Description

A kind of household air intelligent purification system and method

Technical Field

The present invention belongs to the technical field of air purification, and in particular relates to a household air intelligent purification system and method.

Background Art

In recent years, people's living standards have been continuously improved, and people pay more and more attention to the indoor living environment. However, with the development of science and technology, the current building materials have been gradually replaced by high-performance plastics and chemical products from the previous brick and wood structures. However, these decorative materials will volatilize a variety of harmful substances. In addition, the increase in the use of electrical appliances has reduced the number of negative oxygen ions in the room, which will lead to poor indoor air quality. The traditional way to improve indoor air quality is generally to open windows for ventilation and introduce outdoor air into the room. However, due to the current deepening of atmospheric pollution, the outdoor air quality is getting worse and worse. Opening windows for ventilation when the outdoor air quality is poor will undoubtedly aggravate indoor air pollution and affect people's living environment. In this case, air purification equipment that can purify indoor air quality has gradually come into people's sight. Air purification equipment filters and ventilates indoor air to achieve the purpose of purifying air.

However, the current purification method of air purification equipment is to place it in a fixed position indoors for purification. This fixed purification method has the following defects in the actual purification process: 1. At present, the purification process of indoor air by air purification equipment generally first detects indoor air pollution parameters by the detection part in the air purification equipment, and then performs purification according to the detection results. Since the current air purification equipment is fixed and cannot be moved, the air purification equipment can only directly detect the air pollution parameters around its placement location, and cannot directly detect the air pollution parameters in other areas of the room, resulting in a limited detection range.

2. The purification principle of fixed air purification equipment is to diffuse the filtered fresh air through the panel grille to the indoor location that needs to be purified. On the one hand, it requires a certain purification time, and the longer the indoor location that needs to be purified is from the location where the air purification equipment is placed, the longer the purification time is, and targeted purification cannot be achieved. This increases the power consumption for purification to a certain extent, resulting in low purification efficiency. On the other hand, it ignores the monitoring of the attachments on the panel grille. When there are attachments on the panel grille, such as dust, it is easy to blow the attached dust on the panel grille to the indoor location that needs to be purified during the blowing purification process through the panel grille, causing secondary air pollution and affecting the purification effect.

Summary of the invention

In order to overcome the above-mentioned shortcomings, the present invention proposes a household air intelligent purification system and method for mobile air purification equipment. By deploying air pollution detection terminals in indoor spaces, direct detection of indoor air pollution parameters in various indoor areas is achieved, and mobile air purification equipment is used to perform mobile targeted purification of indoor air according to the detection results. At the same time, panel grille attachment monitoring and alarm are performed in real time during the targeted purification process, which can effectively overcome the above-mentioned defects of current fixed air purification equipment.

The purification equipment panel grille automatic warning module is used to set a second camera device and a voice alarm on the panel grille of the mobile air purification equipment.

According to a preferred embodiment of the first aspect of the present invention, the current purification obstacle avoidance route planning unit is used to plan a purification obstacle avoidance route to the current purification point according to the positioning position of the current purification point and the current position of the mobile air purification equipment, and the specific planning method is as follows: H1: Project the current purification point on the ground to obtain the projected purification point of the current purification point on the ground, and obtain the positioning position of the projected purification point.

H2: A first camera device is provided on the mobile purification equipment to perform camera scanning at the location of the projection purification point to obtain a scanned image of the projection purification point area.

H3: Obstacle identification is performed on the scanned image of the projection purification point area, and the number of identified obstacles is counted, and the location of each obstacle is obtained at the same time.

H4: According to the current position of the mobile air purification device and the positioning position of the projected purification point, a straight line route from the current position of the mobile air purification device to the positioning position of the projected purification point is obtained, and it is determined whether the positions of the identified obstacles are located on the straight line route. If the positions of the identified obstacles are not located on the straight line route, then the straight line route is the purification obstacle avoidance route of the current purification point. Otherwise, the number of obstacles on the straight line route is counted. Thus, in the process of planning the purification obstacle avoidance route of the current purification point, the obstacles on the straight line route are avoided and planned to form a purification obstacle avoidance route of the current purification point after avoidance.

