Abstract (en)
[origin: WO2011128068A2] The invention relates to a communication system for transmitting information relating to drilling rods of a drill string for earth boreholes. The system comprises a plurality of drilling rods (3, 4, 5, 6, 8, 9, 10, 80) which can be connected to one another, a drill drive (7) and a surface computer (100, 101), wherein at least a drilling rod (8, 80) has a receptacle for a drill head and sensors and/or actuators, to or from which data are to be transmitted to or from the surface computer (100, 101). In this case, each drilling rod is formed from a drill pipe (11) which is in the form of a hollow cylinder and has at least one line (21, 22) extending in the axial direction and has an upper end (13) and a lower end (14). Communication units, between which data is interchanged via the at least one electrical line (21, 22), are respectively arranged at the ends (13, 14), wherein the communication units (17, 19) transmit data to the respectively adjacent communication unit (17, 19) of the connected drilling rod by radio.
