为了探索深海,不同类型的深海运载装备得以成功开发,并应用于深海科学、资源勘探开发、工程保障及战略安全等不同领域。深海运载装备可以分为载人潜水器(HOV)、遥控深潜器(ROV)、自治式深潜器(AUV)及混合型深潜器,其中以载人潜水器为代表的高技术装备群成为建设海洋强国的重要保障力量。文章对美国"阿尔文"号、俄罗斯"和平I"号和"和平II"号、日本"深海6500"号、法国"鹦鹉螺"号、中国"蛟龙"号载人潜水器运行管理机制进行了阐述,综合比较其优缺点,提出了建立职业化运行保障队伍、优化作业流程,创新组织结构、探索多型潜水器海上作业模式等运行管理机制构架的建议。 相似文献

为加快我国潜水器的发展尤其是业务化应用,保障我国深海大洋科考工作的顺利开展,文章梳理美国伍兹霍尔海洋研究所和我国主要潜水器的技术指标和应用情况,并通过对比提出我国的优势和不足。研究结果表明:载人潜水器方面,我国"蛟龙"号在平均下潜深度的关键指标上领先于美国"Alvin"号,但由于发展较晚,在下潜次数等方面远远落后;无人有缆式潜水器方面,我国"海龙"系列正处于作业磨合期,在最大水下航速方面与美国"Jason"号差距较大;无人自治式潜水器方面,我国"潜龙"系列与美国"Sentry"号和"REMUS"系列差距不大,但在小型潜水器协同化作业和系列化生产等方面存在不足;复合型潜水器方面,我国"海龙11000"号与美国"NEREUS"号和"NUI"号差距不大,但应提升载荷和冰下作业能力;水下滑翔机方面,我国"海翼"号与美国"Spray"号和"Slocum"号差距不大,且即将业务化应用;我国应通过完善海洋技术装备运行机制和积极开展海上科考航次任务,不断积累潜水器作业经验。 相似文献

This paper thoroughly studies a control system with control allocation for a manned submersible in deep sea being developed in China.The proposed control system consists of a neural-network-based direct adaptive controller and a dynamic control allocation module.A control energy cost function is used as the optimization criteria of the control allocation module,and weighted pseudo-inverse is used to find the solution of the control allocation problem.In the presence of bounded unknown disturbance and neural networks approximation error,stability of the closed-loop control system of manned submersible is proved with Lyaponov theory.The feasibility and validity of the proposed control system is further verified through experiments conducted on a semi-physical simulation platform for the manned submersible in deep sea. 相似文献

In this paper, a robust path following control law is proposed for a deep-sea manned submersible maneuvering along a predeterminated path. Developed in China, the submersible is underactuated in the horizontal plane in that it is actuated by two perpendicular thrusts in this plane. The advanced non-singular terminal sliding mode （NTSM） is implemented for the design of the path following controller, which can ensure the convergence of the motion system in finite time and improve its robustness against parametric uncertainties and environmental disturbances. In the process of controller design, the close-loop stability is considered and proved by Lyapunov＇ s stability theory. With the experimental data, numerical simulations are provided to verify the control law for path following of the deep-sea manned submersible. 相似文献

China''s 7000 m manned submersible JIAOLONG carried out an exploration cruise at the Mariana Trench from June to July 2016. The submersible completed nine manned dives on the north and south area of the Mariana Trench from the depth of 5500 to 6700 m, to investigate the geological, biological and chemical characteristics in the hadal area. During the cruise, JIAOLONG deployed a gas-tight serial sampler to collect the water near the sea bottom regularly. Five days later, the sub located the sampler in another dive and retrieved it successfully from the same location, which is the first time that scientists and engineers finished the high accuracy in-situ deployment and retrieval using a manned submersible with Ultra-Short Base Line (USBL) positioning system at the depth more than 6600 m. In this task, we used not only the USBL system of the manned submersible but also a compound strategy, including five position marks, the sea floor terrain, the depth contour, and the heading of the sub. This paper introduces the compound strategy of the target deployment and retrieval with the practical diving experience of JIAOLONG, and provides a promising technique for other underwater vehicles such as manned submersible or Remote Operated Vehicle (ROV) under similar conditions. 相似文献

High-resolution mapping of large gas emitting mud volcanoes on the Egyptian continental margin (Nile Deep Sea Fan) by AUV surveys 总被引：4，自引：1，他引：3

Two highly active mud volcanoes located in 990–1,265 m water depths were mapped on the northern Egyptian continental slope
during the BIONIL expedition of R/V Meteor in October 2006. High-resolution swath bathymetry and backscatter imagery were
acquired with an autonomous underwater vehicle (AUV)-mounted multibeam echosounder, operating at a frequency of 200 kHz. Data
allowed for the construction of ~1 m pixel bathymetry and backscatter maps. The newly produced maps provide details of the
seabed morphology and texture, and insights into the formation of the two mud volcanoes. They also contain key indicators
on the distribution of seepage and its tectonic control. The acquisition of high-resolution seafloor bathymetry and acoustic
imagery maps with an AUV-mounted multibeam echosounder fills the gap in spatial scale between conventional multibeam data
collected from a surface vessel and in situ video observations made from a manned submersible or a remotely operating vehicle. 相似文献

从1948年法国设计FNRS-2号第一艘深潜器以来,特别是六十年代开始,由于海洋开发和军事上的需要,对深潜器(又称可潜器)给予了广泛重视。目前,深潜器已成为海洋调查、海底打捞、深海救生、海洋研究以及建造各种水下工程的重要手段。美国1970年下水的深潜救生艇(DSRV)全部采用计算机程序控制。可以在1524米水深援救失事海艇艇员,每次24人,化费研制费高达二亿多美元。三艘“南鱼座”号深潜器,在一年内把沉没在深750米海底的120条鱼雷打捞起来。深潜工作艇“阿尔文”号和“CURV”号把失落在深856米海底的一颗氢弹打捞起来。著名深潜器“阿鲁明纳”号和打捞船“密执尔”号合作打捞了沉没在深1538米的另一艘深潜器“阿尔文”号。 相似文献
