Description

The present invention relates to an asbestos three-dimensional map generation system, and in particular, a specific location where asbestos survey or analysis data of a target structure is acquired and an asbestos three-dimensional map of a target structure that can refer to the asbestos survey or analysis data of that location. The present invention relates to an asbestos three-dimensional map generation system that generates maps.

Asbestos has been extensively used in building structures in the past because of its excellent thermal properties such as heat resistance and heat insulation, as well as its stable and favorable electrical properties such as insulation. However, asbestos fibers are extremely thin, and it became clear that many health hazards such as pulmonary fibrosis and lung cancer occurred due to inhalation of asbestos dust by workers who handled asbestos. Many laws, including a ban on the use of asbestos, ban the use of asbestos and restrict its handling, and it is no longer used in new building structures.

However, many existing architectural structures that were built in the past contain asbestos, and it is said that the number of such structures is in the millions. Since dust containing asbestos is generated when such building structures containing asbestos are dismantled, many regulations have been established to prevent health hazards to workers.
Regulations on asbestos are expected to be further tightened in the future, and it is being considered to make it obligatory to conduct preliminary surveys before demolition or renovation of building structures and report the results. For contractors who dismantle or repair building structures, regardless of the obligation to report, it is important to know in advance where and how much asbestos is contained in the target structure. , is an essential need to ensure the safety of workers.

At present, preliminary surveys of building structures to be demolished or refurbished (hereafter referred to as “target structures”) are conducted by individual sample collection by the demolition or refurbishment contractor and requesting analysis from an analysis agency. It is In the case of a large target structure such as a building, analysis samples are collected at multiple locations, and the analysis results are provided individually by the analysis organization. Therefore, when dismantling such a large target structure, the site where the sample was taken and the analysis data are compared with the design data of the target structure to identify the area containing asbestos, and the workers who dismantle and repair should be organized in a way that is easy to understand and can be referred to at any time. If the analysis data can be arranged in this way, it will be possible to effectively use it for creating reports. However, at present, the only thing that can be done is to describe the target structure in a two-dimensional structural drawing, which is difficult to understand and is not user-friendly.

Patent Literature 1 discloses a device that detects whether or not waste contains asbestos based on the images obtained by photographing waste on-site at the site of demolition of an existing building without requesting an analysis agency for analysis. and methods are disclosed. According to the invention described in Patent Document 1, image data of a detection target photographed through a near-infrared spectral filter that passes near-infrared light of a predetermined wavelength is used, and the detection target contains asbestos on the spot. can determine whether or not

However, in large target structures such as buildings and factory plants, it is necessary to determine the presence or absence of asbestos at multiple points. Japanese Patent Laid-Open No. 2002-100001 does not describe whether to convey information in an easy-to-understand manner.
Aggregate the analysis data of asbestos for each specific part obtained in preliminary surveys before demolition or renovation of building structures including plants, etc., and determine which areas of the target structure contain asbestos and how much asbestos is contained. It is desired to realize a system that can generate and provide three-dimensional data that is visually easy to understand and can be easily referred to.

FIG. 1 is a block diagram schematically showing the configuration of an asbestos three-dimensional map generation system according to an embodiment of the present invention.

Referring to FIG. 1, an asbestos three-dimensional map generation system 1 according to an embodiment of the present invention manages asbestos content information of a target structure for repair or demolition work, and outputs it as a visually easy-to-understand asbestos three-dimensional map. An information management server 10, a worker terminal 20 for inputting data such as surveyed or analyzed points of the target structure, and a user terminal 30 for acquiring surveyed or analyzed data of the target structure from the information management server 10 via the network 50. have

Asbestos, which was often used in building structures in the past, has been found to be harmful to the human body, and its use is now regulated. Many of them still exist today in various forms such as plants. When such building structures are repaired or dismantled, asbestos scatters and poses a health hazard to workers.

