In the early 80 s of the 20 th century, with the development of computer technology, digital dimming technology gradually appeared and gradually replaced analog dimming technology, and then, communication protocols of various digital transmission forms were successively appeared. In order to enable the interconnection of consoles and dimmers produced by various manufacturers, the USITT (united states light institute for technology) made a data communication protocol DMX512 specifically used between the console and the dimmer in 1986. Through many revisions of the protocol, the DMX512 has become a light control protocol which is widely applied at present.
With the application of LED display screens becoming more common, nowadays more and more large-scale evening stages are beginning to adopt LED display screens. At present, in order to realize the cooperative control of the LED display screen and the stage lamp, the control of the lamp and the LED display screen on the stage is completely separated, the lamp is mainly controlled by a DMX512 console, and the image effect control of the LED display screen is realized by directly operating a display screen controller or operating LED display screen control software on an upper computer. The disadvantages of this control scheme are mainly the following: (1) the control complexity is high, and two persons are required to cooperate or one person is required to operate in a time-sharing manner; (2) the control consistency is poor, and the control synchronism is difficult to ensure no matter two persons cooperate or operate in a time-sharing manner; (3) the cost is higher, and when the control scheme is adopted, if the consistency of the stage effect is ensured as much as possible, two persons are required to cooperate, and the labor cost is inevitably increased.
