Description

Technical Field

[0001] This application relates to the field of air purification technology, and in particular to an air purification method, system, storage medium and air purifier. Background Technology

[0002] As air quality deteriorates, harmful components in the air become more damaging to the human body, and people are paying more and more attention to air pollution. Air purifiers can effectively purify indoor air pollution and improve the air quality of the home environment.

[0003] Among related technologies, the most commonly used air purifiers are filter-type air purifiers. They use an internal fan to draw in air containing particulate pollutants from the outside and filter it through an internal filter. The filtered air is then discharged from the outlet to achieve air purification.

[0004] Regarding the aforementioned technologies, during the use of air purifiers, the coverage area of ​​the purified air is limited. Generally, the relative position of the air purifier in the space is fixed, but the relative position of the user in the space may change, which may result in the user being in a position with poor air quality. Therefore, it is necessary to improve the air purification effect to improve the user experience. Summary of the Invention

[0005] To improve air purification efficiency and enhance user experience, this application provides an air purification method, system, storage medium, and air purifier.

[0006] In a first aspect, this application provides an air purification method, which adopts the following technical solution:

[0007] An air purification method, comprising:

[0008] Obtain the location of personnel and equipment in the area;

[0009] A variable virtual position of the equipment is established on the preset equipment movement track, and the required distance is determined by calculating the personnel position and the virtual position of the equipment in each area.

[0010] Based on a preset appropriate matching relationship, determine the appropriate local parameters corresponding to the required distance;

[0011] The comprehensive suitable parameters are determined by calculating based on all local suitable parameters at the virtual location of a single device.

[0012] The virtual location of the equipment with comprehensive suitable parameters greater than the preset benchmark requirement parameters is defined as the qualified placement location, and the required movement distance is determined based on the equipment's operating location and the qualified placement location.

[0013] The minimum required movement distance is determined according to a preset sorting rule, and the corresponding suitable placement location is defined as the required placement location. The air purifier is then controlled to move from its operating position to the required placement location to perform its operation. By adopting the above technical solution, the distribution of people in the area is acquired and analyzed during the use of the air purifier to determine a location for the air purifier to operate. This ensures that the air purified by the air purifier can better benefit the people in the area, improving both air purification efficiency and user experience.

[0014] Optionally, after the required travel distance is determined, the air purification method may also include:

[0015] Determine if there are at least two suitable placement locations with the same minimum required movement distance;

[0016] If there are no at least two qualified placement locations with the same minimum required movement distance, the placement location is determined based on the single smallest required movement distance.

[0017] If there are at least two qualified placement locations with the same and minimum required movement distance, the qualified placement location corresponding to the required movement distance is defined as the alternative placement location, and the location of each person in the area first obtained is defined as their initial location.

[0018] The location change trend is determined based on the initial location and the location of people in the area, and subsequent virtual points are established based on the location change trend, the location of people in the area, and the preset unit distance.

[0019] Determine the appropriate comprehensive parameters for a single alternative placement location based on the alternative placement locations and each subsequent virtual point;

[0020] Based on the sorting rules, determine the comprehensive suitable parameter with the largest value among the two candidate placement positions, and determine the candidate placement position corresponding to the comprehensive suitable parameter as the required placement position.

[0021] By adopting the above technical solution, when there are multiple qualified placement locations that meet the requirements, the possibility of subsequent personnel changes can be predicted, so that the selected required placement location can be easily adjusted for the subsequent placement of the air purifier.

[0022] Optionally, after the air purifier is moved to the desired location, the air purification method may also include:

[0023] Control the rotation of the built-in filter to switch the internal orientation and obtain the pollution level value of the air after purification at each external vent; determine the pollution ranking of each external vent based on the pollution level value under the built-in filter in the same internal orientation, and determine the purification ranking of the built-in filter based on the pollution level value obtained in the same external orientation.

