Abstract

Vorrichtung (1) zur Berechnung der Breite von heißem Asphalt, bestehend aus einem Temperaturscanner, einem Abstandssensor und einer Auswerteelektronik.Device (1) for calculating the width of hot asphalt, consisting of a temperature scanner, a distance sensor and an evaluation.

Description

Anwendungsgebiet:Field of use:

Die Erfindung betrifft ein Breitenmeßsystem zur Messung der Einbaubreite einer Asphaltschicht mittels eines Temperaturscanners.The invention relates to a width measuring system for measuring the paving width of an asphalt layer by means of a temperature scanner.

Stand der Technik:State of the art:

Werden Straßen neu gebaut oder repariert, so werden auf den Schotterunterbau mehrere Schichten von heißem Asphalt aufgebracht. Dies geschieht mit sogenannten Fertigern. Diese fahrbaren Maschinen besitzen Vorratsbehälter, Fördereinrichtungen und Ausbring- und Verdichtungssysteme. Der heiße Asphalt wird bei Temperaturen von 100 bis 150 Grad verteilt, auf die Straße gebracht und verdichtet.When roads are rebuilt or repaired, several layers of hot asphalt are applied to the ballast base. This happens with so-called pavers. These mobile machines have reservoirs, conveyors and discharge and compression systems. The hot asphalt is distributed at temperatures of 100 to 150 degrees, brought to the road and compacted.

Von MOBA wurde ein Gebrauchsmuster entwickelt, bei dem ein Temperaturscanner die heiße Asphaltschicht zeilenweise quer zur Fahrtrichtung abtastet und die Daten zur Beurteilung der Qualität verarbeitet und speichert.MOBA has developed a utility model in which a temperature scanner scans the hot asphalt layer line by line across the direction of travel and processes and stores the data to assess the quality.

Aufgabe dieses Gebrauchsmuster ist es, das System so weiterzuentwickeln, dass man damit über den Temperaturverlauf auch die Einbaubreite berechnen kann.The task of this utility model is to further develop the system in such a way that it is possible to calculate the installation width over the course of the temperature.

Lösung:Solution:

Der in Gebrauchsmuster 20.2009 016 129.3 beschriebene Temperaturscanner dient als Basis der Messung. Er scannt die heiße Asphaltschicht quer zur Fahrtrichtung ab und erkennt die seitlichen Kanten durch die Absenkung der Temperatur. Die jeweiligen Scanwinkel (links und rechts), bei denen die Temperatur um einen bestimmten Wert absinkt, werden als Breite erkannt und abgespeichert.The temperature scanner described in Utility Model 20.2009 016 129.3 serves as the basis of the measurement. He scans the hot asphalt layer transversely to the direction of travel and recognizes the lateral edges by lowering the temperature. The respective scan angles (left and right) at which the temperature drops by a certain value are recognized and stored as width.

Es wird nun die Höhe des Sensors über der Asphaltschicht bestimmt, um mit der Höhe und den Winkeln die Breite des Materials zu berechnen. Dies geschieht entweder manuell und anschließender Eingabe über Tastatur oder automatisch über eine zusätzliche Abstandsmessung. Zweckmäßigerweise kann dieser Sensor in den Scanner integriert werden, damit kann auch die Berechnung der Breite im Sensor selbst erfolgen. Es ist natürlich auch möglich einen separaten Abstandssensor zu verwenden und dem System den Abstandswert über geeignete Schnittstellen zur Verfügung zu stellen.Now the height of the sensor above the asphalt layer is determined in order to calculate the width of the material with the height and the angles. This is done either manually and subsequent input via keyboard or automatically via an additional distance measurement. Conveniently, this sensor can be integrated into the scanner, so that can also be done calculating the width in the sensor itself. Of course, it is also possible to use a separate distance sensor and to provide the system with the distance value via suitable interfaces.

1 zeigt schematisch den Aufbau eines solchen Systems. 1 schematically shows the structure of such a system.

Der Infrarotmeßstrahl bewegt sich zunächst von der Mitte nach links nach einer Seite. Nach Erkennen des Temperaturabfalles an der Kante von warm nach kalt speichert das System den dabei gemessenen Winkel α und schwenkt zurück. Das gleiche wiederholt sich auch an der gegenüberliegenden Seite, dort wird der Winkel β gespeichert, sodaß zu jedem Scan die beiden Grenzwinkel (α + β) ermittelt und abgespeichert sind (2).The Infrarotmeßstrahl moves first from the center to the left to one side. After detecting the temperature drop at the edge from warm to cold, the system stores the measured angle α and swings back. The same is repeated on the opposite side, where the angle β is stored, so that the two critical angles (α + β) are determined and stored for each scan ( 2 ).

Wird der Scanner senkrecht zu der zu vermessenden Fläche montiert, so ergibt sich aus der Addition tan α = Breite links/h und tan β = Breite rechts/h die Gesamtbreite der heißen Asphaltschicht.If the scanner is mounted perpendicular to the surface to be measured, then the total width of the hot asphalt layer results from the addition tan α = width left / h and tan β = width right / h.

Zur Höhenmessung kommen vorzugsweise Lasersensoren nach dem Prinzip der Lichtlaufzeitmessung zum Einsatz, es können jedoch auch Ultraschallsensoren oder andere Sensoren verwendet werden.For height measurement are preferably laser sensors according to the principle of light transit time measurement used, but it can also be used ultrasonic sensors or other sensors.
