Design on IPNCS of Electrical Propulsion Ship Based on Real-time Ethernet

Aiming at disadvantages of Fieldbus technology applied in Integrated Power Networked Control System (IPNCS), the module of NCS transplanted into IPS based on real-time Ethernet was designed. Sequence of channel occupied by real-time nodes was determined by adding software scheduling layer and method of determining priority. The realtime problem of Ethernet and disadvantages of Fieldbus technology were resolved which was consistent with requests of electrical propulsion ship IPS and its development trends. Finally, simulation results demonstrate the effectiveness of proposed method.
