Dynamic adaptation accessing method for heterogeneous sensing data

Sensor web enhancement( SWE) of open geospatial consortium defines heterogeneous sensor uniform description standard,but the process of underlying heterogeneous data access to SWE is not clearly defined,which will lead to manual operation for accessing to each type of heterogeneous data. To solve the problem,a sensor information model called HSIM is designed. HSIM not only describes sensor properties and observation ability,but also summarize sensor data structure and data transmission protocol; a method for adaptive accessing of heterogeneous sensor data is proposed,and the method achieves automatic parsing through dynamically generate adapter and access SWE automatically. Access meteorological heterogeneous data adapter access system proves that the proposed method can achieve automatic parsing and accessing of heterogeneous sensing data with less manual intervention,and the method provides an effective way for dynamic integration of heterogeneous data.
