摘　　要：本文介绍了由电涡流传感器和MCS-51单片机组成的大轴弯曲量监视仪的原理和设计要点。并针对轴弯曲信号及其零点漂移的特征,提出了一种以弯曲量信号的最小值为基准的零漂软件补偿方法。The principle and key design points of an instrument composed of an eddy-current transducer and an MCS-51 microprocessor for monitoring bow of heavy shaft are introduced in this paper. On the basis of the specific properties of the shaft bow signal and the zero drift of the system, a new method called 'zero drift software compensation', which uses the minimum value of the shaft bow signal as the reference, is proposed for the first time.
