Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chemical-

More particularly, the present invention relates to a system and method for responding to a chemical spill, and more particularly, to a system and method for preventing a chemical spill, The spreading range and the diffusion concentration of the leaking chemical substance corresponding to the leaked chemical substance information and the information about the flat-topographical information at the time of leakage in the flat-topography diffusion database containing the diffusion concentration are firstly provided in real time, The diffusion range and the diffusion concentration of the leaking chemical substance over time are predicted and provided secondarily using the base-station information reflecting the topographical information of the leaking position and the leaking chemical substance information, The present invention relates to a technique for providing a diffusion range and a diffusion concentration over time of a leaked chemical substance .

Recently, due to the diversification and quantitative increase of the use of chemical substances, risks to human life and environment due to chemical spill accidents have been widely spread not only in production sites but also in various industrial processes such as transportation, application, consumption and disposal of chemical substances .

Among them, the risk of acute poisoning, fire and explosion due to massive leakage of chemical substances causes damage to many persons and property at that time. Therefore, if there is not a proper response system, It can lead to such a big accident.

Considering that the risk of chemical spill accidents increases proportionally with the scale of the chemical industry, the risk of chemical spill accidents is rising as the production of chemical substances has recently increased sharply.

In order to minimize such risks, it is necessary to establish a national institutional system and build a professional response system.

In order for this response system to operate effectively, it is essential to provide quick response support information to the initial response personnel in the chemical leakage accident. To do this, the weather and the wind speed of the area where the chemical spill occurred is diagnosed by driving the weather diagnosis model, A method of predicting the diffusion of chemical substances by applying the diagnosed wind direction, wind velocity and chemical information to an atmospheric diffusion module driven by an atmospheric diffusion model has been proposed.

However, this method takes a considerable time to operate the atmospheric diffusion model, which is followed by the operation of the meteorological diagnostic model. As a result, it can not respond immediately to the actual chemical leakage accident. There is a problem that it can not be prevented.

Therefore, there is a need for a system for real-time prediction of the spread of chemical substances in the event of a chemical spill, in order to prevent personal injury, environmental damage, and property damage caused by a chemical spill.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing a configuration of a chemical substance leakage accident response system according to an embodiment of the present invention; FIG.

1, a chemical spill incident response system 100 according to an embodiment of the present invention includes a flat terrain spreading database 10, a leak spread confirmation unit 20, a leak diffusion prediction unit 30, And a data database 40.

The flat terrain spreading database 10 includes a flat terrain spreading database 10 for storing a flat terrain spreadsheet information in which the topographical information of a specific area is not reflected for each of a plurality of chemical substances and a flat terrain spreading range and a flat topography Diffusion Concentration. At this time, the range of the specific area may be changed depending on the setting of the user. For example, a specific area may be limited to the territory of the Republic of Korea or it may be the entire world.

The flat land spread range and the flat terrain spread concentration for each chemical included in the flat terrain spread database 10 can be constructed by the database building unit not shown in FIG.

The process of building the flat terrain database will be described below.

The database construction unit predicts the diffusion range and the diffusion concentration of the chemical substance with the passage of time using the chemical substance information and the planar terrain type listing information for each of a plurality of chemical substances in the specific area, ).

The database construction department can use the Lagrangian particle dispersion model to predict the diffusion range and concentration over time of the leaking chemical substance, taking into account the uncertainty of the turbulence.

The Lagrangian particle diffusion model emits virtual particles at a constant rate at the point of chemical leaks and gives the mass of leaking chemicals to the individual particles in consideration of the actual amount of released chemical substances and the rate of particle emission And operates to track the location of the spilled chemical particles along the turbulent wind field.

At this time, the terrestrial geophysical information on which the geographical information of the specific area is not yet collected may include geographical information of a specific area, for example, weather information and weather information which do not take altitude into consideration. The wind direction information may be a direction belonging to any one of n (n > 0) intervals divided by n azimuth at 360 degrees azimuth.

The wind speed information may be any one of m (m > 0) wind speed values having mutually different values belonging to the wind speed k (k> 0) [m / s] set at the wind speed 0 [m / s] Each of the m number of wind speed values may be an applied wind speed applied to each of m number of wind speed sections obtained by dividing the wind speed 0 to k [m / s] into the same or different sizes. This will be described with reference to FIG.

