Claims (3)
- 차륜(5) 또는 차륜과 연계하여 회전운동하는 부재의 회전속도를 감지하여 차량의 속도를 검측하는 차량속도센서(5)와; 침목 등 노반(2)에 설치되며 궤도정보를 내장하고 있는 RFID TAG(3)와; 철도차량에 탑재하여 이 TAG를 가까이 지나갈 때 무선으로 TAG의 내장정보를 받아들이는 RFID READER와 PROCESSOR로 구성된 RFID차상장치(4)와; 이들 수집된 자료로부터 실시간으로 철도차량의 궤도상의 위치를 계산하는 데이터처리장치(6)로 구성하고, 킬로포스트간의 실제거리와 기준거리정보와의 차이를 해당 구간의 전 영역에 걸쳐 보간법으로 보정하는 방법으로 위치보정을 행하는 궤도위치인식 및 위치보정시스템
- 상기 1항에 있어서, 두 킬로포스트간의 실제거리와 기준거리정보와의 차이를 해당 구간의 전 영역에 걸쳐 보간법으로 보정하는 방법에 있어서;
이 구간의 기준거리에 대비한 실제거리의 비율인 거리보정계수 또는 기준거리에 대비한 실제거리의 차이값인 보정거리를 보정정보라 칭할 때; 이 위치의 킬로포스트의 위치에 설치한 RFID TAG내부에 이 보정정보를 절대위치정보 등과 함께 기억시켜두고, 이 RFID를 통과하는 차량의 RFID차상장치가 절대위치와 함께 이 보정정보를 인식하게 하여, 절대위치정보에 더하여 속도센서정보를 이용한 주행거리를 계산할 때 이 보정정보를 반영한 주행거리를 계산함으로써 보정된 궤도위치정보를 실시간으로 계산하는 기능을 가지는 궤도위치인식 및 위치보정시스템
- 상기 1항에 있어서, 킬로포스트 간의 실제거리와 기준거리정보와의 차이를 해당 구간의 전 영역에 걸쳐 보간법으로 보정하는 방법에 있어서;
이 구간의 기준거리에 대비한 실제거리의 비율인 거리보정계수 또는 기준거리에 대비한 실제거리의 차이값인 보정거리를 보정정보라 칭할 때;
이 보정정보를 차상장치, 데이터처리장치 또는 지상컴퓨터에 저장해두고서, 추후 궤도측정데이터의 측정위치보정 시에 이를 반영하여 후처리 방식으로 보간하는 기능을 가지는 궤도위치인식 및 위치보정시스템
