摘要
零位偏差和漂移是所有倾角传感器都待解决的技术难题。本文通过水泡尺旋转180o找平的古老方法深入研究传感器的调平原理,建立一套倾角传感器自动调零的理论和方法。采用步进电机和单片机控制技术设计实现自动调零伺服倾角传感器,很好的解决了零位偏差,时间漂移和温度漂移等问题,使倾角传感器的性能得到提高,具有非常重要的应用价值。
the zero-bias and drift are technical difficulties for all inclinometers. The thesis studies the levelling principle of inclinometers thoroughly and establishes a set of auto-zero theory for inclinometers by the generations-old method to check bubble levels-turning the tool 180° on the measured surface. The inclinometer utilizes step motor and microprocessor control technology to achieve auto-zero, resolving the problems of zero-bias, time drift and temperature drift etc, improving inclinometers＇ performance and having an important application value.
