Embodiment 1

[0051] The automatic weather station coverage optimization method in the present embodiment comprises the following steps:

[0052] Step 1. Modeling: randomly deploy N automatic weather stations in a two-dimensional rectangular plane T of size L*W, and mark the N automatic weather stations as: s 1 ,s 2 ,...s i ,...s N ;

[0053] Among them, s 1 is the label of the first automatic weather station, s 1 in T at position c 1 ;s 2 is the label of the second automatic weather station, s 2 in T at position c 2 ;s i is the label of the i-th automatic weather station, s i in T at position c i ; i=1, 2, . . . N; s N is the label of the Nth automatic weather station, s N in T at position c N ;

[0054] Step 2, construct the Voronoi diagram of each automatic weather station, obtain the Voronoi region of each automatic weather station;

[0055] Among them, there are two methods for calculating the Voronoi diagram of each automatic weather station in step 2:

[0056] (1), t...

Embodiment 2

[0086] Different from Embodiment 1, the specific steps in step 3 in this embodiment are:

[0087] Step 3-a, calculate the centroid corresponding to the Voronoi area of ​​each automatic weather station And update the centroid corresponding to the Voronoi region of each automatic weather station to the current position of each automatic weather station;

[0088] The centroids corresponding to the Voronoi regions of each of the above automatic weather stations are calculated using existing algorithms;

[0089] in, For the first automatic weather station s 1 The centroid corresponding to the Voronoi region of ; For the second automatic weather station s 2 The centroid corresponding to the Voronoi region of ; is the Nth automatic weather station s N The centroid corresponding to the Voronoi region of ;

[0090] Step 3-b, judgment If yes, go to step 3-c; if not, go to step 3-f;

[0091] Among them, ε is the preset threshold;

[0092] Step 3-c, in the same way as in ste...

Abstract

The present invention relates to a method for optimizing the coverage of automatic weather stations, comprising the following steps: Step 1, modeling: randomly deploying N automatic weather stations in a two-dimensional rectangular plane T whose size is L*W; Step 2, constructing each The Voronoi map of each automatic weather station obtains the Voronoi region of each automatic weather station; step 3, according to the Voronoi region of each automatic weather station, the current position of each automatic weather station is updated until each automatic weather station is obtained final location. The present invention has the advantages of: converting the automatic weather station coverage optimization problem into the optimization problem that each automatic weather station covers the corresponding Voronoi polygon area, reducing the complexity and computational complexity of the problem, not only making the node deployment and area of ​​the automatic weather station The division is more reasonable, and at the same time makes the automatic weather station coverage better.

Description

technical field [0001] The invention relates to an optimization method, in particular to an automatic weather station coverage optimization method. Background technique [0002] With the rapid development of economy and society, meteorological monitoring technology provides guarantee for the safe operation of many industries, and plays an extremely important role in disaster prevention and mitigation, traffic dispatching, agricultural production and so on. Among them, surface meteorological observation is an important basis of meteorological monitoring technology. It mainly observes and measures meteorological elements in the near-surface range. The most common is to establish an automatic weather station in a selected observation field to monitor the surrounding environment elements are collected and processed. A scientifically based automatic weather station network system can ensure the accuracy and representativeness of surface meteorological observation data. Generall...
