As an important tool for the safety management of the college entrance examination room, the working principle of the intelligent security gate is based on special technical means, which is designed to comprehensively, quickly and accurately detect the illegal items carried by the candidates, prevent cheating, and ensure the safety of the examination room. Here's a closer look at how smart security gates work.
First of all, the smart security gate uses metal detection technology. This technique uses the principle of electromagnetic induction to determine whether a test taker is carrying a metal object by emitting an electromagnetic field and detecting whether it is blocked or reflected by a metal object. When candidates carry metal objects, such as mobile phones, calculators, cheats, etc., it will interfere with the propagation of electromagnetic fields, so that they will be detected in time by the smart security gate. This metal detection technology is characterized by high sensitivity and accuracy, which can effectively detect metal objects carried by test takers and prevent cheating.
Secondly, the smart security gate also uses eddy current detection technology. The items on the examinee's body are scanned and the data of the items is generated, so as to realize the detection of non-metallic items. The smart security gate can comprehensively and quickly check the packages, books and other items carried by the candidates, and timely find the equipment or illegal items that may be used for cheating, providing reliable data support for the security check.
In addition, the smart security gate is equipped with an intelligent identification system. This system uses artificial intelligence and image recognition technology to automatically identify and analyze detected items to quickly determine whether they are illegal or dangerous. Through the intelligent identification system, the intelligent security gate can quickly and accurately identify candidates carrying illegal items, and send out an alarm in time to notify the invigilator to deal with it, so as to effectively prevent cheating and the carrying of dangerous goods.
To sum up, the intelligent security gate realizes the comprehensive, fast and accurate detection of illegal items carried by candidates through special technical means such as metal detection technology, imaging technology and intelligent identification system, which provides an important guarantee for the safety management of the college entrance examination room. The scientific and efficient working principle of the examination has made an important contribution to maintaining the fairness, impartiality and security of the examination. Therefore, in the future management of the college entrance examination room, the use of intelligent security doors should be further promoted, and its detection capabilities should be continuously improved and improved to ensure the smooth progress of the college entrance examination and the safety of the examination room.
