【摘要】：为了适应信息时代的发展,改善高校实验室硬件设施不足、实验场地受限的情况,满足高等教育资源共享、开放办学的变革要求,虚拟仿真实验室教学已成为现代实验教学改革的必要选择。在计算机和网络通信技术的基础上提出搭建一个可视化网上航迹融合仿真实验系统。为了使学生充分了解信息融合技术在海上目标跟踪领域的应用,学习雷达与船舶自动识别系统AIS(Automatic Identification System)信息融合处理过程及原理,加深对相关知识的认识与应用,开发一套可以实现多个客户端与服务器端同时建立通信的仿真系统。利用网络通信技术、虚拟软件技术、数据库技术、虚拟仿真技术、航迹融合技术等组成网上虚拟远程仿真实验系统。以当前目标跟踪、航迹显示、航迹融合等技术为基础,设计并实现辽宁省信息科学技术"虚拟仿真实验教学中心"的建设。本文以开发VTS(Vessel Traffic System)航迹融合网络虚拟仿真教学实验室为目标,分别从网络技术、航迹融合技术、虚拟实验平台技术三个方面进行分析。(1)搭建网络虚拟仿真实验系统,此系统是一个基于C/S结构的局域网远程连接实验平台。采用.NET开发平台,以C#编程语言为编写工具,SQL Server数据库为存储工具。利用TCP/IP通信协议,Socket远程通信接口,开发一套人机交互界面,实现服务器端与多个客户端连接通信的功能。(2)通过分析海上雷达与AIS各个测量参数的优缺点,按照航迹数据预处理、航迹关联、航迹融合的步骤进行航迹仿真,其中对于不同的关联融合算法进行讨论,通过比较各算法的优缺点,给出不同融合算法下航迹融合的综合评价。(3)在Microsoft Visual Studio 2010开发环境下实现系统。完成包括网络连接、数据库存储、雷达与AIS数据处理、采用不同算法进行航迹关联与融合、融合评估等功能设计,并在客户端、服务器端界面显示具体操作结果。
[Abstract]:In order to adapt to the development of the information age, improve the lack of laboratory hardware facilities, limited experimental sites, meet the requirements of higher education resources sharing, open school reform. Virtual simulation laboratory teaching has become a necessary choice of modern experimental teaching reform. Based on computer and network communication technology, a visual network track fusion simulation experiment system is put forward. To understand the application of information fusion technology in the field of maritime target tracking. Learn the process and principle of information fusion between radar and AIS(Automatic Identification system. To deepen the understanding and application of related knowledge, develop a set of simulation system which can realize the simultaneous establishment of communication between multiple client and server, using network communication technology, virtual software technology, database technology. Virtual simulation technology, track fusion technology and other network virtual remote simulation experiment system, based on the current target tracking, track display, track fusion and other technologies. Design and implementation of Liaoning Province Information Science and Technology "Virtual Simulation Experimental Teaching Center". This paper develops VTS(Vessel Traffic system. The virtual simulation teaching laboratory of track fusion network is the target. Respectively from the network technology, track fusion technology, virtual experimental platform technology analysis of three aspects. This system is based on the C / S structure of LAN remote connection experimental platform, using .NET development platform, C # programming language as a programming tool. The SQL Server database is used as storage tool. A set of man-machine interface is developed by using TCP/IP communication protocol and socket remote communication interface. Through analyzing the merits and demerits of each measurement parameter between radar and AIS, we can preprocess the track data and correlate the track according to the track data. The steps of track fusion are simulated, in which different association fusion algorithms are discussed, and the advantages and disadvantages of each algorithm are compared. This paper presents a comprehensive evaluation of track fusion under different fusion algorithms. It implements the system under the Microsoft Visual Studio 2010 development environment, including network connection. Database storage, radar and AIS data processing, different algorithms for track association and fusion, fusion evaluation and other functions are designed, and the concrete operation results are displayed on the interface of client and server.
