These tools can measure and remotely monitor power-use and process status parameters to enable analysis and improvements of energy usage. Our approach exploits the ability to use a wide-range of sensor devices combined with data analysis based on context knowledge of the measurands to facilitate the identification of significant energy-savings opportunities. Using these tools, the authors have identified energy savings opportunities for several manufacturing processes by monitoring and analyzing real-time, process-related information in conjunction with electric power consumption data. Specifically, it has been found that some energy savings opportunities are only apparent after combining synchronously-collected, machine and process information with power-use profiles. In this paper, examples of applying this approach to various manufacturing processes from different product sectors are discussed. 收起
