当控制系统将外部信息输入微计算机中去的时候,外界干扰也会通过输入口随之而入。干扰可能有不同的形式,诸如电磁干扰、电磁波干扰、电脉冲干扰等,但是,从输入口来看,却都是一些幅度、宽度不等的随机尖脉冲。抗干扰软件设计的任务,就是要识别真伪信息,摈弃干扰,留下有用的信号。本文介绍我们在软件设计中的几种不同的抗干扰软件设计方法。
When the control system inputs the external information into the microcomputer, the external interference also enters through the input port. Interference may have different forms, such as electromagnetic interference, electromagnetic interference, electrical pulse interference, but from the input point of view, but are some amplitude, width, random spikes. Anti-jamming software design task is to identify the authenticity of information, to abandon the interference, leaving a useful signal. This article describes several different software design methods we use in software design.
