基于单片机控制的高速数据采集与处理系统研究
<p>针对现有单片机的数据处理速率较低不利于高速数据采集与处理的问题,文中研究并设计基于单片机控制的高速数据采集与处理系统。在数据采集方面,使用A/D高速采样芯片实现高速数据采集。为满足高速数据处理与存储的需要,文中使用PC终端的IDE接口硬盘作为系统的存储装置。另外,为协调数据采集与数据处理过程,使用单片机核心控制模块控制高速双口RAM实现高速数据缓存排队,从而实现数据从A/D采样芯片到IDE硬
基于STM32单片机的环境监测仪的设计与研究
<p>为提高对家庭环境质量的有效实时监测,及时保存相关数据,设计采用ARM Cortex-M3内核的STM32F103系列单片机为核心控制器的无线环境监测仪。使用DHT11温湿度模块、甲醛电化学模块、激光式颗粒物传感器以及GSM模块等采集室内的温度、湿度、甲醛浓度、PM2.5数值,通过嵌入式软件编程实现系统对相关数据的获取、计算和显示。通过GPRS无线通信技术,具备FTP连接主流的物联网网站,实现
基于STC89C52单片机的智能扫地机器人设计
<p>利用STC89C52单片机,控制红外避障传感器、按键电路、电机电路、风扇控制电路,实现一款智能化避障吸尘小车设计。通过红外避障传感器检测障碍物方向和距离,当一个方向检测到障碍物时,吸尘车则向反方向转动,从而实现自动避障。在小车的下面安装风扇和储尘盒,实现小车吸尘的功能。经过实际实验,验证了系统具有很好的实用性和稳定性,为自动避障吸尘小车控制系统的开发提供了良好的思路。</p><p>Using
基于单片机小车自动掉头控制系统设计
<p>针对部分小区及公共场所小车掉头难的问题,提出了以STC15F2K60S2单片机为控制核心,以车灯作为掉头控制信号的小车自动掉头控制系统,利用超声波传感器检测小车是否到达转盘,由光敏电阻传感器检测小车的车灯控制信号,通过单片机识别处理,启动电机带动转盘匀速旋转180°,驾驶员无须下车,就能轻松实现小车原地掉头,无需人工操作。系统具有语音提示操作功能,有手动和自动两种工作模式。经测试系统运行稳定
