Mobile transponder reader

Abstract

The invention relates to a mobile reader (1) for reading out information from a transponder (10). Said mobile reader comprises a first transmitter / receiver device (2) for emitting a read-out signal to a transponder (10) and for receiving a response signal emitted by the transformer (10) in response to the read-out signal, wherein said response signal comprises identification information for identifying the transponder (10). The first transmitter / receiver device (2) functions with wireless communication on the basis of electromagnetic waves in a first frequency range. The mobile reader (1) further comprises a second transmitter / receiver device (3) for the wireless communication with a base station on the basis of electromagnetic waves in a second frequency range. The second transmitter / receiver device (3) transmits the identification information received by the first transmitter / receiver device in the response signal to the base station.

Description

technical field [0001] The invention relates to a mobile reading device for reading information from a transponder. Background technique [0002] Transponders are passive components used to identify objects and / or goods during handling and / or transport. In any case, the transponder can be mounted on the object itself or on the container containing the object. Information that can be read by a suitable transponder reading device is stored or contained within the transponder. In this case, usually one transponder is firmly mounted on each container and / or each object. For example, in the manufacture of silicon wafers which are transported in plastic containers, the relevant transponders can be soldered to the relevant plastic container or mounted in corresponding holders. The transponder reading device is arranged in a fixed manner in the transport and / or processing station along the transport and / or processing chain of the objects. These fixed transponder reading devices ...

AI Technical Summary

Problems solved by technology

[0005] A disadvantage of the above-mentioned systems for controlling and monitoring the transportation and / or processing of objects by means of transponders mounted on the objects and fixed transponder reading devices is that when objects or containers containing objects are removed from a processing and and / or when the transport station transmits to the next station, the information contained in these individual transponders cannot be accessed

Having fixed transponder reading devices at each storage location would be too resource intensive and expensive

Therefore, these known systems cannot readily identify objects carrying transponders, nor can they seek and locate lost objects
