基于单片机的电动自行车无线防盗报警器设计

摘要

本论文方向是开发设计一款基于单片机的电动自行车无线防报警器。文中论述了该无线防盗报警器各个模块的设计过程。设计从总体方案的设计入手，对无线收发模块、信号触发模块、报警电路模块等进行了分析、选择及最后方案的确定；用Protel软件绘制出该设计的电路图，通过Protel电路图清晰表达出该设计各个工作模块电器元件的连接情况。

本设计用单片机作为控制单元，弹簧开关作信号触发，远距离无线收发模块作信号传输，扬声器（或蜂鸣器）作报警装置。当单片机收到无线收发模块发出的预警信号后，进入预警状态，并当弹簧开关在收到外界振动影响后，接通电路,从而报警器报警，以此来惊吓盗车贼，达到保护的目的。

本课题开发设计的无线防盗报警器体积小、结构紧凑、成本低、生产率高、实用性强。
