Definitions

  • This invention relates to a data transmission system.
  • the invention relates to magnetic induction transmission, over a distance, of data such as voice, measurements ⁇ computer bytes, video, etc, that is any analogue or digital signals that can be processed onto a modulated carrier or; in such configuration that it can be Q transmitted and recognised by the systems using this invention.
  • a data transmission system comprising means for generating a S magnetic field means -for effecting variations to said magnetic field in correspondence with data to be transmitted, means for transmitting said varied magnetic field, and means for receiving and decoding said transmitted magnetic field in order to retrieve the transmitted data.
  • a method of transmitting data comprising the steps of generating a magnetic field; varying said magnetic field in correspondence with data to be transmitted, transmitting 5 said varied magnetic field and receiving and decoding said transmitted magnetic field in order to retrieve the carried data.
  • the invention involves the transmission of signals by generation of a recognisable magnetic field (preferably by modulation) and reception of the signal by measurements of the transmitted magnetic field as a vehicle for transfer of information.
  • a data transmission system comprises a magnetic field transmitter 1 which receives data from a number of data collection devices 2 which in the particular application illustrated could be temperature, pressure, flow rate; etc.
  • the transmitter 1 is located in a bore hole 20 and encodes the data transmitting it through the creation of a modulated magnetic field, which is received by a receiver 10 located, for example, on the sea ⁇ bed.
  • the receiver may be a receiver 11 located on a drilling platform, a receiver 12 located on a floating vessel or a receiver 13 located on-shore.
  • the generation of the transmitted magnetic field may be provided, for example; by electrical coil induction within a body of matter; the reception being made by measurements with sensors responding to magnetic field variations such as magnetometers, Hall effect generators, fluxgates, induction coils, etc.
  • this invention has a large variety of applications making use of signal differentiation by frequency or amplitude modulation; phase shift or rotation, time delay, etc.
  • the invention finds applications in the transmission of signals in environments not easily permeable to, or saturated by, electro-magnetic waves; such as environments buried within or shadowed by a large land mass, concrete shelters or other constructions; under water, etc.
  • the invention is particularly useful for the transmission of data and information collected deep inside hydrocarbon or geothermic wells, where pressures, temperatures and flows are recorded for good management of the reservoirs; inside mines and natural caves for communication and safety; underwater for communication, navigation and data gathering between surface and submerged boats, beacons, automatic recording stations, remotely operated wellheads, etc. all without the use of hard wired links between the transmitter and receivers.
  • the described mode of transmission is not limited to earth bound applicatons, and the invention has application in space or within or outside of anybody of matter, provided that this body of matter does not, by the physics of its properties, attenuate too quickly the magnetic field (principal mode of transfer of information) generated for the signal transmission.
