针对飞行控制计算机对数据采集处理的要求,文章给出离散量采集处理的设计方案。方案首先介绍了飞行控制计算机中离散量输入信号的类型,然后介绍离散量采集处理及机内自检测(BIT)的流程,最后针对的不同形式的离散量,分别给出不同的采集处理及自检测方法,包括具体的原理框图和计算方法。该离散量采集处理方案硬件接口简洁、实时性强、抗干扰特性好,在飞行控制计算机中具有很强的实用性。
According to the requirements of flight control computer for data acquisition and processing, the article gives the design of discrete acquisition and processing. The scheme firstly introduces the types of discrete input signals in flight control computer, and then introduces the process of discrete acquisition processing and in-machine self-testing (BIT). Finally, different types of discrete quantities are given, Detection methods, including the specific block diagram and calculation methods. The discrete acquisition and processing program hardware interface is simple, real-time, anti-jamming features good, in the flight control computer has a strong practicality.
