摘　　要：LXI仪器是基于以太网接口的新型仪器,而VXI-11发现协议是LXI仪器中的关键标准之一,为了在网络中发现识别LXI仪器,必须实现VXI-11协议。针对LabVIEW中缺乏VXI-11协议工具包的问题,通过分析VXI-11、ONC/RPC和TCP/IP等协议之间的关系,开发出基于LabVIEW的VXI-11库函数,实现LXI仪器的网络识别。实验证明,该方法使LXI仪器能在NIMAX、AgilentI/Olibrary等软件中正确被识别,同时可通过VISA函数接口进行控制,为基于LabVIEW的仪器作为LXI仪器使用提供了基础。LXI instrument is a new instrument based on the Ethernet interface,VXI-11 discovery protocol is one of the key standards used by LXI instrument,In order to identify LXI instrument in the network,VXI-11 protocol must be implemented. By analyzing the relationship between the VXI-11 protocols,ONC / RPC and TCP / IP, VXI-11 library functions based on LabVIEW are designed. The experiment proved that the LXI instruments can be identified correctly in NI MAX and Agilent I/O library, and can be controlled by VISA function interface by this method. Discovery protocol based ong LabVIEW provide a basis for the LabVIEW-based instruments to work as LXI instruments.
