A Physical Layer Test System And Test Method Of MVB And WTB Equipment

Today’s international and domestic rapid development of high-speed train equipment manufacturing technology enables the Train Communication Network (TCN) standard vehicle equipment market expanding. In order to make the train equipment from different manufacturers can be compatible with each other, TCN device conformant test is particularly important. Today TCN conformant testing research is gradually increasing and achieved certain results in China, but there are few studies for TCN physical layer testing, lack of physical layer testing and certification of test systems and test methods.To solve this problem, we implement integrated test platform according to design of protocol, after we focus our research on description of MVB device physical layer, WTB node physical layer and so on. Our platform is used to achieve conformance test of ESD and EMD MVB device, WTB node device. Through the automation of the testing process, test item interface to select the simplification and standardization of test steps, test platform which achieves high coverage, greatly improves the availability of the test platform.Finally, by testing platform MVB device and the WTB gateway node device, the result verifies the feasibility of TCN device conformance test platform. The conformance platform plays an important role in promoting the development of the localization certification test platform.
