Abstract: The intelligent flexible process equipment developed for machining large thi-walled workpieces of an aircraft usually consists of dozens or even hundreds of positioning/support units. Each unit is a complex electro-hydraulic system which needs to communicate with the outside world to get instructions and simultaneously send feedback information. In order to meet the requirements of complex communication control network for such a large complex system including many subsystems, a distributed rank control system of wireless communication with cable network is employed instead of the cable network system because the wired network system is hard to build and manage. The article provides the overall structure of the proposed system, the wireless main control system, network coordination control system and distributed-implementation control systems, as well as the implementation hardware circuits and software algorithm. In addition, some solutions of related issues are discussed. The research demonstrates that the proposed system possesses high stability, reliability and robustness, and it provides an effective solution to the control of a large-scale moving communications and distributes control problems which satisfies fully the requirements of developing an intelligent process-equipment wireless communication system.
