【摘要】改革开放以来,我得到了大幅提高,人们对房屋的要求也随着越来越高,具体表现为不仅是家庭的舒适整洁,而且更重要的是更高对住宅的安全的要求。各种盗窃事件的发生也使得人们的防盗意识进一步加强。与此同时,飞速发展的现代计算机和电子技术为家庭安全系统提供了更快发展的可能。
本课题设计了一个操作简单、运行可靠的基于单片机的防盗报警系统。它具有基本的防盗报警功能,能够实现自动探测信号,自动报警功能。自动探测是由热释电红外传感器和微波探测器共同完成,双探测器的应用使得系统的可靠性大大增强,误报率明显降低;自动报警是指当单片机接收到由探测器检测到的入侵信号时,通过程序控制自动输出报警信号引发扬声器和LED发光报警。
本设计由报警探测器部分设计、声光报警部分设计、单片机控制部分设计、信号放大部分设计及相关的驱动电路设计组成。控制核心用的是AT89S51。

【Abstract】In recent years, China's economic developed rapidly, the level of peoples' lives also vastly improved. Peoples also have higher and higher requirement to the their residences. The specific performance is not only in the demand of household’fortable and neat, but also the higher request on residential safety. All sorts of theft events also strengthen the security consciousness of people. At the same time, the rapid development of the puter and electronic technology of family security system provides technical support.
This topic designs a simple and reliable operation of the anti-theft alarm system based on single chip. It has a basic security alarm function ,and it can automatically detect the signal and realize the automatic alarm. Automatic detection pleted by both of pyroelectric infrared sensors and microwave detector. Double detector application makes the system reliability greatly enhanced, it also reduced the rate of false positives. The automatic alarm means that when microcontroller receives the invasion signal by the probe detector, it will automatically output alarm signal to trigger the speaker and LED through the program controlling.
This system includes two parts: hardware design and software design. Hardware design is consisted by the police probe circuit design, sound-light alarm circuit design, single-chip puter control circuit design, signal amplifier circuit design and releva
