基于单片机的智能小区门禁系统设计 学生姓名： 学生学号： 院 （系）： 电气信息工程学院 年级专业： 电子信息工程 指导教师： 助理指导教师： 二〇一五年五月  摘 要 随着国民经济的发展和经济全球化进程的加快，人们对于高科技服务于生活的要求也越来越高，中国安防产业也取得迅速发展，安防行业领域不断扩大；然而，人们感受着高科技给他们带来的极大便利和在财富不断增长的同时，也带来了许多不安全因素，仅仅依靠单一的物理防范远远不够的。于是智能门禁系统在千呼万唤中应运而生。智能门禁系统是一种综合性的多学科的高科技技术集合，它涉及电子、机械、光学、计算机技术、通信技术、生物统计学等诸多新技术领域。 而智能小区中，作为从进入小区开始的第一道关——小区门禁系统，是其中一个关键。所以此次，我便是基于单片机设计和制作了一个简单的智能小区门禁系统。再采用RC522读卡器模块，射频卡，还有一些基本元件做硬件。软件部分用C语言，还有仿真软件结合完成。 该门禁系统由门禁控制电路，门禁卡，刷卡感应部分，报警响应部分，液晶显示部分，注册注销部分组成。我设计的门禁系统能够实现刷卡进门功能，管理者对该片区的卡还能进行注册和注销的管理，如果有意外发生使系统崩溃，还能及时恢复。 关键词：门禁系统，单片机，IC卡  ABSTRACT With the development of the national economy and the accelerating process of economic globalization , people for high-tech service life requirements are also getting higher and higher . China security industry has developed rapidly , expanding the field of security industry . However , people feel the high-tech give them great convenience and wealth is growing at the same time , also has brought many unsafe factors . So only rely on is not enough to prevent physical single . The intelligent entrance guard system appears in time and again .The intelligent entrance guard system is a set of high-tech technology one kind of comprehensive multidisciplinary , it involves a lot of new technology in the field of electronic , mechanical , optical , computer technology , communication technology , biological statistics , etc . Intelligent residential area , residential entrance guard system is entered from the district started the first road , is one of the key .So this time , I designed and built a simple intelligent access control system based on single-chip . Then the RC522 card reader module , RF card , and some basic elements as the hardware . Software part using C programming language , there is completed based on simulation software . The system is composed of access control card , card reader , the access controller , alarm circuit , liquid crystal display circuit , ca
