Problems solved by technology

4. Satellite remote sensing, using polar-orbiting meteorological satellites, land resource satellites, geostationary satellites, and low-orbit satellites to detect forest fires. This program has a wide range of detection, fast data collection, and continuous data. It is not affected by terrain conditions and has clear images. However, the use of satellite remote sensing will occupy a large amount of data, and it is difficult to detect fire hazards in the early stage

Embodiment Construction

[0020] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0021] see figure 1 , the forest fire early warning system based on the mid-infrared laser of the present invention includes: a mid-infrared laser radar 5, a signal processing and wireless transmission module 6, a monitoring system including a camera 3, and a monitoring and dispatching center 8. Among them, the mid-infrared lidar 5 includes a mid-infrared laser, which is the core detection device of the entire system. It is preferably installed on a base station iron tower 1 with a suitable height, and the mid-infrared lidar 5 can rotate 360 ​​degrees and the pitch angle can be adjusted. To ensure that the detection range is an area with a radius of 6 km centered on the position of the mid-infrared laser radar 5 , and there is no dead angle for detection within this range. The signal processing and wireless transmitting module 6 is respo...

Abstract

The invention discloses a forest fire remote early detection warning system based on an intermediate infrared laser. The forest fire remote early detection warning system comprises a intermediate infrared laser radar device, a signal processing and wireless transmitting module, a monitoring system and a monitoring and dispatching center. The forest fire remote early detection warning system has the advantages that the intermediate infrared laser is adopted as a laser radar light source, safe, low-loss, remote and high-precision detection is achieved, the effective detection range reaches the radius being 6 km, effective early fire prevention is carried out on forest coverage within 100 square kilometers, remote control, intelligentization, flexibility and the like of forest fire detection are ensured, and fire early warning is improved to the maximum extent; due to the intermediate infrared laser capable of generating three wavelengths at the same time, accuracy and precision of fire detection are improved, and reliability is high.

Description

technical field [0001] The invention relates to a forest fire early warning system, in particular to a forest fire early warning system based on a mid-infrared laser. Background technique [0002] Forest fire is a natural disaster that is sudden, destructive, and difficult to deal with and rescue. Therefore, forest fire prevention is very important. At present, the main developed foreign forest fire protection technologies are as follows: Germany adopts the FIRE-WATCH forest fire automatic early warning system, and the system has a monitoring radius of 10 kilometers. However, the accuracy of the system is low, and it requires a lot of manpower, material and financial resources on the ground to verify. The United States uses forest ranger aircraft and infrared remote sensing fire early warning aircraft to patrol and the "Earth" satellite to orbit the earth at an orbit of about 705 kilometers above the ground for detection, but this plan costs a lot. Canada uses a satellite p...
