The invention provides a metal detecting positioning system which is used for detecting metal. The system comprises at least one metal identification signal receiving unit and a master controller. Themetal identification signal receiving unit comprises a first metal identification area and a second metal identification area which are surrounded by continuous winding coils. The master controller receives the signal of the metal identification signal receiving unit and compares the signal of the metal identification signal receiving unit with a reference signal, thereby generating a metal detecting signal and a metal positioning signal. The metal detecting positioning system and the method thereof are suitable for detection of metal foreign matters on the condition of existence of an external magnetic field. Compared with a traditional solution of performing metal detection by means of an electromagnetic signal of an electromagnetic transmitter, the metal detecting system according to the invention is not affected by the external magnetic field. In a fixed magnetic field environment or an alternate magnetic field environment with known or unknown field strength, whether metal existscan be identified.
Description
Technical field [0001] The invention relates to the technical field of object detection, in particular to metal detection, and is a metal detection positioning system, a metal detection method and a metal positioning method. Background technique [0002] Metal detectors are required in many fields such as security inspection, food processing, and textile production. [0003] In the prior art, the metal detector includes an electromagnetic transmitter. In the process of metal detection, the magnetic field generator generates a magnetic field and receives induction from the detection area to produce a metal detection identification signal. The accuracy and reliability of metal detection depend on the stability of the electromagnetic transmitter. This kind of detector is only suitable for metal detection in an environment without an external magnetic field, and in an area where a magnetic field exists, especially in a magnetic field environment with varying field strength, the exter...
