摘要
高速度、高可靠性、低功耗的串行系统总线是航天通信领域进一步发展必须解决的一个关键问题。简要地介绍了USB 2.0通信协议的基本原理、系统结构和数据传输,并以此为基础给出具有高可靠性的USB通信系统框架结构。并在此基础上提出具体的方案,经试验此USB设备接口可满足通信的性能要求。
The serial system bus with the high speed, high reliability and the low power dissipation is one of the key problems that must be solved for the further development of the spaceflight communication domain. The basic principle, system structure and data transmission of the USB2.0 are put forward. It proposes a scheme, the USB interface can satisfy capacity of communication by experiment.
