摘　　要：鉴于传统的人工周期巡检方式存在诸多弊端,本文设计了一种基于卫星定位的建筑塔机臂尖动态监测模型。以GPS为例建立单历元快速定位模型,给出利用DUFCOM和DC算法相组合的整周模糊度快速确定算法(FARSE)的实现流程;提出了一种基于历元位置偏差的臂尖垂向位移监测参数及预警参数构造方法。初步试验结果表明,利用GPS单历元快速定位模型解算获得了平面精度优于2 cm、高程精度优于4 cm的定位结果;基于该定位结果,从监测参数和预警参数两个角度验证了本文模型设计的有效性。In view of the disadvantages of traditional manual periodic inspection,a dynamic monitoring model for arm-tip of construction tower crane based on satellite positioning is proposed.Taking GPS for example,the single-epoch fast positioning model is built.The flowchart of fast integer ambiguity resolution algorithm based on DUFCOM and DC algorithm is given.And a construction method of monitoring parameters and early-alarm parameters of vertical-deviation for arm-tip based on location-deviation of epoch is proposed.The preliminary experimental results show that the horizontal-RMS is better than 2 cm and the vertical-RMS is better than 4 cm via GPS single-epoch fast positioning model.Based on the positioning results,the feasibility and effectiveness of the proposed model are verified from the monitoring parameters and early-alarm parameters.
