基于虚拟仪器技术的直升机航电信号仿真系统设计

The Avionics Signal Simulation System of Helicopter Based on Virtual Instrument

本文针对航空电子系统地面联试时,有些设备不能按时交付或需要做修改不在试验现场,需要对其他系统进行测试的问题,设计了一套信号仿真系统,该系统运用虚拟仪器技术增强了可操作性。文中介绍了系统的软硬件组成,并举例介绍了仿真程序的开发过程。

For the problem of some equipments can't be delivered on schedule,but other equipments must be tested in some helicopter's avionics ground test.A suit of signal simulation system is designed in this paper.The system boosted up the maneuverability by using virtual instrument technology.The paper presents the composing of software and hardware,and illustrates the development process of simulation program.
