Description
Technical Field
The utility model belongs to the technical field of metal detectors, and particularly relates to a high-precision detection device.
Background
The metal detector is a high-performance metal detector specially designed for security protection. Electromagnetic induction utilizes the principle of electromagnetic induction, and a sensitive magnetic field changes by using a coil through which alternating current passes. This magnetic field can induce eddy currents inside the metal object. The eddy currents will generate a magnetic field, which in turn affects the original magnetic field, triggering the detection of the seeker, and the current flowing through the transmitting coil will generate an electromagnetic field just as the motor would generate the same electromagnetic field. The polarity of the magnetic field is straight in the plane of the coil position. Whenever the current changes direction, the polarity of the magnetic field changes accordingly. This means that assuming that the coil is parallel to the ground, the direction of the magnetic field will change continuously, falling straight on the ground for a while, rising straight on the ground for a while, as the direction of the subsurface magnetic field changes repeatedly, it will interact with any conductor strategy object encountered, resulting in a small magnetic field being generated by the strategy object itself. The magnetic field polarity of the strategy object is exactly opposite to the magnetic field polarity of the transmitting coil. Assuming that the direction of the magnetic field generated by the transmitting coil is vertically upward and downward, the magnetic field of the strategic object is vertically upward on the ground, and the receiving coil can completely shield the magnetic field generated by the transmitting coil. But it does not shield the magnetic field of the subsurface detection target. Thus, when the receiving coil is positioned over a strategic object that emits a magnetic field, a small current will appear on the coil. The current vibrates at the same frequency as the magnetic field of the strategic object. The receiving coil will spread the frequency and transmit it to the console of the metal detector, and the components on the console will then analyze the signal.
