摘要
AFDX总线是一种全双工、高数据率、双冗余的总线,现已被应用于新一代飞机,它具有可靠性高、稳定性和实时性好的优点。针对其优点,提出了一种以AFDX总线为通信协议的驾驶舱仿真方案。该方案以AFDX交换机为核心,用模块化划分各个终端系统(ES)并建立网络系统,交换机负责整个网络的终端系统间的数据管理。在此基础上提出了整个模拟器系统的总体结构,驾驶舱硬件仿真设备终端系统的接口电路设计,并进一步提出数据传输协议以满足传输实时性的要求。
AFDX is a full duplex, high data rate, the dual redundant bus, which has been used in a new genera tion of aircraft. It has advantages of high reliability, good stability and realtime. According to these advantages, a cockpit simulation scheme with AFDX bus as communication protocol is put forward, which takes AFDX switch as the core, partitions each terminal system to establish network by modularization. The switch is respon sible for the whole data management between its network terminal system. The overall structure of the simulator system is proposed, the interface circuit of cockpit hardware simulation equipment terminal system is designed and a data transmission protocol is further put forward to meet the requirements of realtime transmission.
