摘要： A borehole sensor is presented including a three axis gimbal device for determining (1) a vertical plane, using the force of gravity as a reference, (2) a horizontal plane, using the force of gravity as a reference, and (3) the north direction, using the earth's magnetic field as a reference. A motor drive system drives parts of the mechanism to desired positions about the three axes, and error transducers determine the deviation from desired positions about the axes and provide feedback to the motor drive system to eliminate the error.

摘要： A control system is presented for controlling the operation of a borehole sensor. The borehole sensor includes a three axis gimbal device for determining (1) a vertical plane, (2) a horizontal plane, and (3) the north direction. Upon receipt of an initiation signal, the control causes a motor drive associated with each gimbal to drive error transducers on each gimbal to desired "home" positions about the three axes and error transducers determine the deviation from desired positions about the axes and provide feedback to the motor drive system to eliminate error. A home signal is generated when each error transducer reaches its home position. When home signals are received from all error transducers, the control system then senses the sign and magnitude of the error output from each error transducer and operates the motor drive system to drive the gimbals in directions to reduce the error. When each error transducer reaches its null position, the control terminates operation of its associated motor drive. The amount of movement of the motor drive required to drive the error transducer to its null position is measured to determine the deviation between the home position and the null position of the transducer. When all transducers have reached their null position the control operates to transmit the error measurements for recording or use.
