基于GIS的船舶监控系统的设计和实现

The Design and Development of Ship Monitoring System Base on GIS

本文首先介绍了基于GIS的船舶监控系统的需求和总体设计。系统的设计使用多层体系结构将系统分为5层:包含传统的表示层、业务逻辑层、数据库层,还包含了数据访问层和表示选择层,而且这两层是以组件的方式实现具有很大的通用性;系统的体系结构风格是异构体系风格的"查改有别"模型即混合使用了C/S和B/S体系结构风格,然后在系统的实现部分详细介绍了基于XML的子模块插件化技术的实现,最后简单介绍了系统的特色子模块的实现。

This paper introduces the Design and Requirement of a ship monitoring System base on GIS at f irst. The design of our system is the multi-layer architecture that divides the system into f ive layers:UI layer,UI locator layer,business layer,data access layer and database layer. The UI locator layer and data access layer was implemented with component can be reused in other system or platform. The software architecture style of our system was designed as isomerous architecture style that uses the C/S style to query module and B/S style to modif ication module. In the last part of this paper we discuss the implement of plug-in technology base on XML and the implement of special module of our system in detail.
