基于AT89S52单片机的教室照明自动控制系统

<p>本课题旨在实现教室照明的智能化,分析了教室照明的目前情况和原理的实现方法,并构思出在52单片机上设计的教室自动照明智能化的思路,并在此基础上提出了实现教室照明的控制方案。该系统采用AT89S52单片机作为控制模块的核心部件,利用HP208人体传感器检测人体的存在,并使用由光敏三极管组成的电路来测量自然光的强度;教室照明开关的条件,是基于是否检测到人和光照的强度并加上定时开关时间。信号和环境照

基于单片机的智能湿纸巾盒的设计

<p>针对湿纸巾易干燥、滋生细菌、冬天刺激幼儿皮肤等问题,提出以52单片机为控制核心,利用温湿度传感器和人体感应传感器提取周围环境信息,通过单片机处理后,控制加热丝加热,显示温湿度信息.按键用于设定温度值,当温度值达到设定值则停止加热,湿度值低于设定值则往纸巾盒中加入液体.打开湿纸巾盒音乐响起,长按S1停止播放,且每天定时紫外线杀毒.通过测试,系统满足以上功能.</p><p>It is propo

基于单片机可语音控制和报时的数字时钟的设计

<p>以STC89C516单片机为主机,STC11L08XE单片机为从机,在传统按键控制式数字时钟的基础上加入语音识别模块和语音合成模块,实现了可语音控制和语音报时的功能。该时钟除具有计时功能外,还具有整点报时、询问报时和闹钟功能;既可用按键控制,也可通过人机对话的形式语音控制。经测试,语音识别率可达75%。不仅适用于广场、车站、客厅等公共场所,也适用于卧室等私人空间。</p><p>With ST

基于AT89C51的智能公交刷卡系统改进设计与实现

<p>为了适应现代化发展,提高公交管理运输现代化水平,设计了一种基于AT89C51的智能公交刷卡系统。系统以单片机AT89C51作为接口电路与刷卡座信息存储装置,将采集到的收费信息、客流信息、刷卡时间、卡内金额与消费金额等信息显示在LCD显示模块中。在软件部分,增加了系统清算功能与客流信息统计功能,通过系统清算功能可以判断公交卡数据是否处于平衡状态,并将非平衡状态下的用户列入黑名单。通过AT89C

基于语音控制的智能家居系统的设计与实现

<p>采用模块化设计,以C语言编程,由LD3320A语音识别芯片以及89C52单片机采集和处理信号,完成人机对话。对各降噪方法在安静和嘈杂环境下进行测试,结果表明,添加垃圾语句语音识别准确率最高。所得结果对于实现非特定人识别的智能语音家居各项功能具有重要意义。</p><p>Using modular design, C language programming, voice identificat
