【摘要】：EtherCAT是目前最高速的工业现场总线网络。由于其高带宽利用率,低堆栈延迟、低交换机延迟等优点,近些年被广泛应用于数控机床系统。为满足EtherCAT主站间的通信,进一步扩展EtherCAT组网功能,为构建EtherCAT工业复杂网络提供技术支持,在不影响原有主站与从站通信功能情况下,设计了支持主站与主站之间通信的新协议,扩充IGH开源驱动功能,在AM3358处理器硬件平台上实现了EtherCAT主站与主站的通信。分别在实时RT-Patch linux系统和原生linux系统中对设计方案进行测试,结果表明该方案运行稳定且可以满足主从、主主之间相互通信,满足了工业组网需求。为实现EtherCAT数控系统复杂网络的建立和大数据的快速采集,解决了主站与主站之间通信的关键问题。
[Abstract]:EtherCAT is the most high-speed industrial fieldbus network, because of its high bandwidth utilization, low stack delay, low switch delay and other advantages. In recent years, it has been widely used in CNC machine tool system. In order to meet the communication between EtherCAT master stations, the function of EtherCAT networking is further expanded. In order to provide technical support for the construction of EtherCAT industrial complex network, a new protocol is designed to support the communication between master station and master station without affecting the communication function between master station and slave station. Extend IGH open source driver functionality. The communication between EtherCAT master station and master station is realized on the hardware platform of AM3358 processor. The design scheme is tested in linux system and native linux system. The results show that the scheme runs stably and can satisfy the master-slave communication and meet the needs of the industrial network. In order to realize the establishment of the complex network of EtherCAT numerical control system and the fast acquisition of big data. The key problem of communication between master station and master station is solved.
