SYSTEM FOR PROVIDING INFORMATION OF ATMOSPHERIC RISK USING USN VIRTUAL SENSOR

The present invention relates to a system for providing atmospheric risk information using a ubiquitous sensor network (USN) virtual sensor. The objective of the present invention is to provide atmospheric risk information in the form of consumer-oriented visualized information through a user terminal using USN-based measurement sensor information and virtual sensor values through air quality modeling. To achieve the objective of the present invention, the system comprises: a sensor unit which is a USN-based measurement sensor to measure air quality; an atmospheric environment management server which allocates virtual sensors to a specific space through measured information of the sensor unit and estimated values through air quality modeling, calculates and stores measured values, and transmits atmospheric risk information to a user terminal based on the position of the user terminal; and the user terminal which has a GPS mounted thereon, transmits input information to the atmospheric environment management server when the input information is input through a user′s touch or coordinate input, receives virtual sensor values from the atmospheric environment management server, and displays the virtual sensor values as visualized information.
