Abstract

A theatrical lighting control network which incorporates a local area network for communication among a number of node controllers and control consoles or devices employed in establising lighting or other effects levels in a theater, film production stage or other performance environment. Use of the network eliminates the requirements for the majority of hardwiring for interconnection of consoles and other controller or monitoring devices to effects controller racks and provides great flexibility in location and relocation of various components of the system.

Claims

1. A method for operating a lighting control system including a local area network having a plurality of connection points, the method comprising:

coupling a first node controller to the network at a first connection point;

coupling at least one peripheral control device to the first node controller;

configuring the first node controller as a peripheral node controller for receiving settings from the at least one peripheral control device and transmitting the settings over the network;

coupling a second node controller to the network at a second connection point;

coupling a plurality of effect control elements to the second node controller; and

configuring the second node controller as a network protocol converter for receiving the settings through the network, translating the settings to a control protocol and transmitting the control protocol to the effect control elements, whereby the at least one peripheral control device can directly control a first one of the effect control elements.

2. A method according to claim 1 further including:

coupling a second peripheral control device to the first node controller; and

configuring the first node controller for receiving settings from the second peripheral control device and transmitting the settings over the network, whereby the second peripheral control device can directly control a second one of the effect control elements.

3. A method according to claim 1 further including:

coupling a control console to the network at a third connection point; and

configuring the control console and the second node controller so that the control console can directly control a second one of the effect control elements.

4. A method according to claim 1 wherein coupling the plurality of effect control elements to the second node controller includes coupling one of the effect control elements to the second node controller through a standard protocol interface.

5. A method according to claim 1 wherein coupling the plurality of effect control elements to the second node controller includes integrating the second node controller into a rack of effect control elements.

6. A method according to claim 1 further including coupling a control console to the second node controller through a standard protocol interface.

7. A method according to claim 1 wherein the settings from the peripheral controller have a first priority, and further including:

coupling a second peripheral control device to the first node controller;

configuring the first node controller for receiving settings having a second priority from the second peripheral control device and transmitting the settings over the network; and

configuring the second node controller for receiving the settings from both peripheral controllers through the network, determining the priority of the settings, translating the settings to a control protocol, and transmitting the control protocol to the effect control elements based on the priority of the settings, whereby both peripheral controllers can directly control the first one of the effect control elements.

8. A method according to claim 1 wherein the settings from the peripheral controller have a first priority, and further including:

coupling a control console to the network at a third connection point for transmitting settings having a second priority over the network; and

configuring the second node controller for receiving the settings from the peripheral controller and the control console through the network, determining the priority of the settings, translating the settings to a control protocol, and transmitting the control protocol to the effect control elements based on the priority of the settings, whereby the peripheral controller and the control console can directly control the first one of the effect control elements.

9. A method according to claim 1 wherein configuring the second node controller includes:

coupling a computer to the network;

transmitting configuration information from the computer to the second node controller over the network; and

storing the configuration information in the second node controller.

10. A method for operating a lighting control system including a local area network, the method comprising:

coupling a plurality of control devices to the network;

coupling a network protocol converter to the network;

coupling a plurality of effect control elements to the network protocol converter, transmitting settings from the control devices to the network;

receiving the settings through the network at the network protocol converter;

translating the settings to control information; and

transmitting the control information to the effect control elements;

whereby a first one of the plurality of control devices can directly control a first one of the effect control elements, and a second one of the plurality of control devices can directly control a second one of the effect control elements.

11. A method according to claim 10 wherein:

a first one of the plurality of control devices is a control console; and

a second one of the plurality of control devices is a remote control unit.

12. A method according to claim 11 wherein the remote control unit is coupled to the network through a peripheral node controller.

13. A method according to claim 10 wherein the control information is standard protocol information.

14. A method according to claim 10 wherein the control information is PWM data for a firing engine.

15. A method according to claim 10 wherein the control information is data for a smart dimmer.

16. A method according to claim 10 further including transmitting feedback information from the network protocol converter to the plurality of control devices.

17. A method according to claim 10 further including prioritizing the settings from the control devices.

18. A lighting control system consisting of:

a single local area network having a plurality of connection points for a structure of control devices, peripheral devices, and effect control elements, said structure comprising;

a peripheral node controller coupled to the network at a first connection point for receiving settings from at least one peripheral control device and transmitting the settings over the network; and

a network protocol converter coupled to the network at a second connection point for receiving the settings through the network, translating the settings to a control protocol and transmitting the control protocol to a plurality of effect control elements, whereby the at least one peripheral control device can directly control a first one of the effect control elements.
