Description

Technical Field

[0001] The present invention relates to the field of construction data processing, and in particular to a construction data mapping method, device, equipment and storage medium based on BIM technology. Background Art

[0002] With the rapid development of the construction industry, construction quality control has become a key factor in ensuring project safety and efficiency. Traditional construction quality assessment methods mainly rely on manual inspection and simple intelligent equipment, which have many limitations in data collection, processing and analysis. For example, after inspectors use equipment to collect engineering data, they need to manually record and analyze it, which is not only time-consuming and labor-intensive, but also prone to human errors. Even with the use of intelligent detection equipment, they often face problems such as insufficient real-time data and complex detection processes. In recent years, although construction robots have been introduced for detection, this method requires complex preliminary planning and debugging, has a limited scope of application, and is difficult to meet the needs of diverse construction environments.

[0003] At present, the main challenge facing construction quality control is how to quickly and accurately collect engineering data in a complex construction environment, and associate this data with the digital model in real time, so as to achieve efficient quality monitoring and problem early warning. Especially in large-scale construction projects, how to accurately map the detection data collected at different locations and times to the corresponding building components, and conduct real-time analysis and feedback has become a technical problem that needs to be solved urgently. Traditional methods are difficult to effectively solve these problems. There is an information gap between the detection data and the actual components, and it is impossible to achieve real-time mapping and analysis of the data.

[0036] 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.

[0037] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] It should be clear that the described embodiments are only some embodiments of the present invention, not all 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.

[0039] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0040] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0041] The word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)", depending on the context.

[0042] The "first\second" mentioned in the embodiments is only to distinguish similar objects, and does not represent a specific order for the objects. It is understandable that the "first\second" can be interchanged with the specific order or sequence where permitted. It should be understood that the objects distinguished by "first\second" can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than those illustrated or described herein.

[0043] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] The present invention discloses a construction data mapping method, device, equipment and storage medium based on BIM technology, aiming to solve the problem that data collected at different locations and at different times cannot be mapped to corresponding components in large-scale construction projects.

[0045] See also Figure 1 and 2 The first embodiment of the present invention provides a method for mapping construction data based on BIM technology, which can be executed by a construction data mapping device (hereinafter referred to as mapping device), and in particular, by one or more processors in the mapping device, to implement at least the following steps:

[0046] S101, constructing a BIM model, and generating a corresponding coordinate domain set in the BIM model according to the type of detection equipment and the object to be detected;

[0047] In this embodiment, the mapping device may be a terminal with data processing capabilities such as a server, workstation, laptop computer, desktop computer, etc., which can communicate with the detection device in a wired or wireless manner. The mapping device may be installed with a corresponding operating system and application software, and the functions required by this embodiment are realized through the combination of the operating system and application software.

[0048] It should be noted that, taking the concrete rebound test as an example, assuming that the concrete strength of all walls of the same type on a certain floor needs to be tested. The system will first locate the specified floor in the BIM model, and then identify all wall components on that floor that meet the test requirements. For each identified wall component, the testing device will generate a corresponding coordinate domain based on the coordinate system of the BIM model.

[0049] It should be understood that this coordinate domain can be a three-dimensional space with a range slightly larger than the actual wall size. For example, if the actual size of a wall is 3 meters × 4 meters × 0.2 meters, its coordinate domain may be set to 3.2 meters × 4.2 meters × 0.4 meters. This slightly enlarged coordinate domain design can accommodate possible measurement errors and slight unevenness of the wall surface. Each coordinate domain is assigned a unique identifier and associated with the corresponding component in the BIM model. This ensures that subsequent inspection data can be accurately mapped to the correct component.

[0050] Furthermore, in this embodiment, it can also be extended to other types of detection tasks and equipment. For example, for a steel bar detector, a coordinate domain set including multiple components such as walls, beams, and columns can be generated. When a laser scanner is used for deformation monitoring, a large range of coordinate domains can be generated for the entire building exterior surface.

[0051] It should be noted that through the pre-defined coordinate domain, the inspection data can be automatically associated with the correct component. The inspectors do not need to manually record or enter component information, reducing the risk of human error and data confusion. Furthermore, all inspection data are accurately associated with the components in the BIM model, so time series analysis, trend prediction and anomaly detection can be easily performed. The inspection history and current status of any component can also be intuitively viewed through the BIM model.

[0052] S102, acquiring detection data of the building component detected by the detection device, and feeding back the coordinate information of the detection device into the coordinate domain set, wherein the detection data includes measurement information, coordinate information, and time information;

[0053] It should be noted that the detection equipment is equipped with a high-precision positioning system, which can be but not limited to UWB (Ultra-Wideband) technology or RTLS (Real-Time Location System). When inspectors use this detection equipment equipped with a positioning system to inspect building components, the equipment will collect multi-dimensional data at the same time. This data includes not only traditional measurement information, such as concrete strength values ​​or steel bar locations, but also precise three-dimensional coordinate information and timestamps.

