Description

Technical Field

[0001] This invention relates to the field of ultra-dense wireless network technology, and more specifically to a method, apparatus, electronic device, and medium for drawing wireless signal heatmaps. Background Technology

[0002] With the continuous development of wireless network technology, multi-story buildings such as shopping malls, hospitals, and office buildings are densely equipped with AP (Access Point) devices, forming ultra-dense wireless networks to support a large number of users within the building to move freely and maintain wireless connectivity. To rationally plan the signal coverage of AP devices within multi-story buildings and maintain and optimize network performance and user experience, it is necessary to create wireless signal heatmaps for these buildings. A Wi-Fi heatmap is a tool that uses visualization technology to display the distribution of wireless signal strength, coverage, and quality. It is typically presented in the form of color gradients (such as red, yellow, and green) or contour lines to provide an intuitive understanding of signal strength in different areas.

[0003] In existing technologies, wireless signal heat maps are typically created using on-site measurements or floor modeling. On-site measurements require personnel to obtain signal strength data at different locations and then create the heat map. However, applying this method to multi-story buildings is extremely resource-intensive and time-consuming.

[0004] The traditional floor modeling method directly calculates signal strength by obtaining the number of floors that the wireless access point penetrates between the wireless access point and the measurement point from the building data, and then draws a wireless signal heat map. However, for buildings such as shopping malls or hospitals with open areas such as atriums inside the building, the number of floors that the wireless access point on the i-th floor penetrates between the measurement point on the j-th floor is not fixed. It is impossible to directly obtain the number of floors that the wireless access point penetrates from the building data, which makes the signal strength calculation inaccurate, and thus the accuracy of the drawn wireless signal heat map is not high.

[0023] Combination Figure 1 As shown, this disclosure provides a method for drawing a wireless signal heatmap, the method comprising: Step S101: Obtain the number of floors traversed and the number of open areas between the wireless access point and the signal point to be detected in the preset multi-story building.

[0024] Step S102: Obtain the signal strength of the wireless access point at the signal point to be detected based on the number of layers traversed and the number of hollowed-out areas.

[0025] Step S103: Draw a wireless signal heat map corresponding to a multi-story building based on the signal strength.

[0026] The method for drawing wireless signal heatmaps provided in this disclosure involves obtaining the number of layers a wireless access point traverses and the number of open areas between it and a signal point to be detected in a pre-defined multi-story building. Then, the signal strength of the wireless access point at the signal point to be detected is obtained based on these dimensions. Finally, a wireless signal heatmap corresponding to the multi-story building is drawn based on the signal strength. Compared to existing technologies that use on-site measurements or floor modeling to draw wireless signal heatmaps, this application achieves accurate signal strength calculation without requiring on-site measurement. This allows for precise drawing of the wireless signal heatmap corresponding to the multi-story building based on the accurate signal strength, thus realizing automatic drawing of the wireless signal heatmap for multi-story buildings and improving the accuracy of the wireless signal heatmap while saving manpower and resources.

[0027] It should be noted that the preset multi-story building refers to a building with multiple floors. Multi-story buildings can be residential buildings, office buildings, shopping mall buildings, hospital buildings, or hotels, etc.

[0028] In a multi-story building, there are multiple signal points to be detected. In some embodiments, each floor of the multi-story building is divided into a grid, such that the signal point to be detected is the center point of each grid.

[0029] Multi-story buildings typically contain multiple wireless access points (APs). A wireless access point is an access point for users of mobile devices such as smartphones and wireless devices such as laptops to access a wired network. Wireless access points include access point devices such as wireless access nodes, session points, access bridges, and wireless routers.

[0030] The signal strength of the same wireless access point varies depending on its location. Even when the signal point is in the same location, different wireless access points will have different signal strengths at that same location. Therefore, it is necessary to calculate the signal strength of different wireless access points under different signal conditions to create a wireless signal heatmap.

