Baggage inspection machine is an electronic device that completes the inspection by sending the checked baggage to the X ray inspection channel with the aid of the conveyor belt. Generally used in airports, railway stations, bus stops and so on. After the passengers enter the station, the luggage, luggage bag or some large woven bags are placed on the security tester. The passengers are sent by the conveyor belt to receive X light inspection. Once the suspected dangerous items appear, the passengers who are in charge of security will ask the passengers to open their luggage for inspection, and the passengers will only need more than ten seconds to complete the security check.
Development process / baggage security machine
Since 1970s, with the rapid development of the aviation industry, aviation and airport safety have been gradually paid attention to. In order to prevent passengers from carrying weapons on the aircraft and avoid hijacking or dangerous events, metal detection doors have become the necessary security equipment for all airports. Metal detection technology has also been applied to new applications, and then gradually develop to The application of other fields.
In 80s, the cases of prison violence have been rising in a straight line. How to prevent and prevent the cases of violence early and effectively is the most important thing in the prison management. While relying on the police to strengthen the management of the prisoners, the metal detection door has become the United States, the UK, Belgium and other developed countries. Security inspection equipment,
After 90s, the rapidly rising electronic manufacturing industry became the favorite of the era. In order to reduce the loss of products and end the embarrassment between employees and companies, such as mobile phone factory, chip factory and other high price products or manufacturers, the most needed metal detection door to prevent the loss of property.
However, at this time the simple channel metal detection door can not fully meet the requirements of security inspection, security personnel need to be able to accurately determine the location of metal items security products. So the multi location metal detection technology is conceived, and its birth is another change in the history of the security gate. It turns out that the single magnetic field has become a multiple magnetic field which is now overlapping and relatively independent, and then according to the principle of ergonomics, it is divided into several sections to make it corresponding to the human body. The metal detection door forms a relative area, so that the metal detection door has the function of alarm location.
Working principle / baggage security machine
When the luggage enters the X - ray inspection channel, the package detection sensor will be blocked, the detection signal is sent to the system control part, the X ray trigger signal is generated, and the X ray ray source is triggered to launch the X ray beam. A beam of X ray beams passing through a collimator passes through the checked items on the conveyor belt, and the X rays are absorbed by the inspected items, and then the double energy semiconductor detectors installed in the channel are bombarded. The detector transforms the X ray into a signal. These very weak signals are amplified and sent to the signal processing box for further processing. These signals are displayed through the display screen. "No matter how many layers of packages, X rays can penetrate, and display objects in packages one after another."
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.
