Video acquisition, transmission and reproduction system for deep-sea manned submersible

Abstract

The invention discloses a deep sea manned submersible video acquisition, transmission and reproduction system, which relates to the technical field of submersible and comprises a manned cabin external high-definition camera group, a manned cabin external video cabin, a manned cabin internal video box and a plurality of video displays. The manned cabin external high-definition camera group is used for generating multi-channel video signals and transmitting the multi-channel video signals to the manned cabin external video cabin through optical fibers; the manned cabin outer video cabin and the manned cabin inner video box carry out signal transmission through a watertight optical cable, and the manned cabin outer video cabin is used for converting multi-channel video signals into single-channel optical signals with time information and transmitting the single-channel optical signals to the manned cabin inner video box; the video box in the manned cabin is connected with the plurality of video displays through a network, and the video box in the manned cabin is used for converting a single-path optical signal with time information into a plurality of paths of optical signals, screening out effective video signals, decoding the effective video signals and displaying the decoded effective video signals on the video displays. The system has the advantages of being small in video transmission delay, not prone to interference and small in occupied cabin penetrating hole.

Description

Technical field [0001] The present invention relates to the field of submersible technologies, in particular, a deep sea-raised submersible video acquisition, transmission, and reproducing system. Background technique [0002] The deep sea-saving submersible is an important equipment that leads the development of deep-sea equipment related technologies and industry chain. It can be equipped with scientists and engineering technicians to visit the seabed. Through professional observation, analysis and operation, carry out such as deep sea book test, salvage rescue And detection and maintenance and other job tasks. my country has developed successful "Zhenlong", "Deep Sea Warrior" and "Strugglers", three deep sea-saving submersible, among which "Strugglers" can perform various tasks in the whole sea. [0003] Due to the huge water pressure limit on deep sea, the deep sea-raised submersible generally uses the spherical pressure tank as the manned cabin, and the viewing window is res...

AI Technical Summary

Problems solved by technology

This method has the following problems: under the action of high water pressure, the transmission rate of these cables for transmitting electrical signals will be seriously affected, resulting in problems such as large video transmission delays and reduced clarity; The complex electromagnetic environment generated will cause great interference to the video transmission and affect the video quality; the videos of all the cameras must be centrally transmitted to the manned cabin for display and storage, and the cables will occupy the valuable manned cabin penetration holes. As a result, the number of penetration holes increases, the processing difficulty of the manned cabin is increased, and the safety of the structure and sealing are reduced
