1、河北北方学院毕业论文题目:热释电防盗报警器英文题目:Pyroelectricburglaralarm院系:信息科学与工程学院专业:电子信息工程班级:11401姓名:XXX学号:201142344指导教师:XXX日期:2015年4月15日摘要本论文的课题是设计一款基于单片机的热释电防盗报警器。通过市场调研和查阅相关资料,论证了本设计的必要性和可行性。文中主要论述了该防盗报警器各个模块的详细设计过程。设计从总体方案的设计入手,对红外收发模块、热释电感应模块、报警电路模块等进行了相关的分析、选择及最终方案的确定;首先,通过Protel绘制出热释电防盗报警器的电路图,根据电路图我们可以清晰的了
2、解每个模块的具体情况,并且生成PCB图,之后,我们可以根据PCB图焊接电路、连接电路并进行调试。本设计用单片机作为控制单元,人体感应作为信号触发,近距离红外收发模块作信号传输,蜂鸣器(或扬声器)作报警装置。当单片机收到红外收发模块发出的预警信号后,进入预警状态,热释电感应模块接收到信号时,改变输出电压,单片接接收到它的信号后,发送指令到报警模块使报警器报警。本课题开发设计的热释电防盗报警器体积小、结构紧凑、技术先进、成本低、生产率高、实用性强,普及性高。关键词:单片机;红外收发模块;热释电感应模块;蜂鸣器;LED数码管ABSTRACTThisthesisprojectistodevel