The asbestos three-dimensional map generation system 1 according to the embodiment of the present invention saves and manages survey or analysis data related to asbestos of a target structure to be subjected to real estate appraisal, renovation or demolition work, After generating 3D structural data of the target structure based on basic dimensional data such as actual dimensional measurements at the site, specific points of the target structure from which the saved survey or analysis data was collected and the 3D structural data It is a system that generates and outputs an asbestos three-dimensional map in which asbestos survey or analysis data for specific locations or specific locations can be referenced.

The output 3D map of asbestos is provided on a web page so that it can be viewed from different perspectives. Many users, such as administrators of structures, can easily view where and how much asbestos is contained in the target structure at any time via the user terminal 30 .

Each component of the information management server 10, the operator terminal 20, and the user terminal 30 will be described in order below.
The information management server 10 includes a control unit 11 , an input/output unit 12 , a storage unit 13 , a display unit 14 , a three-dimensional structure data generation unit 15 , a survey/analysis data management unit 16 and a three-dimensional map generation unit 17 .

The three-dimensional structural data generation unit 15 generates three-dimensional structural data of the target structure based on basic dimension data such as design drawings of the target structure and actual dimension values measured on site.
If a design drawing of the target structure or a repair drawing based on the design drawing remains, the 3D structure data generation unit 15 generates 3D structure data from the input 2D data of the design drawing or repair drawing. When generating 3D structural data from 2D data, for example, after reading the 2D data, the front view, rear view, and left and right side views of the target structure are drawn vertically so that they become three-dimensional, and then the plane The exterior walls are constructed by combining them in accordance with the figure. By combining this with the interior layout diagram for each floor, the interior walls and the like are constructed three-dimensionally and generated. In addition, if the target structure has a complex shape and there are drawings from multiple directions, each drawing will be extruded to make it three-dimensional so that it has depth, then overlap each other, and the contour lines of the overlapping parts will be drawn. may be extracted to obtain the outline.

If the design drawing of the target structure does not exist, or if the structure has been repeatedly repaired and has changed significantly from the structure at the design stage, we will use a three-dimensional laser scanner, etc., to measure the dimensions of the structure on site. Three-dimensional structural data of the target structure is generated using the measured values as basic dimension data.

If the design drawing or repair drawing contains information such as the material of the member used and the model name in addition to the drawing data, the 3D structure data generation unit 15 uses this information as additional information of the generated 3D structure data. It is stored in the storage unit 13 together with the three-dimensional structure data. The additional information includes annotations such as "insulating material is used" and descriptions of processing methods such as "blasting".

In one embodiment, if there is additional information, the 3D structure data generator 15 incorporates it into the 3D structure data to generate 3D structure data with additional information. The additional information may be collectively displayed in the form of an annotation, or may be displayed in the three-dimensional structure data so as to be associated with the area to which the additional information relates.

Even if the design drawings of the target structure do not exist and the dimensions are measured on-site, if information such as the materials and model names of the members used can be obtained on-site, this information can be used as the basic dimension data for the actual measurements. is stored in the storage unit 13 together with the three-dimensional structure data as additional information of the three-dimensional structure data generated as .

In addition, if the time of construction or renovation of the target structure is known, it is desirable to include this time in the additional information. This is because the standards for asbestos regulations that are applied differ depending on the time of construction or renovation, so it is possible to judge the possibility of containing asbestos from the standards that are applied at the time of construction or renovation. Therefore, when the construction or renovation period of the target structure is known, the 3D structure data generation unit 15 configures the 3D structure data so that it is possible to identify which part of the 3D structure data was constructed and when. .

The investigation/analysis data management unit 16 saves and manages asbestos investigation or analysis data for each specific portion of the target structure. A specific location is a location where an asbestos investigation or analysis was conducted, and in particular, when an analysis is conducted to investigate the asbestos content rate, it is a location where a sample for analysis was collected. Investigation data is the data obtained by investigating the possibility of asbestos content by visually observing the appearance and examining the type name and material information displayed on the materials used. This is the data that can be obtained by collecting samples for analysis at the site and requesting an analysis agency when it is not possible to grasp it. Either one of the survey and analysis may be conducted, or both may be used.

