基于指纹 IC 卡的楼宇门禁系统的设计 Design of building access control system based on fingerprint IC card 内容摘要随着科技的发展和人们生活水平的提高，现今中国社会的家庭物质财产比上一个十年有了质的飞跃。提高防盗意识，提升锁具的安全系数成为当务之急。过去沿用至今的传统的机械锁由于其构造的简单，以及已经许久没有技术更新，导致安全系数下降。被撬的事件屡见不鲜。反观电子锁，它的出现是当今智能时代来临的大势所趋，其保密性高，使用灵活性好，安全系数高。智能门锁就算被强行破门，在失窃的情况下也能配合其他智能设备，如监控，对嫌疑人的生物特征进行采集。对后期案件侦破有重大帮助。本设计旨在设计一款基于 stc89c52 单片机并且集成了指纹认证和IC 卡认证的智能密码锁。本设计用 stc89c52 微控制处理器芯片作为主控，采用指纹识别模块，和 IC 卡认证模块组成的安全认证系统，可通过矩阵键盘输入的电子密码设置指纹密码解锁和 IC 认证两种解锁方式采用 LCD12864 液晶进行显示和交互反馈。测试结果表明，本系统各项功能已达到本设计的所有要求。关键字：防盗安全，智能门锁，stc89c52 单片机，IC 卡AbstractWith the development of science and technology and the improvement of people's living standards, the material property of the family in China has made a qualitative leap over the past decade. It is an urgent task to improve the awareness of anti-theft and the safety factor of locks. In the past, the traditional mechanical lock, because of its simple structure and no technical update for a long time, leads to the decrease of safety factor. There are many cases of being prized. In contrast, the emergence of electronic lock is the general trend of the coming of the intelligent age. It has high security, good flexibility and high safety factor. Even if the intelligent door lock is broken by force, it can cooperate with other intelligent devices, such as monitoring, to collect the biological characteristics of the suspect in the case of theft. It is of great...
