| 摘 要： | 设计了一种基于单片机控制LED照明的教室灯光智能控制系统.系统以C8051F340单片机为核心硬件平台,以C语言进行单片机程序设计,使单片机对输入信号进行判断处理,实现了教室灯光控制系统自动开灯、关灯的功能,并通过热释电红外传感器PIR探测室内光强,输出可调占空比的PWM信号,从而实现自动调节以PT4115芯片为驱动的LED灯发光亮度的功能.该系统具有体积小,操作方便,性价比合理的特点,实现节能减排的目的,为未来教室LED灯光智能控制系统的设计提供了一种新思路.

| Abstract: | A MCU-based classroom intelligent LED lighting control system to deal with this situation is proposed in the paper.With a C8051F340 microcontroller as the control platform and the inside control logic implemented by C language,the microcontroller of the lighting control system for classroom can judge the input signal and make necessary decision to turn on/off the lights automatically to save the power.Depending on the light intensity of the classroom detected with the pyroelectric infrared sensor,the system outputs adjustable duty ratio of PWM signal to adjust the luminous intensity of LED lamps based on PT4115 chip automatically.The system is tight,easy to control with reasonable cost and high reliability for energy saving and emissions reduction,and produces a new method to the design of intelligent lighting control systems for classrooms. |
