OBSERVATION SYSTEM OF MEASUREMENT THE SEA CIRCUMSTANCES AND AERIAL VEHICLE WITH UNMANNED AND METHODS THEREOF}

The present invention uses a drone to quickly observe a large area of the marine environment, in particular, since the drone that observes the sea wirelessly through the mobile communication network of the land to expand the activity radius and adjust by remote control and various The present invention relates to a marine environment observation system, an unmanned aerial vehicle, and an operation method for observing a wide maritime area in real time using an optical camera.

Korea has three (3) planes on the top of the sea, and has many economic effects from the nearby ocean. In particular, when such marine resources are polluted or temperature changes occur, the reality is directly or indirectly affected by the surrounding climate and living environment.

In addition, due to land development and industrialization, land soil flows into nearby oceans, or various environmental pollutants are introduced or dumped, causing marine pollution.

As such, the sea, especially the surrounding marine environment, is directly or indirectly intimately connected with real life due to the topographical conditions of Korea, where the three sides are in contact with the sea.

It is important to prevent the inflow of soil from the land, the introduction of various environmental pollution blisters, and the dumping of the environment. However, the nature of the marine environment is not limited by the rapid change of the sea temperature due to global warming and abnormal temperature. In some cases, the marine environment may be severely altered due to its influence and unavoidable circumstances.

In Korea, which is surrounded by the sea on three sides, the area of the ocean to be monitored or observed was large, making it difficult to quickly and accurately monitor the ocean. In particular, it required a lot of professional manpower and cost to monitor and observe the ocean using a flying vehicle.

Therefore, it is necessary to develop a technology for observing and surveying the large marine environment around Korea quickly and accurately.

According to the prior art, the marine environment survey of Korea is a method of photographing and analyzing a sea with a strange signal such as color change by observing a wide sea in the sky with an expert personnel on board an aircraft.

However, the number of technical personnel with expertise is relatively small and it takes a long time to be skilled at the same time, and the sea area to be investigated is very wide, and the sea has severe climate change, so the dates for securing safe flights are very limited. It is often difficult to conduct the necessary surveys and observations when needed. In addition, continuous observation in real time is very difficult due to rapid climate change at sea.
