摘要
组建了一种新型星形光纤CAN总线网络。采用塑料光纤(POF)作为传输介质。为存储、处理、调整和优化CAN网络中各参量,设计了光纤CAN总线转USB接口,结合便携式PC机,建立了基于光纤CAN网络的实时数据记录系统。本文重点介绍了光纤CAN总线转USB接口的硬件设计,并详细给出了该接口的驱动程序。
A new Fiber CAN (controller area network)bus network is built with star topological structure.The plastic of fiber is used as the communication medium of CAN bus. In order to restore,process,regulate and optimize parameters in CAN bus,a optical fiber CAN bus to USB interface is designed.Combining portable computer,a real-time data record system is constructed based on optical fiber CAN.This paper puts emphasis on the hardware of optical fiber CAN bus to USB interface.The driver of the interface is given in detail.
