摘　　要：基于激光诱导击穿光谱(Laser-Induced Breakdown Spectroscopy,LIBS)技术、辐射探测(Geiger-Muller,GM)技术,结合口岸进口再生金属原料的应用场景和检测需求,开发出适用于海关再生金属原料现场快速查验的智能化设备,同时具有放射性污染和元素分析检测两种功能。该设备设计采用了激光聚焦技术,保证了LIBS在测试过程中等离子体的可靠激发与测量的一致性;采用微机电技术(Microelectro Mechanical Systems,MEMS)将放射性污染和元素分析两种检测技术进行改进、集成,并嵌入标准数据库与神经网络算法模型。该设备的研制实现了海关在口岸执法现场对进口铜、铁、铝3种再生原料的辐射和化学成分的快速检测;同时,通过4G/5G、Wi Fi、GPS对接海关执法系统,能够实现现场设备、海关系统数据实时互通,实现设备指令接收、检测数据的上传等,在现场即可完成布控指令的检验任务,提高了检验效率,助力智慧海关建设。Based on Laser-Induced Breakdown Spectroscopy(LIBS)technology and Geiger-Muller(GM)radiation detection technology,combined with the application scenarios and detection requirements of imported recycling metals at ports,an intelligent equipment suitable for on-site customs'rapid inspection of recycling metal has been developed.The equipment integrates the functions of radiation contamination detection and elemental analysis.The design of this equipment adopts laser focusing technology to ensure the reliable excitation of plasma and consistency of measurement during LIBS test.Microelectro Mechanical Systems(MEMS)technology is used to improve and integrate the two detection techniques for radiation contamination and elemental analysis and embeds standard databases and neural network algorithm models.The development of this equipment has enabled the customs to quickly detect the radiation and chemical composition of imported copper,iron,and aluminum recycling raw materials at port law enforcement sites.At the same time,by connecting with the customs law enforcement system through 4G/5G,WiFi and GPS,real-time communication between on-site equipment and customs system data can be achieved,and equipment instructions can be received and testing data can be uploaded.The inspection task of control instructions can be completed on site,thus improving inspection efficiency and assisting in the construction of Smart Customs.
