Description

A field-type small unmanned radiation (capability) real-time continuous detection system to respond to radioactive accidents}

The present invention relates to a field-type small unmanned radiation (activity) real-time continuous detection system for responding to a radioactive accident, and more particularly, in case of an accident at a nuclear power plant such as a nuclear power plant, it is mounted on a vehicle or an unmanned aerial vehicle (drone) in a dangerous area Radiation (activity) data for the hazardous area is remotely transferred to a safe location outside the hazardous area by using a radiation (activity) detection device for drop-and-place deployment that transmits radiation (activity) detection information for the deployed risk area. It relates to a field-type small unmanned radiation (activity) real-time continuous detection system for response to radiation accidents that can be acquired and monitored.

In general, a conventional disaster prevention system in response to a radioactive disaster due to an accident in a nuclear facility sets an area suspected of radioactive contamination as a radioactive contamination risk area, evacuates residents in the radioactive contamination risk area, and simultaneously enters and exits the area. control, dispatch a disaster prevention personnel team to the radioactive contamination risk area to detect radioactive contamination within the area, and if radioactive contamination is found during the detection of radioactive contamination, the contamination location information is transmitted to the radioactive disaster prevention command and control headquarters, and these information The Radioactive Disaster Prevention Command and Control Headquarters, which has received the radiation, accumulates and organizes the received contamination location information, establishes a disaster prevention plan, and directs disaster prevention personnel to respond to the situation. That is, the disaster prevention personnel of the conventional disaster prevention team dispatched to the radioactive contamination risk area each carry a portable radiation (activity) detector and communicator, and each detection worker manually uses the portable radiation (activity) detector he or she carries. Detect radioactive contamination in the assigned area, and if radioactive contamination is detected through a portable radiation (activity) detector, report the location information to the radioactive disaster prevention command and control headquarters using a communicator, and the radioactive disaster prevention command and control headquarters It is a method of commanding and controlling responses to radioactive contamination risk areas based on situation information on the assigned area received from each team member.

Such a conventional disaster prevention system for radioactive disasters is unable to respond quickly and accurately to the accident expansion range, radioactive cloud movement path, and resident evacuation path.

In addition, recently, in the event of a nuclear power plant accident, a database of radioactivity diffusion pathways according to all weather conditions that can occur in the jurisdiction is established, and in the event of leakage of radioactivity due to a nuclear accident, the radioactivity diffusion pathway according to the weather conditions at the time of the accident is converted into a database. There is a radioactivity spread warning system for emergency response using a radioactivity spread database that selects from and responds quickly and accurately.

The contents of this conventional system are posted in Korean Patent Registration No. 10-1809669 (2017. 12. 11.).

However, the conventional disaster prevention method as described above relies on the intuition of a disaster prevention agent to manually detect radioactive contamination using a portable radiation (activity) detector. The reliability of the radiation (activity) is very low, and when radiation (activity) contamination is detected, the detection location information is reported through the communication device of the disaster prevention agent, and the radiation (activity) precision analysis and measurement team, which is put in later, detects the soil corresponding to the detection location information. Since the precise analysis and measurement of radiation (activity) is performed on the radiation (activity), practical and appropriate countermeasures for radioactively contaminated areas are delayed, and disaster prevention personnel may be exposed to radiation (activity) as disaster prevention personnel are put into the danger area and work is performed. There was a problem with that.

The present invention has been devised in consideration of the above conventional problems, and its purpose is to be mounted on a vehicle or unmanned aerial vehicle (drone) in a dangerous area requiring monitoring in the event of an accident at a nuclear power plant, etc. Acquire radiation (activity) detection information in the danger zone without deploying disaster prevention personnel in the danger zone It is to provide a field-type small unmanned radiation (activity) real-time continuous detection system for response to radiation accidents that can be monitored.

The object of the present invention is to detect radiation (activity) for drop-and-place deployment that is mounted on an unmanned aerial vehicle (drone) or vehicle and is dropped and deployed in a dangerous area in the event of an accident at a nuclear power facility to transmit deployment location information and radiation (activity) measurement values. device; A disaster prevention agent who transmits the received placement location information and radiation detection information at the same time as receiving placement location information and radiation measurement values from the radiation detection device for drop placement in a safe area out of the danger area a terminal; Radiation that stores the data received from the arrangement location information and radiation (activity) measurement values received from the disaster prevention personnel terminal, analyzes the overall accident situation based on the stored data, and transmits various items to the disaster prevention personnel terminal when necessary It consists of a disaster prevention command and control headquarters server; The radioactive disaster prevention command and control headquarters server stores the data received from the radiation (activity) detection device for drop arrangement according to a preset algorithm, analyzes the stored data, and classifies it into a radioactive contamination risk area and a radioactive contamination spreading area, It can be achieved by a field-type small unmanned radiation (activity) real-time continuous detection system for responding to a radiation accident, characterized in that the database is built as big data by generating the displayed map data.

The field-type small unmanned radiation (activity) real-time continuous detection system for responding to radiation accidents according to the present invention is mounted on a vehicle or unmanned aerial vehicle (drone) in a dangerous area requiring monitoring in the event of an accident at a nuclear power plant, etc. Radiation (activity) detection information within the danger zone without deploying disaster prevention personnel into the danger zone by using a radiation (activity) detection device for drop arrangement that is rapidly deployed within the area to detect radiation (activity) and transmits the detection information. By enabling disaster prevention personnel to safely conduct disaster prevention work without being exposed to radiation (activity), it is safer and more efficient by accurately detecting, acquiring, and monitoring radiation (activity) information about dangerous areas in real time.
