安检设备中多信息融合技术的数据重构

随着网络购物迅猛发展,人与人之间的物品交流越来越频繁。由于一些人自觉或不自觉地在包裹中参杂一些违禁品,如果发生漏检或错检,将对人民安全和国家安全造成威胁。本论文主要研究安检设备中X射线检测信息和电子鼻气(液)体检测信息对同一个检测对象的特征识别。设计电子鼻气(液)体检测系统,通过大量的实验,设定响应信号基础强度为80mv为预警值对危险性气液体报警。利用建立的信息融合系统对五种不同的包裹进行检测,对其有无危险品进行判断。

Data Reconstruction of Multi-information Fusion Technology of Security Check Equipment

With the rapid development of online shopping, the goods exchange among people becomes more frequent. Since some people consciously or unconsciously mixed some contraband in the package, if undetected or detected wrongly, it will pose a threat to people＇s security and national security. This thesis mainly studies the recognition of the feature of the same detection object by X-ray information and electronic nose gas （liquid） information in security check equipment. In the design of the electronic nose gas （liquid） detection system, through a large number of experiments, it sets the 80mv value of the basic strength of response signal as the warning alarm value for hazardous gas and liquids warning. This paper uses the information fusion system established for the detection of five different packages to judge the presence or absence of dangerous goods.
