摘　　要：介绍了一种基于USB 2.0总线的接口转换系统,主要运用于航天设备的地面检测中。讨论了USB 2.0控制器CY7C68013A与FPGA构成接口转换系统的方式以及系统的通用性,着重论述了通用接口设计中的注意事项以及影响USB 2.0设备速度的因素。应用结果表明,USB 2.0转换的接口有很强的通用性,能达到很高的传输速率,可以广泛地运用于航天设备地面检测以及普通工业测试系统中。An interface transition system based on USB 2.0 bus is introduced, which is mainly used in the ground testing of space equipment. The method of using USB 2.0 controller CYTC68013A and FPGA to construct the interface transition system as well as the system＇s feasibility are discussed. The factors of influencing the speed of USB 2.0 and the key points of general interface design are discussed. The results prove that this system can reach very high transmission speed, and thus it can be widely applied to the ground-testing of space equipment and testing of industrial systems.
