Description

Technical Field

[0001] The present invention relates to the field of BIM building technology, and in particular to a design and management method for aging-friendly building spaces based on BIM technology. Background Art

[0002] BIM building model is a digital three-dimensional building model. It is not just a simple representation of the building's geometric shape, but also a comprehensive database that contains various information throughout the building's life cycle; this information covers the building's physical properties (such as material properties, component dimensions), functional characteristics (such as room usage, equipment systems), construction process (such as construction sequence, schedule) and later operation and maintenance (such as equipment maintenance cycle, facility replacement records) and other aspects.

[0003] In aging-friendly buildings, there are many complex facilities designed specifically for the elderly, such as barrier-free elevators, toilet facilities with special handrails and support devices, etc. These facilities have high requirements for details and are difficult to accurately model in BIM models. For example, details such as the size of the elevator car, the height and position of the control buttons, and the wheelchair parking area inside the barrier-free elevator may cause dimensional deviations during the construction process if the model is not accurate enough, affecting the user experience of the elderly.

[0004] For the specific characteristic units marked in the corresponding BIM building model, the model construction of the corresponding characteristic unit is generally completed directly based on the preset input data, and then the location of the corresponding unit is confirmed based on the relevant data and the specific construction of the corresponding BIM building model is completed simultaneously. However, the constructed building model does not undergo spatial characteristic analysis, which makes it impossible to determine whether the design of the corresponding model unit is reasonable. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a design and management method for aging-friendly building spaces based on BIM technology, which solves the problem that if the spatial characteristics of the building model are not analyzed, it will be impossible to determine whether the design of the corresponding model unit is reasonable.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A design and management method for aging-friendly building space based on BIM technology, comprising the following steps:

[0007] Step 1: Optimize and analyze the constructed BIM building space model. Based on the preset model database, the characteristic monomers and common monomers in the BIM building space model are confirmed and marked in turn. The specific method is as follows:

[0008] S11, based on a preset model database, in which a large number of preset model monomers are set, the monomers existing in the BIM building space model are extracted, and the extracted monomers are compared with the preset model monomers in sequence to confirm whether the identification comparison results are consistent. If they are consistent, the monomer is marked as a feature monomer or a common monomer based on the category of the preset model monomer. If they are not consistent, the comparison is continued until the category of the monomer is confirmed;

[0009] Step 2: Confirm the characteristics of the marked feature monomers in the BIM building space model, and first lock the space body to which this feature monomer belongs. Then, based on the position characteristics of the feature monomer and the space body to which it belongs, determine the spatial vector of this feature monomer, and then identify the feature interval associated with this space body from the historical completion data, identify whether the position of this feature monomer is reasonably designed, and perform relevant calibration of the feature monomer to be optimized. The specific method is as follows:

[0010] S21, based on the characteristic monomer marked in the BIM building space model, confirming the space body to which the characteristic monomer belongs, wherein the BIM building space model is composed of multiple different space bodies, and each space body has a different mark;

[0011] S22, based on the determined space body, determine the internal center point of the space body, based on the center point of each base surface of the space body, confirm the central base surface to which each base surface center point belongs, and then directly determine the center point of the central base surface, and mark the center point of the central base surface as the internal center point of the space body. When determining the center point of the base surface: generally based on the overall contour of the corresponding base surface, confirm the two-dimensional coordinates associated with different contour points in the overall contour in a two-dimensional coordinate system, and then perform mean processing on several groups of two-dimensional coordinates to confirm the corresponding mean coordinates. The point where the mean coordinate is located is the center point of the corresponding base surface, and this center point is marked as the main point;

[0012] S23, identifying a preset model monomer consistent with the feature monomer, and a preset center point exists in the preset model monomer, confirming the center point of the feature monomer based on the preset center point in the preset model monomer, and marking the center point as a secondary point;

[0013] S24, based on the spatial positions of the secondary point and the primary point, determine the spatial vector between the secondary point and the primary point, and mark the length of the spatial vector as L;

[0014] S25, identifying the associated data of the same characteristic monomer in the space body from the historical completed data, determining the lengths of the space vectors generated by the characteristic monomers and the space body from the identified sets of associated data, and then performing mean processing on the lengths of the confirmed sets of vectors to determine the length mean J;

[0015] S26, based on the determined length mean J and the preset value Y1, confirm the standard interval [J-Y1, J+Y1], and identify whether the space vector length L satisfies: L∈[J-Y1, J+Y1]. If not, it means that the position design of this feature monomer is unreasonable, and this feature monomer is marked as a feature monomer to be optimized; if it is satisfied, it means that the position design of this feature monomer is reasonable, and no processing is required;

