During the XXII Olympics and XI Paralympic Games 2014 in Sochi 23 EMU-trains of ED4M series, equipped with an on-board monitoring system COMPACS®-EXPRESS-З, meant for real-time health monitoring of EMU-trains equipment and allows to detect the emergence and development of faults in time, displaying the information on the screen of the diagnostic controller in the form of messages of the expert system in the engineer`s cab, were operated in the following areas: Tuapse - Sochi, Sochi - Olympic Park, Sochi - Krasnaya Polyana, Sochi Airport. Also, all information about the bearing assemblies condition, pneumatic brake system and EMU-trains electric circuits in operation is generated and archived in the form of condition reports of each car and EMU-trains in general.
Thus, on the 8th of February, 2014, the on-board monitoring system COMPACS®-EXPRESS-3 revealed the late operation of the pressure regulator in the 043601 car on the ED4M-0436 EMU-train, information about this fault was displayed on the diagnostic controller screen in the form of expert system messages "CHECK_PR".
On the 26th of February, 2014, on the ED4M-0436 EMU-train the on-board monitoring system COMPACS®-EXPRESS-3 revealed, that the electrodynamic braking scheme hasn’t been assembled on motor cars 043606 and 043608, i.e. the braking substitution has occurred. This information was displayed on the diagnostic controller screen in the form of expert system messages "CHECK_POW_CIRC_EDB".
On the 4th of March, 2014, on the ED4M-0435 EMU-train the on-board monitoring system COMPACS®-EXPRESS-3 revealed an increased vibration level on the 1st and the 2nd wheel pairs on the left of the 043505 car, corresponding to the defect availability on the tread of the wheel pair tire. The information about this discrepancy was displayed on the diagnostic controller screen in the form of expert system messages "CHECK_WP".
The information about revealed failures is reported immediately to the personnel in charge.
According to the results of the operation, the on-board monitoring system confirmed its high efficiency, ensuring timely fault diagnosing with the issuing of recommendations, displayed on the diagnostic controller screen, to the service personnel, and thereby providing the improvement of safety and reliability of the transportation process, maintaining a high level of technical readiness of the rolling stock.
