Description
Technical field
The present invention relates to a kind of physiological characteristic field of identity authentication, are specifically for use in and refer to hand vein recognition terminal based on children
Children's finger is fixed and measuring mechanism.
Background technology
It is a kind of advanced physiological characteristic identity recognizing technology to refer to vein identification.But it is general to refer to hand vein recognition at present
All it is applied to adult's identification, to be applied to children's identification mainly there are several key technical problems：One, Er Tongcheng
Long speed, the recognizer based on key point and distance can not be used directly；Two, children's finger is relatively grown up small, and adult makes
The part for referring to hand vein recognition equipment placement finger is larger, and children's finger may move wherein or posture is incorrect causes
Correctly typing or identification it can not refer to venous information；Three, the thickness of children's finger is less than adult, refers to the light source that hand vein recognition uses
Exposure intensity and image processing section needs are accordingly corrected.
Children abduct that event is more rampant, and a large amount of children encounter the problem of being difficult to confirm identity after being saved in recent years；Together
Shi Youtong wander away after because that can not determine identity, it is difficult to it is also a urgent problem to be solved to contact its relatives.We research and develop
The system that vein carries out child's authentication is particularly related to based on physiological characteristic, it, which will be substantially reduced, gives children for change and return to relatives
Difficulty at one's side.
Therefore, based on existing finger vein recognition system is transformed, it is applied to children's identification field with important
Realistic meaning.
Invention content
The purpose of the present invention designs regarding to the issue above and provides the auxiliary body that a kind of children refer to hand vein recognition terminal
Design, the mechanism will be incorporated into it is original finger hand vein recognition terminal on, carry out finger be inserted into guiding, assisting child finger fix,
It measures finger length and reading is sent to main control chip or the auxiliary body of ARM.
Using the guide groove and sliding block of subsidiary elastomeric element, carry out fingertip location and fix and refer to long reading, mechanism utilizes finger
The identification method of vein improves the identification difficulty of child and identification accuracy；It is adopted using the finger vein for being exclusively used in children
Collect equipment, make the authentication procedures more accurate quick to children, verification process is convenient and efficient.Based on the children's identity for referring to vein
Identifying system equipment have advance, practicability, reliability, compatibility, economy, it is safe the features such as.
Innovation scheme is used by the present invention solves technical problem：
Children refer to auxiliary body's design of hand vein recognition terminal, it includes guide groove, elastomeric element, infrared light supply, refers to vein
The parts such as collector, upper plate, pedestal.Main feature according to children physiology design feature, devises one kind and is referred to for children
The auxiliary body of hand vein recognition can guide child's finger and be fixed with level, while can measure finger length in terms of
Calculate identification corrected parameter.
Operation principle
Children refer to hand vein recognition unit：The guide groove of children's finger positioning module and elastomeric element can be by the hands of children first
Finger is directed to suitable position, and front end elastomeric element can assist fixed finger and measure finger length and send the data to master
Control, infrared light supply are irradiated, and near infrared light shone through finger vein acquirer, and generation refers to vein image.
Advantage of the present invention and good effect：
1. extending the application range for referring to hand vein recognition, important information leakage can be prevented in a variety of contexts.It can be with
On the basis of existing finger vein identification device is not transformed substantially, relies only on installation children's finger positioning module and carry out a small amount of electricity
Correct the children's identity authentication means for just obtaining high reliability in road.
2. it increases children's finger positioning module and has modified algorithm, by measuring and calculating child age gain of parameter pair
Children refer to effective identification of vein, change in the past refer to hand vein recognition equipment due to finger is of different sizes, children's finger position and
Posture influences identification, child growth speed leads to problems such as recognizer inapplicable soon.
Description of the drawings
Attached drawing 1 is each component connection diagram that children refer to hand vein recognition terminal.
As shown in the figure, above-mentioned children refer to each unit link structure part of hand vein recognition terminal by following Arabic numerals into
Row represents：
In figure：1st, infrared light supply, 2, elastomeric element, 3, guide groove, 4, upper plate, 5, refer to vein acquirer, 6, pedestal.
With reference to example and Figure of description, the present invention is described in further detail.
Specific embodiment
According to shown in Fig. 1, children refer to auxiliary body's major part of vein identity recognition terminal by 1, infrared light supply, and 2, elasticity
Component, 3, guide groove, 4, upper plate, 5, refer to vein acquirer, 6, pedestal composition.
As shown in the figure, the auxiliary body that children refer to vein identity recognition terminal is connected by 2 elastomeric elements with 3 guide grooves, 3 guide grooves
