Trace explosive and drug detector

Abstract

A trace explosive and drug detector comprises an outer layer, an outer middle layer, an inner middle layer and an inner layer.The inner middle layer and the inner layer are attached and tightly compressed into a whole layer.The outer middle layer detachably covers the inner middle layer, and the outer layer detachably covers the outer middle layer.The outer layer is a full-silver fiber knitted fabric layer made of composite fibers formed by fusing silver ions and common fabric, the full-silver fiber knitted fabric layer has good air permeability and has antibacterial function, the anti-radiation shielding value is not lower than 70 DB, static electricity can be eliminated, and shielding performance is stable.The outer middle layer is a deep sea precipitation fabric layer which is a fabric layer formed by blending a metal fiber or silver fiber material and ginned cotton fibers, the metal fiber or silver fiber material is developed through the deep sea precipitation technology, the micronaire value of the ginned cotton fibers ranges from 4.1 to 4.3, and the effective radiation shield value is not smaller than 80 DB.

Description

technical field [0001] The invention relates to the technical field of safety inspection detector equipment, in particular to a trace explosive drug detector. 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. Common security inspection equipment at home and abroad include metal security doors, hand-held metal security detectors, luggage security detectors, millimeter-wave security detectors, and back-scattered security detectors. They are roughly divided into two generations of products according to their production time and functions: [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...

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, the dose of this type of equipment has always been at the safe node of the acceptable dose for the human body, and the electromagnetic radiation of millimeter waves will destroy the bioelectric field of the human body, which will affect heart patients with pacemakers, and there is a huge potential safety hazard

[0006] During the on-site operation, the staff in the security inspection place are faced with long-term contact with the security inspection equipment, and the distance is relatively close, which will cause great harm to the body
