Description

Technical Field

[0001] This application relates to the field of communication engineering technology, and particularly to a signal tower site selection method, system and storage medium based on big data. Background Art

[0002] With the rapid development of communication technology, as an important part of the wireless communication network, the site selection of signal towers has become increasingly important. Traditional signal tower site selection mainly relies on manual experience judgment, geographical environment factor analysis and simple data statistics. These methods often lack comprehensiveness and accuracy. In recent years, the rapid development of big data technology has provided new ideas and methods for signal tower site selection. Big data technology can process and analyze massive data, mine the correlation and regularity between data, and provide more scientific and accurate decision-making support for signal tower site selection.

[0003] A similar prior art is the Chinese patent application with the publication number CN118690904A, which discloses a tower crane type selection planning method, device, computing device and storage medium. The method includes: collecting historical construction project data and tower crane foundation data, and constructing a project tower crane type selection data set; training a tower crane type selection model according to the project tower crane type selection data set to obtain a trained tower crane type selection model; obtaining the project data of the target construction project, and inputting the project data of the target construction project into the trained tower crane type selection model to obtain a tower crane type selection plan matching the target construction project. Although this application can improve the efficiency of tower crane type selection, it does not consider the accuracy of signal tower site selection.

[0004] Another similar prior art is the Chinese patent application with the publication number CN115578654A, which provides a method for identifying the type of transmission line pole tower based on point cloud, including making a pole tower type data set, converting a standard pole tower model into an image file with the same height and width, and establishing a standard pole tower character library; extracting the point cloud of the transmission pole tower, removing the miscellaneous points and wire point clouds contained in the point cloud measured by the unmanned aerial vehicle, and extracting the point cloud of the power pole tower; calculating the symmetry axis plane of the pole tower, calculating the symmetry axis plane of the measured point cloud of the pole tower by counting the number of points in each angular direction; re-projecting the measured point cloud of the pole tower onto the symmetry axis plane of the pole tower by using the coordinate transformation method; and identifying the type of the pole tower by using the template matching method. Although this invention improves the automation level of processing the point cloud data of the transmission line, it also does not consider the accuracy of signal tower site selection. Summary of the Invention

[0005] To solve the above technical problems, this application provides a signal tower site selection method, system and storage medium based on big data, which are used to improve the site selection efficiency and accuracy of signal towers.

[0006] In the first aspect, this application provides a signal tower site selection method based on big data, and the method includes:

[0007] Step S1: Based on the positions, signal strengths, and user complaint data of existing signal towers, obtain the siting range of the target signal tower, draw it into a two-dimensional map, divide the two-dimensional map into multiple regions, and obtain the constructible regions of the target signal tower from the multiple regions.

[0008] Step S2: Calculate the constructible positions of the target signal tower in each constructible region, obtain the geographical coordinates of the constructible positions in the region, based on the geographical information data and the geographical coordinates of the constructible positions, obtain the base height of the constructible positions, and calculate the signal emission height of the target signal tower based on the base height of the constructible positions and the preset tower height of the target signal tower.

[0009] Step S3: Based on the signal emission height of the target signal tower, test the signal reception strength of other regions in the siting range except the region where the target signal tower is located, and also test the ratio of the number of regions that meet the preset signal reception strength in the siting range to the total number of regions in the siting range as the effective coverage rate of the target signal tower.

[0010] Step S4: Select the regions that meet the preset effective coverage rate from the effective coverage rates of multiple target signal towers as the construction addresses of the target signal tower, and also use the constructible positions as the specific positions in the construction addresses of the target signal tower.

[0011] Combined with the first aspect, in the first implementation manner of the first aspect of the present application, after step S4, it further includes:

[0012] Step S5: There are multiple preset tower heights for the target signal tower. Change the preset tower heights in ascending order, and calculate the effective coverage rate of the target signal tower in each constructible region under each preset tower height to determine the final tower height of the target signal tower at the construction address.