According to a preferred embodiment of the first aspect of the present invention, the following moving unit is used to follow the mobile air purification device to move to the positioning position of the projected purification point according to the planned purification and obstacle avoidance route.

R4: After the initial purification wind speed gear adjustment is completed, the current time point is recorded and used as the start purification time point. The purification stage time points are divided from the start purification time point according to the pre-set purification stage interval, and when reaching each purification stage time point, the air pollution parameter detection is performed again through the air pollution detection terminal of the current purification point, and then it is identified whether the air pollution parameters of the current purification point at each purification stage time point need to be purified. If it is identified that the air pollution parameters of the current purification point at a certain purification stage time point do not need to be purified, the mobile air purification equipment is automatically controlled to stop purification. Otherwise, the air pollution degree value of the current purification point at the purification stage time point is obtained through the air quality transmission module and the air quality analysis server, and it is processed according to the method of step R2 to obtain the purification wind speed representative coefficient of the current purification point at the purification stage time point.

R5: The purification wind speed representative coefficient of the current purification point at the time point of the purification stage is processed according to the method of step R3, so as to dynamically adjust the purification wind speed level of the current purification point at the time point of the purification stage.

A second aspect of the present invention provides a method for intelligent home air purification, comprising the following steps: A. arranging detection points in the indoor space to be air purified, and setting an air pollution detection terminal at each detection point to detect the air pollution parameters of each detection point in real time;

B. Analyze the air pollution parameters of each detection point to obtain the air pollution level value of each detection point;

E. During the dynamic processing operation of the purification process of the current purification point based on the mobile air purification equipment, the panel grille of the mobile air purification equipment is monitored for attachments. If the panel grille is monitored to have attachments at a certain moment, it is determined that an alarm should be issued at that moment. At this moment, the mobile air purification equipment is automatically controlled to stop purification and an alarm is issued;

F. After the current purification point is purified, the next round of analysis and screening of the current purification point, dynamic processing of the purification process of the next round of the current purification point and monitoring and alarm processing of attachments on the grille of the mobile air purification equipment panel are carried out.

Based on the above, the advantages of the present invention are: 1. The present invention arranges detection points in the indoor space to be air purified, and sets an air pollution detection terminal at each detection point to directly detect the air pollution parameters of each detection point in the room in real time. There is no need for air purification equipment to detect indoor air pollution parameters. On the one hand, it can expand the detection range of indoor air pollution parameters and avoid the problem that fixed air purification equipment can only directly detect air pollution parameters around the area where the air purification equipment is placed, resulting in a limited detection range. On the other hand, the air pollution detection terminal can perform real-time direct detection at the corresponding detection point position, which can greatly improve the accuracy of the detection results and provide a reliable purification basis for subsequent purification treatment.

2. The present invention identifies whether the air pollution parameters of each detection point need purification and analyzes the air pollution degree value, and selects the current purification point therefrom. The mobile air purification equipment then performs mobile targeted purification processing on the current purification point, thereby achieving targeted purification of indoor air and reflecting the flexibility of purification to a certain extent, thereby greatly avoiding the defect of the current fixed air purification equipment that cannot perform targeted purification. The targeted purification can effectively reduce the purification time, thereby not only improving the purification efficiency, but also reducing the purification power consumption, and has the advantage of convenient and fast purification.

