CAN总线网络多节点区域辐射监测系统设计

Development of an Area Radioactivity Monitoring System with Mutli-Detectors Based on CAN Bus

研制了一套基于CAN总线网络的多节点区域辐射监测系统,系统主机集中管控多个就地处理箱,每个就地处理箱连接多个不同类型的探测装置,可在主机平台同时显示辐射场所内部各个监测点的实时辐射水平。不同类型探测装置(区域γ、区域中子、电离室、气溶胶等)采用统一的模块化软硬件设计,具备通用接口及通信协议,便于系统功能扩展和现场维护。

An area radioactivity Monitoring System with multi-detectors based on CAN bus was developed.The main control platform of the system,which can simultaneously display the real-time radiation level of each monitoring point inside the radiation site,centrally controls multiple LPDUs(local display processing unit),and each LPDU is connected with multiple different types of detectors,In this system,different types of detectors(including area gamma,area neutron,ionization chamber,aerosol,etc.)adopt unified modular design,with universal interface and communication protocol,which is convenient to expanse system function and maintain system on-site.
