According to an embodiment of the present invention, in step S101, dust sensors are disposed at a plurality of preset positions around a building to be tested, where the dust sensors include a laser array and a receiver array, the laser array includes a plurality of lasers, the lasers are used to emit laser beams with preset frequencies and preset light intensities, the receiver array includes a plurality of receivers, each receiver is respectively used to receive the laser beams with preset frequencies emitted by one laser, and determine the light intensities of the received laser beams, a first preset distance is provided between the laser array and the receiver array, for example, dust sensors are disposed at a plurality of preset positions around the building to be tested, the sensors include receivers and lasers corresponding to each other one, the lasers can emit laser beams with specific light intensities, the laser beams are distinguished from natural light, the receivers are set to receive the light intensities of the preset frequencies, interference caused by the natural light to the light intensities of the laser beams can be avoided, the greater the light intensities received by the receivers are compared with the light intensities emitted by the lasers, the light intensities of the receivers, the space between the receivers and the laser beams is more severely polluted by dust in the air, and the dust in the space between the receivers is more seriously polluted, and the dust sensor data is recorded by the dust sensors corresponding to the plurality of positions around the building to be tested, and the dust sensors are disposed one by one more accurately. The three-dimensional position of each dust sensor can be manually measured when each dust sensor is installed, and the three-dimensional position is stored in a processor for executing the construction dust fall control method for the processor to call.
According to one embodiment of the present invention, in step S102, dust sensors at a plurality of preset positions are turned on, so that each laser in the laser array emits laser light, and light intensity information received by each receiver in the receiver array is obtained, for example, light intensity emitted by the laser is preset light intensity, light intensity received by the receiver is light intensity information, in general, the closer the light intensity information is to the preset light intensity, the less the laser is blocked, the less dust in the air is, and the greater the difference between the light intensity information and the preset light intensity is, the more the laser is blocked, and the more dust in the air is.
According to one embodiment of the present invention, in step S103, the dust pollution evaluation score of the position where each dust sensor is located is determined according to the light intensity information received by the plurality of receivers of each receiver array, for example, each receiver array has a plurality of receivers, the light intensity information of the three-dimensional position where the sensor is located is obtained by using the information of the plurality of receivers, and the pollution evaluation score of the position where the sensor is located is calculated by using the light intensity information of the sensor, so that the dust pollution condition of the position is evaluated.
According to one embodiment of the present invention, determining dust pollution evaluation scores at positions of each dust sensor based on light intensity information received by a plurality of receivers of each receiver array includes: determining a target receiver of the plurality of receivers of the receiver array, wherein the received light intensity information is greater than or equal to a first light intensity threshold; determining a number duty cycle of the target receiver among the plurality of receivers; and determining the dust pollution evaluation score according to the preset light intensity, the light intensity information received by the target receiver and the quantity ratio. The receiver for which a part of the data is available is determined as the target receiver, i.e. the target receiver for which the light intensity information is greater than or equal to the first light intensity threshold value, and a part of the receiver may be almost completely blocked, and the collected data is useless data, so that the data can be directly considered as 0 without using the data. The quantitative ratio may be calculated, and the dust pollution evaluation score may be calculated based on the quantitative ratio.

