摘要： A method of monitoring a condition of a system is provided. The method includes receiving a first sampled signal having first sampled points sampled at a first sampling rate, and receiving a second sampled signal having second sampled points sampled at a second sampling rate. Both the first and second sampled signals originate from sensing over a dimension in the same sensing process. The method further includes determining a first shift over the dimension between the first sampled signal and the second sampled signal at a first sampled point of the first sampled signal, determining a second shift over the dimension between the first sampled signal and the second sampled signal at a second sampled point of the first sampled signal, the second sampled point being different than the first sampled point, determining a calculated shift that is a function of the first shift and the second shift, generating a merged signal that includes each of the first sampled points and each of the second sampled points shifted based on the calculated shift, determining whether there is at least a threshold indication of failure based on analysis of the merged signal, and disabling or recommending for removal the component in response to determining that there is at least a threshold indication of failure.

摘要： Rotational speed of a rotating component is determined using frequency domain vibrational data. A time sequence of vibrational data of the rotating component is sensed and converted to the frequency domain vibrational data. A portion of the frequency domain vibrational data corresponding to an expected rotational speed of the rotating component is identified. A frequency bin index of the frequency domain vibrational data corresponding to a maximum vibration within the portion of the frequency domain vibrational data is identified. The maximum vibration at the identified frequency bin index and vibrations associated with adjacent frequency bin indices are fitted to a model curve. A floating point frequency bin index corresponding to a maximum of the model curve is identified, and the rotational speed of the rotating component is determined based on the frequency bin index corresponding to the maximum of the model curve.

摘要： A health monitoring system includes at least one sensor. A health monitoring unit (HMU) is operatively connected to the at least one sensor to receive data therefrom and to generate at least one status indicator (SI) based on the data from the at least one sensor. A computing device is operatively connected to the HMU to receive data therefrom and is configured to generate a health notification when a quantity of the SI that are greater than or equal to a pre-determined SI threshold exceed a pre-determined peak count threshold. A method for monitoring and determining the health of a component includes collecting data during a sample cycle from at least one sensor to generate a numerical SI for a given component with a computing device. The method includes identifying if the numerical SI qualifies as a peak SI, which is greater or equal to a pre-determined SI threshold.
