Abstract
The invention relates to a detection apparatus, in particular a code reader, comprising an identification unit for identifying an object transported by a conveying device, in particular a continuous conveyor, further in particular a roller conveyor, characterized in that the detection apparatus has at least a first microphone and is configured to detect the object acoustically, in particular during transport, by means of at least the first microphone, and to initiate an identification process of the object by means of the identification unit only when the object is detected.
Claims30
A detection apparatus, comprising an identification unit for identifying an object transported by a conveying device,
- wherein the detection apparatus has at least a first microphone and is configured to detect the object acoustically, in particular during transport, by means of at least the first microphone, and to initiate an identification process of the object by means of the identification unit only when the object is detected,
- and wherein the detection apparatus is configured to detect the object when a detected volume exceeds a predefined first limit value and a detected pitch exceeds a predefined second limit value.
A detection apparatus, comprising an identification unit for identifying an object transported by a conveying device,
- wherein the detection apparatus has at least a first microphone and is configured to detect the object acoustically, in particular during transport, by means of at least the first microphone, and to initiate an identification process of the object by means of the identification unit only when the object is detected,
- wherein the detection apparatus is configured to record and evaluate a volume and a pitch of a sound influenced by the object by means of at least the first microphone in order to detect the object,
- and wherein limit values are predefined such that the limit values have a correlation to one another, which correlation takes into account a relationship based on the Doppler effect between the volume and the pitch of the sound influenced by the object when passing the detection apparatus.
A detection apparatus, comprising an identification unit for identifying an object transported by a conveying device,
- wherein the detection apparatus has at least a first microphone and is configured to detect the object acoustically, in particular during transport, by means of at least the first microphone, and to initiate an identification process of the object by means of the identification unit only when the object is detected,
- wherein the detection apparatus is configured to record and evaluate a volume and a pitch of a sound influenced by the object by means of at least the first microphone in order to detect the object,
- wherein the detection apparatus comprises a memory module on which memory module the volume and the pitch are recorded and/or limit values, a waiting time, a switch-off time, a distance value, and a second distance value, and/or a position value, and/or wherein the detection apparatus is configured so that the limit values, a waiting time, a switch-off time, a distance value, and/or a position value are defined during an installation process of the detection apparatus,
- and wherein the detection apparatus is configured, during the installation process in which the object passes the detection apparatus at least once, to store, for each passing of the object, the volume of the sound influenced by the object as a first reference pattern and the pitch of the sound influenced by the object as a second reference pattern in the memory module by means of at least the first microphone, and to determine the first limit value via the first reference pattern and to determine the second limit value via the second reference pattern.
