机载维护系统作为飞机不可或缺的功能和保障系统，对飞机的日常维修和运营成本有着重要影响。机载维护仿真平台是对我国民用飞机机载维护系统的前期探索和验证。文中针对维护系统与其它成员系统之间的复杂交联特点,提出了一种机载维护仿真平台的独特架构设计,详细阐述了仿真平台的功能设计，利用灵活的用户人机交互界面和嵌入式计算机系统实现了机载维护系统的故障诊断和隔离功能，模拟了飞机状态监控参数的动态传输过程。最后，通过成员激励系统和仿真平台的交互实验，验证了仿真平台设计思路的有效性与实用性，证明了机载维护系统各项功能的正确性。

Abstract:

As an indispensable function and support system of civil airplane, Onboard Maintenance System has an important influence on routine maintenance and the operating costs of airplane. The simulation platform of onboard maintenance is the early exploration and verification of onboard maintenance system. In view of the complex cross-linking characteristics between maintenance system and other membership systems, this paper proposes a uniquely architectural design for simulation platform, describes the functional design of simulation platform in details, realizes the function of fault diagnosis and failure isolation for onboard maintenance system using the flexible user interface and embedded computer system, simulates the dynamic transfer process for the parameter of aircraft condition monitoring. At last, it verifies the effectiveness and practicality of simulation platform, proves the correctness of functions of onboard maintenance system through the interactive experiment between membership excitation system and simulation platform.
