摘要
在煤矿井下安全生产系统中,对井下人员的精确实时定位是一个很重要的任务之一。ZigBee技术以它低功率、低成本、低复杂性等特征,被大量的应用在煤矿井下定位系统中。研究一种基于ZigBee技术的煤矿井下人员新定位算法,采用最邻近的信号强度(NNSS)指纹匹配在煤矿井下进行初步定位,然后运用动态三边测量(DTN)对移动节点进行精确的测距定位,并与其他的经典的定位算法进行比较,结果证明了这种算法是可行的,且明显的能够提高定位的精确度。
the exact position of mobile user plays an important role in location services of underground coal mine. ZigBee technique, for its low power, low cost and low complexity, is usually used in positioning system of underground coal mine. In this paper, a new position algorithm of underground personnel based on ZigBee technology is proposed, in which the NNSS fingerprint match is first adopted for preliminary location, and then dynamic triangular （DTN） location method employed for precise ranging and position. Comparison with other classical location-finding algorithms indicates that the proposed algorithm is feasible, and could remarkably enhance the positioning accuracy.
