针对矿井巷道单参数监测无线传感器网络无法实现对煤矿环境全面监测的不足,提出了一种基于网格型无线传感器网络的煤矿环境多参数监测系统.该系统在一个节点采用多种传感器对矿井环境进行实时综合监测,及时捕捉征兆信息,加以分析处理,可以更有效地预防事故的发生.设计了结合中断预警功能的基于周期巡检的多参数信息采集工作方式,以及该工作方式需要的支持技术:路由机制、端节点的工作时隙分配原则与数据的聚合处理.提出了基于剩余电池量的最小跳数路由协议与树形路由相结合的路由协议,并提出了网络地址再利用策略.模拟矿井巷道环境测试与实际煤矿巷道测试结果表明,本系统可以实现对煤矿环境的全面监测,试验效果良好.
Aiming at the shortages of mine tunnel single parameter monitoring wireless sensor network can not realize the comprehensive monitoring of coal mine environment, a multi-parameter coal mine environment monitoring system based on grid wireless sensor network is proposed. The system uses a variety of sensors in a mine environment Real-time comprehensive monitoring, timely capture of the symptom information, analysis and treatment can be more effective in preventing accidents.Design of the multi-parameter information collection method based on periodic inspection combined with the interrupt early warning function, as well as the support technology : Routing mechanism, the principle of working time slot assignment of end nodes and aggregation of data.A routing protocol based on the minimum hop count routing protocol and tree routing is proposed and a strategy of network address re-use is proposed. Mine roadway environment test and real mine roadway test results show that the system can achieve a comprehensive monitoring of the coal mine environment, the test results are good.
