A Fault-Tolerant Safety Communication Model Based on Dual Ring Bus

摘要：

To meet the transmission security requirements of CNC systems, a message safety communication model, adopting two kinds of fault tolerance algorithms based on CNC dual ring bus, was presented. The safety communication mechanism and algorithms were deeply researched, and the structure of safety message in CNC dual ring bus was proposed. And then mathematic methods were adopted to analyze the performance of the new mechanism. The results proved that our fault-tolerant safety communication model can offer high available and high effective communication support for reliable data service on Fieldbus.
