Multiple channel ballast and networkable topology and system including power line carrier applications

摘要: Control systems and methods for independent control of power systems, particularly lighting network branches, separate individual branch components. Multi-branch comprise independently controllable branches that inter-communicate via PLC communications. In each branch, components such as ballasts, local units, sensors, actuators, repeaters, may exchange commands queries a remote unit (BRCU). Alternatively, BRCU manage or arbitrate communications, interact with other BRCUs, units external management systems. Ballasts include multi-channel ballast enables close-loop fixtures, dimmable non-dimmable lamps within fixture. The is facilitated by sampling circuits/sensors co-located controlled fixture lamp. All controllers are preferably implemented using an integrated digital controller. communication carried out direct spread spectrum method eliminates side lobes from cross-correlation function, anti-collision protocol.
