Embodiment Construction

[0015] The forest fire fire point location method is different from the existing methods, and has been greatly improved, specifically: the method for forest fire fire point location measurement is as follows: set up instruments at observation points A and B, and its coordinates (X A , Y A ) and (X B , Y B ) is measured by the built-in GPS module; make A, B and fire point P form a single triangle PAB; measure the magnetic azimuth A of AP, the magnetic azimuth A1 of AB, and the magnetic azimuth B of BP through the built-in electronic compass , the magnetic azimuth angle B1 of BA, and the included angle α=|A-A1| between AP and AB, the included angle β=|B-B1| between BP and BA; through GPRS (X A , Y A ), (X B , Y B ), α, β four data are sent to the server, using the digital model ① Find the coordinates of fire point P (X P , Y P ).

Abstract

The invention discloses a positioning system of a fire point of a forest fire and a using method thereof. An electronic compass is used to measure angles; a GPS is used to collect positioning data; a PDA is used to carry out data storage; a GPRS is used to transmit the data to a server; and a model is used to carry out calculation to realize positioning of a fire point of a forest fire. According to the invention, unavoidable problems existing in a current forest fire point positioning process can be solved; positioning efficiency and precision can be improved; and real-time transmission of a fire point position can be realized.

Description

1. Technical field [0001] The invention relates to a fire point location system for forest fires, in particular to a method for using the fire point location system. 2. Technical Background [0002] So far, when plotting forest fire information, pencils and erasers are mainly used to draw on paper maps. However, in the actual field operation process, the above methods all have their shortcomings: [0003] ① When pencils and erasers are used to draw paper forest fire situation maps on paper maps, the maps are easily damaged; [0004] ② Forest fire information needs to be manually fed back to the paper map, which is slow, heavy workload, and prone to position deviation and low accuracy; [0005] ③Manual drawing is used, the plotting information is not uniform, the sharing of plotting results is poor, and the forest fire situation map cannot be transmitted in real time. [0006] Therefore, when collecting forest fire points, the traditional forest fire plotting method is slow...
