摘要
针对目前我国针织机械用高速电磁阀的动态响应参数等无法定量测试的现状,设计了一种针织机械用高速电磁阀测试系统,可用于选针电磁阀等高响应速度电磁阀的动态响应特性和电参数的定量测定。基于虚拟仪器的设计思想,系统采用通用计算机、数据采集卡及自制测试平台,运用机器视觉的非接触式测量方法及高速数据采集技术,通过合理的软件设计实现了测量目标。实验结果表明,该系统可有效地测定针织机械用高速电磁阀的动态响应特性和各项电参数。
At present,the dynamic response characteristics of the high-speed solenoid valve for knitting machinery cannot be quantitatively tested.For this reason,a testing system is designed for high-speed solenoid valve of knitting machinery,which can be applied to the quantitative determination of dynamic response characteristics and electrical parameters of high-speed solenoid valve(e.g.solenoid valve for needle selecting).The system,which is designed based on virtual instrument,consists of the general-purpose computer,data acquisition card and customized testing platform.The high-speed data acquisition technology and non-contact measurement method based on machine vision are utilized.Proper software design is also taken into account to guarantee the functionality of the system.Experimental results indicate that the system can effectively measure the dynamic response characteristics and electrical parameters of the high-speed solenoid valve for knitting machinery.
