Description

Device and method for online visualization of noise using ubiquitous-city middleware {Apparatus and method for online visualization of noise using ubiquitous-city middleware}

The present invention is part of the national research and development project, the project unique number: "10561", the research project name: "Seoul City industry-university cooperation project (2005 technology-based construction project)", the research title: "Intelligent for smart (ubiquitous) city City information convergence system development ".

The present invention relates to an apparatus and method for online visualization of noise using ubiquitous-city middleware, and more particularly, to a three-tier u-city system using ubiquitous-city middleware (hereinafter referred to as "U-city") middleware. A device and method for visualizing noise in a Tier Ubiquitous-city System.

The Act on the Construction of Ubiquitous Cities, etc. [Law No. 9763, Enforcement 2010. 3.10] refers to ubiquitous cities based on ubiquitous urban technology to improve the competitiveness and quality of life of cities. "A city that provides ubiquitous urban services anywhere, anytime, through facilities," he says.

In other words, u-city is a city that is created, managed and utilized by the convergence of information communication, construction, and urban engineering. It provides services that are internally complex but well integrated, provided by converged technology and infrastructure. The term U-City itself has been led by Korea and is spreading around the world, and the U-City sector is led by Korea. Although some countries in the world are working on high-tech city projects that emphasize some areas, our U-City name and form are rarely carried out except in Korea. On the other hand, starting in Korea a few years ago and now 50 U-Cities are in progress, it can be said to lead the world. It is still in the early stages, and efforts are being made in Korea to define all aspects of current concepts, methodologies, necessary technologies, etc. To this end, they feel a great need for research and development. This research, which is the basis of this patent, has been conducted by the Intelligent City (U-City) research group since 2005, and is a large-scale national project selected and supported by Seoul City. In its form, the world's first systematic study of U-City middleware systems and related technologies has been conducted. As of 2008, the U-city project, which has been carried out by local governments, was inconsistent in each direction and criticized about its utility. It aims to make the U-City project a core new industry that will be a driving force for the development of the country while being consistent and effective. To this end, efforts are being made to give a desirable direction.

"Ubiquitous computing started with the purpose of" so that you can get the services and information you want anytime, anywhere, any device, "and this ubiquitous computing is expected to bring revolutionary advances in IT. Another big trend these days is the convergence paradigm, and one of the most successful paradigms in convergence is the convergence of IT and other sectors. It is one of the promising convergence paradigms in which engineering is well converged, so Ubiquitous and U-City have common denominators, but U-City has many elements and features that Ubiquitous computing does not have. The city has merged with ubiquitous, construction, urban engineering, etc. By the way, this is due to the new features of convergence: in summary, the ubiquitous paradigm and the u-city paradigm have many parts in common, but many are not. Computing middleware systems are well organized.] And the various technologies for ubiquitous computing cannot be applied to U-City as they are, U-City requires U-City middleware system and U-City technology and methodology for convergence. In the U-City field, there is no research and technology related to the U-City middleware system other than this claim, and the word U-City middleware system is unfamiliar and the concept is not defined. base The three-tier U-City system technology is completely different from the existing ubiquitous middleware system technology and those based on it, and is a new technology for the convergence field called U-City. We invented U-City related technologies and applied for intellectual property rights (patents) for three-tier U-City system based on U-City middleware system.

Currently, U-City operates and manages U-City by establishing an integrated operation center using U-City platform. Such a U-City platform refers to making a single platform by physically connecting various components of U-City so that it can be managed and operated as an integrated system in an integrated operation center. different. Compared to the present U-City middleware system, it can be said to serve as an infrastructure of the processing tier on the three-tier U-City system model of the present patent. More specifically, this is different from the U-City middleware system. In the three-tier U-City system model proposed in this patent, it exists in the processing tier and serves as a connection element between the U-City middleware system and the filling tier. In recent years, the Ministry of Land, Transport and Maritime Affairs has led the emergence of an integrated u-city platform to build a larger u-city by integrating small u-city units using a u-city platform that does not yet have a unified standard. Under the management of the Korea Housing Land Corporation (LH Corporation), the integrated U-City platform development project is underway by 2010 by the UECO City Project. The integrated operation center is also required for the entire system operation in the three-tier U-City system based on the U-City middleware system proposed by this patent.

The recent development of Geographic Information System (GIS) technology has made it possible to produce noise maps. For example, the German state of Rhineland-Palatinate has released two-dimensional noise maps to the public over the Internet since 2008. The UK uses two-dimensional noise maps to focus on the assessment of noise hazards. Three-dimensional noise map is an area that is going to develop in the future of each country in the world. To date, no studies have combined noise maps with U-City middleware systems. The patent also supports both two-dimensional and three-dimensional noise maps.

The common device interface layer may support a ubiquitous sensor network (USN). The common application interface layer may have an internal data store for storing noise map data, which may have the form of a file and a database. In particular, the noise map data may have a form of a 2D image file or a 3D image file.

Therefore, the present invention has the following effects. First, in the conventional method, the noise map is made by hand by taking offline for several days or more. In the present invention, the noise mapping process is automated online in a three-tier U-City system centered on a U-City middleware system. Noise maps can be created and visualized near real time. Second, since it can be processed online as described above, it is possible to visualize by producing only the part desired by users online without making noise map in advance and storing it as an image form. third.

The real-time noise data measured at the filling tier is transmitted to the CDIL in the U-City middleware through the convergence network. The user may enter CDIL directly into the noise data received through the u-city portal in the presentation tier. The noise data is converted into a value that can be recognized by the situation recognition operation in the CCL. This value is stored in noise files and noise databases at UCCL and CAIL and used to produce noise maps with spatial information from GIS. The noise information is made into a noise map by applying it to the spatial model created considering the building and bridge information based on the GIS map. These production functions are carried out by UCCL and CAIL, and the produced noise map is for visualization. It is made of 2D or 3D image in UCCL and CAIL. The 2D noise map image or the 3D noise map image generated as described above is displayed on the user screen of the u-city portal existing in the presentation tier so that the user can view it.
