An underwater terrain measurement device based on vertical take-off and landing fixed-wing amphibious UAV

Abstract

The present invention provides an underwater terrain measurement device based on a vertical take-off and landing fixed-wing amphibious UAV, including an amphibious UAV, a GPS reference station, a main control device and a remote control device, and the remote control device, the main control device and the amphibious The UAV is connected by wireless communication, and the remote control device and the main control device are used to control the operation of the amphibious UAV on the shore of the measured waters; It can navigate on the water surface during surveying and mapping; the amphibious UAV is equipped with a depth sounder and an airborne GPS rover, wherein the airborne GPS rover cooperates with the GPS reference station to obtain plane coordinates, and the depth sounder is used for amphibious drones. The man-machine acquires water depth data while navigating on the water surface. The invention can efficiently go deep into dangerous and complex waters and carry out operations, and can meet the needs of underwater terrain measurement of medium and small rivers, lakes and reservoirs.

Description

technical field [0001] The invention relates to the technical field of underwater terrain measurement equipment, in particular to an underwater terrain measurement device based on a vertical take-off and landing fixed-wing amphibious unmanned aerial vehicle, which is suitable for automatic measurement of underwater terrain in the context of steep banks. Landing fixed-wing amphibious aircraft is a water propulsion carrier, using GPS system and single-beam sounding system to detect the underwater terrain of small and medium-sized rivers and lakes. Background technique [0002] Underwater topographic surveying is the process of using surveying instruments to determine the three-dimensional coordinates of underwater points, and it is an important part of river, lake, and seabed surveying. Its key links are bathymetry and positioning. Bathymetry is to measure the height from the bottom point to the water surface, and to measure the depth of the depth points (called bathymetric po...

Problems solved by technology

Carrying it on manned ships or unmanned ships is the main working method of underwater topographic survey at present. However, in the application of manned ships, there are problems such as inconvenient measurement of nearshore shoals, difficulty in obtaining suitable ships, and hidden dangers to personnel safety; The surveying boat system can perfectly solve the problem of shallow water surveying, and can also be used in dangerous waters to ensure the safety of ships and personnel. It not only affects work efficiency, but also endangers the safety of equipment and personnel in severe cases. There is no effective solution at present
