Coating system and method for airplane coating

The invention discloses a coating system and method for airplane coating. The coating system comprises a composite anti-explosion spraying robot and a suspension platform robot. The composite anti-explosion spraying robot comprises an anti-explosion AGV navigation system, a first spraying robot body, a machine body positioning system, an air supply and filtering system, a paint supply system, a first spraying device and an anti-explosion AGV control system. The suspension platform robot comprises a hanging basket control system and a second spraying robot; the anti-explosion AGV navigation system adopts a laser radar for navigation, and the fuselage positioning system positions an aircraft in a whole spraying workshop and is used for positioning and scanning the aircraft and the surrounding environment for initial map modeling and sending the information to the composite anti-explosion spraying robot and the suspension platform robot for position offset sharing. The composite anti-explosion spraying robot and
