| Recently, with the continuous progress of society, people’s living standards for the continuous improvement of the car for people is already a necessity. It is convenient for people to travel, but also has a very difficult problem.with the improvement in the number of motor vehicles, urban development has not kept up with the speed of its development, the urban traffic congestion, air quality is severely reduced and other problems have cropped up. This topic research is intended to better solve the above problems, the design of the Android car navigation and traffic interactive terminal based on, into two parts: the Server and the Client, combined with the embedded system hardware design, with the vehicle navigation and to collect real-time traffic information, road condition information independently and accurately upload and traffic information query function, so that the terminal can be applied in actual life.The design of embedded processor, Android system, wireless network transmission technology and C-S system framework together. The design and implementation of the Android system of vehicle terminal, can communicate with a remote Server, real-time acquisition of urban traffic information and complete information interaction, so as to realize the urban traffic conditions in the collection and dissemination. The vehicle terminal not only has the basic function of vehicle, can we build traffic information exchange mechanism, the user not only can upload their own location of the traffic information can query each mark point traffic information, advance the traffic conditions of the city make a pre judgment.The design of hardware by high performance, with powerful processing ability of S3C6410 ARM11 chip as the core processor Feiling company ok6410 plate as the hardware platform, programming the Android operating system, at the same time in the system development phase the original road N70 tablet for the development of test plate, support to start NAND flash and NOR Flash, the internal configuration of GPS module, CMOS camera module, wireless network card module, touch screen;Software part is mainly based on the 4.2.2 Android operating system as the core, based on Java programming. Also, remote Server module uses a two implementation schemes, the first scheme is to Tomcat+My SQL. By setting up a local Server using Tomcat and My SQL software loading for users to upload traffic information collecting and sorting, and for users to download traffic information to provide services. Second programs to call the third party mobile application back-end software Bmob, by calling the Bmob to provide the data interface, to achieve data upload and finishing, traffic information download, complete one-stop solution.The focus of the work of this paper is achieve Android car navigation and traffic information function and remote Server module information storage and sorting and information is available to download on, after a long time of study and discussion, successful solves the one of the difficult problems, and a detailed description of the, by running and debugging, to achieve stable operation between the terminal and the Server, traffic information upload to achieve fast, high precision, low error rate, reliable data and information, according to the final test, the successful completion of a plurality of functional modules to design requirements. |
