At the time of XXII Olympic winter games in Sochi 23 EMU-trains of ED4M series, equipped with the on-board monitoring system COMPACS®-EXPRESS-З were operated in the following areas: Tuapse - Sochi, Sochi - Olympic Park, Sochi Airport. During this time the system has proved itself as a reliable and effective instrument, allowing to reliably track changes of the most important assemblies and EMU-trains units health in real time: assemblies of mechanical part (bearings of axle assemblies and traction electric engines, reducer gear, coupling, wheel pair tread), electrical equipment of power and auxiliary circuits (traction electric motors, groups of pre-braking resistors, transducer, generators, compressors and others), compressed-air braking system equipment, control circuits of the traction and auxiliary electrical equipment.
Thus, on the 19th of February, 2014, the on-board system for monitoring COMPACS®-EXPRESS-3 revealed the failure of transducer on the 044007 car of ED4M-0440 train, the information about which was displayed on the screen of the diagnostic controller in the form of expert system messages "CHECK_ TRANSDUCER_CIRCUIT (BREAKAGE)".
On the 19th of February 2014, on the ED4M-0440 train the on-board system for monitoring COMPACS®-EXPRESS-3 revealed the increased level of vibration at the first wheel pair of the 044001car, which corresponds to the defect occurrence on the tread of the wheel pair tire, the information about this defect was displayed on the screen of the diagnostic controller in the form of expert system messages "CHECK_WP".
On-board monitoring systems are a reliable source of information about the rolling stock equipment condition and means of ensuring the safety of suburban passenger services on the North-Caucasian railway.
