspond to the first filter group, the second filter group, and the third filter group. The particle weighing system includes an inner conveyor belt group and an outer conveyor belt group, and several weighing components arranged thereon. The weighing components are transported by means of a conveyor belt. At the same time, the vertical transportation of the weighing components can be realized by the setting of the electromagnet. Combined with the horizontal transportation of the conveyor belt, the position conversion of the weighing component between the filter component and the conveyor belt group is realized, thereby realizing the measurement of air particle quality and the accurate and precise measurement of different air particles poured into the analysis liquid.

[0026] 6) Finally, the present invention also provides a computer device in which the environmental alarm system software used is constructed using the Java programming language and is open source; anyone with Java installed on their computer system can configure it, enabling them to modify the program code so that the alarm system can be redirected to obtain air quality data for different regions around the world, while enabling fast and accurate route navigation and rapid air purification when the air quality is poor.

DETAILED DESCRIPTION

[0043] The present invention is further described below with reference to the embodiments, but the present invention is not limited in any way. Any changes or substitutions made based on the teachings of the present invention fall within the scope of protection of the present invention.

[0044] An air quality monitoring alarm and suggestion system, such as Figure 1-13 As shown, it includes: several building air quality collection units installed on the building, such as Figure 1As shown in FIG, after the building air quality collection unit collects the air quality data, it is transmitted to the air quality data server through the data transmission unit and then through the wireless network. The data in the air quality data server is made available to users through the web service interface, so that users can know the outdoor air quality before traveling. When they need to go out, Figure 2 As shown, the air quality data server passes the collected air quality data to the air quality processing module for processing. The air quality processing module is connected to the GPS navigation module. The GPS navigation module is used to plan multiple navigation routes according to the departure place, destination and map information. The air quality processing module downloads the air quality data of each navigation route according to the multiple navigation routes, and then passes the time, air quality data and other data of all navigation routes (including highway fee data if there is a highway) to the section planning module. The section planning module passes all the data to the display module. The display module includes the driving route, air conditions, basic conditions and a list. The air conditions correspond to the driving route. When the user selects the route, the air quality data is displayed. After the route is used as the driving route, the air conditions will indicate the air quality of the selected driving route. The basic situation is the user's own input of age or physical health status, and then the list will output corresponding information based on the basic situation, driving route and air conditions. For example, if the selected driving route is long, the air quality is poor (such as when the PM2.5 concentration exceeds the preset value and reaches mild or moderate pollution), and the age is 20 and healthy, the user's list when traveling can only include masks. Of course, other recommended data can also be displayed in the list based on other input data. Even in the case of severe air pollution, older age, and physical discomfort, the display module outputs an alarm signal, so that the list will list a reminder that it is not suitable to go out.

[0045] Further, such as Figure 3-13As shown, in order to be able to accurately and quickly detect the air quality of the navigation route when the user is traveling, and to quickly purify the air when the air quality is poor, a mobile air quality precision monitoring component is also included, and the mobile air quality precision monitoring component includes an air inlet 1, a multi-way valve 2, an air particle rapid detector 3 and several air purifiers 4, the upper end of the multi-way valve 2 is connected to the air inlet 1, the side end is connected to the several air purifiers 4, and the lower end is connected to the air particle rapid detector 3, the multi-way valve 2 can select the air inlet 1 to be connected to the several air purifiers 4, or The user chooses to connect the air inlet 1 with the air particle rapid detector 3. When the user moves according to the driving route, the multi-way valve 2 connects the air inlet 1 with the air particle rapid detector 3. After the air enters the air particle rapid detector 3, the air quality can be measured. When the air quality is slightly polluted, such as when PM2.5 or PM10 is less than a certain threshold, it means that the outdoor air is good and there is no need to start the air purifier 4.

