How does the security check device work?

Behind the rapid development of today's social economy, the domestic security environment is often affected by terrorists, Western forces, separatism and many other unsafe factors, which poses a serious threat to the safety and security of public places and social security in China. In order to improve the safety of public places, safety inspection equipment has been widely used, and has been proved to be one of the most effective security inspection devices. So, how much do you know about safety inspection equipment? Next, we briefly introduce the security inspection devices and related working principles. Hope to help you better understand the security inspection devices.

The main points are as follows:

♦ What is safety inspection equipment?

♦ Working Principle of Safety Inspection Equipment

♦ Present Situation and Prospect of Safety Equipment

♦ Conclusion

What is safety inspection equipment?

As the name implies, security inspection device is a kind of equipment that can carry out relevant safety inspection and carry out investigation and treatment of potential safety hazards. Such equipment includes：safety door, hand-held metal detector, safety X-ray machine, dangerous liquid detector, vehicle video inspection mirror, metal detector in shoes, hose endoscope, etc. Because of its special performance, safety equipment has been widely used in public security anti-terrorism, airports, courts, procuratorates, stations, stadiums, exhibition centers, entertainment venues and other places requiring safety inspection.

Working Principle of Safety Inspection Equipment

There are many kinds of existing security inspection devices, and the working principle of the corresponding equipment is also different. The following is a brief introduction to the working principle of some security inspection devices.

(1) Safety door

Safety door is a kind of detection device used to detect whether people carry prohibited metal items, also known as metal detection door. Mainly used to check hidden metal objects, such as guns, control tools and other prohibited items, into complex public places, because the security gate according to the weight of prohibited metal items, quantity or shape of pre-set parameters. When the inspected person passes through the security door and the number of prohibited metal articles on him exceeds the total amount set by the security gate, the security gate immediately alarms and displays the metal location causing the alarm so that the security personnel can find the metal articles that the person carries in time.

(2) Safety Inspection Machine

X-ray security machine mainly scans suitcases and articles outside the human body to find hidden dangerous goods. Through the conveyor belt, the checked luggage is sent to the X-ray inspection channel to complete the inspection of electronic equipment. Luggage enters the X-ray inspection channel, blocks the package detection sensor, sends the detection signal to the control part of the system, generates the X-ray trigger signal, triggers the X-ray source to emit X-ray beam. The sector X-ray beam passing through the collimator passes through the detected object on the conveyor belt. The X-ray is absorbed by the detected object, and finally bombards the dual-energy semiconductor detector installed in the channel. The detector converts X-rays into signals, which are amplified and sent to the signal processing cabinet for further processing. This technology is widely used in the public safety inspection of contraband.

Present Situation and Prospect of Safety Equipment

With the rapid development of social economy, security inspection devices has become one of the indispensable things. So, what is the current situation and development prospects of safety inspection equipment?

(1) The function of safety inspection equipment is irreplaceable.

As high-risk equipment, especially in places with dense personnel (such as airports, customs, stations, public security organs, etc.), security inspection devices can carry out safety inspection on personnel, goods, places and other equipment. It plays a unique and special role in preventing and curbing explosions, shootings, murders and other cases, especially terrorist activities.

(2) The original application market is still growing rapidly.

In recent years, the most important application fields of them are civil aviation airport, urban rail transit, railway and highway passenger transport, public security law and other departments. Firstly, from the point of view of the airport security market, the rapid growth of China's security equipment market is driven by the demand for airport security. Secondly, from the point of view of the security inspection devices market of urban rail transit, with the improvement of the safety level of urban rail transit, the application of safety inspection equipment in urban rail transit stations is gradually increasing.

(3) The new field of security inspection application is expanding.

With the gradual deepening and comprehensive development of safe city construction, more and more attention has been paid to the application of safety inspection technology and equipment, especially in recent years, more and more terrorist incidents have occurred.
