Patent ID: 7084755

Claim:
Method for monitoring the region ( 1 , 7 ) of technical rolling bodies ( 7 ), in particular their support ( 1 ) such as rails of the wheel rail systems or bearings, by employing of converters ( 2 , 3 , 4 , 8 ) which are disposed at the support ( 1 ) or at the rolling bodies ( 7 ), which converters ( 2 , 3 , 4 , 8 ) capture forces occurring in the support ( 1 ) or at the rolling body ( 7 ), wherein the converters ( 2 , 3 , 4 , 8 ) generate electrical pulses and signalize the electrical pulses to an electrical control and evaluation station ( 6 ), wherein changes in state of the monitored region, such as material damages or separating damages, are detected by way of the electrical pulses, characterized in that at least one of the electrical converters ( 2 , 3 , 4 , 8 ) disposed at the support ( 1 ) in the monitored region ( 1 , 7 ) of the technical rolling body ( 7 ) or at least at the technical rolling body ( 7 ) is subjected actively with electrical energy ( 5 a , 9 ) and thereby the converter ( 2 , 3 , 4 , 8 ) feeds evaluable pulses ( 5 a′ , 5 b , 5 c′ ) into the support ( 1 ) or the rolling body ( 7 ), which pulses ( 5 a′ , 5 b , 5 c′ ) are captured by at least one of the converters ( 2 , 3 , 4 , 8 ), wherein pulses ( 5 a′ , 5 b , 5 c′ ) in turn are emitted by at least one of the converters ( 2 , 3 , 4 , 8 ), which pulses are captured by the control and evaluation device ( 6 ) as evaluable pulses ( 5 c , 9 ′), and whereby the region ( 1 , 7 ) of the technical rolling bodies ( 7 ) is monitored at any time relative to changes in state.
