Abstract
The utility model discloses a new magnetic and infrared combined currency detector used for detecting genuine money from fake money, comprising an infrared detecting module, a magnetic detecting module and a central signal disposing cell. The magnetic detecting module is provided with a magnetic sensor. The central signal disposing cell receives the detecting signals of the two detecting modules, and does corresponding identity disposing to the detecting signals. The infrared detecting module consists of an infrared detecting element, a signal magnifying circuit and a signal shaping circuit; wherein, the infrared detecting element sends and receives the reflected infrared signal which is magnified by the magnifying circuit and is transmitted to the central signal disposing cell after being shaped by the shaping circuit. The utility model integrates functions of the magnetic and the infrared anti-fake detecting, so that the identity to currency and other marketable securities can be completed once, which not only fills a cap in the prior art, but also adapts the development of the anti-fraud technique, with advantage of easy use.
Description
Technical field
The utility model relates to a kind of money identifier, particularly a kind of money identifier that has magnetic, infrared compound identification function concurrently.
Background technology
In order to improve the false proof level of banknote and other securities, people have carried out integrated application to the anti-counterfeiting characteristic on these carriers in recent years, realize integrated anti-counterfeit, forge difficulty to increase.As dollar, Euro just contain magnetic anti-counterfeit feature and infrared pairing anti-counterfeiting characteristic simultaneously, on dollar, its front portrait adopts magnetic ink printing, infrared pairing ink printing is adopted at its back side, and Euro on, its number adopts magnetic ink printing, and infrared pairing ink printing is then adopted in its front.The banknote and the securities that have magnetic and infrared pairing feature roughly the same the time for this by its magnetic of simultaneous verification and infrared pairing double anti-forge feature, can differentiate that it is true and false.But owing to generally adopted magnetic characteristic false proof in the past, therefore existing magnetism detector is more, and infrared identifier is less, and particularly the identifier that can differentiate infrared pairing feature and have the magnetic identification function concurrently by signal identification just still less.
The utility model content
At the blank that prior art exists, the purpose of this utility model provides a kind of novel magnetic, Ultra-Red Compound Fake-Money Identifying Identifier.
For achieving the above object, this novel magnetic, Ultra-Red Compound Fake-Money Identifying Identifier comprise infrared detection module, magnetic detection module, central signal processing unit, have magnetic sensor in the magnetic detection module, the central signal processing unit receives the detection signal of above-mentioned two detection modules input, and detection signal is differentiated processing accordingly; Described infrared detection module is made of infrared detector cell, signal amplification circuit, signal transformation circuit, wherein the infrared signal of reflected back is launched and received to infrared detector cell, this signal is amplified by amplifying circuit, and is transferred to described central signal processing unit after the shaping circuit shaping.
Further, sensor in the described magnetic detection module is made of iron core, field coil and magnetic test coil, two groups of magnetic test coil symmetries are wrapped on the iron core of field coil both sides, to guarantee that under the situation of no extraneous magnetic signal induced electromotive force equal and opposite in direction, the direction of the output of two magnetic test coils are opposite.
Further, described infrared detection modular circuit is installed in one and has in the housing of infrared fileter, and wherein the position of the infrared fileter on the position of infrared detector cell and the housing is corresponding.
This novel magnetic, Ultra-Red Compound Fake-Money Identifying Identifier have magnetic concurrently and infrared two kinds of anti-counterfeiting characteristics detect identification function, make the real and fake discrimination of banknote and other securities is once finished, not only fill up the blank of prior art, adapted to the development of anti-counterfeiting technology, and easy to use.

Embodiment
As shown in Figure 1, the utility model is made of central signal processing unit, magnetic detection module infrared detection module, wherein the infrared detection module as shown in Figure 2, comprise housing 1 and be contained in the testing circuit that constitutes by infrared detector cell 3, amplifying circuit 4, shaping circuit 5 in the housing 1, the corresponding infrared detector cell of housing 1 front end 3 places are provided with infrared fileter 2, and the central signal processing unit carries out the real and fake discrimination processing to the signal of two detection modules input.The magnetic detection module as shown in Figure 3, constitute by mountain shaped iron core and coil, field coil L is wrapped on the intermediolateral column, two groups of magnetic test coil symmetries are wrapped on the two side columns, do not having under the situation of extraneous magnetic signal, the induced electromotive force direction of two magnetic test coil output terminals is opposite, size is identical, i.e. E=0.Fig. 4 is that figure line shown in the A is represented the infrared transmission feature among the figure by the infrared external reflection collection of illustrative plates of the infrared absorption of the banknote of infrared pairing ink printing and transmission feature, and figure line is represented characteristic infrared absorption shown in the B.As can be seen, at visible region, infrared absorption overlaps substantially with the characteristic curve of infrared transmission from this collection of illustrative plates, differs greatly in both curve reflected values of region of ultra-red.
Fig. 5 detects schematic diagram for infrared module, square frame part 6 is infrared absorption pattern region (concrete pattern is not shown), blank parts 7 between frame and the frame is infrared transmission pattern region (concrete pattern is not shown), as shown in FIG., the infrared transmission zone is different with the reflected light signal Final 8 degree in infrared absorption zone, infrared detector cell 3 sends corresponding signal 9 according to the distribution situation of infrared absorption on the banknote and infrared transmission pattern, this signal is processed into square-wave signal 10 back outputs, the detection signal 10 that the central signal processing unit is sent the infrared detection module here compares with standard signal, to judge the true and false of tested banknote.
During the utility model work, when the sensor on the close magnetic detection module of the banknote that has magnetic signal, difference appears in the induced electromotive force of two magnetic test coils on the sensor, and this difference is sent to the central signal processing unit and carries out the real and fake discrimination processing.And the infrared detection device on the infrared detection module detects the infrared absorption and the transmission feature of the coding pattern that become by infrared absorption China ink, infrared transmission ink print on the banknote, and detected signal amplified and after shaping handles, equally signal is sent to the central signal processing unit and carries out real and fake discrimination and handle.Last central signal processing unit sends control signal corresponding according to the real and fake discrimination result.
The utility model both can be used for detecting the banknote that only has anti-false signal of infrared pairing or magnetic anti-counterfeit signal, also can be used to detect the banknote that has infrared pairing and magnetic double anti-forge signal.
