摘　　要：设计了以STM32单片机为核心控制模块的放射源实时监管与预警系统。该系统使用G-M计数器与GPS导航定位模块,通过物联网通信模块的GPRS技术将放射源的定位信息与剂量率信息发送至移动设备中的放射源监控软件,并可在放射源状态出现异常时及时预警,使监管人员立即采取应急措施,实现了对于放射源实时监管与预警。放射源实时监控设备性能测试显示其灵敏度为0.06 s^(-1)/(nGy/h),能量线性度为98.72%,稳定性为10.9%,重复性为4.05%。A real-time monitoring and warning system for radioactive sources is designed with an STM32 microcontroller as the core control module.The system uses a G-M counter and a GPS navigation and positioning module to send the positioning information and dose rate information of the radioactive sources to the radioactive source monitoring software in the mobile device through the GPRS technology of the IoT communication module,and can provide timely warning when the status of the radioactive sources is abnormal,so that the supervisors can take emergency measures immediately.The performance test of the real-time radioactive source monitoring device shows a sensitivity of 0.06 s^(-1)/(nGy/h),energy linearity of 98.72%,stability of 10.9%and repeatability of 4.05%.
