【摘要】：當前世界處于高速發(fā)展時期，隨之而來的是人類對資源的大量消耗，陸地上的可再生資源已經越來越少，而占據地球表面百分之七十左右的海洋則擁有極其豐富的資源，比如化學能、波浪能以及濱海、深海海底蘊藏的礦產資源等等。開發(fā)海洋資源已經是世界各國的共同選擇，但必須看到開發(fā)海洋資源的巨大難度，，對海洋環(huán)境的了解程度決定了對海洋資源開發(fā)的難度。信標機作為一種用于輔助收回監(jiān)測海洋環(huán)境的潛標系統(tǒng)等的設備越來越受到重視，它可使設備的收回更加高效、方便。 本文針對信標機的功能特性，設計了兩套不同工作方式、不同功能特點的信標機系統(tǒng)，旨在根據不同的使用環(huán)境，不同的使用要求，應用不同的信標機，來提高潛標系統(tǒng)等設備的收回效率，從而推動海洋環(huán)境監(jiān)測技術的發(fā)展。兩套不同工作方式的信標機分別是：高亮LED指示與無線測向方式同時具備的信標機以及高亮LED指示與銥星通訊(GPS定位)方式同時具備的信標機。本文主要對以下幾部分做了詳細介紹： 首先，本文分析了國內外信標機產品的研發(fā)現狀及趨勢，針對信標機工作的特殊海洋環(huán)境，提出了兩種不同工作方式、功能特點的信標機系統(tǒng)，并大致闡述了主要的研究內容。 其次，通過分析國外相關產品的性能特點，提出了課題設計信標機系統(tǒng)的性能指標，并給出了系統(tǒng)的總體方案以及課題設計的主要特點；針對系統(tǒng)中用到的關鍵技術做了詳細介紹，同時給出了關鍵模塊的選型。 再次，給出了系統(tǒng)的總體硬件、軟件設計框圖。硬件設計部分，針對重要的硬件模塊電路：STM32主控制器電路、電源電路、XBee模塊電路、銥星模塊電路、GPS模塊電路、液晶模塊驅動電路、信號強度指示電路等給出了詳細介紹，同時給出了系統(tǒng)的密封技術以及耐壓倉底部開關結構設計。軟件設計部分，同樣針對重要的功能模塊：銥星模塊通訊、XBee模塊通訊、GPS模塊通訊、液晶驅動以及系統(tǒng)軟件低功耗等設計給出了詳細的程序流程圖與具體實現方法。 最后，從硬件、軟件兩部分對系統(tǒng)進行了調試，并在實驗室環(huán)境下，整體測試了系統(tǒng)的功能，驗證了本論文設計的信標機系統(tǒng)達到了最初設計的要求，同時總結了課題設計，給出了系統(tǒng)設計的不足之處與接下來可以改善的地方。
[Abstract]:At present, the world is in a period of rapid development, which is followed by a large amount of human consumption of resources. The renewable resources on land have become less and less, and the oceans, which occupy about seventy percent of the earth's surface, have extremely rich resources, such as chemical energy, wave energy and seashore, mineral resources in the deep sea and so on. Marine resources have been the common choice of all countries in the world, but the difficulty of developing marine resources must be seen. The degree of understanding of the marine environment determines the difficulty in the development of marine resources. The beacon machine, as a submersible system used to assist in the recovery and monitoring of the marine environment, is becoming more and more important. It can make the equipment retracted. More efficient and convenient.
In this paper, aiming at the functional characteristics of beacon, two sets of beacon systems with different working modes and different functions are designed to improve the recovery efficiency of the submersible system according to the different use environment, different use requirements and different beacon machines, thus promoting the development of marine environmental monitoring technology. Two sets of different work are carried out. The beacon machines are: beacon machines with high LED indication and wireless direction finding methods, and beacons with high brightness LED instructions and iridium communication (GPS positioning). This article is a detailed introduction to the following parts:
First, this paper analyzes the current situation and trend of the research and development of beacon machine products at home and abroad. In view of the special marine environment of the beacon machine, two kinds of beacon systems with different working modes and functional characteristics are put forward, and the main contents of the research are roughly described.
Secondly, by analyzing the performance characteristics of foreign related products, the performance index of the project design beacon system is put forward, the overall scheme of the system and the main features of the design are given. The key technologies used in the system are introduced in detail. At the same time, the selection of key key modules is given.
Thirdly, the overall hardware of the system, the block diagram of the software design and the hardware design are given. In view of the important hardware module circuit, the STM32 main controller circuit, the power supply circuit, the XBee module circuit, the iridium module circuit, the GPS module circuit, the liquid crystal module drive circuit, the signal strength indicator circuit and so on are introduced in detail, and the system is also given. The design of the sealing technology and the bottom switch structure of the pressure storehouse. The software design section also gives detailed program flow chart and implement method for the important functional 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 two parts of 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 original design requirements. At the same time, the design of the project is summed up, and the inadequacies of the system design and the next place to be improved are also given.
