Infrared-alarm-system
本论文设计了由AT89C52单片机为控制核心,用红外线为监测装置的防盗报警系统。该系统中红外对管作为红外线的发射和接收部分。发射部分采用红外发光二极管,而使用光敏三极管作为接收部分,接收红外发光二极管发出的红外线(不可见光)。单片机将通过内部的软件系统检测到接收管的导通或截止状态,并根据检测到的信号状态,进行判断并输出报警信号, 直至按复位按钮或电源开关。声光报警信号由9014三极管驱动构成声光报警电路,进行声光同时报警。电源部分采用变压器将220V交流市经变压器降压,桥式整流器整流,电解电容滤波,三端稳压管78L05稳压,最后得到整机要求的+5V稳定直流电源。实验表明,本系统成功运行。(This thesis is designed by AT89C52 microcontroller as the control center for monitoring device with infrared burglar alarm system. The system of infrared tube as infrared transmitting and receiving section. Emitting portion using infrared light emitting diode, a phototransistor as a receiving portion to receive the infrared ray emitted from the infrared light emitting diodes (not visible). The microcontroller will be detected by the internal software system to the turned on or off state of the receiver tube, and according to the detected signal state, to determine and output an alarm signal until a reset button or the power switch. Audible and visual alarm signal by 9014 transistor drive constitute sound and light alarm circuit, sound and light alarm at the same time. The power part of the transformer 220V AC City by the step-down transformer, bridge rectifier rectifier, electrolytic capacitor filter, three-terminal regulator 78L05 regulator, and finally get the machine requirements+5V)
