AI Technical Summary

Technical Problem

In IoT systems, unstable network environments can cause intermittent disconnections between gateway devices and cloud servers. Existing technologies cannot promptly identify momentary network outages, leading to delayed data caching, inconsistencies between cloud and local states, a lack of flexibility, an inability to process critical data in a timely manner, and security risks.

Method used

By monitoring network performance metrics between gateway devices and cloud servers, dynamically adjusting thresholds, determining the priority of terminal devices by combining multi-dimensional factors, structuring and classifying data stored during network outages, prioritizing the synchronization of important data, and introducing a master node-based collaborative adjudication process to resolve data inconsistency issues.

Benefits of technology

It improves data integrity during network outages and data consistency after network recovery, enhances synchronization efficiency and system reliability, ensures timely processing of critical data, and avoids data redundancy and state chaos.

Abstract

The invention discloses a data synchronization method and device, electronic equipment and a readable storage medium, and the method comprises the steps: determining a network connection state between gateway equipment and a cloud server according to the network performance indexes of the gateway equipment at a plurality of moments; under the condition that the network connection state is disconnected, first operation data generated by all terminal devices connected with the gateway device are structured and stored in a classified mode; when the network connection state is recovered to connection, the priority of each terminal device is determined based on the multi-dimensional factor, and the first operation data of each terminal device and the second operation data stored in the cloud server are synchronized in sequence according to the priority, so that the integrity of the data on the terminal device during the network disconnection period is ensured, and after the network is recovered, the network connection state of the terminal device is ensured. And consistency of cloud data and local data.
