Description
Claims (1)
- 선두차량을 포함하는 다수의 차량이 연결되어 있고, 각 차량에는 통신모듈이 분산되어 있으며, 각 통신모듈들이 원형(Ring) 구조로 연결되어 있는 전동차의 차량간 통신 장치에 있어서, 상기 각 통신모듈이 VME 버스를 통해 통신 프로세서와 접속되어 송수신 신호를 구동하는 구동용 집적회로(10)와; 상기 구동용 집적회로(10)에서 출력되는 신호를 입력받아 현재 전동차의 상태 정보를 전송하거나 이전 전동차의 상태 정보를 전송하도록 하는 논리 회로(20); 및 상기 논리 회로(20)의 출력에 따라 전기적인 신호를 광신호로 변환하고, 수신된 광신호를 전기적인 신호로 변환하는 광모듈(30)로 이루어지고, 상기 논리 회로(20)는 상태 정보를 전송하여야 하는 전동차에 '하이'레벨로 인가되는 통신마스터(COMM_MASTER)신호가 셀렉팅 단자(S1)로 입력되고, 송신요구(RTS)신호 및 '로우'레벨의 신호가 제1,제2 입력단자(A1,B1)로 입력되는 제1멀티플렉서(21)와; 상기 제1멀티플렉서(21)의 출력 단자(Y1)의 신호가 셀렉팅 단자(S2)로 입력되고, 현재 전동차의 상태 정보(TXD) 및 이전 전동차의 상태정보(OPT_RXD)가 제1, 제2 입력 단자(A2,B2)로 입력되며, 출력 단자(Y2)의 신호가 다음 전동차로 전송되는 제2멀티플렉서(22)를 포함하여 구성된 것을 특징으로 하는 전동차의 광신호 전송 회로.
