摘 要

当今时代随着世界经济全球化的进行，伴随着我国提出的“一带一路”与海洋强国战略，航运业的发展迅速成长，保障船舶的航行安全就是保障航运业的健康发展，快速、准确读取、保存、显示航道水深深度信息正是保障船舶安全航行的必要因素之一。

通常船舶使用船用回声测深仪作为船舶航行时测量船底水深的仪器为船舶航行时提供水深数据参考，但是很少有保存水深数据的功能，而简易型的船载航行数据记录仪（S-VDR）并没有硬性规定记录水深信息，只有装载VDR的国际航行的客货船具备记录水深信息的功能，而航道水深数据的保存可以作为海事事故调查分析的重要依据，也可以作为开辟新航线的重要参考资料。

论文对航道水深数据这一因素，从研究航道水深数据的提取方式出发，探讨航道水深数据的多种提取方式。针对水深数据的存储方式的选择，论文从多个方面分析了不同存储方式的利弊。对于水深的深度数据显示，论文选取裕光轮(M.V CAPE SPLENDOR)一天中12小时的水深数据利用Excel、OriginPro以及Visual Basic对其进行了二维或三维的处理并显示。最后给出了一个综合水深测量的实例来说明自动提取水深数据系统及其实现自动提取水深数据的原理。

论文主要研究内容如下：

1.分析航道水深数据的多种提取技术，并重点研究了自动提取航道水深的技术；

2.探讨航道水深数据的几种存储技术，并重点使用了Visual Basic自动保存航道水深的技术；

3.探讨航道水深数据的不同显示方法，并进行了图形显示。

根据论文中提及的航道水深数据的提取、存储及显示技术，将航道水深数据与时间、地点等其他数据相结合，进行了多种形式的航道水深数据图形显示。

通过分析裕光轮(M.V CAPE SPLENDOR)一天中12小时的水深数据，对航道水深数据的提取、存储及显示技术进行了细致的研究，为将来海事事故调查的应用提供了理论支持，为开辟新航道的数据支撑提供了技术支持。

Abstract

In today's era, as the world economy globalization, with our country suggest "The Belt And Road" and Marine power strategy, rapid growth development of shipping business, ship’s navigation safety is guarantee for the healthy development of shipping business, rapid and accurate read, save, display the depth of the channel depth information is one of the necessary factor to ensure the safety of ship’s navigation.

Usually ship using Marine echo sounder as the ship bottom water depth measurement instruments to provide water depth data reference for ship’s navigation, but few have the function of saving water depth data, and the simple type of ship voyage data recorder (system S - VDR), and there is no compulsory rules to record depth information, only the system load VDR international voyage passenger and cargo ships have the function that records depth information, and the preservation of the channel depth data can be used as the important basis of maritime accident investigation and analysis, also can be used as essential reference sources in the opening of new lines.

Based on the analysis of the channel depth data, this paper discusses the methods of collecting channel depth data. This paper contrasts the advantages and disadvantages of different storage methods for water depth data from several aspects. As for the the water depth data display, this paper select the YuGuang ship (M.V CAPE SPLENDOR) 12 hours in a day of water depth data by using Excel, OriginPro, and Visual Basic on the 2 D or 3 D processing and display. Finally, an example of integrated depth measurement is given to illustrate the system of automatic acquisition of depth data and the principle of automatic acquisition of depth data.

The main research contents of this paper are as follows:

1. Analyze various extraction technologies of channel water depth data, and focus on the automatic extraction of channel water depth technology;

2. Discussed several storage technologies of channel water depth data, and mainly used Visual Basic to automatically save channel water depth;

3. Different display methods of channel water depth data were discussed and graphic display was carried out.

According to the extraction, storage and display technology of channel depth data mentioned in the paper. According to the collection, storage and display technology of channel depth data mentioned in the paper, the channel depth data is combined with other data such as time or place, and various forms of graphical display of channel depth data are carried out.

Through the analysis of YuGuang ship (M.V CAPE SPLENDOR) water depth data of 12 hours in a day of channel depth data collection, storage and display technology has carried on the detailed study, for the future application of maritime accident investigation provides theoretical support, to open up new channel data support provides the technical support.

Key Words：Channel depth data; Automatic extraction; Storage mode; The depth of the display
