Fire point positioning method of forest fireproof mobile intelligent terminal

Abstract

The invention discloses a fire point positioning method of a forest fireproof mobile intelligent terminal. The method comprises the steps that a forest ranger starts intelligent terminal software after discovering a fire; a GPS module is automatically started to obtain latitude and longitude information; the intelligent terminal is horizontally placed, and a compass calculates a horizontal angle; an intelligent terminal gravity accelerator calculates gradient information, and included angles respectively when the intelligent terminal is perpendicular to the ground and when the intelligent terminal right faces a fire point are calculated in a transformation manner, and the included angles are respectively a depressing angle and an elevation angle; fire images are shot and uploaded to a geographical information platform; and combined with DEM elevation of a GIS, the platform calculates and marks the current fire point position according to the latitude and longitude, the horizontal angle and the vertical angle. The forest ranger wears the forest fireproof mobile intelligent terminal, and when the forest ranger patrols in a moving manner, observation without dead angles and fire omission can be realized; the identification is more efficient and accurate; in addition, the method is used based on a hand-held intelligent terminal, the cost is low, and the usage is convenient.

Description

technical field [0001] The invention relates to forest fire prevention technology, in particular to a method for locating fire points of a forest fire prevention mobile intelligent terminal. Background technique [0002] Forest fire is the most dangerous enemy of the forest, and it is also the most terrible disaster of forestry, which will bring devastating consequences to the forest. Forest fires occur from time to time. When the frontline forest rangers report the fire situation, they cannot manually identify and describe the location of the fire point and pass the accurate information to the fire prevention management department. One is that the main reason is that the terrain in the mountains is complex, and the forest rangers cannot directly reach the fire point; the other is that the fire is uncontrollable, and personal safety reasons are not allowed to get too close to the fire. [0003] At present, my country's forest fire prevention situation is severe and the task...

Problems solved by technology

[0006] 2. The coverage area is not wide: the monitoring equipment is basically set up at the highest point in the forest area, and the mountainous area is characterized by ravines and mountains, so it is impossible to observe the situation on the back of the next ridge; moreover, the foot of the mountain cannot be observed on the mountain with a large angle

[0007] 3. The point cannot be moved: the monitoring equipment point is installed and cannot be moved; it cannot meet the overall needs of the forest area

[0008] 4. The cost is too high: the direct overall cost of ordinary forest fire monitoring equipment is about 200,000-800,000 per point; the forestry system cannot be built in large quantities
