[0002] An air purifier is a device that can adsorb, decompose, or transform various air pollutants, effectively improving air cleanliness. Air pollutants generally include PM2.5, dust, pollen, odors, bacteria, formaldehyde, allergens, etc. As people's living standards improve, they are paying more and more attention to environmental health and have higher and higher requirements for air quality. Therefore, air purifiers are appearing more and more frequently in people's lives.

[0003] Currently, air purifiers generally have air quality detection and display modules, primarily using digital tube displays and color screens. For easier user viewing, some purifiers with color screen displays also include historical data query functions. However, due to the large amount of air quality data collected, the limited data displayed on the interface means that the displayed air quality data cannot accurately reflect changes in environmental quality. Summary of the Invention

[0004] This invention proposes a method, device, equipment, and storage medium for displaying and controlling air quality data, in order to solve the technical problem that the air quality data displayed by existing air purifiers cannot accurately reflect changes in environmental quality.

[0005] In one aspect, the present invention provides a method for displaying and controlling air quality data, the method comprising:

[0006] When the air purifier starts its purification function, it collects the first air quality data at the air inlet of the air purifier according to the preset data collection frequency.

[0007] When the running time of the air purifier exceeds the preset threshold for entering the data compression and display stage, the running time of the air purifier is divided into time periods for data collection. The mean, maximum and minimum values ​​of the first air quality data collected in each time period are extracted. Based on the maximum data display volume corresponding to the horizontal axis of the curve to be plotted, the mean values ​​of the multiple time periods closest to the current display time are updated and displayed in the form of a curve according to the order of collection time.

[0008] Furthermore, the method also includes:

[0009] When the running time of the air purification device is less than or equal to the time threshold for entering the data compression and display stage, multiple first air quality data within the time period closest to the current display time are updated and displayed sequentially in curve form according to the maximum data display volume corresponding to the horizontal axis of the curve to be plotted.

[0010] Furthermore, the method also includes:

[0011] When the running time of the air purification device is less than or equal to the preset time threshold for entering the data compression and display stage, the maximum and minimum values ​​of multiple first air quality data within the time period closest to the current display time are extracted, and the maximum and minimum values ​​are displayed.

[0012] When the running time of the air purifier exceeds the time threshold for entering the data compression and display stage, the maximum value and minimum value of the region are extracted from the multiple collection time periods closest to the current display time, and the maximum value and minimum value of the region are displayed.

[0013] Furthermore, the time period for collecting data on the operating time of the air purification equipment includes:

[0014] The number of data collection time periods to be divided is determined based on the running time of the air purification equipment and the maximum data display volume corresponding to the horizontal axis of the curve to be plotted.

[0015] The collection time periods are divided according to the number of collection time periods.

[0016] Furthermore, the method also includes:

[0017] During the first air quality data collection, the second air quality data at the air outlet of the air purification device at the corresponding collection time is also collected.

[0018] Based on the purification efficiency of the air purification equipment and the analysis of the second air quality data, the standard value range of the first air quality data at the corresponding collection time is determined.

[0019] Determine whether the first collected air quality data is within the standard value range;

[0020] If the first air quality data is not within the standard value range, the first air quality data is corrected, and the corrected data is displayed as the actual air quality data at the air inlet.

[0021] Furthermore, the correction of the first air quality data includes:

[0022] When the first air quality data is greater than the upper limit of the standard value range, the first air quality data is corrected to the upper limit value;

[0023] When the first air quality data is less than the lower limit of the standard value range, the first air quality data is corrected to the lower limit value.

[0024] Furthermore, the standard numerical range of the first air quality data at the corresponding collection time, analyzed based on the purification efficiency of the air purification device and the second air quality data, includes:

[0025] The purification efficiency of the air purification equipment is adjusted according to the preset tolerance value;

[0026] Calculate the standard value range of the first air quality data at the corresponding collection time based on the adjusted purification efficiency and the second air quality data:

[0027] The standard numerical range is The purification efficiency ranges from (a1, a2), D 出n is the second air quality data at the nth acquisition time, and b is the preset tolerance value.

[0028] Furthermore, when the running time of the air purification device is less than or equal to the preset time threshold for entering the data compression and display stage, the update frequency of the curve display is the same as the collection frequency of the first air quality data.

[0029] When the operating time of the air purifier exceeds the preset threshold for entering the data compression and display phase, the update frequency of the curve display will be reduced. Where f is the sampling frequency of the first air quality data. Where P represents the number of pixels on the horizontal axis of the air purification device's display.

[0030] Another aspect of the present invention also provides an air quality data display and control device, the device comprising:

[0031] The data acquisition module is used to collect the first air quality data at the air inlet of the air purifier according to the preset data acquisition frequency when the air purifier starts the purification function.

[0032] The display control module is used to divide the running time of the air purifier into time periods when the running time of the air purifier exceeds the preset time threshold for entering the data compression and display stage. It extracts the mean, maximum and minimum values ​​of the first air quality data collected in each time period. Based on the maximum data display volume corresponding to the horizontal axis of the curve to be plotted, it updates and displays the mean values ​​of multiple time periods closest to the current display time in the form of a curve according to the order of collection time.

