摘要
论文首先介绍了PTP协议的开发背景,接着对协议中涉及的时间同步原理、同步时钟和最佳主时钟算法进行了详述。然后就其它传统同步技术,分析了PTP协议的优势,指出PTP协议综合了软硬件同步方法的优点,可以在不需要太多资源的前提下,就能够获得量级在亚微秒级的时钟同步精度。最后,得出研究基于PTP协议的分布式数据采集系统是可行的结论。
The paper firstly introduces the background of the precision time protocol(PTP).Then,it specifies the principles of time synchronization,clock types and best master clock algorithm(BMC)associated with the PTP.Compared with the conventional time synchronization methods based on the software and hardware,this report analyzes the advantages of the PTP.By using the PTP,it can easily obtain the time synchronization accuracy order of sub-microsecond without too much resource.Finally,a conclusion can be drawn that the study on the distributed acquisition system based on the PTP is feasible.
