Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to fig. 1-7 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The embodiments of the present invention will be described in further detail with reference to the drawings.

Referring to fig. 1, an embodiment of the present invention provides an air purification method, and a main flow of the air purification method is described as follows:

step 100: dividing the whole environment according to the preset area, numbering, and acquiring the current area number information corresponding to each area.

The current region number information is information of a number corresponding to each region after the whole detection region is divided according to the region. The manner of acquisition is input in advance by a person skilled in the art. The dividing method is to divide according to different types of each working area, for example, two areas are respectively welding and cutting areas, in the embodiment of the application, the divided areas are separated by a fence, that is, air does not intercommunicate between the two areas. For example: there are four total regions within the detection area, numbered 1, 2, 3 and 4.

Step 101: and acquiring current air quality information corresponding to the current region number information.

The current air quality information is information of a numerical value corresponding to the detected air quality. The acquisition method is any device or equipment capable of detecting air quality. For example, an air quality sensor, which is placed in each zone and is associated with the current zone number information of each zone, i.e., an air quality value sensed by an air quality sensor in a zone. In the embodiment of the present application, the value representing the air quality in the current air quality information may be a value with the worst or the best air quality, or may be an average value of values of the air quality at a plurality of positions.

Step 102: and comparing the purification wind speed stored in the preset air purification processing database with the current air quality information to determine the purification wind speed corresponding to the current air quality information, and defining the purification wind speed as required purification wind speed information.

The required purification wind speed information is gear information of the purification wind speed corresponding to the current air quality information. The air purification process database is determined and input by the worker in the art based on the past experiments, and is a mapping relationship between the shift of the purification wind speed and the range of the air quality value. The matching method comprises the steps of inputting the current air quality information into the database, matching the current air quality information with the range of the air quality value in the database, determining the range of the current air quality information, and inputting the required purification wind speed information in the corresponding range.

Step 103: matching the wind speed corresponding to the required purification wind speed information with the preset wind speed corresponding to the current wind speed information.

The preset current wind speed information is information of a current wind speed gear, and is a wind speed gear manually dialed by a worker according to own experience and the feeling of standing in a corresponding area. The matching of the wind speed is the matching of two gears, and is numerical comparison.

Step 1031: and if the wind speed corresponding to the required purification wind speed information is the same as the wind speed corresponding to the current wind speed information, not changing the wind speed of the purification device in the area corresponding to the current area number information.

If the wind speed corresponding to the required purification wind speed information is the same as the wind speed corresponding to the current wind speed information, it is indicated that the wind speed corresponding to the current wind speed information can meet the purification efficiency of the area corresponding to the current air quality information and is adaptive to each other, and the wind speed of the purification device does not need to be adjusted.

Step 1032: and if the wind speed corresponding to the required purification wind speed information is different from the wind speed corresponding to the current wind speed information, updating the wind speed of the purification device in the area corresponding to the current area number information to the wind speed corresponding to the required purification wind speed information.

If the wind speed corresponding to the required purification wind speed information is different from the wind speed corresponding to the current wind speed information, the current wind speed and the required purification wind speed information are not adaptive, the purification requirement cannot be met, and the system automatically adjusts the wind speed gear corresponding to the required purification wind speed information.

Referring to fig. 2, a wind speed adjusting method between adjacent zones includes:

step 200: and acquiring the number information of the left adjacent area and the number information of the right adjacent area corresponding to the number information of the current area.

The number information of the left adjacent region and the number information of the right adjacent region are only represented as the number information of two regions adjacent to the current region, and do not represent the left side and the right side in the actual sense, that is, the number information of the left adjacent region and the number information of the right adjacent region respectively correspond to the information of the region with one lower number and the region with one higher number, and when the number of the current region is the minimum, the number of the left adjacent region is the region corresponding to the maximum number. The obtaining method can be obtained by calculation through a calculation formula, or can be directly searched in a database, namely the database stores the mapping relation between the number of the current area and the number information of the left adjacent area and the number information of the right adjacent area.

