The sources of fine dust in construction and industrial sites are mainly scattering dust from direct dust generating work such as excavation work, combustion work, and storage, and fine dust from vehicles due to transport work. Accordingly, the fine dust generating source information identification unit 223 derives fine dust weighting factors by identifying the number of operating units, operating hours, and operating locations of equipment in the field, and the correlation between fine dust generation and field work through fine dust weighting factors information on the source of fine dust can be grasped.

It is automatically activated through a relay connected to the wireless communication terminal to spray water.

The fine dust integrated management system 200 according to an embodiment may perform the fine dust integrated management method. The fine dust integrated management method implemented through the fine dust integrated management system 200 according to an embodiment is to collect fine dust information and fine dust information from a specific outdoor site in the fine dust status monitoring unit 210. Step, and the fine dust generation cause analysis unit 220 estimates the contribution of fine dust from the field using the weather fine dust information and the fine dust information from the field, and identifies the correlation between the generation of fine dust and field work to determine the fine dust It may be made including the step of identifying the source information of the.

In addition, when the fine dust generation control unit 230 exceeds a preset management standard based on the contribution of on-site fine dust, a notification message is sent to the manager terminal, or fine dust is generated according to the fine dust source information The method may further include spraying water through a watering nozzle to an area or facility.

Hereinafter, the fine dust integrated management system 200 according to an embodiment will be described in more detail as an example.

The fine dust status monitoring unit 210 may collect data in the following two ways in order to use it as data for analyzing the causes of fine dust in construction and industrial sites and identifying the current status.

The first collected information is public data in the meteorological field, which corresponds to “weather fine dust information (a)” in the area. “Weather fine dust information (a)” can be judged to be mostly affected by weather phenomena on the Korean Peninsula and fine dust from China. "Meteorological fine dust information (a)" provides real-time nationwide fine dust status information from the Ministry of Environment or the Environment Management Corporation, and opens API (Application Programming) Interface) and can be used as basic fine dust status data for the area.

The second collection information can be collected in real time by installing fine dust sensors at construction and industrial sites, and "field fine dust information (b)". "Site fine dust information (b)" is the fine dust concentration directly reflecting the impact of construction and industrial site work activities. The location of the fine dust sensor to be installed is also one of the information to be collected. For effective monitoring, it is effective to distribute the sensors throughout the site rather than centrally deploying them in one area of the site.

The point of analyzing the current state of fine dust is to identify the causes of fine dust. This is because it is possible to minimize the occurrence of fine dust by managing it only when the cause of the occurrence of fine dust is identified. Accordingly, a method of analyzing the cause of the fine dust through the fine dust generating cause analysis unit 220 is as follows.

First, the fine dust generation cause analysis unit 220 may determine the "contribution degree (d) of fine dust from the field" through the comparison of weather information, and may be expressed as follows.

[Equation 1]

"Contribution of fine dust from the field (d)" = "Meteorological fine dust information (a)" - "Information about fine dust from the field (b)"

The contribution (d) of fine dust from the field can be estimated by comparing the local weather information and the absolute value of fine dust at the site through big data analysis by period.

As a result of the analysis, if the contribution (d) of fine dust from the field is insignificant, it can be judged that the site generates little fine dust and is highly dependent on the influence of the weather on the Korean Peninsula. In this case, it is necessary to minimize activities and expenses for fine dust control. On the other hand, if the contribution (d) of fine dust from the field shows a meaningful difference value, it can be judged that the concentration of fine dust due to the work activities of the field is increasing. In this case, since the occurrence of fine dust in the field is clear, it is necessary to carry out activities to suppress fine dust.

Second, the fine dust generation cause analysis unit 220 may improve the precision of "fine dust information from the field (b)" by comparing the position of the sensor value in the field.

If the work area of the site is wide, there may be cases where several fine dust sensors are installed and observed. In this case, it is possible to improve the precision of calculating the contribution (d) of fine dust from the field by grasping the location information of the fine dust sensor.

