摘　　要：针对辐射监测必须人员亲临现场的问题,为实现辐射远程监测,提出一种基于窄带物联网技术(NB-IoT)的辐射监测系统。该系统以STM32为主控制器,Boost前级升压结合电荷泵后级倍压为高压驱动,WH-NB73为数据传输模块,配合云端服务器和客户端完成辐射数据远程可视化显示。镅-241(Am-241)辐射实验和数据传输实验结果表明:系统可以从定性出发,定量监测环境中的辐射情况,数据传输稳定性达99.70%以上。该系统具有小巧便携、稳定低耗等优点,对辐射监测实现智能化管理有极高的应用价值。Aiming at the problem of radiation monitoring personnel must be present at the scene,a real-time radiation monitoring system based on narrowband Internet of Things(NB-IoT)was proposed to realize radiation remote monitoring.The system used STM32 as the main controller,pre-stage Boost combined with charge pump post-stage doubler as high-voltage drive,WH-NB73 was as the data transmission module,and cooperate with the cloud server and client to complete the remote visual display of radiation data.Americium-241(Am-241)radiation experiments and data transmission experiments show that the system can quantitatively monitor radiation in the environment with a data transmission stability of over 99.70%with the system starting qualitatively.The system has the advantages of compact and portable,stable and low consumption,and has high application value for intelligent management of radiation monitoring.