Referring to FIG. 2, the wind speed information may be any one of 18 wind speed values having different values belonging to an air speed 10 [m / s] set at an air speed 0 [m / s] May be an applied wind speed applied to each of the 18 wind speed sections obtained by dividing the wind power into the same or different sizes. For example, it can be confirmed that the applied wind speed of 0 ~ 0.25 [m / s] wind speed section is 0 [m / s]. The reason why the applied wind speed is 10 [m / s] in the wind speed section of 10 [m / s] or more as the set wind speed is 10 [m / s] Because it is the speed of the wind that moves the leaked chemical to another location in a time shorter than the time required to make it. This 10 [m / s] corresponds to the wind speed at which the leaked chemical is moved to another location within a time shorter than the time required to contaminate the leaked location of the leaked chemical at a rate that is comparable to the wind speed of the hurricane. In order to take into account the wind speed that can be influenced by the leaking chemicals, the wind velocity is divided by the wind velocity below the wind velocity of the typhoon, and the applied wind velocity is applied to each wind velocity section.

The type of the wind direction information may be 36 when the 360 degree azimuth angle is 36 directions.

Accordingly, the flat terrain spreading database 10 includes a flat terrain spreading range and a flat terrain spreading concentration of the corresponding chemical substance according to n x m predicted time lapse for each of a plurality of chemical substances. In the embodiment, when the number of chemical substances is 570, n is 36, and m is 18, the number of the flat topographic diffusion ranges and the flat topographic diffusion concentration information per chemical included in the flat topographic diffusion database 10 May be 369,360 (= 570 x 36 x 18).

The leak diffusion confirmation unit 20 identifies the leaked chemical substance information in the flat topography diffusion database 10 when the chemical substance is leaked to the specific region, And the real-time output is confirmed by checking the flat terrain spreading range and the flat terrain spreading concentration over time.

In this way, a flat landform in which the topographical information of the area where the chemical leaks is not reflected when the chemical leaks in the specific area, and the spreading range and spread of the flat terrain spread over time according to the chemical substance predicted in advance by the chemical information The concentration can be confirmed in the flat terrain spreading database 10 and outputted promptly in real time (by broadcasting), so that evacuation response and situation measures can be quickly processed in an emergency chemical leaking accident occurrence situation .

The leak diffusion predicting unit 30 outputs the flat topographic diffusion range and the diffusion concentration of the leaking chemical substance over time and then supports the continuous leakage accident such as decontamination and situation control. Estimates and outputs a diffusion range and a diffusion concentration over time of the leaking chemical substance using the base-station information reflecting the topographical information of the leaking position and the leaking chemical substance information. This is done after the leak diffusion predicting unit 30 receives the output information of the diffusion range and the diffusion concentration over time of the leaked chemical substance from the leak diffusion confirmation unit 30.

As described above, in the chemical substance leakage accident response system according to the embodiment of the present invention, when a chemical substance is leaked, first, the flat land spread range and the flat land spread concentration according to the time lapse of the leaked chemical substance are transmitted first, The diffusion range and the diffusion concentration of the leaking chemical substance are predicted and transmitted by using the reflected base-station information and the leaked chemical information, and the diffusion range and diffusion concentration information of the leaking chemical substance are binarized and output .

At this time, the base-station information reflecting the terrain information includes weather information, altitude information, and land cover information, and may be stored in the model input data database 40.

Among these, the weather information may include the wind direction and the wind speed per vertical altitude of a specific area. The types of the weather information include meteorological information measured in real time at the meteorological station, and forecast weather information predicted by the forecasting model. The weather information may be provided and updated from the weather information server 50 in real time every predetermined period, for example every 2 hours or whenever there is a change. The weather information server 50 may be, for example, a weather station server in the case of Korea.

The altitude information may be provided from the terrain information server 60 shown in Fig. 1, and may include a numerical altitude of a specific area. The terrain information server 60 providing such a digital altitude information may be a terrestrial geographic information server in the case of Korea. Also, the digital elevation information may be a digital elevation model of 100-m intervals provided by the Geographical Information Service.

The types of land cover information are shown in the table of FIG. 3, and are classified into three categories: marine, aquatic, ice, evergreen conifer, conifer, broad-leaf, Evergreen broad-leaved forests, steppes, myrtle, desert, reflection, tundra, evergreen shrubs, deciduous shrubs, mixed forests, crops / farming, irrigated farming, wetlands, evergreen coniferous forests, evergreen climbing forests, coniferous forests, Grassland, closed shrubland, open shrubland, grassland, cropland, pasture, urban area, and the like.

