Abstract

The invention provides an implicit magnetic code detection device. The implicit magnetic code detection device comprises a magnetic sensor, an amplifying circuit connected with the magnetic sensor, a shaping circuit connected with the amplifying circuit, and an A / D conversion circuit connected with the shaping circuit, and further comprises a single-chip microcomputer, a display unit connected with the single-chip microcomputer, and a data center, wherein the single-chip microcomputer is connected with the output terminal of the A / D conversion circuit. The implicit magnetic code detection device is low in cost, small in size, and convenient to carry; meanwhile, time for detection is short, and detection is accurate. By the introduction of the data center, large-scale management of data storage, calling and updating are more convenient. The invention further provides an implicit magnetic code detection method, wherein the magnetic sensor is used for picking up a signal, the signal is amplified, shaped and subjected to A / D conversion through the amplifying circuit, the shaping circuit and the A / D conversion circuit respectively, and the signal is transmitted to the single-chip microcomputer; the single-chip microcomputer and the data center are matched with each other for analyzing and identifying the signal, and an identification result is displayed. The implicit magnetic code detection method is simple, high in accuracy, and good in stability.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting, in particular to a hidden magnetic code detection device and detection method. Background technique [0002] Magnetic ink printing anti-counterfeiting technology is applied to commodity anti-counterfeiting. It has the advantages of high anti-counterfeiting strength, not easy to be imitated, convenient magnetic code printing, and low cost of anti-counterfeiting magnetic code. At present, the hidden magnetic code technology has not been applied in other aspects except that it is applied in the holographic security thread of multi-national currencies. The detection of currency mainly adopts special equipment to read and banknote detector inspection. The price of special equipment is hundreds of thousands of yuan, and the bank's internal staff will identify the holographic security line through specialized technology. The banknote detector only uses simple graphic comparison to identify the face ...
