Dynamic detection mechanism and method for RMB magnetic ink

Abstract

The invention relates to an RMB magnetic printing ink dynamic detection mechanism and a detection method thereof. The detection mechanism is arranged between a paper money input mechanism and a paper money output mechanism of a money counter, and comprises a plurality of paper money pressing wheels inserted in a paper money pressing wheel shaft of the money counter, and a right contra-rotating wheel and a left contra-rotating wheel inserted in a contra-rotating wheel shaft of the money counter. A coded disc is arranged at one end of the paper money pressing wheel shaft; and a pair of coded disc geminate transistors is arranged on the coded dis. At least two pairs of penetration type infrared emission counting opto-couplers and penetration type infrared reception counting opto-couplers and at least three reluctance type magnetic heads are arranged between the paper money pressing wheel shaft and the contra-rotating wheel shaft. Magnetic head pressing wheels arranged corresponding to the reluctance type magnetic heads are arranged on the paper money pressing wheel shaft. The method comprises the following steps: magnetic signals of the reluctance type magnetic heads are controlled by a CPU chip and are amplified, filtered, corrected and compared; the magnetic signals are converted into digital signals through an A / D converter; and the digital signals are processed, calculated and judged so as to finally judge the truth of RMB.

Description

technical field [0001] The invention relates to detection equipment and a detection method for anti-counterfeit features of RMB, and relates to a dynamic detection mechanism and detection method of RMB magnetic ink. Background technique [0002] Everyone in the industry knows that the most advanced banknote anti-counterfeiting technology in the world is the Swiss franc. It can be said that the Swiss franc is the culmination of the world's advanced anti-counterfeiting technology. [0003] my country's fourth set of RMB borrowed from the anti-counterfeiting technology of the Swiss franc, and adopted more than ten anti-counterfeiting designs. One of them is the setting of magnetic ink in certain specific positions and areas of the RMB. [0004] And most of the existing banknote counting machines are finalized products, which do not possess the dynamic detection function to the above-mentioned magnetic ink at all. Contents of the invention [0005] The object of the present ...
