Research on Engine Condition Detection Based on Telemetry Wavelet Reconstruction Technique

摘要

In this paper, telemetry technique and wavelet decomposition and reconstruction was employed, and experiment was performed at the test of F3L912 type four-stroke three-cylinder diesel engine. The engine condition detection method based on telemetry and wavelet reconstruction technique was proposed. This method can detect engine's condition during vehicle's traveling. The method also provides a feasible method to resolve the problem of no-outer load in stillness detection.
