【摘要】：表層漂流浮標由于體積小、重量輕、便于投放、操作簡單、應(yīng)用范圍廣、工作壽命長、成本合理等特點,而廣泛應(yīng)用于認識海洋、研究海洋以及開發(fā)利用海洋。但由于表層漂流浮標受到體積小、應(yīng)用范圍廣、工作時間長、海洋環(huán)境復雜多變以及拋棄式儀器等條件限制,因此人們至今仍不斷對表層漂流浮標進行各方面改進設(shè)計。本文提出一種小尺寸、工作可靠性高、操作簡單、觀測精度高、應(yīng)用范圍廣、隱蔽性好、低功耗及低成本的新型表層漂流浮標。新型表層漂流浮標由水帆、定深系纜、全填充式表層漂流浮標浮標體以及定位通訊模塊四部分組成。首先介紹了水帆的研制,并對水帆進行相關(guān)海上實驗得出水帆的可靠性。然后論述全填充式表層漂流浮標浮標體的創(chuàng)新型設(shè)計,浮標體設(shè)計重點是運用SolidWorks和ANSYS軟件對葫蘆形與圓柱形浮標體建模開展了流體分析,得出葫蘆形浮標體較過去常用的圓柱形及圓球形浮標體更具合理性、性能更優(yōu)越;隨后提出了全填充式表層漂流浮標浮標體的玻璃鋼材質(zhì)選擇、發(fā)泡填充固定、表面疏水性以及隱蔽性方面的設(shè)計方法或改進方案。定位通訊模塊的研制及實現(xiàn)是的難點及創(chuàng)新點,硬件設(shè)計時必須考慮整個系統(tǒng)的指標,包括系統(tǒng)功耗、GPS定位數(shù)據(jù)采集、銥星定位數(shù)據(jù)發(fā)送各個功能模塊的關(guān)聯(lián)等,為了實現(xiàn)低功耗,選取了大量具有低功耗、高性能特征的芯片;在軟件設(shè)計時論述了系統(tǒng)值班電路的實現(xiàn),為了實現(xiàn)低功耗目的,定位通訊模塊長期處于睡眠狀態(tài),當?shù)竭_工作時間時通過DS3231芯片進行喚醒功能,又根據(jù)GPS定位數(shù)據(jù)采集和銥星定位數(shù)據(jù)發(fā)送的主要工作要求,提出相應(yīng)設(shè)計方案,并實現(xiàn)系統(tǒng)初次上電檢驗和上位機通訊軟件的設(shè)計方案,最后通過實驗驗證定位通訊模塊的可行性。并對新型表層漂流浮標整體系統(tǒng)進行論述,由于新型表層漂流浮標已經(jīng)應(yīng)用于實際水體調(diào)查中,可以初步認定新型表層漂流浮標可以更好地滿足水體綜合調(diào)查觀測需求。
[Abstract]:Surface floating buoys are widely used in understanding the ocean because of their small size, light weight, easy to put in, simple operation, wide application range, long working life, reasonable cost and so on. But the surface floating buoys are limited by such conditions as small size, wide application, long working hours, complex marine environment and jettisoned instruments, etc. So people are still improving the design of surface floating buoy in various aspects. This paper presents a small size, high reliability, simple operation, high observation precision, wide application range and good concealment. A new type of surface floating buoy with low power consumption and low cost. The new surface floating buoy is composed of water sail, fixed depth mooring cable, fully filled surface floating buoy body and positioning communication module. Firstly, the development of water sail is introduced. The reliability of water sail is obtained by sea experiments. Then the innovative design of fully filled surface floating buoy body is discussed. The design emphasis of the buoy body is to use SolidWorks and ANSYS software to model the hoist and cylindrical buoy. The results show that the hoist buoy is more reasonable than the cylindrical and spherical buoys used in the past, and its performance is better than that of the cylindrical and spherical buoys used in the past. Then, the selection of glass fiber reinforced plastic (FRP) material for the surface floating buoy with full filling is proposed, and the foam filling is fixed. The design method or improvement scheme of surface hydrophobicity and concealment. The development and realization of positioning communication module is the difficulty and innovation point. The hardware design must consider the index of the whole system, including the system power consumption and GPS positioning data acquisition. In order to realize low power consumption, a large number of chips with low power consumption and high performance characteristics are selected. The positioning communication module is in the sleep state for a long time. When the working time arrives, it wakes up by DS3231 chip. According to the main work requirements of GPS positioning data collection and Iridium satellite positioning data transmission, the corresponding design scheme is put forward. Finally, the feasibility of the positioning communication module is verified by experiments. The whole system of the new surface floating buoy is discussed. Since the new surface floating buoy has been applied to the investigation of the actual water body, it can be preliminarily concluded that the new surface floating buoy can better meet the needs of the comprehensive investigation and observation of the water body.
