Design of an Adaptive Scheduling Algorithm for a Warp Knitting Machine Industrial Wireless Network Based on Fuzzy Control

Aiming at resolving the technical bottlenecks existing in current warp knitting machine control systems, such as the distributed industrial wireless networked control system, in this study the architecture of a warp knitting machine industrial wireless networked control system based on the WIA-PA international standard is proposed which provides a design idea for building a „smart factory”. Secondly, according to the WIA-PA specification, an allocation plan of time slots in a super-frame for intra-cluster and inter-cluster communication is given. Third, in order to enhance the real-time access of equipment, expand the network capacity, and reduce the energy consumption of the system, based on the carrier sense multiple access (CSMA) mechanism supported by IEEE STD 802.1 5.4:2006, an adjustment algorithm of the super-frame structure based on fuzzy control was designed. The effectiveness of the design method was verified by simulation.

Mając na celu rozwiązanie technicznych wąskich gardeł istniejących w obecnych systemach sterowania maszynami do dziania osnowowego zaproponowano projekt adaptacyjnego algorytmu planowania dla osnowarki oparty na teorii zbiorów rozmytych spełniający wymagania międzynarodowego standardu WIA-PA. Skuteczność metody projektowania zweryfikowano za pomocą symulacji.