Step 201: and comparing the current air quality information corresponding to the number information of the left adjacent area with the current air quality information corresponding to the number information of the right adjacent area to obtain an area with a smaller numerical value corresponding to the current air quality information, and defining the number corresponding to the area as the number information of the high-quality area.

The high-quality area number information indicates the number of the area having the high air quality. The current air quality information corresponding to the number information of the left adjacent area and the number information of the right adjacent area is obtained by sensing through an air quality sensor arranged in the corresponding area, the comparison method is the comparison of the air quality value, and the larger the air quality value is, the worse the air is. And then screening out the number information of a region with a smaller air quality value, namely a region with better air quality, namely a high-quality region.

Step 202: and calculating the current air quality information of the current region number information and the current air quality information of the high-quality region number information to determine the poor quality degree information.

The quality difference degree information is information of the degree of difference between a current air quality value of the current area and a better air quality value of the neighboring area, and the quality difference degree information Δ H = (AQIh-AQIx)/AQIx, wherein AQIh represents current air quality information of the high-quality area number information, AQIx represents current air quality information of the current area number information, and the quality difference degree information is represented by percentage.

Step 203: and judging whether the quality difference degree information is larger than the preset standard degree information.

The standard degree information is information of a standard value of the degree of difference in the numerical value of the air quality between the two areas, the specific numerical value being determined by a person skilled in the art through long-term experience, and being 10% in the embodiment of the present application. The purpose of the judgment is to determine whether the degree corresponding to the quality difference degree information exceeds a certain value, so as to determine whether the wind speed needs to be changed.

Step 2031: and if the quality difference degree information is larger than the preset standard degree information, performing matching analysis according to the gear stored in the preset wind speed corresponding database and the current purification wind speed information to determine a higher gear wind speed corresponding to the current purification wind speed information, and defining the gear wind speed as strong purification wind speed information.

The strong purification wind speed information is the purification wind speed information of a gear wind speed higher than the current purification wind speed information, the wind speed corresponding database is the mapping relation of the current purification wind speed information and the strong purification wind speed information which are set in advance, namely when the gear corresponding to the current purification wind speed information is input, the wind speed information higher than the gear corresponding to the current purification wind speed information by one gear can be searched from the database, and the information is the strong purification wind speed information. And if the information of the quality difference degree is larger than the preset standard degree information, the quality difference degree is shown to reach the degree that the wind speed needs to be changed to achieve the effect of accelerating the purification.

Step 2032: and if the quality difference degree information is smaller than the preset standard degree information, ventilating the purification devices in the area corresponding to the current area number information according to the wind speed corresponding to the current purification wind speed information.

If the information of the quality difference degree is smaller than the preset standard degree information, the quality difference degree does not reach the degree that the wind speed needs to be changed to achieve the effect of accelerating the purification, and the change is not needed.

Step 204: and judging whether strong purification wind speed information exists or not.

The purpose of the judgment is to determine whether the current purification wind speed information reaches the maximum gear, and if the previous purification wind speed information reaches the maximum gear, the strong purification wind speed information searched from the database is absent.

Step 2041: and if the strong purification wind speed information exists, calculating the quality difference degree information, the current purification wind speed information and the strong purification wind speed information corresponding to the current purification wind speed information according to a preset wind speed acceleration calculation formula to determine the wind speed increase amount, and defining the wind speed increase amount as wind speed increase information.

The wind speed acceleration calculation formula is a calculation formula of the calculated wind speed increase amount when the current purification wind speed information does not reach the maximum gear wind speed. The wind speed increase amount Δ S =Δh (S1-S2), where S1 is the gear wind speed corresponding to the strong purification wind speed information, and S2 is the gear wind speed corresponding to the current purification wind speed information. If the strong purification wind speed information exists, which indicates that the current purification wind speed information does not reach the maximum gear wind speed, the wind speed increasing amount can be calculated according to a wind speed acceleration calculation formula, and the wind speed is increased.

