Distributed lighting control system

摘要

A lighting system includes a plurality of control modules distributed on the AC power line for remote control of lights within a residential/office building structure. Each control module is hard-wired to an electrical load and is provided with a dimmer and up to four control switches and LEDs for status indication. Each control module has a data decoder, a switch and LED interface, a dimmer driver and processor with memory for independently processing and communicating data signals to the other control modules on the AC power line without the need for a central processor to coordinate the lighting control operation. Every control module is programmable through a programmable module and a PC. The system data downloaded to each control module includes a unique address, a system configuration file and a response file for evaluating system transmission commands. Each control switch may be programmed to control the hard-wired load or any other load in the system.
