About APK-DK (STDM)
The computerized diagnostic system of dispatch control APK-DK (STDM) is
developed by LLC “KIT” is intended for technical diagnostics of railway
automatic equipment, optimization of maintenance process and the function
of controlling the information flow to the passengers. The system is realized
as a multilevel hardware and software complex for the collection, storage,
analysis, and reporting on data. Collection of diagnostic information from
multiple systems and signaling equipment is performed using controllers of
our own development, compatible with all modern Russian and European
systems. Storage and data processing occurs on selected data-centers or in
the Cloud. Access to data is provided via client-server technology and using
mobile devices.
Development of APK-DK (STDM) is being conducted since 1995 in Russia, St.
Petersburg. As of now, the system has been installed on more than 3000
stations and stages in Russia.

Measurement of voltage in the tonal track circuits
(TRC) in the frequencies range from 420 to 5555 Hh
Measurement of insulation resistance of
the cable
Measurement of voltage or current in
power supply system
Measurement of counter

current of switch
moves
Discrete data acquisition
Discrete data acquisition controllers are connected to lamps of electric centralization board or relay
contacts of interlocking.
Numbers of checking discrete parameters: from 24 to 120
Sampling time: 10 times per second
The couplings used in our system make it compatible with the systems currently used on the railway
stations (e.g. Microprocessor centralization MPC, Relay-processor centralization RPC, systems of
centralized traffic control CTC). Therefore, no additional mounting is required.
Voltage and insulation resistance measurement in the track circuits
One controller determines three parameters in each of eight railway circuits: voltage, phase shift and insulation
resistance of cable conductors according ground. In addition the frequency of data acquisition is 1 per second.
In the tonal track circuits (TRC) we perform the voltage
measurement in four points:
- Out of track generator
- Entrance of track receiver
- On the relay coil
- Out of track filter
Controllers are situated on the relay rack of electric
centralized offices, electric centralized modules and
automatic block system based on TRC modules.
Sampling time of controller is once per two seconds.
Insulation resistance measurement
Following insulation resistance measurements are
realized in the APK-DK(STDM) system:
- insulation resistance of cable conductors
relative to the ground (24 galvanic uncoupled
chains);
- insulation resistance of 24 galvanic uncoupled
chains relative to each other in all combinations.
Numbers of measuring channels - 24
Measuring frequency: from 1 до 60 seconds
Controller provides the insulation resistance measurement in the range from 0.1 to 100 Mohm.
Safe connection to control chains is achieved using galvanic isolations of measuring channels among
themselves. Insulation voltage is at least 2000V.
Using AKSI-24 controller in the APK-DK (STDM) system provides uninterrupted and complex control of cable
conductors conditions.
Current and voltage measurement
Current and voltage measurement in power supply system and switches is
done by connecting to existing shunts.
The cycle of measurements is up to 50 times per second.
Plot of DC switch moves
Voltages of power supply
Algorithms for graph analysis
We have developed algorithms for the graph analysis of currents of DC switch
moves to identify violations in the performance of switches.
Supervision of the Power Supply Systems
