Real-time abnormality detection and classification in diesel engine operations with convolutional neural network
作者:
Highlights:
• Fluctuations in the rotational speed of prime mover are translated in to a CAD signal to observe the behavior of the engine IC process.
• Combined detection of cylinder misfires and engine load conditions is an important tool in advanced engine control systems.
• A CNN-based classifier extracted the feature from CAD signals and detected multiple irregularities in each IC cycle of the engine operation in real-time.
• Low computation complexity and a lower prediction time by proposed shallow CNNbased classifier.
