基于WebGIS的车辆监控系统研究与实现
摘要
随着全球城市的不断发展,日益严重的交通问题备受关注。作为智能运输系统的关键——车辆监控系统近年来得到了迅速的发展。本文通过WebGIS的车辆监控系统的研究与设计,为用户提供基于Internet/移动终端的车辆监控的多功能软件平台,实现对车辆信息的查询、分析、处理与控制。
本文首先研究了基于WebGIS车辆监控系统的框架,并从系统的研究体系、架构设计、模块抽象化、功能模块方面展开研究。
针对系统中的数据流问题,论文从通讯、处理、存储多个角度进行研究。给出了基于B/S模式的网站应用、Servlet服务链机制、GPRS的无线网路通讯的数据传输处理机制的实现,重点研究了如何保证数据传输的高效、稳定和实时性,设计了数据库并引入优化技术,在降低系统开发难度的同时保证了系统的实时性和信息完备性。
为了提供高质量WebGIS和车辆监控服务,本文提出利用JavaScript语言将移动车辆运动轨迹的描绘从服务器转移到客户端来完成的思想,有针对性地解决车辆监控中Web页面闪烁的问题;同时研究设计MapJ缓存对象池、Web页面局部刷新和部分情况下浏览器完全处理GIS图像等三种方法,大幅提高WebGIS车辆监控的效率。
本文最后针对移动终端空间制图服务,以实现一套基于Java手机的车辆监控软件为目的,以空间移动GIS制图为核心研究内容,在移动终端上对WebGIS的车辆监控进行扩展研究。
With continuous advancement of global cities’modernization, more and more attention is paid to the increasing traffic problems. Vehicle monitor and control system is the core part of the ITS, the aim of this thesis is to realize a vehicle monitering and controlling system based on WebGIS. The system will provide the users a software based on Internet/mobile terminal whicle which could make the users query, analyse, manage and control vechicles.
Firstly the framework of vehicle monitering and controlling system based on WebGIS is discussed, and then study system, architecture design, module abstract and function module design are researched.
Then,the data of the system is researched on communication, treatment and storage area. The method of data handling and transmission based on B/S model Web applications, servlet service chain and GPRS wireless communications is given.and the database is designed and data optimization technology was used. These assure the real-time capability and information self-contained capability of the system while the difficulty of system development is reduced.
In order to provide high-quality vehicle monitoring service based on WebGIS,the vehicle trace is described only in client without server used JavaScript, and this technology solved the problem of the flashing Web while monitering vehicle.At the same time,in order to substantially increase the efficiency of vehicle monitoring base on WebGIS, MapJ pool, some of the page refresh and GIS browser completely process image are researched.
At last, space map service of mobile phone expansion webgis is researched at the core content of mobile GIS map service in order to give a vehicle monitering software on Java mobile phone.
