The Design of anti-theft alarm system based on STC89C51 single chip microcomputer

摘要:

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。本次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。

Abstract:

In order to solve the family anti-theft problem and complete the alarm function of the residence, a family anti-theft alarm system based on STC89C51 microcontroller is designed.The infrared spectrum signal is detected by pyroelectric infrared detector in the residential or key areas.This design is divided into hardware and software, which consists of signal detection circuit, LED lamp and buzzer execution circuit, GSM module and the basic peripheral circuit of the single-chip microcomputer system to form the hardware system, and software by interrupt, timing and other subroutine to control the relevant hardware module to complete the alarm function.The experimental results show that the system can detect illegal intrusion and warn relevant personnel in time, which can effectively guarantee the safety of person and property.