Step 2042: and if the strong purification wind speed information does not exist, calculating the quality difference degree information and the current purification wind speed information according to a preset maximum gear wind speed acceleration calculation formula to determine the maximum gear wind speed increase amount, and defining the maximum gear wind speed increase amount as maximum gear wind speed increase information.

The maximum gear wind speed acceleration calculation formula is a calculation formula of the calculated wind speed increase amount when the current purified wind speed information reaches the maximum gear wind speed. And increasing the maximum gear wind speed by the amount delta Smax =deltaH 0.15 Smax, wherein the Smax is the wind speed when the current purified wind speed information reaches the maximum gear wind speed. If the strong purification wind speed information does not exist, the current purification wind speed information is shown to reach the maximum gear wind speed, and the wind speed increasing amount can be calculated according to the maximum gear wind speed acceleration calculation formula and the wind speed is increased.

Step 205: and calculating the wind speed increasing information and the current purification wind speed information to obtain the current wind speed information.

The current wind speed information is wind speed information obtained by adding wind speed values corresponding to the wind speed increasing information and the current purification wind speed information, and represents a wind speed value which can be achieved theoretically.

Step 206: and calculating the maximum gear wind speed increasing information and the current purification wind speed information to obtain the maximum gear wind speed information.

The maximum gear wind speed information is wind speed information obtained by adding the maximum gear wind speed increasing information and the wind speed value corresponding to the current purification wind speed information, and represents a theoretically achievable wind speed value.

Step 207: and performing matching analysis according to the limit value of the wind speed increment stored in the preset wind speed increment database and the strong purification wind speed information to determine the limit value of the wind speed increment corresponding to the strong purification wind speed information, and defining the limit value as the current limit wind speed information.

The current limit wind speed information is information of a limit value of the wind speed increasing amount, which is expressed as a limit wind speed that cannot be exceeded according to the wind speed increasing amount, and the limit wind speed is related to the wind speed of the next gear. The mapping relation between the strong purification wind speed information and the current limit wind speed information is stored in the wind speed increasing database. And when strong purification wind speed information is input, searching the current limit wind speed information from the database. After many experiments, the current limit wind speed information Sx =0.9 × S1 is obtained by those skilled in the art.

Step 208: and performing matching analysis according to the limit value of the wind speed increment stored in the wind speed increment database and the maximum gear wind speed information to determine the limit value of the maximum gear wind speed increment corresponding to the maximum gear purification wind speed information, and defining the limit value as the maximum gear limit wind speed information.

The maximum gear wind speed limit information is information of a limit value of wind speed increase amount, and is represented as a limit wind speed which cannot be exceeded according to the wind speed increase amount of the maximum gear, and the limit wind speed is related to the wind speed of the maximum gear. The mapping relation between the strong purification wind speed information and the current limit wind speed information is stored in the wind speed increasing database. And when the maximum gear purification wind speed information is input, searching the maximum gear limit wind speed information from the database. After many experiments, the maximum gear limit wind speed information Sy =1.15 Smax is obtained by those skilled in the art.

Step 209: and comparing the wind speed corresponding to the current wind speed information with the wind speed corresponding to the current limit wind speed information.

The way of comparison is that the two wind speeds are numerically subtracted.

Step 2091: and if the wind speed corresponding to the current wind speed information is larger than the wind speed corresponding to the current limit wind speed information, updating the wind speed increasing information according to the current limit wind speed information.

If the wind speed corresponding to the current wind speed information is larger than the wind speed corresponding to the current limit wind speed information, it indicates that after the wind speed is increased according to the calculated wind speed increase information, the wind speed corresponding to the current wind speed information exceeds the wind speed corresponding to the current limit wind speed information, and the purification device is easily burnt out when working because the working power of the motor exceeding the gear is large, so the wind speed increase information needs to be updated according to the current limit wind speed information, and the motor is prevented from being damaged.

Step 2092: and if the wind speed corresponding to the current wind speed information is less than the wind speed corresponding to the current limit wind speed information, the wind speed increasing information is not adjusted.

