摘要:
A system is disclosed for monitoring condition of a railways installation such as a points machine. The system includes a plurality of sensors (S 1 , S 2 , S 3 -S N ) associated with elements of the installation for monitoring parameters indicative of operating capability of the installation. The system includes means ( 12, 23 ) for processing the monitored parameters to determine whether the parameters are changing relative to reference values and to determine whether the changes are indicative of an increased risk of malfunction in the installation. The processing means may include a digital computer programmed with condition monitoring and fault detection software. A method of monitoring condition of a railways installation is also disclosed.

Die Erfindung betrifft ein Verfahren zur Optimierung der Gleisoberbauinstandhaltung mit den Schritten Identifizieren (501) von im Gleis vorkommenden und bei Gleisvermessungen hervortretenden Einzelfehlertypen, Ermitteln (501) von Referenzmessungen für jeden dieser Einzelfehlertypen, Anlegen (501) von Datensätzen bestehend aus jeweils einer Referenzmessung in Form eines Messdatenvektors sowie deren zugeordneter Einzelfehlertyp in einer Datenbank (502) für bekannte Einzelfehlertypen, Trainieren eines Klassifikators (505) mit den angelegten Datensätzen, Klassifizieren von neuen Messdaten (503, 504) eines Einzelfehlers anhand der angelegten Datensätze durch den Klassifikator (505) und Entscheiden (506) über Instandhaltungsmaßnahmen bezogen auf den Einzelfehler zumindest teilweise basierend auf der Klassifizierung der Messdaten (503, 504) des Einzelfehlers. Die Erfindung bezieht sich ferner auf eine entsprechende Datenbank (502) zur Optimierung der Gleisoberbauinstandhaltung.
摘要:
The present invention relates to conditions monitoring of structures forming part of a transport network, e.g. structural health monitoring of structures, especially tunnels by performing distributed acoustic sensing (DAS) on at least one optical fiber (104) deployed so as to monitor the structure (206) and detecting and analyzing the acoustic response to movement of traffic (205) on the network in the vicinity of the structure to detect the acoustic response (303, 304) of the structure. The acoustic response of the structure is then analyzed to detect any change in condition.

摘要:
The invention is concerned with the renewal and maintenance system TRIS® running on a computer having a database containing relevant data about a railway track and being programmed to calculate from said data, by applying load related parameters based on maximum allowed train speed, maximum allowed axle load and cumulative passing weight during the time span of interest, a time related quality-figure, wherein said calculation is based on dynamic calculation models to calculate a maintenance strategy according to which maintenance can be carried out such that said track meets the prescribed standards for a predetermined time span.
摘要:
An aerial system control network for an unmanned aerial vehicle for inspecting railroad assets comprising a ground control system configured to transmit a flight plan including a rail system and a flight path to the unmanned aerial vehicle, detect an interference along the flight path and adjust the flight plan based on the interference, wherein the received data includes a plurality of images captured from at least one camera mounted on the unmanned aerial vehicle, wherein the ground control system is further configured to monitor the plurality of images for a faulty condition of the rail system, and wherein the faulty condition is identified from a difference in a first image and a second image taken along the flight path.
