Detailed Description
The invention is further described with reference to the following figures and detailed description.
In the embodiments shown in fig. 1 and fig. 2, a method for selecting an optimal combination from available candidate points of a base station includes the following steps: (1) establishing a two-dimensional coordinate system: selecting all available base station candidate points in the target area according to the actual environment and the geographic position of the target area, and sequentially numbering all available base station candidate points in a two-dimensional coordinate graph according to parameter information of the available base station candidate points to obtain the two-dimensional coordinate graph; (2) and (4) overall judgment: if the actual coverage range of all the base station candidate points in the target area is equal to the theoretical maximum coverage range of all the base station candidate points, all the base station candidate points are used as base station placement points; (3) primary screening: if a certain base station candidate point is removed and the actual coverage area of the target area is not influenced, the base station candidate point is cancelled; (4) and (4) screening again: and if the base station distance between the two base station candidate points is less than 1.5 times of the coverage radius of the base station candidate points, canceling one of the two base station candidate points which has a large overlapping degree with the coverage areas of the other base station candidate points. Through the steps, the coverage area maximization of the base station is guaranteed on the whole on the basis of guaranteeing that the existing available base station candidate points are fully utilized, and the coverage area maximization is realized by the smallest existing base station candidate points.
In the step (1), the parameter information of the candidate point of the base station includes geographical location information of the candidate point of the base station and a coverage radius of the base station. The geographical position information of the candidate points of the base stations is an unchangeable reality factor, and the accurate geographical position information determines the accurate inter-station distance between the base stations; for installation and cost savings, the specific equipment of the base station is generally the same, and the base station coverage radius is the same regardless of the severe effects of external factors.
In the step (1), in a two-dimensional coordinate graph established according to parameter information of candidate base stations, a target area is set in a first quadrant of the two-dimensional coordinate graph, and the distance between two candidate base station points represents the inter-station distance between the two candidate base station points; the numbering method for the candidate points of the base station is as follows: in the two-dimensional coordinate graph, the candidate points of the base station are numbered sequentially from left to right and from bottom to top from the lower left corner to the upper right corner in the two-dimensional coordinate graph.
The steps (2) and (3) are realized by the following method, in the two-dimensional coordinate graph, drawing a circle by taking each candidate point of the base station as the center of the circle and the coverage radius of the candidate point of the base station as the radius; if the circles corresponding to the candidate points of the base stations are not overlapped, all the candidate points of the base stations are used as the arrangement points of the base stations, and if the circle corresponding to one candidate point of the base station is removed and the coverage range of the circle corresponding to the candidate point of the base station is not influenced, the candidate point of the base station is cancelled.
In step (4), the method for determining whether the inter-station distance between two candidate points of the base station is smaller than 1.5 times of the coverage radius of the candidate points of the base station is as follows: in the two-dimensional coordinate graph, two base station candidate points are taken as circle centers, and 0.75 time of the coverage radius of each base station candidate point is taken as a radius to draw a circle, if the circles corresponding to the two base station candidate points coincide with each other, the base station distance of the two base station candidate points is smaller than 1.5 times of the coverage radius of the two base station candidate points. In the two-dimensional coordinate graph, because the distance between two candidate points of the base station represents the station distance between the two candidate points of the base station, if the station distance between the candidate point of the base station with the number of 2 and the candidate point of the base station with the number of 1 can be judged to be larger than the base station coverage radius of 1.5 times, the station distance between the candidate point of the base station with the number of 2 and the candidate point of the base station with the number of 1 is inevitably larger than the base station coverage radius of 1.5 times, so that the step (4) is completed relatively simply while all the candidate points of the base station are traversed according to the number sequence; firstly, judging whether the station spacing between the base station candidate point with the label of 1 and the base station candidate point with the label of 2 is smaller than 1.5 times of the coverage radius, if not, the base station candidate point with the label of 1 is a constructable base station; if so, judging whether the coincidence degree of the circle corresponding to the base station candidate point with the label 1 and the circles corresponding to other base station candidate points is greater than the coincidence degree of the circle corresponding to the base station candidate point with the label 2 and the circles corresponding to other base station candidate points in the coverage area graph, if so, canceling the base station candidate point with the label 1, then judging the labels to be 2 and 3, if not, canceling the label to be 2, and then judging the labels to be 1 and 3; and continuing until all base station candidate points are judged.
