Description

TECHNICAL FIELD

[0001] The application relates to the technical field of communication engineering, and in particular relates to a signal tower site selection method and system based on big data and a storage medium. BACKGROUND

[0002] With the rapid development of communication technology, the site selection of signal towers, as an important part of wireless communication networks, has become increasingly important. Traditional signal tower site selection mainly relies on manual experience judgment, geographical environment factor analysis, and simple data statistics, which 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 amounts of data, uncovering the relevance and regularity between data, and providing more scientific and accurate decision support for signal tower site selection.

[0003] A similar prior art is Chinese patent application No. CN118690904A, which discloses a tower type selection planning method and device, computing equipment, and storage medium. The method includes: collecting historical construction project data and tower foundation data to construct a project tower type selection dataset; training a tower type selection model based on the project tower type selection dataset to obtain a trained tower type selection model; obtaining project data of a target construction project and inputting the project data of the target construction project into the trained tower type selection model to obtain a tower type selection scheme matching the target construction project. Although this application can improve the efficiency of tower type selection, it does not consider the accuracy of signal tower site selection.

[0004] A similar prior art is Chinese patent application No. CN115578654A, which provides a power transmission pole tower type identification method based on point cloud. The method includes: making a pole tower type dataset, converting a standard pole tower model into a consistent height and width image file, and establishing a standard pole tower character library; extracting power pole tower point cloud by removing miscellaneous points and wire point cloud from unmanned aerial vehicle measurement point cloud; calculating the symmetric axis plane of the pole tower measurement point cloud by counting the number of points in each angle direction; projecting the pole tower measurement point cloud onto the symmetric axis plane using coordinate transformation; and identifying the pole tower type using a template matching method. Although this invention improves the automation level of power transmission line point cloud data processing, it also does not consider the accuracy of signal tower site selection. SUMMARY

[0046] Embodiment one:

[0047] For ease of understanding, the specific process of the embodiments of the present application is described below. Please refer to Figure 1 One embodiment of the signal tower site selection method based on big data in the embodiments of the present application includes:

[0048] Step S1: Based on the location, signal strength and user complaint data of the existing signal tower, the site selection range of the target signal tower is obtained and drawn into a two-dimensional map. The two-dimensional map is divided into multiple regions, and the constructable region of the target signal tower is obtained from the multiple regions.

[0049] Specifically, in order to improve the site selection efficiency of the signal tower, it is assumed that a new signal tower needs to be built in city A. By analyzing the data of the existing signal tower and user complaints through big data, it is found that the signal coverage in the eastern region of the city is insufficient, and there are more complaints. The areas with insufficient signal coverage are marked on the two-dimensional map with points. Finally, all the points are connected to form the range to be covered by the newly built signal tower. By determining the site selection range of the target signal tower, resources can be saved in areas with good signal coverage. As shown in Figure 2 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. In order to further ensure the coverage range of the signal tower, the range to be covered by the signal tower is expanded during calculation, i.e. the range 200 is taken as the site selection range of the target signal tower. The method of expanding the range to be covered by the signal tower is not limited, and the range is extended by several meters or several hundred meters outward to include other areas with insufficient signal coverage. Then the site selection range of the target signal tower is divided into multiple numbered regions, such as region ①, region ②, etc., and marked on the map. The numbering can be unordered but cannot be repeated. The constructable regions such as parks and open spaces are also selected from these regions, and the regions where the signal tower cannot be constructed are selected. This reduces the calculation amount for calculating the coverage rate of the signal tower in the next step, thereby improving the site selection efficiency.

[0050] Step S2: Calculate the constructable position of the target signal tower in each constructable region, and obtain the geographic coordinates of the constructable position in the region. Based on the geographic information data and the geographic coordinates of the constructable position, the basic height of the constructable position is obtained. Based on the basic height of the constructable position and the preset tower height of the target signal tower, the signal emission height of the target signal tower is calculated.

[0051] Specifically, in the selected buildable area, geographic coordinates of each location are obtained using geographic information system (GIS) tools. At the same time, the base height of each location is obtained through topographic maps or field measurements. For example, the geographic coordinates of a certain location in Area 1 are (34.0522, -118.2437) and the base height is 100 meters. Obtaining the geographic coordinates and base height of each buildable location can ensure the accuracy of the signal tower construction location, and the base height data can help subsequent calculation of signal transmission height, improving the accuracy of signal coverage.

[0052] Assuming the preset tower height is 30 meters and the base height is 100 meters, the signal transmission height is 130 meters. Since the base height of the land varies from place to place, the signal tower is built on the base height, plus the preset signal tower height, which is the accurate signal transmission height. Therefore, when considering the signal transmission height, not only the height of the signal tower itself should be considered, but also the base height of the address where the signal tower is built.

