摘要
随着民用机载技术的发展,动态可重构技术已逐渐成为提高机载系统设计可靠性、安全性的关键。然而,随着该技术的引入,动态重构系统的模型建立以及可靠性分析问题日益突显。文章通过分析综合显示系统显示器的动态重构过程,建立Simulink/Stateflow功能模型。基于马尔可夫随机过程理论对显示系统中显示器的重构过程建立可靠度数学模型,并推导出可靠度结果。该方式能够在系统研制初期快速有效的完成模型的建立,进行系统工作状态的模拟仿真以及可靠性分析,提高系统研发效率。
With the development of civil airborne technology, dynamic reconfigurable techniques have gradually become the key to improving the design reliability and safety of airborne systems. However, with the introduction of such technology, the modeling and reliability analysis of dynamic reconstruction systems become a problem. By analyzing the dynamic reconstruction process of the monitors in integrated display system, a Simulink/Stateflow functional model is established. Based on Stateflow model, reliability mathematical model is built and the reliability results are derived. This method can complete the establishment of the model in the initial stage of system development, conduct the simulation of the system working state and the reliability analysis, and so improve the efficiency of system development.
