Abstract:This paper takes fieldbus reliable communication mechanism of CNC system as the research topic, through the overview of CNC system and fieldbus, and the analysis of fieldbus application in CNC system, the needs and challenges of fieldbus communication mechanism are deeply studied. In this paper, a method of system modeling and simulation is proposed to realize the reliability of fieldbus communication of CNC system by means of communication protocol design and optimization, error detection and correction technology, fault tolerance and recovery mechanism design. After analyzing the needs and challenges of fieldbus communication mechanism, this paper gives some countermeasures and suggestions, such as error detection and correction mechanism, network conflict and interference management, fault tolerance and recovery mechanism design.
