The first experimental on-board system for condition monitoring COMPACS®-EXPRESS-З was commissioned in the train depot Ramenskoye of Moskow Railways, on the train of ED4M-0133 series in 2009. The system conducts real-time condition monitoring of the following EMU-train units: axle equipment, traction electric motors, compressor, transducer, compressed-air braking system, and allows timely detect ion of the malfunctions appearance and developing, displaying the information on the diagnostic controller in the driver’s cabin in the form of an expert system’s message. Also, all the information on the bearing assemblies, compressed-air brake system and electric circuits of the train in operation forms and archives in a form of condition reports for each car and the whole train and is automatically transmitted to the Compacs-Net® diagnostic network server in the depot.
Currently, on-board monitoring system, allowing to control the condition of the depot electric multiple unit stock and timely detect the causes of malfunctions, to carry out condition-monitored prevention of defects in train functioning , are equipping EMU-trains of ED4M-0022, 0026, 0048, 0352, 0353 and 0462 series. The COMPACS®- EXPRESS-3 on-board monitoring system in complex with the COMPACS®-EXPRESS-TR1 and the COMPACS®-EXPRESS-TR3 stationary diagnostic systems is a part of the ACS SMSRTM™ EMU COMPACS® - automatic control system of safe-money-saving operation and repair of EMU-train machinery, which main efficiency matters are:
- increase of EMU-train run-to-failure period and interval between repairs of the machinery;
- decrease of the EMU-train machinery failures and reduction of emergency and downtime losses;
- decrease of the EMU-train and its equipment repair duration and consumption of materials.
The on-board system for condition monitoring COMPACS®-EXPRESS-3 became an important element of modern railway transport for providing safety of its operation.
Thus, on 14.07.2014 during the commissioning of ED4M-0462 train, the COMPACS®-EXPRESS-3 on-board monitoring system detected the late response of the pressure regulator in the cars 046201 and 046209, issuing the information on the diagnostic controller display in the form of an expert system message "CHECK_PR, PM".
