Problems solved by technology

Therefore, the physical parameters related to the ice properties change within a certain range, which causes large errors and uncertainties in the actual measurement method; the second is to rely on the reflection time of ultrasonic waves and lasers when they reach the ice interface, and calculate The distance from the interface, the actual measurement accuracy is affected by the local surface fluctuations, and the change of thickness needs to be reflected on the surface and bottom of the ice layer; the third is direct measurement. The thickness of coastal ice is usually measured with ice drills and ice rulers. Simple and reliable, but fixed-point timing observation cannot be achieved, and it cannot be carried out when the sea ice is too thin to bear the weight of the observer, so it is dangerous

Embodiment 1

[0034] Such as figure 1 and 2 As shown, an ice element monitoring UAV in this embodiment is mainly composed of a UAV body 1, an ice thickness measuring electric drilling device 2 and a visible light high-definition digital camera 3 and the like.

[0035] In this embodiment, the unmanned aerial vehicle adopts a four-rotor structure, and the unmanned aerial vehicle landing gear 101 is designed as an amphibious landing gear. It is made of lightweight materials and is designed in the shape of a sled. The ice surface breaks and falls into the water, and it can still float on the water surface, and this design can ensure that there is enough contact area between the drone and the ice surface, thereby reducing the pressure on the ice surface, thereby reducing the probability of the ice surface breaking. In addition, enough The large contact area can also ensure the friction force between the UAV and the ice surface, so that there can be enough friction force when the ice thickness mea...

Embodiment 2

[0043] A kind of ice condition element monitoring unmanned aerial vehicle of this embodiment, its basic structure is identical with embodiment 1, and its difference is: it replaces visible light high-definition digital camera 3 with thermal infrared camera, and its advantage is that can be in night, fog The detection of ice conditions in hazy or smoky conditions increases the adaptability in special weather conditions. In addition, the use of thermal infrared cameras can also obtain ice condition information of ice surface temperature.

Embodiment 3

[0045] An ice monitoring UAV in this embodiment, the UAV body in this embodiment is a fixed-wing UAV, and the payload device adopts a digital camera and an infrared camera, and is equipped with a cloud platform, which can realize the remote control camera angle on the ground change. In this embodiment, the fixed-wing unmanned aerial vehicle cannot be equipped with electric drilling equipment for ice thickness measurement, but it can use digital cameras and infrared cameras to observe elements such as sea ice density, total amount of ice, ice type, ice shape, and ice surface temperature. It can take advantage of the advantages of fast speed and large coverage of fixed-wing aircraft.

Description

technical field [0001] The invention relates to the field of ice condition monitoring, in particular to an unmanned aerial vehicle for monitoring ice condition elements. Background technique: [0002] Seawater freezing occurs every winter in the Bohai Sea and the northern part of the Yellow Sea in my country. The sea ice in the Bohai Sea and the Yellow Sea is one of the important marine disasters in my country. Affected by the warm and cold weather in winter, the severity of sea ice varies every year. In severe cases, sea ice can overturn offshore oil platforms, damage port facilities, block waterways, damage ships, and paralyze maritime transportation, causing huge damage to offshore facilities. Destruction and loss; especially for the primary marine industry dominated by marine fishery, the ice on the sea surface led to the suspension of production of the marine fishing industry, the mariculture industry was affected, and a large number of ships were damaged, which seriou...
