基于监测覆盖范围的瓦斯传感器无盲区布置

通过建立矿井通风网络的图论模型，提出将监测范围作为传感器部署的理论依据，以节点间风流流经时间作为监测等级，应用覆盖度作为优选最佳测点标准,基于Dijkstra算法和极小支配集算法求得传感器的最佳布点.以一小型矿井通风网络为例，求解瓦斯传感器的最优布点，结果表明监测等级不同对应的安全等级也不同，布点的数量、位置以及监测覆盖度也不同.

No-blind-zone placement of methane sensor based on monitoring coverage

By establishing graph model of mine ventilation network,monitoring scope was applied as the theory base,flowing time between nodes was used as monitoring level,optimum methane sensor placement could be resolved with coverage as the selection standard based on Dijkstra arithmetic and minimal dominant set arithmetic.By using a small mine as an example,methane sensor placement was optimized and the results show that different monitoring level leads to different safety level,number of methane sensors and coverage.
