摘要 该文文旨在利用磁悬浮技术,实现对轻量物件的较高精度称重,并通过对原理及应用做了详尽的阐述和实验,设计了一个吸式的磁悬浮式电子秤。该文涵盖磁悬浮电秤系统的设计方案,电磁线圈非线性、系统的电磁力模型、系统的控制模型及控制电路的设计与调试。解决了磁悬浮电子秤设计的几个难点:电磁场的非线性问题、各种材料和部件的选取和机械加工及控制电路的设计与参数调试。该文的创新点有:(1)采用红外收发二极管设计系统的距离传感器,同时也使用摄像头作为传感装置进行试验;(2)创新图像化反馈,采用NI模块配合Lab VIEW进行图像化处理;(3)自行绕制电磁线圈,采用最佳1j-50软磁镍铁合金作为铁芯。 The paper aims to construct a device, using the tech of maglev, to weigh things and behave artistically. Design an adsorption of magnetic electronic scale, which is based on the related electronic scale design researches. The paper introduces the system structure of the magnetic electronic scale and implementation methods, and focuses on the non-linear feature of the electromagnetic coil, electromagnetic force system model and the control model. During the design we solved several difficulties: the nonlinear feature of the electromagnetic field, the mathematical model of the system, the selection of various materials and components in machine, and the design of control circuit and debug parameters. There are several innovations: First, we use infrared sensor and also try camera as the sensor;second, we use image as feedback, cooperating with NI and Labview; third, we construct our coil with 1j-50 Fe-Ni soft magnetic alloy.
