一种分布式时钟同步系统设计

摘要

分布式时钟同步系统是分布式系统协同工作的基础，在时间同步技术基础上，设计了一种分布式时钟同步系统。该系统以IRIG⁃B （ InterRange Instrumentation Group）时间基准信号为时间同步源，不仅可以为机器提供高精度时钟信号，在一段时间内保持高精度，而且可以以较小的体积嵌入到产品中，提高便捷性。实验结果表明，该系统可以为机器在不同温度条件下提供高精度时钟信号，而且具有较高的时钟稳定度。%The distributed clock synchronization system is the foundation of coordinated operation of distributed system. Based on the time synchronization technology,this paper designs a distributed clock synchronization system.By using IRIG⁃B(InterRange instru⁃mentation group) time reference signal as time synchronization source,this system can not only provide high⁃precision clock signal for the machine and maintain high precision within a period of time,but also improve the convenience with smaller volume embedding to the product.The experimental results show that the system can provide high⁃precision clock signals in different temperature conditions,and it has higher stability.
