Description

Technical Field

[0001] The present invention belongs to the technical field of control or regulation systems, and in particular relates to a distributed clock synchronization system and a control method thereof. Background Art

[0002] A distributed clock synchronization system is a system that controls dispersed or distributed systems to maintain unified or synchronous operation. Since dispersed systems may have their own hardware differences, network delays and other factors, the dispersed systems cannot run synchronously. For example, a data center composed of multiple servers, these servers may be distributed in different places. If multiple servers cannot run synchronously, the data center cannot process the data in each system in a unified manner. In this way, the data center's operation and management of data uniformity will be seriously affected.

[0003] In intelligent system management, various systems distributed in different geographical locations or places need to be managed in a unified manner so that each system can run synchronously. The use of a distributed clock synchronization system helps to uniformly operate and manage various decentralized systems so that each system can run synchronously, because the distributed clock synchronization system can monitor systems in different places. For example, when a system in one or several places fails, the distributed clock synchronization system can control or monitor systems in different places in a short period of time. The distributed clock synchronization system can provide unified management for these decentralized systems, ensuring that decentralized or distributed systems can run safely and stably in synchronization.
