Body security machine
The human body security machine is a safety inspection device used in a specific place to check whether prohibited items and dangerous goods are carried under human clothing and in the body. The following is a detailed introduction to the human safety inspector:
一、Working principle
The working principle of the human safety inspector is varied, mainly including the following technologies:
X-ray penetration technology: The use of X-rays to penetrate the substance, through the control unit to process the received signal to generate images. When the X-ray passes through the human body, part of the X-ray will be absorbed by the body tissue, and part is reflected. The control unit determines the specific structure of the human body by calculating the number of rays reflected back, and displays it on the display terminal.
Metal detection technology: using low-energy electromagnetic waves to penetrate the human body, if the surface of the human body carries metal items, it will interfere with electromagnetic waves, making the electromagnetic waves received back change, so as to determine whether the human body carries metal items.
Imaging technology: Scans the body by generating and receiving X-rays or millimeter waves to obtain an image of the body, which can show the outline of the body's surface and the objects it carries.
Terahertz wave technology: Using the characteristics of the body's spontaneous radiation of terahertz waves, to achieve terahertz imaging.
Infrared composite technology: The use of the maximum intensity of the human spontaneous radiation in the infrared band for body temperature composite detection, can complete the non-contact security and body temperature screening at the same time.
二、Functional&Feature
High efficiency: The human safety inspector can quickly scan the human body, improve the efficiency of security inspection.
Accuracy: It can accurately identify prohibited and dangerous items carried by the human body, such as knives, guns, bombs, etc.
Safety: Most human safety inspectors are designed with safety in mind, such as using low-dose X-rays, non-contact testing, etc., to reduce the potential impact on human health.
Ease of use: Easy to operate, convenient security personnel to use.
三、Application
Human safety inspectors are widely used in a variety of places that need to ensure public safety, such as:
Civil aviation, rail and road traffic: used to carry out security checks on passengers to prevent the carrying of prohibited items on board or on board.
Law enforcement agencies: such as police, customs, etc., used to conduct security checks on suspects or passengers.
Events and activities: such as sports games, concerts, exhibitions, etc., are used to carry out security checks on the audience to ensure the safety of the activities.
Civilian places: such as schools, hospitals, shopping malls, etc., are used for security checks on people entering the places to prevent dangerous goods from entering.
四、Matters needing attention
Privacy protection: When using the body safety inspector, the privacy of the person being inspected should be respected and their personal information should be avoided.
Radiation safety: For human safety inspectors using radiation technology such as X-rays, the radiation dose should be strictly controlled to ensure that it is used within a safe range.
