3DGIS技术在智慧消防的典型案例-市政消火栓水压监测系统

按照“平台优先、应用至上”建设思路，采取“1+1”模式，即一个“系统总体”(共性平台)和一个“分类专项”(应用示范——市政消防栓智能管理系统)，通过技术和应用创新，成为重庆“智慧消防”建设的实战平台、科研平台、演练平台和培训平台。

　　以虚拟现实技术为基础，以数据为核心，以流程为线索，以事件为驱动，综合应用GIS、物联网、人工智能、数据可视化、自动化控制等技术，建立基于3DGIS的市政消火栓管控系统，通过多源多模信息融合、数据分析、模式发现和信息展示，服务于市政消火栓状态监控与管理、事故预警与预测、事件的分析与决策、任务发布与下达等业务应用，并具有信息全景化、数据可视化、流程信息化、预案沙盘化、展示临场化和管理精细化的特点。

　　(1)独立三维场景

　　大坪街道、解放碑街道三维电子沙盘各设计为一个独立的三维场景。

　　(2)辖区外标识

　　辖区外重要的公路等交通干线、附近地区重要的企、事业单位和厂矿，二维地图加名称、文字标识出来。

　　(3)两类三维模型

　　第一类为采用倾斜摄影技术建模，如本项目区域内的大型建筑、地形地貌、市政道路、园林植被等;第二类为手工建模，如消火栓等设备设施及地下供水管网等。

　　(4)倾斜摄影模型大坪街道与卫星图衔接效果

(6)消火栓与现场监测数据集成

　　通过物联网，将消火栓的水压监测设备的监测数据实时上传，并进行集成管理应用。

　　(7)人员定位数据集成

　　(8)平台功能
