Abstract
A method and apparatus for monitoring a machine with at least one rotating component. In the method, accelerometer data collected for the machine is received by a data processing apparatus. An ellipse descriptive of movement of the machine in time domain and/or frequency domain is determined based on the accelerometer data. At least one ellipse parameter defining the ellipse is then used in monitoring the machine.
Claims16
A method for monitoring a machine with at least one rotating component by a data processing apparatus, the method comprising:
- receiving accelerometer data collected for the machine,
- determining an ellipse descriptive of movement of the machine in time domain and/or frequency domain based on the accelerometer data,
- determining at least one ellipse parameter defining the ellipse, and
- using the at least one ellipse parameter in monitoring the machine.
A monitoring apparatus comprising at least one processor and at least one memory including a computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus at least:
- receive accelerometer data collected for a machine with at least one rotating component,
- determine an ellipse descriptive of movement of the machine in time domain and/or frequency domain based on the accelerometer data,
- determine at least one ellipse parameter defining the ellipse, and use the at least one ellipse parameter in monitoring the machine.
