Abstract
In order to solve the problem of data integration difficulties and poor device interoperability caused by inconsistent data formats,diverse protocols and variable devices,this paper designs a maintenance and operation system of common computing environment based on aggregating OPC UA pattern.Firstly,this paper studies the technical characteristics of OPC UA.Then,based on the above research,the overall scheme design is carried out,and a data integration method of aggregation architecture is pro-posed.On this basis,data modeling,communication pattern design and device dynamic discovery mechanism design are completed.Based on the above scheme,this paper carries out development of prototype system and interface,and tests the data delay,which proves the effectiveness of the scheme and has high practicability.关键词
