预制构件吊装方案动态控制模型
Dynamic Control Model for Precast Components Hoisting Scheme
预制构件吊装包含识别、吊运和安装三个环节,各环节均可能出现阻碍吊装推进的不利因素,加之吊装方案可能发生变更,使得吊装过程控制具有显著的非静态特征。本文融合Blender可视化技术、RFID技术和云计算技术,构建了吊装方案动态控制体系:吊装前,基于Blender技术对最优吊装序列方案进行可视化模拟;吊装中,依托RFID-云计算技术建立预制构件吊装过程监控机制,实时追踪潜在影响因素;吊装后,界定吊装序列调整的问题边界,解析多类影响因素的作用机理与影响程度,设计吊装序列动态调整机制,并通过改进遗传算法的案例仿真验证了该机制的有效性,最终实现预制构件施工过程的精准管控与集约化管理。
The hoisting of prefabricated components comprises three stages: identification, hoisting, and installation. Adverse factors that hinder the progress of hoisting may arise at any stage, and potential changes to the hoisting scheme further render the control of the hoisting process inherently dynamic rather than static. To address this, this study integrates Blender visualization technology, RFID technology, and cloud computing technology to establish a dynamic control framework for hoisting schemes. Specifically, prior to hoisting, Blender is employed to conduct visual simulations of the optimal hoisting sequence scheme. During hoisting, an RFID-cloud-based monitoring mechanism is implemented to track potential influencing factors in real time. Post-hoisting, the scope of hoisting sequence adjustments is defined, the mechanisms and impact degrees of various influencing factors are analyzed, and a dynamic adjustment mechanism for hoisting sequences is proposed. Case simulations utilizing an improved genetic algorithm validate the effectiveness of this mechanism, ultimately enabling precise control and intensive management of the prefabricated component construction process.
