智能门禁设计 智能门禁设计摘 要自从改革开放以来中国的经济总量不断增加，伴随着生物识别技术、互联网技术的发展和人们对生活品质要求的增加让智能门禁在我国的市场化迈出了坚实的一步。在以往的日常生活中，无论是开关电灯，执行各种家务等行为都要人们手动，不仅操作繁琐而且也无法满足现代人的需求。在安全防护防护方面，传统的钥匙手动开锁门锁已经稍显过时，且安全性较低，更加安全方便的智能门禁系统更受到人们的青睐。基于红外遥控的智能门禁系统是一种成本低廉可靠性高集自动识别和安全管理于一体的出入管理系统。本次智能门禁设计以 AT89C51 单片机为控制中心，以密码解锁和指纹解锁为解锁方式，并且增加了液晶显示屏提升人机交互水平。关键词：智能门禁系统；单片机；指纹识别；液晶显示 Smart Access Control AbstractIn the past few decades, China ’s GDP has increased significantly, and people ’s living conditions have also improved.,The development of biometrics and Internet technologies has made smart access control a solid step towards marketization in China.. In the traditional daily life, most activities need to be performed manually, which is not only tedious to operate, but also cannot meet the needs of modern people.In terms of safety protection, the traditional manual unlocking of door locks is slightly outdated, and the security is low. This safer and easement intelligent access control system is more loved. This system was integrates automatic identification and security management with low cost and high reliability. This graduation design describes in detail the intelligent access control system of the single chip microcomputer control scheme based on AT89C52 chip. The system provides more robust protection measures such as fingerprint unlocking and password unlocking. Provide people with three-dimensional protection and always guarantee the security of the house.Key words: Smart access control、AT89C52chip、Fingerprint recognit...
