Abstract

A radiation survey in motion and a control system in a radiation area are provided to prevent an unnecessary radiation exposition through location control and time control of a worker by automating radiation area and exposition management and worker management. A radiation survey in motion includes a radiation location data collector(110), a terminal controller(120), and a main controller(130). The radiation location data collector generates radiation exposition data and location data, and exchanges data by being connected to the terminal controller by a wireless LAN(Local Area Network). The terminal controller and the main controller are connected to each other by a CDMA(Code Division Multiple Access) or an Ethernet for communicating without limit of distance or space from a central control server.

본 발명은 원자력발전소를 포함한 병원, 학교, 연구소 등의 방사선관리구역 내를 편리하게 방사선을 측정하고 효과적으로 관리하는 시스템에 관한 것이다.The present invention relates to a system for conveniently measuring radiation and effectively managing radiation in a radiation management area such as a hospital, school, or research center including a nuclear power plant.

일반적으로 종래의 방사선관리구역에 대한 방사선 측정관리 기술은 몇몇 대 학 및 연구기관에서 다양한 방식으로 연구되어 일부 방식의 제품은 상용화되어 시판되고 있지만 아직도 대부분은 고가의 외국장비를 있는 그대로 도입하거나, 방사능 노출데이터의 정확한 관리 및 실시간 데이터 분석이 이루어지지 않고 있는 실정이다. In general, the radiation measurement management technology for the conventional radiation management area has been studied in various ways by some universities and research institutes, and some types of products are commercially available and commercially available. Accurate management of exposure data and real-time data analysis are not performed.

또한 종래 방사선측정기의 노출 데이터 측정은 데이터의 전송 및 중앙 통제실과 실시간 상호 데이터 교류가 이루어지고 있지 않아서 실시간 통제, 기록, 데이터 관리가 매우 불편하다. 즉, 원자력발전소 등의 고준위 방사선구역에서는 작업자가 전자식 개인피폭선량계를 착용하여 피폭 상황을 본인이 즉각적으로 확인할 수 있지만 중앙통제실과의 상호 데이터 교류가 실시간으로 되지 않으므로 작업자의 부주의 또는 불필요한 이동경로로 인한 과피폭이나 작업시간 지연 등의 통제를 효과적으로 할 수 없기 때문에 작업자의 방사선안전관리를 위한 적절한 통제 시스템이 절실히 요구되고 있다. In addition, exposure data measurement of the conventional radiometer is not very convenient for real-time control, recording, and data management because data transmission and real-time data exchange are not performed with the central control room. In other words, in a high-level radiation zone such as a nuclear power plant, the operator can immediately check the exposure situation by wearing an electronic personal exposure dosimeter. Due to the inability to effectively control overexposure and delays in working hours, an appropriate control system for the radiation safety management of workers is urgently needed.

따라서 이러한 불편함과 단점을 극복하기 위해서 원자력발전소 건물이나 병원, 학교, 연구소 등의 방사선관리구역에서 이동 간 방사선 측정관리시스템 도출이 필요하게 되었고, 본 발명으로 작업자의 이동경로에 대한 개인피폭량의 정확한 측정으로 과피폭 등의 사고발생시 피폭위치 확인이 용이하고, 실시간 피폭량 관리, 측정, 제어가 동시에 가능하게 되어 방사선안전관리의 효율성과 신뢰성을 크게 향상시킬 수 있다.Therefore, in order to overcome these inconveniences and shortcomings, it is necessary to derive the radiation measurement management system between movements in the radiation management zones of nuclear power plant buildings, hospitals, schools, and research institutes. It is easy to check the location of exposure in case of an accident such as overexposure by measurement, and it is possible to simultaneously manage, measure and control the exposure amount, which can greatly improve the efficiency and reliability of radiation safety management.

본 발명은 상기와 같은 문제점을 해소하기 위해 방사선관리구역의 공간방사선량 또는 표면 방사능오염도 측정을 휴대장치 및 관제 서버에서 상호 신호전달에 의해 양방향 자료 측정하여 실시간으로 방사선정보를 그려내며, 중앙관제 서버와 무선 및 유선으로 통신하여 실시간 데이터 관리 및 작업자관리를 할 수 있어서 방사선 측정관리의 효율성 및 편리성을 높이는데 그 목적이 있다.The present invention draws the radiation information in real time by measuring the bidirectional data by the mutual signal transmission from the portable device and the control server to measure the spatial radiation dose or surface radiation contamination in the radiation management area to solve the above problems, the central control server Its purpose is to improve the efficiency and convenience of radiation measurement management because it can communicate with and wirelessly and wired for real-time data management and worker management.