[0013] Combined with the first aspect, in the second implementation manner of the first aspect of the present application, calculating the constructible positions of the target signal tower in each constructible region in step S2 includes:

[0014] Take any one of the constructible regions as the first region. If there is one or more building facilities available for building a signal tower in the first region, select the building facility with the highest height among the building facilities as the constructible position of the first region. If not, determine whether the difference between the highest point and the lowest point in the first region is less than a preset threshold. If it is less, use GIS software to calculate the constructible position of the first region. Otherwise, select the highest point in the first region as the constructible position of the first region.

[0015] In combination with the first aspect, in the third implementation manner of the first aspect of the present application, in step S2, obtaining the base height of the constructible location includes:

[0016] If the constructible location is a building facility, the base height is equal to the ground height plus the height of the building facility; otherwise, the base height is equal to the ground height, where the ground height refers to the vertical distance above sea level.

[0017] In combination with the first aspect, in the fourth implementation manner of the first aspect of the present application, step S1 further includes:

[0021] In combination with the first aspect, in the fifth implementation manner of the first aspect of the present application, step S4 further includes:

[0022] Obtaining constructible locations within the selected site range. If there is no building facility higher than the target signal tower between the constructible area closest to the constructible location and the constructible location, setting the priority of the constructible area closest to the constructible location to level one; otherwise, setting the priority of the constructible area closest to the constructible location to level two;

[0023] Setting the priority of the constructible area with the highest effective coverage rate of the target signal tower to level two, setting the priority of the constructible area with the lowest preset tower height of the target signal tower to level three, and setting the priority of other constructible areas other than those with the priority already set to level four;

[0024] On the two-dimensional map, mark the levels of the priorities of the buildable areas in the areas corresponding to the respective priorities, and select the construction site of the target signal tower based on the priorities of the buildable areas.

[0025] Combined with the first aspect, in the sixth implementation manner of the first aspect of the present application, the step S4 further includes:

[0026] If the construction of the target signal tower is restricted at the buildable positions in the area where the construction site is located, then select a second construction position in the area, and re-measure the effective coverage rate of the second construction position based on the preset tower height of the target signal tower. When the effective coverage rate of the second construction position is greater than or equal to the preset effective coverage rate, use the second construction position as the final construction position of the target signal tower; otherwise, use the buildable positions in the area where the construction site is located as the final construction position of the target signal tower.

[0027] Combined with the first aspect, in the seventh implementation manner of the first aspect of the present application, the step S4 further includes:

[0028] Take any one of the buildable areas as the second area. When installing the first target signal tower at the buildable positions in the second area, if the area where the effective coverage rate of the first target signal tower is greater than or equal to the preset effective coverage rate is less than or equal to 1 / N of the site selection range area, then select a third area from the buildable areas to build a second target signal tower, where the second target signal tower is one or more, and N represents a positive integer greater than or equal to 2 and less than 10;

[0029] Combine the first target signal tower and the second target signal tower, and re-measure the total effective coverage rate. When the total effective coverage rate is greater than or equal to the preset effective coverage rate, use the second area as the construction site of the first target signal tower, and use the third area as the construction site of the second target signal tower.

[0030] In a second aspect, the present application provides a signal tower site selection system based on big data, and the system includes:

[0035] The third aspect of the present application provides a computer-readable storage medium, in which instructions are stored, and when it runs on a computer, it causes the computer to execute the above-mentioned signal tower site selection method based on big data.

[0036] Compared with the prior art, the beneficial effects of the present invention are at least as follows:

[0038] By calculating the constructible positions of the target signal towers in each constructible area, obtaining the geographical coordinates of the constructible positions in the area, based on the geographical information data and the geographical coordinates of the constructible positions, obtaining the base height of the constructible positions, and based on the base height of the constructible positions and the preset tower height of the target signal tower, calculating the signal emission height of the target signal tower, it can ensure that the signal coverage range of the signal tower meets the expectation and improve the signal transmission effect. Based on the signal emission height of the target signal tower, testing the signal reception strength of other areas in the selected site range except the area where the target signal tower is located, and also testing the ratio of the number of areas that meet the preset signal reception strength in the selected site range to the total number of areas in the selected site range as the effective coverage rate of the target signal tower, it can quantify the coverage effect of the signal tower, select the optimal construction position, and ensure the maximization of the signal coverage range.

