Control method of spraying equipment

The embodiment of the invention provides a control method of spraying equipment, the spraying equipment comprises a spraying gun, and the method comprises the steps that size information of a to-be-sprayed target cylinder and attribute information of the spraying gun are obtained; based on the size information and the attribute information, the angular speed suitable for rotation of the target cylinder is determined, and the target moving speed suitable for spraying of the spray gun is determined; in response to the fact that the spray gun reaches a first position, the target cylinder is controlled to rotate in situ according to the angular speed, and the first position is located outside the target cylinder or on one bottom face of the target cylinder; and the spray gun is controlled to move along a first track at the target moving speed so as to spray the inner wall of the target cylinder, and the first track penetrates through the interior of the target cylinder and is parallel to the generatrix of the tar
