Application of Bluetooth low energy indoor positioning to optical lenses manufacturing factory

Abstract

Indoor positioning systems (IPSs) provide physical location information of indoor targets (i.e., people or devices). Traditional optical lens manufacturing companies must enable the operator and customers to grasp the progress of optical lens production, a goal that the global manufacturing industry has been now pursuing. This study incorporates an IPS design into the manufacturing and processing procedures of optical lenses and uses an indoor positioning algorithm to calculate location-based information to achieve effective indoor positioning. Therefore, in this paper, this study proposes that using Bluetooth low energy sensors to perform signal strength fingerprinting identification can increase the accuracy of positioning. The results reveal that the proposed method can attain a certain level of accuracy in indoor positioning, and integrated into the optical lens production management systems, to achieve optical lens smart manufacturing.
