The present invention relates to a control device of a line changer using power line communication, which transmits to a line changer through a power line, and transmits a switching result and a real-time state of the line changer to a linkage device through a power line.

철도선로변에 설치되어 현재 사용중인 신호설비는 신호기, 선로전환기 등이 있다. 역기기실에 있는 제어장치가 이러한 신호설비를 제어하기 위해서는 역기기실과 신호설비간에 여러 종류의 전원선과 통신선을 설치한다.The signaling equipment currently installed on the railroad tracks includes signal and line converters. In order to control such signaling equipment by the control unit in the station equipment room, various kinds of power lines and communication lines are installed between the station equipment room and the signal equipment.

도 1은 종래 역기기실과 현장 신호설비의 연결도이다. 도 2는 종래 선로전환기 제어에 대한 상세도이다. 도 1 및 도 2에서 보는 바와 같이 역기기실에 있는 연동장치가 현장에 있는 신호설비인 선로전환기(230)를 제어하고 결과를 확인하기 위해서 전동기전원선(252), 제어전원 입력선(253) 및 표시계전기 출력선(251)을 설치 한다.1 is a connection diagram of a conventional station equipment room and the field signal equipment. Figure 2 is a detailed view of the conventional line switch control. As shown in FIGS. 1 and 2, the interlock device in the station equipment room controls the line switch 230, which is a signal facility in the field, and checks the result of the motor power line 252, the control power input line 253, and the result. Install the display relay output line (251).

선로전환기(230)를 정위 또는 반위로 제어하기 위해서 역기기실에 있는 연동장치의 연동논리부(100)는 열차가 주행할 진로의 탐색, 진로의 쇄정 등의 조건을 확인한 후 기기랙(200)의 분전반(220)에 있는 계전기(도시되지 않음)를 작동하여 선로전환기 접속단자(240)로 제어전원 입력선(253)을 통해 제어신호를 송출한다. 선로전환기(230)는 입력신호인 제어전원이 들어오면, 입력신호의 정보내용에 따라 선로전환기(230)의 내부에 있는 계전기가 작동하여 전동기를 구동한다. 전동기의 구동이 완료되면, 선로전환기(230)가 기계적으로 쇄정이 이루어지고, 선로전환기(230)의 전환정보인 출력신호가 기기랙(200)의 분전반(220)에 있는 표시계전기를 작동시킨다. 연동논리부(100)는 표시계전기의 작동을 검지하여 선로전환기(230)의 전환을 확인할 수 있다. 미설명부호 250은 신호등을 나타낸다.The interlocking logic unit 100 of the interlocking device in the station equipment room to control the line changer 230 in the stationary or anticounter, after checking the conditions such as the search for the course on which the train will run, the correction of the course, and the like of the machine rack 200.
