毕业设计说明书基于单片机防盗报警系统的设计学生姓名: 学号: 学 院: 专 业: 指导老师: 2025 年 6 月基于单片机防盗报警系统的设计摘要 在我们的日常生活中,安全隐患他随时都有可能发生。安全隐患的发生,它具有突发性,难以预测性,它的发生有时给我们带来毁灭性的打击,甚至造成自身生命和财产的损失。正因为安全隐患具有不可预测性,才有了安防行业的出现,人们才去采纳各种工具和设备预防我们身边安全隐患事件的发生。因此,为了提高我们的防范措施,对防盗报警器的讨论有着十分重要的意义。本系统为了成本低,安装方便,抗干扰能力强,适合大部分人使用,因而采纳了信息与通信工程学院通信工程热释电红外传感器,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。处理器采纳 51 系列单片机AT89C51,整个系统是在系统软件控制下工作的。关键词:AT89C51 单片机、红外线传感器、报警器。A design Based on SCM Anti-theft Alarm System AbstractIn our daily life, safety hidden danger he may happen at any moment. The potential safety hazard, it has a sudden, unpredictable, it happened sometimes bring us a devastating blow, even cause the loss of life and property. Because the potential safety hazard is unpredictable, only the security industry, people just to use various tools and equipment to prevent us security events. Therefore, in order to improve our preventive measures, the anti-theft alarm system research is very important.This system for low cost, convenient installation, strong anti-interference ability, suitable for most people to use, so the pyroelectric infrared sensor, the signal after monolithic integrated circuit system processing convenient and PC communication, is convenient for uniform management. The design includes the design of hardware and software in two parts. The hardware part comprises a single-chip control ci...
