摘　　要：为解决传统的工业CT数据传输系统通常采用ISA和PCI总线,存在着价格昂贵、可扩展性差、传输速度低、安装不方便和布线复杂,在某些场合已不能满足科研和生产的实际需求等问题。提出了一套基于USB2.0工业CT的的高速数据传输系统模型,该系统采用FPGA芯片作为系统的核心,控制与USB接口芯片进行数据交换。同时,从数据传输可靠、高速、稳定的性能出发提出了整体硬件设计方案。实验结果表明,该方法提高了系统数据传输的稳定性,可靠性。满足实际工业CT传输需要。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＇s stability and reliability. It can satisfy the requirements of ICT transmission .
