Background

With the continuous development and growth of the field of lighting and power equipment and the increasing activity of the stage performance market, a lighting control system with powerful functions is required to appear. The DMX512 protocol is a general signal control protocol of digitalized equipment in the light industry, is a control protocol commonly used in the field of entertainment light, and in the existing intelligent lamp control system, a DMX512 signal is sent out by the DMX control equipment to control a lamp to achieve dynamic effects of gradual change, jump, color flicker, random flicker, gradual change alternation and the like. However, the traditional control system based on power line carrier is complex in wiring, power lines and data lines need to be connected to the lamps simultaneously during construction, the more the lamps are, the farther the distance is, the longer the wiring of the DXM data lines needs to be increased, the longer the whole communication distance is, the greater the construction difficulty is, and the signal transmission capability can be weakened continuously. The power carrier communication is a special communication method for voice or data transmission using a high-voltage power line (generally, 35kV or higher voltage class in the power carrier field), a medium-voltage power line (10 kV voltage class), or a low-voltage distribution line (380/220V subscriber line) as an information transmission medium, and can transmit analog or digital signals at high speed by using a carrier method, and data transmission can be performed as long as there is a power line. The application of the power carrier disclosed in the patent with the patent application number of CN202010937635.X in the LED direct current power supply comprises a dimming system, wherein the dimming system comprises a signal generator, a coding board and an LED direct current power supply, the output end of the signal generator is connected with the coding board, the output end of the coding board is connected with the LED direct current power supply, the LED direct current power supply comprises a power carrier decoding module and an AD-DC alternating current-direct current conversion circuit, the power carrier decoding module further comprises a coupling transformer and a decoding circuit module, an independent dimming control circuit is omitted, the output voltage or current of any LED direct current power supply can be simultaneously controlled on a power supply link, but the system is only suitable for the LED control system using the direct current power supply at present, is complex and needs to convert the alternating current into the direct current for use, and therefore the cost is high.
