毕业设计（论文）开门自动灯及防盗报警器院 系 航空电子电气工程学院 专 业 电气自动化 班 级 电气 1103 学 号 202500143030 姓 名 指导老师 2025 年 6 月 1 日摘 要随着社会的不断进展，人们对室内财产以及保密工作的安全要求也越来越高，而比较普遍的防盗措施是安装防盗报警装置，因此防盗报警装置的灵敏度和可靠性是非常重要的。本系统采纳了扫描探测传感器，它的制作简单、成本低、安装比较方便，而且防盗性能比较稳定，抗干扰能力强、灵敏度高、安全可靠。同时它的信号经过单片机系统处理后方便和 PC 机通信，便于用户统一管理。设计利用压电陶瓷片作为声光传感器获得信号并将其转换为电压信号，经场效应管放大后触发由 NE555 集成芯片构成的单稳态触发器和多谐振荡器,输出电压驱动蜂鸣器工作。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。经过调试，实现课程要求。AbstractWith the continuous development of society, people have more and the indoor property and security requirements of confidentiality is higher, and the anti-theftmeasures are common to install anti-theft alarm device, therefore the anti-theft alarm device sensitivity and reliability is very important. The system uses ascanning sensor, it has the advantages of simple manufacture, low cost,installation is convenient, and the anti-theft performance is relatively stable,strong anti-interference ability, high sensitivity, safe and reliable. At the same time it signals through SCM system after processing convenience and PCcommunication, facilitate unified user management. Design is the use ofpiezoelectric ceramics as the acousto-optic sensor signals and converts thevoltage signal, amplified by the FET trigger monostable multivibrator composed of NE555 integrated chip and multi harmonic oscillator, the output voltage drive a buzzer. The design includes two parts o...
