摘要
目前的放射性物质监测技术和设备较为单一,无法满足各行各业的不同需求。为了对放射性物质进行实时监测,设计了一款可以对车辆、行人、包裹等为监测对象的通道式放射性监测仪。监测仪主要由NaI闪烁体探测器、ARM嵌入式系统构成,整机利用AD完成PCB电路板设计、AutoCAD完成整机外壳的设计和用Keil 5软件进行程序编写;利用人机交互软件和蓝牙模块实现远程在线监测,并对监测对象进行实时监测。最后对制备好的监测仪进行实时性能检测,发现其中微量放射性物质,同时发送报警信息,并完成对检测数据的储存。该系统应用对于现代化安检、反恐、维稳、治安防控和管理等工作将会发挥重要的作用,可有效预防灾害事故的发生,对于维护国家安全、社会稳定,保护民众的生命财产安全,具有积极和深远的社会意义。
The current technology and equipment for monitoring radioactive substances are relatively homogeneous and cannot meet the different needs of various industries.In order to carry out real-time monitoring of radioactive substances,a channel-type radioactivity monitor that can monitor vehicles,pedestrians,parcels and other objects is designed.The monitor is mainly composed of NaI scintillator detector,ARM embedded system,the whole machine using AD to complete the PCB circuit board design,AutoCAD to complete the design of the machine shell and Keil 5 software for programming;the use of human-computer interaction software and bluetooth module to achieve remote on-line monitoring,and real-time monitoring of the monitoring object.Finally,real-time performance testing is conducted on the prepared monitor,and trace amounts of radioactive substances are found.At the same time,an alarm message is sent and the storage of the detection data is completed.The application of this system will play an important role in modern security check,anti-terrorism,stability maintenance,security control and management,which can effectively prevent the occurrence of disasters and accidents,and has a positive and far-reaching social significance for the maintenance of national security,social stability,and the protection of life and property.
