Coating system and coating method

A coating system, comprising:

• a winding apparatus, a driving apparatus, an unwinding apparatus, and a coating machine controller;
• wherein:
• the driving apparatus is configured to drive a material unwound by the unwinding apparatus to move toward the winding apparatus, and the winding apparatus is configured to wind the material;
• and
• the coating machine controller is configured to acquire state parameters of chucks for clamping reels in the winding apparatus, determine a target reel to be wound in the winding apparatus based on the state parameters, and control the winding apparatus to change reels to wind the material using the target reel when it is determined that current coating process parameters satisfy a reel change condition.
