Safe resource-saving operation of motor driven rolling stock (MDRS) based on real-time condition monitoring

Print

In the second half of the 90s a variety of diagnostic units, not being linked to a single technological network and having some significant disadvantages, appeared on the railway system:

  • Subjectivity, i.e. complete dependence of the diagnostic results from the diagnostician.

  • High labor intensity and long-drawn diagnosis, due to the low degree of automation of the diagnostic process, which does not provide comprehensive diagnosis.

  • Low reliability of the results due to above mentioned reasons, generating position error as well as dynamic error connected with comparability of the diagnostic period with an interval of errors till critical value.

  • Unavailability of objective information about technical state of motor driven rolling stock and its units in real time, i.e. pure observability of true condition of motor driven rolling stock.

The implementation of system COMPACS® will realize condition-monitored maintenance of motor driven rolling stock with automatic term planning and volume of works for maintenance and repair only those components and assemblies of MDRS which really need to be repaired. In this case the volume of schedule-based repairs TR-1 TR-2 TR-3 reduced. Real-time condition monitoring increases greatly serviceability ratio of rolling stock. If now it is 0.92, after the implementation of radically new technology of equipment operation, based on knowledge of the technical state of the equipment at any time, it will raise up to 0,96-0,98. This means the reduction of operating expenses of repair downtime in 3-4 times (60-80%) and operation of 15-20 trains of ten cars each without the purchase of new rolling stock.
