全站仪机械轴系误差的影响及调校方法

Influence of system errors from total station mechanical axis and its adjustment method

全站仪是测量工程常用的仪器之一,为了消减全站仪机械轴系误差对测量精度的影响,用户需要定期送检预使用的全站仪,通过检定、校准的方法得到相应的改正数。本文探讨了全站仪轴系误差的消减方法,在施工过程中,用户可以利用全站仪的配套设备,结合有利地形,利用该方法对一部分轴系误差项进行现场调校,以提高仪器的观测精度。

Total station is one of the instruments commonly used in surveying engineering.In order to reduce the influence of mechanical axis system errors of total station on measurement accuracy,users need to send the pre used total station regularly for verification and calibration,and obtain corresponding corrections.This poper explores the method of reducing the mechanical axis system errors of the total station,and in the construction process,users can use the supporting equipment of the total station and method,combined with the favorable terrain,to adjust some mechanical axis system errors on the site,so as to improve the observation accuracy of the instrument.
