基于单片机控制的粉尘检测系统设计
<p>近年来粉尘污染严重危害着人们的生活环境和身心健康,因此必须采取及时有效的措施对环境中的粉尘质量浓度进行检测和控制。本设计应用激光散射原理,基于STC89C52单片机控制,使用PMS3003粉尘传感器采集粉尘质量浓度作为模拟信号,然后将模拟信号通过ADC0809转换器转换成数字信号,再将数字信号传送到STC89C52单片机中,经过处理后在LCD1602液晶显示屏显示实时检测值,键盘按键调节设置
单片机课程的项目化教学改革与实践
<p>针对传统的单片机教学过程中存在的以教师作为主体,理论知识与动手实践脱节,缺乏学习积极性等问题,提出了单片机课程的项目化教学改革。首先介绍了项目化教学的总体思路,然后从教学内容的设计、教学过程的实施和考核评价机制几个方面进行阐述。项目化教学以学生为主,并以项目作为核心,模拟仿真和实物焊接相结合,较大程度上提高了学生的学习兴趣和实践操作的能力,改善了教学效果。</p><p>In view of
单片机控制PID调节的自平衡自行车
<p>针对自行车欠驱动系统的自平衡问题,研制出一种以欠驱动惯性轮系统为物理模型的自平衡自行车,采用拉格朗日法建立了数学模型,进行了动力学分析,得到了有效的核心算法。使用STM32F103c8t6单片机作为核心控制器,通过PID参数的适配控制研究,借助于飞轮在改变加速度过程时产生的反作用惯性力矩,使自行车欠驱动系统渐近收敛于直立的静止平衡状态,车体倾角呈周期性变化,实现了自行车的静止直立自动平衡,并
