The universal serial bus ( usb ) is specified to be an new industry standard extension to the pc architecture . it was developed by a coalition of pc industry companies . usb is a serial cable bus that supports data exchange between a host computer and a wide range of simultaneously accessible peripherals Usb ( universalserialbus通用串行总线)总线是pc体系中的一套全新的工业标准，是由intel为首的七家公司于1994年11月推出的，专用于低、中速的计算机外设。
It is a fast , bi - directional , isochronous , low - cost , dynamically attachable serial interface that is consistent with the requirements of the pc platform of today and tomorrow [ 1 ] the benefits of usb , such as easy to use , true of plug and play , high performance , and reduced overall system cost , are just a few of the reasons this technology has gone from specification to product development in several years Usb是快速、双向、同步、动态连接且价格低廉的串行接口，可以满足pc机现在和将来发展的需要。 usb作为一种新兴的计算机外设总线标准，从标准的出现到大规模的应用，仅用了短短几年的时间，这一切都得益于它易用、真正的热插拔、高性能和系统造价低廉等优点。
The dissertation have made a pioneer study on moving picture acquirement , straw object extraction and moving object tracing in the heavy clutter situation of imbalance lighting , camera and straw moving simultaneously with several similar moving objects on mass background , and obtained following achievements : 1 . a capturing system for moving pictures is developed , which could capture and save pictures in real time . the special emphasis is on solving the lost frame problem during images transmitting caused by low transmitting speed of peripheral equipments 针对拍摄时摄像机与秸秆同时发生运动、光照不均、秸秆图像背景复杂、凌乱、运动物体多等特点，论文对运动图像采集，秸秆目标提取，目标跟踪问题进行了较深入的研究，并取得了如下成果： 1本文研究了运动图像的采集问题，开发了运动图像采集系统，着重解决了图像传输中由于计算机外设速度跟不上图像采集速度产生的丢帧问题，实现了运动图像的实时采集和保存。
As a new bus standard in computer peripheral hardware , usb is adopted and widely used in virtual instruments for its ease of use , true plug and play , power supply from bus , high transmission speed , etc . the purpose of this project is to design and develop a virtual instrument that can test and display semiconductor transistor output characteristics curve , instead of tradition instrument which has being used in labs by now 而usb总线作为一种新兴的计算机外设总线标准,由于易用、支持热插拔、总线供电、传输速率高等特点,已经在虚拟仪器当中得到采纳与普及。本文介绍了一种实现晶体管特性曲线测量的虚拟测试仪器的设计和制作方案,其可用来取代目前在实验室中使用的老式的晶体管特性图示仪。
As a new interface caters for rapid development of computer peripheral equipment , universal serial bus ( for short usb ) dispels astriction of communication through traditional serial port and parallel port . it is very suitable for real time image data transmission , which requires high speed . this theme describes two - circuit systems , which utilize usb interface to data from a digital image sensor to pc 为了迎合计算机上设的快速发展以及消除计算机外设通过串、并口的通讯的局限性，出现了新的计算机外设接口usb (通用串行总线) ，这种新型接口对于实时的视频传输很适用，本文设计了两套电脑眼基于ez - usb2131q的usb接口系统。
Universal serial bus ( usb ) is new technology about interface in computer application usb has been used widely since the windows operation system supported the usb interface in computer the major goal of usb was to define an external expansion bus which makes adding peripherals to a pc as easy as hooking up a telephone to a wall jack the program ' s driving goals were ease - of - use and low cost these were enabled with an external expansion architecture universal serial bus （ usb ） is one of the most important developments in pc peripheral interconnect technology since the introduction of serial and parallel ports in the early 1980 ' s the benefits of usb ， such as ease of use ， plug and play ， high performance ， and reduced overall system cost ， are just a few of the reasons this technology has gone from specification to product development in less than 2 years 通用串行总线（ usb ）是应用在pc领域中的新型接口技术，自从windons98操作系统全面对usb接口支持后， usb逐渐进入实用阶段。利用usb可以实现较传统方式更有效、更经济、更多扩展的pc外设与pc相连。通用串行总线（ usb ）作为一种新兴的计算机外设总线标准，从标准的出现到大规模的应用，仅用了短短几年的时间，这一切都得益于它易用、真正的热插拔、高性能和系统造价低廉等忧点。
