Problems solved by technology

However, the existing security inspection equipment cannot fully identify special items such as explosives, and security personnel need to make preliminary judgments based on experience and open the package for inspection. This semi-manual method of discrimination is less likely to miss detection of hidden explosives. It is huge, and not only wastes a lot of manpower, but also increases the danger of security personnel

Abstract

The invention relates to a comprehensive explosive detection system and method based on an X-ray fluorescence (XRF) analysis technique. The system comprises a sealing box body for detecting, a conveying channel through which objects pass, a computer and a control system, wherein at least one group of energy spectrum detection assemblies are arranged above and below or on the two sides of the conveying channel and are used for detecting the varieties and content of elements in the movable or static objects in the conveying channel. According to the comprehensive explosive detection system and method provided by the invention, the principle of the XRF analysis technology is used for detecting explosives and the like and is applicable to the fields of online safety monitoring and the like.

Description

Technical field: [0001] The invention belongs to the application field of XRF analysis technology, and specifically relates to a new type of comprehensive detection system for explosives using X-ray fluorescence (XRF) analysis technology, and using this system to quickly detect explosives in moving or stationary large-volume objects. method of detection. Background technique: [0002] As one of the necessary methods for the analysis of material composition, X-ray fluorescence spectroscopy has been widely used in geology, metallurgy, building materials, petrochemical industry, semiconductor industry, medicine and health, environmental protection and other fields. A fast, accurate and economical multi-element analysis method widely used. [0003] Existing X-ray fluorescence spectrometers are usually designed with a sample stage, and the sample to be inspected is placed on the stage for detection. It can only detect small samples such as electronic components, soil, ore sample...
