The Design And Implementation Of The Network Communication Module For The Lighting Control Console

With the vigorous development of China's cultural industry, more and more people enrich their spiritual life through watching a variety of stage performances. Traditional stage lighting devices failed to meet the requirements of large-scale lighting control.To address this issue, this paper presents a communication module design for lighting control devices based on Ethernet technology, to integrate devices that run independently on the stage into a unified control system to scale the deployment and usability.This thesis proposes and implements a session-based protocol for managing lighting control devices, to make it work together efficiently in network. It designs a data compression method to reduce the bandwidth requirement for data transmission. In addition, by analyzing the safety requirements of stage lighting control devices, this thesis also present a synchronous backup mechanism to ensure that problems occurred on a light control device do not affect the stage performance. Finally, through the application of the communication module in a lighting control device, this paper provides assessment of its feasibility and practicality, verifying the design of stage light control devices.The result and the significance of this design lie that, network communication module design of stage light control devices can meet user requirements on network integration and safety in an actual stage environment.
