利用NTP和标准并口实现高精度时统同步

High-precision time synchronization is achieved by using NTP and standard parallel port

针对高精度时统同步系统硬件成本高的问题,文章提出并设计实现了利用NTP协议和标准并口读取时间信息报文和精确对时脉冲的时间同步方法。实践结果表明,该方法既能保证微秒级的对时精度,又可有效节约硬件成本。

In view of the high accuracy common time-base signal synchronization hardware cost high question,this article proposed and designed realizes has favored the NTP agreement and the standard and the mouth read time information text and precisely to the time pulse time synchronization method.The practice result indicated,this method both can guarantee a microsecond level to the time precision, and may save the hardware cost effectively.