[0024] After the built-in filter rotates one full turn, a variable virtual position is established in the position where the internal orientation of the built-in filter changes. In the virtual position, the deviation parameters between each internal filter and the external orientation are determined according to the external orientation pollution sorting and the internal filter purification sorting.

[0025] The error parameter is determined by calculating all the deviation parameters, and the error parameter with the smallest value is determined according to the sorting rules. The virtual position corresponding to the error parameter is defined as the appropriate working position, and the built-in filter is controlled to rotate to the appropriate working position to perform the operation.

[0026] By adopting the above technical solution, the pollution in the external environment and the filtration capacity of the filter can be analyzed before the air purifier operates, so as to adjust the position of the built-in filter and make the air purifier have a better overall purification effect on the air.

[0027] Optionally, after the error parameters are determined, the air purification method may also include:

[0028] Determine whether there exist at least two virtual positions with the same and smallest error parameters;

[0029] If there are no at least two virtual locations with the same and smallest error parameters, then the appropriate working location is determined based on the unique virtual location.

[0030] If there are at least two virtual positions with the same and smallest error parameters, the corresponding virtual position is defined as an optional position, and a fixed interval with a fixed duration and a preset width is established on the preset time axis with the current time point as the end point.

[0031] Within a fixed interval, a similar time period is defined based on the current time point, and the pollution source area corresponding to the internal orientation of the internal filter is determined based on the selectable location;

[0032] The population change trend in the pollution source area was obtained within a similar time period;

[0033] Within a single pollution source area, a representative trend is determined based on changes in the population size of the area, and the pollution ranking of external locations is corrected based on this representative trend.

[0034] The error parameters are recalculated and determined based on the updated external orientation pollution sorting, and the error parameter with the smallest value is determined according to the sorting rules. The corresponding optional location is then defined as the appropriate working location.

[0035] By adopting the above technical solution, when multiple virtual locations meet the requirements, the changes in pollution levels in each subsequent location are predicted, so that the location selected by the air purifier can effectively purify the air. Optionally, the step of determining the representative trend of change based on the population change area in a single pollution source area includes:

[0036] The trends in regional population changes are categorized into upward trends, stable trends, and downward trends.

[0037] The trend time period is determined by counting similar time periods corresponding to the population change trends in different regions, and the trend representativeness percentage of each different region's population change trend is determined based on all the trend time periods.

[0038] Within the pollution source areas, the regions are sorted from largest to smallest based on the trend representative proportion, and the difference between the trend representative proportions of the top two in the sort is calculated to determine the difference trend proportion.

[0039] Determine whether the percentage of the difference trend is greater than the preset demand percentage;

[0040] If the proportion of the difference trend is not greater than the proportion of demand, then the stable trend is determined to represent the changing trend.

[0041] If the proportion of the difference trend is greater than the proportion of demand, then the trend that appears first in the ranking will be determined as the representative trend.

[0042] By adopting the above technical solution, a more accurate representative trend can be determined based on the specific changing trends in each time period within a fixed interval.

[0043] Optionally, the steps for revising the external orientation pollution sorting based on representative change trends include:

[0044] Determine whether the trend representing change is a stable trend;

[0045] If the trend represents a stable trend, then maintain the original external orientation pollution sorting.

[0046] If the representative trend is not a stable trend, then the average value is calculated based on the population change trend in the corresponding region to determine the overall average value.

[0047] The correction parameters corresponding to the overall change mean are determined based on the preset correction matching relationship;

[0048] Based on the representative trend of change, the corresponding pollution degree values ​​in the external pollution ranking are calculated by difference to determine the ranking interval value;

[0049] Determine if the correction parameter is greater than the sorting interval value;

[0050] If the correction parameter is not greater than the sorting interval value, then the original external orientation contamination sorting is maintained.

[0051] If the correction parameter is greater than the sorting interval value, the external orientation corresponding to the sorting interval value will be sorted and swapped in the external orientation pollution sorting.

[0052] By adopting the above technical solution, the external orientation pollution ranking can be corrected more accurately.

