BrickIoT: Plataforma interactiva para monitoreo y visualización de sensores IoT en edificios inteligentes con ontología brick

Abstract

CONDITION FOR PUBLICATION OF PROJECT. research proposes a schema based on the Brick ontology with the aim of establishing a standardized and unified representation of the infrastructure at the Escuela Superior Politécnica del Litoral (ESPOL) campus. The main objective is to enhance the semantic description of the campus architecture by establishing precise relationships between the data generated by sensors and their corresponding physical locations. In this study, the proposed schema was limited to Building 11C of the Faculty of Electrical and Computer Engineering, incorporating laboratories, outdoor areas, zones, equipment, and sensors, and evaluating its expressiveness in comparison with an equivalent model based on Haystack, currently implemented, in order to optimize interoperability and information organization. Additionally, using Brick’s standardized dictionary, IoT devices and sensors were integrated into the schema to develop an automated system capable of semantically mapping data points to their respective physical locations within the building. For the development of the schema, technologies such as Python with the RDFLib library were used to model the infrastructure in RDF and Brick, while Django, React, and ReactFlow were used for data integration, management, monitoring, and interactive visualization. The resulting system enabled a semantic representation of the relationship between sensors and locations, improving interoperability and reducing semantic variability.
