In recent years, power plants have gradually adopted IoT technology to achieve panoramic data management, including equipment status monitoring, operating parameter collection, and maintenance record management. Traditional power plant management mainly relies on manual inspections and regular maintenance, which is not only time-consuming and labor-intensive, but also difficult to grasp the operating status and potential failures of equipment in real time. With the development of big data analysis, cloud computing, and three-dimensional visualization technology, the panoramic data management method of power plants based on IoT has gradually become a research hotspot, aiming to achieve full life cycle management and fault prediction of equipment through real-time data collection and intelligent analysis.

[0003] Although the Internet of Things technology has been applied to power plant management to a certain extent, there are still many shortcomings in the existing technology.

Secondly, the existing power plant management system mostly adopts a two-dimensional graphical interface, the information display is not intuitive enough, it is difficult to fully reflect the operating status and historical data of the equipment, and limits the decision-making efficiency of managers. Furthermore, the current fault diagnosis and prediction methods are relatively simple, usually relying on simple threshold judgment or basic statistical analysis, and cannot make full use of complex data features for accurate prediction. In addition, the technical integration of the existing system in data fusion and three-dimensional visualization is not high, and it is difficult to achieve efficient fusion and intuitive display of multi-dimensional data.

[0031] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings required for use in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0033] Figure 2 A schematic diagram of modules of a power plant panoramic data management system based on Internet of Things technology provided in the third embodiment of the present invention. DETAILED DESCRIPTION

[0034] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0035] Example 1, reference Figure 1 , which is an embodiment of the present invention, provides a power plant panoramic data management method based on Internet of Things technology, including:

[0036] S1: Obtain equipment file information and establish equipment basic information database.

[0037] Furthermore, obtaining equipment archival information and establishing an equipment basic information database involves collecting basic information about the equipment, including equipment specifications, models, installation locations in the electric field, and manufacturer information.

[0038] Record the equipment's maintenance records, inspection records and servicing records, including the date, content and results of each maintenance.

[0039] The collected data is stored in a database and labeled.

[0040] It should be noted that collecting equipment data includes using Internet of Things technology to collect equipment operation data in real time through sensors, including temperature, pressure, vibration, sound, and images.

[0041] Temperature and pressure are intermittently collected data. Although they are affected by weather factors, such influences can be easily removed based on meteorological data. Therefore, no noise reduction processing is required and only synchronization with the image is required.

[0042] Vibration and sound are also intermittently collected data. However, unlike temperature and pressure, these two types of data are easily affected. For example, the falling of objects or the voices of maintenance personnel can cause inaccurate data. Therefore, noise reduction processing is required and some data needs to be eliminated. Therefore, data supplementation is required first.

[0043] Image data is continuously acquired through the camera, so there is basically no need for excessive processing.

[0044] The collected vibration and sound data are denoised and the data is completed using the interpolation method based on the logistic function, which is expressed as:

[0045]

[0046] Among them, D raw(t) represents the raw sensor data collected at time t, μ noise represents the noise mean, e -αt represents the exponential decay factor, α is the decay coefficient, D missing,i represents the i-th missing data point, β and γ: are interpolation parameters that control the smoothness and position offset of the filled data.

[0047] S2: Collect equipment data, perform preprocessing, and implement three-dimensional visualization of the equipment data.

[0048] Furthermore, the three-dimensional visualization of the equipment data includes time synchronization of the processed vibration and sound data excluding the difference data and the temperature, pressure and image data, which is expressed as:

[0049]

[0050] Among them, D synced (t) is the data after time synchronization, α is the time attenuation coefficient, D k For the collected data.

[0051] It should be noted that the three-dimensional visualization of equipment data also includes performing difference processing again, supplementing and smoothing the temperature and pressure data, and performing time synchronization processing on the interpolated data, which can be expressed as:

[0052]

[0053] Among them, D interpolated (t) is the interpolated data, D synced,k is the kth data point, β and γ are interpolation parameters, N is the number of data points, and three-dimensional spatial imaging is performed after the data is processed.

[0054] It should also be noted that three-dimensional spatial imaging includes inputting the pre-processed data into the three-dimensional graphics library OpenGL, controlling the display effect of the data in three-dimensional space by modulating the depth, angular frequency and phase, rendering the generated three-dimensional model, and displaying the real-time status of the device, which is expressed as:

[0055]

[0056] Among them, δ is the modulation depth, ω is the angular frequency, and φ is the phase. The equipment data after denoising and interpolation processing is input into OpenGL. By inputting high-quality pre-processed data, the accuracy and reliability of the three-dimensional model are ensured. High-quality data input can significantly improve the display effect of three-dimensional images, reduce errors and noise interference, and make the real-time status display of power plant equipment clearer and more accurate, which is convenient for monitoring and decision-making. The modulation depth is used to adjust the contrast and detail display of the image, and the angular frequency and phase are used to control the time axis changes of the data, making the dynamic data display smoother and continuous. It enables managers to observe changes in equipment status in real time, discover and deal with potential problems in a timely manner,

[0057] S3: Check the status and maintenance requirements of the equipment.

[0058] Furthermore, the status and maintenance requirements of the detection equipment include setting the color of the three-dimensional model, which is green under normal conditions and red under fault conditions. The collected data is statistically analyzed and the average, maximum and minimum indicators are obtained based on the expert evaluation method. When the data is not within the indicator range or deviates from the average value for more than half of the time under operating conditions, it is marked as yellow. When the model shows red, it is considered that the equipment is in a state of waiting for maintenance, and the basic information of the equipment and the maintenance record of the equipment are called up and displayed next to the equipment, and the equipment is shut down for maintenance. When the model shows yellow, it is considered that the equipment is in maintenance period, a maintenance signal is issued, and the basic information of the equipment is called up and displayed next to the three-dimensional model.

[0059] Example 2, an embodiment of the present invention, provides a power plant panoramic data management method based on Internet of Things technology. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

The equipment archive information is obtained, the basic equipment information database is established, the equipment data is collected, and pre-processed. The Internet of Things technology is used to collect the operation data of the equipment in real time through sensors, including temperature, pressure, vibration, sound and image data. In order to maintain the fairness of the experimental company, the existing technology also uses the same processed data. The processed data is stored in the database for further analysis and visualization.

This is because the present invention ensures the accuracy and timeliness of the data through real-time data collection and preprocessing, which helps to better control the operating status of the equipment, plays a certain role in preprocessing, and significantly improves the service life of the equipment.

[0065] Furthermore, from the comparison data of image clarity, the present invention significantly improves the quality of image data.
