Ad Hoc Stage Light Synchronization Using Master-Follower Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stage light systems lack a feedback mechanism for synchronized operation, leading to out-of-sync displays when packet loss occurs, and existing consoles cannot automatically adjust to maintain synchronization among multiple lights.
Innovation Solution
A stage light system with ad hoc network modules enables a local area network (LAN) among stage lights, designating a master node and follower nodes for time synchronization, using a master node to adjust follower nodes' show frames, and implementing a pending synchronization state to avoid conflicts, with real-time feedback and re-synchronization to maintain time consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If stage lights are manually operated individually, then each light can be adjusted independently, but the operation time and synchronization accuracy deteriorate
Solution Approach 1:
The stage light system performs self-adjustment through automatic control. The controller automatically adjusts multiple stage lights based on preset parameters and timing signals, eliminating the need for manual operation of each light individually. This self-service mechanism maintains individual light adjustability while dramatically reducing operation time.
2Ease of operation
If multiple stage lights are operated manually, then each light can be individually adjusted, but synchronization accuracy deteriorates
Solution Approach 1:
The controller receives feedback signals from the master control device and automatically adjusts each stage light's operation based on these signals. This feedback mechanism ensures that all lights synchronize accurately while maintaining the ability to individually adjust each light's parameters through the control system.
3Illumination intensity
If a large number of stage lights are used, then the show effect is enhanced, but the complexity of control increases
Solution Approach 1:
The controller is designed with multi-functionality to handle various stage lights simultaneously. It can control different types of stage lights (spotlights, floodlights, effect lights) using a unified control interface and communication protocol, reducing control complexity while supporting enhanced show effects through multiple lights.
4Measurement precision
If stage lights are adjusted individually, then precise control is achieved, but the operation efficiency deteriorates
Solution Approach 1:
The control system segments the control of multiple stage lights into independent controllable units, each with precise individual adjustment capabilities. The controller can address and adjust each light separately while managing them as a coordinated group, maintaining control precision across all lights while improving overall operation efficiency through automated batch control.

AI summary
The present invention discloses a stage light system for synchronized operation of a show, including a plurality of stage lights, each stage light has an ad hoc network module; and a controller for controlling the stage light. A LAN is established among at least a portion of the stage lights by the controller through the ad hoc network module, in such LAN one of the stage lights is selected as a master node and the rest are taken as a plurality of follower nodes. All of the stage lights in the LAN are configured to perform time synchronization, and send the current show frame information of the master node to the follower nodes and adjust respective show frames of the follower nodes according to the current show frame information of the master node. By equipping each stage light with the ad hoc network module, the LAN is established, so that the stage lights in the LAN can communicate with each other and the time of the stage lights as the follower nodes can be consistent with the time of the stage light as the master node to achieve time consistency of all the stage lights in the LAN. Meanwhile, the follower nodes can adjust their own show frame according to the current show frame information of the master node, thereby achieving synchronous operation of the show for the stage lights in the LAN.
