基于单片机的多功能 住宅安防报警系统的设计
摘 要
本系统以MCS-51系列单片机STC89C52为微处理器设计了住宅安防报警系统。系统包括硬件和软件设计两个部分，整个系统硬件在软件控制下工作的。硬件部分包括单片机控制电路、传感器采集电路、驱动执行报警电路、LCD显示电路等部分组成。该系统制作简单、成本低，功能齐全、安装比较方便，而且安防性能比较稳定，抗干扰能力强、灵敏度高、安全可靠,另外这种防盗器安装隐蔽，不易被盗贼发现。该系统将极大改善广大家庭的家居安全环境。

Design of the Multi-function Home Security Alarm System Based on the Single-chip
ABSTRACT
This system with MCS-51 MCU STC89C52 microprocessor design residential security alarm system.The system consists of hardware and software design of two parts, the hardware of the whole system works under software control.The hardware part comprises a single-chip control circuit, sensor circuit, driving alarm circuit, LCD display circuit components. The system has the advantages of simple manufacture, low cost, complete function, the installation is convenient, and the security performance is relatively stable, strong anti-interference ability, high sensitivity, safe and reliable, and the anti-theft device concealed installation, is not easy to be the thief found.The system will greatly improve the majority of the family home security environment.
