| 中文摘要 | An RSSI positioning method based on frequency-hopping spread spectrum technology, comprising: calibration stage: measuring the RSSI values of a plurality of channels at fixed points, and recording and calculating the ranging parameters in an RSSI ranging model; system preparation: deploying a positioning anchor node, and realizing synchronization between a target node and the anchor node; conducting communication on the target node by respectively utilizing a plurality of channels to obtain the RSSI values; signal processing stage: processing the RSSI into signal strength amplitude and performing optimization; and positioning stage: calculating a distance and the target node position on a positioning server according to each of the signal strength. The present invention solves the problem that low RSSI positioning precision cannot satisfy the actual requirements because a traditional RSSI positioning method is limited to factors such as multipath signal transmission, co-channel interference, obstacle interference and low coordinate calculation precision of a trilateration method. |
