Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the correlation technique of raise dust monitoring, usually need set up raise dust monitoring facilities inside outdoor construction place, be provided with a plurality of information acquisition units in this type of raise dust monitoring facilities usually, for example, particulate matter detecting element, image acquisition unit, wind direction wind speed acquisition unit, noise acquisition unit and positioning unit etc.. After various information, such as particulate matter concentration information, image information, wind direction information, wind speed information, noise information and positioning information, is acquired through the information acquisition units, the information is respectively sent to a management terminal of a manager of the dust emission monitoring system for display. Wherein, to the construction site that particulate matter concentration exceeds standard, can export warning on above-mentioned management terminal and remind to the suggestion managers carries out focus on this construction site. It can be seen that, above-mentioned raise dust monitoring method only shows a plurality of kinds of data that gather respectively, the information that does not gather different information acquisition units fuses the use, also do not consider the influence of other pollution sources peripheral in outer construction place to this construction place simultaneously, the condition of the raise dust monitoring wrong report of this construction place that can't avoid leading to because of other pollution sources raise dust exceed standard, the degree of accuracy of raise dust monitoring is lower, and then make managers need carry out artifical the verification to all warning that exceed standard, improve the cost of labor of raise dust control.

To this end, the present disclosure provides a raise dust monitoring method, apparatus, and system, specifically as follows:

before introducing the raise dust detection method provided by the present disclosure, an application scenario of the raise dust monitoring method is introduced, where the application scenario includes a server, the server includes a raise dust monitoring system, and the raise dust monitoring system includes at least one server and a plurality of raise dust monitoring devices. The server is in communication connection with all the dust monitoring devices arranged in a certain region (such as province, city or administrative district), can receive and store various data information reported by each dust monitoring device, and outputs alarm reminding information indicating that the concentration of particulate matters exceeds the standard in a pollution source where the dust monitoring devices are located through an output unit (such as a display or an alarm lamp).

Fig. 1 is a flowchart illustrating a raise dust monitoring method according to an exemplary embodiment, where the raise dust monitoring method is applied to a server in the application scenario, as shown in fig. 1, and the method includes:

step 101, determining whether a first pollution source is in a closed state or not under the condition that a particulate matter concentration monitoring value collected by first monitoring equipment arranged in the first pollution source exceeds a standard.

Illustratively, the particulate matter concentration monitoring value is a particulate matter number concentration value or a particulate matter mass concentration value detected by a particulate matter detection unit included in the first dust monitoring apparatus, and is performed in microgram/mn (microgram per cubic meter) or #/mn (microgram per cubic meter). The first pollution source may be an outdoor construction site, a mining site or a smoke exhaust system of a factory, and the closed state may be understood as a shutdown state of the outdoor construction site, the mining site or the factory. Specifically, in the embodiment of the disclosure, in the case that it is determined that the monitored value of the particulate matter concentration collected by the first monitoring device exceeds the standard, the alarm prompt for the event that the particulate matter concentration of the first pollution source exceeds the standard is not directly performed. But the situation that the particulate matter concentration monitoring value detected by the first monitoring equipment exceeds the standard is caused by the fact that the dust generated by other pollution sources is firstly removed from being diffused to the first pollution source before prompting. Specifically, it is first determined whether a construction site (i.e., a first pollution source) where a first monitoring device that monitors an excessive particulate matter concentration monitoring value is located is shut down in a current time period (i.e., the time period that the excessive particulate matter concentration monitoring value is monitored) and no monitorable illegal start-up behavior exists. If it is determined that the construction site is shut down in the current time period and has no monitorable illegal start-up behavior, but the monitoring value of the particulate matter concentration on the construction site exceeds the standard, it is determined that the dust emission monitoring process of the first monitoring device is influenced by other factors, and the standard exceeding reason analysis and alarm reminding processes in the following steps 102 to 104 are further performed.

And 102, under the condition that the first pollution source is determined to be in a closed state, determining m second pollution sources with the exceeding-standard particulate matter concentration events according to the wind direction information collected by the first monitoring equipment.

Wherein a second monitoring device is disposed within each of the second sources of contamination, and m is greater than or equal to 1.

