Brief Introduction of X-ray Bag Scan Equipment


X-ray bag scan equipment is widely used in the train station, bus passenger terminal, airport to scan bags. It is so popular that you can see it every time you go for traveling or are on business trip. And those bags required to be checked must be radiated by X-ray. After X Ray inspection supplier, radiation which is not absorbed will be collected in the area array of image detector. X-ray bag scan equipment outputs ultralow electrical level current which needs adjustment of special signal. In order to show the stuff which is being scanned correctly, it uses high resolution data transducer to attain essential resolution. And this kind of signal adjustment is included in the data collection, just the same as the situation of analog-digital converter attaching electricity to voltage.
The kernel system of X-ray bag scan equipment includes DSP processor, amplifier, converter, and power management system and temperature sensor. DSP processor is used to refactor image formation, and uses image detector to receive signal and then generate the image of the scanned bag. Amplifier amplifies low or intermediate frequency signal, while converter switches integration electricity to voltage, which can transform the low level electric current to the data information processed by computing element. In addition, the most basic system of X-ray bag scan equipment is power management system, which is used to control system power supply. And usually there are many passageways in the system, which results in the rising environment temperature. And the temperature sensor will cool the system and prevent from extremely high temperature.
The advantages of metal detector door are obvious. The wave length of X-ray is very short, resulting a extremely high frequency. Also, the radiation sent by X-ray bag scan equipment is synchronous. X-ray spectrum consists of two parts: continuous spectrum and identify spectrum. And the identify spectrum is generated because of the transition of target element inner electron, and each element has its own identify spectrum, which reflect the shell structure of atom. This kind of synchronous radiation can produce high and continuous x-ray spectrum. It has become the most significant radiation source. Moreover, the most superior advantage of X-ray bag scan equipment is its strong penetrating power. X-ray has high penetrating power, and it can pass through many materials which are opaque to visible light, such as ink paper, wood, etc. This invisible to the naked eye ray can make many solid materials emit visible fluorescence. And the energy of x-ray is stronger with a shorter baggage scanner price. According to this principle, different kinds of X-ray bag scan equipment’s are made aiming at different uses.
X-ray bag scan equipment has several characteristics. It has sound-light alarm, so when it detects some dangerous materials, it will sound and send alarm light signal. Also, it is connected to LAN, which allows several terminals check bags at the same time. And the ray X-ray bag scan equipment emits is controlled automatically, which prevents fault.
X-ray bag scan equipment is useful and significant to ensure human being’s safety in many situations. With its bright prospect, I am sure that baggage inspection must be developed and more advanced.
