Description

Technical Field

[0001] The present invention relates to the technical field related to intelligent forestry prevention and control, and in particular to a method and device for planning a forest and grassland fire rescue path. Background Art

[0002] Forest and grassland fire rescue refers to the process of taking a series of measures to quickly extinguish the fire, reduce losses, and protect personnel and ecological safety after a forest and grassland fire occurs.

[0003] Forest and grassland fire rescue often requires shortest path planning based on the location of firefighting materials, resources and equipment, and rescue personnel within the range to form a rescue planning path.

[0004] The current rescue planning path is often calculated based on the shortest path planning algorithm. This method often only focuses on the shortest straight-line distance between the starting point and the fire point, and cannot comprehensively consider other path planning factors such as the internal path of the forest area. Therefore, although the planned rescue path has the shortest straight-line distance, it is less practical. Summary of the invention

[0005] The purpose of the present invention is to solve at least one of the deficiencies of the prior art and to provide a method and device for planning a forest and grassland fire rescue path.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] Specifically, a forest grassland fire rescue path planning method is proposed, including the following:

[0008] Step 110, through the location of the fire point, according to the set nearby range conditions, search for the location of firefighting materials, resource equipment, rescue personnel, and rescue trajectory routes within the range;

[0009] Step 120, forming road network vector data based on the internal path of the current forest area, and pre-selecting a starting point position in the map;

[0010] Step 130: Use the starting point as the starting point for searching, find the internal path closest to the starting point in the road network vector data and record it as the middle path, calculate the point on the middle path closest to the starting point and record it as the middle point, and record the path between the starting point and the middle point as the first road section;

[0011] Step 140, find an internal path that intersects with the middle path and whose intersection is closest to the fire point and is recorded as the current path, and intercept the path between the middle point and the intersection and record it as the second section;

[0012] Step 150, updating the intersection point to the middle point, updating the internal path that intersects with the middle path and whose intersection point is closest to the fire point to the middle path, and repeating step 140 until the internal path that intersects with the middle path and whose intersection point is closest to the fire point is the internal path closest to the fire point in the road network vector data;

[0013] Step 160: output the first road section and all the second road sections, so that the first road section and all the second road sections together form a rescue planning path.

[0014] Furthermore, the method further comprises:

[0015] When there is a weather station within the set nearby range of the fire point, the real-time environmental weather will also be displayed synchronously.

[0016] The present invention also proposes a device for planning a forest and grassland fire rescue path, comprising the following:

[0017] The first search module is used to search for the location of firefighting materials, resource equipment, rescue personnel, and rescue trajectory routes within the range according to the set nearby range conditions through the location of the fire point;

[0018] A starting point location determination module is used to form road network vector data based on the internal path of the current forest area and pre-select the starting point location in the map;

[0020] The third search module is used to find an internal path that intersects with the middle path and whose intersection is closest to the fire point, record it as the current path, and intercept the path between the middle point and the intersection, record it as the second section;

[0021] A loop execution module is used to update the intersection point to the middle point, update the internal path that intersects with the middle path and whose intersection point is closest to the fire point to the middle path, and repeatedly execute the third search module until the internal path that intersects with the middle path and whose intersection point is closest to the fire point is the internal path closest to the fire point in the road network vector data;

[0022] The path planning module is used to output the first road section and all the second road sections, so that the first road section and all the second road sections together form a rescue planning path.

[0023] The beneficial effects of the present invention are:
