[0043] In electromechanical installation projects, construction quality control of complex pipeline layout and equipment installation is a key link to ensure project safety and reliability. Existing quality control methods mainly include: traditional manual measurement methods, single-point scanning methods using laser radar, and digital construction management methods based on BIM models.

[0044] Traditional manual measurement method: This method relies on manual operation and uses equipment such as total stations, rangefinders or laser levels to measure and check construction quality. Its working principle is: use optical instruments to measure the spatial position of the construction point, compare the measured data with the design drawings, and determine the installation deviation.

[0045] This method has the following disadvantages: 1. Manual measurement requires point-by-point operation, which is time-consuming and labor-intensive, and its efficiency is seriously insufficient, especially in large-scale electromechanical installation projects; 2. The operator's experience and technical level will directly affect the measurement results, making it difficult to uniformly control the accuracy; 3. The data from manual measurement needs to be sorted out later, and lacks intuitive global quality feedback.

[0046] Single-point scanning method using LiDAR: This method measures the surface position of an object through laser beam reflection and generates point cloud data for subsequent analysis. Its working principle is: the LiDAR device captures the spatial coordinate information of the target point by emitting a laser beam, generates a point cloud model and performs deviation analysis with the design data.

[0047] This method has the following disadvantages: 1. Single-point laser scanning usually requires multiple scans of complex construction scenes and manual stitching of point cloud models, which is inefficient and difficult to avoid stitching errors; 2. Traditional lidar is mostly used in outdoor environments. In complex indoor pipeline construction, it is difficult to achieve efficient data collection due to blocked vision and insufficient equipment flexibility; 3. After scanning, a lot of time is required for data solution and post-processing, making it difficult to achieve real-time quality feedback during the construction process.

[0048] Digital construction management method based on BIM model: This method is a method of managing the construction process through digital 3D models, which combines design data and construction information to control the progress and quality of the project. Its working principle is to check the construction quality and generate deviation reports by comparing the BIM model with the data recorded on the construction site.

[0049] This method has the following disadvantages: 1. The BIM model is only used as a design tool and relies on external data from manual measurement or lidar scanning to update the construction status, resulting in insufficient data sources; 2. The matching accuracy of traditional BIM and on-site construction data is limited, especially in complex construction scenarios with millimeter-level accuracy requirements, it is difficult to meet high quality requirements.

[0050] Therefore, the existing quality control methods have the disadvantages of high dependence on manual labor, lack of real-time performance, and high difficulty in data integration and analysis, resulting in the efficiency and accuracy of installation project quality control being unable to meet the needs of complex electromechanical installation projects.

[0051] Based on this, see Figure 1 , the embodiment of the present application provides a method for controlling the quality of an installation project, comprising:

[0052] S1. Use 3D laser scanning equipment to collect on-site point cloud data and generate a real-scene model.

[0053] Exemplarily, a 3D laser scanning device is moved on-site to collect on-site point cloud data, and the on-site point cloud data is solved using the built-in SLAM algorithm of the 3D laser scanning device and uploaded to a data processing platform, where a real-life model of the scene is generated.

[0054] 3D laser scanning equipment can realize efficient collection of on-site point cloud data and 360° panoramic image acquisition, and supports real-time scanning feedback, reducing the risk of data omission and avoiding repeated scanning in the later stage, which greatly improves the detection speed of on-site construction, and is especially suitable for construction quality control in large-scale and complex scenes. For example, a 3D laser scanning device is equipped with two 32-line laser radar sensors, SLAM algorithm support and four high-definition cameras, which can collect 2.56 million point cloud data per second, covering a range of 70 meters, and can complete 6,000-10,000 square meters of on-site scanning per hour.

[0055] S2. Integrate and analyze the on-site real-scene model and the BIM design model to generate deviation data between the on-site real-scene model and the BIM design model.

[0056] Exemplarily, the ICP algorithm is used to perform fusion analysis between the on-site real-scene model and the BIM design model, and the deviation data is color-coded to display the size deviation range of different areas.

[0057] The ICP algorithm can achieve millimeter-level precision alignment between the on-site real-life model and the BIM design model, improving the accuracy of fusion analysis and the reliability of results. Deviation data supports detailed measurement of any component and can output standard analysis reports for reference in locating and adjusting construction quality issues.

[0058] S3. Generate a project quality rectification sheet based on the deviation data between the on-site real-life model and the BIM design model to guide construction personnel to rectify the quality of the installation project. In particular, a rectification log is formed for the rectification process. Deviation data can be used to identify construction deviations and omissions in real time, and provide rectification suggestions to the construction management team in a reasonable and well-founded manner to prevent the installation subcontracting teams from shirking responsibility during the rectification process. The rectification process also supports dynamic adjustment of construction quality, especially in complex scenarios, to provide optimization references for the layout adjustment of mechanical and electrical pipelines. The quality rectification process can be tracked and closed-loop managed through the construction log record and management platform.

[0059] During the completion acceptance phase, 3D laser scanning equipment is used to scan the entire scene, generate an on-site completion model, and conduct a final check with the BIM design model to ensure that the construction meets the design requirements. The on-site real-life model, deviation data, and on-site completion model are archived to build a project quality database, realize data management of the entire life cycle of the installation project, and provide reliable data support for subsequent operation and maintenance and asset management.

[0060] The installation engineering quality control method provided in the embodiment of the present application has the following advantages:

[0061] 1. Improved efficiency: Using 3D laser scanning equipment to collect point cloud data and generate on-site real-scene models can ensure fast and accurate point cloud data collection on site. Through real-time scanning feedback, the risk of data omission is reduced, repeated scanning in the later stage is avoided, and the construction progress is greatly improved.

[0062] 2. Improved accuracy: Through the fusion analysis of the on-site real-scene model with millimeter-level accuracy and the BIM design model, construction deviations can be discovered quickly and accurately, and deviation data between the on-site real-scene model and the BIM design model can be generated. The analysis results are highly reliable; compared with traditional manual measurement or single-point lidar scanning, the accuracy has been significantly improved.

[0063] 3. Enhanced real-time performance: The real-time scanning and data solving functions supported by the built-in SLAM algorithm enable rapid detection and feedback of deviations at the construction site. Compared with traditional single-point laser radar scanning, there is no need for post-stitching and delay analysis, and the real-time performance is significantly enhanced. Construction personnel can adjust the construction plan in time according to the real-time feedback results to avoid the accumulation of deviation problems to the acceptance stage, thereby improving the dynamic and timeliness of construction quality management.

[0064] 4. Strong adaptability to complex scenes: The 360° panoramic image acquisition of the 3D laser scanning device is combined with a powerful SLAM algorithm, enabling it to maintain efficient data acquisition capabilities in complex indoor pipeline layouts and occlusion scenes. Compared with the disadvantage of traditional laser radars that are easily affected by line of sight occlusion in complex scenes, this invention significantly improves the applicability of complex scenes.

[0065] 5. Full life cycle data management support: This application integrates point cloud data, BIM models and design drawings throughout the construction, acceptance and operation and maintenance stages to provide full life cycle data support. This not only improves the efficiency of completion acceptance, but also provides a detailed digital basis for subsequent engineering changes, asset management and maintenance. The automation and integration of data management further reduces manual intervention and improves the standardization and consistency of construction quality management.

[0066] 6. Reduce costs and resource consumption: Real-time detection and deviation feedback reduce the incidence of rework and construction errors, thereby saving manpower, materials and time costs. Efficient scanning and data processing methods reduce dependence on traditional measurement equipment and manual technology, and optimize resource allocation.
