According to the demand of BOTDA optical fibre sensor for real-time application, a high-speed data acquisition system with graphical operation interface is designed by using FPGA and USB. In this paper, hardware architecture and logic design are carried out for data acquisition with FPGA as the control device, and the upper computer with functions of data display and graphic demonstration is designed by using C# language on the PC terminal. Finally, joint debugging is carried out for the lower computer and the upper computer, and the experimental results show that the high-speed data acquisition and transmission functions are successfully realized, which meets the design requirements of the data acquisition system in BOTDA optical fibre sensor.
