Tracking Smart Devices on Shop Floor
LOW-COST INDOOR LOCALIZATION SOLUTION FOR INDUSTRY 4.0 APPLICATIONS IN MANUFACTURING
At Fraunhofer IPT, we are realizing industry 4.0 through the adaptive digitalization and networking of machines, parts, personnel and other entities in the working environment, in order that information and instruction will be available everywhere and all the time in the production process. Thus, smart devices will play a very important role to help people being integrated into future manufacturing environment, as information need to be transferred faster and with the right level of detailing with respect to the individual need of the singular workers, factory managers etc. Currently, we are implementing an indoor localization system using Bluetooth beacons in the shop floor as part of an industry 4.0 demonstration environment. This sensor network is aimed to implement tracing and tracking of workers and working parts in future smart factories, as well as the to the networking of the smart wearables with existing manufacturing machines. In this paper, we firstly pre-sent the problem by such Bluetooth sensor networks, i.e. inaccuracy and instability of the sensor signals. To solve these problems, we are investigating various smoothing algorithms. With an industrial demonstrator, we present our low-cost solution for indoor localization in this paper.
