Problems solved by technology

[0004] For metal contraband such as guns and knives hidden in clothing and books, due to their density is much higher than that of clothing and books, and they have obvious shapes, traditional X-ray imaging technology can show more gray particles. degrees of hierarchy and distinct outlines, making it easier to identify
For organic substances such as explosives or drugs, due to their low density and small attenuation of X-rays, more gray levels cannot be displayed; and explosives or drugs have no specific shape characteristics, so it is difficult to distinguish

Embodiment Construction

[0018] The structure and working principle of the present invention will now be further explained in conjunction with the accompanying drawings of the specification:

[0019] As attached figure 1 As shown in 2, 3, and 4, the present invention includes an X-ray source carrying case 1, a projection dark box carrying case 3, and a controller carrying case 4.

[0020] The X-ray source carrying case 1 includes an X-ray generator 23, a micromotor 26, and a ray filter plate 24 and a filter plate switching device are installed at the X-ray source ray outlet on the box body of the X-ray source carrying case 1 25. The micromotor 26 drives the filter plate switching device 25 to switch the ray filter plate 24, thereby obtaining X-rays of two different energies. The X-ray source can be either a ray source that works in a continuous mode or a ray source that works in a pulse mode. There is no strict requirement on the peak voltage of the ray source, so it can be flexibly selected according to...

Abstract

The portable double energy X-ray inspection device includes X-ray source carrying case, projecting camera obscura carrying case and controller carrying case. The filtering board inside the X-ray source carrying case is first controlled in the energy I position, the computer obtains the transmission image of the detected object and treats the transmission images in different greys by means of the FISCAN software package for the inspector to judge primarily. The filtering board is then set in the energy II position to obtain the new transmission image of the detected object, and the computer analyzes and treats these two digital images, calculates the equivalent atom sequence numbers of the object to distinguish organic matter, inorganic matter and mixture and displays in different colors.

Description

Technical field [0001] The invention relates to a social public safety inspection equipment, in particular to a portable dual-energy X-ray inspection device. Background technique [0002] Portable X-ray inspection devices are mainly used in customs, airports and other public places to inspect metal weapons, explosives, drugs and other contraband hidden in luggage packages and other items. [0003] The existing various portable X-ray inspection devices generally use traditional X-ray imaging technology, which is recognized by the gray level and graphic contour of the transmission image of the inspected article. The gray level and graphic contour of the transmission image are determined by X-ray transmission. It is made by superimposing perspective images of various objects in the path. [0004] For metal contrabands such as guns and knives hidden in clothes and books, because their density is much higher than that of clothes and books, and they have obvious shapes, traditional X-r...
