A fast site selection method for large-scale communication base stations considering slope and height difference

Abstract

The invention discloses a large-range communication base station rapid site selection method considering gradient and altitude difference. The method comprises the following steps: S1, preparing digital elevation model data with 30-meter resolution of a target area; s2, introducing the data into ArcMap for polymerization; s3, performing dicing operation on the aggregated data; s4, converting the sliced data blocks into the same coordinate system, taking each data processing unit as a data point, arranging the data points by adopting a bubbling sorting method according to the elevation h, and recording the elevation of the lowest point as h0 and the elevation of the highest point as h1; respectively screening out a high-point queue T1 of which the elevation value is greater than (H + h0) and a low-point queue T2 of which the elevation value is less than (h1-H); and S5, selecting two points of which the height difference is not lower than H and the horizontal distance is not longer thanL. According to the method, a target area is segmented into a plurality of data processing units, then a bubbling method is used for sorting according to the elevations of the data processing units, and finally base station addresses meeting requirements are selected; efficient and rapid screening can be carried out, and the integrity of a screening result can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of surveying and mapping, and in particular relates to a method for quickly selecting a site for a large-scale communication base station in consideration of slope and height difference. Background technique [0002] At present, taking into account the constraints of slope and height difference, the site selection of communication base stations for some long railway lines is mainly done manually or on topographic maps to select sites that meet the requirements. However, the site selection cycle is long and there will be a large number of Cases where more appropriate site points are missing. The selection of the site is mainly to consider the terrain height difference and slope factors, and the automatic site selection is mainly through the software, using the digital elevation model to calculate point by point, and select the location that meets the requirements. At present, the domestic and foreign softwar...

Problems solved by technology

At present, the domestic and foreign software for dealing with digital elevation model (DEM) analysis is mainly Arcmap, SuperMap, etc., but their analysis of elevation and slope is a single element analysis, and because of the large area of ​​long-term trunk railways, especially in Southwest my country In complex and dangerous mountainous areas and areas with large terrain fluctuations, it is impossible to quickly and efficiently screen out communication base station sites that meet the slope and height difference factors