For example, in the step 102, it is necessary to determine other pollution sources that may affect the first pollution source, and then analyze the influence degree of the other pollution sources on the first pollution source in the subsequent steps. Specifically, particulate matter in site dust is mainly PM10, and also includes PM2.5, and according to relevant empirical tests, the effective diffusion range of the particulate matter in urban environments is about 1 kilometer. Based on this, the position of the first pollution source can be taken as a basic point, and a range of about 1 km of a square circle can be determined according to the peripheral topography. And then, determining all pollution sources reporting the event that the concentration of the particulate matters exceeds the standard within the range as the second pollution source according to the positioning information reported by each dust emission monitoring device and the event that the concentration of the particulate matters exceeds the standard. It should be noted that, the above-mentioned "the second pollution source of the event that the particulate matter concentration exceeds the standard" may be understood as a pollution source that has excluded misjudgment or misinformation and the like and has been determined by manual review by a manager that the real condition that the particulate matter concentration exceeds the standard exists.

103, determining a particulate matter concentration diffusion value of the particulate matter generated by the second pollution source diffusing to the first pollution source according to the positioning information of the first monitoring device and the second monitoring device, and the particulate matter exceeding monitoring value and the wind speed information acquired by the second monitoring device.

For example, the influence degree of the other pollution sources on the first pollution source can be understood as a process that particulate matters generated by the pollution sources with the excessive particulate matter concentration diffuse with the atmosphere through a preset particulate matter diffusion model, so as to determine an estimated value of the particulate matter concentration of an area (i.e., the particulate matter concentration diffusion value) in which the first pollution source is located when the particulate matters generated by the pollution sources with the excessive particulate matter concentration diffuse with the atmosphere. When the particulate diffusion simulation and the particulate concentration diffusion value analysis are performed by the particulate diffusion model, the particulate concentration at the first pollution source itself is set to 0. The particulate matter exceeding monitoring value can be a particulate matter concentration monitoring value collected by the second monitoring device when the particulate matter concentration exceeding event of the second pollution source is determined.

And 104, comparing the particulate matter concentration diffusion value with the particulate matter concentration monitoring value to determine whether to output reminding information for indicating that the particulate matter concentration of the first pollution source exceeds the standard.

Illustratively, a particulate matter concentration monitoring value monitored by a first monitoring device in real time is compared with an estimated particulate matter concentration diffusion value, and according to the difference between the particulate matter concentration monitoring value and the estimated particulate matter concentration diffusion value, whether the condition that the particulate matter concentration monitoring value at the first pollution source reported by the first monitoring device exceeds the standard is caused by the first pollution source or caused by the particulate matter diffusion of other pollution sources can be determined, so that whether to output the reminding information is determined. The reminding information is used for reminding a manager of the raise dust monitoring system to manually observe, or the reminding information can be stored in a database of the server to be subjected to subsequent supervision and investigation by the manager.

In summary, the technical scheme provided by the embodiment of the disclosure can determine whether the exceeding particulate matter concentration monitoring value is caused by the influence of other pollution sources by combining the wind direction and the wind speed at the pollution source to be detected, and further determine whether to output the exceeding reminding aiming at the pollution source to be detected, so that the accuracy of dust monitoring is improved, and the labor cost of dust monitoring is reduced.

Fig. 2 is a flow chart of a method for determining the status of a pollution source according to fig. 1, wherein the step 101 may include:

step 1011, determining whether the first pollution source has an illegal construction behavior according to a pre-stored construction schedule and the image information acquired by the first monitoring device.

The construction schedule is used for recording the construction state of each pollution source provided with monitoring equipment in each preset time period in the preset area.

Illustratively, this step 1011 may comprise: determining whether the first pollution source is in a shutdown state or not according to a pre-stored construction schedule; and under the condition that the first pollution source is determined to be in a shutdown state, image recognition is carried out on the image information collected by the first monitoring equipment so as to determine whether the construction behavior exists at the first pollution source. Specifically, for a construction site provided with a raise dust monitoring device, each construction site corresponds to a construction schedule, and a manager of the construction site is responsible for reporting the construction state to relevant management departments periodically to update the construction schedule. The construction schedule is composed of a plurality of time periods and construction states corresponding to each time period. The monitoring value of the particulate matter concentration received by the server corresponds to acquisition time, and the construction state of the construction site can be determined when the monitoring value of the particulate matter concentration is acquired according to the inclusion relation between the acquisition time and each time period in the construction schedule. Specifically, if the server receives a particulate matter concentration monitoring value and determines that the particulate matter concentration monitoring value exceeds the standard, a timestamp corresponding to the particulate matter concentration monitoring value is obtained first and used as acquisition time. And then, determining the time period of the acquisition time, and further determining the construction state corresponding to the time period.