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

[0054] Specifically, temporary signal transmission equipment is installed at each buildable location, the signal propagation in the site selection range is tested, and the signal reception strength of each location is recorded, for example, the signal reception strength of a certain location in Area 1 is -70 dBm, and the signal reception strength of a certain location in Area 2 is -80 dBm, etc. By testing signal propagation at each buildable location, the signal coverage effect of different locations can be evaluated, the best construction location can be selected, and the signal reception strength can be ensured to meet the preset standard.

[0055] Assuming that there are a total of 100 areas in the site selection range, and the signal reception strength of 80 areas meets the preset standard (such as -75 dBm or above), the effective coverage rate is 80%. The area with the highest effective coverage rate is selected as the construction address. By calculating the effective coverage rate, the coverage effect of the signal tower can be quantified, the optimal construction location can be selected, and the signal coverage range can be maximized.

[0056] Step S4: From the effective coverage rates of multiple target signal towers, select an area that meets the preset effective coverage rate as the construction address of the target signal tower, and also select the buildable location as a specific location in the target signal tower construction address.

[0057] Specifically, among the multiple candidate locations, the area with the highest effective coverage rate is selected as the construction address. For example, the effective coverage rate of area 1 is 85%, and the effective coverage rate of area 2 is 80%, and finally area 1 is selected as the construction address. The specific location selects the location with the highest signal receiving strength, such as a certain location in area 1.

[0058] Through the cooperation between the above steps, the signal tower site selection method based on big data can select the optimal construction location for the signal tower, ensure the accuracy of the signal tower site selection, and at the same time reduce the calculation amount during testing, and improve the efficiency of the signal tower site selection.

[0059] Further, in embodiment one, after step S4, it further includes:

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

[0061] Specifically, assuming that the target signal tower has multiple preset tower heights, 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, the preset tower height is 30 meters, repeat steps S3 to S5, calculate the signal transmission height, signal propagation and effective coverage rate in each construction area, assuming that the effective coverage rate of the construction address under the 30-meter tower height is 80%; the preset tower height is 50 meters: recalculate the signal transmission height, signal propagation and effective coverage rate in each construction area, assuming that the effective coverage rate of the construction address under the 50-meter tower height is 85%; the preset tower height is 80 meters: steps S3 to S5 will be repeated again, and the signal transmission height, signal propagation and effective coverage rate in each construction area are calculated, assuming that the effective coverage rate of the construction address under the 80-meter tower height is 86%.

[0062] Although the effective coverage rate of the 80-meter tower height is 86%, which is slightly higher than the 85% of the 50-meter tower height, the coverage improvement brought by the increase of 30 meters of tower height is relatively small, and 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, the 50-meter tower height is selected as the final tower height, which can meet the coverage requirement while controlling the construction cost and maintenance cost.

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

[0064] Further, in the first embodiment, the step S2 of calculating the buildable position of the target signal tower in each buildable region comprises:

[0065] Taking any one of the buildable regions as a first region, if there is one or more building facilities available for building a signal tower in the first region, selecting the building facility with the highest height as the buildable position of the first region, if not, judging whether the difference between the highest point and the lowest point in the first region is less than a preset threshold, if yes, using GIS software to calculate the buildable position of the first region, otherwise selecting the highest point in the first region as the buildable position of the first region.

[0066] Specifically, taking any one of the buildable regions as a first region, the buildable position in this region needs to be further determined, and the specific steps are as follows: checking the building facilities, including the positions and heights of the buildings. Building facilities: if there is one or more building facilities available for building a signal tower in the first region, selecting the building facility with the highest height as the buildable position. For example, there are three buildings in the region, with heights of 20 meters, 30 meters and 40 meters, respectively, and the building with a height of 40 meters is selected as the buildable position. No building facilities: if there is no building facility available for building a signal tower in the first region, go to the next step, judge the terrain height difference: calculate the height difference between the highest point and the lowest point in the first region. If the difference is less than a preset threshold (for example, 15 meters), use GIS software to calculate the buildable position of the region. The GIS software can comprehensively consider the flatness of the terrain, traffic convenience and other factors to select an optimal position. For example, the highest point in the region is 10 meters, the lowest point is -5 meters, and the height difference is 15 meters, which is less than the preset threshold, and the GIS software is used to calculate the buildable position. Height difference 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 region as the buildable position. For example, the highest point in the region is 50 meters, the lowest point is 10 meters, and the height difference is 40 meters, which is greater than the preset threshold, and the highest point is selected as the buildable position.

