Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is apparent that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
It should be understood that, in various embodiments of the present invention, the sequence number of each process does not mean that the execution sequence of each process should be determined by its functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
It should be understood that in the present invention, "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements that are expressly listed or inherent to such process, method, article, or apparatus.
The technical scheme of the invention is described in detail below by specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
With the acceleration of economic development, three-dimensional traffic and high-rise building construction of high-speed railways, viaducts, overpasses, highways and the like are increasing. In this stereoscopic scenario, the signal coverage area is no longer the ground and/or a building proximate the ground. In order to ensure that signals can cover the elevated road or the high floors of the building, the network in the stereoscopic scenario needs to be reasonably optimized by the staff. In the network optimization process, the information of the downtilt angle, azimuth angle, longitude and latitude of the antenna of the base station is key data. Especially for diversified stereoscopic scenes, determining a reasonable antenna downtilt angle is a basis for improving network quality.
There are two general ways to optimize the downtilt angle of the antenna of the base station: one is to arrange staff to survey the target building height on site, thereby realizing the on-site optimization of the base station antenna, namely the adjustment of the mechanical downtilt angle. The other is that after the on-site investigation by the staff, the on-site parameters are obtained and transmitted back to the background for analysis and calculation, and then the electronic downtilt angle adjustment is carried out by the background. At present, the two methods for optimizing the downward inclination angles of the base station antennas all require workers to go to the site to perform field investigation, consume more labor cost and time, and have low investigation efficiency.
Particularly, in the network optimization of stereoscopic scenes such as high-speed railway lines, the investigation sites are usually far away, and are located in places such as rural areas, villages and towns, mountain areas, gobi and the like. To optimally adjust a section of high-speed railway, it is often necessary for a worker to travel to and from each base station. Sometimes, the traffic is limited and even the staff is required to walk to the base station. Meanwhile, due to the complexity of the high-speed rail, such as a high-speed rail formed by bridges, a worker performs optimization of a base station, and usually needs to adjust the antenna of the base station twice or more. The existence of the situation causes that a large amount of labor cost and time are consumed in the process of surveying and adjusting by staff, and the surveying efficiency is low.
In order to solve the above problems, the inventor provides a network optimization method, a device, equipment and a storage medium, so that a worker can calculate a target building height according to a target building length and a base station length in a satellite map of a target scene. The method can lead the staff not to need to survey on site or go to the tower for many times, saves labor cost and optimizes adjustment efficiency.
At present, the method for calculating the downtilt angle of the antenna of the traditional base station is suitable for a scene that the height of the base station is larger than the target building height of the covered area. However, with the development of technology, buildings in three-dimensional scenes are continuously increased, and the height of a base station antenna is about 20 meters as a beautifying antenna, so that the traditional method for calculating the downtilt angle of the base station antenna is not suitable for all application scenes. Aiming at high-rise houses, in the prior art, the problem of network coverage is mainly solved by building a room subsystem. However, the method has the problems of long construction period, high cost, small popularization range and low utilization rate.
Aiming at the problem, the network optimization method, the device, the equipment and the storage medium provided by the inventor can optimize the network by accurately and efficiently calculating the downtilt angle of the antenna of the base station under the condition that the height of the target building is higher than that of the base station. The downtilt angle may be the angle at which the antenna is tilted up. By adjusting the downtilt angle, the network can cover a high-rise residential area, network optimization with low cost and short construction period is realized, and user experience is improved.
Fig. 1 is a schematic diagram of a base station information coverage area according to an embodiment of the present application. As shown, a base station is located near a building, taking as an example the network coverage of the building, the coverage area of the signal of the base station's antenna may include the building.
The signal coverage area of the antenna of the base station can be realized by adjusting the downward inclination angle of the antenna of the base station.
As shown in the figure, the current layer number of the building is 1 layer, and when the layer number of the building is increased to 2 layers, in order to enable the 2 layers of the building to be covered by the signal, the downward inclination angle of the antenna needs to be adjusted so as to enable the antenna to cover the 2 layers without adding a base station. Or when other buildings are expanded around the building, in order to enable the expanded building to cover the network, the downward inclination angle of the antenna needs to be adjusted to cover the other buildings without adding a base station.
