摘要
为了对分布于不同地域和环境中的放射源位置和环境剂量等信息进行实时监控,设计了一种放射源远程监控系统,完成了系统的总体方案设计和硬件、软件设计.系统将5G通信、北斗定位、嵌入式、光电探测技术和数据库技术相结合,实现了现场数据的采集、数据远程传输及实时监测;采用C/S架构设计了可视化远程监控平台,可以对放射源剂量和位置可视化显示并保存在数据库中,提出滑动平均和自适应Kalman滤波算法分别对剂量脉冲和位置信息进行处理.实际测试结果表明,系统具有实时采集、传输可靠等优点,能够对分布于不同地点的放射源剂量泄露和位置进行实时监控并预警.
In order to monitor the location and environmental dose of radioactive sources in different regions and environments in real time,a remote monitoring system of radioactive sources is designed,and the overall scheme design,hardware and software design of the system are completed.The system combines 5G communication,Beidou positioning,embedded technology,photoelectric detection technology and database technology to realize field data collection,data remote transmission and real time monitoring.The dose pulse and position information are processed by moving average filtering and adaptive Kalman filtering respectively to eliminate system error and sensor error.The visual remote monitoring platform designed by C/S architecture can visually display and store the dose and position of the radioactive source in the database.The actual test results show that the system has the advantages of real time acquisition and reliable transmission,and can monitor and warn the dose leakage and location of radioactive sources distributed in different locations in real time.
