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
基于单片机的可燃性气体报警器的设计
<p>目前,随着天然气使用的普及,用于家庭燃气检测报警的装置已经存在,但是家庭中使用的燃气报警器普遍存在浓度测量灵敏度不够,以及对烟雾和燃气的区分辨别不够灵敏等问题。根据现有技术的不足,设计用MQ-4气体传感器来检测气体,并用单片机控制装置,能够保证检测的灵敏性,并随时显示室内燃气浓度,以便人们观察,并且可通过本地区实际情况调节燃气报警的预设值。该设计大大提高了人们在使用天然气时的安全性。</p>
基于STM32单片机的嵌入式语音识别系统设计
<p>设计了一款以STM32F103为核心的自然语言识别系统,为满足实时语音识别系统对内存资源和运算速度的要求,基于硬件资源合理设计语音处理算法,在嵌入式平台上实现了对孤立词语的语音识别。首先根据背景噪声和语音信号的时域特征差异设定相应门限值,从而实现了对语音信号的端点检测。然后针对语音识别中传统梅尔倒谱系数对语音的高频信息敏感度较低,对语音信号分别提取梅尔倒谱系数(MFCC)与翻转梅尔倒谱系数(
基于单片机的教室智能照明系统
<p>本文主要介绍了一种AT89S52单片机为核心的教室灯光自动控制系统,针对学校商场等室内灯光的控制现状以及大量浪费能源浪费问题详述了系统的硬件设计和软件设计思路。重点研究了热释红外传感器如何检测人体的存在和光敏三极管构成的电路如何检测环境光的强度。根据教室里的自然条件,系统会通过对人体信号的检测和光照强度的信号识别自动加以判断,构成对教室照明回路的智能控制。该系统控制方便可靠,节约成本性价比高
基于STC15F2K60S2单片机的微电网模拟系统设计
<p>文章研究的微电网实验模拟系统以STC15F2K60S2单片机为控制核心,由三相逆变器、滤波电路、电压电流检测电路等电路构成,利用自然数查表法在单片机输出SPWM脉冲信号,采用双极性调制驱动三相全桥逆变电路,实现了在三相对称Y型连接的电阻负载上得到稳定的正弦波交流电的功能。测试表明该微电网模拟系统输出电流、输出电压和频率,满足负载线电流、线电压以及工频的相关要求,且交流母线电压总谐波畸变率少于
