A Study On The Reliability Characteristics of Fail-Safe Control Logic
고장-안전 제어논리의 신뢰성 특성에 관한 연구
Abstract
This paper modelled the fail-safe control logic through the frequency coding input and designed the 3-out of-6 self checker using the error detect coding method of information redundancy. In addition, this paper also peformed the reliability parallel numeric analysis regarding single module between fail-safe. control logic module and TMR(Triple Modular Redundancy), therefore, we achieved the result that the fail-safe control logic increases a functional reliability because of decreasing system waste cost and functional overhead rather than the existing hardware redundancy method.