Currently, the downtilt angle adjusting method mainly comprises two kinds of field adjustment and remote adjustment. The on-site adjustment requires a worker to go up the tower to adjust the mechanical downtilt angle of the antenna. The remote adjustment is to adjust the electronic downtilt angle of the antenna by staff in the background. With the development of technology, in the setting of base station antennas, antennas capable of being remotely adjusted are increasing.
In the application, the adjustment mode of the downward inclination angle of the antenna is mainly remote adjustment, and on-site adjustment is auxiliary, so that the aim of improving the adjustment efficiency is fulfilled. The execution body is used for calculating the downtilt angle in the remote adjustment process and realizing adjustment, and can be a software and/or hardware device. When the execution body is a hardware device, the execution body may be an electronic device such as a mobile phone, a tablet, a computer, a server, etc. When the execution body is software, the execution body may also be a tuning platform implemented by code. The execution body may also be an electronic device in which the code of the adjustment platform is installed.
Fig. 2 shows a flowchart of a network optimization method according to an embodiment of the present application. On the basis of the embodiment shown in fig. 1, as shown in fig. 2, with the electronic device as an execution body, the method of this embodiment may include steps S101 to S103, which are specifically as follows:
S101, acquiring base station information, wherein the base station information at least comprises base station height, mechanical downward inclination angle and electronic downward inclination angle.
In this embodiment, the base station information acquired by the electronic device may come from a storage module of the electronic device, where the base station information is prestored in the storage module of the electronic device by a staff. Alternatively, the base station information may be from other storage modules, such as a cloud storage module, a storage module of other electronic devices, and so on. The storage module is connected with the electronic equipment through a communication interface, so that data transmission of base station information is realized. The communication interface may be a physical interface or a wireless communication network interface. Alternatively, the base station information may be input to the electronic device by a worker in this step.
The base station information at least comprises a base station height, an antenna height, a mechanical downtilt angle, an electronic downtilt angle, a base station name, a base station number, a base station longitude, a base station latitude, platform information and the like.
Wherein the base station height and the antenna height are used to indicate the heights of the base station and the antenna, respectively.
The mechanical downtilt angle is the downtilt angle of the antenna which needs to be adjusted by a worker on site. The electronic downtilt is the angle of the downtilt of the antenna that can be adjusted by the background.
The base station name is used for uniquely identifying a base station, and is generally determined by the place name where the base station is located and the purpose, for example, a mountain high iron F of three sense villages in Lancoln county, a village high iron F of suburb, a north sentry high iron F of the big north in the urban area, and the like.
S102, determining the target downtilt angle of the antenna of the base station according to the satellite map of the target scene and the base station information.
In this embodiment, the target scene includes a base station, and the target building height of the network needs to be optimized within the coverage area of the base station. The electronic device can determine one or more satellite maps based on the location of the base station. The satellite map is a picture taken by the base station in a period of time in sunny weather.
The electronic device may measure the target building and base station shadows from the satellite map. The electronic device may calculate the target building height according to the base station height, the target building length, and the base station length in the known base station information. According to the parameters of the target building height, the antenna length, the lobe angle and the like, the electronic equipment can calculate and obtain the target downtilt angle of the antenna. The target downtilt is used to indicate the optimum downtilt of the antenna when the signal is covering the building.
S103, adjusting the downward inclination angle of the antenna of the base station according to the target downward inclination angle.
In this embodiment, according to the target downtilt angle calculated in S102, and the current mechanical downtilt angle and the electronic downtilt angle of the antenna, the electronic device may calculate an adjustment angle of the downtilt angle of the antenna. Further, the electronic device sends an adjustment instruction to remotely adjust the electronic downtilt angle of the antenna of the base station. Or the electronic equipment sends the adjusting angle to the staff, the staff realizes the on-site adjustment of the mechanical downtilt angle of the antenna of the base station,
according to the network optimization method, after the electronic equipment acquires the base station information, the target building height is calculated according to the base station height in the base station information, the target building shadow length in the satellite map and the base station shadow length. And the electronic equipment calculates a target downward inclination angle according to the target building height and the antenna height. And further, according to the target downward inclination angle and the mechanical downward inclination angle and the electronic downward inclination angle in the base station information, the electronic equipment calculates and obtains the adjustment angle of the antenna. According to the adjustment angle, the electronic equipment adjusts the downward inclination angle of the antenna. According to the method, the satellite map and the base station information are used for determining the height of the target building, the target downward inclination angle of the base station antenna is calculated according to the height of the target building, the process that workers need to acquire the height information of the target building through on-site investigation in the prior art is optimized, the investigation efficiency is improved, the labor cost is reduced, and the network optimization speed is improved.
