The system comprises a data acquisition system which is based on a low temperature polycrystalline silicon pressure sensor, a matching system which is based on a DSP non image array data processing, a mechatronics control system which is based on a msp 430 SCM, and a voltage stabilized multi-channel power supply system. The utility model uses the fingerprint eigenvalue to replace the current common fingerprint image when doing the fingerprint data acquisition, comparison, and identification; when compared and identified, the utility model has high reliability. The FRR is < 0.01%, the FAR is < 0.001%, and the accuracy can reach to 0.00000001. The system breaks through the identification technique of the past fingerprint image pattern, and has high self-adaptation; the system can also adapts to humidity, water, dryness, low temperature, dirt, lightness scratch wear, and the particularity of fingers of the aged and the children and are not influenced by these elements. The low temperature of the working environment and storage and the wide temperature limit can prevent the fingerprint image being copied or stolen.
Description
Technical field the utility model relates to a kind of fingerprint recognition control system, specifically a kind of dot matrix digit fingerprint recognition system.
Background technology fingerprint anti-theft door lock in the market all adopts the fingerprint image control system for identifying, though the security performance of its control system is greatly improved, but it also mainly exists following defective: 1, common fingerprint recognition system adopts optics or ordinary silicon crystal static capacitive fingerprint sensor mostly, can not be based on the recognition system that this class sensor is made in operation below 0 ℃, when being lower than-10 ℃, will lose storage data, sensor surface can stay fingerprint in the fingerprint collecting process simultaneously, duplicates fingerprint to the lawless person and brings hidden danger.2, bad adaptability, if user's finger is dry during operation, moist, temperature is lower or finger when dirt is arranged, the sensitivity of fingerprint recognition will be very poor, even can not accurately discern, and brings inconvenience to the user.3, existing fingerprint recognition system all adopts fingerprint image relatively to discern, this just requires fingerprint acquisition system must gather user's finger print image, and fingerprint image is stored in the storage chip, (generally comparison time was less than 1 second with comparison time to have prolonged the acquisition time of fingerprint so on the one hand, acquisition time was less than 2 seconds) (consciousness of this section seems that the time is very short, not too conform to the consciousness that prolongs), on the other hand fingerprint image be stored in the privacy of having invaded the user in some sense, even might be stolen image pattern research by external scientific research institution.
The summary of the invention technical problem to be solved in the utility model be to propose a kind of adopt non-fingerprint image compare identification, temperature limit is wide, adaptability is strong, the dot matrix digit fingerprint recognition control system that can avoid fingerprint image to be replicated or to steal.
For solving the problems of the technologies described above, the fingerprint comparison system that the utility model dot matrix digit fingerprint recognition control system comprises data acquisition system (DAS) based on the low temperature polycrystalline silicon pressure transducer, handle based on the non-image dot array data of DSP, based on electromechanical control system and four parts of voltage stabilizing multiple-way feed system of MSP430 single-chip microcomputer.
Owing to adopted above-mentioned technical pattern, during the work of the utility model dot matrix digit fingerprint recognition control system, its data acquisition system (DAS) is directly gathered fingerprint characteristic value by the dot matrix digit acquisition mode and (is mainly comprised fingerprint ridge orientation dot matrix digit parameter value, the fingerprint crossing point, cut off, bifurcation point, the remittance node, lines curvature, between points impedance behind the making alive, static distributes, line peak and line paddy electric pale pinkish purple, the comparison parameter value of the varicose power of distributed points around the varicose power of the fingerprint central distribution point under the certain pressure and the fingerprint, the humiture parameter value), it is not to form fingerprint image, integrate formation sample characteristics numerical value but directly extract the dot matrix digit value, store.During identification, also be to substitute fingerprint image commonly used at present with fingerprint characteristic value, the identification of comparing, good reliability is refused sincere＜0.01%; Accuracy of system identification＜0.001%; Degree of accuracy can reach 0.00000001.Simultaneously, because the utility model control system has broken through fingerprint image mode identification technology in the past on recognition technology, its adaptivity is strong, can adapt to humidity automatically, get wet, drying, low temperature, dirt, slightly scratch the singularity of wearing and tearing, old man, child's finger and be not subjected to the influence of these factors, working temperature environment is at-20 ℃---between 60 ℃, storing temperature is at-30 ℃---between 80 ℃, temperature limit is wide, and be not subjected to the influence of air humidity and pollution, avoided fingerprint image to be replicated or to steal simultaneously yet.
Description of drawings is described in further detail the utility model below in conjunction with drawings and embodiments.
Fig. 1 is the structure and the fundamental diagram of dot matrix digit fingerprint recognition control system.
Embodiment as shown in the figure, the II of fingerprint comparison system that dot matrix digit fingerprint recognition control system comprises data acquisition system (DAS) I based on the low temperature polycrystalline silicon pressure transducer, handle based on the non-image dot array data of DSP, based on electromechanical control system III and four parts of voltage stabilizing multiple-way feed system IV of MSP4 30 single-chip microcomputers.Data acquisition system (DAS) I utilizes the character numerical value of pressure sensitivity low temperature polycrystalline silicon dot matrix digit sensor acquisition fingerprint, by the TMS320DSP data processor processes, forms best dot matrix numeral sample character numerical value, stores in storer.The II of fingerprint comparison system utilizes pressure sensitivity low temperature polycrystalline silicon dot matrix digit collector to gather the character numerical value of fingerprint, with the identification of comparing of the sample value in the data sample storehouse in the storer, exports corresponding instruction according to comparison result.Its comparison is identical with existing fingerprint recognition system with treatment scheme.Electromechanical control system III adopts the MSP430 single-chip microcomputer to realize as controller, mainly is to be used for the signal of fingerprint module output is amplified, and action, liquid crystal display, the information storage of control micromotor are with upper machine communication etc.This module is in order to cooperate fingerprint identification module, according to different application scenarios, realizes the peripheral function of system of fingerprints.Clock control system can realize the time according to the interim fingerprint storage of the self-defined deletion of user's demand.Voice system can be pointed out the user on off state based on the dot matrix digit fingerprint recognition system.The voltage stabilizing multiple-way feed system IV provide four kinds of power supply modes such as 220V alternating current, rechargeable battery, sun power and dry cell, and is versatile and flexible, is more convenient for powering with other power supply when a kind of power supply can not be powered at once.
In the utility model dot matrix digit fingerprint recognition control system anti-theft feature can be set, by the rapid notifying cell of phone security personnel, 110 or the particular telephone that is provided with of owner report to the police warning device in the priming chamber rapidly simultaneously.Also can control or check the opening of fingerprint recognition system by the internet.On the indoor panel of fingerprint recognition system, can be provided with safe escape button and outdoor login control knob.
