【摘要】：针对矿井采空区煤自燃在线监测的技术难题,提出了密闭采空区气体-温度-压差无线传感器的设计方案。基于低功耗按需轻量动态多径路由协议,设计出集温/湿度,CO,O_2,CH_4,压差传感器于一体的密闭采空区气体-温度-压差无线传感器;结合采空区遗煤分布规律,确定了大面积密闭采空区高密度网络化测点布置方法,形成了具有可剪裁性、冗余性、鲁棒性等特点的气体-温度-压差无线传感器网络,解决了单点监测范围小、指标单一、特征信息异常反映滞后等问题。试验结果表明,无线传感器性能稳定良好,实现了对采空区气体-温度-压差的动态监测,保障了矿井的安全生产。
[Abstract]:Aiming at the technical problem of on-line monitoring of coal spontaneous combustion in goaf, the design scheme of gas, temperature and pressure difference wireless sensor in closed goaf is put forward. Based on the low power demand dynamic multipath routing protocol, a gas, temperature-pressure difference wireless sensor which integrates temperature / humidity Cost2CH4 and differential pressure sensor is designed, which combines the distribution of coal in goaf. The layout method of high density network measurement points in large area closed goaf is determined, and a gas-temperature-pressure difference wireless sensor network with the characteristics of trimability, redundancy and robustness is formed, which solves the problem that the single point monitoring range is small and the index is single. The characteristic information abnormal reflection lags and so on. The experimental results show that the wireless sensor has good performance and realizes the dynamic monitoring of gas-temperature-pressure difference in goaf and ensures the safety of mine production.
