摘要
基于ZigBee技术的定位系统定位误差大,不能满足智能化建设需求,提出一种基于超宽带(UWB)技术的煤矿精确定位系统。分析非对称双边双程测距(DS-TWR)的时间测距算法的定位原理,结合煤矿巷道属于狭长的空间环境特点,采用单个读卡分站实现精确定位和行走方向判断。实验结果表明,该系统定位精度误差小于30 cm,无线通信距离半径大于400 m,能够满足当前煤矿人员定位的精度要求。
Positioning system based on ZigBee technology positioning error is big,can't meet the demand of intelligent construction,put forward a kind of precise positioning system of coal mine based on ultra wideband(UWB)technology.Analyzed the asymmetric double-sided two-way ranging(DS-TWR)time ranging algorithm positioning principle,combined with the characteristics that coal roadway has long and narrow space environment,used a single card read substation to realize accurate positioning and the direction of walking.The experimental results show that the system positioning precision error is less than 30 cm,and wireless communication distance radius is larger than 400 m,which can satisfy the demands of the current coal mine personnel positioning accuracy.
