摘要
研究在通用工控平台上采用PCI总线技术进行车辆综合信息监视设计的方法,提出了一种通过双端口RAM解决电动车辆中央控制主控单元与PCI接口芯片间数据握手的硬件设计方案,并将驱动开发工具WinDriver用户态函数库与LabVIEW图形化编程软件以动态链接库方式嵌套使用,实现了PCI总线底层驱动和上位机监视程序融于一体,将开发的监视系统成功应用于电动车辆上,取得了良好效果。
PCI technology is used in vehicle information monitoring design, using dual- port RAM to implement data exchange between DSP and PCI interface chip. A project of hardware interface design is brought out which finishes address coding of dual - port RAM and local bus arbitration of PCI interface chip by using CPLD, some register configuration of PCI interface chip is given,and the way to develop the PCI bus device drive by using Win Driver tool.
