Description

Technical Field

[0001] The present invention relates to the technical field of collaborative management, and particularly to a collaborative management method and system for thermal power plant construction based on BIM technology. Background Art

[0002] The technical field of collaborative management focuses on optimizing cooperation among multiple departments or stakeholders by enhancing information transparency and work coordination. It includes shared data platforms, real-time communication tools, and integrated management software, aiming to achieve effective allocation and monitoring of resources, tasks, and responsibilities. In construction projects, collaborative management technology can facilitate communication and decision-making among project managers, contractors, suppliers, and design teams, thereby improving project time efficiency and quality control, and reducing cost and time waste.

[0003] Among them, the collaborative management method for thermal power plant construction involves using collaborative management technology to optimize the design, construction, and maintenance processes of thermal power plants. Its purpose is to ensure effective communication and coordination among participants in each stage through an integrated information system and collaboration tools, thereby accelerating the decision-making process, optimizing resource allocation, reducing risks, and improving the efficiency and quality of the entire project. Precise engineering coordination and high project management capabilities are required.

[0004] Existing technologies usually lack the ability of instant data processing and automated risk response in practical applications, resulting in delays in information sharing and decision-making processes. For example, traditional collaborative management technologies rely on periodically updated information, which is insufficient to handle rapidly changing site conditions, will delay resource reconfiguration and safety response, and increase project risks and costs. In addition, the lack of an automated risk monitoring and alarm mechanism makes the project rely on manual monitoring, which is inefficient and error-prone. These limitations are particularly obvious in high-speed and high-risk environments, increasing the likelihood of accidents and affecting the overall safety and cost-effectiveness of the project. Summary of the Invention

[0028] As a further solution of the present invention, the data deviation value is calculated according to the formula:

[0029]

[0030] where Δ represents the data deviation value, P a represents the key data value in the actual scheduling plan, P b represents the corresponding data value in the BIM model, σ a represents the standard deviation of the key data value in the actual scheduling plan, σ b represents the standard deviation of the corresponding data value in the BIM model, δ d represents the deviation degree of the daily plan, which represents the difference between the data of the daily plan execution and the planned preset value.

The automated safety monitoring and real-time alarm system enhances risk management and significantly reduces the possibility of safety accidents, not only improving work efficiency but also ensuring construction safety and quality control, with remarkable effects in improving project management efficiency.

The safety optimization analysis report includes the risk area identification result, safety incident statistical record and improvement measures.

[0064] Please refer to Figure 2 , the specific steps of S1 are as follows:

[0065] S101: Design and implement the data input interface, collect the personnel information and equipment types required for the construction of the thermal power plant, count the location data, record the safety status information, and integrate and generate the personnel and equipment information database;

[0066] The core objective of designing and implementing a data input interface is to ensure that all key data is accurately collected and organized for subsequent processing and application. First, it is necessary to determine which personnel information to collect, such as names, positions, contact information, and their relevance to equipment operation. Next, data on equipment types also needs to be classified and recorded, including equipment models, specifications, operating status, and their specific locations on the production line. The statistics of location data should be detailed to the installation location and environmental conditions of each piece of equipment. The data will be input through a user-friendly interface, and the interface design should support multiple data input methods, such as form filling, barcode scanning, or RFID tag scanning. To ensure data accuracy and integrity, the input data needs to be verified and error-checked in real time, such as using regular expressions to verify text input formats and setting required fields to prevent data omission. In addition, recording safety status information is an important step, which requires real-time monitoring of equipment operation status and recording any abnormalities or faults for timely response. All the collected information will be integrated to generate a personnel and equipment information database to support the construction and operation of thermal power plants.

[0067] S102: Use the personnel and equipment information database to analyze the required human resources and equipment quantities, evaluate the installation locations of equipment and the distribution plan of personnel, and generate the analysis results of resource allocation requirements;

[0068] Use the already integrated personnel and equipment information database to analyze in detail the types and quantities of human resources required. First, according to the scale and stage requirements of the project, calculate the approximate number of personnel needed, considering that different stages such as construction and maintenance may require different types of technical and management personnel. Next, the evaluation of equipment quantity is based on the expected production capacity and the average operating efficiency of the equipment. The evaluation of the installation location of the equipment needs to consider the layout of the factory, safety distances, and relevant environmental factors. For example, sensitive equipment should be avoided in high-temperature and humid areas. The evaluation of the personnel distribution plan needs to consider operation convenience and safety to ensure that each important position can be quickly reached. All the analysis results will be summarized to generate the analysis results of resource allocation requirements, which not only reflect the ratio of human and equipment but also consider the optimization of the layout, thus providing a scientific basis for subsequent resource allocation and project implementation.

