| 摘要: |
| 介绍了由美国IRIG组织发布的用于各系统时间同步的时间码标准。其中应用最广泛的是IRIG-B版本，简称B码。分析了B码的对时机理，指出变电站的智能设备采用B码对时，就不再需要现场总线的通信报文对时，也不再需要GPS输出大量脉冲接点信号给出了一种应用于变电站智能设备的B码对时接口的硬件电路设计及其相应的软件程序流程。现场应用取得了很好的效果。 |

| Abstract: |
| The time code standards for synchronization issued by IRIG are introduced,in which the IRIG-B code is the most popular. The synchronization principle of IRIG-B code is analyzed. When applying IRIG-B code in substation IED,neither communication messages of fieldbus nor multiple pulse signals of GPS are needed. An interface circuit and corresponding software program flow of IRIG-B code synchronization are presented. Site practice shows it effective. |
