A method of data acquisition for health management of systems is provided. The method includes receiving, at a remote node, analog data from one or more sensors configured to monitor a health characteristic of a system, converting, at the remote node, the analog data into digital data, time stamping the digital data with the remote node, recording the digital data in a memory of the remote node, wherein the memory is a ring buffer, transmitting, from the remote node to a central device, requested digital data upon receiving a request related to a triggering event, and synchronizing the transmitted data at the central device based on the time stamp of the requested digital data to generate synchronized data.

Systems and methods for remotely triggered data acquisition

A method of health management of a monitored system includes collecting component condition indicator data used to calculate a plurality of component health indicators. Component fault severity and potential failure modes are determined utilizing the component condition indicator data. The potential failure modes are ranked in order of likelihood to isolate the failure mode. A system of health management for monitored apparatus includes a fault severity module to derive a plurality of component health indicators from collected component condition indicator data, the plurality of component health indicators indicative of fault severity of a plurality of components. A fault isolation module separately derives a ranked listing of potential fault/failure modes utilizing the component condition indicator data. The system further includes a communication portion to which the plurality of component health indicators and the ranked listing of fault/failure modes are transmitted for review and/or action by cognizant personnel.
