【摘要】 智能交通系统ITS(Intelligent Transport System)的应用和发展已迫在眉睫,作为交通领域的重要科技项目,是解决城市交通运输、车辆监管、环境污染等问题的综合管理控制体系,近年来,嵌入式车载导航监控系统EVNCS(Embedded Vehicle NavigationControl System)成为ITS应用研究的主要课题之一,并且是整个ITS体系结构框架的前提环节和核心技术。在此背景下,本文根据目前我国实际道路状况,分析国外市场导航与监控合而为一的车载应用产品发展走向,设计了一个整合GPS定位导航监控,基于嵌入式Windows CE系统平台,实现GPRS通信数据传输和导航地图显示功能的车载应用系统。本课题是ARM9 & Windows CE 5.0操作系统的嵌入式交叉开发过程,硬件部分的设计,以嵌入式目标板上ARM2410核心板为主,采用ARM9处理器S3C2410芯片作为主控MCU,RS-232串口分别连接GPS模块和GPRS模块,ARM2410控制着LCD液晶屏,显示脱机运行的导航地图和通信监控界面。软件部分,以构建的Windows CE 5.0/EVC4.0交叉编译环境为平台,设计了GPS定位信息提取的软件流程,利用EVC工具下MFC工程模板开发了GPRS通信功能图形界面,鼠标点击即可实现数据传输;利用EVC提供的基本绘图函数,结合本校园地理环境,开发了特制的袖珍型北方工大校园导航地图,避免专业电子地图二次开发带来的体积冗繁和成本高等困扰,能基本定位准确,完成导航需求。本文提出设计的EVNCS应用系统,充分利用WinCE平台体积小、可裁减的资源特性,设计了可视化程度高、易于操作的图形功能界面,整合了丰富的应用功能,并且按需特制袖珍型导航地图,与论文后续给出的Linux系统平台上相同功能完成的情况作横向对比,结果分析鲜明,验证了本文设计的车载应用系统具有十分良好的用户体验效果。
【Abstract】 Intelligent Transport System that the application and development have already a necessary trend, which is the integrated supervise control system, qua the most important technology item about traffic domain. Recently, Embedded Vehicle Navigation Control System, EVNCS becomes the main point, and is a precondition tache, a kenel technology. In this case, according to our country’s roadway status, found on the vehicle application product trend that integrated navigation and control system, this paper designs a embedded vehicle GPS system with navigation and control applications, based on Windows CE platform, then realizes that GPRS communication data transport and navigation map display.This paper mainly introduces the embedded across device course with AM9 & WinCE 5.0. The hardware partment, ARM2410 is the key of embedded target board, S3C2410 chip as the core MCU, RS-232 serial link GPS module and GPRS module, ARM2410 command LCD screen which shows offline function running outcome. The software partment, on the fabricative across compile environment platform of WinCE 5.0 / EVC 4.0, designs the soft-folw about GPS orientation information receiving; devises GPRS communication functionial graphical interfaces using EVC / MFC project template, that mouse action can be carry out communication transmission; besides, EVC supplys basice plot funtions, devises tailor-made pocket navigation map on North China University of technology campus geography circumstance, which can be carry out orientation and navigation, the spark point is that these plans avoid the heavy and complicated and cost high etc. problems with special electron-map secondly device.In this EVNCS system, takes full advantage of the smaller bulk and tailorable feature of WinCE platform, achieves functional graphical interfaces apt operation, and abundant application functions, also pocket navigation map. Compare function achievements on WinCE platform with the ons on Linux platform, the obvious endings verify that the paper designs have nicer effect: all-around functions for users, friendly operation condition for users.
