LXI作为新一代模块化仪器总线,具有向后兼容、成本低廉和互操作性强等特点,为构建分布式测试系统和混合测试系统提供了基础；针对LXI仪器需要在网络上被发现的问题,通过研究LXI最新标准规范,提出了一种新的LXI发现协议ZeroConf,从而解决了目前采用的VXI- 11发现协议中发现速度慢、仪器数量以及设备不兼容等网络发现问题；实验结果表明,发现协议ZeroConf实现合理、功能准确,可应用于LXI标准的仪器设备的开发设计之中.%The LAN extensions for Instrumentation (LXI)> a new generation of modular instrumentation bus. Has characteristics of backwards compatibility,low-cost, strong interoperability, which provides a foundation for building a distributed testing system or hybrid testing system. The LXI instruments are needed to be discovered in the network. According to the latest LXI standards, a new discovery protocol called ZeroConf is presented to solve the LAN discovery problems such as low detection speed, small number of instruments and compatibility of instruments, which are the drawbacks of the VXI-11 protocol. The test results show that ZeroConf protocol is reasonable and has right functions, and can be applied to the development and design of LXI standard instruments.
