Description

  The present invention relates to a virtual accident-based radiation emergency on-site exploration training method, and more specifically, to design a virtual accident scenario similar to an actual radiation emergency accident, and according to the designed scenario, real-time on-site in real time The present invention relates to a virtual accident-based radiation emergency in-situ training method that can collect virtual location-based exploration data and train the central control center to reconstruct the distribution status of outflow radiation.

Due to the Fukushima nuclear accident in Japan last March 2011, the alert on the nuclear accident is rising. As a result, the Korean government has enacted the Nuclear Power Facility Protection and Radioactive Disaster Prevention Measures Act, and reorganized the radiation emergency plan area from the existing 8 to 10 km to 20 to 30 km.

Here, "radiation extreme (hereinafter simply referred to as emergency)" refers to an accident situation in which radioactivity (radioactive material) may leak out of various accidents or failures that may occur in nuclear facilities. It means that. In addition, “radiation emergency planning area” prepares for the occurrence of radioactive leak accidents at nuclear facilities, and concentrates in advance on resident protection measures such as preparation of protective chemicals and securing of relief centers, evacuation and evacuation, etc. Refers to the legal area set up to prepare. However, during radiation emergency, the radiation may not go beyond the radiation emergency planning area. Therefore, the "accident area" in the present invention means a place where an accident, a war, a terrorism, a natural disaster, intentional exposure to radiation, or a risk of being exposed to radiation is expected. That is, the accident area means not only the radiation emergency planning area but also all areas or areas that may be temporarily damaged by radiation.

When a radiation emergency occurs, information on the current status and trends of radiation emitted into the area, that is, radiation distribution information, should be the first priority for quick initial response and preparation and implementation of public protection measures. It is to grasp. This is because real-time radiation distribution information can determine the level and range of response to an accident.

At the time of emergency, in order to ensure radiation distribution information quickly in case of emergency, in order to secure radiation level distribution data in the accident area, monitoring utilizing multiple radiation monitors, a communication network, and a monitoring network with an operation server A system is provided.

A radiation monitoring system (RMS) is a device that measures radiation levels at land, sea, and air locations, usually installed at pre-post and post-procedure at locations in the accident area or moving around the accident area. Basically, it has a radiation level measurement function, a GPS function, and a real time communication function (these functions may be embodied in physically different devices). Stationary monitors are fixedly installed at major locations in areas where monitoring of radiation levels is required. As a mobile monitor, when radiation emergency occurs, it is moved and installed at a main point set in advance, it is mounted on a vehicle or ship, and it is moved on a road or sea in a preset path, a helicopter or There is a type that is mounted on an airplane and moved while flying, or a type that a person in charge directly carries and carries and moves to a predetermined or arbitrary route. In this way, the process of measuring the radiation level at the accident area site is called "exploration process", the movement route of various monitors is called "exploration route", and the radiation level information measured in the investigation process is called "exploration data". Do.

The operation server is an organization operating and managing the radiation emergency monitoring system (a national organization or an organization of a local government, a second organization involving various organizations, etc.), and may be defined by a legal regulation. , Hereinafter referred to as “management organization”.

According to such a monitoring system, in general, the radiation level at a specific position in the area is constantly measured by the fixed monitor and transmitted to the operation server. Then, during radiation emergency, while operating various mobile monitors along the search path, radiation levels will be measured in real time at several locations in the accident area and transmitted to the operation server via the network . The management organization of the operation server (the operation server may also be a plurality of physically separated devices) integrates position-based real-time radiation levels and derives radiation distribution information in the area, for example An organization such as the central command center of radiation emergency will decide the level and scope of the response to the accident based on this radiation distribution information.

The operation of the monitoring system to obtain such radiation distribution information is largely (1) exploration phase to measure the radiation level at the accident area site, (2) collecting real-time position-based radiation levels from each monitor, It is integrated into the situation grasping stage which derives radiation distribution information on a map, and (3) it is subdivided into the correspondence stage which decides the optimal accident spread prevention and the resident protection measures etc. based on the real time radiation distribution information. Ru.

