Description
Technical field
The utility model belongs to financial document false distinguishing recognition technology, specifically the preposition financial document false distinguishing recognition device of a kind of contact-type image sensor CIS.
Background technology
Contact-type image sensor CIS scanning theory is for to be irradiated to internal light source on object to be scanned by contact-type image sensor, sensor to reflected light sensitization after, change light signal into electric signal, gather image information, become digital data transmission to follow-up equipment through analog to digital conversion circuit again, thus the scanning process of completing.CIS scanning technique is generally used for checkout equipment, for example, for detection of the false distinguishing checkout equipment of the sheet such as banknote finance valuable bills.Along with scientific and technical progress, false making level is also improving constantly, and forges kind also in continuous increase.If financial document false distinguishing recognition device only adopts a certain authentication technique, want to differentiate that all counterfeits are unrealistic.For improving identification result, must adopt the shared pattern of multiple authentication technique, this relates to multiple fields such as machinery, electronics, optics, magnetic, also will take into account standard-required and market cost requirement simultaneously.The authentication technique that general financial document false distinguishing is identified in technical employing has light image discriminating, light characteristic differentiation, magnetic to differentiate and other authentication technique.CIS pipe is mainly used in light image authentication technique, and CIS light source comprises visible ray as ruddiness, green glow etc.; Also comprise invisible light as infrared light, ultraviolet light etc.
The financial document false distinguishing recognition device CIS pipe of prior art is rearmounted, and its shortcoming is: 1. in false distinguishing identifying, easily make mistakes; 2. the efficiency of false distinguishing identification is low, and speed is slow.
Therefore, invent a kind of false distinguishing recognition accuracy high, the fast preposition financial document false distinguishing recognition device of contact-type image sensor of false distinguishing recognition speed is very necessary.
Utility model content
The purpose of this utility model is: the accuracy rate that improves false distinguishing identification; Accelerate false distinguishing recognition speed, it flows into the field of circulation to prevent technique of composite-RMB bank note and pseudo-coinage, reduces property loss, safeguards the safe order in financial system money market.
The utility model object is achieved in that
The financial document false distinguishing recognition device that contact-type image sensor CIS is preposition, comprises CIS transmission structure and false-identifying device, and CIS transmission structure is arranged on the front of false distinguishing position; CIS transmission structure is managed by two or more CIS and a sense channel forms; Described CIS pipe comprises CIS light source and CIS sensor, leaves for the space of detecting and transmitting between CIS pipe; Described upper and lower CIS pipe is placed on different vertical line.
The light signal that described CIS sensor receives, comprises reflected light signal and optical signal transmissive; Described optical signal transmissive is sent by the transmitted light source being arranged on CIS pipe; Described reflected light signal and optical signal transmissive can gather in timesharing.
Described transmitted light source is arranged on in two CIS pipes, and another CIS pipe is arranged and receives in vertical direction transmission signal.
Technical problem to be solved in the utility model is, for protean counterfeit money on the market, provides a kind of false distinguishing recognition accuracy high, the cash inspecting machine that false distinguishing recognition speed is fast.
Main points of the present utility model are:
Two CIS pipes and front and back, false distinguishing position are exchanged, guaranteed to leave for the processing time of follow-up false distinguishing abundance.Two CIS pipes point stand in object to be measured both sides, can obtain its two surface information.
Two described CIS sensing stations stagger, and its reflection spot also can be different, so just avoid the error causing because of light transmission.In order to obtain more spectrum picture information, plural CIS pipe can be set, improve distinguishing ability.
Add transmission units simultaneously, make reflected light signal and optical signal transmissive timesharing carry out reception & disposal, for false distinguishing identification provides how effective information.
The utility model compared with domestic and international existing like product, its creativeness be following some:
1, two road CIS sensors detect and have improved correct resolution;
2, CIS pipe is exchanged with other front and back, false-identifying device position, and to ensure to leave for the processing time of follow-up false distinguishing abundance, the collaborative qualification of multiple discrimination method, reduces False Rate;
3, different CIS pipes allow to be misplaced up and down relieving, can effectively obtain two surface informations that do not interfere with each other impact, and image information collecting working stability carries out;
4, CIS pipe can carry out the transmission reception of reflected light and transmitted light simultaneously, obtains reflectance spectrum and transmitted spectrum, and extra transmission plot data can provide more detailed information for follow-up discriminating, improve distinguishing ability.
The utility model has the advantages that:
1, differentiate that accuracy rate is high;
2, discriminating speed is fast;
3, it flows into the field of circulation can effectively to prevent technique of composite-RMB bank note and pseudo-coinage, reduces property loss, safeguards the safe order in financial system money market.
