schaltungsanordnung to transfer information between erfassungseinrichtungen for seismic data and a central registriereinrichtung and method for testing such a schaltungsanordnung

摘要

A device for transmitting seismic data informations from acquisition devices of a seismic streamer to a central recorder an a ship, comprises at least two outward, and at least tow inward transmission lines made up of line sections interconnected by interconnection systems including means for the reconfiguration of signals, means for detecting order signals receives at said interconnection systems and switching means, and controlled by the detection means to connect different line sections, previously tested, and to by-pass faulty sections so as to form one outward and one inward continuous transmission line in good operating condition.
