Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The embodiment of the invention provides a base station selection method, which can select a certain number of new base stations from a plurality of new base stations for monitoring. As shown in fig. 1, the base station selection method includes the following steps:
s1, receiving base station related parameters of a plurality of base stations.
The multiple base stations may be a batch of new base stations, or multiple batches of new base stations, and the number of the multiple base stations may be any number, for example, several, tens of or hundreds of new base stations. In addition, the plurality of base stations may further include other base stations besides the newly created base station, which is not specifically limited in this application. The newly-built base station may be a newly-built base station, and the other base stations may be base stations with changed parameters in the already-built base stations, for example, base stations hanging new frequency wires, which may affect the lives of residents around the newly-built base stations.
Illustratively, the base station related parameters may include parameters such as base station transmission power P, base station name, base station address, base station GPS data, and the like.
S2, dividing the base stations into a plurality of base station groups according to the base station related parameters.
Illustratively, the base stations are divided into a plurality of base station groups according to the size of the base station transmitting power P.
And S3, extracting a preset number of base stations from the plurality of base station groups respectively according to a plurality of preset proportions to be used as the base stations to be monitored.
The predetermined ratio can be any ratio of 0-100%, for example, 0%, 10%, 30%, 50%, 70% and 100%. Extracting base stations from a plurality of base station groups at a plurality of predetermined ratios, respectively, means that base stations can be extracted at different ratios from the plurality of base station groups. The predetermined number is a total number of base stations extracted from the plurality of base station groups. Illustratively, the plurality of base stations are divided into three base station groups, a first number of base stations are extracted from a first base station group at a ratio of 100%, a second number of base stations are extracted from a second base station group at a ratio of 50%, and base stations are extracted from a third base station group at a ratio of 0%, and the extracted first number plus the second number of base stations are a preset number of base stations, namely base stations to be monitored.
In the above-described embodiments of the present application, by receiving base station related parameters of a plurality of base stations and dividing the plurality of base stations into a plurality of base station groups according to the base station related parameters, base stations having different parameter characteristics (e.g., different transmission powers) may be divided into different base station groups; and then extracting base stations from the plurality of base station groups at a plurality of preset ratios, so that the base stations can be extracted from the base station groups with different parameter characteristics at different probabilities. In this case, the required base stations can be preferentially extracted for monitoring, so that the monitoring efficiency can be improved.
Example two
In this embodiment of the invention, the base station related parameters comprise at least one of a base station transmission power P, a horizontal distance s of the monitoring point from the base station, and a height difference h of the monitoring point from the base station. The monitoring point is the position which can be reached by the public in the electromagnetic sensitive point and is closest to the base station antenna, and when the transmitting antenna of the mobile communication base station is a directional antenna, the monitoring point is arranged in the main lobe direction of the antenna in principle. The electromagnetic sensitive points comprise hospitals, nursing homes, kindergartens, primary and secondary schools, residential houses and the like around a base station. The horizontal distance between the monitoring point and the base station refers to the linear distance between the antenna of the base station and the projection of the monitoring point on the horizontal plane; the height difference between the monitoring point and the base station refers to the difference between the heights of the base station antenna and the monitoring point in the vertical direction.
At this time, as shown in fig. 2, the step S2 of dividing the plurality of base stations into a plurality of base station groups according to the base station related parameters may include the following steps S21 and S22:
and S21, evaluating the electromagnetic radiation overproof risks of the base stations according to at least one of the transmitting power P, the horizontal distance S between the monitoring point and the base station and the height difference h between the monitoring point and the base station.
Wherein based on two parameters of s and h, r is calculated according to the formula2＝s2+h2The linear distance r between the monitoring point and the base station can be obtained. While the electromagnetic radiation power density P of the monitoring pointdRelating to the base station transmission power P and the linear distance r of the monitoring point from the base station, i.e. Pd∝P/(4πr2) I.e. Pd∝P/[4π(s2+h2)]. Since the greater the power density of the electromagnetic radiation, the higher the risk of electromagnetic radiation overproof, the relative high or low of the risk of electromagnetic radiation overproof for multiple base stations can be evaluated based on one or more of these three parameters P, s and h. Moreover, according to the relational expression, the greater the P is, the higher the risk of exceeding the standard of the electromagnetic radiation is; the smaller s is, the higher the overproof risk of electromagnetic radiation is; the smaller h, the higher the risk of overproof electromagnetic radiation. And, since P is a first power and s and h are second powers in the relation, P isdWill be more sensitive to changes in s and h, and normally the horizontal distance s of the monitoring point from the base station will be much greater than the height difference h between the monitoring point and the base station, so that between s and h, the change in s will be to PdThe effect of (c) is greater. In summary, the above-mentioned 3 base station parameters have s, h, and P impact on the electromagnetic radiation overproof risk.