On the other hand, as with the operation training of other basic emergency planning systems, in case of emergency, the monitoring system for acquiring radiation distribution information needs to perform virtual training regularly, periodically or aperiodically. . However, according to the conventional monitoring system, when virtual radiation emergency occurs, it is only possible to train how quickly the emergency plan monitor passes through the planned exploration route, and the radiation level of the virtual accident area There was no sense of tension or reality in the training because they were the same as normal. Furthermore, since the real-time position-based radiation level is a normal value in the exploration stage, the training for the situation grasping stage and the response stage in the latter half can only be separated without being linked with the exploration stage in the first half. That is, conventionally, the virtual training of the monitoring system has not been conducted organically, and the efficiency of the training has not been very high.

On the other hand, according to the prior art, the radiation exposure dose in a certain area is measured in real time by radio / radio, and the presence or absence of radioactive contamination due to an emergency accident is checked and managed, There is known a technology etc. which enables establishment of measures / measures such as protection measures for damaged areas of radioactive materials and residents in connection with GIS) (see Patent Documents 1, 2 and 3).

However, according to these, no systematic technique has been known as to how to make the training of various radiation contamination monitoring systems realistic and secure the effective operation of the monitoring system.

It will be obvious to those skilled in the art that various modifications and variations are possible within the scope of the technical idea of the present invention based on such an illustration.

As described above, according to the present invention, a plurality of radiation monitors for securing radiation level distribution data and radio communication with the monitors can be obtained so that radiation distribution information of the accident area can be grasped quickly in the radiation emergency. An on-site training method for virtual accident-based radiation emergency using a monitoring network having a server and a training server wirelessly communicating with the monitor, the scenario setting process, the virtual radiation level searching process, the virtual radiation distribution information The acquisition process is included. FIG. 1 is a conceptual relationship diagram showing the objects involved in the training method according to the present invention and the relationship between them, and FIG. 2 is the components involved in the training method according to the present invention and between them Is a diagram schematically illustrating the information transmission relationship of

The “radiation monitor” or “monitor” in the present invention basically has a radiation level measurement function, a GPS function, and a real-time communication function, and is installed in advance and after the accident in some places in the accident area. Or while moving along the planned route (exploration route) of the accident area, it is a device for measuring the position based real time radiation level on land, sea and air and transmitting it to the operation server. The "scheduled" means "defined in the action plan".

The “operation server” in the present invention is a server operated by a management organization that manages a radiation emergency monitoring system, which transmits position-based real-time radiation level data from a plurality of monitors, and integrates them into an area. Plays a role in deriving radiation distribution information of

The "training server" according to the present invention is a server linked to the monitoring network only in a training situation, and serves to set a radiation distribution information scenario and transmit it to a monitor.

In the present invention, at a particular point in time, each monitor measures or delivers only one radiation level information. Therefore, the radiation level information measured or transmitted by one monitor at a specific point in time is expressed as a single "datum", and the information in which these datums are collected is expressed as a plurality of "data".

In radiation accidents, colorless and odorless radiation can be widely distributed. In this case, it is not possible to measure the radiation level over the whole area in a wide area in real time even if installing as many monitors as practically possible. Therefore, the current situation is that there is no alternative but to measure the degree of contamination while moving the accident area with a fixed or fixed and mobile monitor. Reflecting such current conditions, "real time" in the present invention is not only substantially real time but may also mean time within a predetermined time range. In the latter case, for example, real-time data can also mean all radiation level data of the accident area, which has not passed 10 minutes from the measurement time.

In the present invention, the scenario setting process comprises: integrated real-time location-specific radiation level virtual data of the planned training area, wherein the training server has set virtual radiation levels according to planned training time zones of the planned training area from the training manager. It is a process of being input and saving. This is a process of inputting and storing [location-time-virtual radiation level] setting data consisting of virtual radiation level values for each time at a scheduled training time for each location in the training planned area.

