Extracted Abstract:
.In the paper we propose ontology based scientific visual- ization tools to calibrate and monitor various IoT devices in a uni- form way. We suggest using ontologies to describe associated controllers, chips, sensors and related data filters, visual objects and graphical scenes to provide self-service solutions for IoT developers and device makers. High-level interface of these solutions enables composing data flow dia- grams defining both the behavior of the IoT devices and rendering fea- tures. According to the data flow diagrams and the set of ontologies the firmware for IoT devices is automatically generated incorporating both the data visualization and device behavior code. After the firmware load- ing, it’s possible to connect to these devices using desktop computer or smartphone/tablet, get the visualization client code over HTTP, mon- itor the data and calibrate the devices taking into account monitoring results. To monitor the distributed IoT networks a new visualization model based on circle graph is presented. We demonstrate the imple- mentation of suggested approach within ontology based scientific visual- ization system SciVi. It was tested in a real world project of an interactive Permian Antiquities Museum exhibition creating.
