通过对节点位置法的深入研究和大量的编程实践,发现原节点位置法算法不够完整,经常出现错误识别的现象,对此提出了改进方法,并给出了完整的程序框图。应用改进节点位置法后发现,对于同一规模的通风网络,原节点位置法误识别率高达39.8%,改进后的节点位置法误识别率为0。改进节点位置法能够快速准确地识别角联风路,可以广泛应用于矿井通风系统可靠性与稳定性分析。

With the deep study on the node location method, great programming practices showed that the original node location method algorithm was not complet ed and would often cause wrong distinguished phenomena.Thus an improved method was provided and a completed program diagram was provided.The application of t he improved node location method showed that as for a same scale ventilation network, the wrong distinguishing rate of the original node location method was high and was 39.8%. The wrong distinguishing rate of the improved node location method was 0.The improved node location method could rapidly and accurately distinguish the diagonal air way and could be widely applied to analyze the reliability and stability of the mine ventilation system.
