基于生物特征汽车防盗系统的设计

Design of automobile anti-theft system based on the biological characteristics

依托指纹识别技术,以TMS320VC5402为核心,设计了基于生物特征的汽车防盗监控系统。该防盗监控系统包括指纹采集、报警系统、门控电路、驱动电路、通讯电路等组成。通过MBF200指纹传感器采集到指纹信号,并把信号送到DSP中央处理器进行指纹判别,根据识别的结果对汽车发动机进行控制,并及时以短信形式给用户发送报警信息。实践结果证明,该汽车防盗系统性能稳定可靠、实用性强,能有效提高汽车防盗报警系统的可靠性。

Based on the fingerprint identification technology, taking TSM320VC5402 as the core, based on biological characteristics of car anti-theft monitoring system, the monitoring system includes a fingerprint acquisition, alarm system, a gating circuit, drive circuit, communi- cation circuit. Through the MBF20Ofingerprint sensors to the fingerprint signal, and sends signals to the central processor DSP fingerprint, depending on the result of the identification of automotive engine control, and timely to the form of text messages to the user to send alarm information. The practice results show that, the automobile anti-theft system is stable and reliable performance, strong practicability, can ef- fectively improve the automobile anti-theft alarm system reliability.