In the application process, at least one of the three parameters can be used to evaluate the relative level of the overproof electromagnetic radiation risks of the base stations according to the actual situation. Of course, the results of an evaluation using all three parameters will be more accurate than the results of an evaluation using one or two of the parameters. Further, in order to make the evaluation result more accurate, other secondary parameters influencing the exceeding risk of electromagnetic radiation can be introduced, such as the azimuth angle of the monitoring point relative to the position of the electric wire, the included angle between the monitoring point and the vertical direction of the antenna panel, the gain of the base station antenna, the feeder loss of the base station antenna and the like.
In addition, in practical application, the height difference h between the monitoring point and the base station may be a difference between the heights of the base station antenna and the monitoring point from the ground, or may be a difference between the heights of the base station antenna and the monitoring point from the ground, which may be measured directly, or may be measured by subtracting the heights (relative heights or altitudes from the ground) of the base station and the monitoring point from each other to obtain h. In addition, under the condition that the linear distance r between the monitoring point and the base station is easier to obtain relative to the horizontal distance s between the monitoring point and the base station and the height difference h between the monitoring point and the base station, the r can be directly obtained and the magnitude of the r is adopted to evaluate the overproof risk of the electromagnetic radiation, and the s and the h do not need to be obtained respectively.
And S22, dividing the base stations into a plurality of base station groups according to the exceeding risk of the electromagnetic radiation of the base stations.
In the embodiment of the invention, the electromagnetic radiation overproof risk of the base station is evaluated according to the transmitting power P, the horizontal distance s between the monitoring point and the base station and the height difference h between the monitoring point and the base station, so that a plurality of base stations can be accurately divided into different groups according to the electromagnetic radiation overproof risk, the required base stations can be extracted for monitoring according to the electromagnetic radiation overproof risk, and the monitoring efficiency is further improved.
EXAMPLE III
As shown in fig. 3, the step S22 is to divide the multiple base stations into multiple base station groups according to the risk of exceeding the electromagnetic radiation standard of the multiple base stations, and can be specifically implemented by the step S221, on the basis of which the step S3 is to extract a preset number of base stations from the multiple base station groups respectively in multiple preset ratios as the base stations to be monitored, and can be specifically implemented by the step S31, and other steps in this embodiment can be referred to the related steps, and will not be repeated here.
S221, dividing the base stations into a first base station group to an Nth base station group according to the descending order of the evaluated electromagnetic radiation overproof risks, wherein N is a positive integer greater than 1.
Exemplarily, as shown in fig. 4, in the case of evaluating the base station electromagnetic radiation overproof risk according to the transmission power P, the horizontal distance s between the monitoring point and the base station, and the height difference h between the monitoring point and the base station, the base stations may be divided into a first base station group to an nth base station group according to the magnitude order s, h, P of the influence of the three parameters on the base station electromagnetic radiation overproof risk, and the process is as follows:
s4100, dividing a plurality of base stations into n according to the sequence of S from small to large1A group of base stations;
s4200, according to the sequence of h from small to large, mixing the n1The base stations in each group of base station groups are divided into n2A plurality of base station groups, thereby dividing the plurality of base stations into n in total1*n2Group (d);
s4300, according to the sequence of P from big to small, the n is added1*n2The base stations in each group of base station groups are divided into n3A plurality of base station groups, thereby dividing a plurality of base stations into N-N1*n2*n3Group of which n1、n2、n3Are all natural numbers of 2 or more. According to the analysis, the larger the P is, the higher the overproof risk of the electromagnetic radiation is; the smaller s is, the higher the overproof risk of electromagnetic radiation is; the smaller h, the higher the risk of electromagnetic radiation overproof, and thus can be set from group 1 to group N, with the overall risk of electromagnetic radiation overproof diminishing.
