Internet of Things for Coil-Winding CNC Machines

The internet of things (IoT) plays an important role in monitoring machines, productions and inventory management in smart factories. It helps to improve labor productivity, automatic system management, and devices maintenance. This paper presents the IoT framework and the results of research, design, and fabrication of the Wi-Fi wireless communication and control IoT system for coil winding CNC machines. A coil winding CNC machine includes three motors: one for releasing winding, one for winding coil and the other for spreading wiring. Each wound- or releasing-winding motor is controlled by an individual inverter, while the spreading winding motor is controlled by a servo drive. The whole electrical drive is monitored and controlled by its Supervisory Control and Data Acquisition (SCADA) including electronic hardware and software. This paper focuses on the design of electronic hardware, communication firmware, and computer and smart phone software for monitoring parameters of a coil winding CNC machine.