[0039] By selecting the area that meets the preset effective coverage rate from the effective coverage rates of multiple target signal towers as the construction site of the target signal tower, and taking the constructible location as the specific location in the construction site of the target signal tower, the optimal construction location for the signal tower is selected to ensure the accuracy of the signal tower site selection. Through the cooperation between the above steps, the optimal construction location for the signal tower can be selected to ensure the accuracy of the signal tower site selection. At the same time, the calculation amount during testing is reduced, and the site selection efficiency of the signal tower is improved. Description of the Drawings

[0046] Embodiment 1:

[0047] For ease of understanding, the specific process of the embodiments of the present application will be described below. Please refer to Figure 1 An embodiment of the method for locating a signal tower based on big data in the embodiments of the present application includes:

[0048] Step S1: Based on the positions, signal strengths, and user complaint data of existing signal towers, obtain the siting range of the target signal tower, draw it into a two-dimensional map, divide the two-dimensional map into multiple regions, and obtain the constructible regions of the target signal tower from the multiple regions.

[0049] Specifically, to improve the siting efficiency of the signal tower, assume that a new signal tower needs to be built in City A. Through big data analysis of the data of existing signal towers and user complaints, it is found that the signal coverage in the eastern region of the city is insufficient and there are many complaints. The areas with insufficient signal coverage are marked with points on the two-dimensional map, and finally all the points are connected to form the range to be covered by the new signal tower. By determining the siting range of the target signal tower, resources can be prevented from being wasted in areas with good signal coverage. As Figure 2 shown, A1, A2, A3, A4, A5, A6, A7, and A8 are areas with insufficient signal coverage. By connecting A1, A2, A3, A4, A5, A6, A7, and A8 together, the range 100 to be covered by the signal tower is formed. To further ensure the coverage range of the signal tower, during calculation, the range to be covered by the signal tower will be expanded, that is, the range 200 is used as the siting range of the target signal tower. Among them, the method of expanding the range to be covered by the signal tower is not limited, and it extends several meters or hundreds of meters outward based on including places with insufficient signal coverage of other signal towers. After that, the siting range of the target signal tower is also divided into multiple numbered regions, such as region ①, region ②, etc., and marked on the map. The numbers can be unordered but cannot be repeated. The constructible regions, such as parks, open spaces, etc., are also selected from these regions, and the regions where signal towers cannot be built are screened out, reducing the calculation amount for calculating the coverage rate of the signal tower in the next step, thereby improving the siting efficiency.

[0050] Step S2: Calculate the constructible positions of the target signal tower in each constructible region, obtain the geographical coordinates of the constructible positions in the region, based on the geographical information data and the geographical coordinates of the constructible positions, obtain the base height of the constructible positions, and calculate the signal emission height of the target signal tower based on the base height of the constructible positions and the preset tower height of the target signal tower.

[0051] Specifically, in the selected constructible area, geographical coordinates of each location are obtained using Geographic Information System (GIS) tools. Meanwhile, the base height of each location is obtained through topographic maps or on-site measurements. For example, the geographical coordinates of a certain location in Area 1 are (34.0522, -118.2437), and the base height is 100 meters. Obtaining the geographical coordinates and base height of each constructible location can ensure the accuracy of the signal tower construction location, and the base height data helps in subsequent calculations of the signal emission height, improving the accuracy of signal coverage.

[0052] Assume the preset tower height is 30 meters and the base height is 100 meters, then the signal emission height is 130 meters. Since the base heights of different terrains vary, the signal tower is built on top of the base height, and adding the preset tower height of the signal tower gives the accurate signal emission height. Therefore, when considering the signal emission height, not only the height of the signal tower itself but also the base height of the location where the signal tower is built should be considered.

