摘　　要：在进出关口,集装箱走私现象极为严重,对空箱的有效识别对于打击集装箱走私、维护国家经济安全和市场秩序具有至关重要的意义。目前,X射线探测和γ射线检测是集装箱非侵入式主要探测技术,但二者的使用均对人体造成一定危害,而且使用成本高、能耗大。鉴于此,为了节约更多检测成本,同时降低对人体的危害,设计了一种建立在强声激振的空箱智能检测系统,通过文献阅读法和实践探究法探讨分析了实现智能检测系统的关键技术,包括空箱检测技术、箱体适应技术等。研究显示,用强声发声器发出高声压级的声信号作用在箱体侧面,箱体另一侧用非接触式的微声传感器采集箱体的声振信号,通过声信号的方式可以有效判别集装箱是否为空箱。该研究成果可以为进出关口集装箱检测工作提供技术支持,维护国家安全。At the entry and exit checkpoints,container smuggling is extremely serious.Effective identification of empty containers is crucial for combating container smuggling,maintaining national economic security and market order.At present,X-ray detection and gamma ray detection are the main non-invasive detection technologies for containers,but their use poses certain hazards to the human body and has high usage costs and energy consumption.In view of this,in order to save more detection costs and reduce the harm to the human body,this article designs an intelligent detection system for empty boxes based on strong sound excitation.Through literature reading and practical exploration,the key technologies of intelligent detection system design are discussed and analyzed,including empty box detection technology,box adaptation technology,etc.Research has shown that using a strong sound generator to emit a high pressure level sound signal acts on the side of the container,and a non-contact micro sound sensor is used on the other side of the container to collect the sound vibration signal of the container.Through the sound signal,it is possible to effectively distinguish whether the container is empty.Hope this research can provide technical support for more container inspection work at entry and exit ports,and maintain national security.