[0031] Furthermore, in a pre-defined multi-story building, the number of floors traversed and the number of open areas between the wireless access point and the signal point to be detected are obtained, including: obtaining the first floor number of the first floor where the signal point to be detected is located; obtaining the second floor number of the second floor where the wireless access point is located; obtaining the first coordinates corresponding to the signal point to be detected based on the first floor number; the first coordinates include the position of the signal point to be detected within the first floor and the first floor number; obtaining the second coordinates corresponding to the wireless access point based on the second floor number; the second coordinates include the position of the wireless access point within the second floor and the second floor number; obtaining the number of floors traversed and the number of open areas between the wireless access point and the signal point to be detected based on the first and second coordinates.

[0032] In this way, by using the first coordinates, which include the location and number of the first floor of the signal to be detected, and the second coordinates, which include the location and number of the second floor of the wireless access point, the number of floors traversed and the number of cutout areas between the wireless access point and the signal to be detected can be accurately obtained. This allows the signal strength of the wireless access point at the signal to be detected to be obtained based on the number of floors traversed and the number of cutout areas. As a result, accurate calculation of signal strength can be achieved without the need for on-site measurement of signal strength by manpower and resources.

[0033] Meanwhile, by using a four-dimensional coordinate system of location and floor number to characterize the location of wireless access points and the location of signal points to be detected in multi-story buildings, the accuracy of signal strength calculation is improved by enabling the calculation and superposition of signal strength across floors in multi-story buildings.

[0034] It should be noted that the floor of the first floor where the signal point to be detected is located is used as the xy-plane of the three-dimensional coordinate system to obtain the first coordinate of the signal point. The floor of the second floor where the wireless access point is located is used as the xy-plane of the three-dimensional coordinate system to obtain the second coordinate of the wireless access point. The x, y, and z axes of the three-dimensional coordinate system are the same for all floors. The origin is in the same relative position on each floor; for example, the origin can be the lower left corner, lower right corner, upper left corner, upper right corner, or center point of the floor.

[0035] Furthermore, the first floor where the signal point to be detected is located is the... Layer, the signal point to be detected is in the layer. The location within the layer is Then the first floor number of the first floor where the signal point to be detected is located is The first coordinate corresponding to the signal point to be detected is .in, Characterizes the floor where the signal point to be detected is located; It represents the height of the signal point to be detected within the floor it is located on; They collectively characterize the planar position of the signal point to be detected.

[0036] In some embodiments, since the signal points to be detected are arranged in a grid pattern on each floor of a multi-story building, the center point of each grid is the signal point to be detected. For example... Figure 2 As shown, Figure 2 For the first A schematic diagram of the layer's mesh. Combined with... Figure 2 As shown, in When, define the first The layer has M grids in the X direction and N grids in the y direction, and the grids are square grids. The side length of each grid is g. The coordinates of the center point of the signal point A to be detected are the center point of the m-th grid in the x direction and the n-th grid in the y direction. The x-coordinate of the signal point A to be detected is m×g - 0.5×g; the y-coordinate of the signal point A to be detected is n×g - 0.5×g. That is, the x-coordinate of the signal point A to be detected is m×g - 0.5×g. The value is m×g-0.5×g; the signal A at the point to be detected is... The value is n×g-0.5×g; since electronic devices such as laptops and mobile phones that require wireless network access are usually placed on a desktop to connect to a wireless network, the height H of the table from the ground can be taken as the height of the signal point to be detected within the floor. Therefore, the height of the signal point A to be detected... Let H be the coordinates of the signal point A to be detected. .

[0037] Furthermore, the second floor where the wireless access point is located is the... Layer, wireless access point is on the The location within the layer is Then the second floor number of the second floor where the wireless access point is located is The second coordinate corresponding to the wireless access point is .in, The floor where the wireless access point is located; This indicates the height of the wireless access point within the floor it is located on; They collectively represent the planar location of the wireless access point.

