Design Of The Browser About Traffic Situation Based On3G Communication

Design of the browser about traffic situation based on3G communicationAfter recent years of development, the cause of traffic management in China has made substantial progress. However, the development of urban transport has exceeded the speed of development of traffic management in China because of sustainable development of urbanizat-ion traffic and rapid increase in car ownership.The development of China’s urban is different, transport Traffic situation is complex,and it is very difficult to manage.In order to the situation of many traffic junctions and traffic flow in China’s large and medium-sized cities, a intelligent transportation system based on3G communication technologies play a significant role to regulate traffic flow in the intelligent,and the core of the intelligent transportation system is:each driver in driving process can real-time understand a area traffic fort current situation,then they can adjustment his driving process according to the actual situation, thus reach the result that everyone is "commander".This paper task is to design the browser which is used in the intelligent transportation system of monitoring the traffic,and the main target is through the design of embedded terminals we can browse the pages of the monitoring front-end anywhere.And if each driver can understand a area of each traffic fort traffic through this topic design of the traffic in the browser,and this goal will require the browser having area traffic map to simple browsing, the3G network support, touch screen operation support, small memory sliding,and quick speed.The main content of this paper is:build the hardware platform based on ARM processor S3C2440and the corresponding software platform. According to the characteristic that hardware and software can be cut in embedded system application, give the needs and the overall program of the browser design of the traffic situation of the3G communications; cut and transplant the u-boot in the layer of system boot;cut and transplant the linux system in the operating system layer;cut and transplant Ot/Embedded in the graphical user interface layer; in embedded Linux systems3G network communication is supported transplant and use usbmodeswitch tool, write the dial-up script and achieve3G dial-up in the development board.The focus of the paper is that the specific design of the Qt/Embedded browser,first Qt GraphicsView architecture and QtWebKit module are studied,and then using Qt GraphicsView architecture to design Embedded traffic map interface,and use QtWebKit module to design Embedded web browser,and use Qt layout drawing function,design a complete Embedded browser.Finally,do a little change to the function of the QtWebKit engine according to characteristics about this browser using in this Intelligent Transportation System.Finally run the browser in the hardware platform, and mainly do the test about the web browser function and performance:The test results show that this design achieves the basic functionality of browsing the web,most of the relevant agreement,supports form slide viewing capability,memory normal operation is1.5-3M,the time of visitisng the website is2-3S,and is able to meet the basic requirement for using in the intelligent transportation system.
