Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] figure 1 It is a three-layer organization chart of the software system architecture of the channel-type dual-view X-ray liquid article safety inspection system of the present invention. As mentioned above, there are a total of 12 modules, which are distributed in the data processing layer, logical analysis layer, and interface display layer in terms of organizational hierarchy. When in the collection-detection-display working mode, the present invention triggers the data processing layer to work from the bottom layer, transmits the result to the logic analysis layer, and then transmits the analysis result to the interface display layer for display; when in the image processing working mode, the present invention The work is triggered by the upper layer, the button of the interface display layer is triggered, and the command is passed to the lo...

Abstract

The invention discloses a channel type two-viewing-angle X-ray liquid substance safety check system which comprises a software system architecture and a hardware architecture, wherein the hardware architecture is a channel type two-viewing-angle X-ray liquid substance safety check device. According to the invention, channel type two-viewing-angle X-ray machine equipment and two computers are utilized, the software system of three-layer structures, namely a lower data processing layer, an intermediate logical analysis layer and an upper interface display layer, calculates substance characteristics of the liquid substance according to a two-viewing-angle image, wherein in the software system architecture, the data processing layer consists of seven functional modules, the logical analysis layer consists of four modules, and the interface display layer is composed of one module. The system has the advantages that liquid is supported and allowed to be arranged in a tray in a cross mode with non-liquid, distance between the liquid is not needed to be kept, a conveyor of equipment can reversely operate and perform liquid detection, and the condition that a conveyor belt of two-viewing-angle equipment reversely operates can be avoided.

Description

technical field [0001] The invention relates to a channel-type dual-view X-ray safety inspection system for liquid articles, belonging to the technical field of X-ray digital imaging safety inspection. Background technique [0002] Since the "9.11" incident, inspection of liquid items has gradually become a hot issue in the field of safety inspection. Due to the wide variety of liquid items and different packaging, it is becoming more and more difficult to quickly and accurately identify the hazards of various liquid items. . Since 2010, various aviation safety authorities in the world have researched and formulated the standards for carrying liquid items on board the aircraft. The schedule for carrying liquids on the plane has also been finalized many times. The European Union has issued EU standards. Two standards, Standard 1 and Standard 2, were proposed for the difficulty of detecting liquid explosives, and the capabilities of equipment are divided into four grades, A...
