摘要: GNSS是塔机精准管控重要传感器之一,基于伪距的米级定位因精度低不适应智能化塔机发展要求,为提高塔机GNSS位置定位精度,本文利用一种基于GNSS载波相位观测值的精密定位方法,提出一种GNSS精准定点放样方法,应用于建筑塔机智能指挥中。设计并开发了一套基于GNSS的塔机吊装作业定点放样辅助系统(GNSS_PLS)。初步试验结果表明:GNSS_PLS系统的智能指挥精度在厘米级水平,本文算法是行之有效的。

Abstract: GNSS is one of important sensors for accurate-control of tower crane. The low-accuracy of m-level positioning based on pseudo-range is not meeting the development requirements of intelligent tower crane. In order to improve the positioning accuracy of tower crane via GNSS techniques, a precise positioning method applied to positioning-point and setting-out based on GNSS carrier phase observation is proposed in this paper. It is applied to intelligent command for construction tower crane, and a set of GNSS-based positioning-point and setting-out system of hoisting operation (short as GNSS_PLS) is designed and developed. The preliminary experimental results show that the accuracy of intelligent command of GNSS_PLS system is in cm-level, which verifies the effectiveness of the algorithm.

Key words: GNSS accurate positioning, positioning-point and setting-out, hoisting operation, intelligent command, construction tower crane