[0038] It's important to note that x, y, z, and f have no actual meaning. The first and second coordinates are formed by adding a fourth coordinate axis, f, to the existing x, y, and z axes of a Cartesian three-dimensional coordinate system. The f axis represents the floor where the signal point or wireless access point is located. Thus, compared to three-dimensional coordinates, the floor and its location within a floor can be intuitively displayed in four-dimensional coordinates.

[0039] Furthermore, the number of layers traversed and the number of hollowed-out areas between the wireless access point and the signal point to be detected are obtained based on the first coordinate and the second coordinate, including: obtaining the number of layers traversed based on the first number of layers and the second number of layers; determining the intersection points of the signal propagation line between the wireless access point and the signal point to be detected with the planes corresponding to the floors of each floor in a multi-story building based on the first coordinate and the second coordinate; determining whether each intersection point is within a preset hollowed-out area; and accumulating the number of intersection points within the preset hollowed-out area to obtain the number of hollowed-out areas.

[0040] In this way, by obtaining the number of traversed layers based on the first and second layer counts, and determining the intersection points of the signal propagation line between the wireless access point and the target signal point with the corresponding planes of each floor in a multi-story building based on the first and second coordinates, the number of intersection points within a preset hollow area is accumulated to obtain the number of hollow areas. Even if the construction data of the multi-story building is lost or incorrect, the number of traversed layers and the number of hollow areas between the wireless access point and the target signal point can be accurately obtained, reducing misjudgments of the building structure and achieving accurate calculation of the number of traversed layers and hollow areas. This allows for precise acquisition of the signal strength of the wireless access point at the target signal point based on the number of traversed layers and hollow areas, enabling accurate calculation of signal strength without the need for on-site measurement by manpower and resources.

[0041] Furthermore, the number of traversed layers is obtained based on the first and second layer numbers, including: through calculation. This gives you the number of floors traversed. This refers to the number of floors traversed. The second floor number of the second floor where the i-th wireless access point is located; The first floor number of the first floor where the signal point to be detected is located.

[0042] It should be noted that since the wireless access point may traverse 0, 1, or more floors to the signal point to be detected, there may be multiple intersections between the signal propagation line between the wireless access point and the planes corresponding to the floors of each floor in a multi-story building. Each intersection needs to be confirmed to be within the pre-defined cutout area.

[0043] Furthermore, it is determined whether each intersection point is within the preset cutout area, including: obtaining the coordinate range of the cutout area; and determining whether the coordinates of each intersection point are within the coordinate range of the cutout area.

[0044] It should be noted that the preset cutout area is the cutout area of ​​the floor of the floor where each intersection point is located. This cutout area can be obtained based on the building data of a multi-story building, or it can be obtained through manual measurement or 3D scanning; there are no restrictions here.

[0045] In some embodiments, if a multi-story building has an atrium or courtyard that extends from the 1st to the 5th floor, then the floors of the 1st, 2nd, 3rd, 4th and 5th floors all have openwork areas.

[0046] It should be noted that the total number of intersections within the preset hollow area is used to obtain the number of hollow areas. In other words, the total number of intersections within the preset hollow area is the number of hollow areas.

[0047] Furthermore, determining the intersection of the signal propagation line between the wireless access point and the target signal point with the plane corresponding to the floor of each floor in the multi-story building based on the first and second coordinates includes: obtaining the floor height of each floor in the multi-story building; converting the first coordinate to a third coordinate; the third coordinate is used to characterize the position of the target signal in the multi-story building; converting the second coordinate to a fourth coordinate; the fourth coordinate is used to characterize the position of the wireless access point in the multi-story building; obtaining the straight line formula corresponding to the signal propagation line based on the third and fourth coordinates; and determining the intersection point based on the floor height and the straight line formula.

