摘 要:论文研究的是LXI(LAN eXtension for Instrumentation)总线[1]下的网络仪器树形图的动态生成、树形图上的节点的管理和远程节点信息的实时获取,是属于LXI网络仪器管理系统中测控平台的一部分,传统仪器测量和管理存在缺陷,难以克服地域的限制,无法达到实时性测试和远程测控,通过该平台,可以实现对远端仪器的实时远程监控、数据采集和节点管理与维护等,系统中除了测控界面还包括后台处理模块和代理模块,在进行数据测量和采集的时候需要使用SNMP的Get和Set操作,执行该操作需要后台模块和代理模块进行交互。通过对该模块进行功能测试,树形图能动态显示并且代理以及代理下的仪器设备的信息也能在界面实时正确显示。This paper studies the dynamic generation of network instruments tree diagram,the management of nodes on the tree diagram and the real-time acquisition of remote nodes information based on the LXI(LAN extension for Instrumentation)bus,which is a part of the measurement and control platform in the LXI-based network instrument management system. The traditional instrument measurement and management has disadvantages,which are difficult to overcome the limitation of region. Real-time test and remote measurement and control are hard to achieve.Remote instruments monitoring,data acquisition,nodes management and maintenance can be realized in this platform. In addition to the measurement and control graphical interface,the system also includes background processing modules and agent modules. When datas are measured and collected,get and set operations in SNMP are used. The finishing of operations needs the interaction between the background module and the proxy module. The tree graph can be displayed dynamically and the information of the agent can also be displayed correctly on the interface by functional testing.
