【摘要】 海洋环境的监测对人类的生存环境与海洋经济的发展有着至关重要的作用。近年来随着海洋学的发展和研究日益深入,海洋环境的监测和调查研究工作越发受到人类的重视。本文研究的内容是黄海近海区海流信息的采集与管理,设计开发了一套基于WebGIS最优路径导航的海流数据采集管理开放式平台。平台引入Google Maps实现了动态直观的在地图上显示采集的数据信息,用户可实时监测采集信息及设备状况。本文在地图显示模块中设计实现出海导航的功能。通过一种改进的最小权匹配算法求出TSP问题的最优哈密顿回路,实现了从出海点出发,按照最优路径指示回收所有设备后返回,大大节省了出海费用。本文通过制定数据通信协议实现了平台的共享性,使任何遵照通讯协议的用户均可以实现数据的上报,所有满足该通信协议的项目都可以使用该系统管理采集海洋数据。用户根据角色权限差别使用该平台,实现了海洋信息共享。平台分为海流信息采集系统和海流信息管理系统两部分:海流信息采集系统通过上位机与智能采集设备的数据通信采集数据;海流信息管理系统选用B/S作为系统开发的架构模式,实现海流信息显示和管理,具有良好的开放性和扩展性。根据用户需求分析与系统设计目标的要求,主要分为信息采集和信息管理两部分,其中信息采集系统包括协议规范制定、监听接收信息、传送命令信息、信息过滤处理等子模块;信息管理系统包括用户登录注册模块、采集数据查询模块、设备管理模块、地图显示模块、警报处理模块、数据管理模块、项目管理模块、用户管理模块等。平台采用Java、JSP作为开发语言,并通过JDBC中间件统一与底层SQL Server 2005数据库进行数据交互。海流数据信息管理子系统采用基于MVC模式的J2EE架构。在前台表现层,平台采用免费的Google Maps作为WebGIS的技术支持,通过jQuery操作Ajax,实现地图、页面数据交互的无刷新性,给用户带来良好体验。更多还原

【Abstract】 Monitoring the marine environment has a vital role on environment for the survival of humans and marine economic development. With more in-depth development and research on Oceanography in recent years, humans pay more attention to marine environmental monitoring and research work . The research contents of this paper are data collection and management system on ocean current information research projects in coastal zone of the Yellow Sea. This paper designs and develops an open platform for ocean current data collection and management based on WebGIS and optimal navigation path.The platform introduced Google Maps to realize a dynamic visual display of collected data on the maps. Users can capture real-time monitoring information and device status. This paper shows the design in map module to achieve the function of sea navigation. By a Improved minimum weight matching algorithm, the optimal TSP Hamiltonian loop is calculated in the paper. According to the instructions of the optimal path, people start from a point, recover all the equipment then return. It saves the cost.The data communication protocol is formulated to realized the sharing of the platform, so that the users who follow the protocol can realize the data communication. The projects which are in accord with the communication protocol can use the system to collect and manage the marine data. Users’permissions are based on different roles in the use of the platform, so the sharing of ocean information can be realized.Platform is divided into two parts:ocean current information collection system and ocean current information management system. ocean current information collection system collect data through the data communication of PC and intelligent collection equipment; Ocean current information management system uses B/S model as the framework for system development, to realize the display and management of ocean current information. It’s open and extensible .According to users’requirements and the objectives of system design objectives, the platform involves two systems: information collection and information management. Information collection system includes the protocol formulation module, information listening and receiving module, the command transmission module and information filtering processing module; Information management system includes user login and registration module, data collection query module, the device management module, the map display module, the alarm processing module, data management module, the project management module, user management module and so on.The platform uses Java and JSP as the development language, and realizes data interaction through the JDBC middleware and SQL Server 2005 database. Ocean current data management subsystem is based on J2EE architecture of MVC model. In the foreground presentation layer, the free Google Maps are used in the platform as a technology support of WebGIS. Operating Ajax through the jQuery can realize the maps and the interaction page of data without refreshing. It brings positive experience to users.更多还原
