The present invention relates to a technology for measuring noise and vibration, and in particular, management of noise and vibration using a USN suitable for monitoring and managing noise and vibration in urban areas using a ubiquitous sensor network (USN). It relates to a method and a system.

At present, it is compulsory to understand the noise and vibration status in all administrative jurisdictions under the Noise and Vibration Control Act. For this purpose, a noise measuring network is installed and measured, and the measured data are provided to the Minister of Environment on a quarterly basis. Measurement and reporting are mandatory (Noise Vibration Control Act). However, in the remaining regions except 17 cities in five cities (targeted for automatic measuring network operation), a limited number of public officials measure each quarter with a measuring instrument at the measuring point, and process the measured data separately. In case of automatic measuring network, wired network is used, so the instrument is installed in the area where power line is supplied and the collected data is transmitted to the central server through the Internet.

As such, the noise and vibration measurement method using a conventional automatic measuring network is connected to a wired network or transmitted to a nearby access point (AP) through a wireless Internet for analysis by a central server and a geographic information system (Geographic Information System). , Which will be referred to as GIS).

However, the wireless LAN interface using 2.4GHz frequency between the instrument and the access point is suitable for indoor use because of its narrow coverage and difficulty of guaranteeing the quality of service (QoS) due to the characteristics of the Industrial, Scientific, and Medical (ISM) band. However, most of the noise emissions are caused by traffic (cars, trains, aircraft), construction plant noise, and facilities requiring a calm environment. In this case, noise measurement data is collected by wireless LAN. Sending to a central processing server is less effective.

As a result, in the conventional noise measuring method, the measuring instrument was connected to a wired network or a wireless LAN interface to measure the noise. When a reference value or more occurred, the measurement data was stored and managed separately. It was limited to the area where power lines were supplied, and the measurement using the wireless LAN interface was not suitable for outdoor use, and the measured information was not immediately notified to the manager through wired / wireless communication, so there was no way to proactively deal with the complaint.

The present invention is to overcome the above limitations of the prior art, the present invention is a ubiquitous sensor network that can monitor and manage the noise and vibration occurring in the city in real time using a ubiquitous sensor network in the central city integration center It is an object of the present invention to provide a method and apparatus for managing noise and vibration.