A magnetic ring 1 44 is provided at the top of the outer supporting hemispherical shell 40. A sealing soft film 43 is provided between the outer supporting hemispherical shell 40 and the inner loading hemispherical shell 41 to prevent dust or particles from entering between the inner loading hemispherical shell 41 and the outer supporting hemispherical shell 40.

[0053] Furthermore, a magnetic ring part 2 47 is provided at the lower end of the outer cylinder 1 22, a magnetic ring part 3 80 is provided at the lower end of the outer cylinder 2 81, and at the weighing and unloading station 11, an analytical liquid tank 1 19 is provided at the lower end of the first filter assembly 16, an analytical liquid tank 2 20 is provided at the lower end of the second filter assembly 17, and an analytical liquid tank 3 21 is provided at the lower end of the third filter assembly 18.

The receiving semicircular grooves 67 are used to receive the supporting rotating shaft one 45 and the supporting rotating shaft two 46. After the weighing assembly 35 falls onto the outer conveying belt group 33 and the inner conveying belt group 34, the magnetic part four 52 and the magnetic part three 48 attract each other, and when the driving motor 50 drives the rotating shaft 51 to rotate, the outer supporting hemispherical shell 40 is driven to rotate around the supporting rotating shaft one 45 and the supporting rotating shaft two 46, and the particles in the inner loading hemispherical shell 41 are poured into the corresponding analysis liquid tank one 19, analysis liquid tank two 20 and analysis liquid tank three 21, so that the components of the particles can be further analyzed.

[0054] Furthermore, the magnetic ring component 2 47, the magnetic ring component 3 80 and the magnetic ring component 3 48 are electromagnet structures, which generate magnetism when energized and disappear when the power is off. In this way, when the filter assembly 15 passes through the weighing and loading station 10, the magnetic ring component 2 47 and the magnetic ring component 3 80 are energized to generate magnetic force to attract the magnetic ring component 1 44, so that the weighing assembly 35 is adsorbed under the outer cylinder body 1 22 and the outer cylinder body 2 81. By driving the rotation of the rotating motor 1 and the rotating drive motor B, the rotating filter group 24 and the fixed filter 82 are driven to rotate, and the filtered particles thereon slide into the inner loading hemispherical shell 41. The weight of the particles is read by the weighing device 42, and then the flow rate or volume of the air flowing through is calculated by setting a flow meter at the air inlet 1, and finally the concentrations of PM2.5 and PM10 are calculated.

[0055] Furthermore, when the filter assembly 15 passes through the weighing and unloading station 11, the electromagnetic force of the magnetic ring component 2 47 and the magnetic ring component 3 80 disappears, and the weighing assembly 35 falls downward due to the influence of gravity, and the supporting rotating shaft 1 45 and the supporting rotating shaft 2 46 are both stuck in the receiving semicircular groove 67.

[0056] Furthermore, the rotation of the power wheel 1 36 and the power wheel 2 37 drives the circulating belt 39 to rotate, so that the weighing component 35 moves from the weighing unloading station 11 to the weighing loading station 10. During the movement, a cleaning device such as an air jet can be set to clean the remaining air particles in the weighing component 35, so that the weighing component 35 can remain clean after arriving at the weighing loading station 10, thereby ensuring the accuracy of the weighing.

[0057] Furthermore, cleaning tools such as air jets or liquid spray nozzles can also be set at the filter cleaning station 12, which can be aimed at the filter assembly 15, and then cooperate with the rotation of the driving rotation motor 1 and the rotation drive motor B of the filter assembly 15 to enable the filter to be cleaned in all directions. A drying mechanism can also be set between the air purification station 9 and the filter cleaning station 12, such as a hair dryer, to dry the liquid remaining on the filter, so that the filter assembly 15 can arrive at the air purification station 9 again for air purification.

[0058] Furthermore, the air purification duct 6 includes an upper pipe section 71, a middle pipe section 1 72, a middle pipe section 2 73 and a lower pipe section 74.

