Description

[0001] The present invention relates to a method for preventing the spread of risk in an industrial complex,

The present invention relates to a method for preventing the spread of risk in an industrial complex, and more particularly, in recent years, accidents such as leakage and explosion of dangerous substances in a national industrial complex frequently occur, In order to provide a countermeasure for this, a systematic survey analysis is conducted for the development of the risk diffusion prediction system in the industrial complex, and then the risk diffusion prediction system in the industrial complex is developed, To a method for preventing the spread of risk in an industrial complex that provides a method for preventing the spread of risk.

Since humans have utilized chemical substances, more than 15 million chemical substances have been commercially used worldwide, and about 43,000 chemical substances have been distributed in the country. Therefore, thorough control of chemical substances is absolutely necessary, and through this, we must provide many benefits for the use of chemical substances of modern humanity. However, damage caused by accidents caused by natural weather and human carelessness, such as chemical leaks and explosions, is continuously increasing. Moreover, as the nation's new growth engine industries and technologies such as semiconductors, displays, and solar power have developed, the use of toxic and chemical substances has been continuously increasing, and exposure to chemical leaks and explosions has increased In fact. These chemical-related accidents occur almost evenly in carelessness, aging facilities, and transportation accidents. Recently, accidents such as leakage of chemical substances and gas due to various aged facilities installed at industrial sites or equipment failures and explosion thereof have been increasing rapidly, .

While this incident would not be a problem if it remained in a mere accident, the reality is causing serious problems in various sectors. For example, if we look at the economic and industrial sectors first, the amount of primary damage caused by gas leakage in Gumi Foshan in 2012 was 17.7 billion won, including the secondary damage such as human health and environmental ecology It can be said that the economic loss is increasing more and more. In the social sector, psychological risks to residents living near industrial complexes or chemical complexes after the leakage and explosion of various hazardous chemicals have increased considerably. As a result, the psychological stability in the lives of the residents is significantly lowered.

As such, chemical accidents are one of the serious problems that can have a devastating effect on business management, management and society in general because of the large scale of human, physical, mental and economic damage in a short time. As such, chemical accidents are most likely to be prevented in advance because they lead to mental, social, and economic damages, as well as major accidents that cause air pollution and human accidents. Therefore, the government has been revising the Hazardous Chemical Substance Management Law to prevent chemical accidents in order to secure national life safety and safe management of enterprises. However, in reality, there is no scientific and systematic means for the cause of chemical accidents and early response . In addition, comprehensive management of dangerous facilities handling hazardous materials and vulnerable disaster facilities, and detailed data on these facilities are not systematically managed, so it is necessary to identify a large number of personnel It is time-consuming, and there are many difficulties in eliminating these risk factors, or developing activities to prevent them from spreading and minimizing damage.

Therefore, although various studies have been made to solve such conventional problems, the problem is still not satisfactorily solved. For example, Korean Patent Registration No. 10-1627981 (Patent Document 1) , Which is an unspecified number of residents and living organisms due to the widening of the damage range and cumulative prolongation due to the spread of various human resources accidents such as hazardous chemical gas diffusion, crude oil leakage, plant explosion, Based on the Big Data, we continually check for human accidents, which have a profound impact on the environment, before the occurrence of accidents, to systematically establish the management of hazardous chemicals accompanied by high diffusion and high risk, You should be able to quickly respond to and respond to local residents. In addition to minimizing the risk of accidents, it is necessary for local people to recognize the area where the disaster occurred and to avoid the area where the disaster is spreading and to move to the safe area by the shortest route. Discloses a disaster response method based on object intelligence communication that minimizes human injury after a disaster has occurred. Korean Patent Laid-Open Publication No. 2016-0121706 (Patent Document 2) discloses a facility safety management system and method , A safety sensing device for safety management of industrial facilities based on inter-machine communication and object Internet, and a facility for monitoring the dangerous situation of industrial facilities through communication with safety sensing device based on big data base and geographical information A management server, and a manager of the facility safety management server The subscriber unit and the stay, discloses a facility safety management system and method which is characterized in that it comprises a data logger to organize the data collected and transmitted between the safety sensors and facility safety management server provides. However, the invention disclosed in the above-mentioned patent documents has a problem in that it is far from being a method for predicting the risk diffusion of a chemical-related accident.

Therefore, the inventors of the present invention have found that, in industrial sites having chemical facilities, especially where large facilities such as national industrial complexes are located, the management system for the information on chemical substances distributed and the places where the chemical substances are handled is insufficient In addition, in the case of a disaster accident within the national industrial complex, it is recognized that there are not enough predictive technologies to take into consideration both direct damage and secondary damage that spread to neighboring areas. From this, The present invention has been completed.

