Description

Technical Field

[0001] The present invention relates to the technical field of building digitization, and in particular to a BIM model and equipment data consistency verification method and consistency verification system. Background Art

[0002] BIM technology is the abbreviation of Building Information Modeling, which is a technology based on digital construction. It integrates all data in the process of building design, construction and operation and maintenance into a collaborative 3D model, making all stages of the construction project more efficient, accurate and reliable.

[0003] The core of BIM technology is the building information model, which not only contains the geometric shape of the building, but also includes various information such as building equipment, materials, components, pipelines, electrical systems, etc. This enables the BIM model to provide a full range of perspectives and support multiple data display and analysis methods. In the operation and maintenance management stage, BIM technology can provide a comprehensive building equipment and maintenance information management solution to help maintenance personnel improve work efficiency, accuracy and reliability.

[0004] However, the BIM model is only digital building information. It needs to be accurately matched and bound to the actual building space and equipment to meet the needs in the actual operation and maintenance process. After entering the building operation and maintenance management stage, once the equipment in the BIM model is inconsistent with the equipment in the operation and maintenance platform, it will affect the equipment management function of the platform, and there will be problems such as equipment data display errors and missing data for insufficient equipment. Due to the large number of equipment, often thousands of units, the current method can only rely on manual verification, but manual inspection has great problems in timeliness and accuracy, requires a lot of time and human resources, and is prone to errors and inaccurate results, and cannot ensure the accuracy and completeness of equipment information. Therefore, the accuracy and completeness of data initialization work in the operation and maintenance management stage are very important.

[0005] In view of this, this application is hereby filed. Summary of the invention

[0006] The first purpose of the present invention is to provide a method for checking the consistency of BIM models and equipment data, which can quickly and accurately check the consistency of equipment data in the BIM model with the equipment ledger in the actual operation and maintenance platform, greatly improving the efficiency and accuracy of data initialization in the operation and maintenance management stage, greatly reducing human errors and alleviating the manpower burden, improving the accuracy, integrity and security of platform delivery, reducing costs while also improving delivery efficiency.

[0007] The second purpose of the present invention is to provide a consistency verification system, which can quickly and accurately perform consistency verification on the equipment data in the BIM model and the equipment ledger in the actual operation and maintenance platform, greatly improving the efficiency and accuracy of data initialization in the operation and maintenance management stage, greatly reducing human errors and alleviating the manpower burden, improving the accuracy, integrity and security of platform delivery, reducing costs while also improving delivery efficiency.

[0012] S3. Verify whether the platform device data and the model device data are completely consistent and correspond to each other; if so, the consistency check is qualified; if not, the consistency check is unqualified.

[0013] Further, in S3, if the platform device location point and the model device location point are inconsistent between the platform device data and the model device data, a deep verification process is executed, and the deep verification process includes the following steps:

[0014] S'1. Construct a maximum cuboid within the spatial range of the three-dimensional model of the corresponding equipment in the BIM model of the target building, and take the maximum cuboid as the evaluation object;

[0015] S'2. Determine the volume ratio of the evaluation object to the corresponding device. If the volume ratio is greater than or equal to a first ratio threshold, use the evaluation object as a reference benchmark;

[0016] S'3. If the platform equipment position point is within the reference datum range, it is determined that the platform equipment data and the model equipment data are completely consistent and corresponding.

[0017] Further, in S'2, if the volume ratio is less than the first ratio threshold, a minimum cuboid that can completely contain the three-dimensional model of the equipment is constructed according to the three-dimensional model of the corresponding equipment in the BIM model of the target building, and the minimum cuboid is used as the evaluation object;

[0018] The evaluation object is intercepted with a plane parallel to a surface of the evaluation object, and the volume proportion of the device in the intercepted object is determined. If the volume proportion is less than the second ratio threshold, the remaining part after the interception is used as a new evaluation object and the interception operation is repeated until the volume proportion of the device in the intercepted object is always greater than or equal to the second ratio threshold. At this time, the final intercepted remaining part is used as a reference benchmark and S'3 is executed.

[0019] Furthermore, in S3, when verifying whether the platform device data and the model device data are completely consistent and corresponding, it includes: and verifying whether the platform device location point and the model device location point are consistent.

[0020] Furthermore, the BIM model and equipment data consistency verification method also includes the following steps:

[0021] S4. Generate a consistency check result report and mark the equipment that fails the consistency check in the BIM model of the target building.

[0024] The second information acquisition end is used to execute S2 in the above-mentioned BIM model and equipment data consistency verification method, and the second information acquisition end is used to communicate with the BIM model system to obtain model equipment data.

[0044] Please refer to Figure 1 , this embodiment provides a method for checking consistency between a BIM model and equipment data, the method comprising the following steps:

[0045] S1. Obtain platform equipment data from the equipment operation and maintenance management platform of the target building, where the platform equipment data includes the location points of the platform equipment. The platform equipment data refers to the relevant information of the equipment recorded in the equipment operation and maintenance management platform.

[0046] S2. Determine model equipment data according to the BIM model of the target building, where the model equipment data includes model equipment location points. The model equipment data refers to the relevant information of the equipment reflected in the BIM model of the target building.

[0047] S3. Check whether the platform device data and the model device data are completely consistent. If yes, the consistency check is qualified. If not, the consistency check is unqualified.

[0048] Specifically, in S3, verifying whether the platform device data and the model device data are completely consistent and corresponding includes: verifying whether the platform device location point and the model device location point are consistent.

[0049] The method for checking the consistency of the BIM model and equipment data also includes the step: S4, generating a consistency check result report, and marking the equipment that fails the consistency check in the BIM model of the target building.

