摘　　要：针对智能门锁使用距离较短、指纹解锁易被盗取和功耗较大等问题,文章设计了以网络为数据传输途径,双重半虚拟指纹验证和密码验证为开锁方式的智能门锁控制系统,门控芯片选择STM32F103C8T6、无线通信模块选择ESP8266、指纹识别模块选择ZN632,和以ULN2004L作为步进电机的驱动电路等,实现了拥有本地和远程两种方式控制的智能门锁控制系统。经过试验表明,该设计不仅使用成本低、易安装,还拥有较好的防盗系统。同时解决了现有智能门锁使用距离短和指纹开锁易损坏、易被窃取指纹和识别不灵敏等弊端。Aiming at the shortage of intelligent door lock,the problem of fingerprint unlocking which is easy to be stolen and consumes a lot of power,etc.This paper designs a smart door lock control system with network as the data transmission path,double semi-virtual fingerprint verification and password verification as unlocking mode.The gate chip selects STM32 F103 C8 T6,the wireless communication module selects ESP8266,the fingerprint identification module selects ZN632,and the ULN2004 L is used as the driving circuit of the stepping motor,etc.,realizing the intelligent door lock control system with local and remote control.Tests show that this design not only achieves the expected design effect,but also has a better anti-theft system,At the same time,it solves the shortcomings of the existing intelligent lock,such as using in a short distance and fingerprint opening,which are easily damaged,easy to be stolen and insensitive to fingerprint identification.
