Description

Technical Field

[0001] The present invention relates to the technical field of electronic perimeters, and in particular to a three-dimensional display method, system, electronic device and storage medium for an electronic perimeter. Background Art

[0002] The construction, expansion, technical transformation, overhaul and other in-station construction lifting and transportation of substations cannot be separated from the cooperation of lifting cranes, and they are close to live objects, which poses certain safety hazards. In particular, when the crane is performing high-altitude arm rotation, arm extension, cross operations and other links, there is no more accurate data to support it, and it can only rely on naked eye observation. Due to weather, environment, distance, light and other conditions, inaccurate observations may occur. The crane can easily get too close to the live objects, causing safety accidents.

[0003] Based on the substation business scenario, a PDA-based electronic perimeter application is available. This allows perimeter and high-voltage line positioning, real-time tracking of crane booms, and early warning functions on the PDA. This real-time tracking and early warning feature involves drawing a polygon on the PDA as an electronic perimeter, using a two-dimensional display.

[0004] Currently, the electronic perimeter displays a flat surface, displaying both the crane and boom. Because two-dimensional space only has the concepts of length and width, it lacks the dimensionality of the boom's depth or height during lifting operations. Since crane construction operations primarily involve aerial lifting, this solution makes it difficult to visualize the specific height and depth of the crane boom and its actual position relative to the electronic perimeter using the PDA system.

[0005] Therefore, it is urgent to provide a technical solution to solve the above problems. Summary of the Invention

[0006] To solve the above technical problems, the present invention provides a method, system, electronic device and storage medium for three-dimensional display of an electronic perimeter.

[0015] When a high-voltage line is arranged in the perimeter of the target area, the sum of the maximum high-voltage line height value and a second preset height value is determined as the preset perimeter height value.

[0016] In the above alternative way, the preset perimeter height value under different situations is further defined, and the dynamic setting of the perimeter height value is realized.

[0017] In an alternative way, according to the position information of each plane vertex, the preset perimeter height value and the display specification parameters of the PDA terminal, the step of generating the target electronic perimeter corresponding to the perimeter of the target area comprises:

[0019] In an alternative way, the display specification parameters comprise a display size and a display direction.

[0020] In an alternative way, the method further comprises:

[0021] When the crane exists in the perimeter of the target area, according to the current position information of the crane, the crane is mapped into the target electronic perimeter in real time to generate a crane model corresponding to the crane;

[0022] When the jib of the crane model is in a pre-warning height range or a pre-warning edge range, a pre-warning information is output.

[0023] In the above alternative way, the real-time pre-warning and monitoring of the three-dimensional electronic perimeter are further realized.

[0024] In a second aspect, the present invention provides an electronic perimeter three-dimensional display system, the technical solution of which is as follows:

[0025] Includes: acquisition module and display module;

[0026] The acquisition module is used to: determine the position information of each plane vertex of the perimeter of the target area and the preset perimeter height value;

[0048] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0049] Figure 1The figure shows a flow chart of an embodiment of a method for displaying a three-dimensional electronic perimeter provided by the present invention, which is applied to a PDA terminal. Figure 1 As shown, the following steps are included:

[0050] S1. Determine the position information of each plane vertex of the perimeter of the target area and a preset perimeter height value.

[0051] The target area perimeter refers to the outer boundary or limit surrounding a specific target or area. The target area perimeter can be a two-dimensional space with length and width (plane space) or a three-dimensional space with length, width, and height (stereoscopic space). The plane space of the target area perimeter has multiple plane vertices. The location information of the plane vertices includes: the geographic coordinates (latitude and longitude information) of the vertices. The preset perimeter height value is the preset maximum height value of the target area perimeter.

[0052] In S1, the step of determining the preset perimeter height value includes:

[0053] When no high-voltage line is set within the perimeter of the target area and when there is a crane within the perimeter of the target area, the sum of the real-time height value of the crane and the first preset height value is determined as the preset perimeter height value.

[0054] The first preset height value is set to 2m by default and can be set according to actual conditions. There is no limit here. For example, if the real-time height value of the crane is 3m and the first preset height value is 2m, then the preset perimeter height value is 5m.

[0055] When a high-voltage line is set within the perimeter of the target area, the sum of the maximum high-voltage line height value and the second preset height value is determined as the preset perimeter height value.

[0056] The second preset height value is set to 2m by default and can be set according to actual conditions. There is no limit here. For example, if the highest high-voltage line is 5m high and the second preset height value is 2m, then the preset perimeter height value is 7m.

[0057] S2. Generate a target electronic perimeter corresponding to the perimeter of the target area according to the position information of each plane vertex, the preset perimeter height value, and the display specification parameters of the PDA terminal, and display the target electronic perimeter in three dimensions through the PDA terminal.

[0058] The display specification parameters include but are not limited to: display size and display direction.

[0059] In S2, specifically:

[0060] The target electronic perimeter corresponding to the perimeter of the target area is generated by utilizing OpenGL ES technology and combining the position information of each plane vertex, the preset perimeter height value, and the display specification parameters of the PDA terminal.

[0061] The electronic perimeter (system or program) in the PDA terminal is natively developed using the Android system. Considering the current memory and CPU limitations of Android terminal devices, OpenGL ES technology is used in this embodiment to implement a pseudo-3D application of the electronic perimeter. OpenGL ES technology is a cross-platform 3D graphics API interface suitable for low-power devices. It can be used to render efficient 3D graphics on embedded devices and mobile devices (including mobile phones, large-screen vehicles, PDA terminals, and other embedded electrical terminal devices). The smallest unit of a 3D image is called a point or vertex, which represents a point in three-dimensional space and is used to construct more complex objects. A polygon is composed of a series of points, while an object is composed of multiple polygons. Although OpenGL generally supports polygons, OpenGL ES only supports triangles. Therefore, when drawing a square, it needs to be split into two triangles for drawing.

