Ethernet lighting control system and method for stage lamp

Abstract

The invention discloses an Ethernet lighting control system and method for a stage lamp. The system comprises an ARTNET console and a plurality of rows of stage lighting fixtures. Each row of stage lighting fixtures comprises a plurality of stage lighting fixtures connected in series in sequence. Each stage lighting fixture is internally provided with a network switching unit. The ARTNET console is connected with the network switching unit of the first stage lighting fixture in each row of stage lighting fixtures through a network cable. Adjacent stage lighting fixtures in each row of stage lighting fixtures are sequentially connected through a network cable. A network control signal sent by the ARTNET console is transmitted to the network switching units of the first stage lighting fixtures. The network switching unit of the former stage lighting fixture receives and transmits the network control signal to an internal circuit for processing to switch to the network switching unit of the next stage lighting fixture. Compared with the prior art, the system and method of the invention have the beneficial effects of requiring few cables, being simple to control, saving the cost, facilitating the troubleshooting of the point of failure, reducing the workload of installation and maintenance, and being high in network transmission speed.

Description

technical field [0001] The present invention relates to the technical field of stage lights, and more particularly, to an Ethernet lighting control system and method for stage lights. Background technique [0002] With the widespread use of LEDs on stage lighting, the DMX512 wired communication used in the original stage lighting industry standard can no longer meet the development of the industry. There are two main aspects. One is that the transmission speed of DMX512 is slow, and the operation of terminal lamps will be delayed. It has relatively few functional channels, only 512 functional channels, which cannot meet the needs of multiple LED performances. Therefore, the ARTNET protocol combined with Ethernet technology and stage lighting applications has emerged in recent years. [0003] However, Ethernet, which is quite mature in technology, was not originally invented for stage lighting. Because stage lighting has its special application requirements, especially inst...

AI Technical Summary

Problems solved by technology

The use of bus-type network connection is basically the same as the original DMX512. It is a method that is easier to install and wire, but its inherent problems such as slow transmission speed and difficult troubleshooting also determine that it is not suitable for stage lighting applications.

Although the transmission speed of the star network is fast, up to 100Mbps, and troubleshooting is relatively easy, it requires a separate network cable for each lamp to connect to each port of the HUB device. If the distribution range of the lamps is relatively large, the required network cable It is very much, the cost is high and the installation is inconvenient
