Intelligent Perception and Anomaly Information Processing of Power Engineering Smart Construction Site Platform Based on 3DGIS + BIM: A Case Study of Chongming Yangtze River Crossing Project

In order to improve the information management level and platform operation load rate of tower construction in power engineering, it is necessary to introduce a GIS + BIM engine based on B/S architecture to develop a smart construction site platform for power engineering tower construction. The power engineering smart construction site platform based on 3DGIS + BIM integrates 3D geographic information data, oblique photography data, BIM model data flow, and dual-arm monitoring data flow of the tower construction site, realizing real-time monitoring, personnel positioning, and intelligent electronic fence warning, which can improve the level of personnel operation risk control. By introducing an instance database, collecting data information, screening abnormal information, and preprocessing the information before information management through clustering analysis, and the smart construction site platform achieves intelligent processing and clustering of anomalous information in power engineering. Based on the Internet of things and the collaborative mechanism of power engineering projects, a management decision model based on the browser and server is constructed to achieve intelligent decision-making and digital management of risk information in smart construction sites. Comparative experiments demonstrate that the smart construction site platform designed in this paper can avoid platform operation load caused by excessively large data and improve the efficiency and comprehensive management level of platform information management.
