What role can UAV play in flood control and disaster relief?


Recently, many places into the flood control and disaster relief emergency state. So, as an important emergency rescue equipment
 UAV, what role can it play in this emergency state?

1. Can UAV Fly on Rainy Days?
The answer is definitely. At present, many types of aircraft of DJI and other brands have achieved the IP67 waterproof rating, which can prevent liquid immersion for a short time, and fly as usual light rain days. There is also a brand specializing in waterproof drones — Swellpro, which can realize UAV take off in rainy days or at the surface of the water. It is also equipped with waterproof camera, the throwing device and other loads, with waterproof remote control, and can also be flipped on the water surface, which is convenient for rescue applications in rainy days.

2. 
Throw Rescue Supplies
As mentioned above, the throw facility is already equipped with loads for several UAVs. DJI drones have loads such as parabolic boxes, and more drones have the dropper device that can fly over personnel to drop supplies such as a life buoy. After several years of development, drone logistics has made great progress, and many companies use logistics drones to deliver materials effortlessly . Due to the flexible flying characteristics of drones, there are many people in reality using simple modified drones, such as using a rope to hang supplies to fly over the location of the rescue workers, which can also realize the function of transporting relief materials.


3. Aerial Reconnaissance
The high-definition zoom camera carried by the drone can not only realize the reconnaissance under visible light, but also use the infrared lens to view the personnel, dam and other conditions in the case of inconvenient lighting such as night, but also directly send the pictures to the flood control headquarters through the network broadcast, for the relevant leaders to understand the scene situation in the first time, to make the rescue decision deployment.


4. Point Positioning
The drone is equipped with a laser sensor, which can quickly identify the positioning of the waiting rescue personnel, and send the location back through the Internet, so that the rescuers can go to the rescue in the first time, thus greatly improving the efficiency and effect of the rescue. If rescuers need aerial reconnaissance forces, they can also call the support of drones to help them better carry out rescue work.

5. Night Illumination
Drones can be equipped with searchlights to provide lighting at night to facilitate search and rescue and reconnaissance. The tethered UAV can be raised into the air and charged through the ground module, thus greatly improving the time in the air, ensuring more than 10 hours of lighting time, and ensuring the smooth progress of the construction and emergency rescue of emergency personnel.


6. Communication Relay
If communication facilities are damaged due to floods and other disasters, so that the communication is interrupted, China's domestic Wing Loong UAV can not only fly to assist the ground to check the damage to the communication facilities, provide information decision for rapid maintenance, but also directly serve as communication relay to provide communication support services for the coverage area. 


7. Propaganda Rescue
Propaganda rescue can help rescue workers guide the affected people on the ground to cooperate with the rescue, issue flood warnings around reservoirs, rivers and other locations, and broadcast rescue information to stabilize the emotions of the affected people.

8. Spray Epidemic Prevention Agents
In order to prevent the occurrence of a major epidemics after a major disaster, after the flood receded, the affected area needs to be extensively sprayed with disinfection agents to prevent the occurrence of epidemic diseases. At this time, the plant protection drones can be used to help spray all kinds of disinfection agents.
