摘要
随着社会的不断发展,人们对室内财产以及保密工作的安全要求也越来越高,而比较普遍的防盗措施是安装防盗报警装置,因此防盗报警装置的灵敏度和可靠性是非常重要的。本系统采用了扫描探测传感器,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。同时它的信号经过单片机系统处理后方便和PC机通信,便于用户统一管理。设计利用压电陶瓷片作为声光传感器获得信号并将其转换为电压信号,经场效应管放大后触发由NE555集成芯片构成的单稳态触发器和多谐振荡器,输出电压驱动蜂鸣器工作。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。经过调试,实现课程要求。

Abstract
With the development of society, people are paying more attention to their indoor property security. In this case, installing an anti-theft alarm devices in a room is the prevalent measure to meet people's need .So sensitivity and reliability of anti-theft alarm device are very important. 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. with PC, which is convenient for uniform is discovered easily by cracksman. After has been processed by SCM, the signal of municates ,designs using as acoustic sensor gain signals and convert to voltage signal, the mosfet amplification triggered by NE555 integrated chips constitute the single and multiple harmonic oscillator steady-state flip-flop, output voltage driver buzzer work,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. missioning, realizing course requirements.
Key words: Alarm;infrared sensor; data collection; alarm circuit;SCM AT89C51.
