在基于IEC 61850的数字变电站的运行与维护中，采样值报文蕴含着变电站的一次设备测量所获得电压，电流等重要信息，其为工作人员了解设备运行状况，并作出相应判断及发出控制命令提供了重要的依据，是整个变电站正常运转的重要特征指标。本文在对IEC 61850-9-2报文的数据帧结构、编码的方式以及传输协议堆栈作详细分析的基础上，提出了对采样值报文解码的可行思路并在LabWin?dows/CVI的开发环境中完成了解码程序的编写，最后利用未解码的采样值报文对编写的解码程序进行了仿真与验证。

In the operation and maintenance of the digital substation based on IEC61850, sampled value message contains voltage, current and other important information of the substation measured by the first device. It is the basis for Staff understanding the equipment operating conditions, making appropriate judgments and issuing control commanding. And it is also the important characteristic index of substation in normal running. In this paper, on the basis of detailed analysis of data frame structure, way of coding and transmission protocol stack of IEC 61850-9-2 message, Presented the decoding feasible ideas of the sampled value message and completed the decoding program written in LabWindows/ CVI development environment, used not decoded samples messages to simulate and test and verify at last.
