Saint Petersburg-Moscow EMU-train depot already more than two years uses electric trains, which are equipped with on-board monitoring system COMPACS®-EXPRESS-3.
The systems are fully off-line and don`t require the involvement of additional staff, as well as the application of special knowledge and skills by the locomotive crews and maintenance personnel for getting information about the condition of rolling stock units. All data on the condition, obtained on the basis of measuring system, are transmitted to the server of the depot diagnostic network Compacs-Net® by the atmospheric communication link. After that the data become available to the personnel in charge for diagnostics and heads of depot.
During the operation of on-board systems COMPACS®-EXPRESS-3 the failures of traction electric equipment, equipment of auxiliary circuits and pneumatic train systems and also equipment of mechanical parts were detected. Thereby, in autumn 2012 by usage of the system instructions the preventive repair of two traction motors electric ED4M-0376 and two traction motors electric ED4M-0381was carried out in time. Timely preventive repair gave tangible economic effect just as on the depot, because the repair was carried out at the expense of the manufacturer, so on suburban complex in general, due to the exclusion of mobile units sudden failure and the risk, associated with damage of uninterruptedness and the safety of the transport operation.
On-board systems COMPACS®-EXPRESS-3 in cooperation with the diagnostic network of depot Compacs-Net® is an effective and indispensable mean to maintain the proper level of operational readiness and ensure safety and continuity of the suburban electric trains movement.