For example, after determining that the construction site is in a shutdown state according to the construction schedule, it is also necessary to consider the situation that the construction site still violates the start of work after reporting the shutdown. Specifically, the image information of the construction site can be acquired through an image acquisition unit (i.e., a camera) arranged in the first monitoring device, and then the image information is subjected to image recognition, whether a large number of people walk in the construction site within the acquisition time is determined, and then whether the construction site is illegally worked is judged. Specifically, the face recognition may be performed on one or more frames of pictures in the image information and the number of faces may be calculated, and/or a moving object in the pictures may be recognized and the number of moving objects may be calculated. If the number of the faces or the number of the moving objects exceeds the preset number, the fact that the construction site is out of operation after reporting shutdown can be determined.

In step 1012, in the case that it is determined that the first pollution source does not have the illegal construction behavior, it is determined that the first pollution source is in a closed state.

Illustratively, it should be noted that the shutdown status determined in

steps

1011 and 1012 is only the shutdown status of the monitorable layer. In actual construction, there are cases where monitoring is impossible, for example, a construction party does not follow a construction schedule and shields or intentionally leaves a camera monitoring range. Therefore, it is practical to continue to perform the above steps 102 to 104 after

steps

1011 and 1012. Specifically, the reminding information output in step 104 can assist the manager in determining the construction violation behavior under the unmonitored condition.

Fig. 3 is a flow chart of a method for determining a source of a relevant contamination according to fig. 1, wherein step 102, as shown in fig. 3, may include:

step 1021, determining a target partition from a plurality of preset partitions corresponding to the first pollution source according to the wind direction information.

The preset partitions are fan-shaped partitions obtained by equally dividing a circular area which takes the first pollution source as a circle center and takes a preset length as a radius.

Illustratively, fig. 4 is a schematic diagram illustrating a method for determining a related pollution source according to an exemplary embodiment, as shown in fig. 4, a point a represents the first pollution source, a circular area with a preset length (e.g., 1 km) as a radius and a center of the point a is determined first, and the circular area is further divided into A, B, C, D, E, F, G sectors and H sectors, each of which is one of the preset sectors. In addition, an arrow p passing through a point a in fig. 4 is used to represent the wind direction information, and if the wind direction at the first pollution source is as shown by the arrow p when an excessive particulate matter concentration monitoring value is monitored, the partition a is determined as the target partition. It is to be understood that the predetermined partition may also be a plurality of rectangular partitions obtained by equally dividing a square area with a predetermined length as a side length around the first pollution source. Or, the preset partition may be a plurality of arbitrary-shaped partitions of different sizes obtained by dividing an area having an arbitrary shape determined based on the position of the first pollution source, the distribution of other pollution sources, and the topographic features of the city itself. For example, if there are several tall buildings or forests between partition B and the first pollution source represented by point a, partition B may be directly excluded, i.e., the above-mentioned several predetermined partitions only include seven sectorial partitions A, C, D, E, F, G and H.

And step 1022, regarding each pollution source with the excessive particulate matter concentration event in the target partition as the second pollution source.

For example, after determining the target partition, the dust monitoring devices in the target partition may be determined according to the positioning information uploaded by each dust monitoring device. As shown in fig. 3, the partition a contains three pollution sources, b, c and d, and each pollution source is provided with a dust monitoring device. And then, whether the dust monitoring equipment arranged in the three pollution sources b, c and d reports the dust exceeding event (or called the particle concentration exceeding event) at the moment of the exceeding particle concentration monitoring value collected by the first dust monitoring equipment can be determined, the dust monitoring equipment reporting the dust exceeding event is used as second dust monitoring equipment, and the pollution source where the second dust monitoring equipment is located is used as the second pollution source. For example, in the three pollution sources b, c and d, if the dust monitoring devices corresponding to the pollution source b and the pollution source d report an event that the dust exceeds the standard at the moment of the monitoring value of the concentration of the exceeding particulate matter collected by the first dust monitoring device, the pollution source b and the pollution source d are determined to be the second pollution source, and the pollution source c is not the second pollution source.

Fig. 5 is a flow chart of a method for determining a particulate matter concentration spread value according to fig. 1, wherein step 103, as shown in fig. 5, may include:

step 1031, determining the position information of the first monitoring device relative to the second monitoring device according to the positioning information.

