Design of Warm Restart in Integrated Avionics System

为解决综合化航空电子系统中冷重启动时大电流冲击导致的电子元器件加剧老化问题,以及避免冷重启动时系统中无需重启动部分正常工作被中断现象,提出将热重启动引入综合化航空电子系统设计中。结合综合化航空电子系统的控制结构和处理器的复位功能,分析了热重启动在综合化航空电子系统中实现的可行性,给出了实现热重启动的软硬件设计方法。经过实验验证,热重启动能够有效解决冷重启动方式在综合化航空电子系统的弊端。

Warm restart is proposed in order to solve the problems arising from the process of cold restart in integrated avionics system,which are the aggravation of the aging process of electronic components hit by huge transient current and the interruption of normal functions requiring no restart. According to the control structure of integrated avionics system and the reset function of processors,feasibility to realize warm restart is analyzed,and software and hardware project solutions are provided. Experimental results show that warm restart can effectively solve the disadvantage caused by cold restart in integrated avionics system.
