DEVICE AND METHOD FOR ONLINE-VISUALIZING NOISE USING UBIQUITOUS-CITY MIDDLEWARE

摘要

Disclosed is a device for online-visualizing noise in a three-tier u-city system based on a u-city middleware system. The present device comprises: a first tier portion, which can collect sensor values from various types of sensing devices, for receiving the sensor values and controlling connected sensors; a second tier portion for context-aware computing the sensor values received from the first class unit and converting same to context-aware values; and a third portion, which can reply to requests by applications having different characteristics, for generating online a noise map using the context-aware value of at least one region or the original noise information and space model information, and for visualizing the generated noise map on the U-city portal of a presentation tier, and the like. As a result, the noise map can be created immediately in response to an online request, and the online-visualized noise map can be provided to a user.
