【摘要】 根据对矿井巷道环境参数监测的需求和矿井巷道地形的特点,提出了一种矿井巷道层次型无线监测无线传感器网络.设计了网络的拓扑控制机制、路由机制,开发了相应的硬件平台和协议栈,并设计了中断和周期性巡检的工作方案.模拟矿井巷道的实际环境进行了实验室试验,试验系统在中断方式下可以实现超限数据的及时传输,在周期性巡检方式下可以实现稳定可靠地对数据进行周期性采集.更多还原

【Abstract】 According to the requirement of monitoring the environment of coal mine laneway and the characteristics of the laneway landform,a kind of hiberarchy wireless sensor network was proposed for laneway monitoring.The topology control mechanism and routing mechanism were designed,correspondingly hardware of the sensor node and the protocol stack were developed,and two work modes for the system were designed.Simulation experiment in the laboratory proves operated well,the data exceeding the threshold could be delivered timely in interrupt mode and data could be periodically gathered steadily and reliably in periodic monitor mode.更多还原
