Abstract EN
Aiming at the large positioning errors of traditional coal mine underground locomotive, an improved received signal strength indication (RSSI) positioning algorithm for coal mine underground locomotive was proposed.
The RSSI value fluctuates heavily due to the poor environment of coal mine underground.
The nodes with larger RSSI value corrected by Gaussian-weighted model were selected as beacon nodes.
In order to reduce the positioning error further, the estimated positions of the locomotives were corrected by the weighted distance correction method.
The difference between actual position and estimated position of beacon node was regarded as the positioning error and was given a corresponding weight.
The results of simulation show that the positioning accuracy of Gaussian-weighted model is better than statistical average model and Gaussian model and it has a high positioning accuracy after correcting positioning error correction.
In the 10 m of communication range, positioning error can be maintained at 0.5 m.
