Abstract: An alarm is raised by the train control center because of the inconsistency between state acquisition information and driving control information of signals caused by the interruption of communication with ZPW-2000 track circuits. This paper analyzes this alarm by examining the design principles and technical requirements of the train control center, makes inferences and restores the failure process step by step based on the data on the maintenance terminal, determines the cause of the failure, and proposes a solution.
