是否有 PTP(精确时间协议 | IEEE 1588)库?
我的任务是同步时间关键流程,用于记录来自 PLC 的数据与 PTP(精确时间协议,IEEE 1588)时间源。
快速浏览一下可用的库,除了基于 IVI-C 和 IVI-COM 的实现之外什么也没有。
是否有我错过的支持 PTP 的托管库,或者我是否需要找到一种方法来在我的应用程序中使用专为 LabVIEW 设计的 IVI-COM 库?
I've been tasked with syncing a time critical process for logging data from a PLC with a PTP (Precision Time Protocol, IEEE 1588) time source.
A quick look at the available libraries all turn up nothing but IVI-C and IVI-COM based implementations.
Is there a managed library that supports PTP that I missed, or do I need to find a method to use theIVI-COM library that is designed for LabVIEW in my application?

我已从该网站提交了以下答案 http://code.google.com/p /ptpv2d/wiki/Introduction,让我对 ptpv2d 有一个清晰的了解,希望您也能获得关于此的清晰信息。
另请参考此http://code.google.com/p/ptpv2d/
ptpv2d 是GPL 许可的 IEEE 1588 第 1 版、第 2 版和 IEEE 802.1AS 开源代码,包括 Freescale MPC831x 系列处理器的硬件时间戳。
I had reffered, the following answer from this site http://code.google.com/p/ptpv2d/wiki/Introduction, which i gave me a clear idea on ptpv2d, hope you also get the clear information, about this.
Pls refer this also http://code.google.com/p/ptpv2d/
ptpv2d is GPL licensed open source code of IEEE 1588 version 1, version 2 and IEEE 802.1AS including hardware timestamping for Freescale MPC831x family of processors.
我不久前创建了一个 IEEE-1588 库。这在一定程度上是困难的,特别是如果您需要时钟之间良好的同步。好的ptp库涉及大量的统计、预测和信号处理。你可以尝试的最好的方法是 ptpd - 了解 ptp 的工作原理非常简单,它会给你一个好的开始。
I've created a IEEE-1588 library some time ago. It was partly difficult especially if you require good sync between clocks. Good ptp library involves a lot of statistics, prediction, and signal processing. The best you can try is ptpd - it's very simple to learn how ptp works, and it will give you a good start.

PTP 守护进程 (PTPd) 实现IEEE 1588 标准定义的精确时间协议 (PTP)。 PTP 的开发目的是为 LAN 连接的计算机提供非常精确的时间协调。
Look at http://sourceforge.net/projects/ptpd/
The PTP daemon (PTPd) implements the Precision Time protocol (PTP) as defined by the IEEE 1588 standard. PTP was developed to provide very precise time coordination of LAN connected computers.
