Computerized research car for monitoring of the overhead system, automatics and communications KVL-ARKS (KVL-E.2, KVL-Sh)

KVL-ARKS (conformance certificate number is: ССФЖТ RU.ЦП05.Б.06497) is a part of diagnostic complex “ERA”. KVL-ARKS can operate both as a part of complex, and independently, on a separate schedule.

KVL-ARKS is designed for complex automated monitoring of the technical parameters of the overhead system, technological parameters of the floor units automatic system, and, also, parameters of the technical train radio communication means at the real-time in compliance with requirements of the OJSC RZD current regulations for the regulated purpose parameters.

On the basis of KVL-ARKS produced specialized research cars: KVL-E.2 for the control of condition of the overhead contact system and KVL-Sh for the control of the automatics and telemechanics systems.

KVL-ARKS on-board equipment includes:

1. Automated overhead on-board testing system from computerized track-test car (BAS KVL-E.2).

2. Monitoring and diagnostic systems for conditions of track devices in railway automatics and track circuits.

3. Monitoring system for radio communication parameters.

For the electric power of KVL-ARKS control systems has a separate power supply system SES.

The design of systems and sensors that are placed inside, outside the wagon body, and on the elements of bogie, ensures their protection from the environment: moisture, dust, small mechanical particles and atmospheric precipitation.

KVL-ARKS control systems provided the methods and means of testing and calibration.

Distinctive characteristics:

  • The software runs under Windows operating system and has a user-friendly interface.
  • BAS KVL-E.2 allows before the detour to form the route of upcoming detour as scheme-graphical image with the ability to monitor in real time the current position of the track-test car.
  • Display of real-time location of track-test car in the scheme of railways with reference to the geodesic (GLONASS/GPS) and railway coordinates with automatic identification of moving direction on the switches.
  • Fixing system for supports not only allows to register the presence of supports of overhead contact system, but also to measure their distance from the track axle.
  • Use of measuring runner with non-contact sensors provides a high reliability of the results in terms of actual interaction of the overhead catenary with power collector and independent measurements of weather conditions.
  • After the detour of section of the overhead contact system the representative of railway division receives a report about passage results from this section in the form of graphs and summary tables of detected abnormalities in both paper and electronic form.
  • Allows for post-processing results of a survey in the track-test car directly during the detour as information becomes available about the state of the overhead contact system.
  • Video observation system has high resolution and allows in post-processing mode to view the image of the overhead contact system in areas of identified parameters deviations.
  • Duplicate monitors in the observation tower allow to control the detour results in real time rapidly.
  • The principles embodied in the structure of onboard automated system (BAS) KVL-E.2 can expand its functionality as by increasing and improving the sensor equipment and information processing tools, and by implementing new techniques using a basic set of hardware.
