【摘要】：智能交通系統(tǒng)是解決當今城市交通擁堵，優(yōu)化交通環(huán)境的重要舉措。智能公交系統(tǒng)是智能交通系統(tǒng)的重要組成部分。智能公交系統(tǒng)的建立可以有效的提高公交運行效率和服務水平，從而為廣大市民出行提供更為優(yōu)質、便利的運輸服務。而智能車載語音播報器作為重要的車載終端設備在智能公交系統(tǒng)的發(fā)展中占有重要的地位。 本文在閱讀大量的參考文獻和相關技術手冊的基礎上，運用嵌入式技術、GPS技術、WinCE等，提出了智能車載語音播報器的設計方案，并實現了智能車載語音播報器基本功能。 智能車載語音播報器是智能公交系統(tǒng)的重要組成部分，作為系統(tǒng)終端其承擔著GPS數據采集、車輛實時定位、智能巡航語音報站以及更新車載LED顯示等功能。本文詳細介紹了智能車載語音播報器的設計與實現，在總體方案中提出了系統(tǒng)硬件平臺和軟件平臺的選擇；硬件設計中對各模塊具體芯片選型及電路設計進行了詳細介紹；在軟件設計中對操作系統(tǒng)的定制移植及應用程序具體設計詳細進行了闡述；最后，考慮到隨著智能公交系統(tǒng)的快速發(fā)展，其對GPS定位精度的要求將會越來越高，，本文對GPS高精度動態(tài)定位理論進行了研究，分析當今流行的幾種高精度動態(tài)定位算法可知，整周模糊度的快速、可靠解算是實現GPS高精度動態(tài)定位必須要解決的關鍵問題之一。本文研究附有約束條件的GPS整周模糊度快速解算算法。通過仿真表明，該算法在模糊度解算效率和可靠性中間取得了一定的平衡，理論上適合于動態(tài)定位。 智能車載語音播報器設計完成后，通過上車實際測試并進行了修改和優(yōu)化。通過測試，目前本終端系統(tǒng)已經完成了車輛實時定位、智能語音播報、LED更新顯示功能。
[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.
