红外线防盗报警器系统设计和实现 通信工程专业

摘 要随着信息化时代进程的加快，人们对于智能防盗的要求越来越高，一般的防盗措施已经不能满足日常需求，高性能的防盗报警器受到了广大民众的喜爱。本论文讲述了智能化光电防盗报警的研究意义，设计并实现了针对家庭、办公室、仓库、实验室等重要场合的红外防盗报警系统。系统由硬件设计和软件设计两部分构成。硬件系统由红外发射电路、红外接收电路、单片机控制电路、声光报警电路、按键设置模块电路等部分组成。当有人进入监控区域时，热释电红外线传感器会探测到人体发出的红外辐射并转变成为微弱的电压信号，经放大后输入到单片机，启动声光报警系统。软件系统主要使用 C语言编写和调试控制程序，给出了相关的程序流程图。该报警系统误报率低，使用安全可靠，成本低廉，具有很强的使用价值。关键词：单片机；热释电红外传感器； 报警电路 ；智能防盗AbstractWith the continuous development and progress of society, people have more and more attention to security issues on the property, now life also have a wide range of security products, some can protect the personal safety of others can protect the property safety, the design is according to the show set a microcontroller based intelligent residential burglar alarm, can the house property safety.Intelligent anti-theft alarm system of this design is mainly realized in the house when no one can set don't open, the house is in a monitoring state, when a sensor detects when someone enters the thief into the house, the control system will control the alarm device for alarm. Through searching related literature summary ideas in the design process design, the design is divided into two parts: hardware design and software design in the design: in hardware design is mainly based on the design task of the hardware diagram of the whole system design, hardware circuit diagram is designed according to the diagram of each module, including the MCU module circuit, pyroelectric sensor module circuit, alarm c...
