飞行控制计算机中的BIT技术及其测试方法

BIT Techniques and Test Methods of Flight Control Computer

随着电传飞行控制系统的加速发展,对于系统的可靠性要求越来越高,为提高其可靠性,采用了机内自检测(Built in test,BIT)技术,实现分系统级或者功能单元级的功能及性能自检测、自诊断。飞行控制系统中BIT的许多功能都是由飞行控制计算机产生和控制的。介绍了飞行控制计算机中的BIT,可以实现飞行控制计算机的自检测,提高其可靠性。

The reliability of FBW （ Fly- by- wire） flight control system is improved with the high speed development of FBW flight control system. To improve reliability of FBW flight control system, BIT （ Built in test） technique which can realize the self-test of subsystems or function units are used. Many BIT test methods of flight control system are realized and controlled by flight control computer. Detailed states BIT techniques of flight control computer, which can achieve built- intest and improve the reliability of flight control computer.
