Problems solved by technology

First, if there is no scientific and effective method for identifying the central ant nest point in the case of multi-point aggregation, different conclusions will be drawn on the number of occurrence points, which will lead to deviations in the occurrence area, and thus cannot accurately support government decision-making; second, if each It is necessary to recalculate all the ant nest points in the area, and the calculation workload is huge

Embodiment 1

[0071] like Figure 1-6 As shown in the figure, a calculation method for the occurrence point of RIFA infestation area, the nouns in the method are defined as follows:

[0072] Let dist be the outer edge distance where two or more live ant nests are regarded as the same occurrence point.

[0073] Let E be the edge set of ant nest points, and the distance between the two endpoints (ant nest points) of each edge in E is less than dist.

[0074] To-be-treated point: refers to the ant nest point that has not yet been calculated and processed for the effective point of the ant situation area.

[0075] Treated site: refers to the ant nest site that has been calculated and processed for the effective point of ant situation area.

[0076] Gathering point set: When the distance between the outer edge of N actual ant nest points and 1 actual ant nest point A is less than dist, these N+1 ant nest points are calculated as 1 effective point when calculating the ant situation occurrence a...

Embodiment 2

[0188] Under the same conditions as other methods and embodiments, such as Figure 7 It shows that the newly collected ant nest points A, B, C, D and E, the outer edge distance between points A and B is less than 40 meters, the outer edge distance between points B and C is less than 40 meters, and the distance between points C and D is less than 40 meters. The outer edge distance between points D and E is less than 40 meters, and the outer edge distance between points D and E is less than 40 meters.

[0189] The calculation process of the occurrence point of the ant infection area is as follows:

[0190] When points A, B, C, D, and E are collected and uploaded to the cloud server, the attribute "Aggregate Point Number" is assigned a value of 0, "degree" is assigned a value of 0, and "less than degree points" is assigned a value of 0.

[0191] According to the algorithm step S1, put the edges AB, BC, CD, DE into the edge set.

[0192] Solve according to algorithm step S2: deg...

Abstract

The invention discloses a method for calculating a solenopsis invicta situation area occurrence point, and the method comprises the steps: 1, constructing edges of to-be-processed points and processed points, constructing edges between the to-be-processed points, and setting the state of each point in a gathering point set where the processed points having edges with the to-be-processed points are located to be to be processed; 2, setting attribute degrees and values smaller than degree points for all the to-be-processed points, 3, constructing N aggregation point sets for all the to-be-processed points based on the attribute values of the degrees and the values smaller than the degree points, N being greater than or equal to 1, and each constructed aggregation point set being an effective point for calculating the ant situation occurrence area, the central point of the constructed aggregation point set and other points have edges, the numerical value of the attribute'degree 'of the central point is the maximum, and if a plurality of points with the maximum numerical value of the attribute'degree' exist, the point with the maximum value of the attribute'less than the degree point number 'is selected as the central point; and step 4, ending the method.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a method for calculating the occurrence point of RIFA ants. Background technique [0002] RIFA is listed as one of the 100 most destructive invasive organisms in the world, which is harmful to human body, agriculture and forestry, public safety and regional ecological diversity. RIFA is a major invasive pest that seriously threatens human safety, public facilities, agricultural and forestry production and biodiversity. It is an omnivorous soil-dwelling ant and is listed as a very destructive and aggressive invasive pest internationally. one of the creatures. RIFA has the habit of tending to electromagnetic waves and dissipating heat, especially in winter when the temperature is low, RIFA likes to build nests in street lights, traffic signal light boxes, program-controlled switch boxes, etc., and eat the wire rubber, causing damage to facilities and malfunctions. It has occ...
