摘　　要：介绍了一种采用红外二极管做发射光源,由光敏二极管接收光的简单的光电报警系统,详细论述了系统的组成原理系统由发射、接收、放大和报警四部分组成,当发射和接收之间的光线被阻断时,系统发出报警信号。An simple photo electricity alarm system is presented in this paper. The infrared diode is made for emission lamp-house. The photosensitive diode is made for the receiver. The composing principle is discussed particularly. The system includes four parts. When the beam is interdicted between emission and receiver, the system will give an alarm signal.
