【摘要】：表层漂流浮标由于体积小、重量轻、便于投放、操作简单、应用范围广、工作寿命长、成本合理等特点,而广泛应用于认识海洋、研究海洋以及开发利用海洋。但由于表层漂流浮标受到体积小、应用范围广、工作时间长、海洋环境复杂多变以及抛弃式仪器等条件限制,因此人们至今仍不断对表层漂流浮标进行各方面改进设计。本文提出一种小尺寸、工作可靠性高、操作简单、观测精度高、应用范围广、隐蔽性好、低功耗及低成本的新型表层漂流浮标。新型表层漂流浮标由水帆、定深系缆、全填充式表层漂流浮标浮标体以及定位通讯模块四部分组成。首先介绍了水帆的研制,并对水帆进行相关海上实验得出水帆的可靠性。然后论述全填充式表层漂流浮标浮标体的创新型设计,浮标体设计重点是运用SolidWorks和ANSYS软件对葫芦形与圆柱形浮标体建模开展了流体分析,得出葫芦形浮标体较过去常用的圆柱形及圆球形浮标体更具合理性、性能更优越;随后提出了全填充式表层漂流浮标浮标体的玻璃钢材质选择、发泡填充固定、表面疏水性以及隐蔽性方面的设计方法或改进方案。定位通讯模块的研制及实现是的难点及创新点,硬件设计时必须考虑整个系统的指标,包括系统功耗、GPS定位数据采集、铱星定位数据发送各个功能模块的关联等,为了实现低功耗,选取了大量具有低功耗、高性能特征的芯片;在软件设计时论述了系统值班电路的实现,为了实现低功耗目的,定位通讯模块长期处于睡眠状态,当到达工作时间时通过DS3231芯片进行唤醒功能,又根据GPS定位数据采集和铱星定位数据发送的主要工作要求,提出相应设计方案,并实现系统初次上电检验和上位机通讯软件的设计方案,最后通过实验验证定位通讯模块的可行性。并对新型表层漂流浮标整体系统进行论述,由于新型表层漂流浮标已经应用于实际水体调查中,可以初步认定新型表层漂流浮标可以更好地满足水体综合调查观测需求。
[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.
