Whenever it comes to Spring Festival, no matter railway, highway or air transportation, it has been unprecedentedly busy. Departments are busy coping with the arrival of the peak passenger flow. And the station security check work is the top priority. The station security tester is to be introduced today.
The station security device is called the "danger lookup". The principle of the work is to use a small dose of X ray to irradiate the items, use the computer to analyze the transmitted rays, and analyze the properties of the penetrated items according to the changes in the radiation. The image on the screen is a computer simulated image, which highlights the dangerous items (with color distinction). Many daily items will be ignored and will not be displayed. It is not harmful to digital products, but it will be very harmful to human body. If human tissues are exposed to X rays, irreversible lesions will occur. But you do not need to worry, X ray machine body, lead curtain can ensure the maximum extent of X ray as small as possible leakage, but it is best not to stay for too long next to the machine, always a little leak.
There are four kinds of inspection methods in safety inspection: the first is the X ray security inspection equipment, which is mainly used to check the baggage items of passengers. After the inspection, the staff on the luggage on the luggage "XX airport baggage inspection" adhesive strips, and then can be checked in the check-in procedure or carry on the plane; two is the detection inspection door, used for the passenger's physical examination, mainly check whether passengers carry forbidden goods; three is a magnetic detector, also called a portable detector, It is mainly used for close - up inspection of passengers; four is manual inspection, that is, the manual inspection of passenger baggage by the security inspectors and the search and inspection of men and women inspectors respectively.
At the entrance to each entrance, there is a mysterious guy, this is the X light security instrument, all passengers are asked to put down the bag, and check through the security tester.
The security instruments used in the railway station are similar to the safety inspection instruments at the airport and the automobile station. After the passengers enter the station, the luggage, luggage or some large woven bags are placed on the security instrument, and the passengers will take the baggage through the conveyor belt to receive X light inspection. Once the suspected dangerous goods appear, the people in charge of security check will ask the passengers to open their luggage for inspection, and the passengers can complete the security check in more than ten seconds.
Speaking of the principle of the security inspection device, the security detector is an electronic device that completes the inspection with the aid of the conveyor belt to send the checked baggage to the X ray inspection channel. When the luggage enters the X - ray inspection channel, the package detection sensor will be blocked. The detection signal is sent to the control part of the system. The X ray trigger signal is generated, and the ray source that triggers the X ray emission is emitted by the X ray beam. The X ray beam passes through the detected object on the conveyor belt, and the X ray is absorbed by the detected object, and finally bombarded the semiconductor detector installed in the channel. The detector turns the X - ray into a signal, and these very weak signals are amplified and sent to the signal processing box for further processing. The signals are processed and displayed on the display screen. "No matter how many layers of packages, X rays can penetrate, and display objects in packages one after another."
Identify dangerous items by different colors
The optical security device is not a display, but a real safety guard. Some passengers are not clear about dangerous goods, and they carry many people who come in. So it is often filled with colorful bottles and cans in a basket near the desk near the East Security Tester. There are gums, air fresheners, nail polish, and sometimes even knives in the basket. All these are checked by the security tester. Of these dangerous products, chemical dangerous goods account for 80%, and many people think that only some control tools are dangerous products that prohibit the carrying of the car, and the chemical dangerous products are more lethal. "These bottles of hair gel, air freshener and so on are some compressed gas and liquefied gas, after heat, when the pressure in the bottle is higher than the pressure limit of the container, it will cause the explosion." How did the security device check out the dangerous articles?
After X light detection, the items in the luggage will display the general shape in the display and display yellow, green, black and so on. Generally yellow items are organic, such as plastic, food and so on, it is safe, and green, black items need attention, if green or black objects are more, or dagger, knife shape, it will require passengers to open luggage inspection. Inflammable, explosive, toxic, corrosive, radioactive, infectious diseases, firearms, ammunition, control tools and other articles are strictly prohibited from entering the station, and will be confiscated once it is found. The kitchen knife, knife, fruit knife, handicraft knife, scissors, steel (iron) file, axe, hammer and other sharp tools and blunt instruments should not be carried with them. They should be checked in all luggage.
