Abstract

The present invention relates to a vibration monitoring device and methods for using the same. Specifically, the invention relates to a vibration monitoring device which may be utilized throughout a delayed coker unit operation to ascertain whether the cutting tool is boring, cutting or ramping mode.

Claims

1. A device for monitoring the cutting tool in a delayed coker unit operation, comprising:

a vibration sensor; and

a computer system.

2. The device of claim 1, further comprising an operator who utilizes the computer system to remotely detect the status of the cutting tool while operating a de-coking apparatus.

3. The device of claim 1, wherein said vibration sensor is utilized to remotely determine when a cutting tool is switched between boring and cutting modes.

4. The device of claim 3, wherein said detection is accomplished without raising the drill tool out of the coke drum for mechanical alteration for inspection.

5. The device of claim 1, further comprising a visual display which allows an operator to determine what mode a cutting tool is present in.

6. The device of claim 1, further comprising vibrational data, which is utilized to provide information regarding the mechanical status of the cutting tool of a blade de-coker unit.

7. The device of claim 1, wherein said vibration sensor is an accelerometer.

8. The device of claim 1, wherein said vibration sensor is attached to more than one location in a delayed de-coker operation.

9. The device of claim 1, further comprising a wireless relay device which communicates data between said vibration sensor in said communicator system.

10. The device of claim 1, wherein said vibration sensor is hardwired to said computer system.

11. The device of claim 1, further comprising output signal from said vibration sensor, and software resident on said computer which receives said output signal and coverts the same into a usable wave form.

12. The device of claim 11, wherein said data is routed to a fast fourier transform.

13. The device of claim 12, wherein said signal is converted into a fast fourier transform fingerprint which may be utilized as a signature associated with any particular cutting mode.

14. The device of claim 13, wherein said cutting mode is said boring mode.

15. The device of claim 1, wherein said mode is in cutting mode.

16. The device of claim 1, further comprising:

an accelerometer wherein the accelerometer provides an output signal;

at least one network access point which receives the output from the accelerometer;

software resident on said computer system for converting the raw output signal into a useful wave form; and

a display apparatus which informs an operator about the status of a cutting tool in a coke drum.

17. A vibration monitoring device, comprising:

a housing;

a transducer coupled at a position in a delayed coker unit operation, the transducer providing an output signal representative of the movement of a cutting tool;

a Fast Fourier Transform which modifies, the output signal; and

a display which indicates the operational status of the cutting tool.

18. A system for determining the Fast Fourier Transform wave pattern associated with the cutting, boring and ramping modes of a cutting tool inside a coke drum comprising:

a vibration sensor generates data;

a central processing unit which converts the data to a useable waveform; and

a central processing unit which identifies whether a cutting tool is boring or cutting; and

a display operatively connected to said central processing unit.

19. A method of determining status of a cutting tool in a delayed coker operation, comprising:

mounting a transducer a position in a delayed coker unit operation to provide an output signal related to movement of the drill stem;

processing the output signal; and

determining whether the cutting tool is cutting or boring.

20. The method of claim 19, wherein said determining is accomplished without raising the drill tool out of the coke drum for mechanical alteration for inspection.

21. The method of claim 19, further comprising transmitting the output signal from said transducer to a wireless relay device;

and communicating data between said wireless relay device to said computer system.

22. The method of claim 19, wherein said determining further comprises the steps of receiving data from said vibration monitor;

and coverting the same into a usable wave form.

23. The method of claim 22, wherein said converting comprises transforming said signal into a fast fourier transform fingerprint which may be utilized as a signature associated with any particular cutting mode.

24. The method of claim 19, further comprising:

routing said output signal to at least one network access point;

transmitting said signal from said access point to said computer system, wherein software resident on said computer system converts the raw data into a useful wave form; and

displaying the status of a cutting tool in a coke drum.
