Abstract

Locomotive safety controlling system is a system currently used in railway locomotives. The system detects and acquires useful parameters, analyzes the data, gives right decision according to the results and saves information for future use. As three of the important functions, compression, storage and analysis of voice data have shown to b e extremely useful. The analysis process shows that joint time-frequency extraction is effective when restoring voice from the unclear data. Not only does the SNR of the reconstructed signal improve greatly, most components of some random noise severely blurred voice signal can be removed as well. Description of system scheme and data analysis is included in the paper.
