Distributed autonomous linkage display LED control method and system

The invention discloses a distributed autonomous linkage display LED control method, which comprises the following steps of S1, initially presetting an LED control program based on a local server, and sending the control program to an LED controller after the control program is generated; S2, receiving a preset LED control program by the LED controller, and establishing data interaction with the distributed lamp controller through a power supply cable; and S3, enabling the distributed lamp controller to receive and process the LED control program and then executes time-phased lightening display of the LED lamps. Through the arranged control system, the system can achieve the advantage of distributed independent control of the on-off time displayed by the LED lamps according to linkage control of LEDs with various powers and by adopting power carrier wave preset joint display information setting, and can be used for setting the display time of all the LED lamps, thereby achieving the purpose that each LED lamp
