Integrated Platform for Building Diagnostics Assessment
The proposed platform is the communication node among several facilities in the Smart City. The platform must be independent from infrastructures present as the lower level, but on the other hand, should allow centralized data acquisition. Each facility can be seen as a vertical structure, while the platform is a horizontal structure providing communication among vertical systems. The main goal of the platform is to improve efficiency of the systems under energetic, monetary and citizens welfare point of view. Platform is able to redistribute to researchers and operators data collected, aggregated, diagnostics indexes and Key Performance Indicators (KPI).
Currently, platform has been designed for three main facilities: public lighting, buildings network and mobility infrastructures. It is inspired by the structure of existing SCADA systems. A SCADA (Supervisor Control and Data Acquisition) is mainly composed of a Database o and several modules, which perform functions as data acquisition, actuation, alarms management. The added value of the platform is the capability to perform advanced diagnostics through data fusion of heterogeneous data collected: high-level assessment on the system state is achieved through aggregation of low-level data.
The platform is divided into five layers: presentation, business intelligence, datawarehouse, sensor interfacing and field bus layer.
