In-door location-based smart factory cloud platform supporting device-to-device self-collaboration

Recently, the rapid advancement of technology related to Internet of Things (IoT) has increased the development of smart factory that is intelligent manufacturing system based on IoT and cyber physical system. However, the general approach of smart factory does not present a realistic service model. In this paper, we present the indoor location-based smart factory (iLSF) platform, a service model for collaboration among factory workers, facilities, manufacturing materials, and factory control system. The iLSF collects the information from the factory through a protocol that supports self-collaboration among wearable devices, tags of machines, and anchor nodes. The proposed platform enables a worker to automatically configure a machine with their personally preferred value, and receives the working history from a machine. Finally, we suggest various specific service scenarios such as a safety notification to workers in a dangerous environment and a guide to workers informing them of the proper manufacturing process.
