某工程飞行模拟器中便携式数字测试仪的研究

Abstract

工程飞行模拟器是一个复杂的人机半实物仿真系统，是研制新型飞机不可缺少的设备。开发成本高；占用空间场地大；不便于异地迁移。尤其当试飞现场飞机发生故障时，无法在复杂的现场环境发挥工程飞行模拟器的作用。本文研究的工程飞行模拟器便携式数字测试仪，是工程飞行模拟器的一个子系统。它具有支持试飞现场测试；通用；携带方便等特点。文中重点讨论了便携式测试仪的自定式测试界面设计；集成式测试控件设计及多种数据总线接口转换等问题。Engineering flight simulator is a complicated semi-physical simulation system, which is the indis-pensable equipment for developing new aircraft. It has high cost of development, space site, and does not facilitate offsite migration. Especially, when failure occurs at the plane test site, engi-neering flight simulator cannot play the role well in the complex environment of the scene. Engi-neering Flight Simulator portable digital test instrument of this research is a sub system of engi-neering flight simulator. It has the support of flight test on site; general; easy to carry. This paper mainly discussed the self-design of test interface of a portable test instrument, problems of inte-grated test control design, a variety of data bus interface transitions, etc.
