摘要

With the rapid development of welding technology,it is more and more important for the detection of its welding process.As is known to all,besides welding power source,automatic and semi-automatic welding qualities are also affected by the reliability and stability of wire-feeding system directly.The design of speed measurement based Hall speed sensor has realized the real-time display and storage of wire-feeding speed.Analyzed the principle of speed measurement,use the Hall sensor which has the fast response and high measurement precision,combineding with the SCM circuit,a new speed measurement system was designed.Therefore,this study designs a upper computer software based on LabVIEW.The system has the advantages of low cost,high reliability,fast speed and wide measuring range.%随着焊接技术的迅猛发展,对于其焊接过程的检测也越来越重要.除焊接电源外,自动及半自动焊的焊接质量也受送丝系统的可靠性和稳定性的直接影响.采用霍尔转速传感器开发的焊接送丝速度检测系统,通过分析转速测量原理,利用霍尔传感器响应速度快和测量精度高的特性,结合单片机运算电路设计了一种新型的转速测量系统,并基于Labview开发环境设计出一款上位机软件,实现了送丝速度的实时显示和数据的存储分析.该系统具有成本低、测量精度高、速度快、测速范围大等优点.
