基于Revit的装配式建筑PC构件信息模块化检索方法

Modular retrieval method of PC component information of prefabricated building based on Revit

为了克服传统装配式建筑PC构件信息索引内容相关度低的问题,本文基于Revit构建了一种新的集索引、存储于一体性的模块化索引方法。该方法首先进行Revit构件信息初步检索,建立等效逻辑,通过信息数据的关键词,引入信息区分,生成包括SN层、扩展层、逻辑层等多层次的检索格式;然后,依靠检索格式设计了信息存储空间,根据索引坐标建立了聚类数据集,生成特征向量和多类型指令信息;最后,依靠VLAD完成上述两部分的归一化处理,保证整体检索集成性,实现PC构件信息的模块化检索。实验数据证明,本文设计的检索、存储一体化的模块化检索方法可以有效提高索引内容相关度和特征准确度。

In order to solve the problem of low content correlation of the traditional assembly building PC component information index,a new modular index method based on Revit is proposed.First,the information of the Revit component is analyzed,and the equivalent logic is established.Second,according to the keywords of the information data,data separation is introduced,and a multi-level logical structure relationship is generated,including the SN layer,the expansion layer,the logic layer and the like.Third,the information storage space is designed based on the index format,and a cluster data set is established according to the index coordinates.Fourth,a feature vector and multi-type instruction information are generated,Finally,the normalization processing is carried out to ensure the integration of the whole search and realize the modular retrieval of the PC component information.The experimental data show that the modular retrieval method of the design retrieval and storage integration can effectively improve the information retrieval effect,and in particular,the correlation degree and the characteristic accuracy of the index content are obviously improved.
