Design Of An Intelligent LED Lighting System

With the progress of society and the gradually improved requirement of lighting,the lighting system becomes ingelligent. With the improvement of people’s awarenessof energy saving, LED lighting has become a hot topic. By using lighting controlprotocol and computer technology, LED lighting system of unified management, canachieve energy saving and efficient diversification of control.This thesis gives an intelligent LED lighting solution, the detailed design of themaster unit,salve unit hardwarecircuits, including microcontrollers, communicationinterface design, wireless communication module, the pyroelectric infrared detectionmodule,the brightness detection circuit and LED driven design, to achieve the above-bitmachine, the master system and salve system consisting of intelligent LED lightingsystems. Meanwhile, based on a modified version of HDLC protocol, the thesisdesignes master system and slave system software components, includingsending/receiving command, wireless communication data receiving, dimming andswitching command and control processing program module. These modules work withthe computer software to let the whole intelligent LED lighting system work properly.
