摘　　要：针对某飞行器系统的工作状态测试以及各接口匹配情况的测试任务，设计并实现了一种飞行器地面测试系统。系统硬件采用分体设计，包括远端地面测试设备与近端地面供电控制设备。系统软件采用前后台框架设计，前台程序基于．NET开发，提供友好的人机交互界面，后台程序由RTX提供实时驱动，为实时单任务线程。后台线程以最高优先级的运行方式独占系统内核，且不能被中断和抢占，并以动态链接库的形式与前台程序交换数据。系统采用该结构方式可降低软硬件的开发难度，提高系统测试的实时性与稳定性，已成功应用到某飞行器的地面测试任务。In order to test the working status and interface matching condition of the aircraft, a ground test sys- tem （GTS） is designed and implemented. The GTS consists of ground test equipment and ground power control equipment. The foreground and background framework is adopted to develop the testing software. The front part uses . NET to provide the friendly user-interface, and the back part which is encapsulated as DLL runs with the real time kernel under RTX considering of the real-time requirements. In addition, the back part with the high- est priority mode of operation, and cannot be interrupted and preempted. This architecture not only reduces the system complexity, but also improves the real time property and system stability. The system has been success- fully applied to the ground test task of a certain aircraft.
