随着人们生活水平的大幅度提高，人们的保护意识不断增强，防盗报警系统便
充分体现了其应用价值。防盗报警系统的设计便是为满足现代住宅防盗的需要所设
计的家庭式电子防盗系统。
防盗报警系统采用了热释电红外传感器，这种防盗器安装隐蔽，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。防盗报警系统设计
包括硬件和软件设计两个部分。硬件部分设计主要包括红外探头电路接收信号，LE
D控制电路控制发光及驱动执行报警电路执行报警等。软件部分设计主要包括使用p
rotues仿真软件能够实现声光报警的作用，同时运用Pro/E软件对防盗报警系统的
外壳进行设计从而使防盗报警系统的设计更加完善。

The Design of Anti-theft Alarm
Abstract
With the people's living standards greatly improved , the protection
of people's growing awareness of the anti-theft alarm system fully
reflects the value of its application. This design is for the family of
electronic security systems designed to meet the needs of modern
residential burglar.
Anti-theft alarm system used Pyroelectric infrared sensor,the fixing
of this alarm is covert, after has been processed by SCM, the signal of
alarm communicates with PC, which is convenient for uniform management.
Anti-theft alarm design includes hardware part and software part. The
hardware part of the design including infrared sensor circuit receives
