摘　　要：为保证MVB设备与TCN标准要求的一致性,在对GB/T 28029—2020中MVB的规范以及规范中MVB物理层一致性测试的项点进行深入研究和分析的基础上,为标准中物理层测试的每个项点设计了测试方案,构建基于PXI平台的MVB网络一致性测试系统。该测试系统将原本分散、独立的各个MVB网络物理层一致性测试项点集成为1个智能测试系统,测试系统的软件能够对MVB物理层一致性测试进行控制,实现测试过程的自动化和MVB一致性测试的智能化,同时整个测试过程的数据得到有效保存,实现了数据的完整性和可追溯性。In order to ensure the consistency between MVB device and TCN standard requirements,on the basis of in-depth research and analysis of the MVB specification in GB/T 28029-2020 and the items of MVB physical layer conformance test in the specification,a test scheme is designed for each item of physical layer test in the standard,and an MVB network conformance test system based on PXI platform is built.The test system integrates the originally scattered and independent MVB network physical layer conformance test items into an intelligent test system.The software of the test system can control the MVB physical layer conformance test,realizing the automation of the test process and the intelligence of the MVB conformance test.At the same time,the data of the whole test process are effectively saved to realize data integrity and traceability.
