A One-Stage Ensemble Framework Based on Convolutional Autoencoder for Remaining Useful Life Estimation.As the legislative pressure to reduce energy consumption is increasing, data analysis of power consumption is critical in the production planning of manufacturing facilities.  In legacy studies, a machine conducting a single continuous operation has been mainly observed for power estimation.  However, the production machine of a modularized line, which conducts complex discrete operations, is more like the actual factory system than an identical simple machine.  During the information collection of this kind of production line, it is important to interpret mixed signals from multiple machines to ensure that there is no reduction in the information quality due to noise and signal fusion and discrete events.  A data pipeline-from data collection (from different sources) to preprocessing, data conversion, synchronization, and deep learning classification-to estimate the total power use of the future process plan, is proposed herein.  The pipeline also establishes an auto-labeled data set of individual operations that contributes to building an power estimation model without manual data preprocessing.  The proposed system is applied to a modular factory, connected with machine controllers, using standardized protocols individually and linked to a centralized power monitoring system.  Specifically, a robot arm cell was investigated to evaluate the pipeline, with the result of the power profile being synchronized with the robot program.
