发明名称 NETWORK BASED ELECTRICAL CONTROL SYSTEM WITH DISTRIBUTED SENSING AND CONTROL
摘要 <p>An electrical control system including a plurality of electrical devices having the ability to communicate over a network as well as the ability to interface and work with non-protocol devices and signals that only send/receive an on/off digital signal or send/receive one of numerous analog signals. The electrical devices include sensors (448, 450), transceiver (92), switching devices (544), dimming devices (400) and controlling (90). The devices communicate with one another over a network that may be implemented using one or more different types of media such as twisted pair, power line carrier, coaxial, optical fiber, RF, infrared, etc. The system is particularly suited for lighting control applications within an office, building, room or home. The electrical devices that comprise the control system generally comprise one or more of the following five basic elements: (1) user interface, (2) actuator element, (3) power supply (432) and media connections, (4) communications media and protocol and (5) one or more sensor inputs (448, 450).</p>
