Technical Field
[0001] The present invention relates to the technical field of intelligent power metering, and in particular to a method and system for interacting and managing electric energy meter data based on metering production scheduling. Background Art
[0002] With the gradual advancement of global smart grid construction, the technological development of electricity meters has entered a stage of rapid evolution. Traditional electricity meters mainly rely on mechanical principles for measurement, which are subject to many limitations in accuracy and efficiency. In recent years, the widespread application of electronic electricity meters has made major improvements from hardware to software, enabling them to achieve a qualitative leap in data collection and communication capabilities.
[0003] Modern energy meters can not only monitor electricity usage in real time, but also have remote communication functions, so that data can be quickly and accurately transmitted to the back-end management system. All of this makes energy meters play an increasingly important role in power company dispatch management, load forecasting and troubleshooting. However, although existing energy meters are gradually developing in the direction of intelligence and automation, there are still some deficiencies in fault detection and data management. For example, the current fault detection methods often rely on simple threshold settings and cannot effectively cope with the comprehensive analysis of multi-dimensional data, resulting in high delays in fault identification and false alarm rates. In addition, many systems lack intelligent learning and adaptability, making it difficult to capture gradually changing states. This results in insufficient detection and response capabilities when facing complex faults and emergencies. Summary of the invention
