目前,光学经纬仪、电子经纬仪在使用现场自校的方法是找一目标,进行简单竖盘指标差核验,市场上也没有自校的检测工具,在实验室检定时一般采用经纬仪检定装置来完成。检定目前有两种方法:一类是多目标法;另一类是采用平行光管和多齿分度台方法。上述两种方法只能在实验室进行,在现场检测校准中不能使用。一、自校检测板的设计本设计的目的是提供一种体积小、结构简单、操作方便、便于携带、可用于现场检测校准的经纬仪自校检测板。
Currently, optical theodolites and electronic theodolites use a method of on-site self-calibration to find a target for simple vertical disk index difference verification. There is no self-calibration testing tool on the market. When the laboratory tests are performed, a theodolite verification device is generally used. There are currently two methods of verification: one is multi-objective method; the other is the use of collimator and multi-tooth indexing table method. The above two methods can only be carried out in the laboratory, can not be used in the field test and calibration. A self-test board design The purpose of this design is to provide a small size, simple structure, easy operation, easy to carry, can be used for on-site testing and calibration of theodolite self-test board.
