基于Unity 3D的被困人员逃生路径系统研究与设计

Research and Design of Escape Path System for Trapped People Based on Unity 3D

近年来,伴随我国城市规模的持续拓展,人口密度以及建筑数量大幅增加,但这也导致火灾数量日渐增长,使得城市面临的消防压力逐渐增大,因火灾造成的人员和财产损失也逐年增多。传统的消防系统监控设备在建筑内部发生火灾时,大量的浓烟会使其失灵,使其无法准确捕获被困人员的位置信息,从而耽误最佳的救援时机。因此,在基于Zigbee室内定位的基础上利用MYSQL数据库收集到的被困人员位置信息结合Unity 3D技术构建虚拟场景,利用Dijkstra算法进行最优逃生路径的规划,进而重现被困人员所处的真实环境、位置数据等,为消防救援人员提供直观、可靠、便捷的营救模式。

In recent years,with the continuous expansion of China’s urban scale,population density and building number increased significantly,but it also leads to the increasing number of fires,which makes the city is facing the fire pressure gradually increased,the loss of personnel and property caused by fire also increased year by year. In the event of a fire inside a building,traditional fire monitoring equipment can be disabled by heavy smoke,preventing it from accurately capturing the location of trapped people and thus delaying the optimal timing of rescue. Based on zigBee indoor positioning,this paper uses the location information of trapped people collected by MYSQL database to build virtual scenes combined with Unity 3D technology,and uses Dijkstra algorithm to plan the optimal escape path,so as to reproduce the real environment and location data of trapped people and provide intuitive information for fire and rescue personnel. Reliable and convenient rescue mode.