[0050] In this way, the consistency check between the equipment operation and maintenance management platform and the actual equipment in the target building can be quickly completed during the data initialization phase of the operation and maintenance management phase, and the problem equipment can be intuitively and quickly located.

[0051] Optionally, when extracting model equipment data from the BIM model of the target building, the BIM model may be lightweight converted and converted into an offline data package to facilitate on-site verification at the target building site.

[0052] In this embodiment, in S3, if the platform device location point and the model device location point are inconsistent between the platform device data and the model device data, the deep verification process is executed. In other words, the deep verification process is also part of S3. Specifically, the deep verification process includes the following steps:

[0053] S'1. Construct the largest cuboid within the spatial range of the 3D model of the corresponding equipment in the BIM model of the target building, that is, construct the largest cuboid inside the 3D model of the equipment, which is equivalent to making the largest cuboid inside the 3D model of the equipment and inscribed with the 3D model. Take the largest cuboid as the evaluation object. In particular, when the 3D model of the equipment is spherical, the constructed largest cuboid becomes a special cuboid with equal side lengths, that is, a cube.

[0054] S'2. Determine the volume ratio of the evaluation object to the corresponding device. If the volume ratio is greater than or equal to the first ratio threshold, the evaluation object is used as a reference benchmark. The reference benchmark is essentially a spatial range. The first ratio threshold can be adjusted according to actual conditions.

[0055] S'3. If the platform device position point is within the reference datum range, that is, the platform device position point of the device is located inside or on the surface of the reference datum, it is determined that the platform device data and the model device data are completely consistent and corresponding.

[0056] Furthermore, in S'2, if the volume ratio is less than the first ratio threshold, a minimum cuboid that can completely contain the three-dimensional model of the device is constructed based on the three-dimensional model of the corresponding device in the BIM model of the target building, that is, a minimum cuboid is constructed to surround the three-dimensional model of the device, so that the three-dimensional model of the device is located in the minimum cuboid, and the three-dimensional model of the device is inscribed in the minimum cuboid. The minimum cuboid is used as the evaluation object. In particular, when the three-dimensional model of the device is spherical, the constructed minimum cuboid becomes a special cuboid with equal side lengths, that is, a cube.

[0057] like Figure 2 As shown, the evaluation object corresponding to device A is cuboid a. The cuboid a is the smallest cuboid that can contain device A.

[0058] The object to be evaluated is intercepted by a plane parallel to one surface of the object to be evaluated, such as Figure 3 As shown, the cuboid a is intercepted by plane P1, and the intercepted object is object p, as shown in Figure 4 shown.

[0059] In the intercepted object, the device corresponds to the space K1, and the overall space of the intercepted object (object p) is K2.

[0060] Determine the volume ratio of the device in the intercepted object, volume ratio = volume of space K1 / volume of space K2. If the volume ratio is less than the second ratio threshold, the remaining part after interception is used as a new evaluation object and the interception operation is repeated. The second ratio threshold can be set and adjusted according to actual needs. Among them, the "thickness" of each interception can be flexibly selected according to actual needs, that is, the unit thickness of each interception can be adjusted according to actual conditions.

[0061] When the volume proportion of the device in the intercepted object is always greater than or equal to the second ratio threshold, the remaining portion is used as a reference benchmark and S'3 is executed.

[0062] It should be noted that the plane P1 can be intercepted from both ends of the cuboid a. Since the cuboid a has multiple surfaces, the cuboid a can also be intercepted by replacing the plane parallel to the other surfaces of the cuboid a, such as Figure 5 The plane P2 and Figure 6 Plane P3 in .

[0063] When intercepting from various directions, the volume proportion of the device in the intercepted object is always greater than or equal to the second ratio threshold, and the final remaining part can be used as a reference benchmark.

[0064] Through this design, the main part of the device on its three-dimensional structure can be smoothly confirmed, which facilitates reasonable judgment of its position points, thereby completing the consistency verification of the position points of devices with irregular shapes and helping to troubleshoot problems with incorrect equipment installation positions.

[0065] This embodiment also provides a consistency verification system, which includes: a first information acquisition end, a second information acquisition end and a processing end.

[0066] The first information acquisition end is used to execute S1 in the above-mentioned BIM model and equipment data consistency verification method, and the first information acquisition end is used to communicate with the equipment operation and maintenance management platform to obtain platform equipment data.

[0067] The second information acquisition end is used to execute S2 in the above-mentioned BIM model and equipment data consistency verification method, and the second information acquisition end is used to communicate with the BIM model system to obtain model equipment data.

[0068] The first information acquisition terminal and the second information acquisition terminal are both connected to the processing terminal for communication. The processing terminal is used to execute S3 in the above-mentioned BIM model and equipment data consistency verification method.

[0069] The consistency verification system further includes: a data reporting end. The data reporting end is used to execute S4 in the above-mentioned BIM model and equipment data consistency verification method.

[0070] In addition, the data reporting end is also used to count the consistency check failure rates of different types of equipment according to the consistency check result report, and sort them in order of high and low consistency check failure rates. This allows managers to quickly understand the status of different types of equipment and to troubleshoot equipment types with high consistency check failure rates.

[0071] In summary, the BIM model and equipment data consistency verification method provided in the embodiment of the present invention can quickly and accurately perform consistency verification on the equipment data in the BIM model and the equipment ledger in the actual operation and maintenance platform, greatly improving the data initialization work efficiency and accuracy in the operation and maintenance management stage, greatly reducing human errors and reducing the manpower burden, improving the accuracy, integrity and security of platform delivery, reducing costs while also improving delivery efficiency.
