Proposal of Smart Tags for Production System

Abstract

This study was conducted to facilitate implementation of the Internet of Moving things (IoMT), which refers to sensing locations and conditions of moving things during manufacturing. For manufacturing, machinery and robots with installed IoT devices are useful for anomaly detection and facility maintenance. The Radio-frequency identification device (RFIDs), bar codes and QR codes are also used to control products, parts, and work-in-process because they can be introduced easily and at low cost. Nevertheless, these technologies are unsuitable for construction of sensor networks sensing locations and conditions of moving things during manu-facturing. Therefore, this study presents a proposal of a smart tag that enable to construct the sensor network for moving things. First, requirement for smart tags and sensor networks is defined. Then developed prototype of smart tags are evaluated the positioning accuracy and sensing condition through experiments. These results pro-vide guidelines for the introduction of the IoMT.
