Description
Technical field
The utility model relates to a kind of slide fingerprint automobile key.
Background technology
Along with the continuous increase of automobile demand, people also improve constantly convenience and the security requirement that automobile uses.At present existing fingerprint anti-theft technology is applied in automobile burglar, is so far the safest automobile burglar technology.Because the fingerprint anti-theft technology was used mainly to concentrate on and was adopted area formula fingerprint sensor early stage, and area formula fingerprint sensor volume is excessive relatively, cost is too high, power consumption is also higher, the installation site can only be fixed on body portion, focuses mostly at door handle or automobile ignition switch, and it gathers somatic data by fingerprint sensor, discern back and then Control of Automobile door lock or ignition system with fingerprint base, this makes revealing virtually in public of user fingerprints.Because the area co-volume is excessive relatively, and power consumption is higher, can't combine with remote-control key simultaneously, use inconvenience, the application aspect remote control suffers restraints always.Be the technology that realizes that fingerprint sensor and telecar key combine, denomination of invention is that " a kind of electron key that can discern fingerprint " (notice of authorization number is CN2580523, notice of authorization day is on October 15th, 2003) Chinese patent a kind of finger print remote control car key that finger-printer reader and infrared radio transmitter or RF radiofrequency launcher are combined is disclosed, (publication number is CN1796712A and denomination of invention is for " a kind of telecar door key of fingerprint control ", open day is on July 5th, 2006) Chinese patent a kind of finger print remote control car key that finger-printer reader and blue teeth wireless transmitter are combined is disclosed, other has denomination of invention is that " finger print remote control car key " (notice of authorization number is CN201037334, notice of authorization day is on March 19th, 2008) Chinese patent a kind of finger print remote control car key that has liquid crystal indicator is disclosed, but this three's fingerprint sensor can only read the superiors of skin surface, when foul is arranged on hand, during moist or old cutis laxa, the fingerprint sensor identification is slow even can not obtain normal lines information, cause the car owner not open door or do not start engine, and their volume is bigger, carries inconvenience.Moreover, because three's fingerprint sensor can only scan the superiors on somatic fingerprint surface, when car owner's fingerprint is stolen accidentally, the offender can use and forge the prosthetic finger have car owner's fingerprint surface or rubber finger etc. and get by under false pretences into the car, bring tremendous loss to the car owner, therefore the security performance and the functional performance of fingerprint remote control key of the prior art are still undesirable.
The utility model content
The utility model is exactly in order to address the above problem, and provides a kind of theftproof performance slide fingerprint automobile key good and easy to carry, to increase safety and the convenience that automobile uses.
The technical problem of the required solution of the utility model can be achieved through the following technical solutions:
A kind of slide fingerprint automobile key, comprise by power supply, fingerprint input validation part, central processing unit, the key main body that RF radio-frequency module and button connect to form, wherein said fingerprint input validation partly are provided with sweep fingerprint sensor, signal processing module, the subscriber information storing module that adopts the RF imaging technique; The sweep fingerprint sensor of described employing RF imaging technique is connected with signal processing module; Described signal processing module respectively with the joining of subscriber information storing module and central processing unit; Described central processing unit and RF radiofrequency emitting module join; Power circuit and fingerprint input validation part, central processing unit, RF radio-frequency module join so that working power to be provided.
Described sweep fingerprint sensor is with respect to traditional area formula fingerprint sensor, has resolution ratio height, volume is little, cost is low, effect is little advantage.Sweep fingerprint sensor adopts RF imaging technique scanning somatic fingerprint skin corium, carry out vivo identification, the variation that can avoid surperficial dead skin is as decortication, booty etc., also can prevent simultaneously by steal that fingerprint surface realizes stealing may, increased safety greatly.Fingerprint image be handled and be generated to signal processing module can with the information that collects in the short time at the utmost point for the signal processing module of the finger print information that adopts the DSP algorithm process and collect, reduces user's the time of waiting until.
Described central processing unit mainly comprises parts such as CPU, button input, battery, mainly is to handle at communication between each system and signal.
Described RF radio frequency part mainly contains two parts to be formed, and a part is the transmitter module of remote-control key end, and another part is the module of accepting of automobile end.The power that the RF radio-frequency module that is adopted needs is very little, and battery life is prolonged.
Concrete, fingerprint sensor described in the present invention, signal processing module, subscriber information storing module, central processing unit, RF radio-frequency module all adopt the known technology in the prior art field, relevant fingerprint sensor, signal processing module, subscriber information storing module.Central processing unit, RF radio-frequency module known solution in the prior art, those skilled in the art all knows, so no longer repeat at this.
Owing to adopted technique scheme, the utlity model has the low advantage that is convenient for carrying of the little effect of volume; And sweep fingerprint sensor is by adopting RF imaging technique scanning somatic fingerprint skin corium, can avoid because the skin surface wearing and tearing, injured, relatively drying or old cutis laxa cause to read fingerprint unreliable; Dwindling of fingerprint sensor volume also makes the manufacturing cost of the utility model slide fingerprint automobile key significantly be reduced simultaneously.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a system architecture theory diagram of the present utility model.
The specific embodiment
In order to make technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand, the utility model is further elaborated below in conjunction with embodiment.
