Problems solved by technology

[0005] However, the inspection equipment assembled in this way takes up a lot of space and weight, high cost, laborious disassembly and assembly, and inconvenient to use
In particular, the internal parts of the inspection equipment assembled in this way are relatively large and scattered, which increases the volume of the equipment itself, the radiation protection area, and the difficulty of design and processing.

Embodiment Construction

[0031] figure 1 A dual-channel transmission inspection device and a method of use thereof according to an embodiment of the present invention are schematically shown. The dual-channel transmission inspection equipment in this embodiment mainly includes a double-fan beam X-ray machine 31 , a first inspection channel 10 and a second inspection channel 20 . The double-fan beam X-ray machine 31 as the core component is arranged on the top of the device. The double fan beam X-ray machine 31 can generate two X-ray fan beams with corresponding orientations according to system requirements. The first inspection channel 10 includes a first detector 11 and a first conveying device 13 . When the first luggage 12 is checked, the first luggage 12 is placed on the first conveyor 13 . The second inspection channel 20 includes a second detector 21 and a second conveying device 23 . When the second luggage 22 is checked, the second luggage 22 is placed on the second conveyor 23 . The baf...

Abstract

The invention discloses a transmission inspection device. The transmission inspection device comprises two inspection channels and a dual-fan-shaped-beam X-ray machine arranged between the two inspection channels, wherein the dual-fan-shaped-beam X-ray machine is used for generating two mutually independent X-ray fan-shaped beams, transmitting one X-ray fan-shaped beam to one inspection channel and transmitting the other X-ray fan-shaped beam to the other inspection channel so as to respectively carry out transmission scanning of inspected targets in the two inspection channels; an included angle is formed between field angle center lines of the two X-ray fan-shaped beams, so that transmission scanning in the two inspection channels is free of mutual interference. The invention also discloses a method for inspecting the inspected targets by using the transmission inspection device.

Description

technical field [0001] The present invention generally relates to a transmission inspection device and an inspection method, and more particularly relates to a transmission inspection device and an inspection method using X-ray transmission imaging technology. Background technique [0002] X-ray transmission imaging technology has good penetration and high spatial resolution, especially sensitive to high atomic number substances such as copper and iron, with clear imaging and good identification effect. Therefore, X-ray transmission imaging technology has been widely used in security inspections such as luggage items. [0003] In order to improve the inspection efficiency and pass rate of luggage items, two or more sets of X-ray transmission inspection equipment of the same structure are usually assembled and combined for use. Figure 8 It is a schematic diagram of the overall structure and usage method of the dual-channel transmission inspection equipment in the prior art. ...