[0053] Optionally, after the built-in filter is rotated to the appropriate operating position for operation, the air purification method may also include:

[0054] Determine whether the pollution level of the air purified by each air outlet is less than the preset permissible benchmark value;

[0055] If the pollution level of the air purified by each air outlet is less than the permissible benchmark value, then the built-in filter will be kept in its original state.

[0056] If the pollution level of the air purified by each air outlet is not less than the permissible benchmark value, a suitable working position will be re-determined from the remaining virtual positions according to the sorting rules, and the built-in filter will be rotated to adjust to the updated suitable working position.

[0057] By adopting the above technical solution, the purification status is monitored during the use of the air purifier, so that when the purification requirements cannot be met in some areas, the position of the built-in filter can be adjusted to meet the purification needs.

[0058] Secondly, this application provides an air purification system, which adopts the following technical solution:

[0059] An air purification system, comprising:

[0060] The acquisition module is used to acquire the location of personnel and the operating location of equipment in the area;

[0061] The processing module, connected to the acquisition and judgment modules, is used for information storage and processing;

[0062] The judgment module, connected to the acquisition and processing modules, is used for judging information.

[0063] The processing module establishes a variable virtual position of the equipment on the preset equipment movement track, and calculates the required distance based on the personnel position in each area and the virtual position of the equipment.

[0064] The processing module determines the appropriate local parameters corresponding to the required distances based on a preset suitable matching relationship;

[0065] The processing module calculates and determines the comprehensive appropriate parameters based on all suitable local parameters at a single virtual device location;

[0066] The processing module defines the virtual position of the equipment, which is determined by the judgment module to have a comprehensive suitable parameter greater than the preset benchmark requirement parameter, as a qualified placement position, and determines the required movement distance based on the equipment's operating position and the qualified placement position.

[0067] The processing module determines the minimum required movement distance according to the preset sorting rules, defines the qualified placement position corresponding to the required movement distance as the required placement position, and controls the air purifier to move from the equipment operation position to the required placement position to perform operation.

[0068] By adopting the above technical solution, during the use of the air purifier, the acquisition module acquires the distribution of people in the area and the processing module analyzes it to determine a location for the air purifier to operate. This allows the air purified by the air purifier to be better applied to the people in the area, improving the air purification effect and enhancing the user experience.

[0069] Thirdly, this application provides an air purifier, which adopts the following technical solution:

[0070] An air purifier includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and executed any of the above-described air purification methods.

[0071] By adopting the above technical solution, and through the use of an air purifier, the distribution of people in the area is acquired and analyzed during the use of the air purifier to determine a location for the air purifier to operate. This ensures that the air purified by the air purifier can better benefit the people in the area, improving both the air purification effect and the user experience. Fourthly, this application provides a computer storage medium capable of storing corresponding programs, which has the characteristics of improving air purification effect and enhancing user experience, and adopts the following technical solution:

[0072] A computer-readable storage medium storing a computer program that can be loaded by a processor and executed by any of the above-described air purification methods.

[0073] By adopting the above technical solution, the computer program containing the air purification method in the storage medium acquires and analyzes the distribution of people in the area during the use of the air purifier, and determines a location for the air purifier to operate. This allows the air purified by the air purifier to be better applied to the people in the area, improving the air purification effect and enhancing the user experience.

[0074] In summary, this application includes at least one of the following beneficial technical effects:

[0075] During the use of air purifiers, the position of the air purifier can be reasonably adjusted according to the distribution of people in the area to make the air purifier more effective in purifying the air and improve the user experience.

[0076] Before using an air purifier, the position of the built-in filter will be adjusted to further improve the air purification effect.

[0077] During the use of an air purifier, the filtration status in all directions is monitored. If some areas fail to meet the purification requirements, the position of the built-in filter can be adjusted to overcome this defect and improve the stability of the air purifier.

