水下沉船精确定位系统的研制

Development of precise positioning system for underwater wreck

为提高水下沉船定位的精确性,使得海上沉船的搜救工作能够更顺利的进行,本文研究沉船定位相关的系统问题。本研究采取超短基线定位系统,并对其相关系统的部件和功能进行阐述,重点研究机器人(ROV)和超短基线系统的关联系统,分析沉船信息采集系统、数据传输处理系统、数据校正系统等。最后推导出整个系统的定位精度。研究结果表明,该定位系统不仅能够提高水下沉船定位的精确性,同时也能够降低潜水员水下作业危险性以及提高沉船搜救成功率,更为水下沉船定位的研究提供理论指导和一定参考价值。

In order to improve the accuracy of underwater wreck location,this paper makes a special study on the system of the problem of the navigation system. This study focuses on the system of robot( ROV) and ultra short baseline system,and analyzes the information acquisition system,data transmission system and data correction system. The research results show that this system can not only improve the accuracy of underwater wreck location,but also can reduce the risk of underwater operations and improve the success rate of the search and rescue. What's more,it provides theoretical guidance and reference value for the research of underwater wreck location.
