在研究基于ZigBee技术矿井人员定位中,针对矿井人员密集区域和信号衰减严重区域通信时可能造成信号冲突的问题,导致未知节点在跟踪定位过程中存在着一定的数据丢失。借鉴分簇算法,结合接收信号强度指示(RSSI),提出了组团协议。组团协议不让每个未知节点都给信标节点发送信息,只从未知节点中选出的一个代表与信标节点进行通信,从而避免通信冲突和增强系统的健壮性,最后对组团协议进行了仿真。
In the research of mine personnel positioning based on ZigBee technology, the signal conflict may be caused when the communication between mine-intensive area and severe signal attenuation area is caused, which leads to some data loss of unknown node in the process of tracking and locating. Drawing on the clustering algorithm, combined with the received signal strength indicator (RSSI), proposed a delegation agreement. The grouping protocol does not allow each unknown node to send information to the beacon node, and only one selected node from the unknown node communicates with the beacon node to avoid communication conflicts and enhance the robustness of the system. Finally, the delegation protocol is simulated .