Wherein the position information is the first monitorThree-dimensional coordinates of position of equipment to be tested in target coordinate system

The target coordinate system is a three-dimensional coordinate system established by taking the position of the second monitoring device as an origin.

For example, the above-mentioned positioning information may be latitude and longitude information and altitude information. After acquiring the longitude and latitude information of the two devices, the longitude and latitude information of the second monitoring device is taken as an origin, and the longitude and latitude information of the first monitoring device is subjected to coordinate conversion, so that the three-dimensional coordinate can be determined

U and v in (1). The difference value of the altitude information of the first monitoring equipment subtracted by the altitude information of the second monitoring equipment is the three-dimensional coordinate

W in (1).

Illustratively, FIG. 6 is a schematic illustration of a particulate matter diffusion state shown according to an exemplary embodiment, the three-dimensional coordinate system shown in FIG. 6 being the target coordinate system described above. In the target coordinate system, the point o is a position (i.e., a position of the second pollution source) indicated by the positioning information reported by the second monitoring device, and three coordinate axes of the target coordinate system are respectively used for representing three directions of particulate matter diffusion. Specifically, the x-axis represents a diffusion direction from the second pollution source to the first pollution source, the y-axis represents a diffusion direction toward both sides of the x-axis, and the z-axis represents a diffusion direction perpendicular to the ground. The result of the diffusion of particulate matter produced by this second source of pollution with the wind direction can be seen in fig. 5. Wherein, setting the wind direction as positive x direction, the diffusion range of the particles generated by the second pollution source can be expressed as 5 diffusion layers according to the estimated different particle concentration diffusion values. The difference in the particulate matter concentration at each position point in each diffusion layer is smaller than a preset difference, and the particulate matter concentration at each position in each diffusion layer can be considered to be approximate, and the particulate matter concentration in the diffusion layer is characterized by the average value of the diffusion of the particulate matter concentration at a plurality of positions in the whole diffusion layer. It is understood that the average value of the diffusion of the particulate matter concentration in the diffusion layer 1 of reference numeral 1 is larger than the average value of the diffusion of the particulate matter concentration in the diffusion layer 2 of reference numeral 2 in the figure, and so on. The average value of the diffusion of the particulate matter concentration in each of the 1 st diffusion layer to the 5 th diffusion layer is smaller than the particulate matter concentration monitoring value of the second monitoring device.

And 1032, determining the generation amount of the particulate matters of the second pollution source according to the excessive particulate matter monitoring value collected by the second monitoring equipment.

Wherein the particulate matter generation amount is the particulate matter generation amount of the second pollution source in units of μ g/s (micrograms per second).

For example, after the second pollution source is determined to have the event that the concentration of the particulate matter exceeds the standard and the monitoring value of the second monitoring device is sent to the server, the particulate matter generation amount can be directly determined according to the particulate matter exceeding monitoring value and the emission flow for quantitatively emitting the particulate matter of the second pollution source.

In another embodiment, the particulate generation amount can be determined based on the excessive particulate monitoring value and the estimated particulate influence range (the range is used for representing the volume influenced by the particulate) aiming at a second pollution source which does not quantitatively release the particulate, such as a construction site or a mining site. According to data collection of a plurality of construction sites or mining sites, the height of the PM10 particulate matter raised by construction activities is usually 10 to 20m (meters) in a windless environment, and the effective construction area of the construction site or mining site is usually 0.5 times the total area of the site. The effective construction area is a main site where particulate matter is generated in a construction site or a mining site, for example, an earth-moving work site or a truck-driving road, etc. The aforementioned particulate matter influence range may be the product of the effective construction area of the construction site or mining site and the aforementioned diffusion height. Based on the above, after the occurrence of the event that the concentration of the particulate matters exceeds the standard is determined to occur in the second pollution source and the monitoring value of the second monitoring equipment is sent to the server, the server obtains the total construction area of the second pollution source, which is 5000 square meters, the monitoring value that the particulate matters exceed the standard and the particulate matters concentration monitoring value collected at any moment before the event that the concentration of the particulate matters exceeds the standard reported by the second pollution source, wherein the particulate matters monitoring value is collected at the first moment and the particulate matters concentration monitoring value is collected at the second moment; firstly, calculating a difference value between a particulate matter standard exceeding monitoring value and a particulate matter concentration monitoring value, and calculating a quotient of the difference value divided by a target time length, wherein the quotient is used as the particulate matter production of the second pollution source in unit time and unit volume, and the target time length is the time length between the first time and the second time; secondly, multiplying the total construction area of 5000 square meters by 0.5 and then multiplying by the preset diffusion height of 10m to obtain 25000 m of particulate matter influence range for carrying out the cultivation; the amount of particulate matter produced by the second source of contamination per unit of time may be obtained by multiplying the amount of particulate matter produced by the second source of contamination per unit of time by the range of particulate matter impact 25000 m.