The preset light intensity is the original light intensity emitted by the emitter, and the closer the light intensity information is to the original light intensity, the less dust is, < ->The smaller the value of (c) the closer the actually detected light intensity is to the original light intensity, the less pollution in the air, the lower the pollution evaluation score, +.>The greater the value of (2), the greater the difference between the actual detected light intensity and the original light intensity, the more pollution in the air, the greater the pollution evaluation score, +.>As the first light intensity threshold value, the light intensity received by the receiver is influenced by refraction or reflection of light, the data of the light intensity below the threshold value is distorted, and the shielding relation with the evaluating dust is not large, so that +.>The value of (2) is denominator, < >>For the average condition of dust pollution calculated from the effective light intensity information at the jth dust sensor position, the term is multiplied by the number-to-number ratio K to obtain the average condition of dust pollution, i.e., the dust pollution evaluation score, determined by all the receivers at this position.
In this way, the light intensity information of data distortion can be eliminated, the average state of dust pollution is determined by utilizing the light intensity information with effective data, and then the average state of dust pollution of the whole position determined by all the receivers, namely, the dust pollution evaluation score, is calculated by utilizing the quantity ratio, so that the accuracy of the dust pollution evaluation score is improved.
According to an embodiment of the present invention, in step S104, a relation function between the dust pollution evaluation score and the position coordinates is determined according to the dust pollution evaluation score of the position where each dust sensor is located and the position coordinates of the preset position where each dust sensor is located, for example, the dust pollution evaluation score of the limited position coordinates is used to calculate the dust pollution degree of an infinite number of positions, and the method may be further used to classify dust types, where different types of dust have different influences on the surrounding environment.
According to one embodiment of the invention, in step S105, the coefficient of influence of dust on the surrounding environment is determined from the relation function. For example, the greater the extremum of the relationship function, the greater the amount of dust pollution in the air, by means of which the influence on the surrounding environment can be inferred.
According to one embodiment of the invention, determining the influence coefficient of dust on the surrounding environment according to the relation function comprises: establishing a coordinate system by taking the centroid of the ground where the building to be tested is located as a coordinate origin;

The conditional function in the molecule means that when the relation function value at a certain point on the cylindrical surface is equal to or more than +.>The value of the conditional function is the relation function +.>The function value of the point is 0 otherwise, the curved surface integral of the condition function can represent the integral of the relation function value of the point with stronger pollution (the point which can effectively represent dust pollution), the effective flux of the pollution on the cylindrical surface can be obtained, the diffusion quantity of the dust pollution on the cylindrical surface to the external environment can be represented, and the point is the effective flux of the pollution on the cylindrical surface>The average concentration of the contaminants on the active area, which is equal to the effective flux divided by the active area, can be used as the contamination score.
By the method, the effective area formed by the collection of the points with strong pollution on the cylindrical surface can be obtained through the condition function, the effective flux of the pollution of the points with strong pollution on the cylindrical surface can be solved through the condition function, the pollution grade on the cylindrical surface can be obtained, the average pollution concentration of the effective area on the cylindrical surface can be determined, the pollution condition of dust pollution at the position of the cylindrical surface and the influence on the outside can be objectively reflected, and the accuracy of the pollution grade is improved.
According to one embodiment of the invention, determining the influence coefficient of the dust on the surrounding environment according to the pollution scores of the dust on each cylindrical surface comprises: the pollution of dust on each cylindrical surface is scored, and fitting is carried out on the pollution score and the third power of the radius of the radial section of each cylindrical surface, so that a fitting slope and a fitting constant term are obtained; and determining the fitting slope as an influence coefficient of the dust on the surrounding environment. For example, the slope represents the falling speed of the dust concentration, the slope is negative, the smaller the slope, the faster the falling speed of the concentration, the smaller the dust diffusion range, the larger the slope, the larger the dust diffusion range, and the slower the falling speed of the concentration, and therefore, the slope can be used as the influence coefficient of the dust on the surrounding environment.

The smaller the influence coefficient is, the faster the dust concentration is lowered, and the distance of dust diffusion is not far, whereas the larger the influence coefficient is, the slower the dust concentration is lowered, and the distance of dust diffusion is far.
For example, the wet dust removal equipment is adopted to remove dust at the maximum power under the conditions of serious pollution and far diffusion; under the condition of serious pollution and not far diffusion, adopting dry dust removing equipment to remove dust with maximum power; the wet dust removal equipment is adopted under the condition of less serious pollution and far diffusionDust removal is carried out on the power of the dust collector; under the condition of less serious pollution and short diffusion, dry dust removing equipment is adopted for +.>Is dedusted by the power of (2).