If the wind speed corresponding to the current wind speed information is less than the wind speed corresponding to the current limit wind speed information, the wind speed corresponding to the current wind speed information does not exceed the wind speed corresponding to the current limit wind speed information and is at a safe value, and the wind speed can be increased according to the wind speed increasing information.

Step 210: and comparing the wind speed corresponding to the maximum gear wind speed information with the wind speed corresponding to the maximum gear limit wind speed information.

The way of comparison is that the two wind speeds are numerically subtracted.

Step 2101: and if the wind speed corresponding to the maximum gear wind speed information is larger than the wind speed corresponding to the maximum gear limit wind speed information, updating the maximum gear wind speed increasing information into the maximum gear limit wind speed information.

If the wind speed corresponding to the maximum gear wind speed information is larger than the wind speed corresponding to the maximum gear limit wind speed information, it indicates that after the wind speed is increased according to the calculated maximum gear wind speed increase information, the wind speed corresponding to the maximum gear wind speed information exceeds the wind speed corresponding to the maximum gear limit wind speed information, and the purification device is easily burnt out when working because the working power of the motor exceeding the gear is large, so the maximum gear wind speed increase information needs to be updated according to the maximum gear limit wind speed information, and the motor is prevented from being damaged.

In step 2102, if the wind speed corresponding to the maximum gear wind speed information is smaller than the wind speed corresponding to the maximum gear limit wind speed information, the maximum gear wind speed increasing information is not adjusted.

If the wind speed corresponding to the maximum gear wind speed information is smaller than the wind speed corresponding to the maximum gear limit wind speed information, it is indicated that the wind speed corresponding to the maximum gear wind speed information does not exceed the wind speed corresponding to the maximum gear limit wind speed information, and is at a safe value, and the wind speed can be increased according to the maximum gear wind speed increasing information.

Step 211: and adjusting the wind speed of the purification device in the area corresponding to the current area number information according to the wind speed increasing information.

Step 212: and adjusting the wind speed of the purification device in the area corresponding to the current area number information according to the maximum gear wind speed increasing information.

Referring to fig. 3, the method for selecting the location of the air purification apparatus in the same area includes:

step 300: and acquiring the optimal air quality information and the worst air quality information.

The optimal air quality information and the worst air quality information are information of air quality values and coordinates corresponding to the minimum and maximum values among detected corresponding air quality values in the same region. The acquisition method can be used for acquiring a plurality of air quality sensors at different positions, and can also be used for acquiring one air quality sensor through movement.

Step 301: and drawing a blowing track on the electronic map according to the coordinate points corresponding to the optimal air quality information and the worst air quality information, and defining the blowing track as blowing track information.

The blowing track information is information of a connecting line of coordinate points corresponding to the optimal air quality information and the worst air quality information on the electronic map, and also comprises the coordinate points and direction angles corresponding to the optimal air quality information and the worst air quality information. Namely, when the optimal air quality information and the worst air quality information are determined, coordinate points corresponding to the two information are marked on the electronic map, then the two points are connected, and the blowing track information has a direction, namely, the blowing track information faces to the coordinate point corresponding to the worst air quality information from the coordinate point corresponding to the optimal air quality information.

Step 302: and moving the purification device to a coordinate point corresponding to the optimal air quality information and blowing air according to the blowing track information.

And the purification device moves to the starting point of the blowing track information, namely the coordinate point corresponding to the optimal air quality information, and then blows air according to the angle of the blowing track information. The aim of blowing in this way is to simultaneously blast the poor air by means of the air in the region of good air quality, reducing the power of the purification device.

Referring to fig. 4, the method for acquiring the optimal air quality information and the worst air quality information includes:

step 400: and the air quality sensor moves according to the preset circulating track and acquires the current coordinate information in real time.

The circular orbit is the position and travel of the air quality sensor moving in the detection area, for example, fig. 6, and the distance from the starting point to the ending point is a patrol distance covering all positions in the area. The end point return starting point is a return route, and can be any route. One patrol route and one return route are a loop. The current coordinate information is information of a coordinate point of a position to which the air quality sensor moves.

Step 401: and judging whether the coordinate point corresponding to the current coordinate information is coincident with the coordinate point corresponding to the preset starting point information or end point information.

