Method and apparatus for detecting and tracing total cracks on track of the metropherone system

摘要

New concept of apparatus and associated method for the detection in near -real -time of total train train train train train train train train train train train train train train train train train train train train tracks using reflectiometry techniques, impedance marriages and electrical insulation with display for location and fault alarm, which allow implantation Air constant track monitoring using the time -reflection technique TDR (time domain reflectometry) for electrical signals, replacing track circuits that have been removed with the deployment of CBTC -type systems (communications -train based control),Using rails as transmission lines to better propagate the signal and to enable use in various metrophrea -rail systems, enabling signals generated to be propagated over longer distances, using signal filters and isolators and auxiliary apparatus Specifically involved to prevent the occurrence of false positives from occupation, current drainage, signal filtering and long -distance propagation, resulting in a robust and relatively inexpensive solution in relation to other projects already known for this purpose Nality.