[0086] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-8The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0087] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0088] This application discloses an air purification method. When the air purifier is in use, the distribution of people in the area can be obtained and analyzed. The position of the air purifier can be adjusted according to the distribution of people. After the position of the air purifier is adjusted, the external pollution situation and the filtration capacity of the built-in filter can be known by rotating the built-in filter. Thus, the built-in filter can be adjusted to a suitable position so that the air purifier has a better air purification effect, and the air can be effectively purified to improve the user experience.

[0089] Reference Figure 1 The air purification method includes the following steps:

[0090] Step S100: Obtain the location of personnel and the location of equipment in the area.

[0091] The personnel location in the designated area refers to the location of personnel within the area where the air purifier operates. For example, if an air purifier is installed in a warehouse, the corresponding personnel location is the location of the personnel within the warehouse. This location can be obtained through camera capture or by installing RFID chips on the shoes worn by personnel entering the warehouse and placing chip reading devices on the warehouse floor. The specific method is set by the staff according to the actual situation. It should be noted that the corresponding personnel location is recorded only after a person has stood at a certain point for a certain period of time, not the actual location of the person at each location. The equipment operating location is the location of the air purifier, which can be obtained by installing a positioning device on the air purifier.

[0092] Step S101: Establish a variable virtual position of the equipment on the preset equipment movement track, and calculate the required distance based on the personnel position in each area and the virtual position of the equipment.

[0093] The equipment movement track is the track that allows the air purifier to move and stop. It is usually laid on the wall or ceiling to facilitate the movement of the air purifier. The virtual position of the equipment is a random location point on the equipment movement track. The required distance is the distance between the location of the people in the area and the virtual position of the equipment.

[0094] Step S102: Determine the appropriate local parameters corresponding to the required distance based on the preset appropriate matching relationship.

[0095] The local suitability parameter reflects the degree to which the air purifier can provide users with suitable purified air at the required distance. The larger the value, the better the air purifier can provide purified air to users at that required distance. The suitable matching relationship between the two is determined by the staff in advance.

[0096] Step S103: Calculate and determine the comprehensive suitable parameter based on all local suitable parameters at the virtual location of a single device. The comprehensive suitable parameter is the value obtained by summing all local suitable parameters and taking the average.

[0097] Step S104: Define the virtual position of the equipment with comprehensive suitable parameters greater than the preset benchmark requirement parameters as the qualified placement position, and determine the required movement distance based on the equipment operation position and the qualified placement position.

[0098] The baseline requirement parameters are the minimum comprehensive suitable parameters that must be met to achieve a good air purification effect for most users in the area. The qualified placement position is defined to distinguish different virtual positions of the equipment, which facilitates subsequent control of the air purifier. The required movement distance is the distance that the air purifier needs to move from the equipment operation position to the qualified placement position along the equipment movement track.

[0099] Step S105: Determine the minimum required moving distance according to the preset sorting rules, define the qualified placement position corresponding to the required moving distance as the required placement position, and control the air purifier to move from the equipment operation position to the required placement position to perform operation.

[0100] The sorting rules are methods set by staff to sort numerical values, such as the bubble sort method. By using the sorting rules, the minimum required movement distance can be determined. This means that the qualified placement position determined at this point is the most convenient for the air purifier to move. The required placement position is defined to distinguish between different qualified placement positions, thereby controlling the air purifier to move to the required placement position to perform its operation. This allows the air purifier to perform air purification operations better, and the users in the area will have a better experience.

[0101] Reference Figure 2 Once the required travel distance is determined, air purification methods also include:

[0102] Step S200: Determine whether there are at least two qualified placement locations with the same and minimum required movement distance.

[0103] The purpose of the judgment is to determine whether there are multiple qualified placement locations that meet the requirements, so as to determine whether the only qualified placement location needs to be screened.

[0104] Step S2001: If there are no at least two qualified placement locations with the same minimum required movement distance, then the required placement location is determined based on the unique minimum required movement distance.

[0105] When there are no at least two qualified placement locations with the same minimum required movement distance, it means that there is only one qualified placement location that meets the requirements. In this case, the required placement location can be determined based on the unique qualified placement location.