[0016] Step 3: Confirm the characteristics of the common monomers marked in the BIM building space model, prioritize the space body to which the common monomer belongs, and then identify whether the common monomer is reasonably designed based on the spatial characteristics of the corresponding common monomer in the space body to which it belongs, and perform relevant calibration of the common monomer to be optimized. The specific method is as follows:

[0017] S31, based on the calibrated common monomer, confirm the space body to which the common monomer belongs, calibrate several base surfaces of the space body as characteristic base surfaces, and then calibrate the characteristic base surfaces that are not in contact with the common monomer as base surfaces to be processed;

[0018] S32, based on the confirmed base surface to be processed and the edge contour of the common monomer, confirm the vertical point closest to the base surface to be processed from the edge contour of the common monomer, and simultaneously confirm the vertical distance, based on the number of existing base surfaces G to be processed, the confirmed G vertical distances H k Perform numerical confirmation, where k = 1, 2, ..., G, and identify the confirmed vertical distances H k Are they all satisfied? k ≥Y2, where Y2 is the preset value. If it is satisfied, it means that the design of this common monomer is reasonable; a number of vertical distances H k Not all H are satisfied k When ≥Y2, it means that the design of this common monomer is unreasonable, and this common monomer is directly marked as a common monomer to be optimized;

[0019] Step 4: For the characteristic monomers to be optimized and the common monomers to be optimized determined in the BIM building space model, the sizes of the characteristic monomers to be optimized and the common monomers to be optimized are optimized, and the related error monomers in the optimization process are determined. If there are no error monomers, the BIM building space model is directly calibrated as a standard model and displayed directly. The specific sub-steps are as follows:

[0020] S41, based on the characteristic monomers to be optimized and the common monomers to be optimized determined in the BIM building space model, determine the model sizes of the current characteristic monomers to be optimized and the common monomers to be optimized, then identify the model sizes associated with the same type of monomers from the model database, and reduce the model sizes of the characteristic monomers to be optimized and the common monomers to be optimized, and the sizes reduced in sequence should be consistent with the model sizes associated with the same type of monomers in the model database;

[0021] S42, for the feature monomer to be optimized: in the process of reducing the model size, identify whether the space vector length L associated with the feature monomer to be optimized satisfies: L∈[J-Y1, J+Y1], and stop when the model size is reduced to the point where the space vector length L satisfies this evaluation condition, and complete the optimization process of the feature monomer to be optimized. If the feature monomer to be optimized still cannot meet this evaluation condition when it is reduced to the minimum model size, then mark the feature monomer to be optimized as an error monomer;

[0022] For the common monomer to be optimized: in the process of reducing the model size, identify several vertical distances H associated with the characteristic monomer to be optimized k Are they all satisfied? k ≥Y2, when the model size is reduced to the space vector length L that meets this evaluation condition, the optimization process of this common monomer to be optimized is completed. If the common monomer to be optimized still cannot meet this evaluation condition when it is reduced to the minimum model size, the common monomer to be optimized is marked as an error monomer;

[0023] S43. Identify whether there are erroneous monomers in the BIM building space model optimization process. If so, mark the calibrated erroneous monomers and display them synchronously; if there are no erroneous monomers in the BIM building space model, calibrate the BIM building space model as a standard model and display it.

[0024] The present invention provides a design and management method for aging-friendly building spaces based on BIM technology. Compared with the prior art, it has the following beneficial effects:

[0025] The present invention performs monomer analysis on the constructed building model, confirms the related models associated with the monomers based on the specific monomers existing in the corresponding model, and then performs feature analysis based on the confirmed related models. For the characteristic monomers with aging characteristics, spatial feature analysis is performed on them to identify whether the spatial features of the characteristic monomers are reasonably designed. For the ordinary monomers without aging characteristics, distance analysis is performed on them to identify whether the positions of the ordinary monomers are reasonably designed. In this way, the related monomers to be optimized can be quickly and effectively determined, achieving a fast and effective determination effect.