[0048] In this way, by first obtaining the floor height of each floor, then converting the first coordinate into a third coordinate representing the position of the signal to be detected in a multi-story building, and converting the second coordinate into a fourth coordinate representing the position of the wireless access point in a multi-story building, the straight line formula corresponding to the signal propagation line is obtained based on the third and fourth coordinates, and then the intersection point is determined based on the floor height and the straight line formula, the precise positioning of the intersection point is achieved. This allows for accurate acquisition of the signal strength of the wireless access point at the signal point to be detected based on the number of floors traversed and the number of open areas, thus enabling accurate calculation of signal strength without the need for on-site measurement of signal strength by manpower and resources.

[0049] Furthermore, converting the first coordinate to the third coordinate includes: using the x-axis value of the first coordinate as the x-axis value of the third coordinate; using the y-axis value of the first coordinate as the y-axis value of the third coordinate; and obtaining the z-axis value of the third coordinate based on the z-axis value and f-axis value of the first coordinate.

[0050] Furthermore, obtaining the z-axis value of the third coordinate based on the z-axis and f-axis values ​​of the first coordinate includes: calculating... This yields the z-axis value of the third coordinate. The z-axis value of the third coordinate; Let k be the floor height of the kth floor; It represents the height of the signal point to be detected within the floor it is located on; The first layer number of the signal point to be detected.

[0051] Furthermore, converting the second coordinate into the fourth coordinate includes: using the x-axis value of the second coordinate as the x-axis value of the fourth coordinate; using the y-axis value of the second coordinate as the y-axis value of the fourth coordinate; and obtaining the z-axis value of the fourth coordinate based on the z-axis value and f-axis value of the second coordinate.

[0052] Furthermore, obtaining the z-axis value of the fourth coordinate based on the z-axis and f-axis values ​​of the second coordinate includes: calculating... This yields the z-axis value of the fourth coordinate. The z-axis value of the third coordinate; Let k be the floor height of the kth floor; This indicates the height of the wireless access point within the floor it is located on; This refers to the first layer number where the wireless access point is located.

[0053] In some embodiments, the floor height of each floor ,in, The total number of floors in the building; This refers to the floor height of the first floor. This refers to the floor height of the second floor. The floor height of the k1th floor; The floor height is the k2th floor. For the first The floor height of the floor.

[0054] The first coordinates corresponding to the signal point to be detected are (A, B, C, k1). These first coordinates represent the position of the signal on its corresponding floor. Converting these first coordinates to third coordinates gives the third coordinates as follows: ,Right now The third coordinate is the spatial position of the signal point to be detected relative to the first floor, that is, the position of the signal point to be detected in a multi-story building.

[0055] The second coordinates corresponding to the wireless access point are (D, E, G, k2). These second coordinates represent the location of the wireless access point on its floor. Converting these second coordinates to fourth coordinates gives us the fourth coordinates as follows: ,Right now The fourth coordinate represents the spatial location of the wireless access point relative to the first floor, i.e., the location of the wireless access point within a multi-story building.

[0056] Furthermore, based on the third and fourth coordinates, the formula for the straight line corresponding to the signal propagation line is obtained, including: The formula for the straight line corresponding to the signal propagation line is determined. Here, x, y, and z are variables; x is the x-axis value of any point in the formula for the straight line corresponding to the signal propagation line; y is the y-axis value of any point in the formula for the straight line corresponding to the signal propagation line; and z is the z-axis value of any point in the formula for the straight line corresponding to the signal propagation line. The x-axis value of the fourth coordinate corresponding to the wireless access point; This is the y-axis value of the fourth coordinate corresponding to the wireless access point; This is the z-axis value of the fourth coordinate corresponding to the wireless access point; The fourth coordinate corresponding to the wireless access point; The x-axis value of the third coordinate corresponding to the signal point to be detected; The y-axis value is the third coordinate corresponding to the signal point to be detected; The z-axis value of the third coordinate corresponding to the signal point to be detected; The third coordinate is the coordinate of the signal point to be detected.

