Sky, ground and air integrated remaining fire monitoring method for forest fire

Abstract

The invention provides a sky, ground and air integrated remaining fire monitoring method for forest fire. The method is that an UAV (unmanned aerial vehicle), a ground walking robot and a control center are arranged; an infrared camera is arranged on the ground walking robot; a GPS receiver, an imaging spectrograph, an operating center and a PLC are arranged on the UAV; the topographic information and vegetation information are stored in the PLC; the GPS receiver is used for transmitting a positioning signal of the location of the UAV to the PLC; the PLC transmits the positioning signal, the topographic information and the vegetable information to the operating center; the UAV flies within 5 to 20m above the vegetation; the imaging spectrograph is used for shooting an earth surface hyperspectral image and transmits the hyperspectral image and the positioning information to the center; if the hyperspectral image shows an over-temperature area with the vegetation and suffering from fire, the super-temperature area is an abnormal point; the control center controls the robot to perform infrared recording close to the abnormal point, and then the control center confirms whether the abnormal point is the forest remaining fire occurring point according to the infrared image.

Description

technical field [0001] The invention relates to a forest fire monitoring method. Background technique [0002] Forest fires are very harmful to forests, so the forestry department attaches great importance to the monitoring of forest fires. Due to the large scale and large area of ​​forest fires, it is relatively easy to detect and monitor them. However, after the fire is extinguished, due to various reasons such as incomplete extinguishment, there may still be re-ignition and embers. The temperature of residual fire is generally low, the area is small, and the combustion is slow. It is difficult to find residual fire by monitoring means of fire monitoring. Contents of the invention [0003] The purpose of the present invention is to provide a forest fire residual fire monitoring method that can quickly and accurately judge the forest residual fire. [0004] The sky-ground-air integrated forest fire residual fire monitoring method of the present invention uses unmanned ...

Problems solved by technology

Due to the large size and large area of ​​forest fires, it is relatively easy to detect and monitor them.

However, after the fire is extinguished, due to various reasons such as incomplete extinguishment, it is still possible to re-ignite and cause residual fire.

The temperature of residual fire is generally low, the area is small, and the combustion is slow. It is difficult to find residual fire by monitoring the fire.
