Analysis of deep sea submersible technology development based on patent analysis

Deep-sea submersibles are important equipment for entering the deep sea, winning the initiative to compete in marine strategic resources and maintaining the interests of deep-sea safety. It is of great significance to study the development trend of its technology. This article analyzes the technical development status of deep-sea submersibles based on patent data from the three dimensions of patent application trends, patent rights national distribution and patent technology life cycle. And through the patent owner"s technology focus analysis of its patent technology composition, combined with the patent text to analyze the development trend of key technology of deep-sea submersibles. Research has shown that: in terms of patent applications, China has achieved simultaneous development with the world, showing a rapid growth trend; patented technologies in this field are in the technological growth stage, and global patent applications mainly focus on underwater navigation and communication, path planning and safe obstacle avoidance, and there are three aspects to the overall design of the submersible, and there is still much room for technological development. Among them, underwater navigation and communication technologies are mainly developed around improving navigation accuracy and communication reliability; path planning and safe obstacle avoidance technologies focus on environmental modeling and optimization search, and real-time dynamic obstacle avoidance as research and development hotspots, focusing on optimality , feasibility and real-time issues; The overall design of the submersible is researched and developed for the purpose of shortening the diving time, improving the underwater operation time and endurance.
