Abstract

In mobile measuring apparatuses, the connections for the power supply or for battery charging and for data transfer are designed as plug connections. Said connections have the disadvantage that they easily become contaminated and wear out, which leads to frequent failures. In the new device, the connections are intended to be wear- free. This is achieved according to the invention by the connection for the power supply or for battery charging being produced by magnetic coupling and the connection for data transfer being produced by optical coupling. Mobile measuring apparatuses, especially workshop measuring apparatuses. <IMAGE>

Description

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

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.If these plug-in operations are often repeated in rough workshop operation, this leads to wear on the plug connections, which are accelerated by mechanical tolerances and contamination. 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 an object of the invention to provide a connection which is wear-free both for the power supply and for the data transfer.

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.In the prior art to date, methods are known in which wear-free connections for charging the battery are produced with the aid of magnetic coupling. There are also wear-free connections for data transfer, using inductive couplings such as optical transmission in the visible and infrared range.

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 of the wear-free power supply and the contactless 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 battery charging device should be of the type that one half of a cutting tape transformer is located in the stationary holder, while the other half is installed in the rear wall of the measuring device according to the figure. By suitable winding of the two halves of the ribbon transformer, a voltage conversion can also be achieved, which makes an additional 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 is realized with an optical coupling. For this purpose, one photodiode each as a transmitter and one phototransistor each as a receiver are arranged opposite each other in the measuring device and on the holder. In this way, a bidirectional data bus is formed, via which a main processor can now communicate with an auxiliary processor of a measuring device. There is also the possibility of transferring data from the measuring device to peripheral devices, such as, for. B. printer to output.
