基于单片机控制红外报警系统毕业设计论文.doc

PAGE 毕业设计 [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。 Infrared burglar alarm design controls which based on the monolithicintegrated circuit Abstract : The people living standard enhances unceasingly, to private property protection consciousness in unceasing enhancement, thus set the new request to the security measure. This design is to satisfy the prevention to rob the orchard security alarm system which, the burglary and so on accident needs to design. At present in the market condition equips mainly has the pressure totouch the hair style burglar alarm, the switch electron burglar alarmand the pressure shields light the hair style burglar alarmand so on each kind of alarm apparatus, but these kind of quite commonalarm apparatuses all have some shortcomings. This system used hashotly released the electricity infrared sensor, its manufacturesimple, cost low, installm the antijamming ability strong, thesensitivity high, safe was reliable. This kind of security installmenthiding, was not easily discovered by the bandits and thieves.Simultaneously its signal after monolithic integrated circuit systemprocessing the convenience and P the C machine correspondence, isadvantageous for the multiuser unification management. This design designs two parts including the hardware and software. Thehardware partially including the monolithic integrated circuit controlcircuit, infrared pokes head in the electric circuit, the actuationexecution alarm circuit, the LED control circuit and so on the partialcompositions. The processor uses 51 series monolithic integratedcircuits AT89S51, the over