As the scale of the target structure increases, surveys and analyzes at multiple locations are required. If there is a mistake in correspondence between the place where the survey or analysis was performed and the survey data or analysis data at that time, for example, the area containing asbestos may be repaired or dismantled without taking dust prevention measures. There is a risk of health hazards to workers such as
Therefore, in the embodiment, the survey/analysis data management unit 16 associates a unique identification ID with each specific location, and stores survey data and analysis data in the storage unit 13 in association with the corresponding identification ID of the specific location. .

Depending on the embodiment, the specific location is selected in advance by referring to the three-dimensional structure data generated by the three-dimensional structure data generation unit 15 and its additional information, and the target is the person in charge who conducts the survey or collects the analysis sample. You may go to the site of the structure and collect the survey or analysis sample according to the specific points selected in advance, or the person in charge who goes to the site of the target structure to conduct the survey or collect the analysis sample A specific location may be selected depending on the situation.

When conducting surveys or analyzes after selecting specific locations in advance, that is, when using 3D structure data as survey/analysis plan drawings, an identification ID for each specific location is issued at the time of selecting specific locations in advance. Alternatively, the identification ID may be issued at the time when the person in charge of surveying or collecting the analysis sample actually surveys or collects the analysis sample at a preselected specific location.

In one embodiment, in either case, the person in charge of collecting the survey or analysis sample carries the operator terminal 20 that can communicate with the information management server 10 via the network 50, and actually collects the survey or analysis sample. The specific location where the sampling was performed is photographed, and the acquired image data is transmitted to the information management server 10 . The information management server 10 stores the received image data of the specific location in association with the identification ID of the specific location. This improves the certainty of checking the specific location on site.

When surveying or collecting an analysis sample without selecting a specific location in advance, in one embodiment, the specific location where the person in charge has surveyed or collected an analysis sample is displayed on the worker terminal 20 carried by the operator so that the location can be known. The information is input and transmitted to the information management server 10. The information management server 10 issues a unique identification ID for the received information on the specific location, and stores the information on the specific location in association with the issued identification ID. At this time, the worker terminal 20 takes an image of a specific location, and the image data is also attached.

The information on the specific location may be entered in words such as "2nd floor, center of the wall beside the first staircase". The information is received by the operator terminal 20, is created by designating the position on the received three-dimensional structure data, and this information is transmitted to the information management server 10 and stored. Further, in the case where the worker terminal 20 is provided with detection means for position information, altitude information, azimuth information, etc., the position information, altitude information, Orientation information may be obtained and used as the information of the specific location.

When surveying the target structure, the person in charge inputs survey results into the worker terminal 20 for each specific location and transmits the survey results to the information management server 10 . In the information management server 10 , the investigation/analysis data management unit 16 associates each identification ID of the corresponding specific location and saves them in the storage unit 13 .
When analyzing a target structure, the person in charge asks an analysis agency to analyze the asbestos by associating the collected analysis sample with the specific location where the sample was collected. The analysis results are input to the information management server 10 as data for each specific location, and the survey/analysis data management unit 16 stores the input data in the storage unit 13 in association with the identification ID of each specific location. do.
When there are a plurality of target structures, the survey/analysis data management unit 16 issues a unique structure ID for each target structure, and manages the survey or analysis data for each target structure so that it can be referred to.

