Abstract: With the improvement of the requirements of the safety operation of railway trains, the train control center equipment has been added with section logic check function, and the centralized signaling monitoring system also synchronously needs to have the monitoring function of the train control center to section logic check function. In order to realize the graphical synchronous display of the states such as train normal occupancy, fault occupancy and loss of shunting in the train control center, the monitoring objects need to be datamation. This paper focuses on the analysis of data implementation of centralized signaling monitoring system to train control section logic check function.
