【摘要】 LXI仪器作为基于网络通信的新型仪器,为构建分布式测试系统和混合测试系统提供了基础,如果要在网络上发现LXI仪器,则要求LXI仪器实现VXI-11协议。VXI-11协议要求利用ONC/RPC来实现。针对在Windows或WinCE操作系统平台下开发ONC/RPC程序的库缺乏问题,该文通过分析VXI-11协议与RPC的关系,提出了基于套接字的RPC来实现VXI-11协议的方案,从而解决了由Windows或WinCE系统平台构建的LXI仪器的网络发现问题。该方案具有软件源代码级共享,便于向不同操作系统平台移植的优点。更多还原

【Abstract】 The LAN eXtensions for instruments (LXI) instrument is a new LAN-based instrument. The emergence of LXI instruments provides a foundation for building a distributed testing system or hybrid testing system. If LXI instrument can be discovered by LAN, it must realize VXI-11 protocol which requires using open network computing/remote procedure call (ONC/RPC) to achieve VXI-11 protocol. Because Windows or WinCE is lack of libraries for developing ONC/RPC, through analyzing the relationship between VXI-11 protocol and RPC, a solution is presented to solve LXI LAN discovery, which is based on Socket to realize RPC and VXI-11 protocol. This solution can be easy to transplant the program to different OS platforms.更多还原
