Definitions
- the present invention relates to data communication through solid metal of apparatus used in harsh environmental conditions, such as in below ground surveying, exploration and testing in relation to the mining, oil and gas, and construction industries.
- a small mechanical compass on a gimbal is installed in a cylindrical probe which has a camera pointed at it. This probe may also have to be seated within a brass pressure barrel.
- a timer is set (before use) to initiate the mechanical camera to take a photograph of the compass after a certain time delay.
- the metallic cylindrical probe enclosure is re-sealed (within a pressure barrel) with waterproofing '0' rings and lubricant to prevent leakage and to guard against pressure build up in the harsh environment below the surface.
- the protective pressure casing is unscrewed and the camera with film is removed.
- An electronic probe may have an exposed plug or socket at one end or on the length of its body.
- a cable is connected between the probe and an external device to set up the probe before use.
- the probe After initiating set up, the probe is inserted into a pressure barrel which has '0' rings and is lubricant sealed to prevent leakage and pressure build up.
- the probe is then lowered into the drill hole for measurements.
- the probe is removed from the pressure barrel.
- Some probes have a number of switches and display mounted on the cylindrical probe casing itself.
- the probe is set up using the switches and display,
- the probe has an RF transmitter/receiver (transceiver) built into it which can be set up to start by a hand controller also fitted with an RF transceiver.
- transmitter/receiver transmitter/receiver
- a section of the probe body will need to be non-metallic to allow radio waves to be transmitted and received from the probe.
- the probe When ready for use, the probe is inserted into a water/pressure sealed brass barrel before inserting into the drill hole.
- the probe body has a section of see-through or infra-red material window which allows IR communication to take place.
- a hand held unit with similar IR interface circuitry is 'pointed' at the probe IR window where setup data instructions can be transmitted.
- the probe After retrieval, the probe is removed from the pressure barrel and data retrieved using an IR hand-held communicator. f) IR communication from a probe built into its own pressure barrel
- This unit has its IR communication window built into one end of its brass probe body.
- the exposed end will still have to have a pressure/water sealed screw-on cap with its own ⁇ ' rings and lubricant installed before inserting into the drill hole.