5 is a diagram illustrating an example of a field area for dividing an installation location of a fine dust sensor according to an embodiment.

It is desirable to install the fine dust sensor dispersedly in the field rather than concentratedly installing it as much as possible. As shown in (a) of FIG. 5, for example, when there are two fine dust sensors, the site is divided into left and right or east and west, and as shown in (b), when there are three or more fine dust sensors, the site is squared It can be used as useful information by determining where it is located in the 1st, 2nd, 3rd, and 4th quartiles in the clockwise direction.

The concentration of fine dust at construction and industrial sites may vary depending on the direction the wind blows (ie, the direction of the wind). The fine dust concentration at the point where the wind first blows on the construction site will be similar to “weather fine dust information (a)”, and the fine dust concentration at the end point passing through the site is “site fine dust information (b)” will represent the most

Accordingly, in the above-mentioned "contribution degree of on-site fine dust (d)", "field fine dust information (b)" is a fine dust sensor, two Alternatively, if there are three or more, the precision of “fine dust information from the field (b)” can be improved by citing the sensor value opposite the wind direction. For example, if there are two fine dust sensors and the wind blows from west to east, the precision of “field fine dust information (b)” is calculated using the sensor value of the fine dust sensor located in the east, which is the sensor value opposite to the wind direction. can enhance

Third, the fine dust generation cause analysis unit 220 may determine "fine dust generation source information (c)" of the field.

The sources of fine dust in construction and industrial sites are mainly scattering dust from direct dust generating work such as excavation work, combustion work, and storage, and fine dust from vehicles due to transport work. If the operation time, number of operation, and operation location of these equipment are identified and converted into data, the correlation between the generation of fine dust and these operations can be grasped, and it can be expressed as the following equation. Here, the movable position means whether the equipment is located in the field.

[Equation 2]

Fine dust weighting factor (e) = number of operating units x operating time x operating position

To understand this, work using the Geo Fence function by installing a location tracking terminal with a built-in GPS (Global Positioning System) in the excavation work vehicle or direct dust generating equipment such as combustion equipment and storage, facilities and transport vehicles. It is possible to derive fine dust weighting factors by identifying the number and operating hours of vehicles operated within the zone.

Fourth, the fine dust generation cause analysis unit 220 may determine the amount of moisture in the field air.

The amount of moisture (humidity) in the air at the site affects the spread of fine dust. A hygrometer installed at the site can determine the amount of moisture in the air in real time, and the correlation of this on the concentration of fine dust in the site can be understood through big data. Since the conditions of the main soil and land distributed in the construction and industrial sites may vary from site to site, analyzing big data can determine what kind of humidity shows the maximum concentration of fine dust at each site.

When the moisture content in the air reaches a level that affects the spread of fine dust concentration, the fine dust integrated management system provides moisture content information to the manager and can immediately instruct the control unit to operate the moisture supply mechanism. The moisture provision mechanism can spray a watering nozzle for humidity control in the dusty area. There are two types of this spraying nozzle: the air spraying method and the local spraying method, which intensively sprays fine dust generating facilities such as excavators, crushers, and belt conveyors.

6 is a view showing a water spray system for suppressing fine dust according to an embodiment.

Referring to FIG. 6 , a water spray system 600 for suppressing fine dust according to an embodiment includes a fine dust sensor 610 , a server 620 , a communication network 630 , a GPS wireless communication terminal 640 , and a water spray nozzle. 650 may be included. As the sensor value measured by the fine dust sensor 610 is transmitted to the server 620 , the server 620 may determine whether the concentration of fine dust exceeds the management reference value. Here, when the concentration of fine dust exceeds the management reference value, the server 620 may transmit the excess situation information to the GPS wireless communication terminal 640 through the communication network 630 . Here, the GPS wireless communication terminal 640 may include a manager terminal and the like. The GPS wireless communication terminal 640 may lower the concentration of fine dust by operating a relay upon receiving a terminal signal and spraying water through the watering nozzle 650 .

