Multicoil inside solidification combined winding machine, which can wind, solidify inside and extract high-pressure glass reinforced plastic (GRP) tubes, combines three conventional working procedures. The machine toot has four spindles of two groups working coordinately, improving machining efficiency greatly. This paper presents the realization of its control system, including the hardware and software architecture of the winding, inside solidification and extraction subsystems, and the mutual communication among them. Several key technologies such as the realization of openness, multicoil winding for heavy caliber tubes and remote control are also introduced.
