Technical Field

[0001] This utility model relates to the field of protocol conversion equipment technology, specifically to a multi-protocol joint control system. Background Technology

[0002] Cultural tourism night tours are comprehensive tourism projects that use modern technology and art such as lighting, projection, sound effects, performances, and immersive experiences to creatively transform and enhance daytime tourist attractions, historical and cultural blocks, parks, towns, etc., at night, thereby extending tourists' stay time, stimulating nighttime consumption, and shaping a unique brand image.

[0003] A typical nighttime tourism project usually includes lighting, laser projection, water features and fountains, sound equipment, stage machinery, and special effects systems such as fog and flame effects. These systems are often provided by different professional manufacturers, each tending to use their familiar or proprietary control protocols. For example, DMX512, Art-Net, and sACN are used for lighting, MIDI or AES67 for audio, while other systems may use Modbus, KNX, or completely proprietary TCP / IP protocols. This "protocol silo" phenomenon makes it difficult for the central control equipment to send unified and precise commands to all subsystems when integrated and synchronized performance is required. Therefore, protocol inconsistency has become one of the core bottlenecks restricting the efficient, stable, and intelligent centralized control of cultural tourism nighttime tourism projects. Utility Model Content In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-protocol joint control system that can support the mutual conversion and integrated control of commonly used lighting signals, audio signals, facility signals, switch signals and network signals in cultural tourism night tour projects.