The start point information and the end point information are points at which detection is started and points at which detection is finished, which are preset in the area in advance. The purpose of judgment is to control the on-off of the air quality sensor.

Step 4011: and if the coordinate point corresponding to the current coordinate information is coincident with the coordinate point corresponding to the preset starting point information, the air quality sensor starts to measure the air quality, the air quality value acquired at the starting point information is defined as initial air quality information, and the updated optimal air quality information and the worst air quality information are the air quality value corresponding to the initial air quality information and the coordinate point corresponding to the initial air quality information.

The initial air quality information is information of the air quality value and the coordinate point acquired at the start point information. If the coordinate point corresponding to the current coordinate information is overlapped with the coordinate point corresponding to the preset starting point information, the fact that the air quality sensor reaches the starting point is indicated, and detection needs to be started. The purpose of updating is to initialize the optimal air quality information and the worst air quality information and restart the calculation, and the optimal air quality information and the worst air quality information of the last cycle are not easily influenced.

Step 4012: if the coordinate point corresponding to the current coordinate information is coincident with the coordinate point corresponding to the preset end point information, the air quality sensor does not measure the air quality and continues to run, and the purification device moves to the coordinate point corresponding to the optimal air quality information and blows air according to the air blowing track information.

If the coordinate point corresponding to the current coordinate information coincides with the coordinate point corresponding to the preset end point information, which indicates that the air quality sensor has moved to the end point and completed the detection of one circle, the air quality sensor needs to be closed, and the situation that the detection is still performed in the process of returning to the starting point position, which affects the determination of the optimal air quality information and the worst air quality information, is prevented. And when the terminal point is reached, the purification device moves to the coordinate point corresponding to the optimal air quality information to start working.

Step 4013: if the coordinate point corresponding to the current coordinate information is not coincident with the preset coordinate point corresponding to the starting point information and the end point information, the air quality sensor keeps the existing state to move continuously, and the purifying device keeps the existing state.

If the coordinate point corresponding to the current coordinate information does not coincide with the coordinate point corresponding to the preset starting point information and the preset end point information, the coordinate point is neither at the starting point nor at the end point, if the coordinate point is from the starting point to the end point, the air quality sensor is kept in an open state, and the purification device works at the position with the optimal air quality information of the last cycle; if the air quality sensor is in the end point to the starting point, the air quality sensor is kept in a closed state, and the purification device works at the position of the optimal air quality information of the current cycle. Therefore, the purification device moves after only one cycle is maintained, so that the position and the angle can be updated in real time according to the updated conditions of the optimal air quality information and the worst air quality information, and the purification device is flexible and efficient.

Step 402: and the air quality sensor continues to run, acquires corresponding air quality values and coordinate points according to a certain time interval, and defines the air quality corresponding to different coordinate points as instant air quality information.

The instant air quality information is information of the corresponding air quality value and the coordinate point which are obtained by the air quality sensor according to a certain time interval in the driving process. For example, in fig. 6, the instantaneous air quality information is information within any one of the circles.

Step 403: and comparing the air quality value corresponding to the instant air quality information with the air quality value corresponding to the optimal air quality information.

The comparison of the two is a numerical comparison, and the purpose of the comparison is to determine a coordinate point of the optimal air quality information.

Step 4031: and if the air quality value corresponding to the instant air quality information is larger than the air quality value corresponding to the optimal air quality information, comparing the air quality value corresponding to the instant air quality information with the air quality value corresponding to the worst air quality information.

If the air quality value corresponding to the instant air quality information is larger than the air quality value corresponding to the optimal air quality information, the fact that the air quality at the coordinate point corresponding to the instant air quality information is worse than the air quality corresponding to the optimal air quality information is shown, and whether the air quality is worse than the air quality corresponding to the worst air quality information is judged.

Step 4032: and if the air quality value corresponding to the instant air quality information is smaller than the air quality value corresponding to the optimal air quality information, updating the optimal air quality information and deleting the instant air quality information.