[0106] Step S2002: If there are at least two qualified placement locations with the same and smallest required movement distance, the qualified placement location corresponding to the required movement distance is defined as the alternative placement location, and the location of each person in the area first obtained is defined as their initial location.

[0107] When there are at least two qualified placement locations with the same and minimum required movement distance, it indicates that there are multiple qualified placement locations that meet the requirements, requiring further analysis. At this point, alternative placement locations are defined to distinguish between different qualified placement locations. The initial location is the location of the person currently in the area when they first enter the area. Step S201: Determine the location change trend based on the initial location and the location of the person in the area, and establish subsequent virtual points based on the location change trend, the location of the person in the area, and a preset unit distance.

[0108] The location change trend refers to the trend of the initial location pointing towards the location of the people in the area. This trend can simulate the location change trend of the user's walking. At this time, moving a unit distance along the location change trend from the location of the people in the area can generate the location point that the user may move to later. This location point is the subsequent virtual point, which is used to predict the user's subsequent location and facilitate the screening of candidate placement locations. The unit distance is a fixed distance set by the staff, which will not be elaborated further.

[0109] Step S202: Determine the appropriate comprehensive parameters for a single alternative placement location based on the alternative placement locations and each subsequent virtual point.

[0110] The required distance is calculated by replacing the location of personnel in the area in step S101 with a virtual point. Then, the comprehensive appropriate parameters can be calculated according to steps S102-S103.

[0111] Step S203: Determine the comprehensive suitable parameter with the largest value among the two candidate placement positions according to the sorting rules, and determine the candidate placement position corresponding to the comprehensive suitable parameter as the required placement position.

[0112] By using sorting rules, we can determine the most suitable comprehensive parameter. This means that when the air purifier is placed in the corresponding alternative location, it will have a better purification effect when the user moves the device. In this case, the alternative location is determined as the required location, which not only ensures that the air purifier can be used normally, but also facilitates the subsequent repositioning of the air purifier.

[0113] Reference Figure 3 After the air purifier is moved to the desired location, the air purification method also includes:

[0114] Step S300: Control the rotation of the built-in filter to switch the internal orientation and obtain the pollution level value of the air purified by the air vents in each external direction.

[0115] The built-in filter is installed inside the air purifier to filter the air. The filter is arranged circumferentially inside the air purifier to effectively filter air coming from all directions. Internal orientation switching means changing the direction the filter faces. For example, if the air purifier's vents face four directions (east, south, west, north), rotating the built-in filter changes the internal orientation so that each filter element corresponds to one of these four directions. For instance, if the built-in filter consists of four filter elements (A, B, C, D), before rotation, the correspondence between the filter elements and their directions is A-East, B-South, C-West, D-North. After rotation, the correspondence changes to B-East, C-South, D-West, A-North, and so on, until the correspondence matches the original state. The pollution level value is the pollution level of the air obtained after purification through the filter at the air vent.

[0116] Step S301: Under the built-in filter in the same internal position, determine the pollution ranking of each external position according to the pollution level value, and determine the purification ranking of the built-in filter according to the pollution level value obtained in the same external position.

[0117] External directional pollution ranking refers to the ranking of the pollution levels of all external sources. During the rotation and switching of the built-in filters, each filter element will correspond to different directions. At this time, the filtration capacity of the filter elements is the same. Therefore, the higher the corresponding pollution level value, the more severe the pollution in the corresponding external direction, and vice versa. Thus, this method can be used to determine the external directional pollution ranking. Internal filter purification ranking refers to the ranking of the filtration capacity of each filter element in the internal filter. During the rotation and switching of the built-in filters, each filter element will move to the same direction, and the pollution sources in that direction are the same. Therefore, the higher the pollution level value, the worse the filtration capacity of the corresponding filter element, and vice versa. Thus, this method can be used to determine the internal filter purification ranking.

