一种高精度定日镜基准位置定位检测方法及装置
摘要：
本发明公开了一种高精度定日镜基准位置定位检测方法及装置，通过对霍尔开关磁滞性进行修正以确定定日镜的初始基准位置，以修正霍尔开关磁滞性造成的定日镜基准位置定位偏差，包括步骤：S100：霍尔开关沿第一转动方向转动时，采集霍尔开关信号线电平第一次发生跳变的第一位置；S101：霍尔开关沿第二转动方向转动时，采集霍尔开关信号线电平第一次发生跳变的第三位置；S103：基于所述第一位置和第三位置确定定日镜的初始基准位置。本发明可以修正霍尔开关磁滞性造成的定日镜基准位置定位偏差，提高定日镜基准位置定位精度。
摘要（英）：

The invention discloses a high-precision heliostat reference position locating and detecting method and device. The initial reference position of a heliostat is determined by modifying the hysteresisof a Hall switch, and the locating deviation, caused by the hysteresis of the Hall switch, of the reference position of the heliostat is modified. The method includes the steps of S100, collecting thefirst position where primary hopping happens to the level of a signal line of the Hall switch when the Hall switch rotates in the first rotation direction; S101, collecting the third position where primary hopping happens to the level of the signal line of the Hall switch when the Hall switch rotates in the second rotation direction; S103, determining the initial reference position of the heliostat on the basis of the first position and the third position. The locating deviation, caused by the hysteresis of the Hall switch, of the reference position of the heliostat is modified, and the locating precision of the reference position of the heliostat is improved.
