The Research And Realization Of The Data Processing System Of Vehicle Airmanship Terminal

At present vehicle airmanship has become one of the most active fields in the research of embedded system. In order to meet the requirement of intellectual traffic, one vehicle navigation terminal data processing system is researched, and it is implemented in the thesis.The thesis introduces the background, the present situation and the real-life significance of the intellectual traffic system and vehicle airmanship system. Then, the related technology of the airmanship is presented. One design scheme of software and hardware on the basis of deep analysis of vehicle airmanship and data processing technology theory is proposed which is based on the embedded system. What's more, the detail whole structure software design of some parts of the data processing system is also described. After the complete consideration of the performance, development expense and R&D cycle etc, we partition the module reasonably and introduce the structure and function of each module in detail. The thesis emphasizes on introducing the design and realization process of the subsystem of traffic data storage. The thesis particularly describes the idea and method of the process from data classification, data definition to data storage.The system supports real-time data collection, the classification storage of different kinds of data, and the processing of real-time data. The system designs different data-base storage mode respectively in order to storage the data according to the data character of the electronic map and real-time data, which both satisfies the requirements of data storage and improves the whole performance of the system.
