摘要
为了更好地利用IEEE1588精确时间同步协议,准确地预测时间同步间隔,根据IEEE1588时间同步原理,分析了影响时间同步精度的因素,详细研究了晶振稳定度对时间同步精度的影响。得到了准确的解析表达式,并根据分析得出的解析表达式确定了同步时间间隔的大小。通过实际项目测量,表明理论分析与实际测量结果相符,具有很好的实际应用价值。
In order to make better use of IEEE1588 precisive time synchronization protocol and exactly predict the interval of time synchronization,based on IEEE1588 time synchronization principle,the factors affecting the precision of time synchronization are analyzed,the influence of crystal stability on the time synchronization accuracy is studied,and thus the exact analytical expression is acquired and based on this,the size of the synchronization interval is established.Measurement in actual project indicates that the theoretical analysis is consistent with the practical measurement and is of good practical value.
