Modular centralized lighting control system for buildings

摘要

A lighting control system for controlling lights of buildings includes a computer server communicating with programmable master interfaces through an Ethernet communication link. The server is programmed to establish control commands responsive to environment status information. The master interfaces communicate through a primary communication link with programmable input devices which include input interfaces and smart switches, and with programmable output devices. The output devices communicate with a master interface through its primary communication link and also communicate with programmable relay/dimmer devices through a secondary communication link. The relay/dimmer devices control building lights responsive to control commands. The input interfaces communicate with a master interface through its primary communication link and also communicate with ambient light/occupancy sensor devices through a secondary communication link. The ambient light/occupancy sensor devices monitor building zones and establish environment status information. The smart switches include a touch screen LCD used by building occupants for also establishing environment status information. The environment status information and control commands are communicated through the interfaces for thereby controlling the building lights. Each of the interfaces and devices are identified with a unique ID established and maintained by the server. Each unique ID is linked to a virtual graphical representation by the server and displayed on a monitor.
