Description

Technical Field

[0001] This utility model relates to the field of smart meter technology, specifically to an interactive smart meter communication system. Background Technology

[0002] In the field of smart meter technology, with the development of intelligent power systems, the requirements for accurate power data collection, efficient transmission, and interaction between users and the power grid are becoming increasingly stringent. Traditional meter communication systems often suffer from problems such as single communication methods and fixed communication paths. A failure in any communication link can easily lead to interruptions in data collection and communication, affecting the normal operation of the power system and users' access to electricity consumption information. For example, in some complex power environments, relying solely on a single communication method, such as power line carrier communication (PLC), means that when power lines are interfered with, meter data cannot be uploaded in a timely manner. Power grid management departments cannot accurately grasp users' electricity consumption status, nor can they provide effective electricity services and guidance. Furthermore, traditional meter communication systems are limited in their interactive functions between users and the power grid, failing to meet the needs of modern users for real-time access to electricity information and optimized electricity consumption patterns. Therefore, a new smart meter communication system is needed to solve these problems and improve the stability and continuity of power data collection and communication, as well as the interactivity between users and the power grid.
