COATING SYSTEM AND COATING METHOD

This application discloses a coating system and a coating method. The coating system determines a target reel to be wound based on state parameters of chucks for clamping reels in a winding apparatus (11); and when it is determined that current coating process parameters satisfy a reel change condition, the winding apparatus (11) is controlled to change reels to wind a material using the target reel. Through the state parameters of the chucks, the coating process parameters, and the reel change condition, automatic switching to the target reel for winding the material in the winding apparatus is achieved, significantly improving the automation level of reel change.
