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.

[0033] See also Figure 1 As shown, the present invention provides a technical solution: a project quality management and monitoring system, characterized in that it includes:

[0034] Data collection and integration module, used to collect and preliminarily process data information from the construction site;

[0035] BIM model deviation monitoring module, used to build accurate BIM models of construction projects and conduct effective deviation monitoring;

[0036] The quality analysis module is used to analyze the data stored in the data storage module, including whether the quality parameters of construction materials meet the standards, the efficiency of man-hour utilization during the construction process, the equipment operation status, and whether the construction progress meets the plan;

[0037] The quality warning module is used to issue warning signals when the quality analysis module detects quality problems or potential risks. The warning signals are divided into different levels according to the severity and notify relevant personnel in various ways;

[0038] The quality assessment module is used to conduct a comprehensive assessment of the project quality based on the results of the quality analysis module, and use a scoring system to calculate the comprehensive score and give a rating.

[0039] In this embodiment, specifically: the data collection and integration module enters detailed material information through the terminal device, covering the material type, quantity, model and quality certification document elements, and the material information entry should comply with the pre-set format standard to ensure the integrity and accuracy of the information;

[0040] At the same time, the data acquisition and integration module uses sensors to collect the working hours, temperature, pressure and vibration operating parameters of the construction equipment, and performs preliminary sorting and preprocessing on the collected data to remove abnormal values ​​and erroneous data;

[0041] A special material information entry terminal is set up at the construction site. The terminal has a friendly user interface to facilitate staff to enter detailed information on materials. When entering steel bar materials, in addition to entering basic information such as type, quantity, model, etc., quality certification documents can also be associated with material information by scanning or uploading. The entry system will perform real-time format verification on the input information to ensure the correct digital format or avoid errors in filling in the material type.

[0042] For some commonly used materials, a quick entry template can be set up. The staff only needs to select the type of material, and the system will automatically fill in some default information, such as the standard model range, commonly used quality certification document format requirements, etc. The staff can then add specific quantity and other information to improve entry efficiency.

[0043] In this embodiment, specifically: the BIM model deviation monitoring module uses BIM software to construct a BIM model based on the architectural engineering design drawings and stores it in the system;

[0044] The BIM model performs denoising, contrast enhancement, brightness enhancement and filtering on the collected construction site images, substitutes them into the BIM model for detection, compares the images of the corresponding parts in the BIM model with the actual monitoring images, and determines whether there is a construction deviation based on a pre-set deviation standard;

[0045] During the BIM model creation process, the model is built according to the actual size, structural layout, material properties and other information of the building. After the model is created, multiple rounds of internal review are carried out to check whether the model has any construction errors or discrepancies with the design drawings. After the review is passed, it will be stored in the BIM model database specified by the system.

[0046] In this embodiment, specifically: the quality analysis module analyzes the quality parameters of the construction materials by comparing them with a preset material quality standard database, and the material quality standard database contains quality standard parameters of various construction materials;

[0047] The quality analysis module should analyze the efficiency of man-hour utilization during the construction process in combination with the project progress and personnel allocation to calculate the man-hour utilization rate; the analysis of the equipment operation status should be based on the normal operating parameter range of the equipment and the real-time collected data; the construction progress should be analyzed according to the pre-set construction schedule and critical path;

[0048] Combined with the project progress management system, project progress information is obtained, such as completed construction processes, planned completion time, etc. At the same time, personnel allocation information is obtained from the human resources management system, including the number of personnel in each type of work, work schedule, etc. Based on this information, the utilization rate of personnel hours is calculated.

[0049] In this embodiment, specifically: the quality analysis module analyzes the quality parameters of the construction materials by comparing them with a preset material quality standard database, and the material quality standard database contains quality standard parameters of various construction materials;

[0050] The quality analysis module should analyze the efficiency of man-hour utilization during the construction process in combination with the project progress and staffing situation to calculate the man-hour utilization rate; the analysis of the equipment operating status should be based on the normal operating parameter range of the equipment and the real-time collected data; the construction progress should be analyzed according to the pre-set construction schedule and critical path.

[0051] In this embodiment, specifically: the quality indicators set by the scoring system of the quality assessment module include the quality of construction materials, construction process specifications, construction progress compliance and construction site environmental conditions, and a corresponding weight is set for each quality indicator;

[0052] The weights of the quality assessment module are set with reference to industry standards and actual engineering conditions.

[0053] In this embodiment, specifically: the data acquisition and integration module transmits the collected and preliminarily processed data to the data storage module to provide a data source for the quality analysis module; the analysis results of the quality analysis module are transmitted to the quality warning module and the quality assessment module, the quality warning module determines whether to issue a warning signal according to the analysis results, and the quality assessment module performs a comprehensive assessment according to the analysis results;

[0054] In a specific embodiment, multiple types of sensors are installed on the construction equipment. For example, for a concrete mixer, a temperature sensor is installed to monitor the temperature of the material during the mixing process, a pressure sensor is installed to monitor the pressure in the mixing barrel, a vibration sensor is installed to detect the vibration of the equipment when it is running, and a timing sensor is installed to record the working time of the equipment; these sensors are connected to the data acquisition and integration module via wired or wireless means to ensure that the data can be transmitted in real time.

