Safety detection method and device of liquid

Abstract

The invention discloses a safety detection method and device of liquid. The safety detection method comprises the following steps of: scanning a bar code on a vessel containing detected liquid, and searching liquid information and vessel information corresponding to the bar code in a database; acquiring first liquid information and first vessel information of the detected liquid by adopting double energy rays; when the vessel information corresponding to the bar code is matched with the first vessel information, comparing the liquid information corresponding to the bar code with the first liquid information; and when the vessel information corresponding to the bar code is not matched with the first vessel information, searching second vessel information matched with the first vessel information in the database, acquiring second liquid information which reflects an actual state of the detected liquid, and comparing the liquid information corresponding to the bar code with the second liquid information. The safety detection method has higher detection precision, and the safety detection device is more convenient to operate.

Description

technical field [0001] The invention relates to a safety detection method and a device thereof, in particular to a liquid safety detection method and a device thereof. Background technique [0002] CT technology is computerized tomography technology. X-ray CT technology refers to X-ray computed tomography technology. Generally, a CT system includes a radiation source, a detector, a data collector, a computer, and the like. CT technology can be used to carry out safety inspection on liquids. Domestic Nuctech and the First Research Institute of the Ministry of Public Security have related technologies and products. The above-mentioned patents all use single-energy or dual-energy CT technology to obtain physical characteristic values ​​such as density and atomic number of the liquid, and then judge the safety of the liquid. [0003] Using single-energy CT technology can only obtain one-dimensional density information, and the detection accuracy is low. [0004] The two-dime...

AI Technical Summary

Problems solved by technology

The detection accuracy of common plastic, glass, ceramics, metal aluminum and other containers and packaging liquids is relatively high, but the detection accuracy of high-density metal (such as metal iron) container packaging liquids is relatively low, especially for the detection error of the effective atomic number bigger

[0005] However, at present, there are no related products and technologies that use barcode technology to assist liquid detection.