[0053] Step S3: Based on the signal emission height of the target signal tower, test the signal reception strength in other areas within the selected site except the area where the target signal tower is located, and also test the ratio of the number of areas within the selected site that meet the preset signal reception strength to the total number of areas within the selected site as the effective coverage rate of the target signal tower.

[0054] Specifically, install temporary signal emission equipment at each constructible location, test the signal propagation within the selected site, and record the signal reception strength at each location. For example, the signal reception strength at a certain location in Area 1 is -70 dBm, and the signal reception strength at a certain location in Area 2 is -80 dBm, etc. By testing signal propagation at each constructible location, the signal coverage effect of different locations can be evaluated, and the best construction location can be selected to ensure that the signal reception strength meets the preset standard.

[0055] Assume there are a total of 100 areas within the selected site, and the signal reception strength of 80 areas meets the preset standard (such as above -75 dBm), then the effective coverage rate is 80%. Select the area with the highest effective coverage rate as the construction site. By calculating the effective coverage rate, the coverage effect of the signal tower can be quantified, and the optimal construction location can be selected to ensure the maximum signal coverage range.

[0056] Step S4: Select the areas that meet the preset effective coverage rate from the effective coverage rates of multiple target signal towers as the construction sites of the target signal towers, and also use the constructible locations as the specific locations within the construction sites of the target signal towers.

[0057] Specifically, among multiple candidate locations, the area with the highest effective coverage rate is selected as the construction site. For example, the effective coverage rate of Area 1 is 85%, and that of Area 2 is 80%. Finally, Area 1 is selected as the construction site. The specific location is the constructible location with the highest signal reception strength, such as a certain location in Area 1.

[0058] Through the coordination among the above steps, the signal tower site selection method based on big data can select the optimal construction location for the signal tower, ensuring the accuracy of signal tower site selection. At the same time, it also reduces the computational amount during testing and improves the signal tower site selection efficiency.

[0059] Furthermore, in Specific Embodiment 1, after Step S4, it further includes:

[0060] Step S5: There are multiple preset tower heights for the target signal tower. The preset tower height is changed from low to high in sequence, and the effective coverage rate of the target signal tower in each constructible area under each preset tower height is calculated to determine the final tower height of the target signal tower at the construction site.

[0061] Specifically, assume that there are multiple preset tower heights for the target signal tower, which are 30 meters, 50 meters, and 80 meters respectively. We will change the preset tower height from low to high in sequence and calculate the effective coverage rate under each tower height to determine the final tower height. For example, when the preset tower height is 30 meters, repeat Steps S3 to S5 to calculate the signal emission height, signal propagation, and effective coverage rate in each constructible area. Assume that the effective coverage rate of this construction site under the 30 - meter tower height is 80%; when the preset tower height is 50 meters: recalculate the signal emission height, signal propagation, and effective coverage rate in each constructible area. Assume that under the 50 - meter tower height, the effective coverage rate of the construction site is 85%; when the preset tower height is 80 meters: Steps S3 to S5 will be repeated again to calculate the signal emission height, signal propagation, and effective coverage rate in each constructible area. Assume that under the 80 - meter tower height, the effective coverage rate of the construction site is 86%.

[0062] Although the effective coverage rate of the 80 - meter tower height is 86%, which is slightly higher than 85% of the 50 - meter tower height, the coverage improvement brought by increasing the tower height by 30 meters is relatively small. At the same time, the construction cost and maintenance cost of the 80 - meter tower height will increase significantly. Considering the cost and coverage effect comprehensively, choosing the 50 - meter tower height as the final tower height can control the construction cost and maintenance cost while meeting the coverage requirements.

[0063] The above steps can determine the final tower height that can achieve the best coverage effect at the construction site by gradually changing the preset tower height and calculating the effective coverage rate under each tower height. This method not only ensures that the signal tower can be built at the optimal location but also optimizes the cost - benefit and saves the construction cost of the signal tower.

