Abstract

In this paper, we proposed indoor positioning system using RSS(Received Signal Strength) positioning method and TSS(Transmission Signal Strength). The main point in the paper is to improve reliability of accuracy positioning with the area recognition algorithm and probabilistic algorithm, which can be effectively used indoor. In the test in 1-dimensional or 2-dimensional spaces, also we checked effective positioning system considered environment of propagation that is changed by reflection, refraction and multipath in according to space form. It is necessary to find place where urgent situation happen and quickly to respond the situation for patients or the weak. Therefore, we expect the positioning system proposed can apply to the field of traffic IT.

본 논문에서는 Zigbee 무선통신모듈과 RSS(Received Signal Strength) 측위 방식을 이용하여 다단계 TSS(Transmission Signal Strength)기술을 적용한 실내측위 시스템을 제안하고자 한다. 특히 실내공간에서 효과적으로 사용할 수 있는 확률적 알고리즘과 영역인식 알고리즘을 적용하여 위치정+확도에 대한 신뢰를 높이고자 하였다. 또한 1차원공간과 2차원 공간에서의 실험을 통해 공간의 형태에 따라 반사나, 회절, 멀티패스 등의 영향으로 변화하는 전파환경을 고려한 효과적인 측위 시스템을 확인하고자 하였다. 특히 약자나 환자에 대한 긴급 상황 발생 시 해당 위치를 찾아 신속한 대응이 필요하다. 따라서 본 연구의 측위 시스템은 교통 IT 분야에 적용하여 사용 될 수 있을 것으로 기대된다.
