APPARATUS AND METHODS FOR SELF-POWERED COMMUNICATION AND SENSOR NETWORK

摘要

A system for communicating between a first location and a second location comprises a jointed tubular string (4) having a first section (21) and a second section (22) connected at a connection joint (4), with the tubular string having a fluid (11) in an internal passage thereof. A first acoustic transducer (23) is mounted in the internal passage of the first section (21) proximate the connection joint (4), and a second acoustic transducer (25) is mounted in the internal passage of the second section (22) proximate the connection joint (4). A signal transmitted from the first location to the second location is transmitted across the connection joint as an acoustic signal in the fluid (11) from the first acoustic transducer (23) to the second acoustic transducer (25).
