System Designing and Plototyping on IoT for a Factory

In manufacturing fields, the deployment of IoT has been discussed for creating new functionalities of products and for enhancing the manufacturing efficiency. However, most machines in a factory do not support communication interfaces for IoT. This study proposes monitoring systems using sensors and wireless networks for machines used in manufacturing, which lack communication interfaces. In addition, this study proposes monitoring the power consumption of machines using clamping current sensors and the status of machines using color sensors. These monitoring schemes do not impact traditional machines that lack communication interfaces. Furthermore, the network performance of the proposed monitoring system and the implementation of prototyping systems are also discussed.
