【摘要】：海上任何活動(dòng)都離不開實(shí)時(shí)準(zhǔn)確的海洋環(huán)境信息保障,而海洋環(huán)境信息的獲取必須依靠可靠、高效、經(jīng)濟(jì)的海洋觀測(cè)技術(shù),無(wú)纜定點(diǎn)剖面儀就是一種新型的海洋觀測(cè)裝備,它除了可以像Argo浮標(biāo)一樣通過(guò)調(diào)節(jié)浮力改變排水體積實(shí)現(xiàn)在深海大洋中上浮或下潛外,還能夠在浮出水面時(shí),根據(jù)獲得的衛(wèi)星定位信息與預(yù)定位置比較,如若超出限定值,則在下一次下潛過(guò)程中自動(dòng)進(jìn)行控位操作,以使無(wú)纜剖面儀向預(yù)定區(qū)域航行修正,從而實(shí)現(xiàn)不依靠纜繩系留,自主地固定在特定海域進(jìn)行長(zhǎng)期、連續(xù)、定點(diǎn)垂直剖面觀測(cè)。本文主要研究與無(wú)纜定點(diǎn)剖面儀控位相關(guān)的總體技術(shù)。設(shè)計(jì)了剖面儀的主體外形和鰭舵;進(jìn)行流體動(dòng)力計(jì)算分析,得到了剖面儀常用工況下的各流體動(dòng)力參數(shù)并通過(guò)拖曳水池試驗(yàn)進(jìn)行驗(yàn)證;建立了剖面儀在浮力驅(qū)動(dòng)下豎直運(yùn)動(dòng)的數(shù)學(xué)模型,利用運(yùn)動(dòng)學(xué)仿真程序完成了剖面儀控位運(yùn)動(dòng)的仿真計(jì)算,分析各控制參數(shù)對(duì)剖面儀控位運(yùn)動(dòng)特性的影響規(guī)律;針對(duì)對(duì)剖面儀控位運(yùn)動(dòng)起關(guān)鍵作用的浮力驅(qū)動(dòng)技術(shù)展開研究,確定了最大浮力調(diào)節(jié)量、完成了浮力調(diào)節(jié)裝置工作流程、系統(tǒng)回路設(shè)計(jì)和總體布置;結(jié)合剖面儀湖上試驗(yàn),驗(yàn)證了剖面儀設(shè)計(jì)、建模、仿真的正確性和功能實(shí)現(xiàn)的有效性。而與無(wú)纜剖面儀控位運(yùn)動(dòng)有關(guān)的控制策略、控制流程、衛(wèi)星定位等,可以直接引用或借鑒水下滑翔機(jī)的技術(shù)成果,本文在此不再贅述。
[Abstract]:Any activity at sea can not be separated from the guarantee of real-time and accurate marine environmental information, and the acquisition of marine environmental information must depend on reliable, efficient and economical ocean observation technology. The cable-free fixed-point profiler is a new type of marine observation equipment. In addition to being able to float or dive in the deep ocean by adjusting buoyancy and changing the volume of drainage, like the Argo buoy, it can also be compared with a predetermined position on the basis of available satellite positioning information when surfacing, if the limit is exceeded. Then the position control operation is carried out automatically in the next submersible process, so that the cable-less profiler can navigate to the predetermined area, so as to realize the long-term, continuous, fixed-point vertical section observation without relying on the cable mooring and fixing independently in the specific sea area. This paper mainly studies the overall technology related to the position control of the cable-free fixed-point profiler. The main body shape and fin rudder of the profiler are designed, the hydrodynamic parameters of the profiler under common working conditions are obtained and verified by towing tank test. The mathematical model of vertical motion of profiler driven by buoyancy is established. The simulation calculation of the control motion of profiler is completed by using kinematics simulation program, and the influence of control parameters on the motion characteristics of profiler is analyzed. Aiming at the research on the buoyancy driving technology which plays a key role in the control of the profiler motion, the maximum buoyancy regulation quantity is determined, and the work flow of the buoyancy regulating device, the system loop design and the general arrangement are completed, and the experiment on the lake of the profiler is carried out. The correctness of the design, modeling and simulation of the profiler and the validity of the function realization are verified. However, the control strategy, control flow, satellite positioning and so on related to the position control motion of the non-cable profiler can be directly cited or used for reference from the technical achievements of the underwater glider, which will not be discussed in this paper.