[0059] Furthermore, an overflow channel 75 is provided on the side of the upper pipe section 71 away from the air filter replacement assembly 7, and a nozzle 78 is provided at the side wall of the middle pipe section 72. The overflow channel 75 and the nozzle 78 are connected by a ventilation pipe 76. A nozzle 2 79 is provided on the side wall of the middle pipe section 2 73.

When the air pressure in the upper pipe section 71 rises to a certain pressure due to the blockage of the filter assembly 15, the overflow valve opens, and air is ejected from the nozzle 1 78 and the nozzle 2 79, thereby clearing the clogged filter and allowing the particles on the filter to be rearranged, thereby increasing the filtering effect of the filter.

[0060] Furthermore, an air intake port 53 is provided at the upper end of the outer box body 5, and an air outlet pipe 70 is provided at the lower end of the outer box body 5.

[0061] Furthermore, the number of the air purifiers 4 can be two or more. In this way, when the air purifier 4 is being weighed and cleaned, the other air purifiers 4 can continue to perform the air purification operation. This allows the air purification operation to be uninterrupted, thereby providing the user with a large amount of fresh, high-quality air.

[0062] Further, if Figure 1 and 13 As shown, the air particulate rapid detector 3 includes a closed box 54, a jet nozzle 55, an optical fiber probe 56 and an optical lens (not shown), wherein the jet nozzle 55 is fixedly arranged at the upper end of the closed box 54, the optical fiber probe 56 is fixedly arranged at the left end of the closed box 54, and the optical lens is fixedly arranged at the rear end of the closed box 54.

[0063] Furthermore, a dust cleaning channel 66 is provided at the lower end of the dust cleaning chamber 65 , and an air outlet pipe 57 is provided at the lower end of the dust cleaning channel 66 .

[0064] Furthermore, one end of the fiber optic probe 56 is connected to a laser and a spectrometer. The optical spectrometer is a Raman spectrometer.

After analysis, the spectrometer transmits the data to the processor to obtain particulate matter data.

[0065] Furthermore, the mobile air quality precision monitoring component can be detachably mounted on a car, wheelchair, or electric vehicle. When mounted on a car, the air in the second air outlet pipe 70 is discharged into the vehicle compartment. When mounted on a wheelchair or electric vehicle, the component also includes a helmet or a mask, which is connected to the second air outlet pipe 70 so that the purified air can flow into the helmet or mask, ensuring that the person can breathe fresh air that meets the standards while traveling.

[0066] Furthermore, the building air quality collection unit may choose to use the air particle rapid detector 3 to monitor the air quality.

[0067] Furthermore, after the air purifier 4 has been working for a period of purification, or the multi-way valve 2 is regularly operated to connect to the air particulate rapid detector 3 during a preset time period, after the air particulate rapid detector 3 detects that the air quality is excellent or good, the air purifier 4 is turned off to avoid wasting electricity; or the air purifier 4 can be turned off when the air quality detected in the initial navigation route is excellent.

[0068] Furthermore, the multi-way valve 2 can also be replaced by the following structure: the intake pipe 68, the jet nozzle 55 and the several distribution pipes 69 are all connected, and then electromagnetic opening and closing valves are set in the intake pipe 68, the jet nozzle 55 and the several distribution pipes 69. By controlling the opening or closing of each electromagnetic opening and closing valve, the air entering the air particulate matter rapid detector 3 or the air purifier 4, or the air intake sequence and action of each air purifier 4 are realized.

[0069] Furthermore, the rotation of the rotation support rod 13 can be achieved by providing a rotation motor at one end of the rotation support rod 13 , and the rotation of the rotation support rod 13 is achieved by the rotation of the rotation motor.

[0071] Furthermore, the upper pipe section 71, the middle pipe section 1 72, the middle pipe section 2 73 and the lower pipe section 74 are all fixedly arranged on the side wall of the outer box body 5; preferably, the fixation can be achieved by means of a fixing rod or a fixing frame.

