Research On The Method Of Multi-source Heterogeneous Data Collection And Fusion In Airport

The airport's current energy management is imperfect management situation, it can be found the relationship between energy consumption and airport operations through the data analysis, achieve the purpose of energy saving and emission reduction by improving related energy-saving measures. Because of many kinds, large scale, distributed storage of data collected, no correlation between various data, so the data integration is necessary.The main contents of this paper is to select the appropriate method to unify the various multi-source heterogeneous data collection, research airport multi-source heterogeneous data integration system, the composition and the specific fusion algorithm and validate fusion algorithm. First, according to the specific circumstances of the airport data, design data layer collection process, collection framework and realize the acquisition function finally. Then, based on the data collected to obtain improved integration level corresponding to the data layer, feature layer, decision layer based on multi-sensor data fusion, data fusion method batch estimation and confidence from the similarity-based heterogeneous data fusion,the fusion method of heterogeneous data integration based on knowledge element and multi source data fusion method and improved fuzzy set based on D-S evidence theory, also verify the effectiveness of the fusion algorithm. Finally, put the acquisition and integration of research findings into practice, designing airport running energy intelligent monitoring and analysis applications system to conduct a comprehensive data management of the airport operators. Besides, the results of data fusion process can be used to facilitate airport management.In this paper, multi-source heterogeneous data integration techniques are used to some of the operational data as a means to deal with the extensive management of the airport from the acquisition and integration. The feasibility of multi-source heterogeneous data fusion airport is verified based on the obtained results and data. It can be for further data mining to provide a reliable data base and can provide a reference for the practical application of the program.
