摘要
随着航空发动机控制技术的发展,全权限数字电子控制(FADEC)系统的可靠性设计变得越来越重要;在FADEC系统中, 同步设计对于提高航空发动机全权限数字式电子控制器的可靠性具有重要的意义;为了解决如何在FADEC系统中实现双机时钟级同步设计,简要的分析了应注意的问题;随即介绍了设计中采取软硬件相结合来同步两计算机实时时钟的基本方法,在实践中证明了该方法是行之有效的。
With the development of Aeroengine control technology, reliability of full authority digital electronic control （FADEC） becomes more and more important. The synchronization design is very important for improving reliability in Aeroengine FADEC system. Attentive problems were analyzed briefly in order to realize the synchronization of real time clock design between the two computers in FADEC system. To carry out synchronization of real time clock design between the two computers in FADEC system, basal method that adopts software and hardware integrated is introduced in succession. The application indicates that this method is effective.
