摘要:本文针对各大高校照明用电浪费情况,设计了一套基于单片机的教室照明节能控制的系统。该系统以AT89C51单片机作为主要控制模块,主要输入包括了教室里的人数和光强,人数检测采用的是热释电红外检测,光强检测采用了光敏三极管;通过对人数和环境光信号的检测,完成对教室照明节能控制,仿真分析验证了所设计系统满足设计要求。该系统具有体积小,控制方便,可靠性高,专用性强,性价比合理等优点,可以满足各大高校的照明要求,达到节能的目的。39752 毕业论文关键词:教室照明;节能控制;传感器;AT89C51
Design of Classroom Lighting Energy-Saving Control System
Abstract: Aiming at the classroom lighting waste in this paper, the design of microcontroller classroom lighting intelligent control system based on. The system uses AT89C51 microcontroller as the control module, using pyroelectric infrared sensors to detect the number of the classroom, the classroom phototriode detection of light intensity; through the detection of the number and the light signal, the simulation analysis shows that the designed system meets the design requirements. This system has the advantages of small volume, convenient control, high reliability, strong specificity, has the advantages of reasonable price, can meet the requirements of energy-saving lighting universities, saves energy to a great extent.
