摘　　要：传统的井下人员定位技术(如RFID定位)存在定位误差大、成本高、布线困难等问题,在适应环境、成本能耗、定位精度等综合考虑下设计了基于ZigBee的井下巷道人员定位系统。该系统以CC2530作为定位模块,以ZigBee协议为核心的Mesh网络作为传输方式,达到实时监测井下人员位置的功能。首先,使用卡尔曼滤波算法对接收到的RSSI值进行数据处理;其次,对RSSI值进行阈值优化,将RSSI值经由传输系统上传至监控管理中心;最后,利用三角形加权质心算法对未知节点进行求解定位。针对该定位系统,提出了一种改进的RSSI算法,在定位精度上提高了70%左右,且不依赖于锚节点的数量,具有较好的应用价值。Traditional underground personnel positioning technology(such as RFID positioning)has problems such as large positioning error,high cost,and difficult wiring.Therefore,a ZigBee based underground roadway personnel positioning system is designed based on comprehensive considerations such as environmental adaptability,cost and energy consumption,and positioning accuracy.The system uses CC2530 as a positioning module,and a Mesh network with ZigBee protocol as the core as a transmission method,thereby achieving the function of real-time monitoring the location of underground personnel.Firstly,a Kalman filtering algorithm is used to process the received RSSI value.Then threshold optimization of the RSSI value is followed,which is uploaded to the monitoring management center through the transmission system.Finally,a triangular weighted centroid algorithm is used to solve and locate unknown nodes.An improved RSSI algorithm is proposed for this positioning system.Simulation results show that the algorithm improves positioning accuracy by about 70%,and does not depend on the number of anchor nodes,having better application value.
