摘　　要：由于现有的电子水平仪随时间、温度的变化会产生零点漂移,测量前需进行手动调零。根据水平尺旋转180°找平的古老方法设计出带有自动消除零点漂移的智能型电子水平仪,介绍了带自校准功能的电子水平仪的硬件框图、软件设计和实验分析。实验结果表明:该方法能够大幅提高仪器测量精度。Change of time and temperature will bring zero shift to electronic gradienter nowadays. Manual regulation is necessary. An intelligence electronic gradienter is presented which can automatically dispel the zero shift. Its design concept is based on the ancient method that the level can find horizon by revolving 180°. The hardware design, software design and experiment analysis are introduced. The experimental result indicates that the method can largely improve the measuring accuracy of the gradienter.
