Embodiment Construction

[0024] The real-time measurement method of the forest fire scene is different from the existing method, and has been greatly improved, specifically:

[0025] The ground patrol consists of 3-5 people, equipped with 2 electronic theodolites and 2 GPS receivers. The GPS receivers can realize fast positioning, and the electronic theodolites are mainly used to measure angles.

[0026] When a forest fire is found, it can realize the rapid and ready positioning of the fire point of the forest fire: such as figure 1 As shown, first use the GPS receiver to locate the two points A and B, and measure the coordinates (X A , Y A ) and (X B , Y B ), then set up the electronic theodolite at two points A and B, and measure the horizontal angles α and β; by the formula X P = X A ctgβ ...

Abstract

The invention relates to a kind of monitoring method of forest fire. It is a real-time measure method of forest fire field and adopts many advanced measure devices including the GPS receiver, the electronic theodolite and so on. It uses the GPS receiver and the electronic theodolite to measure angle to realize the in-time and exact measure of the fire point location, the fire speed and the fire height of the forest fire and report the fire behaviour of the forest fire. It supplies the first-hand information about the fire field for the directing and saving of the forest fire and supplies exact and reliable reference for the quick dispatching of the fire fighter, the collocation of the quantity of fire fighters and vehicles and the choice of the marching route. The measure method is simple and fast and the result is reliable.

Description

1. Technical field [0001] The invention relates to a forest fire monitoring method, in particular to a real-time measurement method of forest fire fire scene. 2. Technical Background [0002] Forest fire is an extremely complicated natural phenomenon. Once a forest fire occurs, how to quickly determine the location of the fire scene, understand the fire situation and fire situation in time, and determine the fire suppression plan have become the most important issues. On-site measurement has always been a difficult problem to solve. The current forest fire monitoring methods are increasingly advanced, and various methods such as satellite remote sensing, aerial monitoring, and watchtowers are applied to forest fire monitoring. However, all of the above methods have their disadvantages: [0003] ①Due to the problem of transit time and image interpretation in satellite remote sensing, it is difficult to realize fast and accurate monitoring of forest fires in practice; [00...