3. The present invention monitors the panel grille of the mobile air purification equipment for attachments and automatically alarms. On the one hand, it greatly avoids the occurrence of air purification being hindered by the presence of sticky objects attached to the panel grille of the mobile air purification equipment, thereby improving the purification efficiency from the perspective of the purification main equipment; on the other hand, it effectively avoids the occurrence of secondary air pollution in the purification process of the indoor space caused by the presence of dust attached to the panel grille of the mobile air purification equipment, which is beneficial to improving the purification effect.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Please refer to Figure 1. The first aspect of the present invention provides a home air intelligent purification system, which requires a mobile air purification device. The system includes an air quality detection module, an air quality transmission module, an air quality analysis server, an intelligent purification processing terminal and an automatic early warning module for the purification device panel grille, wherein the air quality detection module is connected to the air quality analysis server through the air quality transmission module, the air quality analysis server is connected to the intelligent purification processing terminal, and the intelligent purification processing terminal is connected to the automatic early warning module for the purification device panel grille.

Specifically, it should be noted that the mobile air purification equipment mentioned in the present invention is movable, can be charged by battery for purification, is not limited by power cords, and is provided with a GPS locator, a first camera device and various purification wind speed gears, wherein various purification wind speed gears correspond to a purification wind speed representative coefficient range respectively, and a second camera device and a voice alarm are provided on the panel grille of the mobile air purification equipment.

The air quality detection module is used to arrange detection points in the indoor space to be air purified. The specific arrangement method is to arrange the detection points on the surrounding walls and roof of the indoor space according to the set layout positions, where the set layout positions can be corners, connection points between walls, etc., and each detection point is numbered, and the positioning position of each detection point is obtained at the same time, thereby setting an air pollution detection terminal at each detection point, where the air pollution detection terminal is a detection sensor corresponding to PM2.5 concentration, dust concentration, benzene concentration, formaldehyde concentration and carbon monoxide concentration, which is used to detect the air pollution parameters of each detection point in real time.

In some embodiments of the present invention, detection points are arranged in the indoor space to be air purified, and an air pollution detection terminal is set at each detection point to directly detect the air pollution parameters of each detection point in the room in real time. There is no need for air purification equipment to detect indoor air pollution parameters. On the one hand, the detection range of indoor air pollution parameters can be expanded to avoid the problem that fixed air purification equipment can only directly detect air pollution parameters around the area where the air purification equipment is placed, resulting in a limited detection range. On the other hand, real-time direct detection at the corresponding detection point by the air pollution detection terminal can greatly improve the accuracy of the detection results, providing a reliable purification basis for subsequent purification treatment.

The air quality transmission module is used to transmit the air pollution parameters of each detection point to the air quality analysis server, where the transmission method can be Bluetooth transmission or WiFi transmission.

The air quality analysis server is used to identify whether the air pollution parameters received at each detection point need to be purified. The specific identification steps are as follows: Step 1: Obtain the volume of the indoor space, and based on the predefined safety values of each air pollution parameter per unit space volume, multiply the safety value of each air pollution parameter per unit space volume by the indoor space volume to obtain the safety value of each air pollution parameter in the indoor space.

Step 2: Compare the air pollution parameters of each detection point with the safety value of each air pollution parameter in the indoor space. If an air pollution parameter of a detection point is greater than the safety value of the air pollution parameter in the indoor space, the detection point is identified as needing purification. Conversely, if all air pollution parameters of a detection point are less than or equal to the safety value of the air pollution parameter in the indoor space, the detection point is identified as not needing purification.

A detection point that needs to be purified is selected from each detection point, and the detection point is recorded as a purification detection point. At this time, the purification detection point number is recorded, and the number can be recorded as 1, 2, ..., i, ..., n.

In some embodiments of the present invention, the purpose of selecting purification detection points for each detection point is to improve the analysis effectiveness and efficiency for the subsequent air pollution level value analysis of the purification detection points, and to avoid the occurrence of invalid analysis of some detection points due to the air pollution level value analysis of all detection points.

The air pollution degree value of each purification detection point is analyzed, and the analysis process specifically includes the following steps:

S1: The air pollution parameters of each purification detection point constitute the purification detection point air pollution parameter set G _w = {g _w 1, g _w 2, .. . , g _w i... , g _w n} g _w i represents the air pollution parameter of the i-th purification detection point, w represents the air pollution parameter, w = r1, r2, r3, r4, r5, representing PM2.5 concentration, dust concentration, benzene concentration, formaldehyde concentration, and carbon monoxide concentration respectively.

