The method mainly determines the risk index of different areas in the heating surface according to the operating data of the boiler heating surface, and displays the areas with different risk indexes differently in the boiler model. The risk situation of the boiler heating surface is intuitively reflected, which is convenient for relevant professionals to prioritize and deal with areas with higher risk levels, improve the safety and stability of boiler operation, and avoid causing greater economic losses and safety accidents. By triggering the operation to display the operating data of the corresponding area, it is convenient for professionals to quickly and intuitively obtain the operating status of the target area and improve the efficiency of data acquisition. Although the above patent solves the problem of obtaining heating surface data, the following problems still exist in actual operation:

[0109] The power plant boiler equipment model building unit is also used for:

[0110] According to the basic size and structure of each equipment in the basic data of the equipment, use CATIA software to draw the geometric model, and add pipe connectors and support parts when drawing the geometric model;

[0132] To solve the existing technology, please refer to Figure 1 and Figure 2 , this embodiment provides the following technical solutions:

[0133] Runs the device parameter model building unit, also used to:

[0140] The sensor monitoring data is mapped to the sensor three-dimensional model, and the parameter model data is obtained after the mapping is completed.

[0141] Specifically, real-time monitoring of the installation location data of each sensor ensures the real-time and accuracy of the data, which is crucial for systems such as power plant boilers that require high monitoring and timely response. Extracting feature data (such as maximum, minimum, average, etc.) provides strong data support for subsequent fault prediction, performance evaluation and optimization. These data can be directly used to analyze the working status of the boiler heating surface, helping operators to find problems and take measures in a timely manner. A three-dimensional scanner is used to obtain three-dimensional data of the sensor and its installation location, and a three-dimensional model of the sensor is constructed through three-dimensional reconstruction technology, so that the structure of the power plant boiler heating surface and the layout of the sensor can be intuitively displayed. This visualization method greatly improves the operator's understanding and cognition of the system structure, helps to quickly locate problems and optimize the layout, and maps the sensor monitoring data to the sensor three-dimensional model to form parameter model data. This mapping not only retains the real-time and accuracy of the data, but also intuitively displays the change trend and distribution of the data in the form of a three-dimensional model. This is of great significance for understanding the working status of the boiler heating surface, evaluating its performance, and predicting potential faults.

[0142] In order to solve the problem in the prior art that the boiler equipment and the sensors corresponding to each equipment are not integrated into a more specific and relevant model, resulting in an incomplete boiler heating surface model, please refer to Figure 1 and Figure 2 , this embodiment provides the following technical solutions:

[0143] The Modeling Data Analysis Unit is also used to:

[0144] Merge parameter model data and equipment model data in CATIA software;

[0145] Before the parameter model data and the device model data are merged into a model, the installation position of each sensor in the parameter model data is confirmed;

[0146] After the installation position is confirmed, the installation position of each sensor is imported into the corresponding device in the device model data, and the parameter model data and the device model data are aligned in space;

[0147] After the spatial alignment is completed, the monitoring data in the parameter model data is mapped to the corresponding equipment in the equipment model data, and the monitoring data is associated with the corresponding equipment;

[0148] After the equipment and monitoring data are associated, a data interface is created. After the data interface is created, an equipment model for real-time monitoring data transmission is obtained, and the equipment model for real-time monitoring data transmission is marked as boiler real-time three-dimensional model data.

[0149] Use boiler real-time 3D model data to analyze boiler heating surface;

[0150] The boiler heating surface analysis includes static analysis and dynamic analysis;

[0151] Static analysis is to confirm the structural strength and thermal distribution data of each device under static conditions;

[0152] Dynamic analysis is to confirm the dynamic behavior of each sensor under operating conditions;

[0153] The static analysis data and the dynamic analysis data are analyzed for correlation, and the monitoring data of each device using the sensor is obtained based on the analysis results, and the monitoring data is marked as three-dimensional data of the boiler heating surface.

