Node lamp control method and system for landscape lighting

The invention discloses a node lamp control method and system for landscape lighting, and relates to the field related to intelligent control of landscape lighting, and the method comprises the steps: creating a time synchronization thread, a DMX512 thread and a data routing thread according to a starting instruction of an operating system; obtaining a time synchronization verification result; performing file data verification to obtain a video file data verification result, when the verification result passes, generating a thread blocking instruction, and updating the video file at the same time; blocking a DMX512 task generated by the DMX512 thread, and placing the DMX512 task in a waiting event bit; when the time synchronization verification result is that verification is passed, a first starting instruction is generated, and after the video file is updated, a second starting instruction is generated; and when the first starting instruction and the second starting instruction are received at the same time,