表示为第i个净化检测点的空气污染程度值，g′_w表示为各空气污染参数在该室内空间的安全值，其中某净化检测点的空气污染参数数值大于该空气污染参数在该室内空间的安全值，则该净化检测点的空气污染程度值越大，从而表明空气污染程度越高。S2: Compare the air pollution parameter set of the purification detection point with the safety value of each air pollution parameter in the indoor space, and calculate the air pollution degree value of each purification detection point. The calculation formula is:

It is represented as the air pollution degree value of the ith purification detection point, _g′w is represented as the safety value of each air pollution parameter in the indoor space, and if the air pollution parameter value of a purification detection point is greater than the safety value of the air pollution parameter in the indoor space, the greater the air pollution degree value of the purification detection point is, indicating a higher air pollution degree.

Please refer to Figure 2. The intelligent purification processing terminal is used to perform current purification point analysis and screening, current purification process processing and current purification completion intelligent processing on the air pollution level values of each purification detection point. The intelligent purification processing terminal includes a current purification point analysis and screening module, a current purification process dynamic processing module and a current purification completion processing module.

The current purification point analysis and screening module is used to sort the purification detection points in descending order according to the air pollution degree value, and extract the purification detection point ranked first as the current purification point, and record the number of the current purification point.

It should be noted that selecting the current purification point from various purification detection points reflects the arrangement of the current purification order, and realizes the priority purification of the purification detection points with the highest air pollution level.

The current purification process dynamic processing module is used to obtain the positioning position of the current purification point according to the number of the current purification point, and obtain the current location of the mobile air purification device by setting a GPS locator in the mobile air purification device, so that the mobile air purification device moves to the current purification point according to the positioning position of the current purification point and the current location of the mobile air purification device to perform dynamic processing operations of the purification process, wherein the current purification process dynamic processing module includes a current purification obstacle avoidance route planning unit, a follow-up mobile unit, a purification distance acquisition unit and a purification process intelligent control unit.

The current purification obstacle avoidance route planning unit is used to plan the purification obstacle avoidance route to the current purification point according to the positioning position of the current purification point and the current position of the mobile air purification equipment. The specific planning method is as follows: H1: Project the current purification point on the ground to obtain the projected purification point of the current purification point on the ground, and obtain the positioning position of the projected purification point.

In some embodiments of the present invention, the current purification point is projected to obtain the purification point, which is convenient for the movement of the mobile air purification device on the ground. For some detection points, they are set at the corners of the wall. No matter how the mobile air purification device moves, it only moves on the ground and cannot reach the location of such detection points. Therefore, it is necessary to project the current purification point and use the location of the projected purification point as the moving end point target of the mobile air purification device.

H2: A first camera device is provided on the mobile purification equipment to perform camera scanning at the location of the projection purification point to obtain a scanned image of the projection purification point area.

H3: Obstacle identification is performed on the scanned image of the projection purification point area, and the number of identified obstacles is counted, and the location of each obstacle is obtained at the same time.

H4: According to the current position of the mobile air purification device and the positioning position of the projected purification point, a straight line route from the current position of the mobile air purification device to the positioning position of the projected purification point is obtained, and it is determined whether the positions of the identified obstacles are located on the straight line route. If the positions of the identified obstacles are not located on the straight line route, then the straight line route is the purification obstacle avoidance route of the current purification point. Otherwise, the number of obstacles on the straight line route is counted. Thus, in the process of planning the purification obstacle avoidance route of the current purification point, the obstacles on the straight line route are avoided. The specific avoidance method can be based on the size of the obstacle to plan the avoidance distance, so as to form a purification obstacle avoidance route for the current purification point after avoidance.

