Description
The present invention relates to a system and method for managing physical spatial information of a home environment, and more particularly, to physical information about a physical space, a structure, and a facility of a home determined in a design / construction process of an individual or shared house. The present invention relates to a system and method for managing physical spatial information of a home environment that can be utilized as one resource in a network environment and combined with other resource information such as devices, networks, and services connected to the home network.
Home physical space refers to physical information about the building structure such as walls, columns, and floors, or the actual space and facilities that make up a house. That is, in a home environment, physical space information includes information about a structure of a building such as a wall, a pillar, or a floor or a location of a facility such as a door, a network cable, an electrical outlet, or a space such as a living room or a kitchen in a private or shared house. .
Most of the space and structure information is determined and fixed during the design and construction of the house. Therefore, if the information on the space and structure of the house in advance in terms of managing resources in the home environment can be useful in various aspects. For example, when a newly purchased device is plugged into an outlet, if the user knows in advance the information about the wall and room where the outlet is located, the device can automatically determine where it is plugged in. In addition, the cleaning robot can be effectively cleaned without a separate sensing algorithm to know the structure or size of the space to be cleaned.
One of the sources of information about the physical and spatial information of the home is the use of BIM (Building Information Model) information created during the design and construction phases of the home. BIM is a digital information model of buildings that is expressed in three dimensions to efficiently maintain a large number of information generated during the life cycle of buildings including houses. The digitized building information may include various property information related to the building as well as various facility information such as space and structure information of the building, electrical and cable wiring, gas piping, and fire fighting facilities.
In this regard, an intelligent facility management apparatus using BIM information and a method thereof are disclosed. The intelligent facility management apparatus using the BIM information may model at least one of a sensor network capable of sensing an abnormality of a building, a facility installed in a building, or a facility, and may have an abnormality based on a sensing signal received from the sensor network. Determine the information on the abnormal facility and the location of the abnormality, and included in the building based on at least one of the determined abnormal facility, the information on the abnormal location, or the BIM information of the building, and It is to determine at least one of information about the associated space in which the spatial correlation exists. However, the intelligent facility management apparatus using the BIM information is limited to determining the information on the damage space or the associated space associated with the abnormal facility.
Furthermore, since the BIM information is a huge amount of information including various material specifications and layouts used for the design and construction process of the building, it is burdensome and unnecessary to manage all of the information in the home. In other words, the information you actually need while maintaining your home is very limited and limited to some information.
Therefore, there is a need to newly define the information needed in the process of maintaining the home environment, and to define a schema for data representation. In addition, physical information about the actual space, structure, and facilities of the home, which are determined during the design and construction of the house, is utilized as a resource in the home network environment.

However, the following embodiments are provided to those skilled in the art to fully understand the present invention, and may be modified in various forms, and the scope of the present invention is limited to the embodiments described below. It doesn't happen.
The Home Resource Model is an abstract representation of objects within a home, which includes properties, relationships, and operations performed on them. There are two types of objects: resource objects and resource relation objects. Resource objects refer to units of Home Electronic System (HES) in a domain of a home environment. An object that specifies the relationship between resource objects in.
The home resource model describes home resource information and its relationships. The home resource model may be represented by a resource description schema including a resource object and a resource relationship object. The home resource model must be able to accommodate different systems and applications, and distribute management information between them. Home resource information can also be used for remote maintenance such as error diagnosis and resolution.
Home resource objects are located within the resource management process in the home environment. The resource object includes information from managed elements and may have three levels of hierarchies as shown in FIG. 1, that is, a domain, a class, and an object. Objects represent the basic units in a resource hierarchy. Resource objects have a one-to-one correspondence with objects in the real world. Resource objects are grouped into classes by their common functionality. In addition, resources are grouped into domains according to resource types such as devices, networks, services, and physical spaces. The home resource model can have multiple domains depending on the number of resources it manages. That is, in FIG. 1, the number of domains and the number of classes may be added or deleted.
The resource object may consist of common information and object information specific to a domain. Here, the common information of the resource object may include a resource identifier, a resource name, and a resource type. Here, the resource identifier is a unique identifier for identifying the object in the resource management process. This may consist of a domain ID and an object ID. The domain ID is a domain identifier to which the resource object belongs. The object ID is a unique identifier for identifying the object in the domain. The resource name means a name of a resource object and may be formed of a character string. The resource type refers to a resource type and may be expressed in hexadecimal. Resource types are created using classes and subclasses of resource objects. The structure of a resource object may be described by a BNF (Backus-Naur Form) notation.
The information on the physical space domain in the domain may include object ID, coordinates, internal relations, physical space object attribute list, and drawing file information. The object ID is a physical space object identifier and may be formed of a string combining a letter and a number. An internal relationship refers to an internal relationship with an upper class object according to an object type, and the internal relationship information distinguishes a location of a physical space object.
Hereinafter, a physical spatial information management system of a home environment according to a preferred embodiment of the present invention will be described in detail with reference to FIG. 2.
