Smart manufacturing demands industrial Internet of Things (loT) that encompasses components such as sensors, industrial control systems, programmable logic controllers, gateways, wireless devices, machine series connection modules, and edge computing hosts. However, these components often use different communication protocols, and collecting, transmitting, and integrating device source data. In this study, data regarding a coating process were collected and transmitted to a data server in real-time over Bluetooth for presentation and storage. The data were then processed and analyzed to optimize production. Specifically, a supervisory control and data acquisition (SCADA) system based on Bluetooth low energy (BLE) modules was developed. The system comprised a self-developed BLE gateway that interfaced wirelessly with multiple self-developed Bluetooth devices for collecting equipment and sensor data. These devices used the Modbus TCP or RTU protocols to collect sensor data, and converted and transmitted the data to the data server. Subsequently, the data were displayed, stored, and analyzed by the graphical control system, improving manufacturing efficiency.
