Due to recent climate change, weather, such as temperature and rainfall, has increased in each region, and the frequency of occurrence of anomalies is also increasing. Therefore, fixed stations of the prior art cannot cope with abnormal climates.

In addition, environmental pollution caused by fine dust, including air pollutants, a by-product of industrialization, is a serious situation. Fine dust, crushing, screening of solid or liquid substances or substances suspended in gaseous media such as dust, particulate, aerosol, fume, soot, etc. It is a fine material in the solid or liquid phase that occurs during mechanical treatment such as sedimentation or combustion, synthesis, and decomposition. Particulate matter having a particle diameter of 10 μm or less is called PM10, and particulate matter having a particle diameter of 2.5 μm or less is called PM2.5 and is called ultrafine dust. Since such fine dust also continuously increases and affects people's health, there is a high need to observe and deal with the pollution level of fine dust in the air early.

Accordingly, in order to collect environmental information in the atmosphere and analyze the collected data to present a predictive and preemptive countermeasure, high-resolution environmental monitoring is essential.

However, in the case of the above-mentioned conventional technologies, observations from a fixed station with a low installation density are used due to constraints due to manpower conditions and operating costs, so that a wide range of areas can be caused by non-uniform spatial distribution and non-uniform observation density. It is not possible to perform uniform environment integrated monitoring, and as a result, the measured environmental information is inconsistent with the actual environmental information of the local area inside the environment monitoring target area, and thus has a limitation that the spatial and temporal resolution of the observed environmental information is deteriorated.

In addition, the environmental information collected using the environmental monitoring network composed of fixed stations of the prior art has different results depending on the research and analysis organizations such as the Ministry of Land, Infrastructure and Transport, the Ministry of Environment, and the Korea Environmental Agency, and it is not easy to properly deal with the environment. Has a problem

In addition, when attempting to compensate for the problem of the environmental monitoring network composed of fixed stations of the prior art, and observing environmental information, it is impossible to perform systematic environmental monitoring because it determines the monitoring area and monitoring cycle based on user experience and subjective judgment. Has a problem

The fine dust sensor unit 220 generates fine dust measurement information including the size and concentration of fine dust contained in the air to be measured by detecting the scattered light by irradiating the light after sucking the air to be measured. It is configured to output to the control unit 250.

5 is a view showing a fine dust measurement error during movement of the fine dust sensor unit 220 according to an embodiment of the present invention.

The measurement of the fine dust of the fine dust sensor unit 210 to which the light scattering method is applied in the stopped state is measured as C _PM10 = f (Q ₀ ) as shown in FIG. 5 (a) for the fine dust of _PM10 . Here, C _PM10 represents the concentration of fine dust, Q ₀ represents the flow rate sucked through the pump unit 221 in the stopped state, and f represents a functional formula converted to a concentration.

It is configured to perform a calculation process for calculating the size information of the dust and calculating and outputting the concentration of the fine dust by applying the above-described fine dust measurement formula (FIG. 5 (a)).

As described above, when a moving object is used by error correction of fine dust measurement, it is possible to accurately measure the concentration of fine dust.

6 is a flowchart illustrating a process of an environment integrated monitoring method according to another embodiment of the present invention.

The integrated environmental monitoring method includes a database unit 10 for storing long-term environmental information and map information, a climate prediction unit 20, a priority monitoring area selection unit 30, a monitoring cycle determination unit 40, and an environmental information measurement unit ( 50).

Referring to the environmental integration monitoring method described above with reference to Figure 6,

First, the climate prediction unit 20 performs a climate prediction step for each unit monitoring area (S10) for generating climate prediction information for each of the unit monitoring areas where the environment-integrated monitoring target area is divided into a predetermined area.

Next, the priority monitoring area selection unit 30 compares the climate prediction information for each unit monitoring area with the environmental information of the entire environment-monitored area stored in the database unit, and the unit monitoring area where the ratio of the difference is greater than or equal to a certain value Priority monitoring area selection step (S20) of selecting them as priority monitoring areas is performed.

