Aiming at solving the problems existing in the traditional data transmission system of Industrial Computerized Tomography (ICT), which usually uses PCI and ISA bus, resulting in high price, poor scalability, low transmission rate, complex fixing and complex routing, and cannot fulfill the demand for research and production, a set of ICTbased USB 2.0 highspeed data transmission system model is proposed. The system takes a FPGA chip as core logic control module, which controls communications with the USB chipset. The whole hardware designation is described in terms of the performance of reliable data transmission, highspeed and stability. Experimental results show that the proposed method improves the system’〖KG*8〗s stability and reliability. It can satisfy the requirements of ICT transmission .
