1、毕业设计(论文)论文题目:指导老师:吴学娟学生姓名:崔晓强学号:2010010606专业:本文介绍了本次毕业设计的课题汽车防盗报警器的设计。整个系统的功能是通过检测来实现汽车防盗,当没有振动时,保持预警状态,有振动时就报警。本系统主要包插三个部分的电路:振动检测电路、单片机控制电路、报警电路。振动检测电路的主要功能是:检测汽车是否冇振动,当没冇振动时,输出保持低电平,当冇振动时,检测电路产生数字脉冲信号,送到单片机控制电路。单片机控制电路是整个系统的核心部分,它接收检测电路传来的信号,并通过程序来加以处理和控制报警电路,当它接
2、收到的是低电平时,就保持报警电路关闭状态,当它一旦接收到脉冲信号时就开启报警电路。报警电路主要实现声音和光两种报警。本文首先说明了本次设计所能够采用的方案,接着介绍了芯片的功能及其它器件的特性,例如,AT89S52.振动传感器等。然后描述了该系统的组成及其结构。接下来分析了各个电路及整个系统的工作原理及具体工作过程。最后阐述了调试方法以及电路的改进方案,以确保整个系统更加有效地工作和很好地完成本次设计。关键词:振动检测电路单片机控制电路报警电路振动传感器AbstractThispaperpresentsmytaskoftheg
