摘要
高速磁浮列车定位传感器的标定需要确定传感器输出电压对应水平位移和垂直间隙2个变量的二维表,数据量大。介绍了一种采用RS—485接口传输信号的标定工具,叙述了计算机控制下步进电机带动标定台二自由度移动的自动标定过程。实验结果证明了该工具的可行性。
2-D sheet of two variables of output voltage vs horizontal displacement and vertical gap needs to be given when a position detection sensor of high speed maglev train is calibrated. A great number of data is involved. A calibration tool with RS-485 interface is presented. The platform of this tool is horizontally and vertically moved by two stepping motors. The calibration can be automatically accomplished under the control of a computer. The experiment result testifies the validity of this calibration tool.
