How does an X-Ray Baggage Scanner Work?
Whenever the Spring Festival travels, no matter it is the railway, road or air transport, it has ushered in unprecedented busyness. All departments are busy dealing with the peak passenger flow that has arrived. The security inspection of such a crowded area in the station is inevitably the top priority. Now we are going to introduce X-Ray Baggage Scanner.
X-Ray Baggage Scanner is called “Check the dangerous instrument”. The working principle is to use a small dose of X-rays to illuminate the articles for inspection, use a computer to analyze the transmitted rays, and analyze the properties of the penetrated articles according to the changes in the transmitted rays. The image on the display is a computer-simulated image that highlights items of dangerous nature (differentiated by color). Many everyday items will be ignored and will not be displayed. There is no harm to digital products, but it will be very harmful to the human body. If human tissue is exposed to X-rays, irreversible lesions will occur. However, everyone does not need to worry about it. The X-ray machine body and lead curtain can ensure that the X-ray leaks as small as possible, but don't stay too long beside the machine for safety purpose.
There are generally four inspection methods in the safety inspection: one is the railway Baggage Scanner, which is mainly used to check the passenger's luggage items. After passing the inspection, the staff posted the “XX Airport Baggage Security” sticker on the baggage before proceeding with the check-in procedure or carrying it on board; the second is the metal detection door for the physical examination of the passenger. Mainly check whether the passenger carries the forbidden items; the third is the magnetic detector, also called the hand-held metal detector, which is mainly used for the close inspection of the passengers; the fourth is the manual inspection, that is, the security inspection staff manually check the passenger luggage and Male and female inspectors perform a body search and so on.
At each entrance to the pit stop, there is a mysterious guy. This is the X-ray security inspection equipment. All passengers are required to put down the big bag and check it through the security instrument.
The X-Ray Baggage Scanner used in the railway station is similar to the security equipment at the airport and the bus station.
After the passenger enters the station, the luggage, luggage bag or some large woven bags and other luggage are placed on the security instrument, transmitted through the conveyor belt, and subjected to X-ray inspection. No problem, the passengers take the baggage away. In the event of a suspected dangerous item, the person in charge of the security check will ask the passenger to open the baggage for inspection, and the general passenger can complete the security check within ten seconds.
The principle of the X-Ray Baggage Scanner is that the security device is an electronic device that performs the inspection by means of a conveyor belt to carry the inspected baggage into the X-ray inspection channel. The baggage enters the X-ray inspection channel, which blocks the package detection sensor, and the detection signal is sent to the system control section to generate an X-ray trigger signal, and the X-ray source that emits the X-ray emits the X-ray beam. The X-ray beam passes through the object to be inspected on the conveyor belt, and the X-ray is absorbed by the object to be inspected, and then the semiconductor detector mounted in the channel is bombarded. The detector converts the X-rays into signals, which are amplified and sent to the signal processing chassis for further processing. These signals are processed and displayed through the display. “Whether there are several layers in the package, X-rays can penetrate and display the contents of the package layer by layer.”
The XRay Baggage Scanner is not a display, but it actually takes up the task of guarding the railway security. Some passengers are not clear about dangerous goods, and many people bring them to the car. Therefore, it is often possible to fill a basket under the table near the east security instrument with colorful bottles and jars. There are hair gels, air fresheners, nail polishes, etc. in the basket, sometimes with tools. These are checked by the security instrument. Among these detected dangerous goods, chemical dangerous goods account for 80%. Many people think that only some controlled tools are dangerous goods that are prohibited from being carried on the train. It is not known that chemical dangerous goods are more lethal. "These bottles of hair spray, air fresheners, etc. are compressed gas and liquefied gas. When heated, when the pressure inside the bottle rises above the pressure limit of the container, it will cause an explosion." What is the security instrument?
Check out these dangerous items?
After X-ray inspection, the contents of the baggage will display a general shape on the display and display in yellow, green, black, and so on. Generally, yellow items are organic, such as plastics and foods. They are safe, while green and black items need to be noted. If there are more green or black objects, or they are in the shape of a dagger or a knife, the passengers will be asked to open the baggage check. Flammable, explosive, toxic, corrosive, radioactive, infectious disease pathogens, guns, ammunition, controlled knives, etc. are strictly prohibited from entering the station and will be confiscated once found. Kitchen knives, table knives, fruit knives, handicraft knives, scissors, steel (iron) hoes, axes, hammers, and other sharp objects and blunt instruments should not be carried with them.
