Wireless control system of reconfigurable flexible process-equipment

The reconfigurable flexible process-equipment developed for machining complex shape and size changes in the scope of large thin-walled parts usually consists of dozens or even hundreds of positioning/support units. During the control process, each unit communicates with the host computer to get control commands and simultaneously feedback internal state information. For large complex system composed of many subsystems, the traditional cable connection based on field bus technology is high control costs and the complexity of the control circuit is hard to build and manage. To solve this problem, this paper puts forward a new way of wireless communication with the cable network technology and drive positioning/support unit in order. This paper focuses on the overall structure of the proposed system, host computer control system, lower computer control system and wireless communication module as well as the implementation hardware circuits and software algorithm. In addition, some solutions of related issues are discussed. The research shows that the proposed system has high stability and reliability, and it provides an effective way to the control and communication of complex system which fully meets the requirements of reconfigurable flexible process-equipment.
