Smart Bluetooth beacon based on LoRa Positioning method and system research

Abstract In the era of Internet Everything, applications based on real-time location continue to appear in various industries. The indoor and outdoor positioning, analysis management personnel objects can effectively improve efficiency production management, which is great significance many use Bluetooth beacon positioning has advantages low energy consumption, cost, fast data transmission speed. However, real life, there are two obstacles receiving signals, easily affected by environment need for frequent on-site maintenance. This paper designs implements a new type LoRa-based smart beacon, be quickly connected LoRa. Online monitoring remote control achieve better adaptation environment, fit signal attenuation model deployment time. Traditional strength solutions have their own limitations. order accuracy universality algorithm, view density beacons, not good anchor circle situations, an optimized weighted centroid scheme integrating greedy strategy proposed.