At the time of setting of the scenario, the diffusion area distribution according to the contamination level of radioactive material, the accident radiation level according to the location of the training area-time zone (= setting datum), etc. will be configured.

It is preferable for visibility that the scenario is in the form of radiation level distribution information at a specific time displayed on the map of the training area. FIG. 3 illustrates an example where the scenario is displayed as contour line graphic on the map in this way. In the drawing, it is shown that the radiation level is higher when going from green to red, that is, the radiation contamination degree is higher. For example, the radiation level of green region is 100 nSv (nano sievert) / h or less, the radiation level of red region May be set to be 1 mSv / h or more. According to the illustration, radiation level information can be obtained for each position in the accident area at a specific time. The scenario may be determined by fixing a specific point in time, but it may also be determined by changing the radiation level distribution information over time, considering the transition of radiation emergency accident, the change of wind speed and wind direction, etc. Good. For example, more realistic training is possible by separately setting a scenario every 30 minutes from the training start time. However, since the basic training method is the same even if one scenario is used or a plurality of scenarios are set over time, the present invention will be described based on the setting of one scenario.

In the present invention, the virtual radiation level search process is a process of transmitting a virtual datum according to a scenario to each monitor, and one of two methods may be selected.

(1) The first method (pre-setting method) is that the training server transmits and sets the set scenario information to each monitor before the start of training. This setting is also possible offline. When such a method is selected, in the case of a mobile monitoring device, information on a radiation level on scenario information corresponding to a real time position (current position and time) while moving along an exploration route by an action plan (virtual Datum) is extracted. Also in the case of fixed or stationary, the same real-time virtual datum is extracted.

FIG. 4 shows an example of the scheduled search path of all the monitors. In the drawings, a route moving zigzag up and down indicates a search route of a monitor mounted on an aircraft.

(2) The second method (real time method) described below can be applied when the monitor does not have a function of storing and controlling the scenario information.

First, when training is started and the plurality of radiation monitors are mobile, the real-time position (the current position and time) is directly or the operation while moving along the exploration route according to a predetermined action plan. Transmit to the training server via a server. In the case of a fixed or stationary monitor, only one transmission of position information is sufficient because the position is fixed. Subsequently, the training server, which has transmitted the real-time position of each monitor, sets the scenario in the time on the respective monitor, that is, the scenario corresponding to the predetermined real-time position (namely, current position and time) set in the scenario. The virtual datum set on the scenario is transmitted to each monitor in the upper position.

After going through the virtual radiation level exploration process, it is preferable to have each monitor during training display a position-based virtual datum on a scenario in real time. At this time, a predetermined indicator (tag) may be coupled to the virtual datum in order to separate it from the actual measurement datum (= radiation level information actually measured). With the virtual datum displayed on the monitor, the site personnel train the appropriate site response plan.

In the present invention, the virtual radiation distribution information acquisition process is a process in which the operation server collects virtual datums from each monitor in real time and integrates them to obtain virtual radiation distribution information. The flow of this process is the same as the process of acquiring actual radiation distribution information, and is similarly divided into two stages.

First, each of the plurality of monitors transmits the real-time position-based radiation level virtual datum transmitted from the training server to the operation server. At this time, the virtual datum is a virtual datum extracted corresponding to the location where the monitor is currently located in the case of the “presetting method”, and in the case of the “real time method”, in real time from the training server It is a virtual datum transmitted. When the virtual datum is transmitted to the operation server, the actual measurement datum may be transmitted together, and a predetermined indicator (tag) may be coupled to the virtual datum to distinguish it from the actual measurement datum. Also, in order to emphasize the sense of reality, it is possible to correct (for example, add or subtract) the actual measurement datum to the virtual datum transmitted from the training server and transmit it to the operation server.

