Abstract

The invention discloses a wireless indoor positioning method and system based on an attention mechanism. The positioning precision is high. The method comprises the following steps: arranging a plurality of beacon nodes with Ibeacon beacons and a plurality of reference nodes with known positions indoors; continuously collecting RSSI values between each reference node and all beacon nodes at multiple moments, and sorting the RSSI values corresponding to each reference node at each moment to form an RSSI value sequence corresponding to each reference node at each moment; Training the RSSI valuesequence corresponding to each reference node at each moment by using a time convolution network model to obtain a probability sequence of each reference node; And carrying out weighting processing onthe probability sequences of all the reference nodes to obtain a final positioning position.

Description

technical field [0001] The present disclosure relates to the field of indoor positioning, in particular to a wireless indoor positioning method and system based on an attention mechanism. Background technique [0002] Positioning technology plays a very important role in indoor navigation, smart medical care, mobile social and other fields. With the rapid development of the mobile Internet, indoor positioning technology has great prospects for the global industry market. The current indoor positioning methods are mainly divided into two types: ranging positioning method based on signal strength; fingerprint positioning method based on feature matching. The positioning method based on the fingerprint database uses the multipath propagation of the wireless signal to construct the RSSI (Received Signal Strength Indicator) fingerprint map, which can better adapt to the indoor environment, and the hardware cost is relatively low, so it has received extensive attention and resear...
