基于Gsk-Link的现场总线通讯技术方案研究

Research on Fieldbus Communication Technical Solution Based on GSK-Link

本文基于自主研发的Gsk-Link现场总线,从物理层、报文类型、工作时序、数据传输及诊断故障点等多个方面进行了现场总线通讯技术方案的研究。此方案优化实现了大数据传输、主站连接32个从站以上、一个从站包含多个伺服轴的数据及快速诊断从站故障点等关键技术设计,并在数控系统、机器人系统、伺服驱动及焊接从站卡中应用了该Gsk-Link现场总线新技术方案,验证了这种新技术方案的可行性,为现场总线的设计提供了一种新的设计思路。

Based on the GSK-link fieldbus protocol independently developed,the communication technology solution studied from physical layer,message type,working sequence,data transmission and fault diagnosis.The Solution has realized the key technologies such as big data transmission,more than 32 connections between master station and slave station,one slave station include the datas of multiple servo axis and rapid diagnosis of fault point.To verify the feasibility of this new technology solution.It has applied in CNC system,robot system servo drive and welding slave station card.The communication technology solution provides a new design scheme for fieldbus.
