摘要
分析了IEC 61850标准和制造报文规范(MMS)之间模型和服务的映射关系。在分析ASN.1的BER编码规则的基础上,提出了MMS编码/解码模块的设计方案,实现MMS协议数据单元(PDU)的ASN.1抽象语法和传送语法之间的转换。基于该模块,编写一个简单的程序,实现了IEC 61850应用层报文编码/解码,分析了具体MMS报文的编码/解码过程。
This paper analyzes mapping relationships between IEC 61850 standard and Manufacturing Message Specification(MMS)on model and service.On the basis of analysis on ASN.1’s basic encoding rules(BER),a design scheme for MMS encoding/decoding module is brought forward,which is used for conversion between ASN.1 abstract syntax and transfer syntax of MMS Protocol Data Units(PDU).A simple encoding/decoding program is finished based on this module,and application message encoding/decoding is implemented.At last,the encoding/decoding of an MMS data flow is analyzed.
