摘要
鉴于传统的经纬仪测量方法检测建筑塔机侧向垂直度存在诸多弊端,提出一种基于全球卫星导航系统(Global Navigation Satellite System,GNSS)的建筑塔机侧向垂直度智能检测技术。基于GNSS的动态检测模型,以GPS系统双频数据为例,给出单历元快速模糊度解算算法(Fast Ambiguity Resolution for Single Epoch scheme,FARSE)流程,设计一种建筑塔机侧向垂直度智能检测方法,并基于Visual Studio 2017平台,利用C#编程语言,设计并开发一种基于GNSS的建筑塔机侧向垂直度智能检测云端系统(GNSS_LPDS)。初步实验结果表明:GNSS_LPDS系统总体设计是行之有效的,系统智能检测平面精度优于2 cm、高程精度优于3 cm,验证了本文算法的正确性。文中算法可为建筑塔机抗倾翻稳定性智能检测提供一种高精度智能化解决方案。
Regarding the disadvantages of traditional theodolite surveying method applied to lateral perpendicularity detection for construction tower crane,the GNSS-based lateral perpendicularity intelligent detection techniques for construction tower crane is proposed.And then,the GNSS-based lateral perpendicularity intelligent detection method for construction tower crane is designed based on GNSS dynamic detection model,and the flowchart of FARSE algorithm is given based on GPS dual-frequency data,and the GNSS-based lateral perpendicularity intelligent detection cloud system(GNSS_LPDS)is designed and developed based on Visual Studio 2017 platform using C#program language.The preliminary experimental results show that the accuracy of intelligent detection of GNSS_LPDS system is better than 2 cm in horizontal direction and 3 cm in vertical direction,verifying the effectiveness of proposed algorithm in developed system.The high-precision intelligent solution can be provided for intelligent detection of anti-toppling stability for construction tower crane.
