摘　　要：提出一种基于STM32和CAN总线的γ放射性辐射监测系统设计方法。以STM32F103作为核心控制器,利用能谱转化函数G(E),将测得的能谱直接换算成剂量,并通过CAN总线组网技术实现多个监测节点与监测主机的数据通信,解决辐射信号的采集与调理、剂量率转化、CAN组网等问题。测试结果表明:该监测系统具有通信可靠、抗干扰能力强、准确度高等优点,可以实现γ核辐射引起污染伤害的快速评估。A kind of design for γ-ray radiation monitoring system based on the STM32 and CANBus was represented. The design took STM32F103 as a core controller,making use of the G(E)function to transfer the entire obtained weighted spectrum to the radiation dose directly,CAN Bus technology was used to implement data communication among several monitor nodes and the monitor host. The system solved the problems of the acquisition and regulation of radioactive signal, the conversion of does. The benefit of radiation monitoring system was to make it more stable for the anti-interference capability and advantageous to quickly evaluate the damage caused by the γ-ray radiation.
