Background analysis:

With decades of development, security monitoring system technology can be roughly divided into four stages: analog monitoring, digital monitoring, network monitoring and intelligent monitoring. As an emerging technology, magnetic imaging has also been widely used in the field of security, and has been gradually integrated with other technologies, delivering better security effects. The real-time online magnetic security inspection system developed on the basis of Guochuang Micro-magnetic Basic Sensor can conduct security inspection on people and objects, and detect whether they contains ferromagnetic objects. Compared with traditional magnetic security inspection system, the security inspection system has higher sensitivity, can detect smaller ferromagnetic objects, and realize the positioning of ferromagnetic objects through magnetic imaging technology. It is widely used in important areas such as airports, embassies, prisons, museums, banks, etc.

 Principle:

The magnetic anomaly target contains materials or currents with ferromagnetic characteristics (such as iron, cobalt, nickel, etc.), and the magnetic field strength is inversely proportional to the target distance cube, H∝M/R³. We use Guochuang Micro-magnetic Basic Sensor Array to detect the magnetic anomaly information caused by the ferromagnetic target, and determine the feature information of the ferromagnetic target according to the corresponding model algorithm.

 

 Technical solution:

Guochuang Magnetic Imaging System is mainly composed of multi-channel Guochuang Micro-magnetic Basic Sensor Array as the key core equipment, and real-time magnetic imaging is conducted on ferromagnetic foreign objects in the protected area on a real-time and all-day basis.

 

  

 The main components of the system:

1. The magnetic imaging security detection system is composed of micro-magnetic basic sensor array, communication module, digital signal unit, etc.;

2. The micro-magnetic basic sensor array is fixedly installed or portable in the equipment, conducts magnetic scanning and imaging of suspicious targets, real-time online monitoring and displays the shape of ferromagnetic objects (knife, gun, and other controlling facilitators) that may be carried, and sound and light alarms ；

3. Related algorithms include: micro-magnetic basic sensor array calibration, environmental noise suppression, processing of magnetic anomaly targets small signal, etc.;

4. Network data center: collection of data and information such as micro-magnetic basic sensor array data and magnetic anomaly early warning positioning signals;

5. Terminal console: display the working status and early warning information of the magnetic imaging security detection system.