As another embodiment of the present invention, in the process of obtaining a straight line route from the current location of the mobile air purification device to the projected purification point positioning position, it is also necessary to identify whether there are obstacles at the projected purification point positioning position. If there are obstacles at the projected purification point positioning position, it is necessary to avoid the obstacle and select the point closest to the projected purification point positioning position and without obstacles as the moving end point of the mobile air purification device.

In some embodiments of the present invention, by planning a purification and obstacle avoidance route for the mobile air purification device to the current purification point, it is possible to effectively avoid the problem that the mobile air purification device cannot perform targeted purification of the current purification point due to encountering obstacles during movement. At the same time, it is also possible to speed up the time it takes for the mobile air purification device to reach the moving destination.

The following mobile unit is used to follow the mobile air purification equipment to move to the positioning position of the projected purification point according to the planned purification and obstacle avoidance route.

The purification distance acquisition unit is used to obtain the vertical distance between the projected purification point and the current purification point after the mobile air purification device moves to the positioning position of the projected purification point. The specific acquisition method can be to subtract the position coordinates of the current purification point from the position coordinates of the projected purification point to obtain the vertical distance between the projected purification point and the current purification point, and obtain the height of the mobile air purification device, and then subtract the vertical distance between the projected purification point and the current purification point from the height of the mobile air purification device to obtain the purification distance of the current purification point, which is recorded as l.

As another embodiment of the present invention, if there is an obstacle at the projection purification point positioning position, the purification distance of the current purification point can be obtained by obtaining the coordinates of the point position that is closest to the projection purification point positioning position and has no obstacles, and obtaining the height of the mobile air purification device, thereby obtaining the coordinates of the height of the purification device when the mobile air purification device is placed at the point according to the coordinates of the point, thereby obtaining the purification distance of the current purification point according to the coordinates of the height of the purification device and the position coordinates of the current purification point. For example, if the position coordinates of the current purification point are (x ₀ , y ₀ , z ₀ ), if the position coordinates of the point that is closest to the projection purification point positioning position and has no obstacles are (x, y, z), assuming that the height of the mobile air purification device is h, then the coordinates of the height of the purification device are (x, y, z+h), and the purification distance calculation formula of the current purification point is

The intelligent control unit of the purification process is used to perform intelligent purification control on the air at the current purification point. The specific control process is as follows: R1: According to the number of the current purification point, it can be recorded as k, k∈(1, 2, ..., i, ..., n), and the air pollution level value of the current purification point is extracted from the air pollution level values corresponding to each detection point, recorded as

得到当前净化点对应的净化风速代表系数，需要说明的是，本发明提到的净化风速代表系数代表的是净化风速，ξ表示为当前净化点对应的净化风速代表系数，

l₀分别表示为设定的参考空气污染程度值、参考净化距离，其中当前净化点的空气污染程度值和净化距离均与净化风速代表系数成正比例关系，表明空气污染程度值越大、净化距离越长，净化风速代表系数越大，表明需要的净化风速越大，其中空气污染程度值越大，净化风速越大的原因是空气污染程度值越大，需要有更大的净化风速去净化处理才能使当前净化点的空气污染程度值快速降低，其中净化距离越长，净化风速越大的原因是净化设备对应的每种净化风速都对应一定净化距离构成的净化区域，而净化距离越长，较小净化风速对应的净化区域可能就波及不到当前净化点所在位置，也就无法实现对当前净化点的针对性净化，这时就需要有更大的净化风速才能将过滤后的新鲜空气扩散到当前净化点所在位置。R2: Substitute the air pollution level and purification distance of the current purification point into the set purification wind speed representative coefficient calculation formula

The purification wind speed representative coefficient corresponding to the current purification point is obtained. It should be noted that the purification wind speed representative coefficient mentioned in the present invention represents the purification wind speed, and ξ is represented by the purification wind speed representative coefficient corresponding to the current purification point.

