【Abstract】 Aiming at the management difficulties and potential safety hazards caused by the large number and types of equipment in the electronic process laboratory, a non-intrusive load state monitoring system was developed by using the Internet of Things technology. The system includes monitoring nodes and servers. The former is used for load status identification, and the latter is responsible for statistics and control. At the same time, in order to accurately identify the equipment state on the node, a non-intrusive load state monitoring algorithm is designed at the monitoring node end, including multi-state load separation, state feature extraction and load identification processes. Experimental results in real-world scenarios show that the developed system can accurately monitor the equipment in the electronic process laboratory.更多还原
