【摘要】：船舶试航是新船出厂前的一个重要测试过程,其目的在于测试船舶的航行性能,并对船舶设计方的设计做出评价,同时这些船舶实际航行的测试资料,可以为设计方设计新船舶时提供参考。近年来,由于船舶制造业的大力发展,新船产量的大幅度增长,使得传统船舶试航技术的局限性日益加重。目前应用的船舶试航系统由于存在性能稳定性差、数据存储安全性不高、人机交互界面不友好等问题,制约了船舶试航技术的发展。随着计算机技术与通信技术的飞速发展,开发一套符合现今技术发展的GPS新船舶试航系统正成为解决这一问题的有效途径,它通过GPS定位技术定位试验船舶位置,在人机界面中显示船舶航行轨迹信息,能够使得试航人员直观了解船舶性能。同时,在系统内部完成一部分船舶试航项目数据的计算,省去了人工计算的麻烦,提高了试航报告的产出效率。本文应用GPS定位技术及计算机软件设计技术,以船舶试航为设计依据,研究与设计了GPS新船舶试航系统。论文首先深入研究了国内外船舶试航系统设计与开发的发展现状和实现技术,在此基础上,提出了基于GPS定位技术,结合MFC技术SQL Sever数据库Google Map的系统设计方案。文中分析了试航项目的需求,给出了该系统的系统模块划分及功能设计,并采用了MFC多线程技术、SQL Sever数据库技术及ODBC数据库互联技术实现了整个系统的串口通信与数据存储部分,包括GPS数据串口通信、系统数据存储、数据调用等功能。同时以MFC可视化编程和Google Map技术实现了系统人机交互与航迹绘制部分的开发,其中包括人机交互界面、Google Map显示及航迹绘制。其中,通过测试系统各模块功能,包括GPS串口接收、串口数据处理、数据库存储、人机交互界面使用、Google Map载入、轨迹绘制等操作,实现了整个试航系统功能。系统数据部分的多线程编程及数据库存储,大大提高了数据的安全性能；在人机交互界面使用中,人性化的串口参数设置、工况参数设置及试航项目菜单的设计,方便了试航人员操作,结合Google Map技术中的地图图形拖拉、缩放等功能操作,使得系统交互性能大步提升。
[Abstract]:Ship trial is an important test process before the new ship leaves the factory. Its purpose is to test the navigation performance of the ship, and to evaluate the design of the ship designer, and at the same time, to make the test data of the actual navigation of these ships. In recent years, due to the rapid development of shipbuilding industry, the output of new ships has increased by a large margin. The limitation of traditional ship trial technology is becoming more and more serious. At present, the ship trial system has some problems such as poor performance stability, low security of data storage, unfriendly man-machine interface and so on. With the rapid development of computer technology and communication technology, it is becoming an effective way to solve this problem to develop a set of GPS new ship trial navigation system which accords with the development of current technology. It uses the GPS positioning technology to locate the position of the test ship and displays the information of the ship's navigation track in the man-machine interface, which can make the test crew know the ship's performance directly. At the same time. A part of ship trial project data is calculated in the system, which saves the trouble of manual calculation and improves the efficiency of ship trial report. In this paper, GPS positioning technology and computer software design technology are used to design ship trial. This paper studies and designs the new ship trial system of GPS. Firstly, this paper deeply studies the present situation and the realization technology of the design and development of the ship trial system at home and abroad. On this basis, the positioning technology based on GPS is put forward. The system design scheme of SQL Sever database Google Map based on MFC technology is introduced. The requirements of the trial navigation project are analyzed, and the system module partition and function design are given. The serial communication and data storage of the whole system are realized by using MFC multithreading technology and ODBC database interconnection technology. Including GPS data serial communication, system data storage. At the same time, using MFC visual programming and Google Map technology to realize the development of human-computer interaction and track drawing, including man-machine interface. Google Map display and track drawing. Among them, through the test system module functions, including GPS serial port receiving, serial port data processing, database storage, man-machine interface using Map loading, trajectory drawing operations. The function of the whole trial navigation system is realized. The multi-thread programming and the database storage of the data part of the system greatly improve the security performance of the data. In the man-machine interaction interface, the humanized serial port parameter setting, the operating condition parameter setting and the navigation trial item menu design are convenient for the operator to operate. Combined with the Google Map technology map graphics drag-and-drop, zoom and other functions to make the system interactive can be greatly improved.
