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 insulation resistance of the cable

Measurement of voltage or current in power supply system

Measurement of counter and time

Measurement a current of switch moves

Discrete data acquisitionDiscrete data acquisition controllers are connected to lamps of electric centralization board or relay contacts of interlocking.

Numbers of checking discrete parameters: from 24 to 120Sampling 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

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 filterControllers 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.

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.

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 - 24Measuring 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.
