Best master clock algorithm of precision clock synchronization protocol

精确时钟同步协议最佳主时钟算法

The optimal master clock of the system is selected quickly and exactly from multi-field devices based on equitable competition.

为满足EPA网络时间同步的高精度要求,建立了一种二维模糊控制器来确定设备自身时钟的优劣层次,系统采用公平竞争的方法从众多现场设备中快速、准确地决策一个时钟性能最好的设备作为EPA系统的最佳主时钟,保证了系统运行的稳定性,降低了本地时钟的波动,使现场设备的时钟同步精度提高到50μs。

The slave clock which gain time stamper by exchanging message with master clock.

本文介绍了IEEE1588精密时钟协议,详细分析了其同步原理,并介绍了一种实现IEEE1588协议的方案,从时钟通过与主时钟交换报文获取时间戳,根据时间戳计算出与主时钟的时间偏差并对自己的时钟进行修正。
