摘要 为了统一航空电子装备各分系统的时钟,在深入分析航空电子系统结构的基础上,提出了利用航空总线将通信导航识别(CNI)系统的时钟作为基准,根据IEEE1588协议发送到其他电子设备,从而实现时钟统一的方案。通过对初始时间的误差分析表明,该方案能够满足实现航空电子装备时钟统一的要求。 A clock synchronization scheme is given based on deep analyses of avionic equipment structure. The clock of Communication, Navigation and Identification(CNI) system is transferred to other avionic equipments as a basis according to IEEE1588 protocol. Error analyses of this scheme show that it can meet the requirement of clock synchronization for avionics equipments.