[0069] S103: Through the analysis results of resource allocation requirements, check the accuracy of the chart data and adjust the layout, perform a visual representation of resource allocation, and output the initial resource distribution map;

[0070] Based on the results of resource allocation requirements analysis, carefully check the accuracy of the chart data. The process involves validating the original data to ensure that no errors are transmitted to the final chart. Then, adjust the layout to ensure clear display of information. The visual representation of resource allocation requires the use of advanced graphic tools such as GIS or CAD software, which can help draw detailed dynamic diagrams of equipment locations and personnel distributions. The selection and use of visualization tools depend on the functions and flexibility they can provide, such as supporting the editing of multi-layer layouts and highly customizable view options, ensuring that users can understand the configuration layout from multiple perspectives and scales. The initial resource distribution map output should not only accurately reflect the analysis results but also be easy for project managers and technical personnel to understand and use, thus ensuring the effective allocation of resources and the smooth progress of the project.

[0071] Please refer to Figure 3 , and the specific steps of S2 are as follows:

[0072] S201: Use the initial resource distribution map to conduct real-time location tracking and personnel distribution monitoring, capture and record the actual distribution status of personnel and equipment in real time, calculate the resource allocation efficiency, and generate the resource matching analysis results;

[0073] The resource allocation efficiency is calculated according to the formula:

[0074]

[0075] where M represents the resource allocation efficiency value, x i represents the position coordinate of the i-th device or person, represents the average value of all device or person position coordinates, v i represents the speed of the i-th device or person, and t i represents the time from the resource scheduling center to the demand point.

[0076] Let N = 3, representing three resource points.

[0077] Resource point 1: x1 = 2 km, v1 = 60 km / h, t1 = 0.5 h.

[0078] Resource point 2: x2 = 5 km, v2 = 30 km / h, t2 = 1 h.

[0079] Resource point 3: x3 = 8 km, v3 = 40 km / h, t3 = 0.75 h.

[0080] Calculate the average position coordinate

[0081]

[0082] Calculate the sum of position differences:

[0083]

[0084] Calculate the sum of the speed - time ratios:

[0085]

[0086] Substitute into the formula to calculate the resource allocation efficiency M:

[0087]

[0088] The results show that the obtained value of resource allocation efficiency is 0.421. This value reflects the comprehensive efficiency of the location concentration trend and speed response ability of resources. The closer the value is to 1, the more efficient the resource allocation is. While a lower value indicates location dispersion or response time delay, and further adjustment is required to improve the efficiency.

[0089] S202: Based on the results of resource matching analysis, adjust the positions of personnel and equipment, collect construction progress data in real - time through on - site feedback, synchronously update the resource allocation, and generate a record of resource allocation adjustment;

[0090] Based on the results of resource matching analysis, analyze in detail the real - time collected construction progress data. Through real - time analysis of on - site feedback, adjust the positions of personnel and equipment. First, it is necessary to update the status of personnel and equipment in each work area in real - time to ensure that each data update can reflect the latest site layout and resource allocation. The process involves real - time processing and updating of data, as well as comparative analysis with the actual on - site situation, and quickly respond to any inconsistencies or deviations found. The adjustment record will include the new positions of each resource and their corresponding operators. At the same time, a detailed report needs to be generated from the resource allocation adjustment record for management decision - making support, and finally a resource allocation adjustment record is formed to provide data support for maximizing resource utilization and optimizing project progress.

