| Abstract: | To realize the measure of automobile running parameters and the storage of mass acquired data, a new data acquisition system is designed by analyzing the protocol of Universal Serial Bus (USB) in this paper. It uses the embedded USB Host technology as the emphasis of the design, and uses USB movable disk as its memory device. This paper also gives the design principle, circuit structure, special data communication drivers and applied programs. This system implements the efficient data communication in the USB Host controller, the operations of data acquisition and the data transmission in high speed, and it can realize the function of data acquisition, memory, display and inquiry. The system can work efficiently under severe condition, and it also has excellent compatibility and expansibility because of the modularity design. |
