Raman spectrum non-invasive customs detection device

Abstract

The invention belongs to the technical field of customs detection equipment, and discloses a Raman spectrum non-intrusive customs detection device which is characterized in that a conveyor belt is fixed in the middle of a supporting frame, a detection bin is fixed on the upper side of the supporting frame, and openings matched with the conveyor belt are formed in the two ends of the detection bin respectively; the detection module and the main control module are both fixed on the inner side of the detection bin, the detection module is used for collecting Raman spectrum data of a to-be-detected article by using a Raman spectrometer, and the Raman spectrometer is mounted towards the conveyor belt; the cloud processing module is connected with the main control module and the monitoring terminal through wireless signals. According to the present invention, the type and the component of the to-be-detected object are detected through the Raman spectrum, the method is the spectrum measurement technology for analyzing the molecular structure by measuring the scattered light with the frequency different from the excitation light frequency based on the Raman scattering effect, and the method has characteristics of high chemical specificity, accurate analysis and identification of the material component, and wide application prospect. Meanwhile, the whole structure is simple, the cost is low, and the hidden danger of X-ray leakage is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of customs detection equipment, and in particular relates to a Raman spectrum non-invasive customs detection device. Background technique [0002] At present, under the situation of my country's rapid economic growth and rapid development of foreign trade, customs inspection tasks are numerous. The existing customs inspection methods are divided into five categories: first, unpacking inspection, second, appearance inspection, third, machine inspection, fourth, thorough inspection, and fifth, random inspection. All inspections except machine inspections are manual inspections, which are highly dependent on personnel experience. The outdated inspection methods also directly affect the effect of customs inspections. [0003] The existing common customs inspection method is the X-ray radiation imaging detection method, which uses X-ray radiation imaging inspection equipment to scan the goods, and analyzes and c...

Problems solved by technology

[0005] (1) The existing customs detection devices are bulky, occupy a large space, and have high equipment costs, as well as the hidden danger of X-ray leakage

[0006] (2) A single X-ray radiation imaging device can only alarm the material properties of suspicious substances, and cannot give the substance name on site. At the same time, it cannot effectively distinguish plastics, jewelry, rare earths and other substances, and cannot perform re-inspection for substances that need to be re-inspected.
