基于单片机的室内智能照明系统设计

Design of indoor intelligent lighting system based on single chip microcomputer

为了实现对灯具的智能化控制,针对室内照明的要求以及节能的功能,设计了一款以STC89C52微控制器为核心的室内智能照明系统。本系统分为两种模式,手动模式下直接利用PWM调制调光技术对灯光进行控制,自动模式下利用热释电红外感应器感应到有人体行为时,利用光敏电阻采集环境光照强度信息,对其信息进行处理后采用PWM调制调光技术,使得系统能根据环境的光照强度及是否有人体存在等信息实现灯光的自动调节,从而实现室内的智能照明,系统还可以使用红外遥控实现远程操控。本系统结构简单,在实现灯光照明的基本功能的基础上,还可以实现个性化的灯光控制,同时达到节能的目的。

In order to realize intelligent control of lamps, an indoor room with STC89C52 microcontroller as the core for indoor lighting requirements and energy-saving functions is designed.It can be divided into two modes.In manual mode, the PWM modulation dimming technology is used to directly control the light.In the automatic mode, the pyroelectric infrared sensor is used to sense human behavior.Photosensitive resistors collect ambient light intensity information, and use PWM modulation and dimming technology to process the information, so that the system can automatically adjust the light according to the ambient light intensity and human body presence information, thus realizing indoor intelligent lighting, the system has simple structure.On the basis of realizing the basic functions of lighting and lighting, it can also realize the function while achieving energy saving.