[0118] Step S302: After the built-in filter rotates one revolution, a variable virtual position is established in the position where the internal orientation of the built-in filter is switched. The deviation parameters between each internal filter and the external orientation are determined in the virtual position according to the external orientation pollution sorting and the internal filter purification sorting.

[0119] The virtual position refers to the position when the correspondence between the internal filter and the external pollution source is different during the rotation of the internal filter. This position can change randomly. The correspondence between the internal filter and the external pollution source is different under different virtual positions. The deviation parameter is the absolute value of the difference between the order of the internal filter and the external orientation. For example, if the external pollution order is 3214, and the corresponding internal filter purification order is 1234, then the corresponding deviation parameters are 2, 0, 2, 0 respectively.

[0120] Step S303: Calculate and determine the error parameter based on all deviation parameters, determine the error parameter with the smallest value according to the sorting rules, define the virtual position corresponding to the error parameter as the appropriate working position, and control the built-in filter to rotate to the appropriate working position for operation.

[0121] Adding all the deviation parameters together yields the error parameter. A larger error parameter indicates a worse relationship between the built-in filter and the external pollution source. Theoretically, the filter with the strongest filtration capacity should be positioned to correspond to the area with the most severe external pollution to achieve the best air purification. Therefore, the error parameter with the smallest value is determined through a sorting rule to indicate that the current virtual position allows the air purifier to achieve a better air purification effect. This position is then defined as the appropriate operating position for the built-in filter to rotate and adjust, enabling the built-in filter to effectively filter air from all directions. Through the above technical solution, the filtration capacity of each filter can be made similar during the use of the built-in filter. That is, when one filter reaches the end of its service life, the remaining filters are also close to being scrapped, thereby reducing the waste of filter materials.

[0122] Reference Figure 4 After the error parameters are determined, the air purification method also includes:

[0123] Step S400: Determine whether there are at least two virtual positions with the same and smallest error parameters.

[0124] The purpose of the judgment is to determine whether there are multiple virtual locations that meet the requirements.

[0125] Step S4001: If there are no at least two virtual positions with the same and smallest error parameters, then determine the appropriate working position based on the unique virtual position.

[0126] When there are no at least two virtual positions with the same and smallest error parameters, it means that there is only one virtual position that meets the requirements. In this case, it is sufficient to determine the appropriate working position normally.

[0127] Step S4002: If there are at least two virtual positions with the same and smallest error parameters, the corresponding virtual position is defined as an optional position, and a fixed interval with a preset fixed duration is established on the preset time axis with the current time point as the end point.

[0128] When there are at least two virtual locations with the same and smallest error parameters, it indicates that there are multiple virtual locations that meet the requirements. At this time, it is necessary to filter the virtual locations. Define optional locations to distinguish different virtual locations and facilitate subsequent filtering. The time axis is a coordinate axis formed by the combination of various time points. The fixed duration is a fixed duration set by the staff to observe the user's historical data. Establish fixed intervals to facilitate the acquisition of historical data for each user.

[0129] Step S401: Within a fixed interval, define a similar time period based on the current time point, and determine the pollution source area corresponding one-to-one with the internal orientation of the internal filter based on the selectable location.

[0130] Similar time periods refer to time periods within a fixed interval that coincide with the current time. For example, if the current time is 7:00, the corresponding similar time period is 7:00-7:20 every day within the fixed interval. The size of the corresponding similar time period is set in advance by the staff. The pollution source area refers to the air area in the area where people can stand that can be filtered by a filter of an air purifier located in an optional position. In other words, the air in the pollution source area is filtered and purified by the internal filter in the corresponding internal position.

[0131] Step S402: Obtain the population change trend in the pollution source area within a similar time period.

[0132] The trend of population change in a region can be determined by the population changes at two endpoints of a similar time period. For example, if the population at the latter endpoint of a similar time period is 20 and the population at the former endpoint is 10, then the corresponding trend of population change in the region is an increasing trend.

[0133] Step S403: Determine the representative change trend in a single pollution source area based on the change in the number of people in the area, and correct the external pollution ranking based on the representative change trend.

