机载计算机内离散量接口功能的设计方法
Design Method of Discrete I/O Function in Airborne-computer
摘要
Abstract
It discusses the design method of discrete I/O function module in airborne-computer,the design requires that on the basis of meeting the demand of basic functions,should adopt the measurements,such as the components selection,derating,increasing robustness, to meet the requirements of reliability for the module. Testability demands a designer pay attention not only to achieve a perfect function, but also to implement high coverage fault detection on hardware. On safety design,the dispersed quantity to indicate a fault in airborne ap-plication environment must be able to timely and exactly declare a fault condition to trigger the alarm prompt,in this paper present a de-sign method of discrete signal declaring circuit with exact instructions ability. In this paper,describe the design idea for the discrete I/O function circuit from basic function,testability,reliability and safety and so on,and give an architecture graph about it for reference.关键词
