1、 I 摘要 本论文课题是开发设计一款基于单片机的电动自行车无线防盗报警器。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。文中主要论述了该无线防盗报警器各 个模块的详细设计过程。设计从总体方案的设计入手，对无线收发模块、信号触发模块、 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；使用 Protel 软件绘制出该 设计的最终方案的电路图，通过 Protel 电路图清晰地表达出该设计各个工作模块电器元 件的连接情况，并通过 protel 电路图生成 PCB 图，为 PCB 电路板的焊接奠定基础，根据 Protel 电路图连接电路并进行硬件调试；使用 Pro|E 软件对产品的外
2、观进行了设计。 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,以使报警器报警，以此来 威慑犯罪分子，达到保护电动自行车的目的。 本课题开发设计的电动车无线防盗报警器体积小、结构紧凑、技术先进、成本低、生 产率高、实用性强，适用于千千万万电动车使用者。 关键词关键词 单片机；无线收发模块；弹簧开关；防盗报警器；扬声器 II Abstract This thesis focuses on the development and des
