Nowadays, unmanned aerial vehicles (UAVs) are playing an important role in maritime emergency rescue systems. They can search for rescuers on the sea surface in a short period of time and transmit high-definition video to the command center to make a reasonable rescue plan.  

The role of drones in sea rescue:

1. Search and location

Drone search technology combines radio frequency technology with personal location-based search to enable remote search and rescue. The search system is mainly composed of seven parts: UAV, pan-head camera, map transmission, location search and rescue equipment, beacon, detector and ground station. Beacons are critical, and the application of the system in sea rescue requires that the crew have a beacon in their life-saving equipment. During search and rescue, the equipment equipped with the UAV can activate the beacon within a range of 15 kilometers, send back the information of the crew involved in the accident, and quickly carry out satellite positioning. Compared with the traditional search and rescue ship, UAV search and rescue has a wide field of vision, high efficiency, all-weather, strong mobility.

2. Remote video transmission

Figure the equipment has good ability of diffraction, the system time delay is small, the transmission distance can be up to 10 to 30 kilometers, uavs equipped with remote video transmission system of the unmanned aerial vehicle (uav) found in ships and victims of the accident by searching the positioning system, can be loaded hd yuntai camera video real-time transmission to the command department in time, so as to formulate reasonable rescue package, Improve the efficiency and success rate of search and rescue.

3. Delivery of food and medical equipment

Most maritime accidents in recent years have involved small vessels and vessels transporting sand and rock. Life-saving configurations on this type of ship are very simple. Therefore, in the event of an accident, search and rescue patrol ships are difficult to find them accurately, greatly reducing the efficiency of search and rescue. In addition, the Marine environment is complex, vulnerable to hunger and injury, and vulnerable people can be life-threatening at any time. In this case, the use of drones is very important. Drones can be fitted with the necessary food and water, as well as medical equipment, to make search and rescue much more efficient.

In a word, UAV search and rescue has the advantages of low cost, high flexibility and high efficiency, and has already met the needs of current maritime search and rescue activities. Drones can transmit the status of a ship in distress to a command center in real time via a remote video transmission function, making it easier to plan and conduct search and rescue operations. Therefore, the application of UAVs in maritime search and rescue greatly improves the efficiency and should be widely used.
