Abstract

본 발명은 동일한 두 보드를 이용하여 두 보드 중 하나의 보드가 작동하고 있다가 그 보드에서 장애가 발생했을 경우 또다른 보드를 작동하게 하는 보드절체회로에 관한 것으로, 일측 보드의 장애발생신호를 입력받는 제1인버터(6)와, 상기 제1인버터(6)의 출력을 베이스단으로 입력받고 전원(Vcc)을 컬렉터단으로 입력받는 트랜지스터(7)와, 상기 트랜지스터(7)의 이미터단에 연결되는 제1저항(R1)과, 상기 트랜지스터(7)의 이미터단에서 출력되는 신호를 입력받아 타측보드 인에이블 신호를 출력하는 제2인버터(8)와, 상기 트랜지스터(7)의 이미터단에 일측이 연결되고 타측에 전원(Vcc) 및 타측 보드(2)의 장애발생신호가 인가되는 제2저항(R2)를 구비하는 것을 특징으로 하여, 두 보드사이에 어느 한 보드가 고장났을 경우 전기적 절체가 가능해지는 효과가 있다.The present invention relates to a board switching circuit for operating another board when one of the two boards is operated using the same two boards and a failure occurs in the board, and receives a failure occurrence signal of one board. A first inverter 6, a transistor 7 receiving an output of the first inverter 6 to a base end and a power supply Vcc to a collector end, and an emitter end of the transistor 7. One side of the first resistor R1 and the second inverter 8 which receives the signal output from the emitter terminal of the transistor 7 and outputs the other board enable signal, and one side of the emitter terminal of the transistor 7 The second resistor (R2) is connected to the other side is applied to the power supply (Vcc) and the failure signal of the other board (2), characterized in that, if any one of the two boards between the electrical switch is possible Have a disintegrating effect .
