基于51单片机的智能门禁系统 摘要： 本文主要介绍了基于51单片机的智能门禁系统的设计，原理和实现过程。该系统融合了自动照明、语音提示及录音、智能拨号提示、液晶显示、智能密码锁和温度传感器和查询键盘等接口技术，其智能化的功能，人性化的操作体现了先进的设计理念和学生对单片机接口和外围设备控制知识的深入理解。该门禁系统会在晚上且有人靠近的时候自动照明，液晶屏也只会在有人靠近的时候才点亮，充分体现了节能环保的理念。客人可以通过录音系统留言，主人可以通过输入密码打开门锁，每一步操作都会有相应的液晶显示或者语音提示，非常人性化。另外还设置了报警功能和温度，时钟显示功能，安全又舒心。 关键词： 智能门禁系统，液晶显示，语音提示，红外传感器 Intelligent Access control system Abstract: This paper mainly introduces the 51-series microcomputer based on the intelligence of the design of the entrance guard system, principle and realization process. This system incorporates the automatic lighting, audio and recording, intelligent dial-up hint, liquid crystal display, intelligent locks and temperature sensor and inquires the keyboard interface technology, its intelligent function, the operation of the human reflects the advanced design idea and the students in single chip microcomputer interface and peripheral equipment control a better understanding of the knowledge. The entrance guard system in the evening and someone will near automatic lighting, LCD screen will only in someone close to light up only when, fully embodies the energy conservation and environmental protection concept. Guests can leave a message by the system, the host can through the input password unlock the door, every step operation will have corresponding liquid crystal display or voice prompt, very human nature is changed. In addition also set the alarm function and temperature, the clock display function, safe and comfortable.
