Background analysis:

Nowadays, people are under great pressure in work and life. In their free time, going to the seaside to get close to nature and relax is a popular way of spending leisure time. Tourists often forget or discard some metal bottles, cans and other waste products. Over time, they will be buried in the shallow layer on the beach. When the sea water washes, they are exposed again, which can easily cause safety hazards such as the tourists get scratch. Nowadays, a metal foreign object detector for beaches with the characteristics of wide detection scope, accurate positioning, strong resolution, and easy operation has emerged.

 Functions:

Guochuang beach metal foreign object detector is used to detect and scan the beach, find magnetic abnormal signals, and automatically send out audible and visual alarm to indicate that there may be ferromagnetic foreign objects buried underneath.

 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 beach metal foreign object detector is mainly composed of key core equipment of micro-magnetic basic sensor array, which can be manufactured into handheld and cart types.
