摘 要 ：本系统采用了热释电红外传感器，它的制作简单、成本低、安装比较方便，
而且防盗性能比较稳定，抗干扰能力强、灵敏度高、安全可靠。这种防盗器安装隐蔽，
不易被盗贼发现，同时它的信号经过单片机系统处理后方便和 PC 机通信，便于多用户统
一管理。本设计包括硬件和软件设计两个部分。硬件部分包括单片机控制电路、红外探
头电路、驱动执行报警电路、LED 控制电路等部分组成。处理器采用 51 系列单片机
AT89C51，整个系统是在系统软件控制下工作的。

Abstract: The system uses a pyroelectric infrared sensor, making it a simple, low cost,
more convenient installation, and security performance is relatively stable,
anti-interference ability, high sensitivity, safety and reliability. The hidden anti-theft
devices installed, thieves can not easily be found, and it signals processed through the
SCM system to facilitate communication and PC, to facilitate the unified management
of multiple users. The design includes two parts, hardware and software design.
Hardware includes single chip control circuit, infrared sensor circuit, driving the
implementation of the alarm circuit, LED control circuit and other components. 51
series processor AT89C51, the whole system is under the control of the system
software to work.