[0033] The display control module is also used to update and display multiple first air quality data within the time period closest to the current display time in the form of a curve according to the maximum data display volume corresponding to the horizontal coordinate of the curve to be drawn, when the running time of the air purification device is less than or equal to the time threshold for entering the data compression and display stage.

[0034] In another aspect, the present invention provides an air quality data display and control device, comprising a device body and a controller. The controller includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the air quality data display and control method described above.

[0035] Furthermore, the device body includes a display device, at least one sensor disposed at the air inlet for collecting air quality data at the air inlet, and at least one sensor disposed at the air outlet for collecting air quality data at the air outlet.

[0036] Furthermore, the present invention also proposes a computer-readable storage medium storing a computer program thereon, which, when controlled by a processor, implements the steps of the air quality data display control method described above.

[0037] This invention proposes an air quality data display control method, device, equipment, and storage medium. When the air purification equipment operates for a long time, the operating time is divided into collection time periods. Key data of the first air quality data collected in each collection time period are extracted, including the mean, regional maximum value, and regional minimum value. This achieves data compression. Based on the maximum data display volume corresponding to the horizontal axis of the curve to be plotted, the mean values ​​of multiple collection time periods closest to the current display time are updated and displayed sequentially in curve form according to the collection time sequence.

[0048] Figure 1 The flowchart illustrating the air quality data display and control method proposed in an embodiment of the present invention is shown in the figure. Figure 1 As shown, the air quality data display and control method proposed in this embodiment of the invention includes the following steps:

[0049] S11. When the air purifier starts its purification function, it collects the first air quality data at the air inlet of the air purifier according to the preset data collection frequency.

[0050] In this embodiment of the invention, the air purification device has sensors installed at the air inlet and air outlet. Since inlet data better reflects ambient air quality, this invention primarily relies on the first air quality data (i.e., D) sent by the sensor at the air inlet when plotting historical air quality data curves. 进 ).

[0051] S12. When the running time of the air purifier exceeds the preset time threshold for entering the data compression and display stage, the running time of the air purifier is divided into time periods for data collection. The mean, maximum and minimum values ​​of the first air quality data collected in each time period are extracted. Based on the maximum data display volume corresponding to the horizontal axis of the curve to be plotted, the mean values ​​of the multiple time periods closest to the current display time are updated and displayed in the form of a curve according to the order of collection time.

[0052] In this embodiment of the invention, when the running time of the air purifier is less than or equal to a preset threshold for entering the data compression and display stage, the historical air quality data curve can be displayed using existing display methods. When the running time of the air purifier is relatively long, the running time of the air purifier is divided into collection time periods, and key data of the first air quality data collected in each collection time period, including the mean, regional maximum value, and regional minimum value, are extracted to achieve data compression. Based on the maximum data display volume corresponding to the horizontal axis of the curve to be plotted, the mean values ​​of multiple collection time periods closest to the current display time are updated and displayed sequentially in curve form according to the chronological order of collection time. This allows for a more accurate display of changes in ambient air quality without increasing costs, enabling users to better understand the changes in ambient air quality over historical time periods and providing a better user experience.

[0053] like Figure 2 As shown, the air quality data display control method proposed in this embodiment of the invention further includes the following steps: Step S13, when the running time of the air purification device is less than or equal to the time threshold for entering the data compression display stage, according to the maximum data display volume corresponding to the horizontal coordinate of the curve to be drawn, multiple first air quality data in the time period closest to the current display time are updated and displayed sequentially in the form of a curve according to the order of collection time.

[0054] Historical air quality data curves are as follows Figure 3 As shown, the horizontal axis represents time (t), and the vertical axis represents air quality data (d). Furthermore, the maximum and minimum values ​​can be displayed above the curve, representing the maximum and minimum air quality data for the first t period. Specifically, in this embodiment, when the running time of the air purification device is less than or equal to a preset threshold for entering the data compression and display stage, the maximum and minimum values ​​of multiple first air quality data within the time period closest to the current display time are extracted and displayed; when the running time of the air purification device exceeds the threshold for entering the data compression and display stage, the maximum regional maximum value and the minimum regional minimum value among the multiple collection time periods closest to the current display time are extracted and displayed.

[0055] When the purifier starts working, the sensor at the air inlet sends the collected air quality data to the display module of the air purifier at a preset data collection frequency f. Since the initial data collection is limited when plotting the historical air quality data curve, but the amount of data collected increases as the purifier runs, the curve display is divided into at least two stages to more accurately display historical changes in ambient air quality. Stage 1 is the normal data display stage, and Stage 2 is the data compression display stage. Let the purifier running time be T, and the time threshold for entering the data compression display stage be T2.

