摘要
Abstract
When the mobile nodes are measured by use of the geometric method,it is important to accurately measure the distance between nodes.Multipath interference and factors of having influence on NLOS errors exist in using ZigBee-based RSSI ranging.First-order filter algorithm is optimized,which is used to filter the RSSI signal.On this basis,this paper establishes a nodal motion state model and uses the Kalman filter to estimate the dynamic ranging,in order to realize the real-time distance measurement of the mobile nodes in the agricultural environment.关键词