The three-dimensional map generating unit 17 associates the three-dimensional structure data of the target structure with the specific locations, and generates an asbestos three-dimensional map with which asbestos investigation or analysis data for the specific locations or for each specific location can be referenced.
The three-dimensional map of asbestos generated by the three-dimensional map generator 17 is provided to the user terminal 30 so that it can be browsed from a different viewpoint on the web page. Therefore, the user can, for example, click on a point on the asbestos three-dimensional map and move it in an arbitrary direction while clicking on it with a mouse or the like, and browse the asbestos three-dimensional map image rotated by an angle corresponding to the amount of movement in that direction. .

In the embodiment, when an asbestos three-dimensional map that allows specific locations to be referenced is provided, when the user selects a specific location in the asbestos three-dimensional map, the three-dimensional map generation unit 17 generates an asbestos map of the selected specific location. Provide research or analytical data. In one embodiment, when the number of specific locations of the target structure is small and the amount of information in the survey or analysis data is small, the three-dimensional map generation unit 17 generates the position of the specific location on the asbestos three-dimensional map and the survey of the specific location. Alternatively, a three-dimensional map of asbestos is generated so that the analysis data can be viewed at the same time.

In addition, the three-dimensional map generation unit 17 identifies an equivalent area having an asbestos content equivalent to that of the specific location based on at least one of the design data, renovation data, and survey data of the target structure, and Distinguishably display equivalence areas on the map. In the case of surveys, survey data on the presence or absence of asbestos can be summarized as data for areas based on the conditions of materials used. I don't know if it's representative of the area. Therefore, based on at least one of the design data, reconstruction data, and survey data of the target structure, the three-dimensional map generation unit 17 selects an area that is considered to have the same material as the specific location from which the analysis sample was acquired, Identify equivalent areas with asbestos content. As a result, when carrying out construction work in an equivalent area, the worker can refer to the asbestos three-dimensional map, recognize the area as having the same asbestos content as the specific location, and take appropriate dust prevention measures.

In addition, even if materials of the same quality are used, the standards for asbestos regulations that are applied differ depending on when the material was manufactured or when it was used for repairs, etc., and the assumed asbestos content rate may differ. There is Therefore, in the embodiment, when the timing of repair or the like is included as additional information of the three-dimensional structure data, the equivalent area is specified in consideration of this timing. In one embodiment, when the standards for asbestos regulations are changed and the corresponding asbestos regulation values are stored as a database, and when the additional information includes the timing of repairs, etc., the possibility or assumption of asbestos content is based on this database. It refers to the maximum content rate that can be used to identify the equivalent area.

Furthermore, the three-dimensional map generation unit 17 determines whether asbestos is present in the target structure based on at least one of the asbestos analysis data for each specific location of the target structure, the design data of the target structure, the reconstruction data, and the survey data. When an area containing asbestos and an area not containing asbestos coexist, the two areas are displayed in a distinguishable manner on the three-dimensional map of asbestos.
Depending on the user, information on whether or not the target structure contains asbestos is requested without obtaining the asbestos content. For example, this is the case where the value of a target structure is determined by real estate appraisal or the like. In the case of large-scale facilities such as plants, if the target structure contains asbestos or not, and if so, which facilities contain asbestos, the scope of repair or demolition work can be specified. etc. is easy to use. Therefore, the three-dimensional map generation unit 17 generates and provides a three-dimensional asbestos map that allows easy identification of areas containing asbestos and areas not containing asbestos.

Depending on the embodiment, instead of determining whether or not asbestos is contained, based on the latest asbestos regulation standards, areas are divided according to whether the asbestos content exceeds the regulation value or not, and the area is classified as asbestos 3 It may be displayed as a dimensional map.

If design drawings or repair drawings cannot be obtained, actual dimensions are measured on-site using a three-dimensional laser scanner, etc., and these measured values are entered as basic dimension data.

Next, at step S105, it is determined whether or not there is additional information for the input basic dimension data. When it is found in advance that a material that is likely to contain asbestos is being used through on-site dimensional measurements, etc., and additional information is input and registered along with the basic dimensional data, the information management server 10 can be determined by the presence or absence of registered additional information. If the additional information is limited to descriptions such as annotations in the design drawings and repair drawings, the operator may decide whether to adopt or not based on the read data of the drawings.

