Embedded Automotive Monitoring Terminal Design And Implementation

With the progress of the society and the improvement of the economy, the quantity of vehicles increase rapidly.But the development of the road fall behind. As a result, the accidents happen frequently, which cause large losses for the country and people.In order to solve such problem of traffic, the research and exploitation of the vehicle monitoring system which can realize the function such as all-weather fixed position, navigation for the vehicle is attended especially.The embedded vehicle monitoring terminal is the important part of the vehicle monitoring system. In this thesis, the concept of embedded system is applied to the vehicle monitoring system. The thesis advanced a solution to the vehicle monitoring terminal based on real-time operating system uC/OS-II.At first ,the constitution, function and the key technology of the vehicle system was analyzed. And then the hardware design and realization of the embedded vehicle monitoring terminal was introduced. After that,the replant of operating system and the design of the hardware drive was realized. At last, the application protocol and application software was completed. The experimental results have shown that the embedded vehicle monitoring terminal has high precision and real time operation and the embedded vehicle monitoring terminal has realized the function, such as fixed position, control for the vehicle, communication with the monitoring center and so on perfectly.
