Description

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. They are close to live objects and there are certain safety hazards. Especially when the crane is performing high-altitude arm rotation, arm extension, cross operations and other links, there is no more accurate data to support, and it can only rely on naked eye observation. Due to weather, environment, distance, light and other conditions, inaccurate observation will occur. The crane can easily get too close to the live objects and cause safety accidents.

[0003] Based on the business scenario of substation, there is an application of electronic perimeter based on PDA, which realizes the positioning of perimeter and high-voltage line on PDA, realizes the real-time tracking of crane, and realizes the pre-alarm function on PDA. The real-time tracking and early warning function in this solution is to draw polygons on PDA, and use polygons as an electronic perimeter, that is, use a two-dimensional display method.

[0004] At present, the electronic perimeter displays a plane, on which the crane and the boom are displayed; and because the two-dimensional space only has the concepts of length and width, it lacks the dimensional display of the boom depth or boom height during the hoisting operation. The crane construction operation is mainly based on aerial hoisting operations, so it is difficult for this solution to observe the specific height and depth of the crane boom and the distance position of the actual electronic perimeter through the system on the PDA.

[0048] 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 1 The flowchart of an embodiment of a method for three-dimensional display of an electronic perimeter provided by the present invention is shown, and the method 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 the preset perimeter height value.

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

[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 a crane exists 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 2m by default, and can also be set according to actual conditions, and there is no limit here. For example, if the real-time height value of the crane is 3m, the first preset height value is 2m, and the preset perimeter height value is 5m.

[0055] When a high voltage line is arranged 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 2m by default and can be set according to actual conditions without limitation. For example, if the height value of the highest high-voltage line is 5m 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] By using 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, the target electronic perimeter corresponding to the perimeter of the target area is generated.

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

[0062] like Figure 2 As shown in the figure, for the XY coordinates of the screen on the PDA terminal, OpenGL ES technology will map the screen to the range of [-1,1], the left vertex of the screen corresponds to X = -1, and the right vertex of the screen corresponds to X = +1; the bottom edge of the screen corresponds to Y = -1, and the top edge of the screen corresponds to Y = +1. Regardless of the shape and size of the display screen of the PDA terminal, the range of coordinate values ​​is the same, and the electronic perimeter displayed on the screen needs to be drawn within this range.

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

[0064] In native development of the Android system, different layouts need to be loaded when switching between landscape and portrait screens. When running OpenGL ES technology, there are still adaptations to screen size, direction, etc. OpenGL ES uses projection to map the real world onto the screen. This mapping method makes it always look correct on different screen sizes or directions. The mapping is achieved through matrix transformation. The generated 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 virtualized 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 point in the upper right corner has a coordinate of [1,1] in the normalized coordinate space and a coordinate of [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 in the process of generating the target electronic perimeter: ① the vertex conversion of the preset perimeter height is stored in the 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 drawing can be customized; ④ due to the use of vertex arrays, it is necessary to know the position of the OpenGL vertex array on the Android plane.

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

[0070] When there is a crane in 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 wires and the crane boom can be mapped into the target electronic perimeter, so that the high-voltage wires and the crane boom present a more realistic form in space, and the target electronic perimeter can be rotated around any axis, thereby showing different perspectives and forms in the PDA terminal.

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

[0073] Among them, the warning height range is: [ha, h+a]; h is the height value of the high-voltage line (the highest high-voltage line), and a is the warning height threshold, which can be set according to the actual situation and is not limited here. For example, when h is 5m and a is 1m, the warning height range is [4m, 6m], that is, when the height of the crane boom is 4m-6m, the warning information is output. When no high-voltage line is set, there is no warning height range.

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

[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 perimeter of the target area and the preset perimeter height, which can realize the display of the three-dimensional electronic perimeter and meet the display needs of the aerial lifting operation.

[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 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 to display the target electronic perimeter in three dimensions through the PDA terminal.

[0080] In an optional manner, the acquisition module 210 is specifically used 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 arranged 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 for:

[0084] By using 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, the target electronic perimeter corresponding to the perimeter of the target area is generated.

[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 used to:

[0087] When there is a crane in 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;

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