摘要

随着自动控制、计算机、通信、网络等技术的交叉发展，自动控制系统结构发生了重大变革。在这个背景下，采用ARM7架构的以ARM Cortex-M3[1]为内核的微控制器STM32F103，结合无线传输技术和生物识别技术中的指纹识别技术，通过FM-70指纹识别模块、薄膜矩阵键盘模块、12864OLED液晶显示模块以及STC89C52单片机[2]、继电器等模块设计了一款无线指纹密码控制系统。无线指纹密码控制系统分为2部分，STM32F103是控制端，STC89C52是被控制端，在STM32F103和STC89C52之间通过nRF24L01[3]无线收发芯片传递控制的命令，实现对所有设备开关的控制。适合应用在工业、医疗和家居，经过实验测试，系统具有安全可靠、操作简便、成本低等优点，因此具有很强的推广性和竞争力。

Abstract

With the development of automatic control, computer, communication, network and so on,

the structure of automatic control system has been changed greatly.In this context, the ARM7 architecture based on arm Cortex-M3[1] kernel STM32F103 Micro controller, combined with wireless transmission technology and biological recognition technology of fingerprint identification technology, through FM-70 fingerprint identification module, film matrix keyboard module, 12864OLED liquid crystal display module and STC89C52 microcontroller[2], relays, etc. module designed a wireless fingerprint password control system. Wireless fingerprint password control system is divided into 2 parts, STM32F103 is end control STC89C52 is the controlled end and between the STM32F103 and STC89C52 by nRF24L01[3] wireless transceiver chip to transmit control command, the implementation of all the devices switch control. It is suitable for application in industry, medical and household. After experiment, the system has the advantages of safe, reliable, simple operation and low cost, so it has strong promotion and competitiveness.
