根据井下人员定位系统的特点以及ZigBee的特性,提出了基于ZigBee的井下人员定位系统分区域组网的方法,设计了一种分簇路由算法FEECP,同时给出了其在井下的应用模型。仿真结果表明,FEECP算法在路由开销、数据包的成功接收率和端到端的延迟这三个方面表现出了优势。该算法可以快速地进行路由发现,减少路由控制开销,节省能量,同时还可以对井下人员进行精确定位。
According to the characteristics of underground personnel positioning system and the characteristics of ZigBee, a method based on ZigBee-based sub-regional positioning system for underground personnel positioning system is proposed. A clustering routing algorithm FEECP is designed and its application model in underground is given. The simulation results show that the FEECP algorithm has advantages in three aspects: routing overhead, successful reception rate of data packets and end-to-end delay. The algorithm can quickly find routes, reduce routing control overhead, save energy, and at the same time, can accurately locate downhole personnel.
