Abstract:
1. A system for collecting and storing performance data for an engine, the system comprising: at least one sensor configured to generate one or more sensor data signals representative of one or more engine data performance parameters; a data sampling component configured to sample the sensor data signals at a data sampling rate; a data quantizing component configured to generate a plurality of quantized data samples corresponding to the sampled sensor data signals; a data storage sampling rate component configured to determine a data storage sampling rate for the quantized data samples, based on an analysis of at least a subset of the quantized data samples; a data encoding component configured to encode the quantized data samples according to the data storage sampling rate; a data storage component configured to store the encoded data samples from the data encoding component; and a data buffer component configured to store the quantized data samples at the data sampling rate and to capture and store one or more transient data segments comprising the quantized data samples, wherein the transient data segments are indicative of an operational condition in the engine, wherein the data storage sampling rate component is configured to detect an anomalous event based on the one or more transient data segments and to modify the data storage sampling rate in response to the detection of the anomalous event.
