Description

In Werkstätten findet man häufig mobile, akkubetriebene Meßgeräte, die zum Laden und zum Datentransfer in stationäre Wandhalterungen oder in Meßwagenhalterungen eingeschoben werden.Mobile, battery-operated are often found in workshops Measuring devices for charging and data transfer in stationary wall mounts or in measuring car mounts be inserted.

Werden diese Einschubvorgänge im rauhen Werkstattbetrieb oft wiederholt, so führt dies zur Abnutzung der Steckverbindungen, die durch mechanische Toleranzen und Verschmutzung noch beschleunigt werden. Die Folge sind häufige Ausfälle, die vermieden werden sollen.Are these insertion processes in rough workshop operation often repeated, this leads to wear of the Plug connections that are subject to mechanical tolerances and Pollution can still be accelerated. The result is frequent failures that should be avoided.

Deshalb ist es Aufgabe der Erfindung, eine Verbindung sowohl für die Stromversorgung als auch für den Datentransfer zu schaffen, die verschleißfrei ist. It is therefore the object of the invention to establish a connection both for the power supply and for the To create data transfer that is wear-free.  

Im bisherigen Stand der Technik sind Verfahren bekannt, bei denen verschleißfreie Verbindungen zum Akkuladen mit Hilfe magnetischer Kopplung hergestellt werden. Es existieren ebenfalls verschleißfreie Verbindungen zum Datentransfer, wobei hier induktive Kopplungen, wie optische Übertragung im sichtbaren und Infrarot-Bereich, benutzt werden.Methods are known in the prior art to date: where wear-free connections to battery charging with Magnetic coupling can be produced. It there are also wear-free connections to the Data transfer, with inductive couplings such as optical transmission in the visible and infrared range, to be used.

Der erfinderische Gedanke liegt nun in der Kombination der verschleißfreien Stromversorgung und dem berührungslosen Meßwert- oder Datentransfer.The inventive idea now lies in the combination the wear-free power supply and the non-contact measurement or data transfer.

Dabei soll die Stromversorgung bzw. die Vorrichtung zum Akkuladen von der Art sein, daß eine Hälfte eines Schnittbandtrafos sich in der stationären Halterung befindet, während die andere Hälfte in der Rückwand des Meßgerätes entsprechend der Figur eingebaut ist. Durch geeignete Bewicklung der beiden Hälften des Schnittbandtrafos kann außerdem noch eine Spannungswandlung erreicht werden, die einen zusätzlichen Transformator überflüssig macht.The power supply or the device for Battery charging of the type that one half of a Cut ribbon transformers in the stationary holder while the other half is in the back of the Measuring device is installed according to the figure. By suitable winding of the two halves of the Ribbon transformers can also be one Voltage conversion can be achieved, which is an additional Makes transformer unnecessary.

Der Datentransfer vom einzelnen Meßgerät zum Systembus und umgekehrt wird mit einer optischen Kopplung realisiert. Dazu werden im Meßgerät und an der Halterung jeweils gegenüber je eine Photodiode als Sender und je ein Phototransistor als Empfänger angeordnet. Auf diese Weise wird ein bidirektionaler Datenbus gebildet, über den jetzt ein Hauptprozessor mit einem Hilfsprozessor eines Meßgerätes kommunizieren kann. Es besteht auch die Möglichkeit, Daten vom Meßgerät an Peripheriegeräte, wie z. B. Drucker, auszugeben.The data transfer from the individual measuring device to the system bus and vice versa with an optical coupling realized. This is done in the measuring device and on the bracket each opposite a photodiode as a transmitter and each a phototransistor arranged as a receiver. To this A bidirectional data bus is formed via which is now a main processor with an auxiliary processor of a measuring device can communicate. There is also Possibility to transfer data from the measuring device to peripheral devices such as e.g. B. printer to output.
