基于USB数据同步采集设计方案

Synchonous Acquisition Design Based on USB

介绍了USB在数据同步传输方面的可行性及其在同步传输方面的优点,合理解决了数据采集的同步性问题.和以往的采集方法相比,具有高速、高精度、多路同步采集及实时处理等特点,可广泛地应用于工业等各方面的数据测试系统中.

The feasibility about synchronous transmission of data with USB(Universal Serial Bus) is introduced and the virtues of this transmission mode are noticed too. By comparing with the other ways of data acquisition, the way introduced here is not only convenient and high speed, but also reasonably solves the synchronous question of data acquisition. Besides, the way also has characteristics of high speed、 high precision、 multi-route acquisition、 real-time processing, and so on, so it can be applied to testing system of many aspects. Through the study of USB, four feasible ideas are brought forward.
