Title: PROCEDURE FOR CONTROLLING A GUIDE SYSTEM OF A RAILWAY CONSTRUCTION MACHINE, ASSOCIATED METHOD AND ASSOCIATED GUIDE SYSTEM
Abstract:
In order to control a measuring system comprising a tacheometer (26) mounted on a carrier trolley (14) circulating on a railway track (12) under construction and a target (16) fastened to a railway construction machine (10), the carrier trolley (14) is circulated on the railway track (12) in a working direction (100) from a starting position to an arrival position in the vicinity of a topographic arrival singularity (58, 60); the carrier trolley (14) is immobilized and an observation (64, 70) of the topographic arrival singularity (58, 60) is made. Then, with the railway construction machine (10) having been brought into the starting position, an observation (66, 72) of the target (16) is made. Finally, the coordinates of the arrival position of the carrier trolley (14) are calculated as a function of the measurements made, of additional data relating to the starting position, and of positioning data of the topographic arrival singularity (58, 60) and data relating to a theoretical line of the track.
