Abstract :
An environmental electromagnetic field measurement system that is characterized by a mobile distributed architecture is proposed. The system allows to monitor a wide area in an urban environment, and to analyze measurements so that potential ´critical´ locations can be singles out like those where the measured data overcome fixed warning levels, so that suitable corrective actions can be taken. The main advantage of the proposed system is the capability to monitor the spatial and temporal evolution of electromagnetic field over a larger area than using fixed probes. Moreover the architecture allows to collect data from different clients and to send them to a remote server for analysis purposes, which in turn leads to the evaluation of possible correlations that are useful to the process study. The measurement system also provides the integration of data with information like population density: the aggregated information qualifies the results, when areas with different population densities are put in comparison. Eventually, interpretation of acquired data is performed by an innovative fuzzy decision-making procedure, using suitable decision rules in order to minimize risks and costs according to metrological and statistical features of measurement system.
