Description

Technical Field

[0001] The present invention relates to the technical field of graphic signal display, and in particular to a signal strength visualization display method, system, electronic equipment and storage medium. Background Art

[0002] In recent years, the rapid development of drone technology has led to a gradual increase in communication demand in low-altitude areas (below 3,000 meters in altitude). However, due to historical reasons, the construction of communication facilities in low-altitude areas has not been fully considered, resulting in many signal blind spots in this area. At the same time, the electromagnetic environment in low-altitude areas is complex and easily affected by factors such as terrain, buildings and weather, and the signal propagation characteristics are complex. Especially in an environment with many and complex buildings, the diversity of building roofs has a significant impact on signal coverage. Therefore, graphical display of low-altitude signal coverage and visualization of the results have become an important means to improve communication coverage and optimize network layout.

[0003] Existing tools for processing and calculating electromagnetic signals (such as MATLAB, NS3, etc.) usually generate a large amount of complex data, the analysis and interpretation of which requires professional knowledge and experience. Traditional visualization displays are usually presented in the form of text or simple charts, which are difficult to understand intuitively, especially for non-professional technicians. This leads to inefficient information transmission and decision-making during system development, testing and optimization, increasing costs and time expenditures.

[0004] Compared with ground visualization, low-altitude visualization has higher requirements for visualization presentation. On the one hand, the range of visualization required in low-altitude areas is much larger than that of ground visualization. It is often necessary to visualize the signal strength of the airspace range between 50 and 300 meters. Therefore, the presentation of its visualization results is no longer the planar result of ground visualization, but a three-dimensional result. On the other hand, when a drone flies in the airspace, its speed is relatively fast, so the drone switches stations more frequently. The visualization results of a single station are difficult to present the overall signal changes during its flight process. Therefore, the joint drawing of multi-station visualization results and the drawing of drone trajectories are also an important content of low-altitude visualization. Therefore, in terms of visualization, the present invention mainly realizes the drawing of drone flight trajectories, the presentation of three-dimensional visualization results of a single station in the low-altitude area, the presentation of isosurfaces of visualization results of a single station in the low-altitude area, and the joint drawing of multiple stations in the low-altitude area.

[0005] In summary, among the existing technologies, the data generated by electromagnetic signal analysis and processing tools are relatively complex and difficult to interpret, and traditional visualization results are usually presented in the form of text or charts, which are difficult to understand intuitively, and the visualization results of a single station are difficult to present.

[0065] Embodiment 1

[0066] See also Figure 1 , which shows a signal strength visualization display method in a first embodiment of the present invention, the method comprises steps S1 to S4:

[0067] S1, obtaining low airspace signal coverage data, and preprocessing the signal coverage data to obtain preprocessed data;

[0068] Specifically, the step S1 includes steps S11 to S12:

[0069] S11, acquiring low-altitude signal coverage data based on a data acquisition tool, where the low-altitude signal coverage data includes signal strength, interference level, and channel state information;

[0070] S12, performing format conversion, denoising and normalization processing on the signal coverage data in sequence;

[0071] It can be understood that low-altitude signal coverage data is obtained from the data acquisition tool, and the signal coverage data includes signal strength, interference level and channel status information. The signal coverage data is then format converted, denoised and normalized to ensure the accuracy and consistency of the data.

[0072] S2, mapping the preprocessed data into a visualization format to generate a multidimensional data graph;

[0073] Specifically, the step S2 includes steps S21 to S22:

[0074] S21, grouping the preprocessed data, and performing data projection and graphics generation on the grouped preprocessed data;

[0075] S22, converting the preprocessed data into a visual format using a multidimensional data mapping method;

[0076] It can be understood that the preprocessed data is mapped into a format suitable for visualization to generate a multidimensional data graph. Specifically, the preprocessed data is first grouped, and then the grouped preprocessed data is projected, and the preprocessed data is converted into a format suitable for visualization using a multidimensional data mapping method.

[0077] S3, generating a plurality of interactive charts and interactive graphics based on the multidimensional data graphics;

[0078] It is understood that advanced visualization techniques are used to generate several interactive charts and several interactive graphics based on multidimensional data graphics;

[0079] In this embodiment, the visualization technology uses a 3D rendering engine to create a high-performance 3D scene to display the propagation path, attenuation and field strength distribution of wireless signals. Through fine light and shadow and material processing, the signal distribution in a complex environment can be more intuitively displayed.

[0080] Volume rendering technology, for three-dimensional field strength data, volume rendering technology can be used to visualize the spatial distribution of signal strength, especially suitable for displaying irregular signal attenuation and multipath effects. This technology can represent signals of different strengths by color or transparency.

[0081] Data heat map, combined with field strength data to generate a two-dimensional or three-dimensional heat map, using different colors to represent signal strength. Heat map technology makes signal coverage, blind spots and attenuation areas more intuitive. Heat maps can be superimposed on geographic space, floor maps, terrain, etc.

[0082] Contour map, generate a contour map of signal field strength to show different levels of signal strength. This technology can clearly show the signal attenuation area and coverage boundary.

