基于usb的钢丝绳无损检测数据采集系统设计-微电子学与固体电子学专业论文.docx

华中科技大学硕士学位论文Abstract 华中科技大学硕士学位论文 Abstract Universal serial bus is gradually becoming one of the mainstream interface in the modem data exchange．designed and realized data acquisition system based on USB by the needs of wire ropes non-destructive testing in subject study． In the hardware design，according to the requirement of the wire ropes’s magnetic，we implemented multi-port data acquisition run．ion，using AD7829．In the part of USB interface，we set Up Stream Port and Down Stream Port，sleeting ISPl362．it made the data acquisition card act as either USB HOST or USB DEVICE according to user’s need．In the soft-ware design，we programmed USB firmware and USB driver．USB firmware is design was the most important part．At first，WC introduced the design idea and software layer structure，then we introduced design process of each layer and supported some source code and program flow chart．The firmware adopted fiamework structure，SO it no only had a clear structure，and it Was easy to debug and maintain．When it ran in the system，it could also schedule the submission module which had a hi曲efficiency．In the USB driver design， it introduced the characteristic of the DriverStudio and the design process of the USB driver． Non-destructive testing system based on USB interface Can effectively collect the defect signal of injured wire rope．It send the signal to PC or portable computer for later analyses and filrther process with PC，It Can connect computer memery without PC．The result of test shows that it had some advantage of low power consumption，high accuracy，portability etc，which brought much convenience for non—destructive testing of wire rope． Keywords：data acquisition wire rope NDT USB interface ARM 1I 独创性声明本人声明所呈交的学位论文是我个人在导师的指导下进行的研究工 独创性声明 本人声明所呈交的学位论文是我个人在导师的指导下进行的研究工 作及取得的研究成果。尽我所知，除文中已标明引用的内容外，本论文不 包含任何其他人或集体已经发表或撰写过的研究成果。对本文的研究做出 贡献的个人和集体，均已在文中以明确方式标明。本人完全意识到本声明 的法律结果由本人承担。 学位论文作者签名：吁}学 ／ 溯t年f窍吕日 学位论文版权使用授权书 本学位论文作者完全了解学校有关保留、使用学位论文的规定，即： 学校有权保留并向国家有关部门或机构送交论文的复印件和电子版，允许 论文
