摘　　要：红外线防盗报警器以AT89S52单片机为中心逻辑控制模块,通过感知发射电路红外线被遮挡与否来确定是否对外发射报警的警报系统。单片机主要用于控制报警电路的运行,并能同时进行声光报警。本系统主要有以下特点:利用红外线收发管进行检测;安装隐蔽,不易被发现;探测信号采用脉冲信号,节能且抗干扰。系统可以探测到一定范围内的人的闯入,可以应用在安防范围比较确定的情况下。Infrared burglar alarm is a system that using MCU AT89S52 as the central logic control module, by perception the transmission circuit infrared obscured or not, to determine whether the degree of fire alarm outside. MCU Mainly used to control the operation of the alarm circuit and can be simultaneously sound and light alarm. This system mainly has the characteristics： Using the infrared transceiver tube for testing; install hidden, not easy to be found; detecting signal using the pulse signal, energy saving and anti-jamming. This system can detect a certain person within the scope of the intrusion; security can be applied to determine the scope of the case.
