Abstract: The track circuit performs the strategy of fault and planned maintenance until now. In order to overcome the defect of this strategy, this paper presents a state-based mechanism for predictive maintenance of equipment, and designs a kind of architecture and workflow for Prognostics and Health Management(PHM) technology. A PHM system for High-voltage Asymmetric Pulse(HVAP) track circuit is designed based on fuzzy neural network, and two input parameters and four output typical faults are set in this system, the output faults are described with credibility, and the fuzzy inference rule table is gotten according to the expert knowledge and the experience from field. Computer simulation results show that the architecture of PHM is effective.

Key words: track circuit, fault diagnosis, fault prognostics, health management, fuzzy neural network
