Abstract

Measuring and indicating load support distribution using several measurements arranged at the support surface of vehicle or aircraft. The method for measuring and indicating of the load support distribution of load support and transporting, esp. with vehicles and aircraft is carried out, by measuring, storage and the evaluation of the pressures and the pressure alterations, which produce the supported load (Nett) on the support surface or the introduction of the loaded wt. plus the vehicle or the aeroplane wt. (gross) on the ground. Several measuring systems are applied at the supporting surface, at the vehicle or the plane, carry out the point measuring of the wt. distribution of the total or loaded wt. and its alterations. The values of the individual measuring systems are prepared in an electronic circuit and are evaluated in a computer programme, stored and are indicated on a display or recorded by a printer, in a virtual, observable from all sides, three dimensional representative form of the loaded wt. distribution.

Description

Verfahren zur Messung der Ladelast von Lagerflächen, z. B. Paletten oder Fahrzeu­ gen sind bekannt. Sie dienen einer schnellen on-line-Erfassung des Ladegewichtes während der Be- und Entladung. Hierzu werden verschiedene Methoden angewen­ det. So z. B. die Druckmessung der Hydraulikflüssigkeiten von Hubzylindern, Stoß­ dämpfern, etc. . Die Meßwerte werden an mehreren Stellen erfaßt und gemeinsam ausgewertet. Dieses Prinzip beruht auf dem Verfahren der Gewichtsmessung von allgemeinen Handelswaagen.Method for measuring the loading load of storage areas, e.g. B. pallets or vehicles gene are known. They are used for a quick online recording of the loading weight during loading and unloading. Various methods are used for this det. So z. B. the pressure measurement of the hydraulic fluids of lifting cylinders, shock dampers, etc.. The measured values are recorded at several points and together evaluated. This principle is based on the method of weight measurement by general commercial scales.

Nachteilig bei derlei Systemen ist, daß nur auf das Gesamtgewicht geschlossen wer­ den kann. Ferner besteht natürlich die Möglichkeit die Ladelast zu schätzen oder auf einer entsprechenden Großwaage zu messen.A disadvantage of such systems is that only the total weight is concluded that can. Furthermore, there is of course the possibility to estimate the load or on an appropriate large scale to measure.

Es kommt aber oft vor, daß die Verteilung der Ladelast auf der Lagerfläche oder im Fahrzeug von besonderer Bedeutung ist. Bei Straßenfahrzeugen z. B. ist die jeweils zulässige Achslast von Bedeutung für die Betriebs- und Fahrsicherheit.But it often happens that the distribution of the load on the storage area or in Vehicle is of particular importance. In road vehicles such. B. is each permissible axle load important for operational and driving safety.

Bei Flugzeugen ist die genaue Kenntnis der Ladelastverteilung ebenfalls von großer Bedeutung für die Flugsicherheit, für die optimale Beladung und der daraus sich er­ gebenden wirtschaftlichen Nutzung.In the case of aircraft, precise knowledge of the load distribution is also of great importance Significance for flight safety, for the optimal loading and the result giving economic use.

Die Erfindung hat sich die Aufgabe gestellt, die Ladelastverteilung exakt zu erfassen, einem angeschlossenen Rechner zur Verarbeitung und Auswertung zu übermitteln sowie dem Verantwortlichen als dreidimensionales Bild zur Verfügung zu steilen.The object of the invention is to record the load distribution precisely, to be sent to a connected computer for processing and evaluation as well as to be available to the person responsible as a three-dimensional image.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß an der zu messenden La­ gerfläche, dem Fahrzeug oder Flugzeug an mehrere Stellen Vorrichtungen zur Er­ fassung von Gewichten angeordnet sind. Dies können Kraftsensoren, Dehnungs­ meßstreifen, Drucksensoren in der Hydraulik oder für den Reifendruck sein. Weiter­ hin ist vorgesehen, die Eintauchtiefe von Federn oder Stoßdämpfern zu nutzen. An Bauteilen mit lastabhängiger Durchbiegung sind Dehnungsmeßstreifen anzubringen. Die damit erfaßten Einzelwerte werden in einer geeigneten elektronischen Schaltung aufbereitet und mittels Draht, Funk oder Licht an einen Rechner übertragen. Ein geeignetes Rechnerprogramm wertet die Daten aus und zeigt sie auf einem Dis­ play in dreidimensionaler Form an. Hierdurch entsteht ein dreidimensionales, deutli­ ches und plastisches Abbild der Ladelastverteilung. Durch virtuelles Drehen auf dem Display wird dieses Abbild von allen Seiten betrachtet. Natürlich kann aus den Ein­ zeldaten das Gesamtgewicht errechnet und außerdem eine während des Betriebes auftretende Verschiebung der Ladelast festgestellt werden.According to the invention the object is achieved in that the La surface, the vehicle or aircraft in several places setting of weights are arranged. This can be force sensors, strain measuring strips, pressure sensors in hydraulics or for tire pressure. Next There is provision to use the immersion depth of springs or shock absorbers. On Strain gauges must be attached to components with load-dependent deflection. The individual values recorded in this way are stored in a suitable electronic circuit processed and transmitted to a computer using wire, radio or light. A suitable computer program evaluates the data and shows it on a disc play in three-dimensional form. This creates a three-dimensional, clear ch and plastic image of the load distribution. By virtual turning on the This image is viewed from all sides on the display. Of course, from the one the total weight and also one during operation occurring shift of the load can be determined.