Fig. 3 shows a flowchart of another network optimization method according to an embodiment of the present application. On the basis of the embodiment shown in fig. 1 and fig. 2, as shown in fig. 3, with the electronic device as an execution body, the method of this embodiment may include the following steps:
s201, acquiring base station information, wherein the base station information comprises base station height, mechanical downward inclination angle and electronic downward inclination angle.
Step S201 is similar to the implementation of step S101 in the embodiment of fig. 2, and is not described herein.
S202, determining the target building shadow and the base station shadow according to the satellite map of the target scene.
In this embodiment, the target scene includes a base station, and the target building height of the network needs to be optimized within the coverage area of the base station. The electronic device can determine one or more satellite maps based on the location of the base station. The satellite map is a picture taken by the base station in a period of time in sunny weather.
The electronic device can determine the target building and base station shadows in the satellite picture by measurement. Furthermore, according to the scale of the satellite picture and the target building shadow and the base station shadow in the satellite picture, the electronic device can calculate the target building shadow and the base station shadow in practice.
In the satellite picture, the target building shadow and the base station shadow can be measured by the existing picture processing tool in the electronic equipment.
For example, as shown in fig. 4, a base station and a target scene diagram of a high-speed rail covered by the base station are shown. Wherein the target building height is a high-speed rail. The method of measuring the shadow length of the high-speed rail is illustrated in the figure. It can be seen from fig. 4 that the shadow of the high-speed rail is located above the high-speed rail. As indicated by the straight line of measurement indicated by the shadow height in the figure, the shadow is from the junction of the high-speed rail and the shadow, along the column direction of the rail, to the height at which the shadow ends. By drawing the measurement line in the satellite map, the electronic device can acquire the shadow length of the high-speed rail by measuring the measurement line. The electronic device can directly measure the length of the measuring straight line through the existing picture processing tool. The electronic device can also obtain the endpoint coordinates of the measuring straight line through the existing picture processing tool, and calculate the length of the measuring straight line according to the endpoint coordinates.
When there is no open area in the target scene, as shown in fig. 4, the electronic device may measure the target building length in segments according to the projection of the target building height on other buildings.
S203, determining the target building height according to the base station height, the target building shadow and the shadow of the base station.
In this embodiment, the electronic device may acquire the base station height in the base station information from S201. The electronic device may obtain the measured base station and target building shadows from S202. According to the principle of similar triangle, the ratio of the shadow length to the length of two groups of objects in the sun at the same time is the same. Thus, according to the principle of similar triangles, the relationship of base station height, base station shade length, and target building height, target building shade length is as follows:
the calculation formula of the target building height can be obtained by deformation according to the formula (1):
for example, when the base station height is 35 meters, the base station shadow length is 63.45 meters and the building shadow length is 45.17 meters. At this time, the target building height is calculated to be 24.9 meters according to the formula (2).
In one example, to ensure accuracy of the calculations, multiple satellite maps at different times may be used, with multiple calculations resulting in multiple target building heights. And taking the average value of the plurality of target building heights obtained by multiple times of calculation as the target building height obtained by final calculation.
S204, determining the coverage distance of the base station according to the satellite map of the target scene.
In this embodiment, the electronic device may also determine, by measurement, a linear distance from the base station to the target building in the satellite map. The straight line distance is the coverage distance of the base station. The coverage distance of the base station is measured in the same manner as the target building shadow and the base station shadow, and can be measured by the existing picture processing tool in the electronic equipment.
The coverage distance of the base station may be measured after the target building and base station shadows are measured according to the steps shown in the embodiment. The coverage distance of the base station can be measured simultaneously with the target building and base station shadow. The coverage distance of the base station can also be measured before the target building and base station coverage measurements. In the present embodiment, the execution sequence of step S202 and step S204 is not limited by the described operation sequence.
