Device for automatically identifying catenary posts of a railway track to locate faults detected on the railway track
First Claim
1. Process for monitoring the condition of railroad tracks, of the type which consists of moving monitoring equipment on a railroad car (11) moving on said tracks (12a) and recording (21) the signals emitted by said monitoring equipment (14-17) gradually as said car moves forward, characterized in that it consists of pointing a radar (25a) on board said car towards characteristic structures (13) located along said tracks, recording (21) the corresponding echo signals simultaneously with said signals, to contribute to the subsequent identification of defects detected on said railroad tracks.
