Monitoring system of continuous fractures trails with use of technology in the field of time reflectometry (TDR)

摘要

Monitoring system of continuous fractures trails with use of technology in the field of time reflectometry (TDR) refers to this patent to a continuous monitoring system to detect and identify, in real time, the occurrence of discontinuities mecu00e3nicas of Tracks, thereby minimizing the occurrence of failure, operational problems,The number of occurrences and time of restoration of the equipment, the occurrences with diagnoses were not identified and the events recurring maintenance, providing a fast, efficient and safe in real time.The system of continuous monitoring of fractures of tracks with the use of technology in the time domain reflectometry (TDR), is understood by the combination of two conductors (1) to establish a circuit in the device is used, a metal cable auxiliary (2), with length proportional The rail (7) and fixed near to this.This configuration makes the electromagnetic wave is confined in the circuit composed of trail and auxiliary cable (2). A signal generator (3) emits an electric pulse direct current, whose magnitude and frequency depend on the rail (7) to be monitored. This pulse is injected into the bar of trail and in the cable auxiliary (2) generating an electromagnetic wave in such media drivers.On the basis of these differences is established the signature in the time domain reflectometry (TDR) (4), by means of which the rail (7) is monitored. The information of the fault is generated by the system and presented in an alarm screen, which graphically displays (5) point estimated the problem and its characteristic.Information is also available for remote access, via a data network, function is supplemented by the interface (6) connecting to the system, which is also based on the signature of the reflectometry in the time domain to inform.
