It is mainly reflected in the fact that the smart meters have no backup supply and poor communication capa- bilities, the communication rate of communication architecture in the existing electricity informa- tion acquisition system is slow and the reliability is poor, and the extensibility of the acquisition terminal is not good. These have not met the requirements for high management needs as equip- ment expands and customers pursue high service. Finally, in combination with the development trend of the Energy Internet, it is pointed out that the low-voltage distribution network will be developed in the direction of low-cost construction, rapid demand response, and flexible service expansion in the future. In accordance with the latest requirements of the state grid, the top-level architecture design of the “cloud, network, and terminal” will be formulated. We will cap
