Abstract:
To improve the economic growth rate, all countries are committed to the concept of a smart factory. To upgrade the manufacturing equipment in a smart factory from automation to intellectualization, all the manufacturing information must be collected, analyzed, and used. To obtain the information, such as sensing, motion, actuation, etc., the concept of the Industrial Internet of Things (IIoT) must be imported into the factory. In a factory, the devices are made from different suppliers, so that information may not be easily exchanged between them. Hence a unified information format or communication protocol is very critical.
A bi-direction communication system for a smart factory is then designed and developed in this research. The communication protocol MQTT is installed in an embedded system, which is used as an intelligent IIoT gateway. The MQTT protocol is also installed into the controller of equipment, which will be used to collect sensing data, production information. The obtained data and information can be transmitted between different devices by using the MQTT protocol to achieve network communication between machines and IoT devices. By using the MQTT, a mobile application platform is also developed and implemented on the Android system, so that the required information can be obtained from heterogeneous communication interface easily.