The chemical information may include the kind, specific gravity, weight, and the like of the chemical substance, and may be stored in the model input data database 40. In another embodiment, the chemical information may be stored in the chemical information server 70, in which case the chemical spill incident response system 100 may be configured to communicate with the chemical information server 70 .

The flat terrain spreading database 10 and the model input data database 40 may include a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (Random Access Memory), SRAM (Static Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read-Only Memory), a magnetic memory, a magnetic disk, or an optical disk. Additionally, such a flat terrain spreading database 10 and model input data database 40 may be external to the chemical spill response system 100. In such a case, the flat terrain spreading database 10 and the model input data base 40 may be configured to be capable of communicating with the chemical spill response system 100.

The leak diffusion predicting unit 30 combines the diffusion range and the diffusion concentration of the chemical substance over time with the GIS data, processes the image, processes the image, and broadcasts it to a plurality of terminals (not shown), a smart phone, a PC, It can be cast.

The leak diffusion predicting unit 30 can estimate the diffusion range and concentration of the leaked chemical substance over time using the Lagrangian particle diffusion model in consideration of the turbulence uncertainty.

The image processed results are shown in FIGS. 4 and 5. FIG. FIG. 4 shows a two-dimensional diffusion region, and FIG. 5 shows a three-dimensional diffusion region.

Referring to FIG. 4, it can be seen that as the distance from the point of occurrence of the leakage accident increases, the concentration of chemical substance decreases. Red, green, and blue are in order. The red area indicates the highest chemical concentration and the blue area indicates the lowest chemical concentration.

Referring to FIG. 5, it can be seen that as the distance from the point of occurrence of the leakage accident increases, the concentration of chemical substance decreases. The highest concentration of chemical substance at the point of spill occurs, and the farther away from the point of occurrence, the lower the concentration of chemical substance.

The block diagram of the chemical spill incident response system according to the embodiment of the present invention shown in FIG. 1 is merely classified from a functional point of view and does not mean an actual implementation method or a hardware method. The one or more configuration modules shown in FIG. 1 may be integrated or subdivided into one or more configuration modules, which will be apparent to those skilled in the art to which the present invention pertains.

6 is a flowchart illustrating a method for responding to a chemical leak accident according to an embodiment of the present invention.

Referring to FIG. 6, it can be predicted that the flat land spreading range and the flat land spreading concentration of the corresponding chemical substance over time are predicted by the information of the flat landformed geographical information and the chemical substance information, Thereby constructing a flat terrain spreading database (S10). At this time, the range of the specific area may be changed depending on the setting of the user. For example, a specific area may be limited to the territory of the Republic of Korea or it may be the entire world.

Thereafter, when the chemical substance leaks to the specific area, the information on the leaked chemical substance in the flat-topographical diffusion database and the information on the flat-topographical information of the leaked location are compared with the flat terrain spreading range over time of the leaked chemical substance, The flat land diffusion concentration is confirmed and output in real time (S20).

In this way, a flat landform in which the topographical information of the area where the chemical leaks is not reflected when the chemical leaks in the specific area, and the spreading range and spread of the flat terrain spread over time according to the chemical substance predicted in advance by the chemical information The concentration is confirmed in the abovementioned flat terrain spreading database and outputted in real time so that the evacuation response and situation measures in the emergency chemical substance leakage accident occurrence situation can be promptly processed.

The first step is to output the flat terrain spreading range and the diffusion concentration of the leaking chemical over time, and then, in order to support the continuous leakage accident such as decontamination and situation control, The diffusion range and the diffusion concentration of the leaking chemical over time are predicted and output using the base-line information and the leaking chemical information (S30). At this time, the diffusion range and the diffusion concentration of the leaking chemical over time can be predicted using the Lagrangian particle diffusion model in consideration of the turbulence uncertainty.

As described above, in the method for responding to a chemical spill incident according to the embodiment of the present invention, when a chemical substance is leaked, the flat topographic diffusion range and the flat topographic diffusion concentration are first transmitted according to the passage of time of the leaked chemical substance, Information on the spread of chemical substances leaked by using information of the leaked chemical information, and the diffusion range and diffusion concentration over time of the chemical substance are predicted and transmitted, and the diffusion range and diffusion concentration information of the leaked chemical substance are duplicated And outputs it.