And 1033, taking the position information, the particulate matter generation amount and the wind speed information as the input of a preset particulate matter diffusion equation to obtain the particulate matter concentration diffusion value output by the particulate matter diffusion equation.

Illustratively, the second pollution source is located at the origin of coordinates o, and the average wind direction is parallel to and co-directional with the x-axis. It is assumed that the particles generated by the second pollution source are spread in free space without any obstacles and do not take into account the effect of rebound of the particles after touchdown caused by the underlying surface (i.e., the ground). The main diffusion direction of the diffusion of the particulate matter in the atmosphere is along the x-axis direction, and exhibits a two-dimensional normal distribution in both the y-axis and z-axis directions. When the random variables of the two coordinate directions are independent, the distribution density is the product of one-dimensional normal distribution density functions of each coordinate direction. The particle diffusion equation can be expressed by the following formula (1) after reasoning:

（1），

wherein u is the coordinate value of the x axis in the position information, v is the coordinate value of the y axis in the position information, and w isThe z-axis coordinate value in the position information,

in the above-mentioned position information

The particulate matter concentration diffusion value is expressed in mu g/m, q is the particulate matter generation amount and is expressed in mu g/s (microgram per second), k is the wind speed information collected by the second monitoring equipment and is expressed in m/s (meter per second),

the diffusion parameter of the particulate matter in the y-axis direction of the target coordinate system is preset,

for the preset diffusion parameter of the particulate matter in the z-axis direction of the target coordinate system,

and

the units of (A) are m (meters).

The operation of the system is illustratively,

and

the specific numerical value of the method is determined according to the technical method for establishing the local atmospheric pollutant emission standard (GB 384091) in China. Specifically, in the technical method for making the local atmospheric pollutant discharge standard, the atmospheric stability is divided into 6 levels, which are determined according to the local average wind speed and the current solar radiation level. The technical method for establishing the local atmospheric pollutant emission standard also provides a corresponding relation table between each atmospheric stability degree grade, diffusion coefficient and downwind distance. The pairThe corresponding relation table comprises: to is directed at

A table of values of the expression coefficients of the power function of the lateral diffusion parameter, and, for

The vertical diffusion parameter power function expression coefficient value table. The diffusion parameter can be determined by inquiring the corresponding relation table according to the atmospheric stability degree grade and the downwind distance

And

. Additionally, the downwind distance is a distance between the first pollution source and the second pollution source. In the technical method for establishing the local atmospheric pollutant emission standard, the downwind distance is pointed out in the above

The coefficient value table of the lateral diffusion parameter power function expression is represented as follows: less than or equal to 1 kilometer and greater than 1 kilometer; in addition, the above-mentioned aim at

In the table of the coefficient of the power function expression of the transverse diffusion parameter, according to the difference of the atmospheric temperature degree, the downwind distance is represented as: 0 to 300 m, 300 to 500 m, 500 m or more, 0 to 1000 m, 0 to 2000 m, 1000 to 10000 m, and the like.

Fig. 7 is a flow chart of another dust monitoring method according to fig. 1, and as shown in fig. 7, the step 104 may include: step 1041, or step 1042 and step 1043.

Step 1041, determining to output the reminding information when m is equal to 1 and the difference between the particulate matter concentration diffusion value and the particulate matter concentration monitoring value is larger than a preset difference.

