Abstract

PURPOSE:To determine the degree of the faults in the pull-off of the trolley wire accurtely by using the displacement data by an optical method and the data sensed by a probing pin, compensating the data to the same measuring position, and computing the pull-off angle. CONSTITUTION:The probing pin 6 is provided on a boat body 5' in a fault sensor, and contacted with the pull-off 3. Thus operating positions d are sensed. The trolley wire 1 is scanned by laser light 8 by an optical displacement type measuring device 9. The displaced amount D is sensed by the time from a starting point ST to a pulse 1' which is caused by the reflected light. Said operating positions d and the displaced amount D are stored in a specified electric circuit. The displaced amount D corresponding to the positions where the probing pins 6 has been operated is read out by the address control of the distance pulse. The angle between the pull-off 3 and the boat body 5 is computed by the equation tan theta=height of probing pin h/(d-D). Thus the data is compensated to the same sensing position, and the degree of the fault can be determined highly accurately.
