A Development for Serial Data Communication Arbitration Module in Redundant System

여분을 갖는 시스템의 시리얼데이터통신 중재모듈의 개발

This paper show serial communication method in order to design how to interface between fault tolerant systems with redundancy. Problem has been in the method that fault tolerant system had switched of serial data with common switching device. This problem degrade reliability in itself and total system which is interfaced with that serial communication system. So Arbitration module of serial communication which is suggested in this paper can improve the reliability using voter algorithm which fault is detected passively.
