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 a distance measurement parameter in an RSSI distance measurement 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 the plurality of channels to obtain the RSSI values; signal processing stage: processing the RSSI into signal intensity amplitude optimization; and positioning stage: calculating the distance and target node position on a positioning server according to the calculation of each signal intensity. 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 multi-path signal transmission, same-frequency interference, obstacle interference and low coordinate calculation precision of a trilateration method.