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

[0068] Further, in the first embodiment, the step S2 of calculating the buildable position of the target signal tower in each buildable region comprises:

[0069] If the constructable location is a building facility, the foundation height is equal to the ground height plus the height of the building facility, otherwise, the foundation height is equal to the ground height, wherein the ground height refers to the vertical distance above the sea level.

[0070] Specifically, assuming that the constructable location in a certain constructable area has been determined, the foundation height of the location needs to be obtained next. The specific steps are as follows: if the constructable location is on a building facility, the height of the building facility and the ground height are obtained. Assuming that the constructable location is a building with a height of 40 meters and the ground height is 10 meters, the foundation height = ground height + height of building facility = 10 meters + 40 meters = 50 meters. If the constructable location is a natural terrain, only the ground height is obtained, and the foundation height = ground height = 10 meters. Through this step, the foundation height of each constructable location can be accurately calculated. This not only ensures the accuracy of the signal tower signal transmission height calculation, but also improves the accuracy of signal coverage. By distinguishing the types of constructable locations, different situations can be handled more finely, which not only improves the signal coverage effect, but also saves the construction cost of signal towers.

[0071] Further, in embodiment one, the above step S1 further comprises:

[0072] Based on the geographic information data, land cover data in the site selection range is obtained, based on the land cover data, the prohibited installation area of the signal tower in the site selection range is determined, the region number corresponding to the prohibited installation area is obtained, and the region number corresponding to the prohibited installation area is marked on the two-dimensional map with a first color. The land cover data includes shopping malls, residential areas, schools, office buildings, industrial areas, rivers, lakes, mountainous areas and green lands.

[0073] Based on the geographic information system, signal interference equipment in the site selection range and the region number corresponding to the signal interference equipment are obtained, and the region number corresponding to the signal interference equipment is marked on the two-dimensional map with a second color.

[0074] Based on the prohibited installation area and the signal interference area marked on the two-dimensional map, the constructable area of the target signal tower is obtained from the multiple regions in the site selection range, and the construction address of the target signal tower is selected from the constructable area.

[0075] Specifically, based on the geographic information data, land cover data in the site selection range is obtained, including shopping malls, residential areas, schools, office buildings, industrial areas, rivers, lakes, mountainous areas and green lands. According to the land cover data, the prohibited installation area of the signal tower in the site selection range is determined, and the region number corresponding to the prohibited installation area is marked on the two-dimensional map with a first color, such as Figure 3The red mark ①, ② and ④ in the figure is the area of school, hospital, river, lake, etc. These areas are usually not allowed to install signal towers. Based on geographic information system, the signal interference equipment in the site selection range and the corresponding area number of the area where the signal interference equipment is located are obtained. The signal interference equipment may include other communication base stations, radar stations, etc. The corresponding area number of the area where the signal interference equipment is located is marked on the two-dimensional map with a second color, such as Figure 3 The yellow mark ③ and ⑤ in the figure. After excluding the prohibited installation area and signal interference area in the site selection range, the constructible area of the target signal tower is obtained, for example, an empty area number ⑥, ⑦, ⑧ can be selected as the construction address. Through this step, the prohibited installation area and signal interference area in the site selection range can be accurately determined and marked on the two-dimensional map. In order to avoid building signal towers in unsuitable areas, to test the signal propagation of the target signal tower, to reduce the calculation amount of effective coverage calculation, and to improve the site selection efficiency.

[0076] Further, in embodiment one, the above step S4 further comprises:

[0077] Obtain the constructible position of the site selection range. If there is no building facility higher than the target signal tower between the nearest constructible area to the constructible position and the constructible position, the priority of the nearest constructible area to the constructible position is set to level one, otherwise, the priority of the nearest constructible area to the constructible position is set to level two.

[0078] The priority of the constructible area with the highest effective coverage rate of the target signal tower is set to level two, the priority of the constructible area with the lowest preset tower height of the target signal tower is set to level three, and the priority of other constructible areas except the areas with set priority is set to level four.

[0079] On the two-dimensional map, the level of the priority of the constructible area is marked in the area corresponding to each priority, and the construction address of the target signal tower is selected based on the priority of the constructible area.

