LXI网络仪器拓扑图生成的设计与实现
|
摘要
研究了LXI总线下的网络仪器实时拓扑图的动态生成、刷新以及对拓扑图上节点进行各种管理,属于LXI网络仪器管理系统中监管平台的一部分。通过监管平台,可以将网络仪器拓扑直观地呈现并在此基础上远程、实时地对网络仪器进行测控、监管与维护,形成对LXI网络仪器的远程和统一管理,克服了时空和地域的限制。LXI网管系统中除监管模块外,还包括后台和代理模块,在得到网络仪器拓扑或对拓扑上的仪器设备进行SNMP的GET、SET操作时,就需要后台模块来完成监管模块与代理模块之间的间接信息交互。网络仪器的拓扑结构在这里有两级,由局域网内连接的代理以及各代理不同接口连接的不同测量仪器形成,代理即拥有u C/OS-II和Linux OS的ARM系列开发板,测量仪器包括传感器、示波器和函数信号发生器等。
We study the dynamic generation and refreshing of real-time topology of network instruments under the LXI bus and various management of the nodes on the topology map,which are all part of the regulatory platform of LXI network instrument management system. Through the regulatory platform,network instrument topology can be visually presented and on the basis the network instrument can be measured,controlled and maintained remotely and in real-time,formation of LXI instrument remote and unified management,overcoming the limit of time and space. In addition to the supervisory module,the LXI network management system also includes the background and agent modules. When the network instruments topology is acquire,or the SNM P GET or SET operation is performed on the topological devices,the background module is required to complete the indirect information exchange between supervisory module and the proxy module. The topological structure of the network instrument has two levels here. It is formed by different measuring instruments connected by the agents connected in the LAN and different interfaces of the agent. The agent is the ARM series development board with uC/OS-II and Linux OS. The measuring instruments include sensors,oscilloscope and function signal generator.