The risk prediction system for industrial complexes according to the preferred embodiment of the present invention and the method for preventing risk diffusion using the system according to the preferred embodiment of the present invention perform a systematic investigation analysis for the development of a risk diffusion prediction system in an industrial complex, Developing phases, and analyzing the hazardous area based on the risk diffusion information and providing a method to prevent the spread of the risk from this. According to a preferred embodiment of the present invention, the risk prediction system for industrial complexes and the risk diffusion prevention method using the same according to the present invention is directed to the risk diffusion in industrial complexes, in particular, the risk of toxic chemicals in industrial complexes. The harmful chemical substances according to the present invention are in accordance with the "Hazardous Chemical Substances Management Act", though not particularly limited thereto. According to this, harmful chemical substances are toxic substances, observed substances, restricted substances, prohibited substances, , And hazardous substances are defined as hazardous or potentially hazardous chemicals. In the "Industrial Safety and Health Law" or "Dangerous Goods Safety Management Act", chemical substances are classified according to the law. , 86 kinds of observation materials, and the like, all of which can be targeted.

16,547 chemical handling companies in Korea handle about 41,000 species, including 612 toxic substances, 64 observed substances, 12 restricted substances, 60 prohibited substances, and about 400 new chemical substances. And 432,541 thousand tons.

As the number of chemical substances is being handled, the frequency of accidents increases year by year. In particular, the annual average rate of chemical accident incidence in Korea has increased rapidly to 62%.

As shown in Figure 1, there are two national industrial complexes (Ulsan and Mt. Onsan) and 18 general industrial complexes (Maeok, Modul, Zhongsan, Gilchon, and Shin) A total of 24 industrial complexes have been designated as 4 sites (Dalcheon, Dudong, Doosoo, Sangbuk). In the case of the Ulsan Mipo National Industrial Complex, support facilities such as the factory site were launched with the groundbreaking ceremony in 1962, and it was selected as a petrochemical industrial complex through a regional expansion announcement in July 1967. It is divided into Ulsan Petrochemical Complex, Yeosu District, Maeam District, Yongyeon District, Hyomun District, and Mipo District in general, depending on the development process of the industrial complex, the process of accumulation of affiliated factories, and characteristics of the industry. In addition, Ulsan Petrochemical Complex includes SK Chemicals, SK Innovation, SK Chemicals, SK Chemicals, Samsung Petrochemical, and Hanwha Petrochemical, as well as large petrochemical companies and fine chemical companies (Songwon Industries, Samsung Fine Chemicals, etc.) It is the largest petrochemical complex in the world with 300 petrochemical companies including BASF, DuPont and Dow.

For example, in case of an accident, the type of emergency situation, the place of occurrence of emergency situation and the place of occurrence of the emergency situation, It shall be repeatedly broadcast three or more times, including the contents of the protection measures, and shall issue emergency warning broadcasts and announce announcements in case of concern about the spread of pollution in boundary alarms or serious alarms. If there is no urgent need for the protection of the residents, the workplace environment and safety team will request the local government to broadcast the protection measures for the residents. (If the local government delegates the broadcasting to the workplace, If emergency measures are required, emergency broadcasts shall be used to broadcast emergency measures to residents within at least one kilometer and notify local governments of the broadcast contents.

In the present invention, an analysis matrix of a sensor type and a harmful substance according to a disaster type according to a preferred embodiment of the present invention is analyzed. In this case, an analysis technique can be presented which has the following characteristics:

(1) Matrix analysis: By analyzing an object in the form of 2x2, 3x3 matrix (row, column), position the attribute on the x axis and the y axis, It gives meaning to the object.

* (2) Correlation analysis: The analysis technique used to analyze the relationship between variables is to examine how closely one variable changes with other variables.

(3) Frequency analysis: It is used to calculate the distribution of frequency distribution and the characteristics of distribution of variable values.

(4) Analysis of variance (ANOVA): Used to test differences between two or more groups.

(5) Regression: Used to analyze correlations between variables and to predict changes in other variables from changes in specific variables.

(6) Cluster analysis: This is a method of grouping people into homogeneous groups based on the similarity of various characteristics of objects.

Table 1 below compares the characteristics of the analysis technique with the input and output specifications.

A weighting matrix analysis technique, which is a variation of the matrix analysis technique, is widely used in selecting an optimal alternative among various alternatives of a specific process. The weighted matrix analysis technique, which is a variation of the matrix analysis technique, is used to select equipment and systems suitable for risk diffusion prediction and situation management technology in the event of a dangerous situation. Analyze individual factors of major areas and areas through information gathered through literature, questionnaires, interviews with working people based on their own scenarios, etc. Based on the analyzed information, we set individual factor weights for the area. Based on this, matrix analysis techniques can be used to select equipment and systems that are suitable for risk diffusion prediction and situation management technology in case of a risk situation.

