【摘要】 为解决在分布式数据采集系统中如何实现大量数据传输存储的问题,文章讨论了一种方案———嵌入式USB-Host大容量数据存储方案,对比传统的串口数据传输,提高了传输速度,且脱离了PC机的限制。具体阐述了该方案的硬件组成和软件实现,有较高的参考价值。该方案已经纳入分布式可控震源数据采集系统的构建方案,并通过了模块功能测试,验证了该方案的可行性与优越性。更多还原

【Abstract】 In distributed data acquisition system, in order to realize high-capacity storage of data , the embedded USB-Host scheme is proposed. Compared with traditional serial data transmission scheme, the scheme shake off many problems of wire communication. And the embedded USB-Host allows direct communication between data acquisition system and USB storage device. With it,the storage capacitance is raised greatly than usual. The hardware structure and software realization are presented. This scheme has been applied to the Distributed Seismology Data Acquisition System.更多还原
