【摘要】 USB是近年来在计算机领域日益流行的一种总线形式。由于它的诸多优点,有关USB在各方面应用的研究正在不断开展。在数据采集领域,基于USB的数据采集装置不但具有速度快,容易扩展等特点,而且由于即插即用的功能,使它能适合更广泛的应用场合。 本文首先回顾了以往不同型式的数据采集系统,然后在扼要地介绍了USB1.1原理的基础上,提出了一种基于USB的数据采集控制系统的总体方案。本文在第三章详细介绍了硬件电路的设计;在第四章详细介绍了软件的设计,该软件包括固件程序、驱动程序和应用程序三大部分,每个部分都给出了详细的开发步骤。本文在第五章具体论述了该方案在生物信号分析处理系统的具体应用,这既是本课题开发的USB数据采集系统应用的一个例子,也是本课题所承担的任务。更多还原

【Abstract】 USB is a type of computer bus which increasingly prevails in recent years. With USB having many advantages ,the research of application about USB in many fields is developing. In the field of data acquisition, data acquisition devices based on USB not only have the advantage of speed on data acquisition, being conveniently expanded,but also are able to be applied to more broad fields with PNP function.The paper firstly reviews different types of data acquisition system, then after brief introduction of USB 1.1 protocol, a set of design scheme of data acquisition and control system based on USB is put forward. In the third chapter, the hardware design is detailedly introduced and in the fourth chaper, the software design is detailedly introduced,which includes three parts, fireware software design,USB device driver design and PC application design, each part includes detailed steps of development .In the fifth charpter,the article detailedly discuss how the scheme is applied in biologic signal collection and process system ,which is a applied example of data acquisition and control system based on USB by the subject group and is also a part of task assumed by the subject group.更多还原