A test bed can be selected through the above-described matrix analysis technique. For example, a questionnaire survey of 68 factories in the Ulsan National Industrial Complex revealed that the risk of accidents among hazardous chemicals was high among hydrochloric acid, hydrofluoric acid, and sulfuric acid. In fact, Sulfuric acid. Based on the results of the accident cases and questionnaires, the weight of the three substances is weighted, and the contact with the company that has the accident of FOSHAN, Sensor information, hazardous chemical information, etc., and analyzed the result of matrix analysis.

If the company is selected as the test bed company, the test bed information is received. This is to derive a scenario selection in case of an accident. Scenario selection should be the worst. Such scenario selection should include a breakdown number for the target facility and provide a basis for the evaluation criteria (eg, size of leaks, leaks and leaks, Puddle area and volume, etc.). The worst case scenarios were selected as follows: flammable material fire, explosion representative scenario, toxic substance leakage representative accident scenario, wind speed 1.5m / s, atmospheric temperature 25 degrees, atmospheric humidity 50%, atmospheric stability F (very stable) Leakage time: The maximum amount in the vessel or piping contains leakage for 10 minutes.

Then, we carry out impact evaluation in the area around workplace. Table 2 below shows an example of the influence of the surrounding area.

According to a preferred embodiment of the present invention, a system is configured using an aerial photographing result of a test bed company in the present invention. FIG. 4 shows an example of a test bed company aerial photograph.

According to a preferred embodiment of the present invention, the development of the industrial complex risk diffusion prediction of the present invention includes the development of sensors (atmospheric, meteorological), CCTV information-based monitoring technology, and evaluation of atmospheric diffusion optimal models considering the terrain and property.

The development of the sensor (air, weather) and CCTV information based monitoring technology includes the requirements collection and design process and the DB table design. The system construction consists of building corporate information, building chemical information, .

The requirements collection is gathered through a number of meetings with the National Institute for Disaster Reduction and the requirements are collected and reflected in the design content after confirmation. The basic design process is to receive AWS information and to accumulate in the DB, to develop the monitoring technology by confirming the wind field from the accumulated DB, (SK communication data, aggregate population density, and building information), which are basic DBs, are the structures that express the population information, human information, land cover information (SK communication data, aggregate population density, building information).

Based on the above architecture design, detailed menu is composed and UI / UX design and screen design are proceeded. In order to proceed with the menu design, detailed UIs for each function are grasped and a UI for confirming related information at a glance is constructed. Then, the main scenarios of the screen are configured through the menu design, and the design of each screen is proceeded. The detailed description and the structure of the functions to be specifically developed through the screen design shown in FIG. 6 are grasped and detailed UI design and screen design .

Next, based on the logical design of the database, the ERD is structured again and the detailed table specification is structured to complete the database basic structure.

The DB table design first defines the main table. The DB table constitutes the main table analyzed and designed so that chemical information, company information, and IOT (AWS) information can be integrated and managed.

The company information is composed of general information of company, storage facility information, disaster prevention information, and so on. The company information consists of general company information and emissions transfer company information.

The IoT (AWS) table design is based on information from the Korea Meteorological Administration and 20 new information from the Disaster Safety Research Institute. The AWS base point information and AWS standard point number log information are organized into tables, and the table structure is designed as shown in FIG.

The system construction according to the preferred embodiment of the present invention is constituted by enterprise information construction, chemical information construction, and real-time wind field construction.

The enterprise information according to the present invention can be selected based on the test bed company as a test bed and the enterprise information other than the test bed company can be selected based on the 2013 emission moving company. The company information is searched based on the search condition of the handling substance, city, county, and company name. Basically, the general lot number, new address, and name search are implemented through the API of the v world search engine. In addition, the emission movement company consists of menu of location information, general information and emission / movement information of companies in Ulsan area. It uses information disclosed in the PRTR information system managed by the National Institute of Environmental Research In order to provide information and presentation, the information of 193 companies in Ulsan area should be DB as of 2013.

