摘　　要：根据IEC9646对协议测试的原理和说明,基于工业以太网(EPA)协议的通信特点及其要求,设计了EPA一致性测试中抽象测试集的层次结构模型,参照树表结合表示法(TTCN)的结构框架和思路定义了一种类形式化语言来描述EPA的抽象测试集,介绍了EPA抽象测试集的生成过程和实现步骤。通过EPA一致性测试系统的实际应用,证明EPA抽象测试集能够完整的包括EPA协议一致性测试的所有内容,根据此测试集设计的测试系统能够准确测试出被测协议实现是否与EPA标准一致。According to the principle and explanation for protocol test in IEC 9646 and based on the characteristics and requirements of Ethemet for Plant Automation （ EPA）, a layer structure model of abstract test suite was designed. With reference to the structure and clue of Table and Tabular Combined Notation （ TTCN）, a kind of formalization language was defined to describe the abstract test suite. Meanwhile, the generative process and realizing steps of the EPA abstract test suite were introduced. The practical application of EPA conformance test system indicates the validity of the abstract test suite, and also verifies that EPA abstract test suite takes in all the contents of the EPA conformance test.
