This paper describes system for diagnostics of passing vehicles with help of measurements carried out at the track. There are the signals of vibration measured on rail foot and noise signals measured near to underside of vehicle. Further failures which could be measured by this method and estimation of their dominant frequencies are described too. The system has been tested on vehicles in metro and several methods of evaluation have been proposed. Signals are assessed in the time domain and in the frequency domain. Evaluation of results is carried out using neural networks. |

Tento článek popisuje systém pro diagnostiku projíždějících vozidel pomocí měření prováděných na trati. Jsou měřeny signály vibrací na patě kolejnice a hluk v blízkosti spodní části vozidla. Poruchy, které by mohly být pomocí této metody detekovány a odhad jejich dominantních frekvencí jsou popsány také. Tento systém byl testován na vozidlech v metru a bylo navrženo několik metod hodnocení. Signály jsou vyhodnocovány v časové oblasti a ve frekvenční oblasti. Vyhodnocení výsledků se provádí také pomocí neuronových sítí. |
