1、摘要 I 防盗报警系统的设计 摘 要 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，LED 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 protues 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

2、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。 关键词关键词：单片机；红外传感器；信号接收；报警电路 The Design of Anti-theft Alarm Abstract With the peoples living standards greatly improved , the protection of peoples growing awareness of the anti-theft alarm system fully reflects the value of its application. This design is for the family o

3、f 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.

4、 Anti-theft alarm design includes hardware part and software part. The hardware part of the design including infrared sensor circuit receives the signal, the LED control circuit to control light-emitting and drive the implementation of the implementation of the alarm circuit alarm. The software part of the design including the use of protues simulation software to achieve the role of sound and light alarm, while the use of Pro/E software, anti-theft alarm system of the shell are designed so th
