摘要 针对地下矿山分布式系统的时间同步问题,本文提出了一种适用于地下矿山分布式系统的高精度时间同步方法,基于IEEE1588-2008时间同步协议研发出了主时钟和从时钟,通过时间同步和频率同步的方式,并在不同网络环境下的进行时间同步测试,整个系统实现了亚微秒时间同步精度,有效解决了地下矿山分布式系统间的实时性问题。 For the problem of time synchronization of distributed system in underground mine,this paper presents a high precision time synchronization method suitable for underground mine distributed system.The master and slave clock are developed based on the IEEE1588-2008 protocol,and time synchronization and frequency synchronization are adopted.Finally,the whole system realizes the sub-microsecond time synchronization precision in different network environments,which effectively solves the real-time problem between distributed systems of underground mines.
