What is the role and detection principle of mobile phone detection gates at the airport?

With the development of the country and the advancement of science and technology, our daily travel methods have become more diverse. At the airport, we will carry out a series of tasks such as security inspections. The purpose is to improve air defense security. This has several advantages. First, it can ensure the security of passenger transportation at the airport. responsibility.

So, the mobile phone detection door is also used as a life check at the airport. What is its detection principle?

The role of the mobile phone detection door: for physical examination operations, when passengers pass through the detection door, the staff will carry out detailed inspection according to the location of its alarm. If there is no detection door, there are two problems. The first is the issue of order. Through a door, passengers can be consciously lined up without having to organize and labor. Second, you can eradicate the indication of the alarm light, conduct a close inspection, find out the source of the alarm, and use it as a reference test.

What is the principle?

The system uses metal classification recognition detection technology and magnetic field transformation technology to obtain the three-dimensional material and shape information of the contraband, so as to separate the contraband and daily products. The system is mainly composed of detection door, oil gas detection device, excitation signal transmitting module, eddy current / electromagnetic signal sensor, signal processing control module, data processing module and remote monitoring system. The signal processing module and data processing module are placed in the top case of the detection door, and the excitation signal transmitting module and eddy current / electromagnetic signal sensors are installed in the door panels on both sides, as shown in Figure 1. This system amplifies and filters the weak signals received by each eddy current / electromagnetic sensor to eliminate interference from the complex electromagnetic environment outside. Then analyze the data and extract signal characteristic parameters from it. Because different objects (including mobile phones) have specific eddy current and electromagnetic identity information characteristics, expert systems and adaptive recognition technologies are introduced to determine whether pedestrians in the passage carry contraband or electronic products. The system's real-time running status, parameter query settings, detection results, historical data, etc. can be operated in the remote monitoring system.
