System ArchitectureThe ECS™ is based on the networking of devices, historically viewed as The Energy Control Unit (ECU), an embedded processer, automatically and uniquely addresses each I/O Module in the network of ballasts and sensors using proprietary communication technology called GreenBus™. The ECU collects and processes information received from the sensors and distributes commands to individual ballasts. ECU's are linked to existing local area networks (LANs) to provide personal lighting control on each user's personal computer. A designated building automation PC on the network operates Central Control Software for overall system configuration and monitoring. The system is connected independently of existing lighting electrical circuits for minimized installation cost and maximum flexibility. GreenBus™ CommunicationsECS™ incorporates Encelium's low cost and robust bus technology called GreenBus™ to communicate between the ECU and all ballasts, controls and sensors. GreenBus™ technology has the reliability of RS485 yet is designed specifically for this application to transmit energy data to hundreds of nodes in a daisy chain fashion. It also integrates a power supply over the bus network to operate lighting controls and sensors. This eliminates the extra expense of line voltage wiring and optional power packs for occupancy and photo sensors. GreenBus™ uses standard CAT3/CAT5 communication cable, prefabricated with RJ45 "click-and-go" connectors for minimum installation time. |
independent components, such as electronic dimming ballasts, photo and occupancy sensors and hardware controls. Interconnection of the devices is accomplished using a standard quick-linking network cable and facilitated by a Universal Input/Output Module (I/O Module) installed at each location.