[0057] Furthermore, the intersection point is determined based on the floor height and the straight line formula, including: obtaining the floor height of each floor from the floor of the preset floor number based on the floor height of each floor; substituting each floor height into the straight line formula corresponding to the signal propagation line to obtain the intersection point of the signal propagation line and the plane corresponding to each floor.

[0058] Furthermore, based on the floor height of each floor, the floor height of each floor relative to the preset floor number is obtained, including: through calculation. , to obtain the floor height of the b-th floor. The floor height of the b-th floor; is the floor height of the kth floor; b is the preset floor number.

[0059] It should be noted that the preset number of layers includes the floor levels corresponding to the intervals between the wireless access point and the signal point to be detected. For example, if the wireless access point is on the 3rd floor and the signal point to be detected is on the 5th floor, then the floor levels between the wireless access point and the signal point to be detected are the floors of the 4th and 5th floors. Therefore, the preset number of layers is 4 and 5.

[0060] In some embodiments, the floor height of each floor can be obtained in advance based on the floor height of each floor, and then the floor height of the preset number of floors is substituted into the straight line formula corresponding to the signal propagation line to obtain the intersection point of the signal propagation line and the plane corresponding to each floor.

[0061] Furthermore, by substituting the heights of each floor into the formula for the straight line corresponding to the signal propagation line, the intersection points of the signal propagation line and the planes corresponding to each floor are obtained, including: Substituting the z-axis value of any point in the formula for the straight line corresponding to the signal propagation line into the formula... In the middle, obtain Corresponding x-axis values ​​and The corresponding y-axis value; based on , Corresponding x-axis values ​​and The corresponding y-axis value determines the intersection point of the signal propagation line with the plane corresponding to each floor.

[0062] It should be noted that the coordinates ( The corresponding x-axis value, The corresponding y-axis value, ( ) represents the coordinates of a point in the signal propagation line, which is the intersection of the signal propagation line with the plane corresponding to each floor.

[0063] Furthermore, the signal strength of the wireless access point at the signal point to be detected is obtained based on the number of layers traversed and the number of perforated areas, including: determining the number of floors the signal propagation lines between the wireless access point and the signal point to be detected cross based on the number of layers traversed and the number of perforated areas; obtaining the spatial distance between the wireless access point and the signal point to be detected; and obtaining the signal strength based on the spatial distance and the number of floors traversed.

[0064] In this way, by determining the number of floors the signal propagation line traverses between the wireless access point and the signal point to be tested based on the number of floors traversed and the number of open areas, and then obtaining the signal strength of the wireless access point at the signal point to be tested based on the obtained spatial distance between the wireless access point and the signal point to be tested and the number of floors traversed, the accurate calculation of signal strength is achieved. Thus, the accurate calculation of signal strength can be achieved without the need for on-site measurement of signal strength by manpower and resources.

[0065] It should be noted that in multi-story buildings such as shopping malls, hospitals, or hotels with open spaces, the wireless access point may or may not pass through these open spaces. This means that the number of floors the signal propagation line passes through from the wireless access point to the signal point is less than or equal to the number of floors it passes through. Therefore, it is necessary to obtain the number of floors and open spaces between the wireless access point and the signal point to accurately determine the number of floors to pass through, thereby enabling accurate calculation of signal strength.

[0066] Furthermore, the number of floor crossings for the signal propagation line between the wireless access point and the signal point to be detected is determined based on the number of traversed layers and the number of perforated areas, including: determining the difference between the number of traversed layers and the number of perforated areas as the number of floor crossings for the signal propagation line between the wireless access point and the signal point to be detected.

[0067] Furthermore, obtaining the spatial distance between the wireless access point and the signal point to be detected includes: obtaining the first floor number of the first floor where the signal point to be detected is located; obtaining the second floor number of the second floor where the wireless access point is located; obtaining the relationship between the first floor number and the second floor number; and obtaining the spatial distance based on the relationship.

