Problems solved by technology

The disadvantages of this control scheme mainly include the following aspects: (1) The control complexity is high, requiring two people to cooperate or one person to operate in a time-sharing manner; (2) The control consistency is poor, whether it is two-person coordination or time-sharing operation, It is difficult to ensure the synchronization of the control; (3) the cost is high. When using this control scheme, if you want to ensure the consistency of the stage effect as much as possible, you need two people to cooperate, which will inevitably increase the labor cost

Abstract

The invention relates to an LED display screen control system, an LED display screen system and a stage light system. According to the design of the LED display screen control system, a light control protocol interface and a light control protocol signal decoding module are arranged on the LED display screen control system; in this way, the LED display screen control system can be controlled by light control protocol signals and generate image adjustment control parameters to process video image data and obtain processed video image data so as to drive and control an LED display screen, and then real-time adjustment and control of the image effect of the LED display screen can be achieved. When the LED display screen control system is applied to the stage light system, the control range of a light control table can be further expanded to the LED display screen, integrated real-time control of the stage effect is achieved, and site experience of audiences is enhanced; moreover, the complexity of stage scene control can be lowered, the number of allocated stage personnel is reduced, and the cost is further lowered.

Description

technical field [0001] The invention relates to the technical field of lighting control, in particular to an LED display screen control system, an LED display screen system and a stage lighting system. Background technique [0002] In the early 1980s, with the development of computer technology, digital dimming technology gradually appeared and gradually replaced analog dimming technology, and then a variety of communication protocols in the form of digital transmission appeared one after another. In order to enable the consoles and dimmers produced by various manufacturers to be connected to each other, USITT (UnitedStateInstituteforTheatreTechnology, American Stage Lighting Association)) formulated a data communication protocol DMX512 specially used between the console and the dimmer in 1986. After several revisions of this protocol, DMX512 has become a widely used lighting control protocol. [0003] As the application of LED displays becomes more and more common, more an...
