摘要:
A load control system 100 for controlling the amount of power delivered from an AC power source to a plurality of electrical loads includes a plurality of independent units 110, 112, responsive to a broadcast controller 180. The independent units 110, 112 may be installed, for example, in separate and at least partially-enclosed rooms in a common building and may be adjacent to each other. Each independent unit 110, 112 includes at least one commander and at least one energy controller for controlling at least one of the electrical loads in response to a control signal received from the commander. The energy controllers (i.e., load control devices) of the first independent unit 110 may comprise, for example, a dimmer switch 210, a plug-in load control device 220, a temperature control device 230, and a contact-closure output pack 240. The commanders of the first independent unit 110 may comprise a remote controller 250, an occupancy sensor 260, and a temperature sensor 270. The energy controllers of the second independent unit 112 may comprise a digital ballast controller 310, a motorized window treatment 320, and a temperature control device 330. The commanders (i.e., wireless transmitters) of the second independent unit 112 may comprise a battery-powered remote control 350, an occupancy sensor 360, and a daylight sensor 370. The broadcast controller 180 transmits wireless signals to the energy controllers of the independent units. The energy controllers operate in different operating modes in response to the wireless signals transmitted by the broadcast controller and are configured to prioritize signal received from the broadcast controller over the signal received from a commander. The operating modes may correspond to demand response compliance requirements received by the broadcast controller from an electric utility 183 or from a demand response remote control 186.

The application discloses a broadcast controller 180 which acquires information about the constituent nodes of one or more independent units 110, 112 with which the broadcast controller 180 is in communication. The independent units 110; 112 include one or more commanders 250, 260, 270; 350, 360, 370 and one or more energy controllers 210, 220, 230; 310 320, 330. For example, the broadcast controller 180 communicates with a first node of a first independent unit 110, where the first node is a first commander 250, 260, 270 or a first energy controller 210, 220, 230. The broadcast controller 180 obtains an address of the first node. Also, the broadcast controller 180 obtains from the first node an address of at least one second node of the first independent unit 110. The at least one second node is a second commander or a second energy controller and the at least one second node is in communication with the first node. The broadcast controller 180 determines if at least one of the first node or the at least one second node is an energy controller. Also, the broadcast controller 180 identifies at least one of the first node or the at least one second node as an energy controller according to the determination. Additionally, the broadcast controller 180 identifies at least one of the address of the first node or the address of the at least one second node as an energy controller address according to the determination. The broadcast controller 180 determines an operational relationship between the first node and the at least one second node. Further, the broadcast controller 180 determines if the first node communicates with a node of the first independent unit other than the at least one second node. The broadcast controller 180 communicates with the at least one second node. Also, the broadcast controller 180 determines if the at least one second node communicates with a node of the first independent unit other than the first node. The broadcast controller 180 determines that all of the nodes of the first independent unit have been identified upon the determinations indicating that the first node communicates with no other nodes other than the at least one second node and the at least one second node communicates with no other nodes other than the first node. The broadcast controller 180 also obtains an address of a third node of the first independent unit 110 from the second node.
摘要:
A multiple location load control system comprises a main device and remote devices, which do not require neutral connections, but allow for visual and audible feedback at the main device and the remote devices. The main device and the remote devices are adapted to be coupled in series electrical connection between an AC power source and an electrical load, and to be further coupled together via an accessory wiring. The remote devices can be wired on the line side and the load side of the load control system, such that the main device is wired 'in the middle' of the load control system. The main device is operable to enable a charging path to allow the remote devices to charge power supplies through the accessory wiring during a first time period of a half-cycle of the AC power source. The main device and the remote devices are operable to communicate with each other via the accessory wiring during a second time period of the half-cycle.
