Abstract

Tracking the location of patients in medical facilities is important to guarantee the patients' safety and to improve the service quality. Previous studies related to location tracking systems based on Bluetooth communication need numerous prerequisite information and multiple devices to improve the accuracy. In this paper, we propose a beacon-based space partition scheme that assigns different arrangement patterns of beacons to different spaces and composes groups with the similar value of RSSI to minimize prerequisite information and the number of beacons. The proposed scheme considers a pattern arrangement scheme to minimize intereference between neighbor patterns. We also verified the applicability of our scheme to monitor the patient location by using experimental results.

의료시설 내에서 이동하고 있는 환자의 위치를 확인하는 것은 환자의 안전을 보장하고 의료서비스 질의 향상을 위해서 중요하다. 기존의 블루투스를 활용한 실내위치확인 시스템에서는 정확도 향상을 위해서 많은 사전 정보와 다수의 장치를 활용해야하는 문제가 있었다. 본 논문에서는 서로 다른 공간에 다른 패턴으로 비콘을 배치하고 동일한 수신신호강도를 갖는 비콘들을 그룹화하여 사전 정보 없이 소규모의 비콘만으로 공간을 인식하는 기법을 제안한다. 제안 기법에서는 인접 패턴간의 간섭을 고려하여 이를 최소화 할 수 있는 패턴 배치 기법을 연구했다. 또한 실험을 통해 제안 기법이 환자 위치 확인 시스템에 적용가능하다는 것을 검증하였다.
