摘要
在机载通信中,ARINC429协议总线是一种常见的手段,它采用异步时钟控制,一发多收模式,单工传输数据,以其灵活、高速、稳定等特性被广泛应用于现代航空电子通信系统。为保障通信正常,ARINC429协议总线需采用一定的通信中断判故机制,实时监测数据的传输情况,本文针对一起偶发ARINC429协议总线心跳故障案例,通过分析故障成因,设计出一种合理的ARINC429协议总线通信中断判故机制。
In airborne communication,arinc429 protocol bus is a common means that adopts asynchronous clock control,one receiving mode,multiplex transmission of data,which is widely used in modern avionics communication systems with its flexible,high-speed and stable characteristics.To ensure normal communication,the ARINC429 protocol bus should adopt a certain communication interruption adjudication mechanism to monitor data transmission in real time.A heartbeat fault of ARINC429 bus is introduced in this paper.A method of fault estimation is provided by fault analysis.
