Electromagnetic sensor-based coin sorting and counterfeit detecting device and sorting and counterfeit detecting method thereof

Abstract

The invention discloses an electromagnetic sensor-based coin sorting and counterfeit detecting device which comprises an electromagnetic sensor, an exciting circuit, a detection circuit, an upper computer and a mechanical driving mechanism, wherein the electromagnetic sensor comprises an exciting coil and a detection coil; the exciting circuit is in circuit connection with the output end of the exciting coil; the detection circuit is in circuit connection with the output end of the detection coil; the upper computer is in circuit connection with output ends of the exciting circuit and the detection circuit; the exciting circuit and the detection circuit are used for detecting a mutual inductance value generated by detected coins; the mechanical driving mechanism is in circuit connection with the output end of the upper computer; the mechanical driving mechanism comprises a detection zone and a sorting zone; the detection zone penetrates through the part between the exciting coil and the detection coil; the sorting zone is provided with a plurality of outlets; and the outlets of the sorting zone are respectively connected to a plurality of external coil receiving points corresponding to different coins. According to the electromagnetic sensor-based coin sorting and counterfeit detecting device disclosed by the invention, the kinds and the authenticity of the coils are judged by detecting the mutual inductance value of the coins through the coils, and further the sorting and finishing work of the coins is finished. The electromagnetic sensor-based coin sorting and counterfeit detecting device has the advantages of quickness in counterfeit detection, accuracy in classification, convenience in implementation and the like.

Description

technical field [0001] The invention relates to a coin identification technology using electromagnetic sensor technology, in particular to a coin sorting and counterfeit identification device based on an electromagnetic sensor and a sorting and counterfeit identification method thereof. Background technique [0002] Coins are widely used in daily life and economic activities. Due to factors such as small face value, large quantity, and inconvenient carrying, the sorting and sorting of coins has always been a complicated and unavoidable problem. [0003] Especially in institutions such as banks, large supermarkets, and bus companies where coins are concentrated, manual sorting is time-consuming and labor-intensive, and it is increasingly difficult to adapt to the requirements of economic development. [0004] The device of the invention realizes sorting and sorting according to the electromagnetic characteristic parameters of the coins. The measured mutual inductance value ...
