Underwater topographic survey device based on vertical take-off and landing fixed-wing amphibious unmanned aerial vehicle

Abstract

The invention provides an underwater topographic survey device based on a vertical take-off and landing fixed-wing amphibious unmanned aerial vehicle. The underwater topographic survey device comprises an amphibious unmanned aerial vehicle, a GPS base station, a main control device and a remote control device, wherein the remote control device, the main control device and the amphibious unmanned aerial vehicle are in wireless communication connection; the remote control device and the main control device are used for controlling the amphibious unmanned aerial vehicle to work on a measured water area bank; the amphibious unmanned aerial vehicle can vertically take off and land on the land or on the water surface and can sail on the water surface during underwater surveying and mapping; a depth finder and an airborne GPS moving station are installed on the amphibious unmanned aerial vehicle; the airborne GPS moving station is matched with the GPS base station to be used for obtaining plane coordinates; and the depth finder is used for obtaining water depth data when the amphibious unmanned aerial vehicle sails on the water surface. The device can efficiently go deep into dangerous and complex water areas and carry out operations, and can meet the requirements of underwater topography 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
