摘　　要：LXI总线具有高速、灵活等特点,已经广泛应用在仪器仪表中,如何将PXI总线设备快速升级成LXI总线设备成为急需解决的问题。本文介绍了3种通过网络控制PCI接口设备的方法:基于SCPI的网络通信和命令解析、基于寄存器的网络通信和命令解析以及通过远程过程调用(RPC)实现。通过分析比较可知,采用RPC方法时驱动程序和软面板代码基本不需要做任何业务方面的改变,可直接使用,能够最快速度更新软件,继承性最好,并将此方法应用到LXI多通道数字并行测试模块项目中,课题顺利通过验收,取得了很好的效果。LXI bus with high speed,flexibility and other characteristics,has been widely used in instrumentation,and how to upgrade the PXI bus device LXI bus equipment quickly become an urgent problem to be solved.This paper introduces three methods to control the PCI interface device by network：the network communication and command parsing based on SCPI,the network communication and command parsing based on register,and the implementation of the remote procedure call（RPC）.Through the analysis and comparison,using RPC method,the driver and soft panel code do not need to do the basic change in any business,can be used directly,to the fastest speed update software,inherited the best and applied this method to the LXI multi channel digital parallel test module project,project successfully passed the acceptance,achieved good results.
