A Method for Achieving Decoupling and Interoperability of Edge-Terminal Interaction in Distribution Internet of Things

This paper elaborates on the "Cloud-Communication-Edge-Terminal" distribution Internet of Things system with Distribution Transformer Supervisory Terminal Unit (TTU) in the substation area as the core, and discusses the achievements of low-voltage distribution networks in Zhejiang. And in response to the problem of uncoupling and interconnecting applications between the edge and Terminal interactions of the distribution Internet of Things, a standardized topology recognition method for physical features and business data interaction content is proposed, and verified through experiments.
