【摘要】：日本福岛核电事故再次为人类利用核能敲响了警钟,辐射应急监测是辐射应急信息的重要来源,是辐射应急的重要组成部分。车载辐射监测系统能够在辐射事故发生时快速赶到指定位置,对较大面积区域进行快速实时监测,向上级部门提供现场辐射环境状况,为事故调查、评价事故后果、采取防护行动、制定处置方案提供技术支持。本文在国内外有关核与辐射事故应急监测系统设计的基础上,结合广州市核与辐射监测要求,设计了一套基于GIS的车载γ辐射环境监测系统,该系统主要包括车载监测系统、数据采集发送系统、数据通信系统和数据管理系统。监测系统安装在应急监测车上,主要获取现场γ辐射剂量率、GPS定位信息,通过数据采集组件把数据打包并通过3G无线通信网络传输至监测中心处理。数据管理系统位于广州市环境监测中心站机房,主要是对监测数据的存储、数据分析和对事故应急的决策和指挥。基于GIS的车载Y辐射环境监测系统实现了现场数据的实时传输,实时显示车辆位置和环境γ辐射剂量率的变化,能够对大面积辐射环境进行监测,提高了辐射应急监测效率,满足了广州市辐射环境应急监测需求,提高了核与辐射应急监测能力。系统投入了2010年广州亚运会的辐射监测保障和多次应急演习,均很好的完成了任务。
[Abstract]:The Fukushima nuclear power accident in Japan once again sounded the alarm bell for mankind to use nuclear energy. Radiation emergency monitoring is an important source of radiation emergency information. It is an important part of the radiation emergency. The vehicle-borne radiation monitoring system can quickly get to the designated position at the time of the radiation accident, monitor the large area in real time, and provide the field radiation environment to the higher authorities. Provide technical support for accident investigation, evaluation of accident consequences, protective action and formulation of disposal plan. Based on the design of emergency monitoring system for nuclear and radiation accidents at home and abroad and in combination with the requirements of nuclear and radiation monitoring in Guangzhou, a vehicle 纬 radiation environment monitoring system based on GIS is designed in this paper. The system mainly includes vehicle monitoring system. Data acquisition and transmission system, data communication system and data management system. The monitoring system is installed in the emergency monitoring vehicle. The data is packaged by data acquisition components and transmitted to the monitoring center through 3G wireless communication network. The data management system is located in the computer room of Guangzhou Environmental Monitoring Center, which mainly stores the monitoring data. Data analysis and emergency decision making and command. The on-board Y radiation environment monitoring system based on GIS realizes the real-time transmission of field data, shows the change of vehicle position and environmental 纬 radiation dose rate in real time, can monitor the large area radiation environment, and improves the efficiency of radiation emergency monitoring. It meets the needs of radiation environment emergency monitoring in Guangzhou and improves the ability of nuclear and radiation emergency monitoring. The system has been put into the radiation monitoring guarantee and many emergency exercises of the 2010 Guangzhou Asian Games.
