基于单片机的智能模拟路灯控制系统
<p>随着电力资源的紧缺,以及光污染和雾霾天气的影响,更智能化的路灯设计对人们的日常生活意义重大。本文的智能路灯控制系统是基于单片机的控制器,通过介绍该系统相应的硬件设计和软件设计,实现定时开关和依具体情况是否需要来开关路灯和进行亮度调节,并且具有自检功能,该系统可以提高我国的路灯照明质量和提高利用率。</p><p>With the shortage of electric power resou
基于单片机的直流电机调速控制
<p>设计基于单片机的直流电机转速调速系统。以单片机为核心,加上测速、键盘输入及电机驱动等模块构成整个电机控制系统。对单片机内部资源和外围模块编程实现电机转速的采集和显示、键盘输入目标转速、内部运行增量式PID控制算法得到增量,根据增量对输出脉宽PWM占空比进行调制,使电机达到设定转速并匀速运转。PID控制是闭环控制,可以在转速偏离目标转速时快速调控。通过串口通信输出运行过程中的数据,进而对PID
