1、毕业设计(论文)红外报警器的设计姓名:学号:2010132专业:电子信息工程系别:通信工程系指导教师:41摘要随着社会的不断进步和科学技术、经济的不断发展,人们生活水平得到很大的提高,对私有财产的保护意识在不断的增强,因而对防盗措施提出了新的要求。本设计就是为了满足现代住宅防盗的需要而设计的家庭式电子防盗系统。目前市面上装备主要有压力触发式防盗报警器、开关电子防盗报警器和压力遮光触发式防盗报警器等各种报警器,但这几种比较常见的报警器都存在一些缺点。本系统采用了热释电红外传感器,它的制作简单、成本低,安装比较方便,而且防盗性能比较稳定,抗干扰能力强、灵敏度高、安全
2、可靠。这种防盗器安装隐蔽,不易被盗贼发现。同时它的信号经过单片机系统处理后方便和PC机通信,便于多用户统一管理。本设计包括硬件和软件设计两个部分。硬件部分包括单片机控制电路、红外探头电路、驱动执行报警电路、LED控制电路等部分组成。处理器采用51系列单片机AT89S51。整个系统是在系统软件控制下工作的。系统程序可以划分为以下几个模块: 数据采集、键盘控制、报警和显示等子函数。关键词:单片机;红外传感器;数据采集;报警电路41ABSTRACTAlongwithsociety'sunceasingprogressandscienceandtechnology,ec