[0091] S203: Through the resource allocation adjustment record, evaluate the on - site safety status, update the scheduling plan according to the latest personnel and equipment distribution data, and generate an optimized scheduling plan;

[0092] Through the resource allocation adjustment record, evaluate the on - site safety status and perform necessary updates to the scheduling plan. First, analyze the current personnel and equipment distribution data, and optimize and adjust the scheduling plan according to the latest situation to improve safety and efficiency. Safety assessment needs to consider in detail the personnel density and equipment operation status in each area. After identifying potential safety hazards, immediately adjust the positions of personnel or equipment. The optimized scheduling plan will consider the latest work area layout and personnel safety requirements to ensure that each safety measure can be updated and implemented in a timely manner. The finally generated optimized scheduling plan will reflect the comprehensive consideration of safety and efficiency, providing a more reasonable resource distribution and operation guidance.

[0093] Please refer to Figure 4 , and the specific steps of S3 are as follows:

[0094] S301: Adopt the optimized scheduling plan, import the adjusted personnel and equipment positions and work schedules into the BIM model, update the actual positions and arrangements of each resource in real time, and generate a scheduling data synchronization model;

[0095] The key to adopting the optimized scheduling plan lies in effectively importing the adjusted personnel and equipment positions and work schedules into the BIM model, integrating the latest personnel positions and equipment data into the BIM software, ensuring that all data is up-to-date and accurate, and the real-time update function should be able to reflect every change, whether it is a small-scale personnel transfer or equipment reconfiguration. The process requires efficient data processing algorithms to reduce data synchronization latency. The update of the actual positions and arrangements of each resource needs to be strictly synchronized with the on-site situation to avoid any operation errors caused by information lag. The generated scheduling data synchronization model not only improves the accuracy of scheduling but also enhances the overall operation efficiency.

[0096] S302: Based on the scheduling data synchronization model, perform data verification, calculate the data deviation value between the data in the BIM model and the actual scheduling plan, and synchronously correct the deviation to generate a BIM model with complete verification;

[0097] The data deviation value is calculated according to the formula:

[0098]

[0099] where Δ represents the data deviation value, P a represents the key data value in the actual scheduling plan, P b represents the corresponding data value in the BIM model, σ a represents the standard deviation of the key data value in the actual scheduling plan, σ b represents the standard deviation of the corresponding data value in the BIM model, δ d represents the deviation degree of the daily plan, indicating the difference between the data of the daily plan execution and the planned preset value.

[0100] Let P a be the data of a certain key facility in the actual scheduling plan, such as the completion percentage of the project progress; P b be the data of the same facility in the BIM model. Through real-time equipment monitoring, P a is 45%, while P b calculated through the BIM model is 43%.

[0101] Furthermore, calculate the standard deviations σ a and σ bAmong the data changes over a past period, the standard deviation σ of the actually calculated scheduling plan is a 2%, while the standard deviation σ of the data changes in the BIM model is b 1.8%.

[0102] The deviation degree δ of the daily plan d represents the adjustment frequency of the plan, which is obtained from the average value of the daily changes in the actual scheduling data and is 0.5%.

[0103] Substitute the above values into the formula for calculation:

[0104]

[0105] The result shows that the data deviation between the current BIM model and the actual scheduling plan is approximately 0.4878. This value is small, indicating a high degree of consistency between the BIM model and the actual scheduling. Through this value, the BIM model can be further optimized to ensure that it is closer to the actual execution situation, thereby improving the accuracy and efficiency of project management.

[0106] S303: By verifying the complete BIM model, update all data displays of the BIM model, reveal the latest work arrangements and resource locations, and generate a synchronously updated BIM model;

[0107] The key to verifying the complete BIM model lies in updating all data displays to ensure that each data point reflects the latest work arrangements and resource locations. First, the update process requires a reliable data stream to ensure that all inputs are up-to-date and accurate. Then, the update of the BIM model should reflect any changes in the scheduling plan in real time, including personnel movements, equipment adjustments, and working hour changes. The updated BIM model needs to have an intuitive display of the work process so that both management and staff can clearly see the latest work layout. The synchronously updated model can greatly improve the response speed of engineering projects and the accuracy of resource allocation.