[0026] For relevant monomers with unreasonable spatial characteristics and distance characteristics, the model size is reduced to adjust the relevant monomers, so that the design of the corresponding monomers in the space is reasonable, achieving better design management effect, and enabling the corresponding BIM building space model to obtain better optimization processing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 It is a schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] First embodiment

[0030] See also Figure 1 , this application provides a design and management method for aging-friendly building space based on BIM technology, including the following steps:

[0031] Step 1: Optimize and analyze the constructed BIM building space model. Based on the preset model database, the characteristic monomers and common monomers in the BIM building space model are confirmed and marked in turn. Specifically, the so-called characteristic monomers are the handrails set in the aging-friendly building and some related monomers suitable for the elderly. The related common monomers are other monomers that do not belong to the characteristic monomers and are normal monomers set in the building model. The specific method of confirmation and marking is:

[0032] S11, based on a preset model database, in which a large number of preset model monomers are set in advance by relevant operators, the monomers existing in the BIM building space model are extracted, and the extracted monomers are compared with the preset model monomers in sequence to confirm whether the identification comparison results are consistent. If they are consistent, the monomer is marked as a feature monomer or a common monomer based on the category of the preset model monomer. If they are not consistent, the comparison is continued until the category of the monomer is confirmed;

[0033] Specifically, the monomers existing in the corresponding BIM building space model are all extracted from the corresponding model database, so they can be directly compared with the model database to directly determine the specific categories of the relevant monomers in the corresponding building space model, and to perform specific classification of characteristic monomers or common monomers;

[0034] Step 2: Confirm the features of the marked feature monomers in the BIM building space model, prioritize the space body to which the feature monomer belongs, and then determine the space vector of the feature monomer based on the position features of the feature monomer and the space body to which it belongs. Then, identify the feature interval associated with the space body from the historical completion data, identify whether the position of the feature monomer is reasonably designed, and perform relevant calibration of the feature monomer to be optimized. The specific method of identification is as follows:

[0035] S21. Based on the characteristic monomers marked in the BIM building space model, confirm the space body to which the characteristic monomers belong. The BIM building space model is composed of multiple different space bodies, and each space body has a different mark (for example, in a building model space, there are corresponding living rooms, bedrooms, etc., which have specific spaces with corresponding marks, and they belong to corresponding different space bodies);

[0036] S22, based on the determined space body, determine the internal center point of the space body, based on the center point of each base surface of the space body, confirm the central base surface to which each base surface center point belongs, and then directly determine the center point of the central base surface, and mark the center point of the central base surface as the internal center point of the space body. When determining the center point of the base surface: generally based on the overall contour of the corresponding base surface, confirm the two-dimensional coordinates associated with different contour points in the overall contour in a two-dimensional coordinate system, and then perform mean processing on several groups of two-dimensional coordinates to confirm the corresponding mean coordinates. The point where the mean coordinate is located is the center point of the corresponding base surface, and this center point is marked as the main point;

[0037] S23, identifying a preset model monomer consistent with the feature monomer, and a preset center point exists in the preset model monomer, confirming the center point of the feature monomer based on the preset center point in the preset model monomer, and marking the center point as a secondary point;

[0038] S24, based on the spatial positions of the secondary point and the primary point, determine the spatial vector between the secondary point and the primary point, and mark the length of the spatial vector as L;

[0039] S25, identifying the associated data of the same characteristic monomer in the corresponding space body from the historical completed data (for example, if there is a handrail in the corresponding space body, then directly identifying the handrail in the corresponding space body from the historical completed data, and confirming them in turn), determining the lengths of several groups of space vectors generated by several groups of characteristic monomers and the corresponding space body from the identified several groups of associated data, and then performing mean processing on the lengths of the confirmed several groups of vectors to determine the length mean J;

[0040] S26, based on the determined length mean J and the preset value Y1, where the specific value of Y1 is determined by the operator based on experience, confirm the standard interval [J-Y1, J+Y1], and identify whether the spatial vector length L satisfies: L∈[J-Y1, J+Y1]. If so, it means that the position design of this feature monomer is reasonable and no processing is required. If not, it means that the position design of this feature monomer is unreasonable, and this feature monomer is marked as a feature monomer to be optimized;

[0041] Specifically, in the actual design process, it is necessary to confirm the specific position of the corresponding feature monomer (such as the handrail position, etc.). If the corresponding feature monomer position is not designed reasonably, it will have a counterproductive effect. In the actual processing process, based on the center point of the corresponding monomer and the center point of the corresponding space, the corresponding specific space vector can be locked. The space vector has a related numerical length, and there is also a corresponding standard length in the historical completion data. Therefore, the corresponding reasonable state can be determined to conduct a comprehensive assessment and identify whether the feature monomer is reasonable. If the design is unreasonable, it needs to be optimized to achieve better optimization processing performance of the model monomer.

