This invention discloses a method and system for testing and processing electrical circuits in medium and low voltage switchgear based on edge-cloud collaboration, belonging to the field of electrical test data processing technology. Through a reinforcement learning dynamic adjustment mechanism, it can adapt to mainstream and proprietary protocols without manual intervention. A multi-dimensional verification and quality labeling mechanism effectively controls the data failure rate. Local parsing, standardization, and verification on the edge side reduces data transmission volume and computational pressure on the cloud side. A reinforcement learning closed-loop feedback mechanism gradually improves system adaptability and parsing accuracy with increasing interaction frequency. Under the federated learning framework, edge devices only upload model parameters, not raw test data. Transfer learning transfers model knowledge from mature protocols to devices using less common protocols, eliminating the need for extensive labeled data. By combining multi-device distributed training with cross-protocol knowledge transfer, and combining model compression with lightweight push protocols, model transmission time and edge update time can be shortened.
