摘　　要：煤矿的井下地形狭长，通信条件复杂，传统的定位算法不考虑待定位节点之间的连通约束，定位精度较差，因此提出一种技术节点连通协作的定位算法使用在煤矿井下定位系统中，以CC2430芯片作为硬件支撑与CC2591处理器芯片结合构造无线收发模块，ZigBee协议栈控制无线信号的收发与传输；在节点定位模块中将节点进行DV—hop的粗略定位后使用分布式迭代提高定位精度，将定位信号通过总线传输到井上的控制端；实验证明，该系统对煤矿井下的人员定位精度比DV—hop算法提高15％～20％，定位模块算法的收敛速度与计算复杂度较传统的算法降低10％，证明该系统具有稳定的网路性能与很强的实用价值。Coal mine underground terrain is long and narrow, communication condition is complex, traditional localization algorithm does not consider a node to between the connected constraint, positioning accuracy is poor. This paper puts forward a technology node connected collaborative localization algorithm used in coal mine underground positioning system to CC2430 chip as the hardware support and CC2591 processor chip combining structure wireless transceiver module, ZigBee protocol stack control wireless signal receiver and transmitter and transmission. In the node positioning module will node for DV--hop is the rough localization using distributed iterative improves positioning accuracy, the positioning signal through the bus transmission to invoke control end. The experimental results prove that the system for mine personnel positioning accuracy than DV--hop algorithm is increased by 15% to 20%. Positioning module algorithm convergence speed and calculation complexity than traditional algorithm reduced by 10%. Prove that the system has a stable network performance and strong practical value.
