【摘要】：当前世界处于高速发展时期，随之而来的是人类对资源的大量消耗，陆地上的可再生资源已经越来越少，而占据地球表面百分之七十左右的海洋则拥有极其丰富的资源，比如化学能、波浪能以及滨海、深海海底蕴藏的矿产资源等等。开发海洋资源已经是世界各国的共同选择，但必须看到开发海洋资源的巨大难度，对海洋环境的了解程度决定了对海洋资源开发的难度。信标机作为一种用于辅助收回监测海洋环境的潜标系统等的设备越来越受到重视，它可使设备的收回更加高效、方便。本文针对信标机的功能特性，设计了两套不同工作方式、不同功能特点的信标机系统，旨在根据不同的使用环境，，不同的使用要求，应用不同的信标机，来提高潜标系统等设备的收回效率，从而推动海洋环境监测技术的发展。两套不同工作方式的信标机分别是：高亮LED指示与无线测向方式同时具备的信标机以及高亮LED指示与铱星通讯(GPS定位)方式同时具备的信标机。本文主要对以下几部分做了详细介绍：首先，本文分析了国内外信标机产品的研发现状及趋势，针对信标机工作的特殊海洋环境，提出了两种不同工作方式、功能特点的信标机系统，并大致阐述了主要的研究内容。其次，通过分析国外相关产品的性能特点，提出了课题设计信标机系统的性能指标，并给出了系统的总体方案以及课题设计的主要特点；针对系统中用到的关键技术做了详细介绍，同时给出了关键模块的选型。再次，给出了系统的总体硬件、软件设计框图。硬件设计部分，针对重要的硬件模块电路：STM32主控制器电路、电源电路、XBee模块电路、铱星模块电路、GPS模块电路、液晶模块驱动电路、信号强度指示电路等给出了详细介绍，同时给出了系统的密封技术以及耐压仓底部开关结构设计。软件设计部分，同样针对重要的功能模块：铱星模块通讯、XBee模块通讯、GPS模块通讯、液晶驱动以及系统软件低功耗等设计给出了详细的程序流程图与具体实现方法。最后，从硬件、软件两部分对系统进行了调试，并在实验室环境下，整体测试了系统的功能，验证了本论文设计的信标机系统达到了最初设计的要求，同时总结了课题设计，给出了系统设计的不足之处与接下来可以改善的地方。
[Abstract]:The world is in a period of rapid development, followed by a large amount of human consumption of resources, renewable resources on land has become less and less, and the oceans occupying about 70% of the earth's surface have extremely rich resources. Such as chemical energy, wave energy and coastal, deep seabed mineral resources and so on. The exploitation of marine resources has been the common choice of all countries in the world, but it must be seen that it is very difficult to develop marine resources, and the degree of understanding of marine environment determines the difficulty of exploitation of marine resources. As a kind of equipment which can be used to retract and monitor the marine environment, beacons have attracted more and more attention. It can make the recovery of the equipment more efficient and convenient. According to the function characteristic of beacon machine, this paper designs two sets of beacon machine system with different working mode and different function characteristic, aiming to apply different beacon machine according to different use environment and different use requirement. To improve the recovery efficiency of submarkage system and other equipment, and promote the development of marine environmental monitoring technology. The two sets of beacons with different working modes are the beacons with both highlight LED indication and wireless direction-finding mode, and the beacons with high-light LED indication and Iridium satellite communication GPS positioning mode at the same time. This paper mainly introduces the following parts in detail: firstly, this paper analyzes the current situation and trend of the research and development of beacons at home and abroad, and puts forward two different working methods aiming at the special marine environment of beacons. Function characteristic of beacon machine system, and described the main research content. Secondly, by analyzing the performance characteristics of foreign related products, the performance index of the beacons system is put forward, and the overall scheme of the system and the main features of the subject design are given. The key technologies used in the system are introduced in detail, and the selection of key modules is also given. Thirdly, the overall hardware and software design block diagram of the system is given. In the hardware design part, the main controller circuit of the important hardware module: 1: STM32, the power supply circuit and XBee module circuit, the Iridium module circuit and GPS module circuit, the liquid crystal module driving circuit, the signal intensity indicating circuit and so on, are introduced in detail. At the same time, the sealing technology of the system and the structure design of the bottom switch of the pressure tank are given. In the part of software design, the detailed program flow chart and realization method are also given for the important function modules: Iridium module communication, XBee module communication, GPS module communication, liquid crystal drive and low power consumption of system software. Finally, the system is debugged from the hardware and software, and the function of the system is tested in the laboratory environment. It is verified that the beacon system designed in this paper has reached the requirements of the original design, and summed up the design of the subject. The deficiency of the system design and the place that can be improved in the following are given.
