| 摘要: |
| 在IEC60870-5-6和IEC61850第10部分:一致性测试,2个关于变电站通信协议一致性标准正式颁布的情况下,描述通信协议的一致性测试模型成为开发一致性测试工具的关键。通过对变电站通信协议一致性测试文本和有限状态机(FSM)的分析,定义并提出了基于扩展有限状态机(EFSM)的变电站通信协议的一致性测试模型的描述方法。该方法突出了信息交互过程的各个事件,克服了传统流程图描述法的繁琐性。以IEC60870-5-103协议的通用分类服务功能"读单个条目的目录"测试为例,分别进行了EFSM和流程图法比较建模,体现出该方法的简练性和严谨性。 |

| Abstract: |
| As two conformance test standards on substation communication protocol,IEC 60870-5- 6 and the tenth part of IEC 61850 have formally issued,the conformance test model describing communication protocol becomes the key in the development of conformance test tools. Through the analysis of conformance testing text of substation communication protocol and FSM(Finite State Machine),a description method of substation communication protocol conformance test model based on EFSM(Extended Finite State Machine) is defined and proposed,which focuses on each event in the interchange of information and avoids the complexity of flowchart description. With the general classification service"Read directory of a single entry" of IEC 60870-5-103 as an example,the comparison of modeling method between EFSM and flowchart illustrates the conciseness and preciseness of EFSM method. |