It should be noted that in practical applications, in order to make the grouping finer, other secondary parameters that affect the risk of exceeding the electromagnetic radiation level, such as the phase of the monitoring point, may also be introducedFor the azimuth angle of the wire position, the included angle between the monitoring point and the antenna panel in the vertical direction, the base station antenna gain, the base station antenna feeder loss, and the like, the refining and grouping are continued after S4300, which is not described herein again, and refer to the above steps specifically. In other embodiments, if the packet cannot be, or need not be, as fine as above, n1、n2、n3One or both of which may be equal to 1, i.e. one or both grouping steps are omitted, and only two or one layer grouping is done with 2 or 1 of s, h, P parameters.
Illustratively, the base station electromagnetic radiation overproof risk can be evaluated according to the transmission power P, the horizontal distance s between the monitoring point and the base station and the height difference h between the monitoring point and the base station, and the base stations can be divided into a first base station group to an Nth base station group according to the descending order of the evaluated electromagnetic radiation overproof risks by the following methods:
s4100', dividing the horizontal distance S between the monitoring point and the base station, the height difference h between the monitoring point and the base station, and the transmitting power P into n according to the value ranges of the monitoring point and the base station1、n2、n3A number of value range segments.
For example: the horizontal distance s between the monitoring point and the base station is divided into 3 sections less than 15 meters, 15 meters to 30 meters and more than 30 meters; the height difference h between the monitoring point and the base station is divided into 3 sections less than 10 meters, 10 meters to 20 meters and more than 20 meters; the transmitting power P of the base station is divided into three sections of more than 40W, 20W-40W and less than 20W.
S4200', mixing n1、n2And n3Several value range segments are arranged and combined to form N ═ N1*n2*n3Grouping parameters, each grouping parameter comprising a specific value range of s, a specific value range of h and a specific value range of P.
Continuing with the example in step S4100': arranging and combining 3 s numerical range segments, 3 h numerical range segments and 3 three P numerical range segments into 3 × 3 — 27 grouping parameters; for example, s is less than 15 m, h is less than 10 m, and P is greater than 40W, s is less than 15 m, h is less than 10 m, 20W is less than or equal to P is less than or equal to 40W … … s is greater than 30 m, h is greater than 20 m, and P is less than 20W.
S4300', arranging the N grouping parameters into first to Nth grouping parameters according to the descending order of the predicted risk of the overproof total electromagnetic radiation.
Continuing with the example in the above step: s < 15 m and h < 10 m with P > 40W being a 1 st grouping parameter, s < 15 m and h < 10 m with 20W ≦ P ≦ 40W being a 2 nd grouping parameter … … s > 30 m with h > 20 m and P < 20W being a 27 th grouping parameter. This is because, as can be seen from the previous discussion of the present application: the electromagnetic radiation overproof risk is negatively related to s and h and positively related to P, and is relatively most sensitive to the numerical change of s and relatively least sensitive to the numerical change of P.
S4400', respectively comparing the base station parameters S, h, and P of each of the plurality of base stations with the first to nth base station parameters, thereby grouping each of the plurality of base stations into first to nth base station groups.
Continuing with the above example: the horizontal distance s between a monitoring point of a certain base station and the base station is 12 meters, the height difference h between the monitoring point and the base station is 9 meters, the transmitting power P is 25W, and after being compared with a plurality of grouping parameters, the values of s, h and P of the base station are respectively found to fall into the range of the grouping parameter 2, so that the base station is classified into the grouping parameter 2.
It should be noted that, although two methods are listed above for evaluating the electromagnetic radiation overproof risk of the base station according to the transmission power P, the horizontal distance s between the monitoring point and the base station, and the height difference h between the monitoring point and the base station, and dividing the base stations into the first base station group to the nth base station group according to the descending order of the evaluated electromagnetic radiation overproof risks, it should be understood that other methods can be adopted by those skilled in the art to implement this step.
And S31, extracting base stations from the first base station group to the Nth base station group as base stations to be monitored according to the first preset proportion to the Nth preset proportion, wherein the total number of the extracted base stations to be monitored is equal to the preset number required to be extracted.
In the embodiment of the invention, the base stations are grouped according to the descending order of the evaluated electromagnetic radiation overproof risks, and then different preset proportions can be determined in a plurality of base station groups according to the sequence of the overall electromagnetic radiation overproof risks to extract the base stations, so that the base stations are extracted to the required base stations more efficiently and accurately according to the sequence of the electromagnetic radiation overproof risks, and the monitoring efficiency is further improved.
