Problems solved by technology

[0003] For a long time in the past in our country, forest fire monitoring has mainly been the way of watchtowers. With the improvement of scientific and technological level, my country's forestry resource security technology has gradually developed from traditional artificial to intelligent direction, but there are still some limitations at present. Sexual issues need to be addressed

Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The present invention is a remote sensing detection system for detecting wild forest and grassland fires, such as figure 1 As shown, including transmitting system, receiving system, spectral analysis system and data acquisition processor 2-10;

[0036] The emission system includes laser 2-1; using micro-pulse laser, the selected wavelength is 532nm, micro-pulse, high repetition frequency (10KHz), single pulse energy <20μJ, high safety factor for human eyes, and will not cause risks to large-scale field detection .

[0037] The receiving system includes a telescope 2-2. The telescope 2-2 is a large-aperture telescope. The telescope 2-2 is a symmetrical reflective telescope. The produced 400mm Schmidt-Cassegrain telescope, the telescope 2-2 is used to receive the scattered light emitted by the laser 2-1 after the laser is scattered by ...

Abstract

The invention discloses a remote sensing detection system for detecting field forest and grassland fire. The remote sensing detection system comprises a transmitting system, a receiving system, a spectral analysis system and a data acquisition processor; the transmitting system comprises a laser; the receiving system comprises a telescope; the spectral analysis system comprises a collimating mirror and a dichroic mirror which are sequentially arranged on a light path of a light beam emitted by the telescope; a first narrow-band filter and a first converging mirror are sequentially arranged on a transmission light path of the dichroic mirror, the first converging mirror converges the light to a first detector; a second narrow-band filter and a second converging mirror are sequentially arranged on a reflected light path of the dichroic mirror, the second converging mirror converges the light to a second detector; and the first photoelectric detector and the second photoelectric detector are both in signal connection with the data acquisition processor. The invention also discloses a remote sensing detection method for detecting field forest and grassland fire. The method has the characteristics of high detection sensitivity and large detection range.

Description

technical field [0001] The invention belongs to the technical field of remote sensing monitoring and fire detection, relates to a remote sensing detection system for detecting wild forest and grassland fires, and also relates to a remote sensing detection method for detecting wild forest and grassland fires. Background technique [0002] The frequency of forest or grassland fires has increased dramatically in recent decades. Most of the forest fires are burning out of control under the synergy of human factors and natural factors. All kinds of species in the forest are ruthlessly devoured in these forest fires, and the balance and stability of the earth's ecosystem have encountered huge challenges. Challenges, the combustion process produces a large amount of smoke and dust, which is harmful to the atmospheric environment, affects the local climate and even poses a huge threat to the living environment of human beings, causing heavy losses to the country and people's lives a...
