Diesel loco event recorder RPDA-T, RPDA-TM

Event recorders RPDA-T, RPDA-TM are designed for automatic measurement, recording and processing of data about the movement and the operation of the locomotive; the goal is to control and registration work data and fuel consumption, to control the technical condition of shunting locomotives series ChME3, TEM2, TEM7A, TEM9H, TEM9TA, TEM14, TEM18DM, and main-line locomotives 2TE10, TEP70, M62, 2TE116, 2ТE25К2M. System can be easily adjusted to other locomotive series.

So far in locomotive depot records of fuel consumption was based on data to be entered by drives during locomotive operation. Fuel volume was measured by driver or special operator as the visual difference between the marks of fuel in the fuel tank on a special measurement line at the beginning and end of work, and the charge was determined by weight, based on the fuel volume, and density of fuel, which is set out in servicing depots. Accuracy of such measurements is rather pure and it is not possible to lead accurate records of the fuel consumption and to monitor its use.

Operation features of RPDA-T, RPDA-TM system

Event recorder RPDA-T, RPDA-TM is data acquisition system. All measured data, including fuel consumption and locomotive operation data, can be record on a special flash-drive, named “RPDA cartridge”, and also can be send via GSM/GPRS channel.

Special software (workplace) is used for decoding recorded data from cartridge.

Decoded data is a basis for future analysis:

1. Fuel consumption and locomotive operation data

  • the amount of fuel (volume, mass),
  • the estimated value of fuel consumption of diesel for a change,
  • fuel consumption for non-driving operations,
  • the time of the locomotive is under load and at idle,
  • idle time of the locomotive ,
  • speed and passed way of locomotive.

2. Technical condition state of the locomotive. 

3. Summary of the use of locomotives. 

4. Summary of engine drivers work.

Application effect components:

  • Reduction of up to 5% of fuel consumption and up to 2% of diesel oil;

  • Prevention of fuel stealing;

  • Increasing the accuracy of planning and consideration of fuel consumption;

  • Reduction of labor costs for the analysis of fuel consumption.

  • Enhancement of the quality of locomotive service based on analysis of recorded parameters, decrypted and obtained by special workplace.

  • Distribution of shunting locomotives for areas to optimize the operating modes in accordance with their actual technical condition in order to reduce fuel consumption.

  • Reduction of the harmful effects on the environment by lowering the emissions of harmful gases into the atmosphere.
