A deep sea concealed relay communication device

Abstract

The invention relates to a deep-sea concealed relay communication device. The deep-sea concealed relay communication device comprises a water-permeable compartment, an expandable oil bag is mounted in the water-permeable compartment, a depthometer and a sound velocity profiler are mounted on the top of the water-permeable compartment, the bottom of the water-permeable compartment extends to form a rectangular shell, a buoyancy control compartment, a pressure-proof oil tank, an electronic compartment, a pressure-proof battery compartment and an acoustic omnidirectional transducer are mounted in the shell separately sequentially from top to bottom, and a pressure-proof oil pipe passes through the buoyancy control compartment to enter the pressure-proof oil tank. The deep-sea concealed relay communication device is compact and reasonable in structure and convenient to operate and can be mainly used for remote high-rate concealed underwater sound communication between large-scale deep-sea platforms and AUVs (autonomous underwater vehicles) for executing tasks.

Description

technical field [0001] The invention relates to the technical field of deep sea equipment, in particular to a deep sea concealed relay communication device. Background technique [0002] Building a maritime power is a national strategy. In 2012, the 18th National Congress of the Communist Party of China put forward the grand strategic goal of "improving the ability to develop marine resources, developing the marine economy, protecting the marine ecological environment, resolutely safeguarding the country's marine rights and interests, and building a marine power". Developing oceanic blue land and expanding living and development space has become the national strategy of coastal countries in the world. [0003] Ocean research, development and utilization are inseparable from marine engineering equipment. The development of marine engineering equipment is conducive to supporting the country's marine and land demands from a scientific point of view and promoting the strategy ...

Problems solved by technology

[0004] The published invention patent (CN 103112550A) of "a deep-sea communication relay buoy" can realize communication between large-scale deep-sea platforms and the water surface, real-time calibration of underwater positions, etc., but it does not have the function of underwater communication and cannot realize deep-sea Underwater Acoustic Communication Function between Carrier Platform and AUV

[0005] The disclosed "a method and device for long-distance underwater acoustic communication" (CN 102122993A) can realize the function of underwater long-distance communication, but has the following disadvantages (1) long-distance communication needs to pass through the radio communication channel of the surface buoy, The concealment is poor; (2) The deep sea acoustic channel is not used, but the shallow sea acoustic channel is used, which is greatly affected by the reflection of the sea surface, the channel is unstable, the noise is large, the communication distance is short, and the communication quality is difficult to guarantee; (3) Due to the short communication distance, a large number of buoy devices are required to realize long-distance transmission; (4) The buoy has a single function and does not have buoyancy adjustment capability
