For enhancing the troubleshooting efficiency of a track circuit, a fault diagnosis method for the track circuit is proposed in this paper. First, a locomotive signal induced voltage model is established based on the transmission-line theory. Then, cases of the induced voltage envelope signals, when the track circuits are in the normal and fault conditions, respectively, are simulated. Next, a three-layer...
The track circuit electrical insulated joint faults will lead to the false acceptance of control information for trains and it will affect the safe operation of trains. In this paper the locomotive signal induced voltage model is established based on uniform transmission line theory and the amplitude envelopes of the induced voltage when the electrical insulated joint has malfunctioned are simulated...
In view of the lack of semantic information description in commonly-used knowledge representation modes such as framework and object-oriented mode, the domain ontology of electronic protective equipment fault diagnosis is designed by analyzing and summarizing the characteristics of the equipment fault cases. Considering that the traditional VSM (vector space model) ignores the role of the position...
