摘要
针对目前市面上指纹识别的汽车车锁少,且均是固定在汽车本身,没有可以遥控使用的指纹识别车锁系统的问题。文中设计了基于指纹识别的蓝牙车锁系统,其通过单片机将蓝牙模块与指纹识别模块相结合,让指纹识别系统可以随身携带,远距离使用,提高了系统的便利性。此外,系统采用了指纹解锁方式,相比传统解锁方式更加可靠,同时还可以保证钥匙丢失或被盗后的车锁不会被他人打开,安全性能大幅增强。经过实验测试,文中设计的基于指纹识别的蓝牙车锁系统能够远程指纹识别开启车门,其在5 m内的开锁正确率高达97%。
In view of the fact that the fingerprint lock on the market is less and is fixed in the ear itself and there is no problem that the fingerprint recognition system can be used for remote control, a Bluetooth lock system based on fingerprint reeognitionis proposed in this paper. This system combines Bluetooth module and fingerprint identification module through single chip microcomputer, so that fingerprint identification system can be carried around and used remotely, which improves the convenience of the system.In addition, the system uses a fingerprint unlock mode, compared to the traditional way of unlocking more reliable, but also to ensure that the keys lost or stolen after the ear locks will not be opened by others, security performance greatly enhanced.Through experimental tests, the Bluetooth based vehicle lock system designed by this paper can open the door for remote fingerprint identification, and the correct rate of unlocking in 5m is as high as 97%.
