LXI网络发现机制的实现

Discovery Mechanism of LXI Standard

LXI是一种基于局域网的新型模块化仪器互联标准,其网络发现机制具有重要的作用。VXI-11规范是LXI发现协议的重要组成部分,它定义了控制器和设备通过TCP/IP网络通信的网络仪器协议,是基于ONC/RPC协议。为了将LXI这一新型网络标准更广泛的推广和应用,针对LXI仪器的网络特性,对VXI-11协议和RPC协议进行了一系列研究,在Windows环境下使用RPC协议来实现VXI-11客户端的发现机制。实验结果表明,分析正确、实现合理、功能准确,可应用于LXI标准的仪器设备开发中。

LXI is a kind of bus standard based on LAN,LXI will develop fast in future.This paper researched the network discovery mechanism which aimed to find the device in LXI standard,analyzed the principle and implement of VXI-11 current used in LXI standard.It is part of a series of applicationnotes designed to explain how find the lan instruments under Windows.The result reasonable design,facility implement and right function,so the mechanism can be used in LXI design.