For example, the excessive concentration of particulate matter at the first pollution source can be considered to be caused by the superposition of the dust of other pollution sources diffused thereto and the dust generated by the first pollution source itself. Therefore, it is assumed that the monitored particulate matter concentration value is greater than the diffused particulate matter concentration value, and the difference may be a difference obtained by subtracting the diffused particulate matter concentration value from the monitored particulate matter concentration value. From this difference it can be determined which of the dust emissions of the other pollution sources that have diffused there has a greater influence than the dust emissions of the first pollution source itself. If the difference between the particulate matter concentration diffusion value and the particulate matter concentration monitoring value (the difference is a positive number and can be understood as an absolute value of the difference) is less than or equal to the preset difference, the dust generated by the first pollution source can be considered to be very little, and the condition that the particulate matter concentration monitoring value exceeds the standard is influenced by the second pollution source is further determined; if the difference between the particulate matter concentration diffusion value and the particulate matter concentration monitoring value is larger than the preset difference, the judgment of the particulate matter concentration of the first pollution source can be considered to be influenced by the dust generated by the first pollution source, and the fact that the particulate matter concentration monitoring value exceeds the standard is determined to be caused by the reason of the first pollution source.

Specifically, according to the above step 102, the number of the second pollution sources may be 1 or more. Under the condition that the number m of the second pollution sources is 1, the difference value between the particulate matter concentration diffusion value and the particulate matter concentration monitoring value can be directly compared with the preset difference value, and under the condition that the difference value between the particulate matter concentration diffusion value and the particulate matter concentration monitoring value is smaller than or equal to the preset difference value, the particulate matter concentration monitoring value exceeding the standard is determined to be influenced by the second pollution sources, and no reminding information is output. Otherwise, determining that the exceeding of the monitoring value of the particulate matter concentration is caused by the reason of the first pollution source, and outputting the reminding information.

And 1042, acquiring m sum values of the particulate matter concentration diffusion values under the condition that m is greater than 1.

And 1043, determining to output the reminding information when the difference between the sum and the monitoring value of the particulate matter concentration is larger than the preset difference.

For example, in the case that the number m of the second pollution sources is greater than 1, it can be considered that the particulate matters of the second pollution sources are all diffused to the first pollution source, so the overall influence of the particulate matters of the second pollution sources on the first pollution source needs to be considered. Specifically, a plurality of second pollution sources can be superposed relative to the particulate matter concentration diffusion value of the first pollution source, the difference between the superposed sum and the particulate matter concentration monitoring value is compared with the preset difference, and under the condition that the difference between the sum and the particulate matter concentration monitoring value is smaller than or equal to the preset difference, the particulate matter concentration monitoring value exceeding the standard is determined to be influenced by the plurality of second pollution sources, and no reminding information is output. Otherwise, determining that the exceeding of the monitoring value of the particulate matter concentration is caused by the reason of the first pollution source, and outputting the reminding information.

In addition, in the case that it is determined according to step 1041, or step 1042 and step 1043 that the monitored value of the particulate matter concentration exceeds the standard and is affected by one or more second pollution sources, a name or a code corresponding to the second pollution source that affects the monitored value of the particulate matter concentration at the first pollution source may be output to assist the subsequent management work of the administrator.

Fig. 8 is a flow chart of another dust monitoring method according to fig. 1, and as shown in fig. 8, before the step 101, the method may further include:

and 105, determining whether the particulate matter concentration monitoring value exceeds the standard or not according to the particulate matter concentration basic value acquired by the state control site and the wind direction information acquired by the first monitoring equipment.

Illustratively, the national control site is a government environment monitoring central station, for example, a Chinese environment monitoring central station, and environment monitoring sites are arranged in various detection areas. Each monitored region, for example, a province, a city or an administrative district, is usually provided with a plurality of nationally controlled sites. The domestic control site is typically located in a location within the monitoring area that is well ventilated and not susceptible to industrial sources of pollution (e.g., mine or construction site dusting, factory exhaust emissions, etc.). The environmental index including the particulate matter concentration basic value reported by the national control site can be considered as a basic environmental index of a local area under the condition of no industrial pollution. Taking the china environmental monitoring central station as an example, the position and the detection data of each country control station can be obtained by applying a data interface to the china environmental monitoring central station, or by capturing data issued by the china environmental monitoring central station on a public platform (for example, an application program "air quality issue" of the china environmental monitoring central station), and the like.

FIG. 9 is a flowchart of a method for determining whether a monitored value of particulate matter concentration exceeds a threshold value shown in FIG. 8. As shown in FIG. 9, step 105 may include:

and 1051, determining n target national control sites within a preset range.

The preset range is a circular area which takes the first pollution source as a circle center and takes a preset distance as a radius.

