【摘要】：船舶导航系统是以计算机和通信网络为基础,将外部导航传感器的信息进行综合处理、优化组合和快速计算分析。操作人员可以用获得船舶最佳位置、姿态、航行环境等信息,以辅助其顺利完成航海任务。但是随着现代船舶上装备的设备越来越多,以及各种设备在功能和操作上的独立性,整个船舶系统面临结构越来越复杂、操作繁琐、升级维护困难、信息共享难度大、可移动性差、扩展功能不强等诸多问题,为船舶系统信息集中查看和管理带来很大困难。传统的C/S体系结构(客户机/服务器)的船舶软件设计遇到诸多问题。本论文从体系结构开始,研究利用现代成熟的Web B/S (浏览器/服务器)体系结构模型来完成整个船舶系统综合信息服务功能。首先深入分析了的船舶综合导航系统组成结构,对常见的船舶导航系统装配的设备的电气特性、通信方式、通信速率、数据编码方式、通信内容、通信频率等进行了详细的研究,并对比船舶导航系统使用C/S体系结构设计和B/S体系结构在系统设计上的优缺点。从船舶系统的结构和数据通信方面研究了利用B/S体系结构应用的可行性。其次研究了常见B/S体系结构组成,并且对常用的服务器软件从功能、稳定性、安全性、扩展性以及技术支持方面进行了对比,最终选择了Apache作为Web服务器,MySQL作为数据库服务器、前端使用JavaScript脚本语言、后端使用PHP脚本来实现整个B/S体系结构,为系统功能服务。并且将系统划分为B/S体系的表现层,逻辑层和数据层三层结构。之后为了实现船舶系统软件的可扩展性,研究了使用MySQL数据库来描述整个系统的构成,利用脚本语言进行系统自动构建、自动扩展。用模块化的设计方法,将系统功能、数据和用户操作分离。最后利用Web语言设计了系统组成界面,实现系统菜单栏、设备信息显示栏、重要信息显示栏,展示最终的设计结果,并实现系统可扩展性等功能。
[Abstract]:Ship navigation system is based on computer and communication network, the information of external navigation sensor is processed synthetically, optimized combination and fast calculation and analysis. Operators can obtain the best position, attitude, navigation environment and other information to assist the successful completion of the mission. However, with more and more equipments being equipped on modern ships and the independence of all kinds of equipments in function and operation, the whole ship system is faced with more and more complicated structure, complicated operation, difficulty in upgrading and maintenance, and great difficulty in information sharing. Many problems, such as poor mobility and weak extensibility, bring great difficulties to the centralized view and management of ship system information. Traditional C / S architecture (client / server) ship software design encountered many problems. Starting with the architecture, this paper studies the application of the modern mature Web B / S (browser / Server) architecture model to complete the integrated information service function of the whole ship system. Firstly, the structure of ship integrated navigation system is deeply analyzed, and the electrical characteristics, communication mode, communication rate, data coding mode, communication content of the equipment assembled by common ship navigation system are analyzed. The communication frequency is studied in detail, and the advantages and disadvantages of C / S architecture design and B / S architecture design are compared. The feasibility of using B / S architecture is studied from the aspect of ship system structure and data communication. Secondly, the composition of common B / S architecture is studied, and the common server software is compared in function, stability, security, extensibility and technical support. Finally, Apache is chosen as Web server. MySQL is used as database server, JavaScript script language is used in front end and PHP script is used in back-end to realize the whole B / S architecture and serve the system function. The system is divided into three layers: representation layer, logic layer and data layer. Then, in order to realize the expansibility of ship system software, the MySQL database is used to describe the structure of the whole system, and the script language is used to build the system automatically and expand automatically. With the modular design method, the system functions, data and user operations are separated. Finally, the system composition interface is designed by using Web language to realize the functions of system menu bar, equipment information display bar, important information display bar, display the final design result, and realize the system expansibility and so on.
