摘要
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,提出无线PC通信卡的软硬件设计方案。根据该方案设计的基金会现场总线无线PC通信卡,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。
In order to meet the demand of foundation fieldbus communication,the software and hardware design of PC communication card based on PCI and nRF401 are presented. The PC Communication Card designed by this method satisfactorily solved the communication problem of local network located in industrial field where the controlling points are distributed widely and the lines of communication are hardly to be laid or have mobile devices.
