[Abstract]:Intelligent Transportation system (its) is an important measure to solve urban traffic congestion and optimize traffic environment. Intelligent bus system is an important part of intelligent transportation system. The establishment of intelligent public transport system can effectively improve the efficiency and service level of public transport, thus providing a more high-quality and convenient transportation service for the general public travel. As an important vehicle terminal equipment, intelligent vehicle voice announcer plays an important role in the development of intelligent bus system. On the basis of reading a lot of references and related technical manuals, this paper puts forward the design scheme of intelligent vehicle voice announcer by using embedded technology such as GPS and wince, and realizes the basic function of intelligent vehicle voice announcer. As an important part of the intelligent bus system, the intelligent vehicle voice announcer is responsible for the functions of GPS data acquisition, vehicle real-time positioning, intelligent cruise voice reporting and updating the on-board LED display as the terminal of the system. In this paper, the design and implementation of the intelligent vehicle voice transmitter are introduced in detail, and the selection of the system hardware platform and the software platform is put forward in the overall scheme, and the specific chip selection and circuit design of each module are introduced in detail in the hardware design. In the software design, the customized transplantation of the operating system and the specific design of the application program are elaborated in detail. Finally, with the rapid development of the intelligent public transportation system, the requirement of GPS positioning accuracy will be higher and higher. In this paper, the theory of GPS high precision dynamic location is studied, and several popular high precision dynamic positioning algorithms are analyzed. It is known that the fast and reliable solution of integer ambiguity is one of the key problems to be solved to realize GPS high precision dynamic positioning. In this paper, a fast algorithm for solving GPS integer ambiguity with constraints is studied. The simulation results show that the algorithm achieves a certain balance between the ambiguity resolution efficiency and reliability, and is suitable for dynamic positioning theoretically. After the design of the intelligent vehicle voice announcer was completed, it was tested and modified and optimized. Through testing, the terminal system has completed the vehicle real-time positioning, intelligent voice broadcast LED update display function.
