| To economize lighting electricity and manage lighting system easily,the control quomodo of lighting system should be changed.Power line carrier communication(PLCC) transmits data with the existing power line without any new wiring,so it is cheap and convenient and has a bright application prospect.Based on PLCC,lighting control system is developed.Power line is designed to transmite electrical energy and is not specially used for communication,so using it as communication channel brings many technical problems.The characteristics of power line communication channel are analyzed.Using the communication software SystemView,the modes of spread spectrum modulation and FSK modulation are constituted.Using the power line channel,the modes are simulated. The system scheme is put forward.The circuits of system are designed. Based on analyzing several PLCC protocol, Power Line Communication Lighting Control Protocol is put forward and developed.In the first chapter,the definition and classify and strength of PLCC are introduced.On the basis of the development situation of PLCC and lighting control ,main contents of this thesis is presented.In the second chapter, the feature of noise, impedance and signal attenuation of power line communication channel are analyzed.The mode of power line communication channel is constituted.In the third chapter,the theory of spread spectrum technique and FSK modulation techniques are introduced. Based on SystemView,the modes of the above modulation techniques are constituted.Under the power line channel,the modes are simulated.In the fourth chapter, based on PLCC, the scheme of lighting control system is put forward.The module of carrier communication is designed.The circuits of system are also designed.In the fifth chapter,on the basis of analyzing X-10,CEBUS,LONTALK and EIB protocols,PLCLCP is put forward.The software of lighting control system is programmed. At last,lighting control system is tested by experiment,and the...
