Abstract:
In the actual industry, the causes of track circuit failures vary, but the input data collected may be similar. Aiming at this phenomenon, this paper adopts a hierarchical fuzzy decision tree algorithm to analyze the fault data, which combining fuzzy decision tree algorithm and hierarchical information gain theory. Based on the vertical hierarchical structure of fault types, a fault classification model of 25hz phase-sensitive track circuit is established, and the validity is verified by 6 common fault types.
