What metals does the security gate detect?In today's society,airports have become international traffic arteries.According to the statistics of security checkpoints,the number of people who try to pass through the customs with expired certificates or sets of certificates is hundreds of people every year.The traditional low-efficiency manual security check methods can no longer meet the needs of large international airports.Then,how to apply the existing high-tech technology to the airport system and make it a safe,stable and efficient detection technology is an urgent problem for airport security.As a special field,the airport is a field of"zero tolerance"for safety.Domestic high-tech enterprises have developed a high-definition face certificate comparison system through in-depth research and understanding of the needs of airports to assist manual inspections at airports.While passengers are conducting normal security checks,the domestic high-tech enterprise certificate-in-one automatic verification system is also working simultaneously.When suspicious information is found to be inconsistent with the personal certificates,the system will automatically prompt the security inspectors to strengthen manual verification.The core of the high-definition face ID comparison system is to compare ID cards and portraits.The system can extract the information in the ID card and compare it with the image of the ID card holder captured on the spot,and quickly identify whether the ID card is consistent with the user of the ID card.The recognition rate reaches more than 98%,which is faster and more accurate than the naked eye.The face images collected by the face recognition system can be recorded as very important monitoring data,stored in the monitoring database,used as an index for subsequent retrieval,or connected to the database of the public security and security departments for evidence collection and identification.In the airport immigration security monitoring system,face recognition plays multiple functions.On the one hand,it is to verify and detect the identity information of entry-exit personnel,and on the other hand,it is to control and manage the flow of people at the airport.Of course,it is important not to give suspicious personnel the opportunity to escape or enter the country.In important areas such as airports,customs,ports,and border inspections,accurate identification and information identification of large-scale groups of people is an important means of ensuring social public safety.It is of great significance in the fields of public security,justice,and commerce.Help play the powerful role of the public security investigation system,and realize the true sense of"requiring police force from science and technology".

　　Metal security door safety performance

　　The power supply of the whole machine is placed on the top of the host,and the power supply of the whole machine can be controlled by the remote control.It adopts an uninterruptible power supply protection system,and the battery power supply is not less than 8 hours.The system has parameter protection function when the power is off.It uses imported waterproof synthetic fiber materials.Manufactured and synthesized by precision processing technology,the LCD can be installed obliquely according to the characteristics of the human body's viewing angle,which is convenient for reading/operation.

　　Metal detection function

　　Metal detection security doors must have high security requirements,which include the following factors:

　　1.The uniformity of the magnetic field is the key to the detection rate;

　　2.The detection power of the security check must be sufficient to detect any dangerous metal objects,regardless of its entry position and angle;

　　3.The detection power of the metal detection security gate must be sufficient to detect people,no matter what speed they pass through;

　　4.It also needs to have the ability to detect ferrous metals and non-ferrous metals.

　　Detection area of metal security gate

　　According to the basic structure of the human body,it is divided into 12 overlapping mesh detection areas.Interactive transmission and reception to accurately determine the position of metal objects.Eliminate weak and blind areas in the detection area,with higher sensitivity and more stable performance.Double-sided infrared scanning can quickly capture the induction signal,eliminate the detection error caused by the induction lag when the human body passes,and automatically count the number of people passing through.The 12 main detection areas have a 1000-level sensitivity program,which can pre-set the possible parts,volume,weight,and size of metal objects according to the actual use conditions for proper sensitivity adjustment.
