Abstract

Systems, methods and devices are provided that allow more efficient transfer and processing of sensor information in a hierarchical data system. The system provides for a plurality of component area managers (CAM), each of the CAMS being in operable communication with at least one of a plurality of transducers that monitors a phenomena of a component and in operable communication with a data bus. A CAM comprises a processor in operable communication with the at least one transducer of the plurality of transducers, wherein the first processor is configured to record data generated by the at least one transducer of the plurality of transducers, to reduce the recorded data, to place the reduced data on the data bus. The system also includes a transducer selection module controlled by the first processor by which the first processor selects one of the plurality of transducers to record and a rolling buffer in operable communication with the first processor and in operable communication with the at least one transducer by which to record the data generated by the at least one transducer of the plurality in a first-in-first-out manner.