[0108] Please refer to Figure 5 , the specific steps of S4 are as follows:

[0109] S401: Using the synchronously updated BIM model, identify and mark the personnel entering the target risk area, and generate a risk area personnel monitoring record;

[0110] Using a BIM model with synchronous updates, the key lies in real-time monitoring of personnel entering the target risk area. First, it is necessary to ensure that the data in the BIM model is updated in real time, including the specific locations and movement paths of personnel. Then, by setting up geofencing technology, personnel entering specific risk areas can be automatically identified and marked. The process involves complex data analysis and location tracking algorithms to ensure the accuracy and real-time nature of the monitoring. The monitoring records need to list in detail the entry and exit times of each person, providing data support for safety management. The generated monitoring records of personnel in the risk area will be used for subsequent safety analysis and emergency response measures.

[0111] S402: Based on the monitoring records of personnel in the risk area, execute automatic restriction measures, perform access control locking and alarm activation, prevent and restrict unauthorized access, and generate a security restriction execution record;

[0112] Executing automatic restriction measures based on the monitoring records of personnel in the risk area is a key link, including access control locking and alarm activation. First, the system will evaluate the authorization status of each person according to the monitoring records. Unauthorized personnel will be automatically restricted from entering or staying in high-risk areas. This process relies on advanced authentication and access control systems. The access control system will be synchronized with the BIM model in real time to ensure the accuracy and timeliness of all data. The alarm system is configured at key entrances. Once unauthorized access is detected, the alarm will be activated immediately. At the same time, the system will automatically record all the execution details of the security restrictions, providing a basis for regulatory compliance and future audits. The generated security restriction execution record is a key document to ensure site safety.

[0113] S403: Through the security restriction execution record, integrate and record all triggered security events, record the alarm time, location, and personnel dynamics, and generate a real-time security alarm record;

[0114] Integrate and record all triggered security events, according to the formula Calculate the total duration S of the total number of events in the real-time security alarm record. In the formula, E i represents the severity level of the i-th event, t i represents the duration of this event, and n represents the number of security events. Considering a simple case, if there are three security events, with severity levels E = [2, 3, 1] respectively and durations t = [30, 20, 10] minutes respectively, the total number of events S = 2·30 + 3·20 + 1·10 = 130, indicating that the sum of the severity and duration of the cumulative security events within a given time period is 130 minutes.

[0115] Please refer to Figure 6 , the specific steps of S5 are as follows:

[0116] S501: Use real-time safety alert records to evaluate and compare the frequencies of safety incidents in different construction areas, collect the number of accidents occurring in the areas, identify areas with frequent accidents, and generate a list of key monitoring areas;

[0117] The key to using real-time safety alert records lies in evaluating and comparing the frequencies of safety incidents in different construction areas. First, the system needs to extract the number of accidents in each area from the records. Then, through statistical analysis, areas with frequent accidents are identified, including a detailed analysis of the types of accidents, their severity, and their specific locations. The generated list of key monitoring areas will be arranged based on the accident frequency and their potential risk levels, which not only helps the safety team focus on high-risk areas but also ensures that resources are effectively allocated to prevent future accidents, thus greatly improving the overall workplace safety.

[0118] S502: Based on the list of key monitoring areas, adjust the work plans and resource allocations for the key monitoring areas, modify the personnel deployment and equipment utilization plans, and generate an adjusted work plan;

[0119] Adjust the work plans and resource allocations for the key monitoring areas. According to the formula A new = A old + ΔA, calculate the adjusted resource allocation amount A new . In the formula, A old represents the resource amount allocated in the original work plan, and ΔA represents the resource increment adjusted based on the accident analysis results. Considering a simple example, if 10 units of safety equipment are allocated to a certain area in the original plan, and the analysis shows that the accident rate in this area has increased and 5 more units of equipment are needed, according to the formula, A new = 10 + 5 = 15 units. This indicates that resources are increased accordingly to meet the needs of areas with frequent accidents.

[0120] S503: Through the adjusted work plan, comprehensively analyze the effects of the adjustment measures, combine historical data with current improvement measures, conduct safety optimization analysis, and generate a safety optimization analysis record;

[0121] Through the adjusted work plan, comprehensively analyze the effects of the adjustment measures. First, compare historical data with current data to evaluate the improvement of safety measures. The process involves data comparison and analysis to ensure that each improvement measure can bring the expected effects. Conduct safety optimization analysis, which not only includes the evaluation of the effects of the implemented safety measures but also considers potential future improvement directions.
