基于51单片机红外迎宾及人数检测报警系统

基于 51 单片机红外迎宾及人数检测报警系统Based on 51 MCU infrared greeter and number of detection alarm system摘要红外感应式门铃如今常用于店铺门口用于迎接顾客。它可依据顾客的进出状况作出有所差别的反应。主要研究了红外感应技术在我们日常生活中的应用，即感应式门铃。通过对它的研究，学会红外接近开关的原理、电路设计制作流程以及常用元器件的应用情况。设计研究结果表明:本文叙述的电路设计能达到预期所想，当人进入时，扬声器立即发出问候语，而离开则提示有所区别的问候语，增加了时钟及 DS18B20温度检测，可以实时查看当前时间及温度，并且当店内人数过多的时候，通过 SIM800C 模块把店内的信息反馈给店长。关键词:红外接近开关 WT588 语音模块 红外感应式门铃AbstractInfrared doorbells are now commonly used at shop doors to greet customers. It can make a difference according to the situation of customers in and out. This paper mainly studies the application of infrared induction technology in our daily life, namely the induction doorbell. Through the study of it, learn the principle of infrared proximity switch, circuit design and production process and the application of common components. Design research results show that the circuit design of this paper can achieve expected, when people enter the speakers immediately send greetings, while leaving suggest different greeting, increased the clock and DS18B20 temperature detection, real-time can view the current time and temperature, and when the store too, through SIM800C modules to store the information feedback to the manager.Key words:infrared proximity switch WT588 voice module infrared induction doorbell目录第一章绪论......................................................................................................11.1 设计研究的背景和意义.......................................................................11.2 国内外现状......................................................................
