Abstract

The utility model discloses a hawk-eye bill identifier, which comprises a light source system, a control circuit, a driving circuit, an image collector and a display. The light source system includes a group of light source transmitters, the control circuit is used for switching light sources, the image collector collects bill images after stimulation with the light sources, and the bill images are transmitted onto the display through a photoelectric sensor. By the aid of the design of two novel side bill outlets, when bills are endorsed over for a plurality of times, bill allonges are too long, the detected bills can be taken out of outlets at two ends, and folding and bending are omitted in detection so that the bills are kept even. By the aid of the design of three groups of image collection units, a plurality of spectroscopic light sources from ultraviolet to infrared are arranged, various main anti-counterfeiting features such as paper, printing, ink and the like of identified currencies and bills can be identified under seven different light sources, and full-width images, local images and detail images of the anti-counterfeiting features of the currencies and bills can be collected respectively. The hawk-eye bill identifier is provided with a USB (universal serial bus) digital video output interface and an AV (audio-video) analog signal output interface, and can be externally connected with the display to check the anti-counterfeiting features of the detected currencies and bills.

Description

Hawkeye bill identifier

Technical field

The utility model relates to a kind of hawkeye bill identifier, is specifically designed to the truth identification and the discriminating of various countries' currency, various bills, and is applied widely, simple to operate, differentiate fast.The utility model adopts the ccd image collecting unit, can under seven kinds of Different Light such as white light, white sidelight, ultraviolet light, infrared light, infrared sidelight, back of the body printing opacity and combined light source, discern certified various countries currency, multiple main anti-counterfeiting characteristics such as the paper of various bills etc., printing, printing ink.

Background technology

At present, the existing currency in market, bill recognition device are based on all that some limited technological means realize, they all are to utilize magnetic signal, ultraviolet, infrared, IR scanning etc. relatively to have the detection means of characteristics to finish identification basically.False proof device mainly is simply to be formed by connecting by single battery, resistance, ultraviolet lamp tube, magnifier.Its anti-counterfeiting technology is single, can't satisfy the requirement of accurate identification or evaluation variety classes bill, has great drawback and hidden danger.And various countries' currency pattern of selecting for use in the existing software and hardware system of identification both at home and abroad, mostly be the picture of online download, and be not data message from real banknote sample, bill sample, thereby the false proof data message that usually causes is not accurate enough full and accurate, information is lost easily, in the process of identification, deform with smudgy the accuracy of influence identification unavoidably.

Summary of the invention

The technical scheme that its technical matters that solves the utility model adopts is:

Adopt the positioning shooting head, with the Different Light annular as for around the camera, after making the user press the light source change-over switch, luminance by surface-mounted integrated circuit control light source shows white light, white sidelight, ultraviolet light, infrared light, infrared sidelight, back of the body printing opacity and combined light source in turn, to excite its corresponding orientative feature on the bill of irradiate light to the operating surface, camera is taken in display effect and is amplified, and shows on liquid crystal display after by circuit board image being changed into simulating signal.Adopt closed design, reduce external environment light the influence in currency, the papers qualification process.

Its major technique feature is:

(1) control circuit is responsible for the conversion of various light sources;

(2) driving circuit is responsible for display image on display;

(3) image acquisition device comprises three groups of image harvesters;

(4) image display can be connected on the computing machine, by software control can realize with database in image compare.

(3) concrete function

A, the port function of drawing a bill: in equipment both sides designs ticket outlet is arranged, when bill through repeatedly negotiability, when the bill allonge is long, can take out detected bill from the outlet at two ends, need not fold during detection, bending, keep the smooth of bill;

The special-purpose paper papery of b, former factory measuring ability: 60 times of enlarged images that provide by trickle video camera are also selected multiple light source, can clear observation paper pulp fiber thickness, density, stick together etc.;

C, filament measuring ability: 60 times of enlarged images that provide by trickle video camera also switch various light sources, can the filametntary thickness of clear observation, move towards, degree of sticking together and fluorescent color;

D, to the fluorescence logo measuring ability of currency, bill: 30 times of enlarged images that provide by local video camera also switch various light sources, can observe the fluorescent color pattern of coloured logo and colourless logo;

E, full width measuring ability: the 1 times of image that provides by the full width video camera also switches various light sources, can clearly observe the watermark layout of currency, bill full width face, characteristic infrared absorption, Ultraluminescence feature.

F, connect computer function: additional USB video interface, can directly connect computer, with needed video image transmit, preservation etc., the standard device of gathering as true and false currency, bill data.
