Abstract
In one embodiment, the disclosed method includes controlling operation of a machine system via actuators and a first set of signals received from sensors, receiving a second signal from a vibration sensor, calculating vibration parameters based on the second signal. The method further includes the steps of normalizing each of the vibration parameters and presenting the normalized vibration parameters in an operator interface. In another embodiment, the system includes a controller configured to receive sensor signals from a machine system and to control operation of the machine system via actuators. The system also includes a condition monitoring user interface configured to display normalized vibration parameters for the machine system.
Claims21
A method for vibration condition monitoring and controlling a machine system, comprising:
- controlling operation of a machine system via sending control commands to actuators and receiving a first signal from at least one sensor, the controlled machine system producing vibration during operation;
- receiving a second signal from a vibration sensor coupled to the machine system and detecting the vibration produced;
- calculating vibration parameters based on the second signal;
- normalizing each of the vibration parameters, wherein normalizing each of the vibration parameters comprises scaling each of the vibration parameters;
- and
- presenting the normalized vibration parameters in an operator interface during controlled operation of the machine system.
A machine control and condition monitoring system, comprising:
- a controller configured to receive sensor signals from a machine system and to control operation of the machine system via actuators;
- wherein the controller processes vibration measurement data and calculates the normalized vibration parameters;
- and
- wherein normalizing each of the vibration parameters comprises scaling each of the vibration parameters;
- and
- a condition monitoring user interface configured to display normalized vibration parameters for the machine system during controlled operation of the machine system.
A machine system controller, comprising:
- computer code to control operation of a machine system via actuators;
