Abstract

Methods and systems to achieve highly efficient rotational machine integrity determinations in which at least one sensor (106) senses indicia (105) such as time-varying rotational indicia from a rotational motive apparatus (103) and a processor (108) may provide many different functions including but not limited to operational function energy apportioning decisional processing, data compression, intelligent hierarchical data ranking, differential data processing, or the like perhaps to generate information (109) such as a rotational integrity abridgment transmissor to which an abridgment transmissor electromagnetic signal (112) may be created and perhaps even transmitted from a rotational motive apparatus to facilitate a machine integrity determination.

Claims

1. A high efficiency rotational machine integrity determination system comprising:

a time-varying rotational indicia sensor being an on-machine sensor configured to generate rotational waveform data from sensed time-varying rotational indicia responsive to a rotational motive apparatus rotational waveform data;

a programmed data transformation processor generating differential data by transforming the rotational waveform data, the programmed data transformation processor including an intelligent hierarchical data ranking decisional element that sets dynamic priorities for ranking of said differential data, said differential data comprising rotational motive apparatus operational information to establish a machine integrity determination and ranked data utilized to provide compressed differential data,

wherein said differential data comprises subtracted data; and

an abridgment transmissor electromagnetic signal transmitter comprising a reduced power requirement to achieve a transmission of an abridgment transmissor electromagnetic signal from said rotational motive apparatus to facilitate the machine integrity determination based on said differential data, the abridgment transmissor electromagnetic signal transmitter further comprising a differential data transmissor, the abridgment transmissor electromagnetic signal comprising the compressed differential data, the reduced power requirement being less than power requirement for a hand-held unit or other wireless vibration sensor utilizing battery power.

2. A high efficiency rotational machine integrity determination system according to claim 1 wherein said subtracted data comprises a difference between data based on said rotational waveform data and an element selected from a group consisting of historical data, standard data, curve fit data, reference data, and any combination thereof.

3. A high efficiency rotational machine integrity determination system according to claim 1 and further comprising a differential data compression system.

4. A high efficiency rotational machine integrity determination system according to claim 3, wherein the ranked data comprises high ranked data and low ranked data.

5. A high efficiency rotational machine integrity determination system according to claim 4, wherein the differential data compression system compresses at least part of the differential data in accordance with the ranked data.

6. A high efficiency rotational machine integrity determination system according to claim 5, wherein the at least part of the differential data comprises the high ranked data in which a power requirement threshold is not yet reached.
