Abstract: With the development of power grid construction and the continuous growth of the scale of distribution station buildings and equipment, in order to support the development of power grid business applications, more challenges have been put forward to the practicality of edge Internet of things (IOT) agents, and the conventional containerization technology route has appeared a certain bottleneck. Through the introduction and selection of containerization technology, this paper puts forward the lightweight design idea based on the conventional containerization architecture of Kubernetes. The research results of this paper greatly reduce the occupation and consumption of hardware resources by the edge IOT agent device, and realize cloud edge end business collaboration, data collaboration and intelligent collaboration. At the same time, the planning and design of business application app and AI visual learning model algorithm library are carried out on the edge side, which better meets the support of distribution network operation inspection business.
