System of using BIM data based on AR 1n construction site for updates building design data with smart measuring}

In the present invention, in the field of construction technology, the operator directly experiences verification and smart detection of BIM design data based on augmented reality (AR) technology at the construction site, and the part that requires modification of the design or structure is directly on the site. Regarding the system that processes the update, more specifically, the design structure of the building using augmented reality (AR) technology at the construction site (construction site) of a structure (building) such as a building, and attribute information of the material employed in each part. Real-time verification (validation, experience), smart inspection of necessary parts, and when design data update and structural change for parts that need to be supplemented such as corrections are required, directly using the data measured in the field in BIM design data. It relates to a construction site smart detection and design update system of BIM design data based on augmented reality technology that reflects in real time.

Augmented Reality (AR) technology is a technology that shows virtual content on the screen as if it actually exists. Virtual Reality (VR) technology is a technology that provides a real-like experience through the five senses, and while the actual environment linked to geographic current location information cannot be viewed, augmented reality (AR) It is a state-of-the-art technology that provides a deeper sense of reality and additional information than virtual reality (VR) because virtual information that may actually exist in the location environment is mixed (connected). As an example of augmented reality, when a specific road is illuminated with a smartphone, virtual information such as the phone number of a nearby store or building on the road, and menus sold is displayed as an image. Also, when a barcode of a product is scanned, price information, production area Information is displayed, etc. The application field is rapidly developing and developing, and there is a possibility to combine it with various technologies (functions) such as object recognition, automatic translation, voice recognition, location recognition, etc.

BIM (Building Information Modeling) design data refers to 3D design technology and is produced (occurred) throughout the life of a structure in which a building (architecture) structure is designed, constructed, completed and maintained based on a 3D information model. It is digital model information expressed so that it can be used by consistently integrating all the information, and the construction industry that has recently been enlarged and complicated by understanding and evaluating the designer's design intention and program in a short time by clarifying the designed (designed) information. It is widely applied in all technical fields of buildings in a way that solves the problem of decreasing productivity and induces rapid decision-making.

In the following description, a building and a structure, a construction site, a construction site, and a building site, or construction and construction and architecture have the same meaning, respectively, and will be selectively used appropriate to the context.

BIM design data must be constructed from the construction planning stage of the building, and in the actual construction stage, due to various variables, errors between each part such as frame, electricity, air conditioning, air conditioning, water and sewage, exterior, windows, interior, etc. In some cases, the partially changed design drawings may not be quickly reflected on the construction site, so the construction site and the BIM design data (model) need to be updated through continuous mutual comparison, and information is recycled through the BIM model, and between participants. Work efficiency should be maximized by sharing information and performing various analysis. Meanwhile, in open BIM, international standards (IFC) are used (applied) to share data with each other, regardless of what kind of software is used.

Construction errors that inevitably occur in the construction process of structures including buildings may be common, and it is necessary to quickly check these construction errors and appropriately deal with them so that the best results can be obtained. As a result of Korean Patent Application No. 10-2018-0061895 (2018. 05. 30.), there is an integrated construction error management apparatus and method using 3D scanning and BIM.

The view point matching unit 130 simultaneously reads the input 3D scanning data and the searched BIM model data to match the view point, and the integrated data generator 140 matches the 3D scanning data and the BIM model data based on the matched view point. Generates integrated data.

The construction error measurement unit 150 analyzes the integrated data to extract error data between 3D scanning data and BIM model data, and the interface unit 160 is information including visualized scanning 3D data or BIM model data and selected attribute information. Is displayed.

The prior art has the advantage of automatically deriving the data difference between the BIM model before construction and the 3D cloud of the actual structure, but the direct experience (confirmation) of each part such as the structure shape and the property information of the material at the construction site and the measured smart detection data Since it cannot be reflected in the BIM design data, there is a problem that it takes a lot of time to correct and supplement the 3D BIM design data.

In addition, there is a problem in that the actual measurement data of the site cannot be quickly reflected in the 3D BIM design data because it is not possible to directly search and make necessary corrections at the construction site using a mobile device.

Therefore, it is necessary to develop a technology that quickly searches for 3D BIM design data at the construction site using a mobile device and quickly reflects the smart detection data measured at the construction site to the 3D BIM design data.

BIM communication network transmitting through each path; Including,
The unit packet of the construction data frame is a data frame determined in a unit standard of 170 words,
The construction data frame includes an overhead data field area, a first working data field area, a second working data field area, a third working data field area, a spare data field area, an error check data field area, and an endhead data field area. It consists of 7 data field areas,
The overhead data field area is composed of 10 words, and the construction data frame is composed of the location information of the starting point where the data recording of the construction data frame starts, the data in a separate file unit, or a file unit of a specific title. The sequence (serial) number of the plurality of packet unit frames, the number of bits of data recorded in the packet unit frame, the source address information where the construction data frame is first sent, the destination address information of the node that the construction data frame passes through, Destination address information and retransmission information are included and recorded,
The first working data field area is composed of 30 words, and BIM design data to be recorded in the construction data frame by one divided unit file is recorded,
The second working data field area is composed of 30 words, and BIM design data to be recorded in the construction data frame by one divided unit file is recorded, but the same data as the data recorded in the first working data field area is recorded. Is overwritten,
The third working data field area is composed of 30 words, and an average value of the corresponding data recorded in each of the first working data field area and the second working data field area is calculated and recorded by an activated BIM operation program. ,
The spare data field area is composed of 30 words, and a part of the area that is not used by the request of the BIM operation program being actively operated is occupied and used as a buffer memory area,
The error check data field area is composed of 30 words, and when it is determined that the buffer memory area is required while the BIM operation program is recorded and operated by the active BIM operation program, the data in the spare data field area The area where is not recorded is used as the space of the buffer memory area, the address information of the current location is checked, the overhead data field area is searched to check the source address information, and the endhead data field area is searched to obtain the destination address information. Check and determine whether the address information of the current location is the same as the source address information or the destination address information, and if it is determined that the address information of the current location is the same as the source address information, the first working data field area and the second working data field The average value of the data recorded in each area is calculated and recorded in the third working data field area, and if it is determined that the address information of the current location is the same as the destination address information, the first and second working data fields are respectively The recorded data is checked for errors using the CRC check method and the Hamming code processing method, recovers the errors that have been checked, and compares the final data of each field with the data recorded in the third working data field. In this case, request to record a signal (information) for requesting retransmission in the endhead data field
The endhead data field area is composed of 10 words, the location information of the end point at which the entire data recording of the construction data frame is terminated, and the sequence (serial) number of the multiple unit frames of the entire construction data frame constituting the file unit is over. It is recorded in the same way as the head data field area. Construction of BIM design data based on augmented reality technology that includes information on the time of departure and arrival at each sending destination, waypoint, and destination, and error check data field area activation and retransmission request signal (information) based on the corresponding program request. Smart inspection and design update system used in the field.
