Introduction of Two Common Security Inspection Devices

Once speaking of security inspection, we tend to think of personal security inspection and cargo security inspection at public place, such as the airport, customs, and quay etc. As a matter of fact, in addition to these places, security inspection device are often needed in other large-scale activities, like the Olympic Games, the Universidad, the national games, exhibitions, celebrations and so on. Next is an introduction of two common security inspection devices, baggage inspection and X Now there are many different types of security inspection device, like walk-through metal detectors, handheld metal detectors, X-ray luggage inspection, drug explosives detectors, etc., and they are widely used in places such as subway station, airport and other places where need to guarantee the personal safety. ray inspection machines.
Walk-through metal detectors
Walk-through metal detectors are mainly used as security inspection devices in large person flow situations to detecting metal materials hidden on the body. A few high-grade walk-through metal detectors on the market can alarm immediately when the inspector pass through the door, once detected that the result value is above the preset parameter of metal materials’ weight, quantity or shape, and display the area which caused this alarm. There is no doubt that this security inspection device is very efficient in helping lightening the workload of security personnel. Special metal detector door, which are widely used in factories, are usually applied to identify the existing of metal items. Then, if productions are brought out of factory illegally, we should locate and call the police. What’s more, the best walk-through metal detectors nowadays can be even applied to detect paper clip sized metal material.
X ray inspection machines
X ray inspection machines are an X Ray inspection supplier inspection device using X ray’s ability to transmission and scatting through objects to do the check work. The luggage enters into the inspecting channel, and this will trigger a package detecting sensor, then the sensor send detecting signal to system controlling section, producing a trigging signal of X ray.
Once receiving this signal, the baggage scanner price fixed in the security inspection device will emitting an X ray beam right away. This fan-shaped beam of X ray after collimator transmission through the detected object, and the target object will absorb the X ray, finally the weakened X ray bombard the dual energy semiconductor detector installed in the channel. Dual energy semiconductor detector will transform the received X ray into electrical signals. After amplifying, those electrical signals will be sent to the signal processing section for further processing and form an image on the connected computer, and security personnel can make judgments whether it contains metal material according to this image. The above is the general working principle of this type of security inspection device. And the image processing technology is improving with the development of modern society, which will bring more accurate security inspection results to us. It is reasonable to believe security inspection device will be more reliable and intelligent in the future.