l ₀ represents the set reference air pollution level value and reference purification distance respectively, where the air pollution level value and purification distance of the current purification point are both in direct proportion to the purification wind speed representative coefficient, indicating that the greater the air pollution level value and the longer the purification distance, the greater the purification wind speed representative coefficient, indicating that the required purification wind speed is greater. The reason why the air pollution level value is greater and the purification wind speed is greater is that a greater purification wind speed is required for purification treatment in order to quickly reduce the air pollution level value of the current purification point. The reason why the purification distance is longer and the purification wind speed is greater is that each purification wind speed corresponding to the purification equipment corresponds to a purification area composed of a certain purification distance, and the longer the purification distance, the purification area corresponding to the smaller purification wind speed may not reach the current purification point, and the targeted purification of the current purification point cannot be achieved. At this time, a greater purification wind speed is required to diffuse the filtered fresh air to the current purification point.

R3: Match the purification wind speed representative coefficient of the current purification point with the purification wind speed representative coefficient range corresponding to various purification wind speed gears of the mobile air purification equipment. If the purification wind speed representative coefficient of the current purification point is within the purification wind speed representative coefficient range of a certain purification wind speed gear of the mobile air purification equipment, it indicates that the match is successful. At this time, the successfully matched purification wind speed gear is selected to open the panel grille of the mobile air purification equipment, and the initial purification wind speed gear of the mobile air purification equipment is intelligently adjusted to meet the successfully matched purification wind speed gear.

The present invention identifies whether the air pollution parameters of each detection point need purification and analyzes the air pollution degree value, and selects the current purification point therefrom, so that the mobile air purification equipment can perform mobile targeted purification processing on the current purification point, thereby realizing targeted purification of indoor air and embodying the flexibility of purification to a certain extent, thereby greatly avoiding the defect of the current fixed air purification equipment that cannot perform targeted purification. The targeted purification can effectively reduce the purification time, thereby not only improving the purification efficiency, but also reducing the purification power consumption, and has the advantage of convenient and fast purification.

R4: After the initial purification wind speed gear adjustment is completed, the current time point is recorded and used as the start purification time point. The purification stage time points are divided from the start purification time point according to the pre-set purification stage interval, and when reaching each purification stage time point, the air pollution parameter detection is performed again through the air pollution detection terminal of the current purification point, and then it is identified whether the air pollution parameters of the current purification point at each purification stage time point need to be purified. The identification method refers to the first and second steps. If it is identified that the air pollution parameters of the current purification point at a certain purification stage time point do not need to be purified, the mobile air purification equipment is automatically controlled to stop purification. Otherwise, the air pollution degree value of the current purification point at the purification stage time point is obtained through the air quality transmission module and the air quality analysis server, and it is processed according to the method of step R2 to obtain the purification wind speed representative coefficient of the current purification point at the purification stage time point.

R5: The purification wind speed representative coefficient of the current purification point at the time point of the purification stage is processed according to the method of step R3, so as to dynamically adjust the purification wind speed level of the current purification point at the time point of the purification stage.

In some embodiments of the present invention, automatic dynamic regulation of the purification wind speed level is performed during the purification process of the current purification point, which can save power resources while achieving the purification purpose and avoid the waste of power caused by always using a uniform purification wind speed level for purification during the purification process. This is because as the purification time goes by, the air pollution level value of the current purification point will decrease accordingly. If the initial purification wind speed level is used for purification, it will inevitably cause waste of purification power.

The current purification completion processing module is used to obtain the air pollution parameters of each detection point corresponding to the purification completion time point from the air quality detection module after the purification of the current purification point is completed, and then obtain the air pollution degree value of each detection point corresponding to the purification completion time point through the air quality transmission module and the air quality analysis server, so as to carry out the next round of analysis and screening of the current purification point and dynamic processing of the purification process.