[0080] Specifically, the constructible area determined in the above method includes one or more constructible areas, and then the final construction address needs to be selected according to the priority. Obtain the coordinates of the constructible position of the site selection range, such as Figure 3In the above step S4, the construction location is relative to the site selection range, or is the center of the site selection range obtained by calculation. Assuming that the region ⑧ is closest to the construction location, it is checked whether there is a building facility higher than the target signal tower between the region ⑧ and the construction location. If there is no building facility higher than the target signal tower between the region ⑧ and the construction location, the priority of the region ⑧ is set to level one. Assuming that the effective coverage rate of the region ⑧ is 85%, which is the highest among all the construction regions, the priority of the region ⑧ is set to level two. Assuming that the preset tower height of the region ⑧ is 30 meters, which is the lowest among all the construction regions, the priority of the region ⑧ is set to level three (also including level one) at the same time, and the priorities of the other regions are set to level four. The construction address of the target signal tower is selected according to the priorities of the construction regions. The region ⑧ with the highest priority is preferentially selected as the construction address, which is not only closest to the construction location, but also has the lowest tower height and the lowest construction cost. Through the above steps, the priorities of the construction regions are set by comprehensively considering multiple factors, so as to ensure that the selected construction address not only has good coverage effect, but also has low construction cost.

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

[0082] If the construction of the target signal tower at the construction location of the region is limited, a second construction location is selected in the region, and the effective coverage rate of the second construction location is retested 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, the second construction location is taken as the final construction location of the target signal tower, otherwise the construction location of the region is taken as the final construction location of the target signal tower.

[0083] Specifically, assuming that the region where the construction address is located has been determined, but the construction of the signal tower is limited in the constructible location (for example, the constructible location is a protected area, a small science popularization park), the next step is to select a second construction location in the region and retest the effective coverage rate, the specific steps are as follows: obtaining the constructible location information of the region where the construction address is located, assuming that the constructible location ⑥ of the region where the construction address is located is a small science popularization park, which does not allow the construction of a signal tower, at this time, other open spaces in the region can be selected as the second construction location, such as open spaces with convenient transportation. Based on the preset tower height of the target signal tower selected in the above method, the effective coverage rate of the second construction location is retested. If the effective coverage rate of the second construction location is greater than or equal to the preset effective coverage rate, the location is taken as the final construction location of the target signal tower. Assuming that the preset effective coverage rate is 80%, the effective coverage rate of the second construction location is 82%, which meets the preset effective coverage rate, and the second construction location is taken as the final construction location. Of course, according to the method, a third construction location, a fourth construction location, etc. can be continuously searched in the current region. Through the above steps, the second construction location is flexibly selected in the region where the construction address is located and the effective coverage rate is retested, ensuring that even in the case of limited constructible location, a construction location meeting the preset effective coverage rate can be found, improving the flexibility and accuracy of site selection, and also ensuring that the construction location of the signal tower can achieve the expected coverage effect.

[0084] Further, in embodiment one, the above step S4 further comprises:

[0085] Any one of the constructible regions is taken as a second region, when the first target signal tower is installed in the constructible location of the second region, if the area with an effective coverage rate of the first target signal tower 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 a third region is selected from the constructible region to construct a second target signal tower, 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] The first target signal tower and the second target signal tower are combined, and the total effective coverage rate is retested. When the total effective coverage rate is greater than or equal to the preset effective coverage rate, the second region is taken as the construction address of the first target signal tower, and the third region is taken as the construction address of the second target signal tower.

[0087] Specifically, assuming that the coverage range of a certain signal tower is limited in the plurality of buildable areas that have been determined, the coverage effect of the single signal tower needs to be evaluated and multiple signal towers are selected for combination if necessary. The specific steps are as follows: any one of the buildable areas is taken as a second area, and a first target signal tower is installed at the buildable location in the second area, the effective coverage rate of the first target signal tower is tested, and it is checked whether the coverage area is greater than or equal to the area of the preset effective coverage rate. If the effective coverage area of the first target signal tower is less than or equal to 1 / N of the site selection range area after the first target signal tower is installed in the second area and the test finds that the effective coverage area is 1 / 5 of the site selection range area and the preset effective coverage rate is 80%, a third area is selected from the buildable area to build a second target signal tower. Assuming that N=5 and the effective coverage area of the first target signal tower is 1 / 5 of the site selection range area, the third area is selected. The first target signal tower and the second target signal tower are combined. The total effective coverage rate after the combination is tested, and it is checked whether it is greater than or equal to the preset effective coverage rate. Assuming that the total effective coverage rate after the combination of the first target signal tower and the second target signal tower is 85%, which is greater than the preset effective coverage rate 80%, if the total effective coverage rate is greater than or equal to the preset effective coverage rate, the second area is taken as the construction address of the first target signal tower, and the third area is taken as the construction address of the second target signal tower. Through the above steps, the coverage effect of the single signal tower can be evaluated, and multiple signal towers are selected for combination if necessary, so as to ensure that the signal coverage rate in the entire site selection range reaches the preset standard.

[0092] The test unit is used to test the signal reception strength of areas other than the area where the target signal tower is located within the selected site, based on the signal transmission height of the target signal tower.
