| Abstract: | In order to transmit the sampled data of the wheel tread abrade to the PC terminal,the data transmission system based on USB technology is designed in this article.The timing of the sampled data stream is controlled by FPGA which communicates with the PC terminal with the help of USB2.0 interface chip CY7C68013.In this article,the hardware structure of data transmission system,the software design,the working flow and firmware of the USB interface chip are systematically discussed.Compared to the traditional PCI bus transmitting system,this system is designed to support plug and play technology,thus it can be widely used in the portable detection for the wheel tread. |
