Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The present embodiment provides a method of purifying air, as shown in fig. 1, the method of purifying air including:

and step 01, acquiring air index data of multiple directions, and judging the air pollution direction based on the air index data.

Optionally, the air specification data is air pollution concentration. The air pollution concentration includes harmful gas concentration, inhalable particle concentration, harmful microorganism concentration and the like.

The plurality of directions comprises a plurality of sub-direction groups; each of the sub-direction groups includes: a center point, a first direction, and a second direction, wherein the first direction and the second direction are opposite directions through the center point; by taking the example shown in fig. 2 as an example, the air pollution measuring instruments are arranged in 8 directions and at the central position, so that the air index data in the 8 directions can be monitored, and the first monitoring point, the second monitoring point and the central point are a first sub-direction group; the third monitoring point, the fourth monitoring point and the central point are a second sub-direction group. And reading air pollution data of each azimuth measuring instrument in real time, calculating air pollution direction vectors, and referring to air pollution concentration values of each monitoring point by N1-N9. In fig. 2, the first monitoring point represents the first direction monitoring to obtain N1, the center point monitoring to obtain N2, and the second monitoring point represents the second direction monitoring to obtain N3; the first monitoring point, the central monitoring point and the second monitoring point are on the same straight line, and the first direction and the second direction are opposite directions passing through the central point. The third monitoring point represents a third direction to obtain N4 through monitoring, and the fourth monitoring point represents a fourth direction to obtain N5 through monitoring; the third monitoring point, the central monitoring point and the fourth monitoring point are on the same straight line, and the third direction and the fourth direction are opposite directions passing through the central point.

And if the air index data in the multiple directions are equal or the difference value of the air index data in any two directions in the multiple directions is within a preset range, judging that the current position is the air pollution direction. For example, when N1 ═ N2 ≈ N3 is equal or N1 ≈ N2 ≈ N3 (the difference between N1, N2, and N3 is within a preset accuracy error range), and the 8 directions simultaneously satisfy the above conditions, it is determined that the current indoor air pollution is relatively uniform, and it is not necessary to move the air cleaning device, and it is determined whether the air needs to be cleaned according to the measurement instrument data.

And comparing the air index data in the first direction, the air index data in the central point and the air index data in the second direction to obtain the direction with the maximum air index data, and judging the direction with the maximum air index data as the air pollution direction. For example, when the conditions of N3> N2> N1 are satisfied, it is determined that air pollution is more serious in the right direction than in the left direction and the pollution source is in the right direction, and similarly, when the conditions of N3< N2< N1 are satisfied, it is determined that air pollution is more serious in the left direction than in the right direction and the pollution source is in the left direction.

And each of the at least two sub-direction groups comprises a direction in which the air index data is maximum, and the air pollution direction is obtained based on the direction in which the at least two air index data is maximum. For example, N3> N2> N1 and N5> N2> N4, vector directions are finally calculated in a comprehensive manner based on the vector magnitude in each direction, and the directions of 30 ° and 165 ° are obtained, for example. For example, the angle is calculated according to the sensor orientation, such as N3-N2 being 1, N5-N2 being 1, (N3-N2)/(N3+ N5-2N2) being 0.5, and if the line connecting the second monitoring point and the center monitoring point and the line connecting the fourth monitoring point and the center monitoring point are perpendicular to each other, the moving direction of the air cleaning device is deviated from 0.5 by 90 ° to 45 °. Alternatively, if a plurality of direction conditions are satisfied, one direction may be randomly selected to move, and the real-time dynamic adjustment may be performed according to steps 01 to 03.

Step 02: moving along the air pollution direction. After the direction of the air pollution direction is calculated, the air purification device is moved along the direction.

When the condition N3 is satisfied, N2< N1, N3 is approximately equal to N2< N1, or N3 is approximately equal to N2 and the difference value with N1 is within a certain error range, the current position is a pollution source, the air purification device does not move, and the purification function is directly started.

Step 03, judging whether the current position is a pollution source in real time in the moving process, if so, stopping moving and starting a purification function; if not, repeating the step 01 to the step 03. And when the air purification device is moved, the direction vector of the air pollution is continuously calculated, and the moving direction is adjusted in real time according to the directions of the vectors at different positions. After the pollution source is positioned, cleaning of polluted air is started, in order to accelerate the air pollution cleaning efficiency, after a period of time, the direction vector of air pollution is determined again according to the data of the measuring instrument, and the position with the most serious air pollution is positioned for cleaning.

After step 03, the method further comprises: and judging whether the air index data in the multiple directions are all lower than a preset threshold value, if so, closing the purification function. Finally, indoor harmful gas and inhalable particles can be generated, and harmful microorganisms are reduced to below a certain concentration, and then cleaning is finished.

The determining unit 20 is further configured to compare the air index data of the first direction, the air index data of the central point, and the air index data of the second direction to obtain a direction in which the air index data is the largest, and determine the direction in which the air index data is the largest as the air pollution direction.
