摘　　要：基于红外线隐蔽性和保密性高、可昼夜使用,且抗干扰能力强的特点,设计了一种红外报警系统.该系统包括子报警系统和父报警系统2部分,选用被动式红外传感器、单片机及Microsoft Visual Studio 2008等硬软件工具,实现了系统全部功能,并进行了调试和检验.该系统通过热释电红外传感器检测信号,放大处理后作为输出量传递给单片机,单片机控制发声、报警、闪灯、无线传输、串口通信.最终在电脑上报警系统软件实现了接收信号与报警功能,从而达到了异地双报警的目的.According to the advantages of infrared, such as high concealment, confidential, usable day and night, and strong anti-interference ability,etc. , a kind of infrared alarm system is designed. This system consists of two parts： son alarm system and father alarm system. Passive infrared sensor and single-chip microcomputer and Microsoft Visual Studio 2008 are selected to realize all the functions of the system, and test and inspection are completed. The signal is detected by pyroelectric infrared sensor and amplified to enter into the single-chip as inputs. The voice and alarm, end, receive and flashing lights, wireless transmission, serial communication are controlled by single-chip. In the alarm are realized by the alarm system software in the computer. The purpose of offsite dual alarm is achieved.