[0068] In this way, the spatial distance is obtained by considering the relationship between the first floor number of the first floor where the signal point to be detected is located and the second floor number of the second floor where the wireless access point is located. This enables accurate calculation of the spatial distance, allowing for precise determination of the signal strength of the wireless access point at the signal point to be detected based on the number of floors traversed and the number of open areas. This allows for accurate calculation of signal strength without requiring on-site measurement by manpower and resources.

[0069] Furthermore, spatial distance is obtained based on size relationships, including: when the second floor number of the second floor where the wireless access point is located is less than or equal to the first floor number of the first floor where the signal point to be detected is located, by calculation. , obtain the spatial distance between the i-th wireless access point and the signal point to be detected. And / or, if the second floor number of the second floor where the wireless access point is located is greater than the first floor number of the first floor where the signal point to be detected is located, calculate , obtain the spatial distance between the i-th wireless access point and the signal point to be detected. Wherein, H represents the spatial distance between the i-th wireless access point and the signal point to be detected; H represents the height of the signal point to be detected within its floor.

[0070] Furthermore, signal strength is obtained based on spatial distance and the number of floors traversed, including: obtaining the signal power and frequency band corresponding to the wireless access point; and, when the spatial distance is less than or equal to a preset distance, calculating... Obtain the signal strength of the i-th wireless access point at the signal point to be detected. And / or, if the spatial distance is greater than a preset distance, calculate... , obtain the signal strength of the i-th wireless access point at the signal point to be detected. Where, Let be the signal strength of the i-th wireless access point at the signal point to be detected; Let be the signal power corresponding to the i-th wireless access point; The number of floors crossed by the signal propagation line between the i-th wireless access point and the signal point to be detected; Let be the spatial distance between the i-th wireless access point and the signal point to be detected; This refers to the signal frequency band corresponding to the i-th wireless access point; in some embodiments, The signal strength is 2.4G or 5.2G; in some embodiments, the preset distance is 10 meters. The propagation mode of the signal strength within 10 meters is different from that beyond 10 meters, therefore, the calculation method is also different.

[0071] It should be noted that in the formula In the equation, 40.05 is the preset attenuation constant; 18.3 is the preset floor attenuation coefficient.

For crossing Signal attenuation after the floor layer; Within a preset distance, the distance Signal attenuation at long distances; The signal frequency band is The amount of signal attenuation under certain conditions.

[0073] Through various attenuation coefficients and the number of floors crossed By dynamically correcting the signal strength, accurate calculation of the signal strength is achieved.

[0074] Furthermore, a wireless signal heatmap is drawn based on the signal strength of the multi-story building, including: for each signal point to be detected, obtaining the maximum signal strength among the signal strengths corresponding to the signal point to be detected; determining the signal strength distribution of the multi-story building based on the maximum signal strength corresponding to each signal point to be detected; and drawing a wireless signal heatmap based on the signal strength distribution of the multi-story building.

[0075] This method involves acquiring the maximum signal strength for each signal point to be detected, then determining the signal strength distribution across multiple floors of the building based on the maximum signal strength at each point, and finally creating a wireless signal heatmap based on this distribution. This achieves precise visualization of signal strength distribution, thereby improving the accuracy of wireless signal heatmaps for multi-story buildings while saving manpower and resources. Furthermore, the visualization of signal strength across multiple floors allows staff to directly maintain and optimize the high-density wireless network within the building, providing reliable technical support for high-density wireless network deployment. It should be noted that for each signal point to be detected, the signal strength of each wireless access point at that point needs to be calculated. Then, among the signal strengths of all wireless access points at that point, the maximum signal strength is obtained.

[0076] In some embodiments, for signal point A to be detected, the signal strength of each wireless access point at that signal point is: ;in, The signal strength of the first wireless access point at the signal point A to be detected; The signal strength of the second wireless access point at the signal point A to be tested; Let be the signal strength of the i-th wireless access point at the signal point A to be detected; Let be the signal strength of the i-th wireless access point at the signal point A to be detected. Then, the maximum signal strength corresponding to the signal point A to be detected is... .