[0134] The representative trend indicates the likely changes in the number of people in the pollution source area in the future. The specific method for determining this trend will be explained below. When the representative trend is an increasing trend, it means that the number of people in the area will increase, which will lead to an increase in pollution. Therefore, the corresponding position of the external location in the pollution ranking can be adjusted forward by one position to facilitate the subsequent screening of available locations.

[0135] Step S404: Recalculate and determine the error parameters based on the updated external orientation pollution sorting, determine the error parameter with the smallest value according to the sorting rules, and define the optional position corresponding to the error parameter as the appropriate working position.

[0136] The updated external pollution ranking allows for prediction of subsequent pollution changes in various areas. At this point, error parameters are redefined to select a unique and suitable operating location. This ensures that the currently determined suitable operating location is optimally suited to subsequent pollution changes in various external directions, resulting in the best overall performance of the air purifier without requiring adjustments to the internal filter position. (Reference) Figure 5 The steps for determining representative trends in a single pollution source area based on changes in the regional population include:

[0137] Step S500: Classify the regional population change trends into upward trends, stable trends, and downward trends.

[0138] An upward trend is a trend in which the number of people increases significantly; a stable trend is a trend in which the number of people does not change significantly; and a downward trend is a trend in which the number of people decreases significantly. The three different trends can be divided by setting corresponding points for changes in the number of people. For example, if the point for changes in the number of people is 5, when the number of people increases by more than 5, it is determined to be an upward trend; when the number of people decreases by more than 5, it is determined to be a downward trend; and the rest are stable trends.

[0139] Step S501: Count similar time periods corresponding to the population change trends in different regions to determine the trend time number, and calculate the trend representative percentage of the population change trends in each different region based on all the trend time numbers.

[0140] The trend time count is the number of times the population change trend in different areas occurs within a fixed approximation period. It can be obtained by counting similar time periods in which the corresponding trend occurs. The trend representative percentage is the proportion of the population change trend in each area. For example, if there are 10 population change trends in a single pollution source area, of which 7 are upward trends, 2 are stable trends, and 1 is downward trend, then the corresponding trend representative percentages are 70%, 20%, and 10%, respectively.

[0141] Step S502: Sort the pollution source areas from largest to smallest according to the trend representative proportion, and calculate the difference between the trend representative proportions of the top two in the sort to determine the difference trend proportion.

[0142] The difference trend percentage is the difference between the percentages of the two trends with larger values. In the example above, the corresponding difference trend percentage is 50%.

[0143] Step S503: Determine whether the percentage of the difference trend is greater than the preset demand percentage.

[0144] The demand ratio is the minimum difference trend ratio that staff must meet when the probability of subsequent population changes in the identified pollution source area is high. The purpose of this determination is to determine whether it is possible to predict subsequent population changes in the pollution source area. Step S5031: If the difference trend ratio is not greater than the demand ratio, then the stable trend is determined as the representative trend.

[0145] When the proportion of the difference trend is not greater than the proportion of demand, it means that it is impossible to predict the subsequent changes. In this case, the stable trend is determined as the representative trend to ensure the stability of the subsequent external pollution ranking.

[0146] Step S5032: If the proportion of the difference trend is greater than the proportion of demand, then the trend that appears first in the ranking is determined as the representative trend. When the proportion of the difference trend is greater than the proportion of demand, it means that the subsequent changes in the number of people can be predicted. At this time, the trend that appears first in the ranking is determined as the representative trend, so as to facilitate the subsequent correction of the ranking of external location pollution.

[0147] Reference Figure 6 The steps for revising the external orientation pollution ranking based on representative change trends include:

[0148] Step S600: Determine whether the trend of change is a stable trend.

[0149] The purpose of this judgment is to determine whether the external orientation pollution ranking needs to be corrected.

[0150] Step S6001: If the trend of change is stable, then maintain the original external orientation pollution sorting.