And if the air quality value corresponding to the instant air quality information is smaller than the air quality value corresponding to the optimal air quality information, the fact that the air quality corresponding to the instant air quality information is superior to the air quality corresponding to the optimal air quality information is shown, and the optimal air quality information is not the optimal point, the optimal air quality information is updated to be the air quality value corresponding to the instant air quality information and the coordinate point.

Step 4041: and if the air quality value corresponding to the instant air quality information is larger than the air quality value corresponding to the worst air quality information, updating the worst air quality information and deleting the instant air quality information.

And if the air quality value corresponding to the instant air quality information is larger than the air quality value corresponding to the worst air quality information, and the point where the worst air quality information is not the worst indicates that the air quality corresponding to the instant air quality information is worse than the air quality corresponding to the worst air quality information, updating the worst air quality information into the air quality value corresponding to the instant air quality information and the coordinate point.

Step 4042: and if the air quality value corresponding to the instant air quality information is smaller than the air quality value corresponding to the worst air quality information, neither the optimal air quality information nor the worst air quality information is updated.

And if the air quality value corresponding to the instant air quality information is smaller than the air quality value corresponding to the worst air quality information, indicating that the instant air quality information is in the air quality between the optimal air quality information and the worst air quality information, and if the instant air quality information does not affect the optimal air quality information and the worst air quality information, not updating.

Referring to fig. 5, the method of placing the purification apparatus includes:

step 500: and if the air quality value corresponding to the instant air quality information is consistent with the air quality value corresponding to the optimal air quality information, marking the coordinate corresponding to the instant air quality information, obtaining a marking map corresponding to all coordinates, and defining the marking map as the extreme value marking map information.

The extreme-optimal value label graph information is a label graph corresponding to all coordinates, wherein the air quality value corresponding to the instant air quality information on the electronic map is consistent with the optimal air quality information. When one or even a few instant air quality information detected after having been provided with the signature is found to be better than the optimal air quality information, the signature is restarted and the existing signature is deleted.

Step 501: and performing matching analysis according to the central point coordinate stored in the preset coordinate center database and the extreme value label graph information to determine the central point coordinate corresponding to the extreme value label graph information, and defining the central point coordinate as the extreme value central point information.

The coordinate center database is a mapping relation between any marking map information and the center point coordinates thereof. The coordinate center database is obtained by calculating and storing the center point data of any one of the marker maps for a limited number of times by those skilled in the art. When the corresponding extreme merit figure information is input, namely after all coordinate points of the optimal air quality information are input, the corresponding center point coordinate can be automatically searched in the database and output to the purification device.

Step 502: and updating the coordinate point of the optimal air quality information into the central point coordinate corresponding to the central point information of the maximum value.

The updating mode is numerical value replacement, and the purpose of updating is to give a moving coordinate point to the purification device.

Step 503: and if the air quality value corresponding to the instant air quality information is consistent with the air quality value corresponding to the worst air quality information, marking the coordinates corresponding to the instant air quality information to obtain a marking map corresponding to all the coordinates, and defining the marking map as extreme difference value marking map information.

And the range marking map information is a marking map corresponding to all coordinates with consistent air quality values corresponding to the instant air quality information and the worst air quality information on the electronic map. When one or even a few instant air quality information detected after having been provided with the signature is found to be worse than the worst air quality information, the signature is restarted and the existing signature is deleted.

Step 504: and performing matching analysis according to the central point coordinate stored in the preset coordinate center database and the range value mark map information to determine the central point coordinate corresponding to the range value mark map information, and defining the central point coordinate as the range value central point information.

The coordinate center database contains the mapping relation between any marking map information and the coordinates of the center point thereof. The coordinate center database is obtained by calculating and storing the center point data of any one of the marker maps for a limited number of times by those skilled in the art. When the polar difference value marking map information is input, namely after all coordinate points of the worst air quality information are input, the corresponding center point coordinate can be automatically searched in the database and output to the purification device.

Step 505: and updating the coordinate point of the worst air quality information into the central point coordinate corresponding to the extreme value central point information.