For example, the preset range may be set to an area 3 km away from the first pollution source square circle, and the target domestic control site is all domestic control sites within 3 km away from the first pollution source square circle. If no country control station is located within 3 km, the selection range is widened, for example, the preset range can be sequentially widened to 5 km and 8 km until 10 km, that is, all country control stations within 5 km, 8 km and 10 km are sequentially searched to serve as target country control stations.

In another possible embodiment, if the number of the selectable country control stations in the preset range (including the widened preset range) is large (for example, larger than a certain preset value), a part of country control stations may be screened according to the wind direction. Specifically, the country control site located downwind of the first monitoring device (determined according to the wind direction information reported by the first monitoring device) may be deleted, and the remaining country control sites may be used as target country control sites. Then, the process of calculating the average value of the particulate matter concentration in step 1052 is performed to improve the accuracy of the standard value. In this case, the step 1051 may include: determining all national control sites within the preset range; and deleting the national control sites in the downwind direction of the first pollution source from all the national control sites according to the wind direction information acquired by the first monitoring equipment so as to acquire the n target national control sites.

And 1052, acquiring the average value of the particle concentration basic values of the n target national control sites.

And 1053, determining the standard exceeding coefficient corresponding to the average particulate matter concentration value according to a preset coefficient corresponding table.

Wherein, the coefficient corresponding table is used for representing the corresponding relation between the average value of the particulate matter concentration and the standard exceeding coefficient.

And 1054, calculating the product of the average value of the particulate matter concentration and the standard exceeding coefficient as a standard value.

And 1055, if the monitoring value of the concentration of the particulate matter collected by the first monitoring device is larger than the standard value, determining that the monitoring value of the concentration of the particulate matter collected by the first monitoring device exceeds the standard.

For example, each national control site is provided with a particulate matter monitoring device, and the particulate matter concentration basic value is a particulate matter concentration value detected by the particulate matter monitoring device arranged at each national control site. When determining whether the monitored value of the particulate matter concentration at the pollution source exceeds the standard, the basis value of the particulate matter concentration of one or more national control stations within the preset range at the pollution source can be searched, and the average value of the particulate matter concentration (the average value can be a mathematical average value or a weighted average value calculated by adding weights according to the distance and the position) can be calculated, and the average value can be regarded as the background value of the local particulate matter concentration. It can be understood that the dust emission monitoring process in the embodiment of the present disclosure is a process of monitoring the dust emission generation amount of the pollution source, and therefore, the particulate matter generated by the pollution source needs to be evaluated on the basis of the air condition of the area where the pollution source is located, and therefore, the product of the batch average value and the preset standard exceeding coefficient is the standard value for standard exceeding evaluation.

Illustratively, the coefficient correspondence table is a correspondence table determined according to experimental data based on dust emission monitoring, the influence degree of the dust emission generation amount on the environment and human activities, and the perception degree of human beings on the total concentration of particulate matters. For example, when the local particulate matter concentration average value is 40 (microgram/cubic meter), according to the influence degree of the dust generation amount on the environment and human activities, when the particulate matter concentration monitoring value exceeds 3 times of the particulate matter concentration average value, the particulate matter concentration of the pollution source is determined to be out of standard; when the local mean value of the particulate matter concentration itself is at a higher value, for example 260, the high monitoring value has a lesser influence on the environment and on human activities, and it is therefore set to determine that the particulate matter concentration of the pollution source is out of limits when the monitored value of the particulate matter concentration exceeds 1.5 of the mean value of the particulate matter concentration. Based on this, in the coefficient correspondence table, the higher the value of the particulate matter concentration average value is, the smaller the ratio (i.e., the superstandard coefficient) of the standard value to the particulate matter concentration average value is. In one disclosed embodiment, the coefficient mapping table may be shown in table 1 below:

for example, in the case that the average value of the particulate matter concentration exceeds 300 (micrograms/cubic meter), it can be determined that the city weather escort exceeds the standard, and the monitoring value of the particulate matter concentration of the construction site is not evaluated.

In summary, the raise dust monitoring method provided by the embodiment of the disclosure can determine whether the exceeding particulate matter concentration monitoring value is caused by being influenced by other pollution sources by combining the wind direction and the wind speed at the pollution source to be detected, and further determine whether to output the exceeding reminding aiming at the pollution source to be detected, so that the accuracy of raise dust monitoring is improved, and the labor cost of raise dust monitoring is reduced.
