Abstract

A control system for allowing remote control of a load. The control system includes a command controller for running a control program that provides a command signal. The command controller has a first wireless interface for transmitting the command signal on a first wireless network. A remote controller has a second wireless interface for receiving the command signals from the command controller via the first wireless network. The remote controller includes a controller for adapting the received command signals for communication on a second wireless network. The remote controller has a third wireless interface for transmitting the adapted command signals via a second wireless network to the load.

Claims

1. A control system for remotely controlling a load comprising:

a. a command controller running a control program for receiving user input via a user interface, generating a command signal based on the user input, and communicating the command signal to a wireless service provider for communication over a first wireless network;

and

b. a remote controller having a first wireless interface module for receiving the command signal from the first wireless network and a second wireless interface module for transmitting at least a portion of the command signal via a second wireless network to the load.

2. The control system according to claim 1 further comprising a load controller having a third wireless interface module for receiving the at least a portion of the command signal from the second wireless network and for controlling the load responsive to the at least a portion of the command signal.

3. The control system according to claim 1 wherein the first, second, and third wireless interface modules comprise transceivers for bi-directional communication between the load controller and the command controller.

4. The control system according to claim 1 wherein the command signal comprises location-identifying information and command-identifying information whereby the remote controller decodes the command signal and directs the command-identifying information to one or more load controllers identified by the location-identifying information.

5. The control system according to claim 1 wherein the first wireless network implements GSM, GPRS, 1XRTT, SMS or a pager network.

6. The control system according to claim 1 wherein the user interface of the command controller authenticates the user before receiving user input and provides the user selective access responsive to the user'"'"'s authentication information.

7. The control system according to claim 1 wherein the load controller includes an electronic ballast coupled to a lamp and the load controller converts the at least a portion of the command signal into an analog output voltage signal for controlling the output of the electronic ballast.
