【摘要】：二十一世纪是人类开发利用海洋的时代，海洋是人类生活必不可少的物质和能源的源泉。随着科学技术的发展，人们对海洋重要性的认识和海洋资源环境的开发不断深入，邻海各国对我国海域的非法侵犯活动频发，提高对海上环境的实时监测能力，维护我国的领海安全是当下急需解决的课题。大型海洋资料浮标是海洋监测的重要手段之一，，它可以全天候、长期连续、定点地对海洋环境进行监测，对我国海洋事业的发展起着积极的作用。我国目前已业务化运行的大型海洋资料浮标主要是对海洋气象水文数据进行监测，本课题依托海洋公益性项目——海洋维权执法目标探测识别与信息传输技术应用研究，研制出一套新型的大型海洋浮标系统，在东海特定敏感区域进行示范应用。该系统研究的主要任务是利用在已有的大型资料浮标上加装声学传感器阵列和高清晰度图像采集系统，通过采用高速无线数据传输系统，对定点获取的浮标周边海域活动舰船声指纹及图像信息进行分析与研究，为侵权目标的识别与判断提供依据。本论文研究的主要内容是海上目标探测识别浮标的高速数据通讯与数据接收处理系统，通过利用高速无线数据传输系统建立起集数据接收、数据存储、实时显示、数据查询、系统设置、数据分析于一体的岸站系统软件平台。本论文首先对浮标系统的整体设计方案做了简要介绍；其次详细论述了浮标系统的通讯模块，根据CDMA和海事卫星的通信原理，制定出详细的网络协议；然后依据关系数据库标准与优化设计原则,以SQLServer2005为数据库平台创建了具有良好性能的数据库；最后采用VC++面向对象编程技术，完成软件功能的开发与设计。本论文还通过10m浮标获取的波浪资料对海浪频谱进行了研究分析，尝试了在大型浮标上利用VC++编程进行海浪谱的计算方法研究并结合MATLAB混合编程绘制海浪频谱曲线，为今后在大型浮标上计算海浪谱打下了基础。目前，本设计已经完成实验室实验、拷机测试和几个月的海上实验，软件系统对数据的接收、存储、处理及海浪谱分析等功能均能正常实现，人机交互界面友好并且具有良好的可扩展性，系统运行稳定，数据接收准确，满足项目各方面的需求。另外软件开发遵循模块化设计，便于进行后期的二次开发利用。
[Abstract]:21th century is the era of human exploitation and utilization of the ocean, which is an indispensable material and energy source for human life. With the development of science and technology, people have a deep understanding of the importance of the ocean and the exploitation of marine resources and environment. The frequent illegal encroachment of neighboring countries on our sea area, the enhancement of real-time monitoring capability of marine environment, and the maintenance of the safety of our territorial waters are urgent issues. Large ocean data buoys are one of the important means of ocean monitoring. It can monitor the marine environment all weather, continuously for a long time, and it plays an active role in the development of marine industry in China. At present, the large ocean data buoy in operation in our country is mainly used to monitor marine meteorological and hydrological data. This subject relies on the research on the application of ocean public welfare project-detection, identification and information transmission technology of marine rights enforcement. A new type of large ocean buoy system has been developed. The main task of this system is to install acoustic sensor array and high definition image acquisition system on the existing large data buoys, and to adopt a high-speed wireless data transmission system. The acoustic fingerprints and image information of moving ships in the sea area around buoys are analyzed and studied, which provides the basis for the identification and judgment of tort targets. The main content of this paper is the high-speed data communication and data receiving and processing system for marine target detection and identification buoy. Through the use of high-speed wireless data transmission system, set up data reception, data storage, real-time display, data query. This paper firstly introduces the overall design of the buoy system, and then discusses the communication module of the buoy system in detail, according to the communication principle of CDMA and maritime satellite. The detailed network protocol is worked out, and then according to the relational database standard and the optimization design principle, the database with good performance is created on the platform of SQLServer2005. Finally, the object-oriented programming technology of VC is adopted. Complete the development and design of software function. In this paper, the wave spectrum is analyzed by the wave data obtained from the 10m buoy, and the calculation method of the wave spectrum is studied by using VC programming on the large buoy, and the wave spectrum curve is drawn with MATLAB mixed programming. It will lay a foundation for the calculation of wave spectrum on large buoys in the future. At present, the design has completed the laboratory experiments, the testing of copying machines and several months of offshore experiments, and the functions of the software system to receive, store, process and analyze the wave spectrum can be realized normally. The man-machine interface is friendly and has good expansibility, the system runs stably, the data receives accurately, and meets the requirements of all aspects of the project. In addition, the software development follows the modular design, which is convenient for the secondary development and utilization in the later stage.
