摘　　要：针对某工厂大型双柱立式车床,基于数据采集卡和LabVIEW软件建立了在线监测滑枕倾斜量的虚拟仪器测量系统,并进行试验。该系统采用高精度电涡流传感器检测偏移距离,并采用滤波、均值和屏蔽等措施,有效克服了现场干扰,保证了测量的准确性。The online measurement system for ram tilt value of a CNC double column vertical lathe was established by visual instrument technology. High-precision eddy current sensor was used to detect the micro-offset of ram, and a PCI card with 16-bits ADC resolution was used to acquire signal. To ensure the measurement accuracy, filtering, shielding and RMS were adopted to overcome the on-site interferences.