The chemical information construction according to the present invention can be constructed based on the revised edition of the "Material to Key Information Guide to Accidents" 2014 provided by the Ministry of Environment and Chemical Safety Agency. It is suitable for the atmospheric diffusion model in the system investigation analysis for the development of the test bed and industrial complex risk diffusion prediction system of chemical substances, and it can be determined as hydrogen fluoride in the dangerous and fast air diffusion material. Such hydrogen fluoride is a substance which is made into a gaseous state when heating fluorspar, which is a main component of fluorinated calcium, together with concentrated sulfuric acid. An aqueous solution of hydrogen fluoride is also referred to as hydrofluoric acid or hydrofluoric acid. Unlike other hydrogenated hydrogens such as hydrochloric acid and hydrobromic acid, which are classified as strong acids, hydrogen fluoride is classified as weak acid because strong hydrogen bond acts between fluorine and hydrogen and ionization does not occur well. However, the higher the concentration of the aqueous solution, the stronger the acid and emits a stimulant odor. Especially in the gaseous state, it is lighter than air and easily diffused, and hydrofluoric acid solution and hydrofluoric acid gas are acute and contact poison, which is a weapon of chemical attack.

As described above, according to a preferred embodiment of the present invention, the present invention includes real-time wind field construction.

The law related to the wind field induces the district unit plan to include the protection, creation, connection, and circulation of water and air in the district unit plan in the 「National Land Planning and Utilization Act」. The wind field is directly connected to the circulation of the air, and the law requires the wind field to be taken into consideration when establishing the district unit plan. However, there is no mention of further specifics as to how and what to consider for the circulation of air.

The study on the wind field has been focused on the improvement of the urban ventilation function by reducing the heat island phenomenon by securing wind routes such as urban planning, air environment improvement and environmental impact evaluation in local governments such as Seoul, Anyang, Daegu, and Busan The purpose of this study is to introduce the urban planning system considering the urban climatic factors in order to establish a sustainable urban development strategy. In Tokyo, Shinagawa Osaki district in Tokyo, buildings and roads are arranged around the river to smoothly disperse winds blowing into the city center. In Fukuoka, Japan, we conduct a numerical simulation by combining the climate analysis map with the urban structure, and through the urban heat environment analysis through it, we propose guidelines and future images to improve the thermal environment for commercial and business areas in the center of Fukuoka. In Stuttgart, Germany, urban planning is introduced through urban climate analysis to establish urban green spaces to solve air pollution problems, and to establish wind farm plans such as limiting the construction and spacing of buildings.

One of the components of the present invention is the Internet, which is used for IoT-based detection and response services of industrial sites. It is designed to secure the safety of workers from electric shock, dropping, and collision of workers. This service is an industrial safety convergence service that can improve the productivity of the industrial site by responding to the crisis situation by detecting and forecasting the risk factor of the industrial site in real time, To reduce industrial accidents through management of industrial sites, to increase export of industrial technologies such as construction and plants, and to increase work productivity by working safely in a safe work place, thereby making it possible to increase net profit.

In the present invention, the Internet of the object is linked with the wind field to prevent danger prediction and diffusion. The data of the weather observation sensor include data of wind data, wind direction, wind speed, precipitation data, sky status data, It helps to forecast the spread of chemical leaks and to estimate the scale of damages by using sensor data of wind direction and wind speed among data of data logger device.

The development information for real - time wind field implementation to utilize the information of wind field consists of reverse distance weighting method, wind flow layer representation and real time wind tunneling as detailed below.

The above-described inverse distance weighting method is an interpolation method used in the field of terrestrial statistics. In this method, a closer weight is applied to a closer measured value, and a higher weight value is applied as the distance is shorter Weighted method. Conversely, the farther away from the measured value, the less the influence of the weighted value. The interpolation value of the interpolation point is calculated as follows.

In the above equation, the weight (W) is calculated in inverse proportion to the square of the distance as follows

If a real-time wind field is implemented by the above-described method, for example, it can be as shown in FIG. The information in FIG. 8 is screen information on 14 December 2016, which was tested at about 14:00 on December 13, 2016, in which real time wind fields are expressed using AWS weather information of satellites in the place where the weather station is installed. FIG. , And FIG. 8B is a wind field representation of a newly installed AWS standard.

8A shows that the space between AWSs is so wide that wind information is not detailed. In the real-time wind field, the direction of the wind according to the weight is identified through the IDW analysis of the information between the simple AWS and the wind. It can be seen that AWS is suitable for confirming wind direction and intensity in a large area. However, as shown in FIG. 8B, the wind field in the narrow region of FIG. 8B shows the wind direction of the ground surface by visually displaying the change amount of wind in 1 minute in real time by dense distance between AWSs, The visual representation of the wind in the long term provides a basis for analyzing the local wind.