Example four
As shown in fig. 5, the step S31 can be specifically realized by the following step S311:
s311, base stations are extracted from the first base station group to the Nth base station group as base stations to be monitored according to the first preset proportion to the Nth preset proportion which are sequentially decreased in a descending mode.
Illustratively, the extraction … … is performed at a preset rate of 100% in the first group of base stations and at a preset rate of 0% in the second group of base stations at a preset rate of 70%.
By the arrangement, the extraction proportion of the group with high overproof risk of the total electromagnetic radiation arranged in the front is high, and the base station with high overproof risk of the electromagnetic radiation can be accurately extracted for monitoring.
Alternatively, as shown in fig. 6, in the step S31, the base stations are extracted from the first base station group to the nth base station group as the base stations to be monitored at the first preset ratio to the nth preset ratio, and the total number of the extracted base stations to be monitored is equal to the preset number required to be extracted, which can also be implemented by the following steps S312 and S313:
s312, extracting base stations from the first base station group to the Mth base station group as base stations to be monitored according to a first preset proportion to an Mth preset proportion which are equal in proportion, wherein M is a positive integer less than or equal to N;
illustratively, the first to mth preset ratios are all 1.
By the arrangement, all base stations in a plurality of groups with the highest electromagnetic radiation overproof risk in the previous sequence are extracted, so that the possibility that the base stations with the highest electromagnetic radiation overproof risk are not extracted is greatly reduced. Therefore, the base station with high electromagnetic radiation standard exceeding risk can be more effectively selected for monitoring, and the monitoring efficiency is further improved.
S313, extracting base stations from the M +1 th base station group to the Nth base station group as base stations to be monitored according to the M +1 th to the Nth preset ratios different from the first preset ratio.
For example, in the M +1 th to nth preset ratios, the M +1 th preset ratio may be equal to 0 or not equal to 0 except for the M +1 th preset ratio.
The first preset proportion to the Mth preset proportion are all 1, and the M +1 th preset proportion to the Nth preset proportion are all equal to 0 except the M +1 th preset proportion, so that the preset proportions of the base station groups arranged before the M +1 th group are all 1, and the preset proportions of the base station groups arranged after the M +1 th group are all 0. The base station group monitoring method and the base station group monitoring system can ensure that only after all base stations arranged in all base station groups with higher electromagnetic radiation exceeding risk are extracted, the base stations arranged behind the base station groups with lower electromagnetic radiation exceeding risk can be extracted, so that the base stations with high electromagnetic radiation exceeding risk can be more effectively selected for monitoring, and the monitoring efficiency is further improved.
The first to mth preset ratios are all 1, and the M +1 th to nth preset ratios are all equal to 0 except for the M +1 th preset ratio, which can be expressed by the following formula F:
if x is less than or equal to y1Then x base stations are randomly extracted from the 1 st base station group so that x equals x1；
If x > y1Then, the following conditions are satisfied: x is the number ofM+1When not equal to 0, xM＝yMAnd x isM+1＜yM+1When xM+2＝0；
Wherein x represents a predetermined number, y1、y2……yM……yNRepresenting the number of base stations in each of N base station groups, by x1、x2……xM……xNIndicating the number of base stations extracted from the first through nth base station groups, i being 1,2, … … M … … N, obviously xi≤yiThe total number of the plurality of base stations is equal to Σ yiThe preset number x ═ Σ xi。
For example, to obtain an extraction result satisfying the above formula F, as shown in fig. 7, the following extraction manner may be adopted:
s7100, taking the preset number x as the current number to be extracted and the first base station group as the current base station group to start the extraction step, and executing S7200.
S7200, comparing the current quantity to be extracted with the quantity of base stations in the current base station group, and executing S7210 if the current quantity to be extracted is less than the quantity of base stations in the current base station group; if the current number to be extracted is larger than the number of base stations in the current base station group, S7220 is executed.
S7210, randomly extracting base stations with the current quantity to be extracted from the current base station group; the extraction process is ended.
S7220, extracting all base stations in the current base station group, and then performing S7221.
S7221, after the step of S7220, taking the residual quantity to be extracted as a new current quantity to be extracted, taking the next base station group as the current base station group, and continuing to execute S7200.