Hereinafter, a control method and a water spray system for suppressing fine dust using the fine dust generation control unit 230 will be described in more detail as an example.

The fine dust generation control unit 230 may send a message to the manager terminal when the concentration of fine dust exceeds the management reference value through the analysis of the fine dust status. For example, when the concentration of fine dust exceeds the management standard, a warning message can be sent through the administrator's smartphone and PC e-mail. Here, the terminal is not only a smart phone, but also a mobile phone, a laptop computer, a digital broadcasting terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), a navigation system, and a slate PC. ), a tablet PC, an ultrabook, a digital TV, a desktop computer, and the like.

Also, when the concentration of fine dust exceeds the management reference value, the fine dust generation control unit 230 may send a message for increasing the amount of water sprayed to the terminal of the water sprinkler driver. For example, when the concentration of fine dust exceeds the management standard, the sprinkler driver's smartphone can be instructed to increase the amount of water sprayed through SMS and an app. Here, the sprinkler vehicle is equipped with a GPS vehicle control terminal, so the movement flow is identified, and the operation results before and after exceeding the fine dust standard are expressed in driving time and distance, so that the result of active watering is automatically known. can make it happen

A water spray system that sprays water particles like a mist can be installed along an area where the source of fine dust is concentrated. When the concentration of fine dust exceeds the management standard, the server of the automatic management system issues a command to the control unit to activate the water spray system. By spraying water into the air, the moisture content is increased to absorb fine dust and then settle.

The water spray system may be mounted on a vehicle or the like and configured as a mobile type. In the case of a mobile water spray system, a spray nozzle can be installed on a vehicle equipped with a water tank, such as a watering vehicle, so that fine water spray can be sprayed along the fine dust generation movement.

In addition, an automatic water spray system can be installed on fine dust generating equipment. The automatic water spray system installed in an excavation vehicle, combustion facility, or fine dust generating equipment consists of a GPS wireless communication terminal, a water tank and a watering nozzle. In the case of an excavation vehicle, the watering nozzle is installed on a boom equipped with a bucket, and the water tank is installed at the rear of the vehicle. In the case of a combustion facility, a water spray nozzle is installed in a smoke exhaust facility, and in the case of a storage facility, a storage facility is installed. The fine dust generation control unit 230 transmits information through a GPS wireless communication terminal mounted on vehicles and facilities when the concentration of fine dust exceeds the management standard, and executes a program to automatically operate through a relay connected to the GPS wireless communication terminal. can be set via

The fine dust monitoring notification method UI (User Interface) will be described below.

It means fine dust below.

Table 2 shows a fine dust concentration expression method according to an embodiment. Here, it can be used as a vertical dividing line to easily recognize the concentration.

[Table 2]

As shown in Table 3, as the fine dust concentration expression method, in addition to the vertical dividing line, numbers, symbols, specific character strings, and other design work (eg, images, etc.) to which a division function is assigned can be used. In addition, by using a different color for each step divided by the vertical dividing line, the density may be displayed separately. That is, different numbers/symbols/strings/design works/colors may be used depending on the density, and different numbers/symbols/strings/design works/colors may be mapped for each density range.

Accordingly, in the embodiment, the degree of density expressed through the table may be displayed by dividing it with a vertical dividing line, a number, a symbol, an image, a color, or a predetermined character string.

[Table 3]

Referring to Tables 2 and 3, when a concentration expression number is represented by a plurality of vertical dividing lines, a change in concentration can be easily observed without using a separate chart. In this case, the number and shape of the vertical dividing line may be variously determined. Here, since the concentration classification consists of 4 levels (good, average, bad, very bad), it is expressed in 4 levels. As described above, according to the embodiments, it is possible to analyze the causes and effects of fine dust at a construction site where generation of fine dust is inevitable, and automatically suppress the generation, thereby minimizing environmental pollution caused by fine dust in the process of construction and industrial activities. .