For example, as shown in fig. 5, a schematic diagram of coverage distance measurement of a base station in a target scenario is shown. The target building in this figure is a high-speed rail track, and the base station is located above the high-speed rail track. The electronic equipment passes through the base station and draws a line segment perpendicular to the high-speed rail. The line segment is shown as the covered distance in the figure. By drawing the measurement straight line of the coverage distance in the satellite map, the electronic equipment can directly measure and obtain the length of the measurement straight line through the existing picture processing tool. The electronic device can also obtain the endpoint coordinates of the measuring straight line through the existing picture processing tool, and calculate the length of the measuring straight line according to the endpoint coordinates.
S205, determining the height difference of the target building and the antenna according to the target building height and the antenna height.
In this embodiment, the electronic device may calculate, according to the target building height calculated in S203 and the antenna height in the base station information obtained in S201, a difference between the two, where the difference is used to indicate a height difference between the target building and the antenna. The calculation formula of the height difference is as follows:
height difference = antenna height-building height (3)
The value of the height difference is the antenna height minus the building height. Since there is a case where the target building height is higher than the antenna height, the value of the height difference may be negative.
For example, when the target building height is 24.9 meters and the base station height is 29 meters, the height difference is 4.1 meters. When the building height is 33 meters and the base station height is 29 meters, the height difference is-4 meters.
In one example, when the target building height is a high-rise building, there may be situations where the base station signal only needs to cover to a certain floor of the target building. In this case, the target building height is the height of a floor that needs to be covered by the signal, not the height of the entire target building.
S206, determining the target downtilt angle of the antenna of the base station according to the height difference, the coverage distance and the vertical lobe angle.
In this embodiment, the antenna covers a signal with an angular range related to the vertical lobe angle at a downward tilt angle. Wherein the vertical lobe angle defines the beam width of the antenna vertical plane. The smaller the vertical lobe angle, the faster the signal decays away from the main beam direction.
Therefore, after the coverage distance of the antenna is obtained in S204 and the height difference is obtained in S205, the target downtilt angle of the antenna can be calculated according to the inverse trigonometric function and the vertical lobe angle, and the calculation formula is specifically as follows:
for example, when the vertical lobe angle is 7 degrees, the relationship between the downtilt angle of the antenna and the height and coverage distance of the target building height can be calculated by the formula (4). The specific relationship thereof can be shown in table 1. Wherein, the units of the base station height, the track height, the height difference, the coverage distance 1, the coverage distance 2 and the coverage distance 3 are meters. Wherein, the unit of the downward inclination angle 1, the downward inclination angle 2 and the downward inclination angle 3 is degree.
TABLE 1
For example, an example of a base station above a target building height is shown in fig. 6. Wherein, the actual coverage height is shown by a dotted line in the figure, and is used for indicating the level height of the signal to be covered. The actual coverage height is parallel to the ground. The difference in height between the antenna and the target building height is shown. Assuming that the height difference is 5 meters, the distance between the antenna and the target building height is 400. At this time, as can be seen from the above table 1, when the vertical lobe angle is 7 degrees, the target downtilt angle of the antenna is 4.22 degrees.
For example, when the building is higher than the base station in height, as shown in fig. 7, the actual coverage height is a floor of the target building, and is shown by a broken line in the figure. Wherein the difference between the actual coverage height and the antenna height is shown as the difference in height in the figure. At this time, the height difference is a negative number. Assuming that the height difference is-5 meters, the distance between the antenna and the target building height is 400. At this time, as can be obtained by calculation of the above formula (4), the target downtilt angle of the antenna is 2.78 degrees when the vertical lobe angle is 7 degrees. Compared with a room subsystem in the prior art, the downward inclination angle adjustment of the antenna realizes network optimization with low cost and short working period in high-rise buildings, and improves user experience.
S207, determining the adjustment angle of the downtilt angle of the antenna of the base station according to the target downtilt angle, the mechanical downtilt angle and the electronic downtilt angle.
In this embodiment, the electronic device calculates the target downtilt angle of the antenna according to S206, where the target downtilt angle is used to indicate the optimal downtilt angle that can be adjusted when the target building height needs to be covered. The electronic device may obtain a mechanical downtilt angle and an electronic downtilt angle in the base station information according to S201, where the mechanical downtilt angle and the electronic downtilt angle are used to indicate a downtilt angle of the current antenna.
According to the target downtilt angle, the mechanical downtilt angle and the electronic downtilt angle, the electronic equipment can judge whether the downtilt angle of the antenna is the optimal setting. If the downtilt of the current antenna is optimally set, no adjustment of the downtilt is required.