[0072] Furthermore, the particle weighing system 8 can be arranged in the outer cylinder 5 to ensure that the working environment of the weighing component 35 is clean.

[0073] Furthermore, when air enters from the jet nozzle 55 for injection, the collection plate 62 of the telescopic collection plate group 60 located at the upper end of the square collection block 59 is pushed upward to the bottom end of the jet nozzle 55, thereby preventing air particles from overflowing when being injected into the collection plate 62. In addition, when the air particles on the collection plate 62 need to be cleaned, the collection plate 62 to be cleaned is rotated to the lower end, and then the telescopic part 61 is extended so that the collection plate 62 extends into the collection plate receiving groove 63, and then the cleaning roller 64 is driven by a motor to rotate, and the air particles on the collection plate 62 are swept into the cleaning chamber 65 and discharged from the cleaning channel 66. This arrangement can prevent air particles from diffusing in the working space of the closed box 54, interfering with the detection accuracy, and improving the detection accuracy.

[0074] Furthermore, a suction pump may be provided in the dust cleaning channel 66 to facilitate the discharge of air particles swept from the dust cleaning chamber 65 .

[0075] Furthermore, an air quality monitoring alarm suggestion method is also included, which includes the following steps:

[0076] 1. Preparation before traveling:

[0077] After the building air quality collection unit installed on the building collects air quality data, it is transmitted to the air quality data server. The data in the air quality data server is available for users to view through the web service interface. When it is necessary to go out, the air quality data server transmits the collected air quality data to the air quality processing module for processing. The air quality processing module is connected to the GPS navigation module. The GPS navigation module is used to plan multiple navigation routes according to the departure place, destination and map information. The air quality processing module downloads the air quality data of each navigation route according to the multiple navigation routes, and then stores the time, air quality data and other data of all navigation routes (if there is a The data of the route, air quality and air quality are transmitted to the display module, and the display module transmits all the data to the display module. The display module includes the driving route, air conditions, basic conditions and a checklist. The air conditions correspond to the driving route. After the user selects the navigation path as the driving route, the air conditions will indicate the air quality of the selected driving route. The basic conditions are the user's own input of age or physical health status. The checklist then outputs corresponding suggestion information based on the basic conditions, driving route and air conditions. In the case of severe air pollution, old age or physical discomfort, the display module outputs an alarm signal, so that the checklist lists an alarm reminder that it is not suitable to go out.

[0078] 2. Air quality monitoring when traveling:

[0079] When the user moves according to the driving route selected by the user, the mobile air quality precision monitoring component is started, which includes an air inlet 1, a multi-way valve 2, an air particle rapid detector 3 and several air purifiers 4. The upper end of the multi-way valve 2 is connected to the air inlet 1, the side end is connected to the several air purifiers 4, and the lower end is connected to the air particle rapid detector 3. The multi-way valve 2 can select the air inlet 1 to be connected to the several air purifiers 4, or select the air inlet 1 to be connected to the air particle rapid detector 3. Initially, the multi-way valve 2 connects the air inlet 1 to the air particle rapid detector 3. After the air enters the air particle rapid detector 3, the air quality is measured. When the air quality is excellent or good, such as when PM2.5 or PM10 is less than a certain threshold, it means that the outdoor air is good and there is no need to start the air purifier 4. When the air quality is lightly, moderately or heavily polluted, the multi-way valve 2 is actuated to connect the air inlet 1 to the several air purifiers 4, and the air enters the air purifier 4 for deep purification.

