摘　　要：EtherCAT主站在传统Windows平台搭建的方案存在成本高、便携性差和开发周期长等问题。对此提出一种基于Linux嵌入式平台搭建EtherCAT主站的解决方案,主站运行在经过RT-PREEMPT优化的Linux操作系统上,使用了开源SOME软件。搭建了主站测试平台,主站与从站的周期性通讯测试和实时性测试表明:该主站的同步性能良好、周期抖动在μs级别、稳定性强,达到了工业对控制系统实时性的要求,为Linux嵌入式平台搭建EtherCAT主站提供了一种新方案。The EtherCAT master station built on the traditional Windows platform has some problems such as high cost,poor portability and long development cycle.To solve these problems,a solution of EtherCAT master station built on the embedded Linux platform is proposed.The master station runs on the Linux operating system optimized by RT-PREEMPT and uses open source software SOME.The test platform of the master station is built,and the periodic communication test and real-time test between the master station and the slave station show that the master station has good synchronization performance,the cycle jitter is atμs level,and the stability is strong,which meets the requirements of real time control system in industry.It provides a new scheme for Linux embedded platform to build the EtherCAT master station.
