基于C51单片机智能台灯设计原理图+程序源码+仿真+设计文档资料,可做为学习设计参考。 本文介绍了一种基于PWM调光的智能台灯设计。把单片机技术和PWM调光技术结合起来实现台灯光强的调节。即在不改变PWM方波周期的前提下,利用单片机控制PWM的占空比,从而来改变电压的大小实现灯光亮度的调节。 当人体在台灯的范围内且环境光线较弱时,自动感应开灯,且灯的亮度随着环境光线的改变而自动调节,一旦人离开台灯范围,即红外热释传感器检测不到有人时,1分钟后自动熄灯。本设计通过亮度的自动调节和人体检测控制台灯开关来达到绿色节能的效果。同时为了提高本设计的适用范围,还加入了手动模式的控制,在该模式下,台灯亮度由按键调节,这样使得该台灯在一些特殊情况下也能适用。 关键词:单片机;台灯 ;PWM;人体感应 void main() { LED=0; // 指示灯点亮(自动模式指示灯) ret=Get_ADC0832(); // 获取AD采集结果(环境光照强度) AutoControl(ret); // 上电先进行一次自动亮度控制 AutoControl(ret+7);
