Abstract

이중화된 상태에서 기존에 제어하는 포트를 최소화할 수 있는 입출력 인터페이스부를 사용하여 제어할 수 있도록 하고 어느 한쪽의 전원이 오프 되더라도 16포트 지원할 수 있는 전원공급 먹싱하기 위해 전원공급을 위한 제1,2전원공급부를 제1,2직렬포트 인터페이스와 공통으로 연결시켜 어느 한쪽이 오프 되더라도 항상 전원 공급이 되도록 하고 제1,2직렬포트 인터페이스부에 의해 터미널부와 연결되어 RS-232C 전송방식으로 터미널과 송수신데이터(RXD,TXD)를 전송하고, 제1,2직렬 입출력 처리부를 시스템 주제어부의 버스(VME BUS)와 연결되어 시스템과 데이타를 전송토록 되어 있다.First and second power supply for power supply in order to control by using I / O interface part that can minimize the existing control port in a redundant state and support 16 ports even if one power is off Connect the supply to the first and second serial port interface in common so that power is always supplied even when one of them is off, and is connected to the terminal by the first and second serial port interface to transmit and receive data to and from the terminal via RS-232C transmission. (RXD, TXD), and the first and second serial input / output processing units are connected to the VME BUS of the system main controller to transmit the system and data.