[0062] like Figure 2 As shown in the figure, OpenGL ES maps the X and Y coordinates of a PDA screen to the range [-1, 1]. The left vertex of the screen corresponds to X = -1, while the right vertex corresponds to X = +1. The bottom edge of the screen corresponds to Y = -1, while the top edge corresponds to Y = +1. Regardless of the shape and size of the PDA screen, the coordinate range remains the same, and electronic boundaries must be drawn within this range.

[0063] It should be noted that the screen adaptation algorithm of OpenGL ES technology is:

[0064] In native Android development, different layouts need to be loaded when switching between landscape and portrait orientations. When running OpenGL ES technology, adaptation to screen size and orientation is still required. OpenGL ES uses projection to map the real world onto the screen. This mapping method ensures that it always looks correct regardless of screen size or orientation. Mapping is achieved through matrix transformation. The resulting orthogonal projection matrix is:

[0065]

[0066] The virtual coordinate space and the normalized coordinate space are converted through the orthogonal projection matrix. Taking the horizontal screen mode with a resolution of 1920*1080 as an example, the X-axis range of the virtual coordinate space is [-1920 / 1080, 1920 / 1080], that is, [-1.78, 1.78]. The screen itself is the normalized coordinate space [-1, 1]. For example, the coordinates of the point in the upper right corner are [1, 1] in the normalized coordinate space, and [1.78, 1] in the virtualized coordinate space. After the above orthogonal projection matrix conversion, the conversion returns to a matrix. The normalized matrix is:

[0067]

[0068] It should be noted that during the generation of the target electronic perimeter: ① The vertex conversion of the preset perimeter height is stored in a byte buffer; ② All the vertices of the perimeter are formed into an array, and the vertex array is used to draw the graphics; ③ The color of the target electronic perimeter can be customized; ④ Since a vertex array is used, the position of the OpenGL vertex array on the Android plane must be known.

[0069] In an optional manner, the method further includes:

[0070] When there is a crane within the perimeter of the target area, the crane is mapped to the target electronic perimeter in real time according to the current position information of the crane, and a crane model corresponding to the crane is generated.

[0071] Among them, after the target electronic perimeter has depth or height, the high-voltage line and the crane arm can be mapped into the target electronic perimeter, so that the high-voltage line and the crane arm present a more realistic shape in space, and the target electronic perimeter can be rotated around any axis, thereby showing different perspectives and shapes in the PDA terminal.

[0072] When the boom of the crane model is in a warning height range or a warning edge range, a warning message is output.

[0073] The warning height range is [ha, h+a], where h is the height of the high-voltage line (the highest high-voltage line), and a is the warning height threshold. This value can be set based on actual conditions and is not limited here. For example, if h is 5m and a is 1m, the warning height range is [4m, 6m]. This means that a warning message will be issued when the crane boom height is between 4m and 6m. If no high-voltage line is present, there is no warning height range.

[0074] The warning edge range is defined as the distance between the crane model and the boundary of the target electronic perimeter being less than a preset value, such as 1 meter. For example, a warning message is output when the distance between the crane model and any boundary position of the target electronic perimeter is less than 1 meter.

[0075] It should be noted that the output of the warning information can be voice prompts, text prompts or display prompts (such as Figure 3 and Figure 4 As shown, the crane model within the target electronic perimeter is marked and displayed).

[0076] The technical solution of this embodiment generates an electronic perimeter that meets the display requirements of the PDA terminal through the plane vertices of the target area perimeter and the preset perimeter height, which can realize the display of the three-dimensional electronic perimeter and meet the display needs of aerial lifting operations.

[0078] The acquisition module 210 is used to: determine the position information of each plane vertex of the perimeter of the target area and the preset perimeter height value;

[0079] The display module 220 is used to generate a target electronic perimeter corresponding to the target area perimeter based on the position information of each plane vertex, the preset perimeter height value and the display specification parameters of the PDA terminal, and to perform a three-dimensional display of the target electronic perimeter through the PDA terminal.

[0080] In an optional manner, the acquisition module 210 is specifically configured to:

[0081] When there is no high-voltage line within the perimeter of the target area and when there is a crane within the perimeter of the target area, the sum of the real-time height value of the crane and the first preset height value is determined as the preset perimeter height value;

[0082] When a high-voltage line is set within the perimeter of the target area, the sum of the maximum high-voltage line height value and the second preset height value is determined as the preset perimeter height value.

[0083] In an optional manner, the display module 220 is specifically used to:

[0084] The target electronic perimeter corresponding to the perimeter of the target area is generated by utilizing OpenGL ES technology and combining the position information of each plane vertex, the preset perimeter height value, and the display specification parameters of the PDA terminal.

[0085] In an optional manner, the display specification parameters include: display size and display direction.

[0086] In an optional manner, the system further includes an early warning module; the early warning module is configured to:

[0087] When there is a crane within the perimeter of the target area, mapping the crane to the target electronic perimeter in real time based on the current position information of the crane, and generating a crane model corresponding to the crane;

[0088] When the boom of the crane model is in a warning height range or a warning edge range, a warning message is output.
