Method and device for mounting and detecting a marker in a sewer or pipe system

A method for detecting a marker in a pipeline and/or sewer system, wherein the marker is mounted at a specific area in the pipeline and/or sewer system, wherein the marker comprises an RFID transponder, wherein

• an inspection and/or maintenance system, which has an RFID reader, is moved or advanced in the pipeline and/or sewer system until the RFID reader detects the RFID transponder,
• the RFID reader or a data processing device coupled to the RFID reader ascertains the position of the RFID transponder relative to the RFID reader, and
• the ascertained position of the RFID transponder relative to the RFID reader is used to ascertain the specific area at which the marker is mounted.

A device comprising a carriage of a sewer inspection and/or maintenance system, on which an arm is arranged, which is movable with a plurality of degrees of freedom relative to the carriage, wherein

• at a free end of the arm, receiving means is provided for receiving a marker, in particular an RFID transponder,
• the arm is configured to move the receiving means with the marker received thereby to a predetermined area in a pipeline and/or sewer system, and
• the receiving means is configured to mount the marker at the predetermined area.
