基于-单片机的汽车防盗报警系统设计

1、基于单片机的汽车防盗报警系统设计作者：何超专业名称：电子信息科学与技术指导教师：兰英摘要始以/盂普髪爭牛赧编蹩;矍矗护开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盗窃等意外事件的需要而设计 的汽车防盗报警系统。U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，但这儿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、灵敬度高、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

2、机系统处理后方便和PC机通信, 便于多用户统一管理。本设计主要包括硬件和软件设讣两个部分。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AT89S51o整个系统是在系统软件控制下工作的。软件部分可以划 分为以下儿个模块：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。Abstract（章标题，小二号，黑体，加粗，居中，本页开始以 阿拉伯数字1开始编页号，直到全文结束）The people living standard enhances unceasingly, to private p