The automatic warning module for the panel grille of the purification equipment is used to set a second camera device and a voice alarm on the panel grille of the mobile air purification equipment. When the panel grille of the mobile air purification equipment is opened to perform air purification at each round of the current purification point, the second camera device is used to monitor in real time whether there is attachment on the panel grille. The specific monitoring method is to collect the surface image of the panel grille in real time and compare it with the normal surface image of the panel grille to identify whether there is attachment, wherein the normal surface image of the panel grille refers to the surface image without attachment, and the attachment includes both attached dust and attached sticky matter. If the attachment is identified in the panel grille surface image collected at a certain moment, it is determined that an alarm should be issued at that moment. At this moment, the mobile air purification equipment is automatically controlled to stop purification, and the voice alarm is started to alarm to remind the indoor personnel to pay attention. At the same time, the position of the panel grille where the attachment is located is located and identified according to the panel grille surface image collected at that moment, and then the position of the panel grille where the attachment is located is voice broadcasted through the voice alarm, thereby providing a specific cleaning position for manual cleaning of the attachment, greatly facilitating the cleaning of the attachment and improving the cleaning efficiency.

It should be specifically noted that the location of the above-mentioned attachment can be identified by the column number of the panel grid where the attachment is located.

In some embodiments of the present invention, the panel grille of the mobile air purification device corresponds to the purification air outlet, which is generally a multi-row grille. When there is sticky matter attached to the panel grille, the blowing area of the purification air outlet will be affected. When there is dust attached to the panel grille, during the purification blowing process, the attached dust is very likely to be blown into the room, thereby causing secondary air pollution. Therefore, by monitoring the panel grille of the mobile air purification device for attachments and automatically alarming, on the one hand, it greatly avoids the occurrence of air purification being hindered by the presence of sticky matter attached to the panel grille of the mobile air purification device, thereby improving the purification efficiency from the perspective of the purification main equipment; on the other hand, it effectively avoids the occurrence of secondary air pollution in the purification process of the indoor space caused by the presence of dust attached to the panel grille of the mobile air purification device, thereby helping to improve the purification effect.

In some embodiments of the present invention, after the purification of the current purification point is completed, the purpose of directly performing the next round of analysis and screening of the current purification point instead of extracting the second-ranked purification detection point from the purification detection point corresponding to the current purification point as the next purification target is that the indoor air is constantly circulating, which leads to the air pollution parameters of each detection point in the room not being static. The purification of the current purification point requires a certain purification process, and during this purification process, it is very likely that the air pollution parameters of each detection point will change. If the arrangement order of the purification detection points corresponding to the current purification point continues to be used as a reference for the next purification target at this time, it does not conform to the actual situation and cannot purify the air of the detection points that actually need to be purified first.

In conjunction with FIG. 3 , based on the above design ideas, the second aspect of the present invention provides a method for intelligent home air purification, comprising the following steps: A. arranging detection points in the indoor space to be air purified, and setting an air pollution detection terminal at each detection point to detect the air pollution parameters of each detection point in real time;

B. Analyze the air pollution parameters of each detection point to obtain the air pollution level value of each detection point;

C. Sort the detection points in descending order according to the air pollution degree value, and extract the detection point ranked first as the current purification point;

D. Obtain the location of the current purification point, and obtain the current location of the mobile air purification device by setting a GPS locator in the mobile air purification device, so that the mobile air purification device moves to the current purification point according to the location of the current purification point and the current location of the mobile air purification device to perform dynamic processing operations during the purification process;

E. During the dynamic processing operation of the purification process of the current purification point based on the mobile air purification equipment, the panel grille of the mobile air purification equipment is monitored for attachments. If the panel grille is monitored to have attachments at a certain moment, it is determined that an alarm should be issued at that moment. At this moment, the mobile air purification equipment is automatically controlled to stop purification and an alarm is issued;

F. After the current purification point is purified, the next round of analysis and screening of the current purification point, dynamic processing of the purification process of the next round of the current purification point and monitoring and alarm processing of attachments on the grille of the mobile air purification equipment panel are carried out.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the invention or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.
