一种新型车载智能防盗控制系统设计

A New Intelligent Vehicle Security Control System

针对指纹的不变性和唯一性的特点,设计了一种基于指纹识别的新型车载智能防盗控制系统。该方案采用刮擦式活体指纹传感器MBF310采集指纹,并结合GSM无线通信TC35i模块实现远程报警。根据MBF310、Atmega128和DSP芯片TMS320VC5402的特性,设计了系统硬件核心电路和指纹采集电路,并给出了系统软件设计方案。实验结果表明,该方案对合法指纹的识别率达95%以上,对不合法指纹实现远程报警率高达99%,方案科学可行,性能稳定,能有效地提高汽车防盗系统的可靠性,具有较强的实用意义。

Employing the uniqueness and invariability of fingerprint,a new intelligent vehicle security control system was designed based on fingerprint recognition.The system adopts sensor named MBF310 to collect vital fingerprint in touching style,and wireless communication GSM TC35i to realize remote alarming.The key circuit software was designed based on the characteristics of MBF310,Atmega128 and TMS320VC5402.The experimental results indicate that the identification rate of valid fingerprints reaches above 95%,while the identification rate of invalid fingerprints is above 99%.The plan is scientific and feasible.It enhances the reliability of automobile security system with great prospective application.
