[Abstract]:With the rapid development of the society and the improvement of people's living standard, the number of motor vehicles is increasing rapidly, and the traffic management problems are becoming more and more serious. Continuing to use the traditional traffic management mode has not been able to meet the requirements of today's traffic management. After fully understanding the development status of traffic management system and mobile terminal equipment at home and abroad and carrying out field investigation, this paper designs a mobile terminal equipment for traffic police road operation. Police officers can query the details of relevant personnel and vehicles and record the illegal information in real time and submit it to the traffic information data center for storage and display as backstage data. Considering the need of practical application, this paper chooses short message as the medium of information transmission. The mobile terminal equipment designed in this paper includes five parts: traffic police information management, driver information management, vehicle information management, information transmission management and other information management. Combined with the requirements of the above system functions, the overall design scheme of the system is given: the traffic management mobile terminal device is based on the ARM11 architecture S3C6410 processor, and uses embedded Linux-2.6.38 as the operating system. The QT, wireless transmission module of Trolltech company is used in the graphic development software and GSM module TC35. is used in the graphic development software. This paper focuses on the key technologies of system data transmission, including short message service, Chinese short message coding and short message security. Aiming at the limitation of traditional Chinese coding conversion algorithm, a coding conversion algorithm is designed, which can save storage space and improve query speed. The idea of this algorithm is to generate storage table and index table and combine dichotomy to realize the conversion between Unicode coding and GB2312 coding. In view of the shortcomings of the mainstream private key encryption algorithm DES and the existing improved DES algorithm, this paper proposes a new DES improved encryption algorithm, which is mainly reflected in the generation of encryption key and the improvement of encryption program, which can effectively improve the intensity of encryption. Ensure the security of information transmission process. In the process of design and implementation of mobile terminal devices, this paper first constructs the embedded Linux cross-compile and development environment, then customizes the embedded Linux operating system, including the production of Bootloader kernel and file system configuration and transplantation; After the hardware and software platform is built, the design of serial port, touch screen driver and application program is emphasized. According to the functional requirements of the traffic management system, the contents and forms of the data stored in the traffic information data center are given, and the list of the traffic database is designed in detail, in which the driver information table and the vehicle information table list are given. Finally, the QT development platform is built to realize the design and development of the GUI interface of mobile terminal equipment. Then, the system running and testing are carried out, and the schematic diagram of some interfaces of mobile terminal equipment is given. The results show that the terminal can send and receive short message safely and encode and decode correctly.
