The The Research on the System of Visualized ultrasonic successive measuring thickness for Steel pipes Abstract Usually，in the field of industry manufacturing and people daily life，it is very importance of knowing the precise thickness of parts of an object to ensure production safety．While the current state is no proper measuring instrument efficiently and precisely meet it nationally． The paper presents a visualized ultrasonic successive thickness measuring system for steel pipes，which primarily consisting of a ultrasonic measuring device and a control software．Using it，not only can we probe the wall thickness of kinds of rigid pipe successively and speedily，but also display curves of thickness in multi—graphs and alert when its value exceeds the standard by the computer inspecting system，furthermore，save and check the data． In the paper，the importance and the current state of the steel pipe ultrasonic thickness inspecting are investigated firstly．Following the principle of the ultrasonic thickness measuring is presented detailedly．Lastly，the software and hardware of the system are explored at large，of which the inspecting software consisting of a main program and a virtual device drive program named HY6070．VxD is emphasized． With the help of the system，the online inspection of the steel pipe automatic manufacture can realized easily，resolving the problem of low efficiency and incomplete defects contrary to the conventional thickness measuring means．The effect response of the measuring system from market is very well． Keywords：Steel pipe，Ultrasonic，Successive thickness measurement Multi-graphic computer display，Virtual device drive program 合肥工业大学本论文经答辩委员会全体委员审查，确认符合合肥工业大学 合肥工业大学 本论文经答辩委员会全体委员审查，确认符合合肥工业大学 硕士学位论文质量要求。 答辩委员会签名：(工作单位、职称) 主席：躲．乃滑榔彩带溯．缎投弓卫 委员： 把》煽极fk 刽友技 剐愁拦 缸氧住 导师： 名 片莩 。破‘ 、及彭令J 独创性声明本人声明所呈交的学位论文是本人在导师指导下进行的研究工作及取得的研究成果。据 独创性声明 本人声明所呈交的学位论文是本人在导师指导下进行的研究工作及取得的研究成果。据 我所知，除了文中特别加以标志和致谤}的地方外，论文中不包含其他人已经发表或撰写过 的研究成果，也不包含为获得盒胆至些盍堂 或其他教育机构的学位或证书而使用过的 材料。与
