1、摘要人们生活水平不断提高，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预防抢劫、盗窃等意外事件的需要而设计的果园防盗报警系统。目前市面上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
2、于多用户统一管理。本设计主要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。软件部分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。37InfraredburglaralarmdesigncontrolswhichbasedonthemonolithicintegratedcircuitAbstrac