If there is additional information, the information management server 10 generates three-dimensional structure data with additional information from the basic dimension data and the additional information (step S110). When the additional information is registered as a text file separately from the basic dimension data, the information management server 10 extracts the text of the additional information from the saved text file and adds it to the three-dimensional structure data like a text box. may When the area related to the additional information is clear, the additional information is added to the three-dimensional structure data in association with, for example, speech balloon data so that the area related to the additional information can be identified upon receiving an input from the operator.

At step S115, the specific location where the target structure was surveyed or the analysis sample was collected is input. If specific locations can be selected in advance by referring to the three-dimensional structure data with additional information, the operator sequentially designates specific locations on the three-dimensional structure data with additional information, and the information management server 10 stores the designated locations as additional information. It is stored in association with the attached three-dimensional structure data. At this time, the information management server 10 issues a unique identification ID for each specific location, associates the identification ID with the designated position, and stores them.

If the specific location cannot be clarified unless the situation is actually observed at the site of the target structure, the information management server 10 uses the operator terminal 20 carried by the person in charge of surveying the target structure or collecting analysis samples. receives information indicating the position of the specific location from, issues a unique identification ID for each specific location, associates the identification ID with the received information indicating the location of the specific location, and stores the information.

Then, at step S120, survey or analysis data for each specific location is entered. The survey data may be input by receiving the survey data input to the worker terminal 20 by the person in charge of the survey, or may be directly input to the information management server 10 by summarizing the survey results at the site. . On the other hand, the analysis data can be input by receiving the electronic data of the analysis results sent from the terminal of the analysis institution that requested the analysis. The operator may input based on the document. The input survey or analysis data is stored in the storage unit 13 in association with the identification ID for each specific location.

The stored survey or analysis data is not limited to a specific location, and if an area equivalent to a specific location spreads out or another area exists, by using it as representative data including the equivalent area, it is possible to reduce the cost individually. It is possible to effectively utilize the analysis results that require Therefore, in step S125, the information management server 10 selects an area that is considered to have the same material as the specific location from which the analysis sample was acquired, based on at least one of the design data, reconstruction data, and survey data of the target structure. Equivalent areas with the same asbestos content as

Finally, the information management server 10 incorporates the saved specific locations and the investigation or analysis data of the specific locations into the three-dimensional structural data with additional information generated in step S110, and the asbestos investigation or analysis data for the specific locations or for each specific location. generates a referable three-dimensional map of asbestos (step S130). In one embodiment, the asbestos three-dimensional map also identifiably displays the equivalent areas identified in step S125. In addition, based on at least one of asbestos analysis data for each specific part of the target structure, design data, reconstruction data, and survey data of the target structure, areas that contain asbestos and areas that do not contain asbestos in the target structure coexist, the two areas may be displayed on the asbestos three-dimensional map so as to be identifiable.
As described above, the asbestos three-dimensional map according to the embodiment has various display forms, and these display forms may be provided to the user so that the display form can be selected on the Web page.

Returning to step S105, if there is no additional information in the basic dimension data of the target structure, that is, if there is only shape information, the information management server 10 generates three-dimensional structural data based on the basic dimension data (step S135). .
Since it is difficult to select a specific location when there is no additional information, the information management server 10 receives the information indicating the position of the specific location transmitted from the worker terminal 20 in step S140, is issued and stored in association with information indicating the position of the specific location.

Further, survey or analysis data for each specific location is entered (step S145). Details at this time are the same as the input method described in step S120.
Finally, the information management server 10 incorporates the saved specific locations and the investigation or analysis data of the specific locations into the three-dimensional structure data generated in step S135, and the asbestos investigation or analysis data of the specific locations or the specific locations is referred to. A three-dimensional map of possible asbestos is generated (step S150).