[0055] In this embodiment, specifically: the data acquisition and integration module transmits the collected and preliminarily processed data to the data storage module to provide a data source for the quality analysis module; the analysis results of the quality analysis module are transmitted to the quality warning module and the quality assessment module, the quality warning module determines whether to issue a warning signal according to the analysis results, and the quality assessment module performs a comprehensive assessment according to the analysis results;

[0056] The data acquisition and integration module performs preliminary processing on the collected equipment operation parameter data. First, a data filtering algorithm is used to remove abnormal values ​​caused by sensor failure or electromagnetic interference. In a specific implementation, if the pressure sensor suddenly transmits a pressure value far beyond the normal range, the system will determine that the data is an abnormal value and eliminate it. Then, the data is sorted, and the data collected by different sensors of the same device are integrated according to the time series to form a complete data record of the equipment operation status, and stored in a temporary buffer area, waiting to be further transmitted to the data storage module.

[0057] In this embodiment, specifically: after issuing the warning signal, the quality warning module transmits the warning level and problem description information to the quality assessment module, and the quality assessment module considers the warning situation when comprehensively assessing the project quality and adjusts the project quality rating;

[0058] The quality indicators set by the scoring system of the quality assessment module include the quality of construction materials, construction process specifications, construction progress compliance, and construction site environmental conditions; corresponding weights are set for each quality indicator with reference to industry standards (such as the unified standards for construction project quality acceptance) and the actual situation of the project (such as the importance of the project, the difficulty of construction, etc.);

[0059] In this embodiment, specifically: the quality assessment module feeds back the project quality rating result to the data acquisition and integration module, the BIM model deviation monitoring module and the quality analysis module; the data acquisition and integration module increases the acquisition frequency of key data according to the result of the quality assessment module; and the BIM model deviation monitoring module adjusts the deviation judgment standard;

[0060] According to the analysis results of the quality analysis module and the warning status of the quality warning module, the quality assessment module conducts a comprehensive assessment and rating of the project quality. The assessment results generate a quality assessment report and provide it to the owner, supervisor and other external stakeholders; for the data collection and integration module, if the project quality rating is low, the frequency of key data collection can be increased to detect problems more promptly; for the BIM model deviation monitoring module, the deviation judgment standard is adjusted according to the quality assessment results. For example, for areas with higher quality requirements, the deviation standard is appropriately tightened to improve the construction accuracy requirements.

[0061] Working principle or structural principle: Step 1, the data acquisition and integration module enters detailed material information through the terminal device, covering the material type, quantity, model and quality certification document elements, and uses sensors to collect the working time, temperature, pressure and vibration operating parameters of the construction equipment, and preliminarily organizes and preprocesses the collected data to remove abnormal values ​​and erroneous data, and then transmits the collected and preliminarily processed data to the data storage module; Step 2, the BIM model deviation monitoring module uses BIM software to build a BIM model based on the construction engineering design drawings, and stores it in the system, denoises, enhances contrast and brightness, and filters the collected construction site images, substitutes them into the BIM model for detection, compares the images of the corresponding parts in the BIM model with the actual monitoring images, and judges whether there is a construction deviation based on the pre-set deviation standard. If there is a deviation, the deviation information is transmitted to the quality analysis module;

[0062] Step three, the quality analysis module analyzes the data stored in the data storage module, including comparing the quality parameters of construction materials with the preset material quality standard database, calculating the labor time utilization efficiency in combination with the project progress and staffing situation, judging the equipment operation status based on the normal operating parameter range of the equipment and the real-time collected data, and analyzing the construction progress according to the pre-set construction schedule and critical path. If quality problems or potential risks are detected, the results are transmitted to the quality early warning module. At the same time, the influence of deviations on the project quality is judged in combination with the quality of construction materials, labor time utilization efficiency, equipment operation status, and construction progress data (if any deviation information is transmitted), and the results are transmitted to the quality early warning module and the quality assessment module;

[0063] Step 4: The quality warning module determines whether to issue a warning signal based on the results from the quality analysis module. If a warning signal is issued, it is divided into different levels according to the severity, and notifies relevant personnel, including construction management personnel, quality supervision personnel and project managers, through system interface prompts, SMS notifications and email notifications. At the same time, the warning level and problem description information are transmitted to the quality assessment module;

[0064] Step 5: The quality assessment module conducts a comprehensive assessment of the project quality based on the results of the quality analysis module, and uses a scoring system to calculate the comprehensive score and rate it. The quality indicators set by the scoring system include the quality of construction materials, construction process specifications, construction progress compliance, and construction site environmental conditions, and set corresponding weights for each quality indicator. The weight setting refers to industry standards and actual project conditions. When comprehensively assessing the project quality, the warning situation from the quality warning module is considered, and the project quality rating is adjusted. Finally, the project quality rating results are fed back to the data acquisition and integration module, the BIM model deviation monitoring module, and the quality analysis module. The data acquisition and integration module increases the collection frequency of key data based on the feedback results, and the BIM model deviation monitoring module adjusts the deviation judgment standard based on the feedback results.
