Problems solved by technology

If ordinary optical fibers are used, reaching the full sea depth of 11,000 meters requires a bulky optical fiber system, which uses a winch for retraction and is equipped with a smooth ring with a pressure resistance of 10,000 meters, which makes the entire system cost extremely high

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 Shown is the system connection diagram of the optical fiber test system of the present invention.

[0023] Jointly debug the entire fiber optic system on the mother ship, so that the image of the watertight camera can be transmitted back to the surface console. If the image cannot be transmitted back to the surface console normally, check each joint and fiber fusion joint to ensure that the image can be stably transmitted back to the console. .

[0024] Such as figure 2 Shown is a schematic diagram of the mother ship heave compensation device of the present invention.

[0025] A heave compensation device is added to the system, the neutral buoyancy block is connected to the optical fiber release group on the water surface, the gravity block is fixed on the optical fiber armored cable, and the buoyancy block and the ...

Abstract

The invention relates to the field of underwater robots, and specifically relates to a myriameter ARV optical fiber system. The system comprises a water surface console, a heave compensating device, and an optical fiber connecting system, and the water surface console is used for displaying image information acquired by an underwater camera in real time. The system can compensate the heave movement of a mother ship and prevent fiber twisting by employing devices of a gravity block and a neutral buoyancy block; compared with an optical fiber winch release system, two optical fiber group release mechanisms are advantaged by small size and low cost, the interference of ocean current can be prevented to a certain extent, when the tension of the optical fiber is increased due to the influence of the ocean current, the mechanism can reduce the influence of the ocean current on ARV vehicle navigation, and the optical fiber joint on the water surface is effectively prevented from being broken due to over-large tension; and the system has universality so that the system is applicable to the underwater robots of different types.

Description

technical field [0001] The invention relates to underwater robot technology, in particular to a 10,000-meter ARV optical fiber system. Background technique [0002] ARV not only has the function of AUV large-area underwater detection and search, but also can be manually controlled in real time like ROV through micro-optical cables, and can display image information in real time, so it is more and more widely used in the ocean. The 10,000-meter ARV represents the advanced level of national marine development, and many countries have invested a lot of manpower and material resources in the development of the 10,000-meter ARV. There is no 10,000-meter ARV system in my country so far, so the study of 10,000-meter ARV has great national strategic significance. [0003] The underwater communication system is an important part of the 10,000-meter ARV, and the usual practice is to use optical fiber for communication. If ordinary optical fibers are used, a bulky optical fiber syste...
