Hardware Design Of Edge IOT Agent And Resource Allocation Of Docker Computing Considering Monitoring Service Requirements Of Distribution Station Area

On January 13,2019,the State Grid Corporation of China issued the "No.1 Document",which clearly ranked "building a ubiquitous power Internet of things with comprehensive state perception,efficient information processing,convenient and flexible application" as the top priority of the annual work.As the "last kilometer" of the construction of ubiquitous power Internet of things,the distribution station area includes the technical basis of the underlying Internet of things information collection,business data aggregation,terminal communication networking and so on.The application of power distribution Internet of things has a certain foundation,but compared with the strategic goal of "three types,two networks,world-class",the overall construction and application of power distribution Internet of things are still insufficient.in view of the above problems,this paper designs a set of configuration methods of software and hardware of edge IOT agent and container computing resources,completes container management and localized real-time processing of monitoring business in distribution station area,and realizes flexible access,interconnection and local intelligent decision-making of equipment in distribution station area.First of all,this paper analyzes the business requirements of three typical scenarios,such as on column transformer,box transformer and distribution room,and designs a set of "cloud management side end"hierarchical monitoring overall scheme for typical scenarios of distribution station area monitoring.Secondly,aiming at the device perception and communication requirements of the monitoring service in the distribution station area,the hardware design of the edge IOT agent is carried out from four parts:hardware master chip,plug and play communication interface,security encryption unit and power management unit.A multi distribution protocol adaptive conversion method based on mqtt protocol and cloud side interaction mechanism are studied.Finally,aiming at the problem that the traditional distribution transformer terminal can only complete a single subtask at the same time,a set of containerized software architecture that can run multiple tasks at the same time is designed.On the basis of the architecture,this paper analyzes the time sequence logic of power distribution business,constructs the container computing load model such as container computing resources,task priority,time sequence logic and container computing resource allocation,and proposes a container computing resource allocation method considering business priority and time sequence logic on the basis of container architecture,and analyzes the innovation and influencing factors of the method through simulation.To sum up,three typical scenarios of distribution station area monitoring and "cloud management side end" monitoring scheme proposed in this paper,hardware design of edge IOT agent and analysis of cloud side interaction mechanism under monitoring business scenario of distribution station area,software design of edge IOT terminal oriented to time sequence logic of distribution and consumption monitoring business,and resource configuration method of container computing,etc,It provides important practical and theoretical support for the construction of unified IOT standard system for operation monitoring of state grid distribution area.