[0064] Further, in the first specific embodiment, calculating the constructible positions of the target signal towers in each constructible area in step S2 includes:

[0065] Taking any one area in the constructible area as the first area. If there is one or more building facilities in the first area that can be used to build a signal tower, select the building facility with the highest height among the building facilities as the constructible position of the first area. If not, determine whether the difference between the highest point and the lowest point in the first area is less than a preset threshold. If it is less, use GIS software to calculate the constructible position of the first area. Otherwise, select the highest point in the first area as the constructible position of the first area.

[0066] Specifically, taking any one area in the constructible area as the first area, it is necessary to further determine the constructible position within this area. The specific steps are as follows: Check the building facilities, including the location and height of the buildings. There are building facilities: If there is one or more building facilities in the first area that can be used to build a signal tower, select the building facility with the highest height among these building facilities as the constructible position. For example, if there are three buildings in the area with heights of 20 meters, 30 meters, and 40 meters respectively, select the building with a height of 40 meters as the constructible position. Without building facilities: If there are no building facilities in the first area that can be used to build a signal tower, proceed to the next step and judge the terrain height difference: Calculate the height difference between the highest point and the lowest point in the first area. If this difference is less than a preset threshold (for example, 15 meters), use GIS software to calculate the constructible position of this area. GIS software can comprehensively consider factors such as the flatness of the terrain and traffic convenience to select an optimal position. For example, the highest point in the area is 10 meters, the lowest point is -5 meters, and the height difference is 15 meters, which is less than the preset threshold, so use GIS software to calculate the constructible position. The height difference is greater than or equal to the preset threshold: If the height difference is greater than or equal to the preset threshold, select the highest point in the first area as the constructible position. For example, the highest point in the area is 50 meters, the lowest point is 10 meters, and the height difference is 40 meters, which is greater than the preset threshold, so select the highest point as the constructible position.

[0067] By analyzing in detail the building facilities and terrain height in each constructible area, the optimal constructible position of each area can be accurately determined. This method accurately locates the construction position of the signal tower, and while improving the signal coverage effect, it also considers how to save the construction cost of the signal tower.

[0068] Further, in the first specific embodiment, in step S2 above, obtaining the base height of the constructible position includes:

[0069] If the buildable location is a building facility, the base height is equal to the ground height plus the height of the building facility; otherwise, the base height is equal to the ground height, where the ground height refers to the vertical distance above sea level.

[0070] Specifically, assuming that the buildable locations within a certain buildable area have been determined, the next step is to obtain the base height of each location. The specific steps are as follows: If the buildable location is on a building facility, obtain the height of the building facility and the ground height. Assume that the buildable location is a building with a height of 40 meters and the ground height is 10 meters. Then the base height = ground height + height of the building facility = 10 meters + 40 meters = 50 meters. If the buildable location is natural terrain, only obtain the ground height, and the base height = ground height = 10 meters. Through this step, the base height of each buildable location can be accurately calculated. This not only ensures the accurate calculation of the signal transmission height of the signal tower but also improves the accuracy of signal coverage. By distinguishing the types of buildable locations, different situations can be handled more precisely, improving the signal coverage effect while saving the construction cost of the signal tower.

[0071] Furthermore, in Specific Embodiment 1, the above step S1 further includes:

[0072] Obtain the land cover data within the site selection range based on the geographic information data. Based on the land cover data, determine the prohibited installation areas of signal towers within the site selection range, obtain the area numbers corresponding to the prohibited installation areas, and mark the area numbers corresponding to the prohibited installation areas on the two-dimensional map with the first color. The land cover data includes shopping malls, residential areas, schools, office buildings, industrial areas, rivers, lakes, mountains, and green spaces.

[0073] Based on the geographic information system, obtain the signal interference devices within the site selection range and the area numbers corresponding to the areas where the signal interference devices are located, and mark the area numbers corresponding to the areas where the signal interference devices are located on the two-dimensional map with the second color.

