红外防盗报警器的设计 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。关键词：单片机；红外传感器；数据采集；报警电路 The Design of Imfrared Alarm Ma Xiao Electronic Information Science and Technology Specialty No: 040524055 Tutor: Ma Shuai Abstract : This system used Pyroelectric infrared sensor. Its manufacture is simple, and its cost is low, and fixing is convenient. Besides, the system has many merits, such as steady guard against theft, and strong antijamming ability, and high thesensitivity, and high reliability. The fixxing of this alarm is covert, which is discovered easily by cracksman. After has been processed by SCM, the signal of alarm communicates with PC, which is convenient for uniform management. This design includes hardware part and software part. The hardware part includes the control circuit of SCM, and the infrared probe circuit,and the alarm circuit, and LED control circuit. The SCM uses AT89C51, the overall system works under the control of the systemsoftware.