FIG. 8C is a real-time wind field and wind rose diagram of Ulsan 152 of the Korea Meteorological Administration. As a result, not only the existing AWS but also the newly installed AWS information can be represented, thereby making it possible to view the wind direction in a wide area and narrow area as a whole. However, it is possible to check the median values according to the IDW analysis for the wind direction and the wind direction of the arbitrary area.

The wind rose diagram of the present invention described above is shown in a graph of a radiation pattern obtained by dividing the frequency of appearance of wind direction in each direction for each of the observation points at any observation point in eight directions to sixteen directions. Because it resembles, it is called wind rose. In general, the percentage (%) of the frequency of occurrence is represented by the line connecting the outer ends of the diagonal lines or the length of the diagonal line on the bearing plate corresponding to each direction of the wind. However, the frequency of appearance of the calm is displayed in the center or side of the separate graph. Wind roses also show the frequency of each wind direction class. Wind charts used today by meteorologists allow you to see the rate of wind blowing from each direction during the observation period, and sometimes show the intensity of the wind and the rate at which no wind or weak winds are observed. When constructing an airport runway, wind roses are needed through the year, considering that the wind direction changes depending on the season. Typically, the airport's runway location decision is based on weather data and design aircraft specifications for 5 to 10 years, and the wind direction is plotted to plot the wind direction and wind speed, and the direction of the runway is set to 95% or more. In other words, it means that the wind and wind in both directions of the runway (in the opposite direction of the runway) should be 95% or more. The wind direction and wind speed at the airport affect not only the direction of the runway, but also the way of control during takeoff and landing, side winds, blasts, and even aircraft load. In this way, it can be utilized for spreading the risk by analyzing the main wind direction of each branch utilizing the real - time weather information and the past weather information by utilizing the wind route.

In order to express such wind roses, wind direction and wind speed information are needed. The main flow chart for utilizing the weather information using the SK Planet API to receive the data is as shown in FIG.

Diffusion of hazardous chemicals can be predicted with reference to the wind field and the wind chart described above. In order to express the spread of hazardous chemical substances, the results obtained from the simulator for analyzing the hazardous substances are analyzed and the results are stored in a server and expressed on a V world map. Visual effects can be obtained by expressing analysis and analysis results using 3D spatial information in 3D spatial information. By predicting the consequences of the hazardous chemical diffusion, it can help to plan for proactive response.

The implementation of this prediction is to get the information of the nearest AWS based on the current center coordinates (latitude and longitude) of the V world. If the current weather reflectance is applied after moving to another location, it is possible to predict by applying the diffusion result of other weather conditions, even if the weather condition is not nearby. The user adjusts the wind direction and wind speed to predict the spreading result. The application method of hazardous chemical diffusion is made by selecting explanation -> time selection -> analysis. If the time selection is "- * hourly selection * -", the analysis results are automatically displayed up to 4 hours in 20 minutes. If you select the description when storing, the chemical (CAS number), the time selection (20 minutes, 1 hour, 2 hours, 3 hours, 4 hours), the chemical name (hydrogen fluoride) (Storage concentration of the selected storage facility chemical) information. 10 is a view showing the diffusion of hydrogen fluoride (hydrofluoric acid) at the time of one hour elapsed under the conditions of a wind direction wind wind and an air velocity of 2.10 m / s by receiving AWS weather information from Ulsan Jangsaengpo. Also, although not shown, the diffusion results can be checked by changing the direction of the wind direction under the same conditions. As a result, if the east wind is blown, it can be predicted that the spread of the pollutant spread to the northeast due to the influence of the south of the test bed enterprise .

The atmospheric diffusion optimum model considering the topography and the ground is evaluated by the atmospheric diffusion optimum model. The analysis of each software characteristic is performed by classification of the hazardous chemical substance diffusion analysis software (model), and the comparative analysis between the models is performed. It is to evaluate the atmospheric diffusion optimal model by comparing the basic input values and characteristics of the used software and to select the appropriate model. If software is not available, the model can be evaluated in a basic analogy format through literature and reference materials.

The above diffusion analysis software is a diffusion model that can simulate the PUFF of a pollutant source by considering the change of the wind field as an abnormal state model which can consider the PUFF movement. It is a CALPUFF model expressing concentration or deposition amount per hour in a specific region, ALOHA model, which simulates the spreading of rainfall spreads, and the atmospheric model RAMS (Regional Atmospheric Modeling), which combines the cloud model of Cotton to simulate atmospheric diffusion and the atmospheric circulation model of Pielke ' The RMP * Comp program, SLAB, a model for simulating the atmospheric diffusion of leaner than atmospheric leaks, and the German Meteorological Agency As a result of this study, There is KLAM21 (Kaltluftabflussmodell_21) which can analyze and predict the generation.
