改进RSSI算法在煤矿动目标定位中的设计与实现

Design and Implementation of Rssi Algorithm in Mine Moving Target

无线传感器网络(WirelessSensorNetwork,WSN)被誉为改变世界的10大技术之一,应用于广泛的领域内,实现大规模的目标监测与追踪、基于位置信息的路由等。提出一种基于RSSI理论模型,通过改变信标节点的放置方法,提高定位精度,信标节点避免位于一条直线上,增大新表节点的折线距离,提高ABCR的精度;引入加权因子对DV-Distance进行改进,反映出信标节点对目标节点影响力的大小,提高定位精度和稳定性。并引入一种智能定位思想,定时对定位参数进行校正,进一步提高定位精度,然后进行巷道建模,实现硬件系统的设计。

WSN is known as one of the top 10 technology changing the world, used in a wide range of areas to achieve the goal of large-scale monitoring and tracking, routing information based on location, etc. This paper presents a theoretical model based on RSSI by changing the beacon nodes placement method to improve the positioning accuracy, avoid beacon nodes located on a straight line, a line from the new table node to increase and improve the accuracy of ABCR. Introduction of weighting factors to improve DV-Distance. Beacon node size reflects the target node influence, improve positioning accuracy and stability. And the introduction of an intelligent positioning thought, time to correct positioning parameters to further improve positioning accuracy, then the roadway modeling, design hardware system implementation.
