Global experts are calling on countries to meet their zero-zero targets and stop climate change, which has a major impact on the recent wave of wildfires, as rising temperatures cause more moisture to evaporate from the soil, drying out soil and plant growth make more resilient. Flammable if its spark is ignited.
According to the British newspaper, “Daily Mail”, scientists and engineers have developed a set of new technologies that can help predict and treat these devastating fires.
These include computer models that map potential fire paths, drones that drop water, and autonomous robots that can locate fire sources and spray water. Here we list the available technologies in points:
1. Artificial intelligence techniques
A common problem with wildfires is that by the time they are detected, they are already widespread and causing significant destruction, so some companies have developed artificial intelligence (AI) tools that can detect fires in their early stages using satellite images.
US-based Descartes Laboratories and OroraTech Laboratories look for detectable signs, such as smoke or changes in thermal infrared data, in satellite images of problem areas every few minutes.
Algorithms trained to look for different characteristics of forest fires are then run, and if one is detected, its coordinates are sent to fire officials. Available technologies can automatically detect when a fire actually starts, and this is very useful in remote areas. or especially vulnerable. areas..
AI can also predict how a fire will grow and move once it starts, and is widely used in fire-prone countries such as the United States, Canada, Spain, Portugal and Australia.
Tools like WIFIRE Firemap in the US can help authorities plan evacuations and make judgments about the best way to deal with the growing fire.
The models use real-time data from satellites such as weather, terrain and drought, along with cameras and sensors on the ground and aircraft equipped with infrared radars, and can tell firefighters the location, pace and direction of a fire.
Large, classic aircraft dedicated to detecting or fighting forest fires struggle to see in the dark and thick smoke, putting their crews at risk, while remote-controlled drones offer a solution, as they can capture data in real time and responders from can inform far down.
Firefighting aircraft can be equipped with thermal imaging cameras that capture wind direction and high-resolution images of smoke and other variables, are easy to pack and transport, and can be deployed to remote locations.
Drones can also deliver water to affected sites to help fight the fire directly, which is the vision of the Spanish company Drone Hopper with its Wild Hopper drone.
The Wild Hopper is also equipped with thermal cameras that can first help detect the fire and assess the type of fire, and send the data back to the control units.
It can then hover over a designated combustion zone and spread 600 gallons of liquid cargo as a mist specifically designed for the type of fire below.
Experts deploy remote-controlled robots in burning wilderness to confront fires from the ground, the Dronster from Spanish firefighting equipment manufacturer Vallfirest has been designed, and the forest cutter robot is equipped with an excavator that can create trenches that can prevent the spread of fire, while critical collection is collected. data such as humidity and temperature.
It is also capable of transporting equipment to remote areas, keeping the wounded away from sites of destruction, and the robots can be remotely controlled to distribute extinguishing fluids at distances of up to 62 meters.
A prototype of an autonomous fire robot that can make intelligent decisions was also developed at New York University, where students built the machine that uses information from onboard sensors to navigate without hitting obstacles, has an arm with ‘ a nozzle connected to a water tank and a temperature sensing camera.
The arm moves and uses its camera to search for the heat source, before aiming the nozzle and spraying water directly onto the fire.
The FlameRanger from Swedish robotics company Unifire uses similar technology to detect hot spots before deploying up to 5,000 liters of water or foam per minute.
His commercial robot has thermal imaging and flame detection sensors attached to nozzles on the robot arms.
