Analysis of Station Electrocoderised Entrance Current Testing and Adjustment
This paper describes that by implementing coding on the 25Hz phase sensitive track circuit inside the station and overlaying ZPW-2000 coding equipment,the 25Hz phase sensitive track circuit can transmit frequency shift signals based on the display of the signal machine in front of the train operation,while monitoring the idle and occupied status of the section.The size of the entrance current is a key parameter for the locomotive to receive coded information,which needs to be tested and adjusted to the standard value.
