FIELD: transportation.
SUBSTANCE: method includes requesting and receiving of diagnosis data from the onboard microprocessor locomotive control system in the form of equipment current technical condition parameters, statistical processing based on correlation analysis and formation of a warning signal in the event of equipment failure prediction. During statistical processing, the said diagnostic data are divided into groups relating to the same type of hardware assemblies. Correlation analysis was performed in each group for each parameter by correlation coefficients calculation. Equipment failure is predicted if the correlation coefficient differs from the average value by more than 2%. Technical diagnosing device includes means for connecting to the locomotive on-board microprocessor control system and a processing unit configured to implement the described method.
EFFECT: improved accuracy of failure prediction.
