The Research On Characteristic Test Of The Interface 'C'between Balise And Lineside Electronic Unit

The signal characteristics of the interface'C', which is the key interface between Balise and Lineside Electronic Unit(LEU), directly affect the correctness of the balise telegram decoding and the safety of train operation. In recent years, with the construction and development of high-speed rail in China, balise has become one of key equipments for train control systems. Therefore, it's very important to test and certificate the characteristics of balise. With the proposition of test specification, the researchers in China are also actively studying and building the test platform of balise. As a part of the testing platform, how to test the characteristics of interface'C' is a urgent problem.Through in-depth understanding and analyzing the contents related to Eurobalise controlling interface test specification FFFIS, I begin to research the characteristics testing of interface'C'. The paper mainly works are as follows:1) Analyzing the working principles and composition structures of balise and LEU. Through the combination of current research in domestic and abroad for the research status of balise, the characteristics of interface'C'have been analyzed and explored.2) Analyzing the testing requirements of balise controlling interface's characteristics.3) Put forward the signal separation and analysis methods of interface'C', and research testing methods according to different signal characteristics.4) Set up the characteristics testing system of interface'C', and simulate the ideal signal of interface'C'. Meanwhile, test and analyse the ideal signal of interface'C'.5) Set up the control interface testing platform, validate the availability of the characteristics testing system, and confirm the correctness of the testing method.
