基于wifi的智能指纹密码锁设计

ABSTRACTIn recent years,with the rapid development of social economy,information,security products in the security risk is more and more high,people's awareness of theprotection of personal privacy is also more and more strong,also with thedevelopment of networking technology,people on the safety and convenient securityproducts demand more and more urgent.The main content of this paper is to study thedesign of WiFi intelligent fingerprint password lock based on,is committed to byusing fingerprint identification technology and WiFi technology of fingerprintpassword control lock and control the phone lock implementation and design,so thataccess control system more secure,more convenient.Paper systematically describes the development of fingerprint identificationtechnology and WiFi communication are systematically elaborated in this thesis,thecombination of fingerprint identification technology and Microcontroller use WiFi,achieve the realization of mobile phone communication with the MCU technology,hardware design and software system.Through research and demonstration,thedesign and implementation of the WiFi communication technology and fingerprintidentification technology to control the door lock.Through continuous experiment,analysis,debugging and the design of the circuit of each sub module.Realize throughfpml0a fingerprint module to the fingerprint add,search,comparison,delete function,the door lock control,and realize mobile app to the door lock control through theWiFi module esp8266 and successfully design a WiFi and fingerprint recognitiontechnology are combined to realize the controlling system of Internet of things.Keywords:Things,WiFi,Microcontroller,fingerprint identification,door lock