Subsequently, the operation server collectively stores real-time radiation data by position level virtual data transmitted from a plurality of monitors, and matches this with the search path and the virtual radiation level measured on the search path. Integrate in such a way. FIG. 5 visually shows virtual radiation levels measured on the search path on the search path as a result of training according to the scenario of FIG. 3 and the search path of FIG. In addition, the operation server analyzes such exploration results in an integrated manner and derives real-time accident area virtual radiation distribution information. At this time, the virtual radiation distribution information is preferably in the form of radiation level distribution information at a specific time displayed on the map of the training area. FIG. 6 shows an example in which the information obtained by FIG. 5 is analyzed and integrated, and virtual radiation distribution information is displayed as a contour line graphic on a map.

On the other hand, in emergency situations such as radiation extremes, the load on the wireless network is likely to occur. Therefore, in the present invention, each information (datum / data) is preferably transmitted at an appropriate predetermined cycle.

FIG. 2 schematically shows the enzyme elements involved in the on-the-spot exploration and training method based on virtual accident based radiation according to the present invention and the information transfer relationship between them, but the operation server and the training server are separated. While being, it is illustrated what is a form which communicates mutually. However, in the present invention, since the operation server and the training server are functional concepts, both may be physically installed on one server.

On the other hand, the present invention is not limited only to the virtual accident-based radiation-intensive field exploration training method, but also provides an evaluation method for evaluating the result of training by the training method.

That is, the following training evaluation process may be added after the scenario setting process, the virtual radiation level search process, and the virtual radiation distribution information acquisition process described above. In the training evaluation process, real-time position-specific radiation level virtual data on the scenario in the process (A) stored in the training server (that is, setting data for the “position-time-virtual radiation level” of the training area); The training server is to evaluate the training result by mutually comparing with the surveyed measured real-time position-based radiation level virtual data (that is, the survey data) in the process (C) integrated by the operation server.

For example, if training is performed based on the virtual radiation distribution scenario shown in FIG. 3, as a result, if the obtained result is the exploration radiation distribution information as shown in FIG. 5, how similar is FIG. 3 and FIG. 5 It is possible to evaluate whether the training has been elaborated or not by judging whether it is.

The operation process of the above training method will be explained again centering on related parties.

1) Before training, the training manager designs accident scenario information in which a virtual accident area for each accident time zone and a radiation contamination degree (radiation level) for each area are set at the virtual accident site and stored in the training server.

2) In the training course, when the emergency response monitor is activated, the monitor automatically communicates with the training server to transmit and set accident scenario information (settable offline).

3) Every time the monitor actually performs measurement, the virtual datum in the accident scenario is automatically calculated by the position information of the monitor (fixed installation position or collection of position information using GPS). At this time, the measurement datum and the virtual datum may be combined to be a virtual datum (= measurement value for training). The monitor may display all actually measured actual measurement datums and training virtual datums.

4) Position information, time information and virtual datum of each monitor are automatically transmitted to the operation server at the remote central command headquarters.

5) The site response person in charge at the accident site monitors the virtual datum of the monitor and trains the field response operation in an emergency.

6) The remote central command headquarters operation server integrates the virtual datum collected from the site and monitors it in real time, and trains the decision making of the resident protection measures through emergency response training and data analysis in case of emergency.

7) Train co-operation in response operations between the central command center and the site response personnel at the accident site through real-time sharing and will exchange of virtual accident information.

8) After the training, the training manager evaluates the training through comparison of accident response procedure, required time, accident scenario and training analysis results.

As described above, according to the virtual accident-based radiation in-situ training method according to the present invention, the hardware for effectively training the emergency response of the accident site and the control center in an environment similar to a real radiation emergency accident.・ Operate and evaluate radiation emergency response training at the accident site and central control center using the actual emergency response equipment and actual operation environment for the scenario of virtual radioactive material spill accident by the in-the-loop method It will be possible.

Also, when training on radiation extremes, various accident situation scenarios can improve the response to radiation extremes by conducting training to obtain radiation distribution information on expected accident areas in an environment that is actually similar.
