摘　　要：HDLC协议一致性测试是保证不同厂家生产的HDLC通信设备之间实现互联、互通和互操作的前提;在对协议一致性测试基本工作原理进行简要分析的基础上,提出了HDLC协议一致性测试的基本方法以及测试过程中基于FSM模型的数据收发处理机制;并在实验室环境下构建了一致性测试硬件平台,设计了测试准备、测试执行和测试评估相关环节所涉及的基本软件功能模块,完成了HDLC协议一致性测试的基本功能;实际运行和测试结果表明,所设计的测试系统达到了预期结果;目前,该系统已成功应用于高速动车组上的通信测试,测试案例可以根据实际需求进行添加、删除和修改,提高了一致性测试的灵活性和完备性。The conformance testing of HDLC protocol is a prerequisite that guarantees interconnection, intercommunication and interop eration of communication devices developed by different companies. This paper came up with the basic approach of protocol testing and the data transmission mechanism based on FSM model in testing procedure. Also, the author built the hardware platform of conformance testing in the lab, designed function modules of the software related to testing preparation, testing execution and testing evaluation, and aeeom plished the basic function of conformance testing of HDLC protocol eventually. Practical operation showed that the design was feasible and reliable. The system has been successfully applied in the conformance testing of HDLC railway network.
