Abstract
A method and apparatus for assisting an operator in a coke cutting operation wherein both a graphic and audio display of the operation are provided. The vibration of the coke drum is measured and after filtering, is recorded on a chart recorder and its amplitude converted to a related audio signal.
Claims3
A method for assisting an operator in cutting coke in a coke drum comprising:
- measuring the vibrations produced in the coke drum during a coke cutting operation;
- filtering the measured vibrations to obtain the frequencies between 1000 and 2000 hertz;
- displaying graphically said frequencies of interest;
- and
- forming an audio display of the amplitude of said frequencies whereby said operator can observe the graphic display and listen to the audio display during the coke cutting operation.

An apparatus for assisting an operator in cutting coke in a coke drum comprising:
- vibration measuring means disposed to measure the vibration of the coke drum;
- amplifier and filter means coupled to said vibration measuring means, said filter means being adapted to remove all frequencies outside the range of 1000 to 2000 hertz;
- graphic display means coupled to the amplifier and filter means for displaying the amplitude of the amplified and filtered signal;
- and
- an audio display coupled to the amplifier for producing an audible signal.
