LOAD CONTROL SYSTEM HAVING A BROADCAST CONTROLLER WITH A DIVERSE WIRELESS COMMUNICATION SYSTEM

摘要

A load control system for controlling the amount of power delivered from an AC power source to a plurality of electrical loads includes a plurality of energy controllers. Each energy controller is operable to control at least one of the electrical loads. The load control system also includes a first broadcast controller (180) that has a first antenna (190) and a second antenna (191). The first antenna is arranged in a first position and the second antenna is arranged in a second position that is orthogonal to the first position. The broadcast controller is operable to transmit a first wire less signal via the first antenna and a second wireless signal via the second antenna. Each of the energy controllers is operable to receive at least one of the first and second wireless signals, and to control the respective load in response to the received wireless signal. The load control system includes a plurality of independently-controlled units having commanders for controlling the energy controllers, where the independent units are configured and operate independent of each other. The broadcast controller is also operable to receive digital messages from the commanders and energy controllers and thus to collect data from the commanders and energy controllers of the independent units.The load control system enables system-wide functionality, such as demand response and whole-building time clock functions.
