PROCEDE ET SYSTEME DE DETECTION D'IMPACTS SUR DES ZONES A SURVEILLER D'UN VEHICULE ROULANT

摘要

The method involves placing vibration sensors (11a-11d) in direct contact with monitoring zones e.g. maintenance plates (21a-21c), of floor (21) of a rolling vehicle i.e. railway vehicle (2), and analyzing vibration signals from the vibration sensors for detecting impacts on the monitoring zones of the rolling vehicle. Impact coefficient for each vibration signal provided by the sensors is measured. The impact coefficient is compared with a predetermined threshold value. Impact detection messages are emitted when the impact coefficient exceeds the predetermined threshold value. An independent claim is also included for a system for detection of impacts on monitoring zone of a rolling vehicle.
