摘要
AFDX网络端系统实现符合ARINC664P7协议的网络数据的传输功能,在AFDX网络端系统数据接收方面,总结了AFDX网络数据的特点,分析了查询接收方式和中断接收方式各自的不足,设计并实现了一种基于查询和中断的混合式数据接收方法。该方法在保证查询接收方式高效的前提下,有效降低了对主机系统处理器资源的占用,并解决了中断接收方式引起的丢包问题。
AFDX end system implementation complies with the data transport function of ARINC664P7 protocol, this paper focus on the data receiving method of the AFDX end system, summarizes the characteristics of the AFDX network data, analyzes the shortage of both polling receive method and interrupt receive method, and then designs and implements a method with both merits of polling and intenupt. With this method, AFDX end system receives data more efficiently, and reduces the burden of using the host system＇s CPU resources, also resolves the loss of data problem with interrupt data receiving method.
