数字孪生技术在智慧园区中的实践

The practice of digital twin technology in smart park

通过分析某市开发区的地形地貌和园区安全生产需要,提出了以倾斜摄影测量、地下管线探测、Cesium模型渲染等数字孪生技术为基础,以数字化、智能化理念为目标,考虑园区中的“建筑、设备、安全、环境”等因素,结合物联网、大数据、可视化技术,形成一套完整的实景三维数字化模型园区数字孪生解决方案,即智慧园区数字孪生可视化平台。该平台既能提供厂区、楼宇、河流等区域宏观上的多级可视化,又能进行微观逐层缩放,实现园区从时间到空间的全方位展示和管理,从而全面提升园区规划、建设、发展的信息化管理水平。

Based on the analysis of the topographic features of a city's development zone and the need for safe production in the park,this paper proposes a complete set of solutions based on digital twin technologies including oblique photogrammetry,underground pipeline detection,and Cesium model rendering,aiming at the concept of digitalization and intelligence.This method is composed of the Internet of things,big data and visualization technology,taking into account the factors such as buildings,equipment,security and environment in the park.Through the establishment of a three-dimensional digital model of the park,a digital twinning visualization platform of the smart park is designed.The platform provides multi-level visualization of the plant area,buildings,rivers and other ar⁃eas,and realizes the visualization of the park's macro control and microscopic layer-by-layer scaling,and it also provides the allround display and management from time to space,so as to comprehensively improve the informatization management level of the park's planning,construction and development.
