在工业生产及日常生活中,往往需要知道物体各处的精确壁厚,以确保生产安全。目前国内缺乏高效、精密的测量工具。 文章介绍了一个由超声波测厚系统装置和本论文设计的监控软件组成的“钢管可视化超声波连续测厚系统”,其不但能对各种刚性管材各处的壁厚进行高速、连续地探测,还能通过计算机检测系统多图形地显示壁厚曲线、超标报警,并能进行数据存储和查询。 文章首先研究了超声波测厚的国内外发展现状及研究意义,然后介绍了超声测厚的原理,最后详细说明了钢管超声波连续测厚系统的软硬件组成,其中重点介绍了由超声连续测厚主程序和虚拟设备驱动程序HY6070.VxD组成的监测软件。 此测厚系统能实现钢管自动化在线检测,解决了传统测厚方法效率低、检测不完全的缺点,用于市场后反应良好。
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.