[0077] In some embodiments, the signal strength distribution of a multi-story building is determined based on the maximum signal strength corresponding to each signal point to be detected. That is, for each signal point to be detected on each floor, the signal strength distribution of each floor is obtained based on the location of each signal point to be detected and the maximum signal strength corresponding to each signal point to be detected; the signal strength distribution of the multi-story building is obtained based on the signal strength distribution of each floor.

[0078] For example: For the signal point to be detected in the k-th layer, the maximum signal strength corresponding to the signal point in the first row and first column is: The maximum signal strength corresponding to the signal point to be detected in the first row and second column is: The maximum signal strength corresponding to the signal point to be detected in the first row and Mth column is: The maximum signal strength corresponding to the signal point to be detected in the second row and first column is: The maximum signal strength corresponding to the signal point to be detected in the second row and second column is: The maximum signal strength corresponding to the signal point to be detected in the second row and Mth column is: The maximum signal strength corresponding to the signal point to be detected in the Nth row and first column is: The maximum signal strength corresponding to the signal point to be detected in the Nth row and second column is: The maximum signal strength corresponding to the signal point to be detected in the Nth row and Mth column is: Then the signal strength distribution corresponding to the k-th layer is: The same method can be used to obtain layers 1 through 2. The signal intensity distribution corresponding to the layer; by fusing the signal intensity distribution from layer 1 to layer 2. The signal strength distribution corresponding to each floor is used to obtain the signal strength distribution for a multi-story building. For example, the signal strength distribution for a multi-story building is as follows: ,in, The signal strength distribution corresponding to the first floor of a multi-story building; This represents the signal strength distribution corresponding to the k-th floor of a multi-story building. For multi-story buildings Signal intensity distribution corresponding to the layer.

[0079] Furthermore, a wireless signal heatmap is drawn based on the signal strength distribution corresponding to the multi-story building, including: obtaining multiple continuous color signal ranges based on preset minimum signal display value, preset maximum signal display value, and preset number of colors; each color signal range corresponds to a color value; determining the color signal range in which each signal strength is located in the signal strength distribution corresponding to the multi-story building, and then determining the color value corresponding to the color signal range as the color value corresponding to the signal strength, so as to obtain the wireless signal heatmap.

[0080] It should be noted that not all areas in a multi-story building require wireless access points. For example, elevator shafts and enclosed server rooms do not require wireless networks and therefore do not need access points. Consequently, signal strength in these locations is relatively weak. Displaying these areas on a heatmap could negatively impact subsequent wireless network planning. Therefore, a preset minimum signal strength is introduced as the preset effective signal value. Signal strength below this minimum value is considered invalid, indicating that the corresponding signal point to be detected is located in an area where wireless access points are not required.

[0081] The preset minimum signal strength is the preset valid signal value. If the signal strength is greater than or equal to this minimum value, the signal strength is considered valid and color display is allowed. If the signal strength is less than this minimum value, the signal strength is considered invalid and color display is not allowed. The preset minimum and maximum signal strength together constrain the signal strength for color display. The preset number of colors is the number of colors required to draw the wireless signal heatmap. The color value represents the colors needed to draw the wireless signal heatmap, and can be RGB (Red, Green, Blue), CMYK (Cyan, Magenta, Yellow, Black), or HSL (Hue, Saturation, Lightness) values.

[0082] In some embodiments, the preset minimum signal display value is Its value is The preset maximum signal display value is The preset number of colors is .Will to The signal strength range between them is divided into Segment. Through calculation , obtained the There are several color signal ranges. The first color signal range is... The second color signal range is ;…, No. The color signal range is ,Right now Each color signal range corresponds to a color value. In the signal strength distribution of a multi-story building, the color signal range of each signal strength is determined, and then the color value corresponding to that color signal range is determined as the color value corresponding to that signal strength, in order to obtain a wireless signal heatmap.

