Diagnostic unit of reception coils

Diagnostic unit of reception coils & locomotive automatic signaling system receiver (MD-ALSN) is designed for automatic testing of reception coils KPU-1 and KPU-2 and for functional check of ALSN signals receipt by on-board interval control and safety systems without fixed circuit.

MD-ALSN will ensure:

  • Automatic monitoring of the following parameters of reception coils:
  • Inductance;
  • Quality factor;
  • Active resistance;
  • Automatic monitoring of reception coils open circuits and short circuits;
  • Automatic monitoring of ALSN receiver functioning at carrier frequencies of 25 Hz, 50 Hz and 75 Hz;
  • Recording of locomotive ALSN receiving equipment check results into the nonvolatile memory;
  • Transfer of check data via radio channel;
  • CAN & RS-485 interfaces to connect with other systems.

Realized projects:

  • MD-ALSN unit is installed on TEЗЗА and TEPЗЗА locomotive series in Kazakhstan. During 2016-2017 more than 130 locomotives in Kazakhstan were equipped by MD-ALSN. Later on, it is planned to equip all the operating locomotives of Kazakhstan by MD-ALSN unit.
