ZPW-2000A track circuit transmitter and receiver fault diagnosis method

Abstract

The invention discloses a ZPW-2000A track circuit transmitter and receiver fault diagnosis method. The method comprises the following steps: S1, acquiring sound data of track circuit transmitter equipment and track circuit receiver equipment in various states; S2, performing feature extraction on the sound data in each state through Mel-frequency cepstral coefficient or wavelet packet analysis to obtain a corresponding feature matrix in each state; S3, constructing a corresponding data set based on the feature matrix in each state; and S4, carrying out random forest training and classification on the data set corresponding to each state to obtain a data classification result, and obtaining an analysis result of each fault type based on the data classification result. According to the invention, a data acquisition mode is set as a recording mode, and the method has the advantages of non-contact measurement and high safety. In addition, a ZPW-2000A track circuit transmitter and receiver fault diagnosis method based on a machine learning algorithm is adopted, the defects that according to a traditional detection method, maintainers need to have rich experience, and the maintenance process is complex are overcome, and the maintenance efficiency is improved.

Description