[0154] Specifically, by merging parameter model data and equipment model data in CATIA software, seamless connection from design to actual equipment is achieved, ensuring the accuracy and integrity of the model. This integration method reduces errors in data conversion and manual intervention, improves the consistency and accuracy of the model, maps and associates the monitoring data in the parameter model with specific equipment in the equipment model, and realizes the visualization of real-time monitoring data. This real-time performance not only enhances the responsiveness of the management system, but also enables operators to quickly grasp the operating status of the boiler, discover and deal with potential problems in a timely manner, and present the monitoring data and equipment model in three-dimensional form, greatly improving the intuitiveness and comprehensibility of the system. Operators can quickly understand the overall structure of the boiler and the details of the heating surface through the three-dimensional model without having deep professional knowledge, which improves work efficiency and decision-making accuracy. By performing static and dynamic analysis on the heating surface of the boiler and associating monitoring data, the system can comprehensively evaluate the operating status and performance of the boiler. This comprehensive analysis helps to discover deficiencies in equipment design and operation, and provides a basis for subsequent optimization and improvement. At the same time, marking the monitoring data as three-dimensional data of the boiler heating surface also provides a rich data source for subsequent simulation and performance prediction. Through real-time monitoring and comprehensive analysis, the system can promptly detect abnormal conditions in boiler operation and conduct early warning and diagnosis. This helps operators take quick measures to prevent the occurrence or expansion of faults and ensure the safe and stable operation of the boiler.

[0155] In order to solve the problem in the prior art that the best transmission channel is not selected for the three-dimensional data of the boiler heating surface, and the acquired data is not displayed more intuitively, thus reducing the work efficiency of the staff, please refer to Figure 1 and Figure 2 , this embodiment provides the following technical solutions:

[0156] The visualization management system of the heating surface of power plant boiler based on 3D model includes:

[0157] Model data transfer unit, used for:

[0158] When transmitting the three-dimensional data of the boiler heating surface to the management platform, the transmission channel with the fastest transmission speed is automatically selected;

[0159] Among them, the data transmission volume of the three-dimensional data of the boiler heating surface is first confirmed;

[0160] Then confirm the remaining channel capacity of the transmission channels, wherein the number of the transmission channels is not less than eight;

[0161] Select a transmission channel whose data transmission volume is less than the remaining capacity of the channel as the transmission channel for transmitting the three-dimensional data of the boiler heating surface to the management platform;

[0162] The three-dimensional data of the boiler heating surface is transmitted to the management platform for data processing.

[0163] Specifically, by automatically selecting the channel with the fastest transmission speed for data transmission, the time delay from the three-dimensional model of the boiler heating surface to the management platform is significantly reduced, and the response speed and real-time performance of the overall system are improved. This is particularly important for monitoring and management systems that require rapid response. After confirming the data transmission volume and the remaining capacity of the channel, the appropriate channel is selected for transmission, which effectively avoids channel congestion and resource waste. This dynamic resource allocation mechanism enables the system to use network resources more efficiently and reduce maintenance costs. Through the multi-channel (no less than eight) selection mechanism, even if a channel fails or performance degrades, the system can quickly switch to other available channels to ensure the continuity and stability of data transmission. This enhances the reliability and fault tolerance of the entire system. For complex three-dimensional models such as boiler heating surfaces, the amount of data is often very large. Through accurate data transmission volume confirmation and channel remaining capacity evaluation, it is ensured that large amounts of data can be efficiently and safely transmitted to the management platform, providing a solid foundation for subsequent data processing and visualization. The timeliness and accuracy of data transmission are the key to data analysis and decision making. This solution improves data transmission efficiency, allowing the management platform to obtain real-time status information of the boiler heating surface more quickly, thereby supporting faster and more accurate data analysis and decision-making processes.

[0169] Render the boiler visualization model with the sensor locations and monitoring data values ​​marked;

[0170] After rendering is completed, the three-dimensional visualization model data of the heating surface of the power plant boiler is obtained;

[0171] Finally, the 3D visualization model data is displayed on the display terminal as a 3D model.

[0172] Specifically, by visualizing the three-dimensional data of the boiler heating surface, the complex structure inside the boiler can be intuitively displayed, allowing operators and managers to clearly see every detail of the boiler. This intuitiveness greatly improves the ability to understand and judge the operating status of the boiler. The sensor position is marked in the boiler visualization model and the monitoring data value is displayed in real time, realizing real-time monitoring of the boiler operating status. This helps to discover potential problems in a timely manner, respond quickly and take measures, thereby improving the safety and stability of the system. The three-dimensional visualization model not only provides rich visual information, but also integrates real-time monitoring data. This enables decision makers to make quick judgments based on accurate and comprehensive information, optimize operating strategies, and improve overall operational efficiency. Through intuitive visualization, operators can more easily identify potential safety hazards, such as overheating areas, leakage points, etc. This helps to take timely measures to prevent safety accidents and improve the safety of the entire system.