[0151] When the trend of change is stable, it means that it is impossible to predict the subsequent changes in the number of people or the changes in the number of people are not obvious. In other words, it can be determined that the changes in external pollution are not obvious, and the original external pollution ranking can be maintained.

[0152] Step S6002: If the representative trend is not a stable trend, then calculate the mean value based on the regional population change trend corresponding to the representative trend to determine the overall change mean.

[0153] When the representative trend is not a stable trend, it indicates that there is a change in the external pollution source, and further analysis is needed. The overall change mean is the average change in the number of people under the current representative trend. For example, if the representative trend is upward, the corresponding number of people with the upward trend in the fixed interval are 20, 10, 15, 14, 13, and 18 respectively, and the corresponding overall change mean is 15.

[0154] Step S601: Determine the correction parameters corresponding to the overall change mean based on the preset correction matching relationship.

[0155] Different overall change mean values ​​indicate different changes in the number of people, and at the same time, the corresponding degree of pollution change is also different. The corresponding correction parameter is the parameter that the pollution will affect the ranking. Different overall change mean values ​​correspond to different correction parameters, and the correction matching relationship between the two is determined by the staff in advance.

[0156] Step S602: Based on the representative trend of pollution change in the external orientation pollution ranking, calculate the difference between the corresponding pollution degree values ​​to determine the ranking interval.

[0157] For example, if the current external location is ranked third in the external location pollution sorting, and the corresponding trend is upward, then the corresponding sorting interval is the difference between the error value obtained by the third location in the external location pollution sorting and the error value obtained by the second location. If the corresponding trend is downward, then the corresponding sorting interval is the difference between the error value obtained by the third location in the external location pollution sorting and the error value obtained by the fourth location. This difference is the absolute value.

[0158] Step S603: Determine whether the correction parameter is greater than the sorting interval value.

[0159] The purpose of this judgment is to determine whether changes in the number of people will affect the sorting.

[0160] Step S6031: If the correction parameter is not greater than the sorting interval value, then maintain the original external orientation pollution sorting.

[0161] When the correction parameter is not greater than the sorting interval value, it means that the change in the number of people is not enough to compensate for the difference between the original sorting. In this case, it is sufficient to maintain the original external orientation pollution sorting.

[0162] Step S6032: If the correction parameter is greater than the sorting interval value, then the external orientation corresponding to the sorting interval value is sorted and swapped in the external orientation pollution sorting.

[0163] When the correction parameter is greater than the sorting interval value, it indicates that changes in the number of people will cause changes in the sorting of external pollution sources. In this case, the sorting positions of the two should be swapped for subsequent calculations.

[0164] Reference Figure 7 After the built-in filter is rotated to the appropriate working position for operation, the air purification method also includes:

[0165] Step S700: Determine whether the pollution level of the air purified by each air outlet is less than the preset permissible benchmark value.

[0166] The permissible baseline value is the minimum value set by the staff when the air is not effectively purified. The purpose of the judgment is to determine whether the air at each air outlet can be effectively filtered by the corresponding filter.

[0167] Step S7001: If the pollution level of the air purified by each air outlet is less than the permissible benchmark value, then control the built-in filter to maintain its original state.

[0168] When the pollution level of the air after purification at each vent is less than the permissible benchmark value, it means that the filters at each location can purify the air at each vent, and the original state can be maintained.

[0169] Step S7002: If the pollution level of the air purified by each air outlet is not less than the permissible benchmark value, then a suitable working position is re-determined from the remaining virtual positions according to the sorting rules, and the built-in filter is rotated to adjust to the updated suitable working position.

[0170] When the pollution level of the air purified by each vent is not lower than the permissible benchmark value, it indicates that some filters cannot meet the air purification requirements. At this time, a suitable working position is re-determined from the remaining virtual positions until all filters can meet the air purification requirements. When all positions cannot meet the requirements, it indicates that the filter has reached the end of its service life. At this time, an alarm signal is output so that the user can know the situation and clean or replace the filter.
