编号: ( 传感器应用技术) 实训论文说明书题目: 红外感应门铃设计院(系): 信息与通信学院专业: 电子信息工程学生姓名: 学号: 指导教师: 李秀东、胡机秀、童有为、王守华 2012 年6月 22日桂林电子科技大学实训(论文)报告用纸摘要本设计的红外线感应电子门铃,可在来客距房门一定距离时发出音频信号,以告知主人“有客来访”。该门铃还可兼作报警器用。电路能探测人体发出的红外线,该红外线感应电子门铃电路由红外线发射电路、红外线接收电路、低频振荡器、音频振荡器和音频输出电路等组成。当人进入感应的区域内,即可发出铃声或者报警声,适用于家庭、办公室、仓库、实验室等比较重要场合的铃声和报警。概述了红外辐射的知识、反射式红外传感器的结构和工作原理。利用反射式红外传感器设计了一种被动式红外报警电路, 分析了该电路的功能和工作原理。反射式红外传感器具有很多的优点, 在人们生活、安全、警戒等装置中应用较广。关键字: 红外线反射式感应门铃桂林电子科技大学实训(论文)报告用纸 Abstract The design of the infrared sensor electronic doorbell can bea certain distance visitors from the door an audible signal to inform the master when guests ing. The doorbell can also double as alarm Used. The circuit can detect the infrared issued by the body, the infrared sensor electronic doorbell circuit by the infrared transmitter circuit, infrared receiver circuit, low-frequency oscillator, audio oscillator, and the audio output position. When people into the induction area, you can send the ringtone or alarm sound for ring tones and alarms in homes, offices, warehouses, laboratories and other important occasions. An overview of the structure and working principle of the infrared radiation of knowledge, reflective infrared sensor. Use reflective infrared sensor designed a passive infrared alarm circuit, the circuit functions and working principle. Reflective infrared sensor has many advantages, widely used in people's lives, safety, and warning devices.
