Description

"Codeträger, durch Entfernungsmessung zu lesen" "Code carrier, read by distance measurement"

Es ist bekannt, Information z.B. als Code im Transportwesen zu speichern. Zum Lesen des Codes bedient man sich verschiedener physikalischer Verfahren, auf die die Codeausbildung Rücksicht nimmt. Dieser Codeträger kann z.B. auf dem Transportgut, auf dem Transportmittel oder dem Lagermittel aufgebracht sein und an verschiedenen Orten zu verschiedenen Zeiten abgefragt werden.It is known to store information e.g. as code in transport. Various physical methods are used to read the code that takes code training into account. This code carrier can e.g. on the transported goods, be applied to the means of transport or the storage means and on various Locations can be queried at different times.

So sind verschiedene Verfahren bekannt bzw. vorstellbar, die auf folgenden Prinzipien beruhen: den mechanischen, elektrischen, akustischen, pneumatischen, hydraulischen, chemischen, magnetischen und elektromagnetischen, optischen und radioaktiven.Various methods are known or conceivable which are based on the following Principles: the mechanical, electrical, acoustic, pneumatic, hydraulic, chemical, magnetic and electromagnetic, optical and radioactive.

Bei den bekannten, berührungslos arbeitenden Verfahren werden Reflexions-/Remissions- oder Transmissionsprinzipien benutzt.In the known, non-contact methods, reflection / remission or transmission principles are used.

Auch sind Verfahren bekannt, die die Entfernungsunterschiede durch Interferenzverstimmung erkennen. Hierbei müssen jedoch die Abstände Leser - Code genau eingehalten werden. Diese Verfahren haben jedoch den Mangel, daß sie nur durch ein physikalisches Prinzip erkannt werden können. Die Zuverlässigkeit leidet darunter.Methods are also known, which by means of the differences in distance Detect interference detuning. Here, however, the distances between the reader and the code are strictly adhered to. However, these methods have the defect that they can only go through a physical principle can be recognized. Reliability suffers as a result.

Erfindungsgemäß wird das dadurch vermieden, daß der Code als erhabene und vertiefende Oberflächen gebildet (Fig. 1-3) und vor den Abfragegeräten A und B im Abstand a vorbeigeführt wird cit.1).According to the invention this is avoided in that the code as a raised and recessed surfaces are formed (Figs. 1-3) and in front of the interrogators A and B is passed at a distance a cit.1).

Dabei kann der Abstand a jeweils unterschiedlich sein, da erfindungsgemäß nur die Höhendifferenz Ah zum Basisniveau zur Codierung benutzt wird. Die Abfragegeräte A und B können dabei nach verschiedenen physikalischen Prinzipien a@@eiten, wie z.B. optisch/Station A und akustlsch/Station B (Laser und Ultraschall) Diese Abfragegeräte können beim Lesevorgang geschwenkt oder oszillierend bewegt werden, um den Code mehrmals zu lesen.The distance a can be different in each case, since according to the invention only the height difference Ah to the base level is used for coding. The interrogators A and B can follow different physical principles a @@ eiten, such as optical / station A and acoustic / station B (laser and ultrasound) These interrogation devices can be swiveled or moved in an oscillating manner during the reading process to read the code multiple times.