[0054] Take the concrete rebound tester as an example. When the operator performs a test on the wall, the device automatically records the rebound value (measurement information) and captures the X, Y, and Z coordinates of the current position (coordinate information) and the specific time of the test (time information). This information will be transmitted to the test device in real time. After receiving this data, the test device immediately compares the coordinate information with the pre-defined coordinate domain set to determine the specific component to which the current test point belongs.

[0055] In this embodiment, it can provide a basis for advanced data analysis and intelligent decision-making. Specifically, through accurate spatial positioning and time information, spatiotemporal analysis of test data can be achieved. For example, the trend of concrete strength changes over time in a certain area can be tracked, or all test points that do not meet the standards can be quickly located. Accurate data mapping also supports more advanced analysis functions, such as predictive analysis of component performance and early identification of potential problems.

[0056] S103, determining the floor and the component to which the current detection point corresponds according to the coordinate information, and mapping the measurement information and time information of the current detection point to the component corresponding to the BIM model.

[0057] Specifically, in this embodiment:

[0058] Determine the floor of the current detection point according to the Z value of the coordinate information, and determine whether the coordinate information falls within the multiple coordinate domains of the floor;

[0059] If the current coordinate information falls within the coordinate domain of a single component of the floor, the measurement information and time information of the current detection point are associated with the component and mapped on the BIM model.

[0060] If the current coordinate information falls within the coordinate domain of multiple components on the floor, the Euclidean distance from the detection point to the center point of the coordinate domain of each component is calculated, and the ratio of the Euclidean distance to the distance from the center point to the corner point of the rectangular coordinate domain is calculated, and the component with the smallest ratio is selected, and the measurement information and time information of the current detection point are associated with the component with the smallest ratio, and mapped on the BIM model.

[0061] Please combine Figure 3First, determine whether the coordinate information falls within the coordinate domain of multiple components. The determination method is (X min <X i <X max ), (Y min <Y i <Y max ), where (X min ,Y min ), (X max ,Y max ) are the lower left corner coordinates and the upper right corner coordinates of the rectangular coordinate domain. When the coordinate information only falls within the coordinate domain of a single component, the corresponding detection data can be directly fed back to the corresponding component model;

[0062] In some complex situations, such as when the detection point is located at the junction of multiple components, or when the coordinate information falls into multiple coordinate domains at the same time due to measurement errors, the detection equipment will start a more complex judgment logic, that is, calculate the distance from the detection point to the center point of each component coordinate domain (X j ,Y j ) is expressed as:

[0063]

[0064] Furthermore, we calculate d i The ratio of the value to the distance from the center point to the corner point of the rectangular coordinate domain P i , whose expression is:

[0065]

[0066] According to the value of P, it is determined that the probability of the detection point falling within the coordinate domain of the component is the highest. Here, P is selected. i The component with the smallest value. After the position determination is completed, the system will accurately map the detection data to the corresponding position of the digital twin model (BIM model). This embodiment can be extended to various complex building structures and detection scenarios. For example, when detecting the exterior wall of a high-rise building, even if the detection equipment is slightly offset, the system can accurately determine which floor and which wall the data belongs to. When detecting complex steel structures, even if multiple components are closely connected in space, the system can still accurately distinguish the specific component to which each detection point belongs.

[0067] In a possible embodiment of the present invention, the constructing of the BIM model, after generating a corresponding coordinate domain set according to the detection equipment type and the object to be detected in the BIM model, further comprises:

[0068] According to the error of the positioning device inside the detection equipment, multiple coordinate domain ranges are set for each object to be detected.

[0069] Please combine Figure 4 In this embodiment, the detection device first generates a basic coordinate domain according to the geometric information of each component in the BIM model, and its rectangular coordinate domain set (Q1, Q2, Q3, ..., Q n Then, based on the known error range of the positioning device inside the detection equipment, the system will expand outward on the basis of this basic coordinate domain to form multiple nested coordinate domain ranges, forming multiple coordinate domains Q i1 , Q i2 , Q i3 Etc. For example, for a wall, the system might generate three nested rectangular coordinate domains: an inner domain that matches the exact dimensions of the wall, a slightly larger intermediate domain, and an outer domain that takes into account the maximum possible error.

[0070] In a possible embodiment of the present invention, it also includes: analyzing and generating a construction quality assessment result based on the detection data mapped on the BIM model.

[0071] The system first performs multi-dimensional statistical analysis on the inspection data mapped to the BIM model. This includes but is not limited to time series analysis, spatial distribution analysis, and comparative analysis with design standards. For example, for concrete strength data, the system can analyze its distribution in different floors and different component types, and identify areas or components with abnormal strength. For steel bar cover thickness data, the system can generate a thickness distribution heat map to intuitively display the changing trend of the cover thickness in the entire building.

[0072] The testing equipment will also automatically compare the test results with the design requirements in combination with the design information in the BIM model, and quickly identify unqualified items. Furthermore, through machine learning algorithms, the testing equipment can identify potential quality problem patterns. For example, by analyzing historical data from multiple projects, the system can predict quality problems that may be caused by certain construction processes or material combinations, so that preventive measures can be taken in advance.