[0074] Based on the prohibited installation areas and signal interference areas marked on the two-dimensional map, obtain the buildable areas for the target signal tower from multiple areas within the site selection range, and select the construction address of the target signal tower from the buildable areas.

[0075] Specifically, obtain the land cover data within the site selection range based on the geographic information data, including shopping malls, residential areas, schools, office buildings, industrial areas, rivers, lakes, mountains, and green spaces. According to the land cover data, determine the prohibited installation areas of signal towers within the site selection range, and mark the prohibited installation area numbers on the two-dimensional map with the first color, such as Figure 3The red-marked ①, ②, and ④ in [the figure] are areas such as schools, hospitals, rivers, and lakes, where signal towers are usually not allowed to be installed. Also based on the geographic information system, signal interference devices within the selected site range and the corresponding area numbers of the regions where they are located are obtained. Signal interference devices may include other communication base stations, radar stations, etc. The area numbers corresponding to the regions where the signal interference devices are located are marked on the two-dimensional map with a second color, such as Figure 3 the yellow-marked ③ and ⑤ in [the figure]. After excluding the prohibited installation areas and signal interference areas from the selected site range, the constructible areas for the target signal tower are obtained. For example, the area numbers ⑥, ⑦, and ⑧ of an empty area can all be used as construction sites. Through this step, the prohibited installation areas and signal interference areas within the selected site range can be accurately determined and marked on the two-dimensional map. To avoid building signal towers in unsuitable areas, for testing the signal propagation of the target signal tower, calculating the effective coverage effect reduces the amount of calculation, thereby improving the site selection efficiency.

[0076] Furthermore, in Specific Embodiment 1, the above step S4 further includes:

[0077] Obtain the constructible positions within the selected site range. If there are no building facilities higher than the target signal tower between the constructible area closest to the constructible position and the constructible position, set the priority of the constructible area closest to the constructible position to level 1; otherwise, set the priority of the constructible area closest to the constructible position to level 2.

[0078] Set the priority of the constructible area with the highest effective coverage rate of the target signal tower to level 2, set the priority of the constructible area with the lowest preset tower height of the target signal tower to level 3, and set the priority of other constructible areas other than those with the priority already set to level 4.

[0079] On the two-dimensional map, mark the levels of the constructible area priorities in the regions corresponding to each priority, and select the construction site of the target signal tower based on the priorities of the constructible areas.

[0080] Specifically, the determined constructible areas in the above method include one or more constructible areas. Next, the final construction site needs to be selected according to the priorities. Obtain the constructible position coordinates of the selected site range, for example, Figure 3Among them, ⑦, the buildable location is relative to the selected site range or can be the exact center of the selected site range obtained through calculation. Assume that area ⑥ is the closest to the buildable location. Check whether there are any building facilities higher than the target signal tower between area ⑥ and the buildable location. If there are no building facilities higher than the target signal tower between area ⑥ and the buildable location, set the priority of area ⑥ to level one. Assume that the effective coverage rate of area ⑧ is 85%, which is the highest among all buildable areas. Set the priority of area B to level two. Assume that the preset tower height of area ⑥ is 30 meters, which is the lowest among all buildable areas. Also set the priority of area ⑥ to level three (including level one). Set the priorities of other areas to level four. Select the construction site of the target signal tower according to the priorities of the buildable areas. Prioritize area ⑥ with the highest priority as the construction site. Its priority is not only close to the buildable location, but also has the lowest tower height for construction, saving the most construction cost. Through the above steps, comprehensively consider multiple factors to set the priorities of the buildable areas to ensure that the selected construction site not only has a good coverage effect but also a low construction cost.

