Use of high speed radio frequency protocols for communication with pipeline pigs and inspection tools
A method and system of high speed radio frequency communication between an outside of a metallic pipeline or vessel and an interior volume contained by the metallic pipeline or vessel includes passing a high speed radio frequency signal through a communication portal having a high speed radio frequency permittive material exposed to the interior volume of the metallic pipeline and to the outside. The high speed radio frequency signal may be transmitted from the interior volume to the outside or from the outside to the interior volume. The communication portal may be a cylindrical- or planar-shaped body connected to the metallic pipeline. A tool located within the interior volume may transmit, receive, or transmit and receive the high speed radio frequency signal. The high speed radio frequency signal may be configured according to a 2.45 GHz standard protocol.
1. A method of high speed radio frequency communication between an outside of a metallic pipeline and an interior volume contained by the metallic pipeline, the method comprising:
passing a high speed radio frequency signal through one or more communication stents located along, and contained by, a wall of the metallic pipeline, said communication stents each being a cylindrical-shaped communication stent arranged perpendicular to a longitudinal axis of the metallic pipeline;
each said communication stent further comprising a high speed radio frequency permittive material and a wrapper located about the permittive material;
the permittive material and the wrapper differing from one another in compressive strength, the wrapper spanning at least an entire thickness of the wall, the permittive material having one end extending past an inner diameter of the wall into the interior volume of the metallic pipeline and another end extending past an outer diameter of the wall to the outside of the metallic pipeline.
2. The method of claim 1 , further comprising the high speed radio frequency signal being a signal transmitted from the interior volume to the outside.
3. The method of claim 1 , further comprising the high speed radio frequency signal being a signal transmitted from the outside to the interior volume.
4. The method of claim 1 , wherein the high speed radio frequency permittive material includes at least one material selected from the group consisting of polycarbonate, acrylic glass, polyvinylchloride, nylon, fiberglass, ceramic, mica, glass, and graphite.
5. The method of claim 1 , further comprising a tool configured to transmit, receive, or transmit and receive the high speed radio frequency signal.
6. The method of claim 5 , wherein the tool is selected from the group consisting of a tool configured to traverse at least a portion of the metallic pipeline, a tool configured to inspect at least a portion of the metallic pipeline, a tool configured to isolate at least a portion of the metallic pipeline, and a tool configured to tap into at least a portion of the metallic pipeline.
7. The method of claim 1 , wherein the high speed radio frequency signal falls within an industrial, scientific and medical (ISM) radio band selected from the group consisting of a 915 MHz band, a 2.45 GHz band, and a 5.8 GHz band.
8. A system of high speed radio frequency communication between an outside of a metallic pipeline and an interior volume contained by the metallic pipeline, the system comprising:
one or more communication stents located along, and contained by, a wall of the metallic pipeline, said communication stents each being cylindrical-shaped and arranged perpendicular to a longitudinal axis of the metallic pipeline;
each said communication stent further comprising a high speed radio frequency permittive material and a wrapper located about the permittive material;
the permittive material and the wrapper differing from one another in compressive strength, the wrapper spanning at least an entire thickness of the wall, the permittive material having one end extending past an inner diameter of the wall into the interior volume of the metallic pipeline and another end extending past an outer diameter of the wall to the outside of the metallic pipeline.
9. The system of claim 8 , further comprising one or more repeaters located along the metallic pipeline, each repeater being within a signal reception distance of a respective communication portal.
10. The system of claim 8 , wherein the high speed radio frequency permittive material includes at least one material selected from the group consisting of polycarbonate, acrylic glass, polyvinylchloride, nylon, fiberglass, ceramic, mica, glass, and graphite.
11. The system of claim 8 , further comprising a tool configured to transmit, receive, or transmit and receive the high speed radio frequency signal.
12. The system of claim 11 , wherein the tool is selected from the group consisting of a tool configured to traverse at least a portion of the metallic pipeline, a tool configured to inspect at least a portion of the metallic pipeline, a tool configured to isolate at least a portion of the metallic pipeline, and a tool configured to tap into at least a portion of the metallic pipeline.
13. The system of claim 8 , further comprising programmable control means located outside of the metallic pipe, the control means configured to transmit, receive, or transmit and receive the high speed radio frequency signal.
