In today's world, there are conflicts and turmoil in many countries, and the influence of terrorists, extremists, separatism and many other disturbing factors has brought severe challenges to the social security and security of public places in our countries. In these places, people are numerous and complex, and criminals often carry banned items such as knives, guns, bombs, etc., waiting for opportunities to commit crimes, causing heavy casualties and property losses, as well as extremely bad social effects.
In order to minimize the occurrence of such bloodshed terrorist incidents, it is necessary to rely on scientific management with scientific and effective management tools. Security gates and security screening machines are officially one of its most effective tools. It has been widely used in important places such as various agencies and units to prevent terrorist attacks. After a long period of practice, it has been proven to be the most effective. One of the security tools.
Security inspection machines are widely used in airports, railway stations, bus stations, government office buildings, embassies, conference centers, convention centers, hotels, shopping malls, large-scale events, post offices, schools, logistics industries, industrial inspections and other places.
principle:
The "eyes and golden eyes" of the security inspection machine are all realized by X-rays. It is an electronic device that uses a conveyor belt to send checked luggage into the X-ray inspection channel to complete the inspection. Baggage entering the X-ray inspection channel will block the package detection sensor, and the detection signal will be sent to the system control part to generate an X-ray trigger signal to trigger the X-ray source to emit an X-ray beam. A fan-shaped X-ray beam passing through the collimator passes through the inspected item on the conveyor belt, the X-ray is absorbed by the inspected item, and finally bombards the dual-energy semiconductor detector installed in the channel. The detector converts X-rays into signals. These weak signals are amplified and sent to the signal processing box for further processing.
X-rays are electromagnetic waves that can penetrate opaque objects such as wood, cardboard, and leather. The security detector can present images of different colors on the screen according to the degree of absorption of X-rays by the object. Simply put, orange represents organic matter, such as food, plastic, etc.; books, ceramics, etc. are displayed as green; metal is displayed as blue. At this time, the security inspector can quickly check the fluoroscopy image of the X-ray scan, and can judge whether there is contraband with the rich experience.
Security inspection machines are generally used in semi-outdoor environments such as subways, auto shows, convention centers, etc., and may be used in high, low temperature and high humidity environments, and require 24H uninterrupted and stable work. There are many kinds of use sites, and the interference is relatively large. The X-ray machine has electromagnetic interference, so the requirements for the industrial computer are as follows:
High and low temperature resistance, more than 70% of regions and countries in the world require stable use at -20～55℃.
Reinforce the anti-vibration, and some sites need to arrange temporary security checks.
Strong anti-interference, free from electromagnetic interference from the environment and the equipment itself.
The performance is better and the image is clear.
The advantages of Anrecson industrial computer:
Small size, easy to install inside the equipment.
The power supply adopts a wide temperature power supply, which can be used at -20～70℃. Most power supplies cannot be cold-started at -10℃.
Mechanical hard drives and solid state drives are selected according to the on-site use environment. The mechanical type is suitable for environments with a temperature of -5 to 55 degrees Celsius, and the solid state drive is suitable for sites below -5 degrees Celsius.
Good anti-interference, solid materials for the chassis and main board, and use good anti-interference materials and materials.
The configuration is cost-effective and the image effect is good.
The solid materials and design of the industrial computer are for long-term, uninterrupted operation.
