摘要
“互联网+”的远程仪器校准是仪器校准的新模式和研究前沿。针对电力系统传统仪器校准效率低、管理难度大等不足,提出了基于“互联网+”的电力仪表统一远程校准模型,设计任务驱动的交互式远程校准工作模式。基于仪器通信总线与网络协议实现校准数据协议转换、实时传输与信息处理。考虑实际远程校准涉及的多任务流,对远程校准任务进行统一描述,搭建远程校准通用任务服务体系。根据实际校准任务传输模型,结合网络通信服务质量需求,设计仿真实验模型,利用OPNET仿真网络通信质量参数,对比分析不同网络环境下的通信质量,为“互联网+”远程校准系统网络质量的评价和任务优先级分配提供理论与方法基础。
Remote instrument calibration with Internet+is a new mode and research frontier of instrument calibration.Because traditional instruments calibration method in power grid system has poor performances,a unified remote calibration method based on Internet+was designed,and a task-driven interactive pattern was proposed.The calibration data protocol conversion,real-time transmission and information processing methods were realized based on instrument communication bus and Internet network protocol.For the multi-task flow of remote instrument calibration,a unified frame of remote instrument calibration was presented.Then the general task model of remote calibration was established.According to the practical instrument calibration task model,the key parameters of communication quality were simulated with OPNET combined with the network communication service quality estimation.The communication Quality of Service(QoS)in different network environments was analyzed,this method provides a theoretical and methodological basis for the evaluation of network quality and task priority allocation of the“Internet+”remote calibration system.