Priority monitoring area selection in the above-mentioned priority monitoring area selection step (S20) is the average value of actual observed long-term environmental information for the entire environment-integrated monitoring object, and the average value of climate prediction of each unit monitoring area predicted by the climate prediction model It is performed using the similarity of.

Specifically, after calculating the ratio of the corresponding climate average values predicted in each unit monitoring region to the average value of any one of the long-term environmental information stored in the database for the environment-integrated monitoring target region, the ratio is equal to or less than a certain ratio. It is configured to select unit monitoring areas as priority monitoring areas and to give priority to them in low order.

At this time, the equation for determining the similarity may be defined as the following [Equation 1].

[Equation 1]

Here, B (x _station, y _station, t ⁱ⁾ each of the environmental information measured by t _i time intervals over a long period in a fixed location in the environment the monitored area station fine dust, temperature, humidity, precipitation, wind direction, etc. An average value, B (x, y, t _i ) is a forecast for each climate, including one or more of the predicted temperature, humidity, rainfall, or wind direction for each ti time interval for each day in a unit monitoring area with x and y coordinates. It is information. The nt is the number of days included in the long-term long-term environmental information measurement period.

Here, F (x, y) is a function representing the similarity between the average value of the observed environmental information in the environment monitoring target area and the average value of the climate prediction value of the unit monitoring area included in the environment monitoring target area. That is, the difference between the environmental information B (x _station , y _station , t ⁱ ) measured at the _station and the predicted environmental information B (x, y, t ⁱ ) at each unit monitoring area is the environmental information B measured at the station. When divided by (x _station , y _station , t _i ), if the value is less than a preset value, the difference between the observed environment information and the predicted environment information is not large, so the observed value of the environment information is a valid environment in the unit monitoring area. It becomes information and thereby A has a value of 1. On the other hand, the difference between the environmental information B (x _station , y _station , t _i ) measured at the _station and the predicted environmental information B (x, y, t ⁱ ) at each unit monitoring area is the environmental information measured at the station. When divided by B (x _station , y _station , t _i ), if it is larger than the preset value (threshold), the difference between the observed environmental information and the predicted environmental information is large, so the observed value of the environmental information is It becomes invalid environment information, and thus A has a value of 0.

The value averaged over the entire period of environment information stored in the database unit 10 becomes the value of the similarity F (x, y) at the x, y position.

7 is a graph showing the similarity between air temperature as environmental information measured at an observatory for selecting a monitoring area and air temperature as predicted environmental information of unit monitoring areas.

In FIG. 7, the entire square represents an environment integrated monitoring area, and the area divided into an internal grid shape represents unit monitoring areas included in the environment integrated monitoring area. Then, the value at the ground station location (S) is set to 1, and the similarity value of each unit monitoring area is entered. Thereafter, areas where the similarity is less than or equal to a predetermined value are extracted, and priority monitoring areas are set by giving priority in order of low similarity.

In the case of FIG. 7, the monitoring areas were first set by using the similarity to the temperature among the environmental information, but after considering the correlation of the environmental information, the similarity graph for the rainfall is additionally created, and then the similarity of the temperature and the rainfall is combined. You can also set the monitoring areas first using the graph.

First of all, monitoring areas are areas where observations from fixed stations cannot be applied, and are areas that need direct environmental information observation for the area, that is, areas without environmental information monitoring.

As described above, after the first monitoring area is set, it is possible to identify the area where environmental information monitoring is absent on the map by displaying the corresponding area on the map of the environment integrated monitoring area.

As an example of this, FIG. 8 is a view showing an area without temperature monitoring, and FIG. 9 is a view showing an area without precipitation monitoring. 8 and 9, r denotes a monitoring area first, and S1 denotes a location for measuring environmental information using an integrated environmental monitoring module.

In addition, through the similarity determination graph, it is possible to display on the map a map in which a region in which the similarity is less than a certain percentage occupies a certain percentage in the area to be integrated environmental monitoring.
