毕业论文-基于51单片机的门禁系统设计.docx

辽宁科技大学本科生毕业设计(论文) 第 PAGE \* MERGEFORMAT 16页 基于51单片机的门禁系统设计 摘 要 随着人们生活水平的日益提高，人们对生活质量的要求越来越高，加之国外入室盗窃的情况层出不穷，导致国内人民开始防患于未然，不惜在门上花很大的心思，来大力提升家庭、公司等场所的出入安全。鉴于以上情况，门禁系统应运而生。近年来，随着科技的不断发展，3C技术已日趋成熟，门禁系统已经走入人们生活的日常了，其应用日趋广泛。伴随着相关科学技术的发展，智能门禁的技术也是飞速发展。生物识别技术的成熟，促成了指纹识别渐渐在门禁系统中普遍起来，同样的射频识别RFID功能也逐渐成为门禁系统的主导功能。这一系列技术的发展与成熟，使得门禁系统在我们日常生活中的使用变得更加经济、高效。本系统提供的是以单片机STC89C52为核心，配以射频识别模块（RC522）、液晶显示模块（LCD12864)、指纹模块（ZFM-60）以及电源模块的门禁系统，该系统采用指纹识别和射频识别实现双重防护，可以实现门禁系统的功能，且经济安全。 关键词：单片机;射频识别;指纹识别;门禁系统 ABSTRACT With the improvement of peoples living standards and the increasing demands on their quality of life, coupled with the increasing number of cases of burglary abroad, the domestic people have begun to prevent the problem before it has even occurred, and they have not hesitate to put a lot of thought into the door. To greatly enhance the safety of access to homes, companies and other places. In view of the above, the access control system came into being. This environment promotes the emergence and development of intelligent access control system. In recent years, with the continuous development of science and technology, 3C (computer, control, communication) technology has become more and more mature, access control system has entered the daily life of people, and its application is becoming more and more extensive. With the development of related science and technology, the technology of intelligent access control is developing rapidly. The maturity of biometric technology has contributed to the popularity of fingerprint recognition in the access control system. The same RFID RFID function has gradually become the leading function of the access control system. With the development and maturity of this series of technologies, access control system has become more economical and efficient in our daily life. The system is based on single chip STC89C52 as the core, with RC522, LCD12864, fingerprint module (ZFM-60) and power module entrance guard system. The system