[0081] Further, in the first specific embodiment, the above step S4 further includes:

[0082] If it is restricted to build the target signal tower at the buildable location in the area where the construction site is located, then select a second construction location within the area and retest the effective coverage rate of the second construction location based on the preset tower height of the target signal tower. When the effective coverage rate of the second construction location is greater than or equal to the preset effective coverage rate, use the second construction location as the final construction location of the target signal tower; otherwise, use the buildable location in the area where the construction site is located as the final construction location of the target signal tower.

[0083] Specifically, assume that the area where a certain construction site is located has been determined, but the construction of signal towers at the available construction locations is restricted (for example, the available construction locations are protected areas, a small science popularization park). Next, it is necessary to select a second construction location within this area and retest the effective coverage rate. The specific steps are as follows: Obtain the information of the available construction locations in the area where the construction site is located. Assume that the available construction location ⑥ in the area where the construction site is located is a small science popularization park and signal tower construction is not allowed. At this time, other open spaces in this area, such as open spaces with convenient transportation, can be selected as the second construction location. Based on the preset tower height of the target signal tower selected in the above method, retest the effective coverage rate of the second construction location, and retest the effective coverage rate of the second construction location. If the effective coverage rate of the second construction location is greater than or equal to the preset effective coverage rate, then this location is used as the final construction location of the target signal tower. Assume that the preset effective coverage rate is 80%, and the effective coverage rate of the second construction location is 82%, which meets the preset effective coverage rate, and the second construction location is used as the final construction location. Of course, the third construction location, the fourth construction location, etc. can also be searched for in the current area according to this method. Through the above steps, the second construction location is flexibly selected within the area where the construction site is located and the effective coverage rate is retested, ensuring that even when the available construction locations are restricted, a construction location that meets the preset effective coverage rate can be found, improving the flexibility and accuracy of site selection and ensuring that the construction location of the signal tower can achieve the expected coverage effect.

[0084] Further, in Specific Embodiment 1, the above step S4 further includes:

[0085] Take any area in the available construction area as the second area. When installing the first target signal tower at the available construction locations in the second area, if the area where the effective coverage rate of the first target signal tower is greater than or equal to the preset effective coverage rate is less than or equal to 1 / N of the site selection range area, then select a third area from the available construction area to build the second target signal tower, and the second target signal tower is one or more, and N represents a positive integer greater than or equal to 2 and less than 10.

[0086] Combine the first target signal tower and the second target signal tower and retest the total effective coverage rate. When the total effective coverage rate is greater than or equal to the preset effective coverage rate, use the second area as the construction site of the first target signal tower and use the third area as the construction site of the second target signal tower.

[0087] Specifically, assume that among the determined multiple constructible areas, the coverage range of a certain signal tower is limited. At this time, it is necessary to evaluate the coverage effect of a single signal tower and select multiple signal towers for combination when necessary. The specific steps are as follows: Take any area in the constructible area as the second area, and install the first target signal tower at the constructible location in the second area. Test the effective coverage rate of the first target signal tower and check whether its coverage area is greater than or equal to the area of the preset effective coverage rate. For example, in the second area, after installing the first target signal tower, it is found that its effective coverage area is 1 / 5 of the selected site area, and the preset effective coverage rate is 80%. If the effective coverage area of the first target signal tower is less than or equal to 1 / N of the selected site area, then select the third area from the constructible areas to build the second target signal tower. Assume N = 5, and the effective coverage area of the first target signal tower is 1 / 5 of the selected site area, then select the third area. Combine the first target signal tower and the second target signal tower. Test the total effective coverage rate after combination and check whether it is greater than or equal to the preset effective coverage rate. Assume that after combining the first target signal tower and the second target signal tower, the total effective coverage rate is 85%, which is greater than the preset effective coverage rate of 80%. If the total effective coverage rate is greater than or equal to the preset effective coverage rate, then take the second area as the construction address of the first target signal tower and the third area as the construction address of the second target signal tower. Through the above steps, the coverage effect of a single signal tower can be evaluated, and multiple signal towers can be selected for combination when necessary to ensure that the signal coverage rate within the entire selected site reaches the preset standard.
