1.Structure
The HD-II Mobile Detection System is based on electromagnetic induction theory. It consists of detecting door, signal excitation-emission module, electromagnetic signal sensor, analog signal processing module, digital signal processing module, analysis & judgment alarm module and remote control system.
The system's working principles and the signal line are shown in fig. 1. The system is installed with 20 electromagnetic signal sensors and 10 signal processing units, which help the system take samples at high speed and in real-time, extract the features of electromagnetic signals and then analyze and judge these features and give alarms.
The system's structure is shown in fig. 2. The analog signal processing module and the digital signal processing module are installed in the crate which is on the top of the detecting door. The signal excitation-emission module and the electromagnetic signal sensor are installed on the both sides of the door, each side of which is with 8 sensors.
The system magnifys and filters the weak signals to suppress the interference from the complex electromagnetic environment. These processed signals are analyzed with finite element analysis technology and the gradient survey technology. And then the system will extract the signal characteristic parameters from these processed data. Because different objects(including mobile phones) with specific electromagnetic identity characteristics, the system extracts and analyzes these characteristics to judge the detected person in the passageway with mobile or not.
The real-time operating state, the parameter querying & setting, the results of detection and the historical data can be operated in the remote control system.
