- Abstract
At Present, the superposition of 25Hz track ircuit and coded track circuit or asymmetrical high voltage pulse track circuit and coded track circuit is commonly used in EMU workshop. In the process of application, it is found that there is poor shunting in use of 25Hz track circuit superposed coded mode, and the code missing occurs in use of asymmetric high voltage pulse track circuit superposed coded mode. The ZPW-2000A·TM frequency shift pulse track circuit contains both high voltage pulse signal and frequency shift signal. The pulse signal can effectively improve poor shunting problem of the 25Hz track circuit. The frequency shift signal sends codes to the locomotive at the same time to solve the code missing problem of the high voltage pulse track circuit superposed coded mode.
