基于组件技术的渔业电子海图系统设计与实现

基于对国内外渔业电子海图系统发展现状的研究,提出了开发新型渔业电子海图系统的构成、总体方案和功能模型,采用IHO S-57海图国际标准即海道测量数据传输标准(Transfer Standard for Digital Hydrographic Data)的电子海图,介绍了应用Visual C++2010开发环境和ECIVMS组件进行系统开发的关键技术和方法。本系统的设计与实现结果表明,软件已实现了海图物标图层显示、渔业信息查询、渔区数据库管理、渔区及作业安全等深线标绘、遥感影像加载,实时潮汐计算及海况信息叠加显示等主要功能,为渔业信息组网服务及构建一体化信息获取、存储、处理、表达、传输和发布平台提供了基础支持。

Design and Implementation of Fishery Electronic Chart System Based on Component Technology

T he constitution ,general scheme and functional model of a new fishery elec‐tronic chart system are presented based on the research of development status of fishery electronic chart system at home and abroad ,and the key technologies and methods for developing this system by using Visual C++ 2010 development environment and ECIVMS component are introduced on the basis of the electronic chart with IHO S‐57 chart international standard (i .e .the Transfer Standard for Digital Hydrographic Da‐ta) .The design and implementation of the system show that several main functions such as display of chart object layer ,query of fishery information ,management of fishing da‐tabase ,isobath setting for fishery safety operation ,loading of remote sensing image ,re‐al‐time calculation of tide and superposition and display of sea state information are real‐ized by the software ,and basic support would be provided both for the fishery informa‐tion networking and services and for the platform construction for the acquisition ,stor‐age ,processing ,expression ,transmission and release of integrated information .
