摘　　要：为保证电子提花机电磁阀组件在自动织造系统中的可靠动作,减少其对织物产生的轨迹误差,设计了一种对电磁阀组件工作状态检测的涡流阵列传感器。通过理论计算和组件结构确定检测线圈的相关参数,采用多路复用开关对阵列信号提取;在Ansoft Maxwell电磁场仿真中建立传感器检测模型,求解电磁阀组件在两个工作状态下的电感变化;考虑通丝张紧产生的微位移,仿真分析通丝位移1~10 mm的对传感器输出变化的影响,并进行实验验证仿真结果的正确性。结果表明,传感器产生的489 nH的电感变化可以反应出电磁阀组件的工作状态,验证了检测方法的正确性,且最大误差不超过2.559%,能为提花机控制系统提供可靠的反馈数据。In order to ensure the reliable action of the electromagnetic valve assembly of the electronic jacquard machine in the automatic weaving system and reduce the trajectory error caused to the fabric,an eddy current array sensor for detecting the working state of the electromagnetic valve assembly is designed.Determine the relevant parameters of the detection coil through theoretical calculation and component structure,and use multiplexing switches to extract the array signal.A sensor detection model is established in Ansoft Maxwell electromagnetic field simulation to calculate the inductance change of the solenoid valve assembly under two working states.Considering the influence of the micro-displacement caused by the tension of the wire,the output changes of the sensor with the wire displacement of 1~10 mm are simulated and calculated,and experiments are carried out to verify the correctness of the simulation results.The results show that the inductance change of 489 nH generated by the sensor can reflect the working state of the solenoid valve assembly,which verifies the correctness of the detection method,and the maximum error does not exceed 2.559%,which can provide reliable feedback data for the control system of the jacquard machine.
