基于无人机技术的村落建筑群火灾蔓延模型的构建

Establishment of fire spread model for village buildings based on UAV

建筑信息匮乏、缺乏图纸是村落建筑群火灾防控面临的首要问题。针对传统的现场测绘工作量大、费用高、获取数据信息不精确等问题,在现场勘察获取典型单体建筑详细建模数据的基础上,采用无人机倾斜摄影技术获取村落建筑群地理信息数据,并建立村落建筑群火灾蔓延分析模型。进一步采用简化分析方法确定建筑群不同建筑起火后的火灾蔓延情况及火灾蔓延损失。最后以云南省某村落为研究对象,建立了该村落的火灾蔓延模型并分析了火灾蔓延风险。结果表明:该方法能有效获取村落建筑群火灾蔓延模型的建模数据,并为后续的火灾蔓延风险分析提供数据支持。

The lack of building information and drawings is the primary problem facing the fire prevention and control of vil-lage buildings.Aiming at the problems of heavy workload,high cost and inaccurate data obtained from traditional on-site sur-veying and mapping,based on the detailed modeling data of typical single buildings obtained from on-site investigation,this pa-per uses UAV tilt photography technology to obtain the geo-graphic information data of village buildings,and establishes the analysis model of fire spread of village buildings.The sim-plified analysis method is further used to determine the fire spread and fire spread loss of different buildings in the building complex.Finally,this paper takes a village in Yunnan Province as the research object,establishes the fire spread model of the village and analyzes the risk of fire spread.The results show that this method can effectively obtain the modeling data of the village building fire spread model,and provide data support for the subsequent fire spread risk analysis.
