Problems solved by technology

However, its limitations are that due to the limitation of storage space, it is impossible to continuously collect, store and record underwater acoustic signals for a long time; in addition, its acquisition and storage consumes a lot of power, and the battery capacity is insufficient, so it cannot stay in the sea for a long time to record underwater acoustic signals; and, due to its durability The design of the ballast tank is not enough to withstand pressure, so it cannot be placed in 10,000-meter deep water for underwater acoustic signal recording

Description

technical field [0001] The present application belongs to the field of marine acoustics, and in particular relates to a large-capacity storage device for long-term, high-speed acquisition of underwater acoustic signals. Background technique [0002] With the development and utilization of my country's oceans moving to the deep sea, the marine acoustic observation technology has expanded from the shallow sea to the deep sea, which is a major demand for understanding, utilizing and developing the deep sea. In view of the lack of technically effective means of acquiring deep-sea acoustic information in China, this application solves the long-term, low-noise signal acquisition and storage technology, provides reliable acoustic recording equipment for abyss scientific expeditions, and improves my country's deep-sea acoustic equipment manufacturing capabilities. [0003] At present, my country has carried out the research and development of deep-sea self-contained underwater acous...
