Methods of EMU-train electropneumatic systems diagnostics

Print

The diagnostics of the electropneumatic system realizes the principle of unit-by-unit diagnostics with the maximal involving of regular equipment of the electric unit: compressors, control transformer, control circuit devices and manual control parts which provide autonomy from outer air-supplying sources and high automation of diagnostics process.

In the process of the electropneumatic system diagnostics of electric train section the COMPACS®-EXPRESS-TR3 system carries out an automatic control of the testing process, including: the power and control of electric circuits and pneumatic system of electric train section; management of gasdynamic processes in a pneumatic brake network, imitating different modes of equipment operation; passing the control signals into the power and auxiliary electric circuits.

The system determines quantitative characteristics of the physical values used as informative diagnostic signs: tension, current, pure resistance, pressure, time intervals, amount and duration of the impulses repetition and displays them in the monitor in a special panel. An embedded automatic expert system, in accordance with the programmed rules, issues goal indicating prescriptions on the screen to the personnel on the further actions in the form of text (expert) messages and presents the diagnostic signs on the basis of the icons colored according to the equipment state danger level.