[0080] 3. Deep air purification:

[0081] After the air first enters the air purification duct 6 of the air purifier 4, it passes through the first filter assembly 16, the second filter assembly 17 and the third filter assembly 18 at the air purification station 9 in sequence, and the rotating motor 1 and the rotating motor 2 of the first filter assembly 16 and the second filter assembly 17 are started at the same time, so that the rotating filter group 24 can rotate relative to the outer cylinder 1 22, and at the same time, the rotating filter group 24 can ensure close contact with the inner elastic deformation ring 23 on the inner side of the outer cylinder 1 22; the air is filtered by the first filter assembly 16, the second filter assembly 17 and the third filter assembly 18 and then discharged from the exhaust pipe 2 70 for the user to breathe. After the preset time, when all the particles in the air are filtered, the multi-way valve 2 is controlled to operate so that the multi-way valve 2 The air inlet 1 of the through valve 2 is connected to another air purifier 4, and the air is purified through the other air purifier 4, while the air filter replacement component 7 in the original air purifier 4 rotates. After moving to the weighing loading station 10, the weighing component 35 on the particle weighing system 8 moves to the bottom of the filter component 15, and the magnetic ring component 2 47 under the first filter component 16 and the second filter component 17 and the magnetic ring component 3 80 under the third filter component 18 are energized to generate magnetism, and the magnetic ring component 1 44 on the weighing component 35 is attracted, so that the weighing component 35 is separated from the outer conveyor belt group 33 and the inner conveyor belt group 34, and then the rotating motor 1 and the rotary drive motor B are driven to rotate, so that the particles on the rotating filter group 24 and the fixed filter 82 are poured into the inner filter. Inside the hemispherical shell 41, the weight of the particles is measured by the weighing device 42, and the content of particulate matter in the air, such as PM2.5 and PM10, is finally calculated. The air filter replacement assembly 7 continues to rotate. After the weighing assembly 35 rotates to the weighing and unloading station 11, the magnetic ring component 2 47 and the magnetic ring component 3 80 lose power and magnetism, and the weighing assembly 35 falls onto the outer conveyor belt group 33 and the inner conveyor belt group 34, so that the magnetic component 3 48 is energized and attracts the magnetic component 4 52 of the flip drive component 49, thereby driving the weighing assembly 35 to rotate through the rotation of the drive motor 50, and the air particles therein fall into the corresponding analysis liquid tank 1 19, analysis liquid tank 2 20 and analysis liquid tank 3 21, and the components in the air particles are further detected. Compared with putting particles of different sizes into the analysis liquid together, more accurate results can be obtained, which is more conducive to air quality analysis; after the particles are dumped out, the magnetic component 3 48 loses power, and the outer conveyor belt group 33 and the inner conveyor belt group 34 drive the weighing component 35 to move; the air filter replacement component 7 continues to rotate, and after reaching the filter cleaning station 12, the filter component 15 is cleaned by the nozzle, and the air filter replacement component 7 continues to rotate, and the filter component 15 returns to the air purification station 9, and then the multi-way valve 2 is actuated to disconnect the air inlet 1 from the other air purifier 4 and connect the original air purifier 4. The action of the other air purifier 4 is the same as that of the original air purifier 4, which will not be repeated here.

[0082] Furthermore, the air quality can be positioned as excellent when the concentration of PM2.5 or PM10 is ≤35ug / cubic meter; good when the concentration is 35ug / cubic meter < ≤75ug / cubic meter; light pollution when the concentration is 75ug / cubic meter < ≤115ug / cubic meter; moderate pollution when the concentration is 115ug / cubic meter < ≤150ug / cubic meter; heavy pollution when the concentration is 150ug / cubic meter < ≤250ug / cubic meter; and severe pollution when the concentration is ≥250ug / cubic meter.

[0083] Furthermore, the present invention also provides a computer device, which includes a processor, a memory and a display module, wherein the memory includes a computer program capable of implementing the air quality monitoring alarm recommendation method, and the processor executes the computer program.

[0084] Furthermore, the computer program is constructed using the Java programming language and will be open source; it can be configured by anyone with Java installed on their computer system, enabling them to modify the program code to redirect the alert advisory system to obtain air quality data for different regions around the world.
