Description
Technical field
The utility model relates to Smart Home field, particularly a kind of finger porta venarum access control system based on ARM.
Background technology
Along with improving constantly of people's living standard, people are brought into schedule for the demand of household safe.Domestic security system in protection house, can reduce in burglary and this kind of common criminal offence of house robbery and plays useful effect.Along with the variation of means of crime, traditional mechanical lock has certain defect.At present a lot of residential quarter is all equipped with the antitheft door of Magnetic Control downstairs, and by key-press input password, or door lock is opened in living things feature recognition (such as recognition of face, fingerprint recognition, the identification of palm type) etc.But these methods have certain limitation: such as password is easily forgotten or leaked; Recognition of face objective environment of then being taken pictures affects, and discrimination is lower; And fingerprint or palm type are easily forged.This all brings potential safety hazard to family life.
Along with the development of science and technology, gather the finger vein image under finger skin, and extraction is subject to extensive concern and attention to carry out identification as biological characteristic.With other as the biological identification technology such as fingerprint, palmmprint is compared, refer to that vein is difficult to copying and forging more, its requirement must be that live body refers to that vein is just effective, and requires lower for the surface cleanliness of finger.The accuracy of system identification of the finger vena of feature rich and refuse sincere also lower than other biological recognition technology, has higher security performance.
Summary of the invention
The utility model, for the defect of prior art, provides a kind of finger porta venarum access control system based on ARM.
In order to solve the problem, the utility model by the following technical solutions: based on the finger porta venarum access control system of ARM, comprise ARM microcontroller, refer to venous collection module, memory module, power module, key-press module, voice cue module, relay, electromagnetic lock; Described finger venous collection module exports the signal of collection and is sent to ARM microcontroller; Described power module is that whole system is powered, and memory module, key-press module, relay are also connected with ARM microcontroller respectively; Described relay receives the control signal of ARM microcontroller, controls the switch of electromagnetic lock; Described memory module is primarily of FLASH memory and SDRAM storer composition; Described key-press module is used for the setting of working state of system; Described voice cue module carries out voice message.
Principle of work of the present utility model is: refer to that venous collection inside modules infrared light supply is opened when the finger of collected people stretches into and refers in venous collection groove, and ARM microcontroller controls infrared camera and takes pictures to pickup area sampling; ARM microcontroller completes and refers to vein image process, compares, and controlled the switch of electromagnetic lock by relay according to matching result with the sample stored in memory module, and voice cue module provides corresponding voice message according to matching result simultaneously.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts and refers to that vein identification technology controls the switch of electromagnetic lock, adds the security of gate control system, substantially increases antitheft performance; And carrying out condition selecting by key-press module, house owner can store finger venous information and delete; And for user without the need to carrying magnetic card or remembeing password, easy to use.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Embodiment
Below in conjunction with Fig. 1 and embodiment, the utility model is further illustrated.
Accompanying drawing 1 is a kind of specific embodiment of the present utility model.In the present embodiment, one refers to that hand vein recognition automotive theft proof system comprises ARM microcontroller 1, refers to venous collection module 2, memory module 3, power module 4, key-press module 5, voice cue module 6, relay 7, electromagnetic lock 8; Described finger venous collection module 2, memory module 3, power module 4, key-press module 5, voice cue module 6, relay 7 is connected with described ARM microcontroller 1 respectively; Described power module 4 is powered for whole system, refer to that venous collection module 2 gathers the finger of collected people and is transferred to ARM microcontroller 1, ARM microcontroller 1 carries out image procossing, the sample stored with memory module 3 is again compared, and peripheral components is controlled, if by authentication, ARM microcontroller 1 controls the switch of electromagnetic lock 8 by relay 7, and at this moment voice cue module 6 sends the voice message of " authentication is passed through "; If refer to that veneous signal comparison cannot be passed through, the voice message that voice cue module 6 sends " authentication failure, please gathers again ", if continuous 3 authentication faileds, then needs wait just can proceed associative operation after 3 minutes.Described ARM microcontroller 1 adopts S3C2440 model; Described memory module is primarily of FLASH memory and SDRAM storer composition, and FLASH memory adopts AM29LV160DB chip, and SDRAM storer adopts HY57V561620 chip; Key-press module 5 can carry out condition selecting, as stored the finger venous information of designated person and delete, or by password, native system is removed controls.
Adopt such scheme, the utility model adopts and refers to that hand vein recognition controls the switch of electromagnetic lock, has the features such as contactless, vivo identification, security performance are high, easy to use.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
