Description

[0001] The present invention relates to an IOT-BIM link apparatus and method for managing IOT-based facilities,

The present invention relates to an IOT-BIM linkage apparatus and method for managing IOT-based facilities, and more particularly, to an Internet IOT (Internet Of Things) data, which is a core technology for smart facility management, The present invention relates to an IOT-BIM linkage apparatus and method for managing IOT-based facilities that can be linked to each other.

Building Information Modeling (BIM) refers to the process of modeling a facility in virtual space, including planning, design, engineering (structure, facility, electricity, etc.), construction, maintenance and disposal in a multidimensional virtual space. BIM's building refers to the entire life cycle of the building - design, construction, operation and management, information refers to all information contained in the entire life cycle of the building, Means an integrated tool and platform that provides production, management, and publishing of all information contained in the entire life cycle.

The BIM method is a 3D-based design and modeling method that can digitize building data to create numerical data and display 3D display effects. Data of a length connecting a start point and an end point of a line other than a simple line and a surface operation is generated, and the area is data based on the closed surface. By combining the data of length and area, volume data can be obtained.

In addition, the BIM method includes information on shape information, attribute information, relationship, and topology of an object, and is excellent in analysis, service linkage, and usability. In other words, BIM expresses each property of building objects such as walls, slabs, windows, doors, roofs, stairs, etc., and recognizes each other's relations and immediately reflects the building elements to the building design. Therefore, by using BIM, it is possible to manage and utilize all the information at all stages through the compatibility and sharing of the data generated when building the building, regardless of whether the buildings to be designed are regular or irregular .

On the other hand, attention and technology development for facility management using the Internet of objects are being actively developed. However, in the past, there has been a lack of research to define data related to IOT technology, which is a key technology for smart facility management, in accordance with use cases and to link it with BIM. Therefore, based on the link between IOT and BIM, We need skills to manage.
