Design of small unmanned boat for measuring vertical profile temperature, salinity and sound velocity

Abstract

A design of a small unmanned boat for measuring vertical profile temperature, salinity and sound velocity includes the steps: designing a contour and hardware system architecture of the small unmannedboat with a required boat body structure suitable for carrying a CTD (conductivity temperature depth) device; manufacturing the small unmanned boat and building a profile temperature, salinity and sound velocity measuring experimental device based on the small unmanned boat; designing an experimental measurement scheme and placing a CTD probe under a waterline of the unmanned boat to perform temperature, salinity and sound velocity profile measurement on an area to be measured. The design of the contour and hardware system architecture of the small unmanned boat includes a propulsion and power system meeting offshore detection requirements, acoustic imaging system design, an unmanned boat data transmission system and the like meeting the requirements of carrying of the CTD device and practical measurement. Marine temperature, salinity and sound velocity parameters are measured based on the small unmanned boat, a boat body has anti-pitching, stabilizing and splashing prevention effects, and seawater temperature, salinity, depth and sound velocity parameters are more flexibly and accurately measured.

Description

technical field [0001] The invention relates to the field of small unmanned ship measurement, in particular to a design of a small unmanned ship for measuring vertical profile temperature, salinity and sound velocity. Background technique [0002] As human beings pay more attention to the development of marine resources, more and more unmanned self-observation platforms are applied to the ocean, such as unmanned aerial vehicle (Unmanned Aerial Vehicle, UAV), autonomous underwater vehicle (Autonomous Underwater Vehicle, AUV), etc. . As a miniaturized, offshore high-stability, and highly flexible marine observation platform, unmanned ships integrate intelligent control, remote communication, detection and investigation, and removal of obstacles at sea. Its superiority is particularly prominent in the environment. [0003] Unmanned boats were first invented in 1898 by the famous scientist Nicola Truss. It first appeared in the public eye during World War II as a single-use g...

Problems solved by technology

Early unmanned boats were controlled by navigation signals sent by cables or motherships by radio, and the ability to operate autonomously was very limited
