在南水北调中线工程自动化调度系统中,通信系统是重要组成部分之一。而在通信系统设计中,时钟同步的方案设计十分关键。根据南水北调中线工程通信系统具体需求及通信传输网络特点,分析了时钟同步系统的设计准则、时钟同步方式、时钟同步系统结构及时钟同步信号的网络传递方案。通过对时钟同步系统的技术分析,为南水北调中线工程通信系统中时钟同步系统的具体实现提供了解决方案。
In the South-to-North Water Diversion Project automatic dispatching system, communication system is one of the important components. In communication system design, clock synchronization program design is critical. According to the specific requirements of the South-North Water Transfer Project and the characteristics of communication transmission network, this paper analyzes the design criteria, clock synchronization method, clock synchronization system structure and clock synchronization signal transmission scheme of the clock synchronization system. The technical analysis of the clock synchronization system provides a solution for the concrete realization of the clock synchronization system in the midline project of the South-to-North Water Diversion Project.
