中文摘要：

针对利用经纬仪测量塔机垂直度精度不高、不能实时监测等问题,提出一种塔机垂直度自动测量方法。通过测量塔机转角自动判断臂架位置,进而确定垂直度测量面。分析了现行垂直度测量的误差原因,推导了垂直度与塔机转角和倾角之间的计算公式,并设计了塔机垂直度自动监测系统。

英文摘要：

There exist some problems when using theodolite to measure tower crane verticality,such as low accuracy,manual operation and so on. The paper proposes an automatic measurement method for tower crane verticality. The method estimates the position of the tower crane boom automatically by measuring the angle of inclination and then determines the vertical measurement surface. Firstly,the measurement error of using theodolite for tower crane verticality is analyzed,and then the formulas of tower crane verticality are derived. Finally,the automatic measurement and monitoring system for tower crane verticality is designed.
