中文摘要：

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。

英文摘要：

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 instrumentation 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.
