The present invention relates to a real-time worker indoor positioning method in which a server computer (10), a database (20), a wireless router (30), and a worker terminal (40) are connected through a network, and operation processing is performed by the server computer (10). The method comprises: a step S100 in which a unit distance selection unit (100) of the server computer (10) selects a cell unit distance depending on the size of a target room; a step S200 in which a map generation unit (200) of the server computer (10) generates a signal map in an environment with installations and a signal map in an environment without installations; a step S300 in which a signal reduction rate calculation unit (300) of the server computer (10) calculates the signal reduction rate for each distance of each installation; and a step S400 in which a location information calculation unit (400) of the server computer (10) calculates location information of a user by using the signal reduction rate of step S300. Even in an environment with installations, the present invention has an effect of calculating the user's location with improved location accuracy. 본 발명은 서버컴퓨터(10), 데이터베이스(20), 무선공유기(30) 및 작업자 단말기(40)가 네트워크로 연결되고, 서버컴퓨터(10)에 의해 연산처리가 수행되는 실시간 작업자 실내위치 측위방법으로서, 서버컴퓨터(10)의 단위거리 선정부(100)가 대상 실내 크기에 따른 셀 단위 거리를 선정하는 S100 단계; 서버컴퓨터(10)의 맵 생성부(200)가 설치물이 있는 환경에서의 시그널 맵 및 설치물이 없는 환경 하에서 시그널 맵을 생성하는 S200 단계; 서버컴퓨터(10)의 신호 감소율 산출부(300)가 각 설치물의 거리별 신호 감소율을 산출하는 S300 단계; 및 서버컴퓨터(10)의 위치정보 산출부(400)가 S300 단계의 신호 감소율을 이용하여, 사용자의 위치정보를 산출하는 S400 단계를 포함하는 것을 특징으로 하는 실시간 작업자 실내위치 측위방법이다.
