Data communication system

摘要

A system for communicating between a first unit and a second unit without a physical connection, the system including a magnetic element for creating a magnetic field, a sensor operatively arranged to detect changes in the magnetic field, and a driver operatively arranged to alter the magnetic field detected by the sensor in accordance with a first signal, the first signal operatively arranged to transmit data independent of an amplitude of the first signal, the sensor generating a second signal in response to changes in the magnetic field, the second signal representative of the first signal.

1. A system for communicating between a first downhole unit and a second downhole unit without a physical connection, the system comprising:
a magnetic element for creating a magnetic field, the magnetic element disposed at the first downhole unit; a sensor operatively arranged to detect changes in the magnetic field, the sensor disposed at the second downhole unit, the sensor configured to be positioned within the magnetic field when the first downhole unit is physically coupled to the second downhole unit; and, a driver operatively arranged to alter the magnetic field by changing a position of the magnetic element relative to the sensor in accordance with a first signal, the first signal operatively arranged to transmit data, the sensor configured to be positioned within the magnetic field and generate a second signal in response to changes in the magnetic field, the second signal representative of the first signal.