[0083] In addition, in this embodiment, the signal strength visualization display method further includes steps S31 to S33:

[0084] S31, acquiring a plurality of measured points based on the flight trajectory of the drone, connecting the plurality of measured points in sequence to obtain a trajectory line, and generating a presentation area based on the trajectory line;

[0085] It can be understood that the flight trajectory of the UAV can be drawn by connecting the measured points in sequence to obtain the trajectory line, and the color of the trajectory line indicates the change of signal strength;

[0086] In this embodiment, the trajectory presentation of the measured points is to connect the measured points in sequence. Figure 2 as well as Figure 3 ,The black line in the figure is the trajectory of the measured point, and its color represents the signal strength of the point. Its specific value can be found from the color bar in the lower right corner of the figure;

[0087] After presenting the measured point trajectory, the changes in the measured signal strength in different areas can be easily seen from the color changes of the trajectory, which can provide a certain reference for improving the visualization accuracy. Figure 4 and Figure 5 The flight trajectory of a drone at an altitude of 100 meters in the scene. From the drawn trajectory, it can be seen that the corresponding signal value strength does not change too drastically, and is basically stable between -90dBm and -70dBm. Figure 2 Figure 3 The color change of the measured point trajectory in is very obvious, indicating that the intensity of the signal value has changed significantly on the entire measured trajectory.

[0088] S32, discretizing the presentation area into a plurality of measurement points, and layering the plurality of measurement points based on height to obtain a plurality of layered surfaces, and generating a plurality of stereoscopic visualization results based on the plurality of layered surfaces;

[0089] It can be understood that the three-dimensional display of the signal coverage of a single station discretizes the area to be presented into visualization points, which are layered in height, and each layer becomes a visualization surface to generate a three-dimensional visualization result;

[0090] It should be explained that the main scope of the stereoscopic visualization of a single station is the airspace area within 300 meters above the ground. The main way of presentation is to discretize the area to be presented into visualization points, layer them in height, and each layer becomes a visualization surface. After calculating all visualization surfaces, a stereoscopic result can be obtained. The stereoscopic visualization result is shown in Figure 6 , Figure 7 as well as Figure 8 ;

[0091] Figure 6 , Figure 7 as well as Figure 8 The result is obtained by uniformly sampling 10 layers of height, and the total number of visualization points is 1030410. Since the height is calculated in layers, the function of adjusting the section height is also provided during visualization, such as Fig. 9This is the initial visualization side view. The visualization height in this view is from 0 to 50 meters, with each layer being 5 meters. Fig.10 This is the visualization result of the top surface (50 meters high). By visualizing the cross section, you can view the visualization results of any layer, such as Fig.11 is the side view after adjusting the height of the cross section, and Fig.12 This is the top surface visualization result at this time.

[0092] In addition, in this embodiment, another way to present the stereoscopic visualization result is to present an isosurface. By adjusting the value of the current isosurface, the area corresponding to different values ​​can be obtained. Fig.13 as well as Fig.14 .

[0093] S33, superimposing a plurality of the three-dimensional visualization results to display the overall signal coverage;

[0094] It can be understood that the overlay display of signal coverage of multiple stations overlays the visualization results of multiple stations to show the overall signal coverage, so that blind spots and weak areas of signal coverage can be quickly identified;

[0095] It should be explained that, because an antenna generally only calculates the signal coverage of the 1600m×1600m range around it, and for airspace calculations, the same grid point is often affected by multiple antennas. When visualizing calculations, it is necessary to consider the problem of superposition of visualization results of multiple different antennas. Therefore, when visualizing, it is more important to draw multiple sites together. Here we take a scene as an example to explain;

[0096] Fig.15 This is the visualization result of the 4000m×4000m grid of 25 antennas in use, and then the result of superimposing these visualization surface results by taking the higher value on the same grid. This figure basically shows the overall signal coverage of the block in this scenario. It can be seen that the signal strength is quite strong on the streets covered by the antennas, while the signal is relatively weak in the residential areas far away from the antennas;

[0097] Fig.16 This is the grid coverage result obtained after visual calculation of 25 antennas in the scene at low altitude (100 meters). Fig.15 As for the ground visualization results, at an altitude of 100 meters, the signal value of the block area generally changes smoothly and basically remains in a strong range;

[0098] Fig.17 This is the signal coverage result at an altitude of 200 meters. Fig.16,At an altitude of 200 meters, the overall signal energy value is relatively weak, but generally still maintains around -90dBm to -70dBm;

[0099] Fig.18 This is the visualization result at an altitude of 300 meters. From the visualization result, it can be seen that at an altitude of 300 meters, the signal strength further decreases. Compared with the altitude of 200 meters, the signal fluctuation at an altitude of 300 meters is more obvious.

[0100] S4, obtaining data points in the interactive chart and the interactive graph, and obtaining data information of the data points, and adjusting the interactive chart and the interactive graph based on actual needs;

[0101] Specifically, the step S4 includes step S41:

[0102] S41, dynamically adjusting the viewing angle, dynamically scaling the graphics, and filtering data for the interactive chart and the interactive graphics according to actual needs of the user;

[0103] It is understandable that a variety of interactive functions can be provided, and users can dynamically adjust the viewing angle, zoom the graph, filter data, and dynamically update according to actual needs. They can also view detailed data information by clicking on data points in the graph.

[0104] In this embodiment, for profile analysis, users can select a plane for sectioning, view the signal distribution on the plane, and conduct detailed analysis from different heights or specific sections; for heat map display, the signal strength distribution can be intuitively displayed in the form of a color heat map, and users can set different threshold ranges or adjust color mapping through interactive heat maps to highlight different signal strength areas; for signal path and strength detection, users can set specific points or paths to track the signal strength or propagation path of a specific small area, helping to understand the propagation characteristics of the signal in buildings or obstacles. Finally, export is supported, and users can export charts as static images, PDFs, or editable formats (such as Excel, CSV).

[0105] In summary, the signal strength visualization display method in the above-mentioned embodiment of the present invention maps the preprocessed data into a visualization format so that the multidimensional data graphics can intuitively represent the visualization content, and through the interactive charts and interactive graphics generated by the multidimensional data graphics, the visualization results can be intuitively presented, and by adjusting the interactive charts and interactive graphics, the visualization results can be presented more intuitively according to user needs.
