Safety detection method for liquid

Abstract

A safety detection method for liquid includes the following steps that a prohibited liquid database server is built; data information of various kinds of nationally regulated prohibited liquid is acquired to form a reference library; a detection device is built; detection and data acquisition of to-be-detected liquid are performed, and finally pre-warning is performed.The safety detection method for liquid is simple and clear in step, safety detection can be performed on sealed solutions, accuracy is high, detection can be performed without sample extraction, passing of pedestrians is made convenient, and lots of unnecessary trouble is reduced for security personnel.

Description

technical field [0001] The invention relates to the technical field of human body safety inspection, in particular to a method for safety inspection of liquids. Background technique [0002] In recent years, public security issues have increasingly attracted the attention of people all over the world, and higher requirements have been put forward for the reliability and intelligence of anti-terrorism, security detection and public security investigation systems. There are metal security gates, hand-held metal security detectors, luggage security detectors, millimeter wave security detectors and back scattered security detectors at home and abroad. [0003] The first-generation security inspection products are represented by metal security doors and hand-held metal security detectors. This type of equipment detects metal objects through magnetic field technology, and can only detect metal objects, and cannot effectively distinguish and detect non-metal objects. Without an im...

AI Technical Summary

Problems solved by technology

[0003] The first generation of security inspection products are represented by metal security doors and hand-held metal security detectors. This type of equipment detects metal objects through magnetic field technology, and can only detect metal objects, and cannot effectively distinguish and detect non-metal objects.

No imaging system, unable to locate suspicious objects

[0004] The second-generation security inspection products are represented by luggage security detectors, millimeter wave security detectors and back-scattered security detectors. Among them, luggage security detectors use high-dose X-ray irradiation to clearly detect suspicious objects in luggage, which is fast and extremely large. It changed the current situation of security inspection at that time, but with the improvement of criminal methods, this type of equipment cannot be used for human inspection due to dose and design reasons

[0005] At present, in public places such as stations and ferries, especially airports, it is generally necessary to check the luggage and persons of pedestrians to prevent pedestrians from carrying prohibited items. When detecting liquids, some liquids are sealed in sealed containers, or In a sealed plastic bag, it is not easy to extract samples during testing, so that it will not pass the security check, which will cause trouble for pedestrians and a lot of trouble for security personnel