[0042] Step 3: Confirm the characteristics of the common monomers marked in the BIM building space model, prioritize the space body to which the common monomer belongs, and then identify whether the common monomer is reasonably designed based on the spatial characteristics of the corresponding common monomer in the space body to which it belongs, and perform relevant calibration of the common monomer to be optimized. The specific method of identification is:

[0043] S31, based on the calibrated common monomer, confirm the space body to which the common monomer belongs, calibrate several base surfaces of the space body as characteristic base surfaces, and then calibrate the characteristic base surfaces that are not in contact with the common monomer as base surfaces to be processed;

[0044] S32, based on the confirmed base surface to be processed and the edge contour of the common monomer, confirm the vertical point closest to the base surface to be processed from the edge contour of the common monomer, and simultaneously confirm the vertical distance, based on the number of existing base surfaces G to be processed, the confirmed G vertical distances H k Perform numerical confirmation, where k = 1, 2, ..., G, and identify the confirmed vertical distances H k Are they all satisfied? k ≥Y2, where Y2 is a preset value, and its specific value is determined by the operator based on experience. If it is satisfied, it means that the design of this ordinary monomer is reasonable, there are no small gaps or other situations around it, and it will not cause inconvenience to the elderly. If it is not satisfied, it means that the design of this ordinary monomer is unreasonable, and the gaps around it are small, which may easily cause inconvenience to the elderly or other situations. In this case, this ordinary monomer is directly marked as an ordinary monomer to be optimized.

[0045] Second embodiment

[0046] The first embodiment mainly performs the determination process of the corresponding monomer features. Based on the relevant feature performance of the corresponding monomer features, specific feature confirmation and calibration are performed. For such calibrated feature monomers, feature optimization needs to be performed. This embodiment mainly performs the corresponding monomer optimization process to optimize the BIM building space model.

[0047] The following steps are also included:

[0048] Step 4: For the feature monomers to be optimized and the common monomers to be optimized determined in the BIM building space model, the size of the feature monomers to be optimized and the common monomers to be optimized are optimized, and the relevant error monomers in the optimization process are determined. If there are no error monomers, the BIM building space model is directly calibrated as a standard model and displayed directly. The specific sub-steps for size optimization are:

[0049] S41, based on the characteristic monomers to be optimized and the common monomers to be optimized determined in the BIM building space model, determine the model sizes of the current characteristic monomers to be optimized and the common monomers to be optimized, and then identify the model sizes associated with the same type of monomers from the model database (that is, there are several smaller sizes in the model database), so that the model sizes of the characteristic monomers to be optimized and the common monomers to be optimized are reduced, and the sizes reduced in sequence should be consistent with the model sizes associated with the same type of monomers in the model database;

[0050] S42, for the feature monomer to be optimized: in the process of reducing the model size, identify whether the space vector length L associated with the feature monomer to be optimized satisfies: L∈[J-Y1, J+Y1], and stop when the model size is reduced to the point where the space vector length L satisfies this evaluation condition, and complete the optimization process of the feature monomer to be optimized. If the feature monomer to be optimized still cannot meet this evaluation condition when it is reduced to the minimum model size, then mark the feature monomer to be optimized as an error monomer;

[0051] For the common monomer to be optimized: in the process of reducing the model size, identify several vertical distances H associated with the characteristic monomer to be optimized k Are they all satisfied? k ≥Y2, when the model size is reduced to the space vector length L that meets this evaluation condition, the optimization process of this common monomer to be optimized is completed. If the common monomer to be optimized still cannot meet this evaluation condition when it is reduced to the minimum model size, the common monomer to be optimized is marked as an error monomer;

[0052] S43, identifying whether there are erroneous monomers in the BIM building space model optimization process, if so, marking the calibrated erroneous monomers and displaying them synchronously, if not, calibrating the BIM building space model as a standard model and displaying it;

[0053] Specifically, for the relevant monomer models set in the corresponding space, when optimizing, the corresponding models are reduced in size based on the smaller models of the same type existing in the corresponding model database. In the reduction process, when the corresponding monomer meets the corresponding evaluation conditions, it means that the characteristics of such monomers in the corresponding space are up to standard, and the corresponding optimization process is completed. If the corresponding evaluation conditions are not met, it means that the corresponding characteristic monomer is unreasonable in design, and it is necessary to calibrate the wrong monomer and display the model simultaneously to achieve better model optimization processing effect and to ensure that the model can get a better optimization processing process.