Otherwise, the electronic equipment calculates the adjustment angle of the downtilt according to the target downtilt and the mechanical downtilt of the antenna and the electronic downtilt. The calculation formula of the adjustment angle of the downtilt angle is as follows:
adjustment angle = mechanical downtilt + electronic downtilt-target downtilt (5)
For example, when the target downtilt angle is calculated to be 3.96 degrees, since the minimum unit of angular adjustment of the downtilt angle is 1 degree, the target downtilt angle may be obtained to be 4 degrees. Assuming that the mechanical downtilt angle and the electronic downtilt angle of the antenna of the base station are 4 degrees and 3 degrees, respectively, the downtilt angle of the antenna of the base station can be calculated to be 7 degrees. According to the formula (5), the adjustment angle of the downtilt angle of the antenna of the base station can be calculated to be 3 degrees.
S208, determining an adjustment method of the downtilt angle of the antenna of the base station, wherein the adjustment method comprises on-site adjustment or remote adjustment.
In this embodiment, the adjustment mode of the downtilt angle of the antenna is mainly remote adjustment, and on-site adjustment is auxiliary. Therefore, after the adjustment angle is calculated according to S207, the electronic device compares the adjustment angle with the electronic downtilt angle according to the adjustment angle. If the antenna of the base station can be adjusted to an optimal state by remotely adjusting the electronic downtilt angle, determining that the downtilt angle adjusting method of the antenna of the base station is remote adjustment.
For example, when the mechanical downtilt angle and the electronic downtilt angle are respectively 4 degrees and 3 degrees, and the adjustment angle is 2 degrees, the downtilt angle of the antenna can be adjusted to be optimal by adjusting the electronic downtilt angle. At this time, the downtilt adjustment method of the antenna of the base station is determined to be remote adjustment.
Otherwise, the electronic equipment further analyzes the adjustment method of the downtilt angle of the antenna, and divides the adjustment angle into two parts, namely on-site adjustment and remote adjustment. For example, when the mechanical downtilt angle and the electronic downtilt angle are respectively 4 degrees and 3 degrees, and the adjustment angle is 5 degrees, the downtilt angle of the antenna cannot be adjusted to be optimal only by the adjustment of the electronic downtilt angle. Thus, the electronic device determines the angle of remote adjustment to be 3 degrees and the angle of on-site adjustment to be 2 degrees.
S209, adjusting the downward inclination angle of the antenna of the base station according to the adjustment angle.
In this embodiment, the electronic device adjusts and optimizes the antenna of the base station according to the downtilt adjustment method of the antenna determined in S208. When the electronic equipment needs to remotely adjust the antenna of the base station, the electronic equipment sends an adjustment instruction to the antenna of the base station through the background of the base station according to the determined adjustment angle. The adjusting instruction is used for indicating the antenna of the base station to adjust a certain angle so as to adjust the downward inclination angle of the antenna to be optimal. When the electronic equipment needs to perform on-site adjustment on the antenna of the base station, the electronic equipment sends information to staff according to the on-site adjustment angle. This information is used to instruct the staff to go to the base station and adjust the antenna of the base station in the field.
According to the network optimization method, after the electronic equipment acquires the base station information, the target building height is calculated according to the base station height in the base station information, the target building shadow length in the satellite map and the base station shadow length. And the electronic equipment calculates a target downward inclination angle according to the target building height and the antenna height. And the electronic equipment calculates the adjustment angle of the antenna according to the target downward inclination angle, the mechanical downward inclination angle and the electronic downward inclination angle in the base station information. And the electronic equipment determines an adjustment scheme of the downtilt angle of the antenna of the base station according to the adjustment angle, and the mechanical downtilt angle and the electronic downtilt angle in the base station information. Furthermore, according to the adjustment scheme, the electronic device adjusts the downtilt angle of the antenna of the base station. According to the method, the satellite map and the base station information are used for determining the height of the target building, the target downward inclination angle of the base station antenna and the adjustment angle of the antenna are calculated according to the height of the target building, the method that workers need to survey on site in the prior art to acquire the height information of the base station and the target building is optimized, the survey efficiency is improved, the labor cost is reduced, and the network optimization speed is improved.
