무선 AP를 이용한 열차제어시스템의 차상 ATP/ATO 데이터 로그 수집 장치 구현

In this paper, the DLGU(Data Log Gathering Unit) is implemented for gathering log data of onboard ATP(Automatic Train Protection) and ATO(Automatic Train Operation). By using wireless AP(Access Point), the implemented DLGU is communicated with onboard ATP and ATO; therefore, it is possible to inspect the train status in remote locations while a train is running in driverless mode. Experimental results show an availability of the implemented DLGU.
