Abstract

Intelligent fault diagnosis based on operational data for railway interlocking systems is now an innovative approach to system maintenance. However, the main barriers to fault diagnosis are high-dimension and long-sequence features of the railway operational data, which makes general deep-learning models inefficient. In this paper, we present a novel deep-learning method of online fault diagnosis for interlocking systems. An online diagnosis server built on a self-attention recurrent neural network (SA-RNN) model was connected to the interlocking system. The problem of long dependency sequences of the data was mitigated by using route logic-based reprocessing. The high-dimensionality problem was resolved via a self-attention mechanism. Finally, experiments demonstrated that the proposed method is persuasive, and the results perform better than traditional models.
