摘要
为了对综合模块化航空电子(IMA)系统的健康管理功能进行验证,给出了通过航空电子全双工交换式以太网(AFDX)进行故障注入的技术解决方案。在该方案下,提出了故障数据的配置管理方法,以及一种解决主机数据更新间隔、发送间隔与AFDX端系统定时器周期不匹配的发送策略,搭建了相应故障注入装置,开发了故障注入软件,通过实验测试说明了上述方法和策略的有效性。
Abstract
In order to verify the function of health management of Integrated Modular Avionics (IMA),a method of fault injection through AFDX network is proposed.This method contains a way to configure fault data and a data transmition strategy to solve the mismatching problem between the data rate and the period of the timer on PC.The environment for fault injection is established and the corresponding software is developed.The experiments conducted verifies the validity of the way and the strategy.
