本文介绍了一种用于矿山安全监测的无线传感器网络。根据地下矿井巷道的特点和矿井安全监测的需求，提出了一种分布式异构分层矿井安全监测原型系统，即HHMSM。该系统能够监测瓦斯浓度，并对矿工进行定位。我们提出了一种新颖的基于监听的自适应数据收集方案，该方案利用时间和空间上采样读数的冗余和相关性来减少流量和控制开销，并为大规模传感器网络提供有界的偏移误差。与卡尔曼滤波器等其他更具理论基础的机制相比，该机制易于实现且成本低廉。实验结果表明，与现有的其他无线矿山安全监测系统相比，HHMSM在灵活性、正确性、覆盖范围和寿命方面取得了更好的性能。
This paper describes a wireless sensor network for mine safety monitoring. Based on the characteristics of underground mine gallery and the requirements for mine safety monitoring, we proposed a distributed heterogeneous hierarchical mine safety monitoring prototype system, namely HHMSM This system is capable of monitoring methane concentration, and locating miner. We proposed a novel overhearing-based adaptive data collecting scheme which exploits the redundancy and correlation of the sampling readings in both time and space to reduce traffic and control overhead with a well-bounded offset error for large-scale sensor networks. This mechanism is easy to implement and low-cost compared to other more theoretically based mechanisms such as Kalman filter. Experimental results show that HHMSM achieves better performance on flexibility, correctness, coverage, and lifetime compared with other existing wireless mine safety monitoring systems.