[0083] Furthermore, after drawing a wireless signal heat map corresponding to a multi-story building based on signal strength, the process also includes sending the wireless signal heat map to a preset display device to display the wireless signal heat map.

[0084] Combination Figure 3 As shown in the embodiments of this disclosure, another method for drawing a wireless signal heatmap is provided, the method comprising: Step S301: Obtain the first floor number of the first floor where the signal point to be detected is located; obtain the second floor number of the second floor where the wireless access point is located.

[0086] Step S303: Obtain the second coordinates corresponding to the wireless access point based on the second floor number; the second coordinates include the location of the wireless access point within the second floor and the second floor number.

[0087] Step S304: Obtain the number of traversed layers based on the first layer number and the second layer number.

[0088] Step S305: Obtain the floor height of each floor in a multi-story building.

[0089] Step S306: Convert the first coordinate to the third coordinate; the third coordinate is used to characterize the position of the signal to be detected in a multi-story building.

[0090] Step S307: Convert the second coordinate to the fourth coordinate; the fourth coordinate is used to characterize the location of the wireless access point in a multi-story building.

[0091] Step S308: Obtain the formula for the straight line corresponding to the signal propagation line based on the third and fourth coordinates.

[0092] Step S309: Determine the intersection point based on the floor height and the straight line formula.

[0093] Step S310: Determine whether each intersection point is within the preset hollow area.

[0094] Step S311: Calculate the number of intersections within the preset hollow area to obtain the number of hollow areas.

[0095] Step S312: Determine the number of floors the signal propagation line between the wireless access point and the signal point to be detected crosses based on the number of layers traversed and the number of open areas.

[0096] Step S313: Obtain the spatial distance between the wireless access point and the signal point to be detected.

[0097] Step S314: Obtain the signal strength based on the spatial distance and the number of floors crossed.

[0098] Step S315: Draw a wireless signal heat map corresponding to a multi-story building based on the signal strength.

[0099] In this way, the location and first coordinates of the signal under test within the first floor are determined based on the first floor number of the first floor where the signal point to be detected is located. The second coordinates of the location and second floor number of the wireless access point within the second floor are determined based on the second floor number of the second floor where the wireless access point is located. The number of floors traversed is obtained based on the first and second floor numbers. The floor heights of each floor in the multi-story building are obtained. Then, the first coordinates are converted into third coordinates representing the location of the signal under test within the multi-story building. The second coordinates are converted into fourth coordinates representing the location of the wireless access point within the multi-story building. The straight line formula corresponding to the signal propagation line is obtained based on the third and fourth coordinates. The intersection points are then determined using the straight line formula and the floor heights. The number of intersection points within a preset hollow area is accumulated to obtain the number of hollow areas. This leads to the number of floors traversed and the spatial distance. The signal strength is then obtained based on the spatial distance and the number of floors traversed, and a wireless signal heat map corresponding to the multi-story building is drawn. In this way, compared with the existing technology that uses on-site measurement or floor modeling to draw wireless signal heat maps, this application can accurately obtain the number of floors traversed and the number of hollow areas between the wireless access point and the signal point to be detected in a preset multi-story building by using the first coordinates corresponding to the signal point to be detected and the second coordinates corresponding to the wireless access point. Then, based on the number of floors traversed and the number of hollow areas, the signal strength of the wireless access point at the signal point to be detected can be accurately obtained. Without the need for on-site measurement of signal strength, the signal strength can be accurately calculated, so as to accurately draw the wireless signal heat map corresponding to the multi-story building based on the accuracy of the signal strength. This realizes the automatic drawing of the wireless signal heat map corresponding to the multi-story building, and thus achieves accurate visualization of the signal strength distribution. In this way, the accuracy of the wireless signal heat map of the multi-story building can be improved while saving manpower and resources.
