Description
Technical field
The present invention relates to the member system systems for referring to hand vein recognition, belong to third generation technical field of biometric identification.
Background technique
Member card management system is the meeting for the exploitation of the industry situations such as chain special counter, brand shop, store, consumer entertainment place
Member's comprehensive management platform develops member system based on member card marketing mode, and multi-functional member card function can help to look forward to
Industry expands the consumer group, and cash register member card management, is integrated, supplemented with money, member's analysis integrated management, is disappeared by system to member
Take the analysis of data, the data informations such as the high product of loyalty and the high member of the level of consumption, sales volume is obtained, so as to administrative staff
Dynamic and market strategy is scientifically adjusted, promotes the enhancing of corporate member's loyalty, product category optimization, increases corporate sales volume
And profit.Member card management system is to corporate member's basic document, consumption, integral, Stored Value, promotion and preferential policy through letter
Breath management, reaches businessman and client and keeps good connection at any time, to allow client's Double Spending, improves customer loyalty, real
The purpose that existing achievement increases.Member card management system also has other than membership promotion abundant and member card management function
Member's all-purpose card function provides a variety of member card functions, and such as member card consumption, member card is supplemented with money, member card gives a discount, member card
Integral, the modification of member card accumulated point exchanging, member card rebating, member's clip pin, the management of member card account, member card transfer accounts, member card
It the functions such as checks account, really embodies the one card for multiple uses of member's card software, the characteristics of all-purpose card is used.Meanwhile enterprise can pass through meeting
Member's card system carries out comprehensive management to member, enterprise can understand at any time shops, member, member card consumption, side
It helps enterprise to mitigate terminal management difficulty, effectively carries out member system marketing.
In the prior art, most of using card managing, it is more advanced to be verified using biotechnology
Management, and refer to hand vein recognition biotechnology and just developed in this field.When with referring to that vein carries out authentication, acquisition refers to
The characteristics of image of vein, feature existing for ability when referring to living body.Within the system, the finger of non-living body is to cannot get vein image
Feature, thus can not identify, to also can not just fake.When with referring to that vein carries out authentication, acquisition is finger interior
Vein image feature, rather than the characteristics of image of finger surface.Thus, there is no any damages due to finger surface, mill
Damage, the dry or brings cognitive disorders such as overly wet.With referring to that vein carries out authentication, when acquisition finger venous image, finger without
It must contact with equipment, gently one put, identification can be completed.Antihygienic problem when this mode does not have a hand contact arrangement and
Fingertip surface features may be replicated brought safety problem, and avoid the Psychological inadaptability for being taken as and examining object, simultaneously
It will not be because that can not be identified after dirt contamination.Finger vena mode since vein is located at finger interior, the external factor such as temperature
Influence degree can be ignored, and be suitable for almost all users.User's acceptance is good.In addition to without occurring with scanner surface
Other than directly contacting, the scanning process of this Noninvasive not only it is simple again naturally, alleviate user due to worry sanitation degree or
Using trouble and resisting psychology that may be present.Because having the vivo identification of front, internal feature and contactless 3 aspects
Feature, it is ensured that the finger vein pattern of user is difficult to be forged.So refer to that vein recognition system security level is high, it is especially suitable
It is used together in the high place of safety requirements.Compared with prior art the advantages of: (1) belonging to interior physiological characteristic, will not wear, it is more difficult to pseudo-
It makes, there is very high security.(2) blood vessel feature usually becomes apparent from, recognizable, and anti-interference is good.(3) it can be achieved contactless
Measurement, wholesomeness is good, is easy to as user's receiving.(4) the not influence vulnerable to watch face scar or greasy dirt.It is lacked existing for the above technology
Point is: acquisition equipment has particular/special requirement, designs relative complex, manufacturing cost height.
Summary of the invention
The purpose of the present invention.
The present invention is exactly the difference for employee and visitor, and employee's use is allowed to refer to vein, and visitor is checked card using identity card, and
The member system system of the finger hand vein recognition of proposition.
The technical solution adopted in the present invention.
Refer to the member system system of hand vein recognition, including power supply, power driving circuit, refers to venous collection circuit, SD card, SD card
Interface circuit, cortexA8 or more arm processor, LCD display circuit, LCD display, audio output circuit, loudspeaker, RS232/
485 communication conversion circuits, access controller, power supply are connected by power driving circuit with the above arm processor of cortex A8,
Refer to that venous collection circuit is connected with cortexA8 or more arm processor, SD card passes through SD card interface circuit and cortexA8 or more
Arm processor is connected, and intercommunication visual information is transferred to LCD by LCD display circuit and shown by cortexA8 or more arm processor
Screen is spread out of audio prompt by loudspeaker by audio output circuit, and the above arm processor of cortex A8 is to finger hand vein recognition
Logic communication between circuit is controlled, and the above arm processor of cortex A8 configures near infrared light led camera, to firmly
Family and carry out refer to vein image extract and digitized processing, middle finger hand vein recognition follow the steps below:
The first step, training and projection refer to vein image, obtain five candidate finger vein images by the matching of classifier, training
Obtained optimized image feature；
Five candidates in second step, classifier, which refer to, finds best test image in vein image；
Third step is determined verifying criterion by matching key point number, and the setting maximum finger vein descriptor of match point number is
Most possible item obtains target and refers to vein image by characteristic matching.
Preferably, the power module: the DC power supply of 12V is provided for access controller circuit system；Ethernet connects
Mouthful: it is responsible for the information transmission of remote network control, while provides downstream interface for intelligent domestic gateway；Voice module: according to finger
Hand vein recognition result and access control information, to disengaging, personnel issue voice reminder information；Push-button interface: open the door request and enabling
The push-botton operation of confirmation sends low and high level signal by I/O interface.
Preferably, the voicefrequency circuit mainly includes that audio outputs and inputs processing circuit.Due to audio output signal
It is the analog signal that voltage is more than ten millivolts, thus power amplifier need to be first passed through and carry out gain adjustment, and A/D conversion circuit is turned
Digital audio and video signals after changing are transmitted to control chip.
Preferably, the voltage of cortexA8 or more arm processor obtains 5V by power supply adaptor transformation, and by 5V voltage
It is divided and is obtained by low difference voltage regulator AS1117AR-3.3V, and its voltage is carried out by steady pressure treatment by capacitor, thus
Guarantee to provide stable 3.3V voltage for each component and interface and provides 1.8V and 2.5V voltage for camera module.
