摘要:
LXI 网络仪器是以 LXI(LAN eXtension for Instrumentation)作为仪器内部总线,由不同功能的 LXI 模块组成的新型仪器。 LXI 模块本身带有自己的处理器、LAN 接口、电源和触发输入,相较于传统仪器,LXI 网络仪器具有组建灵活、高效、模块化等特点,并且具有较强的扩展性和开放性,允许用户灵活地选用不同厂商和不同类别的仪器设备,而不必仅限于单一厂商和单一类别的仪器设备来构建测控系统。 在测量过程中实现仪器模块的“即插即用”尤为重要。 将一般系统中的“即插即用”机制与 DHCP 动态主机配置协议相结合,提出基于 LXI 网络仪器的自动发现与配置方案。 该方案可实现仪器代理模块和测量模块的自动发现、自动申报、自动加载和自动配置;通过在 LXI 网络仪器平台中的仿真与测量,运行效果良好,设计方案可行。
Abstract:
The LXI network instrument is a new one composed of LXI modules with different functions which is based on LXI (LAN eXtension for Instrumentation) bus. The LXI module has its own processor,LAN interface,power supply and trigger input. Compared with traditional instruments,LXI network instrument has the characteristics of flexible construction,high efficiency and modularity with strong expansibility and openness. It allows users to flexibly select devices from different manufacturers and different categories without having to be limited to a single manufacturer and a single category of instrument and equipment to build the measurement and control system. It
is very important to realize the " plug and play" of the instrument module in the process of measurement. Combining common plug-and-play mechanism with the DHCP,a scheme of automatic discovery and configuration based on LXI network instrument is put forword.The scheme can realize the dection,declaration,loading,and configuration of instrument agent module and measurement module in the
automation. Through simulation and measurement in LXI network instrument platform,the scheme is effective in operation with feasibility.
