摘　　要：针对ACSI信息的解码问题,设计了一种基于MMS报文的解码模块。分析了IEC61850标准和制造报文规范MMS之间的模型映射关系,给出了抽象通信服务接口ACSI和制造报文规范MMS之间的服务映射规则。在分析抽象语法标记ASN.1的BER编码规则基础上,分析了MMS报文的解码过程,并且将MMS协议数据单元PDU的抽象语法描述转换为C语言中的特定结构体,提出了基于MMS的ACSI信息解码模块的设计方法,并基于上述方法设计了解码模块的C语言程序。实验结果表明,本解码模块能够正确实现MMS报文的解码。Focusing on the decodable problem of the ACSI information,the decoding module based on MMS is designed.The mapping relationship of models between IEC 61850 standard and Manufacturing Message Specification (MMS)is analyzed.The mapping rule of service between Abstract Communication Service Interface (ACSI)and Manufacturing Message Specification (MMS)is suggested.On the basis of analysis on ASN.1's basic encoding rules (BER),the decoding process on MMS packet is analyzed,and the ASN.1 abstract syntax of MMS Protocol Data Unit (PDU)is converted to the specific structure of C program language.Based on the above analysis,a designing method of the ACSI information decoding module based on MMS is proposed,and the decoding module of C program is finished.The experimental results show that the designed module can be correctly implemented the MMS packet decoding.
