摘要
为将超声波指纹识别技术应用在汽车进入系统中,实现指纹识别汽车解锁,提出一种汽车智能进入系统。该系统由单片机、指纹模组及外围电路等组成。在基于超声波指纹识别系统框图的基础上,结合实际的指纹模组和MCU给出软件设计概要,使用Protel软件画出系统中部分外围模块的电路原理图。该系统在提高用户解锁汽车便捷性的同时,又提高了安全性能。
In order to apply the uhrasonic fingerprint identification technology to the vehicle entry system and realize the automobile unlocking, an intelligent vehicle entry system is proposed. The system is composed of MCU, fingerprint modules and peripheral circuits. Based on the block diagram of the uhrasonic fingerprint identification system, the software design outline is given combining with the actual fingerprint modules and MCU, and the circuit schematic diagram of some peripheral modules in the system is drawn by Protel software. The system improves the users＇ convenience while unlocking the vehicle, and improves the satety performance.
