摘要:指纹识别系统是基于指纹识别的汽车启动系统的核心部分,它性能的优劣直接关系着汽
车防盗系统效果。本文针对汽车防盗问题设计开发了一款基于指纹识别的汽车启动系统,中央处
理模块采用 TMS320C5402 DSP,指纹采集传感器采用 MBF200传感器。该系统具有能耗低、抗
干扰能力强、可靠性高等优点,能够满足相关国家法规要求,基于指纹识别的汽车启动系统适用
于各类型汽车。

Abstract:Thefingerprintidentificationsystem thevehicleofcorepart start is based on fingerprint
identification,theperformance ofwhich has a directeffect on thevehicle anti— thispaper a
vehicle systemstart based on fingerprintidentification designed is forthe problemof vehicle anti-theft,the
TM S320C5402 DSP is used as the central processing module,the MBF200 sensor is used as fingerprint
acquisition vehicle systemstart based on fingerprint identification haslow energy consumption,
strong anti—interference and high reliability and can meet the relevant national regulations,therefore,the
vehiclesystem start based on fingerprint identificationapplied istypes to allofvehicles.
