基于FF协议的无线PC接口卡设计

The design of wireless PC-interface for foundation fieldbus

针对基金会现场总线的通信特点和要求,基于PCI接口和单片无线收发芯片nRF401,提出基于FF协议的无线PC接口卡的软硬件设计方案。根据该方案设计的无线PC接口卡,很好地解决了控制结点分布广、敷设通信线路困难的生产装置或有移动对象的工业现场的局部网络通信问题。

This article proposes a software and hardware design scheme for wireless PC-interface based on PCI and nRF401.The PC-interface designed according to this scheme solves satisfactorily the communication problem of the local work located in industrial fields where the controlling points are distributed widely and the lines of communication are difficult to be laid or where mobile devices are used.
