基于STC89C51单片机的防盗报警系统设计

为了解决家庭防盗问题,完成住宅的报警功能,设计了一种基于STC89C51单片机的家庭防盗报警系统;通过在住宅或重点区域设置布防,系统由热释电红外探测器检测红外光谱信号;防盗报警系统的设计分为硬件和软件两部分,由信号检测电路,LED灯和蜂鸣器执行电路,GSM模块和单片机系统的基本外围电路组成系统的硬件系统,软件则由中断、定时等子程序来控制相关硬件模块完成报警功能;实验结果表明,系统可探测到非法入侵,并及时向相关人员示警,可有效地保障人身及财产安全。

In order to solve the problem of home burglary and complete the alarm function of the house,a home burglar alarm system based on STC89C51 was designed.By setting up arming in residential or key areas,the system detects infrared spectral signals from pyroelectric infrared detectors.The design of the anti-theft alarm system is divided into hardware and software.The signal detection circuit,the LED lamp and the buzzer execution circuit,the basic peripheral circuit of the GSM module and the single-chip system form the hardware system of the system,and the software is interrupted and timed.The program controls the relevant hardware module to complete the alarm function.The experimental results show that the system can detect illegal intrusion and promptly alert the relevant personnel,which can effectively protect the safety of people and property.