[0056] Phase 1 (0 <T<T2):

[0057] At this point, the historical air quality data curve update frequency is the same as the sensor's data acquisition frequency f; therefore, the horizontal axis of the curve in this stage is T1. Where P is the number of pixels on the horizontal axis, and the vertical axis of each point is the air quality data, i.e., Dn = D. 进 n refers to the nth air quality data point collected by the sensor. The maximum data display volume corresponding to the horizontal axis of the curve to be plotted is the maximum number of air quality data points that can be displayed within the time range corresponding to the horizontal axis T1.

[0058] Above the curve, the maximum and minimum air quality data (DMax and DMin) from the historical air quality data curve will be displayed. When the purifier's operating time T > T1, the curve displays the air quality data for the time period T1 most recent to the current display time.

[0059] When the operating time of the air purifier T > KT1, that is, T > T2, it enters stage 2.

[0060] In this embodiment, K is a constant, and the time threshold T2 for entering the data compression and display stage can be set to a multiple of T1, that is, T2 = KT1, where T2 is the time for dividing the two stages.

[0061] Phase 2 (T>T2):

[0062] At this point, the curve update frequency is: Its x-coordinate is The ordinate of each point is D′ m .

[0063] In this embodiment of the invention, when the running time of the air purifier is less than or equal to the preset time threshold for entering the data compression and display stage, the update frequency of the historical air quality data curve is the same as the collection frequency of the first air quality data; when the running time of the air purifier is greater than the preset time threshold for entering the data compression and display stage, the update frequency f′ of the historical air quality data curve is...

[0064] In stage 2, since sensor data will increase continuously as the air purification equipment runs longer, and storing a large amount of data will require a large amount of storage space, in order to better display the historical air quality data curve without increasing costs, this invention will determine the number m of the collection time periods to be divided based on the running time of the air purification equipment and the maximum data display volume corresponding to the horizontal axis of the curve to be plotted, and divide the collection time periods according to the number m of the collection time periods, where m refers to the number of time periods to be divided, m = 1, 2, ...

[0065] During working hours (Where m = 1, 2, ...) then each time period The sensor data in the data only retains its average value:

[0066]

[0067] Additionally, the m-th data collection time period is retained. The maximum value DMaxm and the minimum value DMinm within the region mean that the number of data points retained in each collection period has changed from the original K to the current 3 (D′). mClear all other data (DMaxm, DMinm) to better store subsequent data.

[0068] To address the issue of inaccurate air quality data due to occasional anomalies in sensor data collection, which affects display accuracy, the air quality data display control method disclosed in this invention further includes the following steps: When collecting first air quality data, collecting second air quality data from the air outlet of an air purifier at the corresponding collection time; analyzing the standard value range of the first air quality data at the corresponding collection time based on the purification efficiency of the air purifier and the second air quality data; determining whether the collected first air quality data falls within the standard value range; if the first air quality data does not fall within the standard value range, correcting the first air quality data and displaying the corrected data as the actual air quality data at the air inlet.

[0069] In this embodiment of the invention, air quality data is detected by matching multiple sensors. Specifically, the first air quality data collected by the air intake sensor is the main data, and the second air quality data collected by the air outlet sensor is the auxiliary data. Abnormal data in the first air quality data is corrected by using the second air quality data corresponding to the same collection time. In addition, the sensor data processing algorithm is used for adjustment, so that the air quality change curve can be displayed more accurately under the condition of limited storage space.

[0070] Furthermore, based on the purification efficiency of the air purification device and the analysis of the second air quality data, the standard numerical range of the first air quality data at the corresponding collection time includes: adjusting the purification efficiency of the air purification device according to a preset tolerance value; and calculating the standard numerical range of the first air quality data at the corresponding collection time based on the adjusted purification efficiency and the second air quality data.

[0071] The standard numerical range is The purification efficiency ranges from (a1, a2), D 出n is the second air quality data at the nth acquisition time, and b is the preset tolerance value.

[0072] Furthermore, the specific implementation method for correcting the first air quality data includes: when the first air quality data is greater than the upper limit of the standard value range, the first air quality data is corrected to the upper limit; when the first air quality data is less than the lower limit of the standard value range, the first air quality data is corrected to the lower limit.

[0073] Specifically, assuming the purifier's purification efficiency is a%, then D 出 =a%×D 进

[0074] The criteria for judging abnormal air quality data at the air inlet are as follows:

[0075] 1.

[0076] 2.

[0077] Where: a is an interval (a1, a2);

[0078] n refers to the data from the nth sensor;

[0079] b refers to the allowable error value, i.e., the tolerance value, and b < 1-a2.

[0080] When D 进n After identifying the anomaly, the historical curve will display the corrected data for that point:

[0081] like The curve then displays the corrected air intake data:

[0082]

[0083] Similarly, if Then display the data

[0084] It is understood that the display stages of the air quality curve can be increased or decreased according to the actual situation, and the time threshold for entering each stage can also be set according to the actual situation. This invention does not make specific limitations in this regard.

[0085] For the sake of simplicity, the method embodiments are described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously.
