Research on Personnel Positioning Technology Based on Improved LANDMARC Positioning Algorithm
In the era of the Internet of Everything,it has become possible to complete personnel positioning supervision through positioning systems,and this technology is also becoming increasingly improved.Cur-rently,local area network personal positioning based on RFID wireless video technology is widely used in employee control,key personnel supervision,and other aspects of smart park.A local area network person-nel positioning algorithm based on RFID is proposed.By optimizing the LANDMARC algorithm,Gaussian smoothing filters and Kalman filters are introduced into the collected signals to remove noise that affects signal strength and improve the stability of the positioning algorithm.In response to the problem that the positioning accuracy of the LANDMARC positioning algorithm is greatly affected by the K value,a logistic regression model is introduced into improve the positioning accuracy of the algorithm,effectively solving the problem of large positioning accuracy errors in RFID in metal,water,and other obstacles,reducing ex-ternal interference,and providing technical means for precise positioning of personnel.
