基于GPRS的核辐射环境监测系统设计

为了长时间监测特殊区域内的核辐射情况,利用GPRS传输技术设计了核辐射环境监测系统,系统采用C/S架构设计由监测管理中心和多个监测节点组成;监测节点采用单片机MSP430F149作为控制核心,利用G-M计数管J403γ作为探测器,通过Time-To-Count方法实时监测周围环境中的辐射情况,并通过GPRS通信模块EM310建立与监测中心的TCP/IP网络连接将数据发送至监测管理中心;监测管理中心通过对接收来的数据进行处理、显示、分析,最终存入Access2003数据库备份;该系统适用于放射性科研院所、医院放射科和核电站周边等场所,以便尽早发现危险的存在,采取有效的措施,确保辐射场所的辐射安全,避免事故的发生。

Design of Nuclear Radiation Monitoring System Based on GPRS

In order to monitor nuclear radiation of special area for a long time,excessive exposure to radioactive rays will cause damage to the human body,and the nuclear radiation monitoring system composed of monitoring center and nodes is designed with GPRS transmission technology and C/S architecture.The monitoring node adopts MSP430F149 as control core and G-M counter J403γ as detector to monitor radiation in real time by Time-To-Count method,establishing TCP/IP network connection with monitoring management center through communication module EM310 and sending data to monitoring management center.The monitoring center processes,displays,analyzes received data,and finally backup to database Access2003.The system is fit for radioactive research institutes,hospital radiology and nuclear power plants to check out the dangerous as soon as possible,to ensure the radiation safety of work place and avoid accident.
