Application environment and principle of mobile security screening gate detection door

First of all, let me first understand what are the main application environments of mobile phone security screening gates. The editor will tell you that the mobile phone security screening gate equipment system is suitable for prisons, detention centers, public resource centers, enterprises, public security, examination centers, units, detoxification centers, R&D centers, commercial conference venues, large enterprises and other industries.

What are the special functions of mobile phone detection gates? Eddy current detection and electromagnetic induction principles integrate weak signal detection technology, precision filtering technology, and digital signal processing technology to identify the electromagnetic identity characteristics of metal objects and determine the contraband carried by the person being inspected. It can effectively eliminate the interference of watches, belt buckles, keys, cigarettes, lighters and other daily carry-on items and accurately identify whether you carry a mobile phone in any state such as standby, shutdown, power on, battery removal, SIM card removal, etc., and alarm items are classified and displayed;

What is the detection range of mobile phone detection gates: mobile phone detection mode (mobile phone, mobile hard drive, laptop computer, digital camera,)

Mobile phone detection door equipment parameters:

1. The detection unit and the analog board form a signal sorting and filtering unit to realize the collection and frequency selection amplification of specific weak analog signals.

2. The detection technology uses the principle of electromagnetic induction and eddy current effect, and adopts digital signal processing technology.

3. The signal sampling processing module (acquisition card) adopts the structure of “floating point operation microprocessor + FPGA field programmable gate array”. The main frequency of the microprocessor is >100MHz and Flash is >256KB; the FPGA field programmable gate array cooperates with the sampling chip for dual-channel signal sampling, and the sampling rate is >20MHz. Cooperate with the corresponding embedded software to realize the sampling processing function.

4. The detection unit is required to form a through-type detection system with anti-interference ability and can adapt to installation sites with large metal interference. For example: communication equipment detectors can be installed side by side with a distance of no more than 50cm.

5. Alarm mode: The inspection door panel is equipped with an alarm light, alarm bell and volume button. When the person being inspected carries a mobile phone, the alarm light lights up and the alarm bell rings. The volume button can adjust the volume of the alarm sound.

6. The system can intuitively display the specific location of alarm items through virtual portraits on the display screen; the system should be able to realize remote computer connection and realize dual-screen alarm monitoring mode of the door body and remote duty room computer (arranged according to the actual situation of the user).
