摘要： EPA是我国第一个拥有自主知识产权的现场总线标准，现已正式成为IEC的PAS文件。作者在参与开发出“基于无线局域网的EPA网络控制系统”的相关设备后，分析和探讨了为适应不同需要的EPA若干无线与有线网段集成的方案。同时，提出了一种符合EPA标准的无线现场总线设备结构的实现模型。从而为实现了EPA进一步向无线工业现场总线进军提供了一定的理论基础。

Abstract: The EPA profile that is the first industry Ethernet profile of China is constituted. It has been a PAS in IEC. After the author developed equipment of EPA network control system on WLAN, the paper analyses and expatiates some methods for an integrated hybrid(wired/wireless) EPA fieldbus to adapt to different conditions, and provides a model of wireless fieldbus equipment framework on EPA. It provides some theory foundation for EPA occupying more market on wireless fieldbus.
