面向火灾的通风网络解算与三维可视化表达

Calculation Method and 3D Visualization of Fire-oriented Ventilation Network Calculation

通风网络解算是地下矿火灾仿真的前期工作基础,如何进行面向火灾的地下矿通风网络解算及建立相应可视化系统十分重要。针对此,构建通风网络系统图模型,以斯考德-恒斯雷算法为基础,采用数据库技术,对通风网络解算结果进行优化储存,实现了网络解算结果的高效快速调用。并利用可视化技术,实现了通风网络解算结果的可视化图文表达,为进一步的火灾仿真奠定了基础。最后,以某金属矿山为例,运用Java语言和JOGL绘制技术,实现了地下矿通风网络解算及其可视化图文表达,证实了该算法流程的可行性和有效性。

As a previous work of underground mine fire disaster simulation, how to establish calculation method and 3D visualization techniques of fire-oriented underground mine ventilation network plays an important role. As a result, a ventilation network graph model is established, and then a ventilation calculation based on H-Cross algorithm is constructed. In this paper, the calculation result can be saved in the database,which can increase user＇s call efficiency. Furthermore,3D visualization of ventilation network calculation is implemented by 3 D visualization technique, which provides a basis for fire disaster simulation. At last,with an application in a typical underground metal mine ,ventilation network calculation and 3D visualization is put into effect by Java and JOGL, which verifies that the technique is feasible and effective.
