【摘要】 综合模块化航空电子(IMA)是机载航空电子系统发展的必然趋向，并进一步朝着深度综合化的方向发展。综合模块化使得系统的功能、性能、可靠性、可维护性有大提升的同时，在开发、维护、升级的费用上也能得到有效控制。IMA通过对闲置资源的分配，提高资源的使用效率，提高系统的综合效益。如何在保证安全性的前提下为航电中的各个子系统分配合适的共享资源，并能保证功能的完整性，是IMA系统开发中的一个重点。为了有效实现系统配置，需要一套可以验证资源配置合理性的工具，并针对任务对资源的需求，对资源进行统一配置，从而最大化地发挥IMA的优势，提高系统的任务处理能力。本文首先对综合模块化航空电子系统的系统架构和开发过程进行了研究，并基于DO-297规范阐述了IMA资源的基本概念、表示方法以及IMA资源配置流程，为IMA资源配置工具的开发提供理论支撑和标准依据。其次，对IMA资源配置过程中关于资源一致性和完整性需求进行了描述，并阐述了其验证方法。最后，基于对IMA资源配置流程和验证的研究，完成了对IMA资源的建模，并基于EMF实现相应的IMA资源配置工具——ACT。论文重点阐述了ACT工具的需求分析、系统设计以及所采用的关键技术，并以ATA38水处理系统的设计与配置作为应用案例，利用ACT对其进行配置，结果验证了所开发的工具ACT能够应用到实际的航电工程中。更多还原

【Abstract】 Integrated Modular Avionics (IMA) is inevitable trend of avionics development, and towards tothe depth integration in the future. It makes a big breakthrough in system function, performance,reliability, maintainability, and at the same time, gets effective control on funds in development,maintenance and upgrade. IMA improves the efficiency in the use of resources and overall efficiencyof the system by allocating spare resources. It is a key point in the development of IMA system todistribute shared resources for each subsystem of avionics without compromising safety and integrity.A set of tool for the verification of resources allocation is necessary to realize system configurationeffectively, and by configuring resource uniformity according to the resource requirements of tasks,the advantages of IMA can be maximized and the ability of the system task processing can beimproved.Firstly, the system architecture and development process of the integrated modular avionicssystems is researched in this paper, and the basic concept and representation of IMA resources isexpatiated as well as the IMA resource allocation process based on DO-297, which providestheoretical support and reference standard for the IMA resource configuration tool.Secondly, the resource integrity and consistence during the process of IMA resource allocation isdescribed, and the verification method is elaborated.Finally, the IMA resource is modeled, the corresponding IMA resource configuration tool (ACT)is implemented on the basis of EMF. The paper focuses on the requirement analysis, system designand the key technology of the ACT tool, and with the design and configuration of ATA38watertreatment system as an application case, it is proved that the ACT can be applied to engineeringpractice in avionics.更多还原
