摘要
针对直升机航空电子通信系统中MIL-STD-1553B等总线通信协议传输率低、容错能力有限等问题,本文设计了一种基于FC-AE-ASM协议的光纤通道接口卡,实现了高实时、高可靠、高带宽、低传输延迟的长距离传输功能。最后搭建测试环境进行验证,实验结果表明,该光纤通道接口卡能够高速、正确的收发数据,满足直升机航空电子系统的需求。
In view of the problems of low transmission rate and limited fault tolerance of bus communication protocols such as MIL-STD-1553 Bin helicopteravionics communication system,a fiber channel interface card based on FC-AE-ASM protocol is designed to realize long distance transmission with high real-time,high reliability,high bandwidth and low transmission delay.Finally,a test environment is set up to verify the performance.The experimental results show that the interface card can send and receive data correctlyat high speed and can meet the requirements of helicopter avionics communication system.
