Description
Technical field
The present invention relates to a kind of use to refer to hand vein recognition personnel system scheme, belongs to third generation technical field of biometric identification.
Background technology
HRMS, by improving satisfaction, the loyalty of interior employee, so as to improve employee's contribution degree,
That is performance, manager is helped to reduce cost and accelerated growth by effectively organizing to create value chain profit.Human resources
Integrated management solution, will be nearly all related to human resources with the data of concentration from the angle of human resource management
Information（Including：Organizational planning, recruitment management, the on-job leaving office archives of occurrences in human life, employee's resume, labour contract, rewards and punishments management, do
Utility, Hosp Ins, transfer management, Training Management, performance management, attendance management, time rate wage, piece-rate wage, dormitory pipe
Reason, self-service, the leader's examination ＆ approval of employee etc.）Unified management is got up.
The responsibility that HRMS is unit is established, the system of foundation must first understand unique tissue edge of tissue
Leather, corporate culture, operations objective, organization design, job design, employee's composition, staff requirement etc., therefore human resource management
System can not transplant, and enterprise must be based on self demand, according to above-mentioned five factors, and amount body planning meets the people needed for oneself
Human resource management system.Therefore, not so-called standardization HR management system.Plan and meet people needed for oneself
Human resource management system, manpower resources supervisor and person in charge must form enough designed capacitys, to establish human resources
Management system.
In the prior art, it is 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 carrying out authentication with finger vein, acquisition refers to
The characteristics of image of vein, refer to feature existing for ability during live body.Within the system, the palm of non-living body is to cannot get vein image
Feature, thus None- identified, so as to also can not just fake.When carrying out authentication with finger vein, acquisition is inside palm
Vein image feature, rather than the characteristics of image of palm surface.Thus, there is no any damage due to palm surface, mill
Damage, the dry or cognitive disorders brought such as overly wet.Carries out authentication with vein is referred to, during acquisition finger venous image, palm without
It must contact with equipment, gently one put, you can complete identification.Antihygienic problem when this mode does not have a hand contact arrangement and
Palm surface feature may be replicated caused safety problem, and avoid the Psychological inadaptability for being taken as and examining object, simultaneously
Also will not be because of None- identified after dirt contamination.Finger vena mode because vein is located inside palm, the external factor such as temperature
Influence degree can be ignored, and be suitable for almost all users.User's acceptance is good.Except without occurring with scanner surface
Beyond 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 vivo identification, internal feature and contactless 3 aspects before having
Feature, it is ensured that the finger vein pattern of user is difficult to be forged.So refer to vein recognition system safe class height, it is especially suitable
Used together in the high place of safety requirements.But it there is problems in the prior art to be solved：(1) Nei Shenglite is belonged to
Sign, will not wear, it is more difficult to forge, have very high security.(2) blood vessel feature generally becomes apparent from, and is easily discernible, anti-interference
It is good.(3) non-contact measurement can be achieved, wholesomeness is good, is easy to receive for user.(4) it is not easy by watch face scar or greasy dirt
Influence.Above technology has the drawback that：Collecting device has particular/special requirement, and design is relative complex, and manufacturing cost is high.
The content of the invention

Audio prompt is spread out of by loudspeaker, cortex A8 above arm processors are to referring to the logic communication between hand vein recognition and circuit
Be controlled, the cortex A8 above arm processor configuration near infrared light led cameras, visitor carry out refer to vein image extraction and
Digitized processing, its middle finger hand vein recognition follow the steps below：
The first step, training and projection refer to vein image, and the finger vein image of five candidates is obtained by the matching of grader, train
Obtained optimized image feature；
Five candidates in second step, grader, which refer to, finds optimal test image in vein image；
3rd step, counted out by matching key to determine to verify criterion, the count out finger vein descriptor of maximum of setting matching is
Most possible item, by characteristic matching, obtain target and refer to vein image.
Preferably, described power module:12V dc source is provided for access controller circuit system；Ethernet connects
Mouthful:It is responsible for the information transfer of remote network control, while downstream interface is provided for intelligent domestic gateway；Voice module:According to finger
Hand vein recognition result and access control information, voice reminder information is sent to disengaging personnel；Push-button interface:Open the door and ask and open the door
The push-botton operation of confirmation, low and high level signal is sent by I/O interfaces.
Preferably, the voicefrequency circuit mainly includes input and the output processing circuit of audio.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-adjusted, and A/D change-over circuits is turned
Digital audio and video signals after changing are sent to control chip.
Preferably, the voltage of cortex A8 above arm processor obtains 5V by power supply adaptor transformation, and 5V is electric
Pressure is obtained by low difference voltage regulator AS1117AR-3.3V partial pressures, and its voltage is carried out into voltage stabilizing processing by electric capacity, from
And ensure to provide stable 3.3V voltages for each component and interface and provide 1.8V and 2.5V voltages for camera module.
1st, beneficial effects of the present invention：
By the present invention using referring to vein biometric identification technology, can accurately identify user identity, and reaction speed 2s it
It is interior, the more place of number is suitable for, improves the degree of accuracy and the efficiency for referring to hand vein recognition.
