Abstract

A system for inserting and orienting a probe into a machine includes a probe, a cable insertion unit, and a computer communicatively coupled to both the probe and cable insertion unit. The probe includes at least one sensor and a cable. Further, the at least one sensor produces at least one signal. The cable insertion unit is configured to orient and feed the probe. The computer includes an installed digital model of the machine. Further, the computer is configured to receive the at least one signal from the probe and produce a location model. The location model includes at least one of a two dimensional or three dimensional model representing the probe'"'"'s real-time location relative to the machine. As such, the cable insertion unit orients and feeds the probe into the machine under the guidance of the computer.

Claims

1. A system for inserting and orienting a probe into a machine, the system comprising:

a probe, comprising at least one sensor and a cable, the at least one sensor producing at least one signal;

a cable insertion unit configured to orient and feed the probe; and

a computer communicatively coupled to both the probe and the cable insertion unit, the computer comprising an installed digital model of the machine, the computer configured to receive the at least one signal from the probe and produce a location model, the location model comprising at least one of a two dimensional or three dimensional model representing the probe'"'"'s real-time location relative to the machine,

wherein the cable insertion unit, under the guidance of the computer, orients and feeds the probe into the machine.

2. The system of claim 1, wherein at least one sensor comprises an optical sensor.

3. The system of claim 2, further comprising a first display configured to show the video signal from the optical sensor.

4. The system of claim 1, wherein at least one sensor comprises a proximity sensor.

5. The system of claim 1, wherein the computer further comprises a probe computing unit and a processor with memory, the probe computing unit configured to receive the signal from the probe and create a modified signal, the processor with memory configured to store the digital model of the machine and receive the modified signal from the probe computing unit, the processor further communicatively coupled to and in control of the cable insertion unit.

6. The system of claim 1, wherein the cable insertion unit comprises a 3D gimbal with servo motor control on each of three axes.

7. The system of claim 3, further comprising a second display configured to show the location model representing the probe'"'"'s real-time location relative to the machine.

8. The system of claim 1, wherein the probe further comprises at least one other sensor, the signal from the sensor(s) transmitted to the computer and used by the computer to determine the real-time location of the probe.

9. The system of claim 1, wherein the computer is communicatively coupled to at least one control system of the machine, the control system used to manipulate the machine before, after, or while orienting and feeding the probe into the machine.

10. A method of automated probe insertion into a machine, the method comprising:

attaching a cable insertion unit to the machine at an access port;

feeding a probe into the cable insertion unit, the probe comprising at least one sensor and a cable;

transferring a signal from the probe to a computer installed with a digital model of the machine, the computer configured to produce a location model representing the probe'"'"'s real-time location relative to the machine, the computer further communicatively coupled to and in control of the cable insertion unit; and

inserting the probe into the machine using the cable insertion unit under the guidance of the computer, the computer automatically sending signals to the cable insertion unit to feed and orient the probe.

11. The method of claim 10, further comprising receiving a new signal at the computer from changing data at the probe.

12. The method of claim 11, further comprising changing the real-time location of the probe in the location model based on the new signal.

13. The method of claim 12, wherein changing the real-time location of the probe comprises recognizing a known location in the signal and altering the real-time location of the probe to that location in the location model.

14. The method of claim 11, further comprising altering the insertion speed and orientation automatically via the computer to lead the probe to a desired target location.

15. The method of claim 10, further comprising setting an initial location of the probe in the location model to the access port of the machine.

16. The method of claim 10, further comprising sending a signal from the computer to the probe to generally adjust an orientation of a probe tip.

17. The method of claim 10, wherein the guidance of the computer comprises an algorithm that learns the most efficient method of moving the probe to a target location, by storing and processing data from multiple insertions to the same or similar target locations.

18. A method for determining the real-time location of a probe in a machine, the method comprising:

placing the probe near an internal object that has a known location, the probe comprising a sensor and cable;

transferring a signal from the probe to a computer installed with a digital model of the machine; and

producing a location model of the real-time location of the probe in relation to the machine.

19. The method of claim 18, wherein the probe further comprises at least one other sensor, a signal from the other sensor transferred to the computer to determine the real-time location of the probe in the location model.

20. The method of claim 19, further comprising displaying the location model on a display.
