摘　　要：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.In order to overcome the shortcomings of wireless sensor networks for single parameter monitoring in coal mines, a multi-parameters monitoring system for coal mine environment based on mesh structured wireless sensor network is proposed. Multi-kinds of sensors in a wireless node were adopted in the system, such that the integrated monitoring for coal mine environment parameters was achieved. By this way, the premonition information of accident can be caught and analyzed in time, so that coal mine accidents can be avoided significantly. The mode of multi-parameters collection, i. e. periodic monitoring routine combined with interrupt service, is proposed. The supporting technology such as routing mechanism, slot allocation principles for wireless end device and data aggregation was also designed. A routing method, which combines least-hop routing protocol of node remaining energy and tree protocol, is proposed. Besides, node address recycling strategy was also proposed. The experiment results carried out both in the laboratory and underground coal mine show that the designed system can monitor coal mine environment parameters effectively.
